Assessment of motor control may involve several health professionals depending on the affected individual's situation, and the severity of their condition. This may include physical therapists, physicians (including neurologists and psychiatrists ) and rehabilitation physicians, orthotists, occupational therapists, and speech-language pathologists. Assessment is needed of the affected individual's goals, their function, and any symptoms that may be related to the movement disorder, such as pain. A thorough assessment then uses a clinical reasoning approach to determine why difficulties are occurring. Elements of assessment will include analysis of posture, active movement, muscle strength, movement control and coordination, and endurance, as well as muscle tone and spasticity. Impaired muscles typically demonstrate a loss of selective movement, including a loss of eccentric control (decreased ability to actively lengthen); this decreased active lengthening of a muscle is a key factor that limits motor control. While multiple muscles in a limb are usually affected in the Upper Motor Neuron Syndrome, there is usually an imbalance of muscle activity (muscle tone), such that there is a stronger pull on one side of a joint, such as into elbow flexion. Decreasing the degree of this imbalance is a common focus of muscle strengthening programs. Impaired motor control also typically features a loss of stabilisation of an affected limb or the head from the trunk, so a thorough assessment requires this to be analysed as well, and exercise to improve proximal stability may be indicated.

Secondary effects are likely to impact on assessment of impaired muscles. If muscle tone is assessed with passive muscle lengthening, increased muscle stiffness may affect the feeling of resistance to passive stretch, in addition to neurological resistance to stretch. Other secondary changes such as loss of muscle fibres following acquired muscle weakness are likely to compound the weakness arising from the upper motor neuron lesion. In severely affected muscles, there may be marked secondary changes, such as muscle contracture, particularly if management has been delayed or absent.

The prognosis for those with spastic muscles depends on multiple factors, including the severity of the spasticity and the associated movement disorder, access to specialised and intensive management, and ability of the affected individual to maintain the management plan (particularly an exercise program). Most people with a significant UMN lesion will have ongoing impairment, but most of these will be able to make progress. The most important factor to indicate ability to progress is seeing improvement, but improvement in many spastic movement disorders may not be seen until the affected individual receives help from a specialised team or health professional.

Therapeutic interventions are best individualized to particular patients.

Basic principles of treatment for hypertonia are to avoid noxious stimuli and provide frequent range of motion exercise.

The term "hypotonia" comes from the Ancient Greek ὑπο- ("hypo-"), "under" and τόνος ("tónos"), from τείνω ("teinō"), "to stretch". Other terms for the condition include:

Doublecortin positive cells, Similar to stem cells, are extremely adaptable and, when extracted from a brain, cultured and then re-injected in a lesioned area of the same brain, they can help repair and rebuild it. The treatment using them would take some time to be available for general public use, as it has to clear regulations and trials.

Physiotherapy has been shown to be effective in controlling hypertonia through the use of stretching aimed to reduce motor neuron excitability. The aim of a physical therapy session could be to inhibit excessive tone as far as possible, give the patient a sensation of normal position and movement, and to facilitate normal movement patterns. While static stretch has been the classical means to increase range of motion, PNF stretching has been used in many clinical settings to effectively reduce muscle spasticity.

Icing and other topical anesthetics may decrease the reflexive activity for short period of time in order to facilitate motor function. Inhibitory pressure (applying firm pressure over muscle tendon) and promoting body heat retention and rhythmic rotation (slow repeated rotation of affected body part to stimulate relaxation) have also been proposed as potential methods to decrease hypertonia. Aside from static stretch casting, splinting techniques are extremely valuable to extend joint range of motion lost to hypertonicity. A more unconventional method for limiting tone is to deploy quick repeated passive movements to an involved joint in cyclical fashion; this has also been demonstrated to show results on persons without physical disabilities. For a more permanent state of improvement, exercise and patient education is imperative. Isokinetic, aerobic, and strength training exercises should be performed as prescribed by a physiotherapist, and stressful situations that may cause increased tone should be minimized or avoided.

Treatment should be based on assessment by the relevant health professionals. For muscles with mild-to-moderate impairment, exercise should be the mainstay of management, and is likely to need to be prescribed by a physical therapist or other health professional skilled in neurological rehabilitation.

Muscles with severe impairment are likely to be more limited in their ability to exercise, and may require help to do this. They may require additional interventions, to manage the greater neurological impairment and also greater secondary complications. These interventions may include serial casting, flexibility exercise such as sustained positioning programs, and medical interventions.

Research has clearly shown that exercise is beneficial for impaired muscles, even though it was previously believed that strength exercise would "increase" muscle tone and impair muscle performance further. Also, in previous decades there has been a strong focus on other interventions for impaired muscles, particularly stretching and splinting, but the evidence does not support these as effective. One of the challenges for health professionals working with UMNS movement disorders is that the degree of muscle weakness makes developing an exercise programme difficult. For muscles that lack any volitional control, such as after complete spinal cord injury, exercise may be assisted, and may require equipment, such as using a standing frame to sustain a standing position. Often, muscles require specific stimulation to achieve small amounts of activity, which is most often achieved by weight-bearing (e.g. positioning and supporting a limb such that it supports body weight) or by stimulation to the muscle belly (such as electrical stimulation or vibration).

Medical interventions may include such medications as baclofen, diazepam, dantrolene, or clonazepam. Phenol injections or botulinum toxin injections into the muscle belly can be used to attempt to dampen the signals between nerve and muscle. The effectiveness of medications varies between individuals, and varies based on location of the upper motor neuron lesion (in the brain or the spinal cord). Medications are commonly used for movement disorders, but research has not shown functional benefit for some drugs. Some studies have shown that medications have been effective in decreasing spasticity, but that this has not been accompanied by functional benefits.

The approach to diagnosing the cause of hypotonia (as with all syndromes in neurology) is first localization. The physician must first determine if the hypotonia is due to muscle, neuromuscular junction, nerve, or central cause. This will narrow the possible causes. If the cause of the hypotonia is found to lie in the brain, then it can be classified as a cerebral palsy. If the cause is localized to the muscles, it can be classified as a muscular dystrophy. If the cause is thought to be in the nerves, it is call hypotonia due to polyneuropathy. Many cases cannot be definitively diagnosed.

Diagnosing a patient includes obtaining family medical history and a physical examination, and may include such additional tests as computerized tomography (CT) scans, magnetic resonance imaging (MRI) scans, electroencephalogram (EEG), blood tests, genetic testing (such as chromosome karyotyping and tests for specific gene abnormalities), spinal taps, electromyography muscle tests, or muscle and nerve biopsy.

Mild or benign hypotonia is often diagnosed by physical and occupational therapists through a series of exercises designed to assess developmental progress, or observation of physical interactions. Since a hypotonic child has difficulty deciphering his spatial location, he may have some recognizable coping mechanisms, such as locking the knees while attempting to walk. A common sign of low-tone infants is a tendency to observe the physical activity of those around them for a long time before attempting to imitate, due to frustration over early failures. Developmental delay can indicate hypotonia.

Meige's is commonly misdiagnosed and most doctors will have not seen this condition before. Usually a neurologist who specializes in movement disorders can detect Meige's. There is no way to detect Meige's by blood test or MRI or CT scans. OMD by itself may be misdiagnosed as TMJ.

The lack of prompt response to anticholinergic drugs in cases of idiopathic Meige's syndrome is important in differentiating it from acute dystonia, which does respond to anticholinergics.

Diagnosis can be achieved through a specialized form of electromyographic (EMG) testing called the long exercise test. This test measures the amplitude of a nerve response (called the Compound Muscle Action Potential or CMAP) for 40 to 50 minutes following a few minutes of exercise. In affected patients, there is a progressive fall in the amplitude of the potential. Besides the patient history or a report of serum potassium low normal or low during an attack, the long exercise test is the current standard for medical testing. Genetic diagnosis is often unreliable as only a few of the more common gene locations are tested, but even with more extensive testing 20–37% of people with a clinical diagnosis of hypokalemic periodic paralysis have no known mutation in the two known genes. Standard EMG testing cannot diagnose a patient unless they are in a full blown attack at the time of testing. Provoking an attack with exercise and diet then trying oral potassium can be diagnostic, but also dangerous as this form of PP has an alternate form known as hyperkalemic periodic paralysis. The symptoms are almost the same, but the treatment is different. The old glucose insulin challenge is dangerous and risky to the point of being life-threatening and should never be done when other options are so readily available.

People with hypokalemic periodic paralysis are often misdiagnosed as having a conversion disorder or hysterical paralysis since the weakness is muscle-based and doesn't correspond to nerve or spinal root distributions. The tendency of people with hypokalemic periodic paralysis to get paralyzed when epinephrine is released in "fight or flight" situations further adds to the temptation to misdiagnose the disorder as psychiatric.

Evaluation of a child with torticollis begins with history taking to determine circumstances surrounding birth and any possibility of trauma or associated symptoms. Physical examination reveals decreased rotation and bending to the side opposite from the affected muscle. Some say that congenital cases more often involve the right side, but there is not complete agreement about this in published studies. Evaluation should include a thorough neurologic examination, and the possibility of associated conditions such as developmental dysplasia of the hip and clubfoot should be examined. Radiographs of the cervical spine should be obtained to rule out obvious bony abnormality, and MRI should be considered if there is concern about structural problems or other conditions.

Ultrasonography is another diagnostic tool that has high frequency sound waves used to visualize the muscle tissue. A colour histogram can also be used to determine cross sectional area and thickness of the muscle.

Evaluation by an optometrist or an ophthalmologist should be considered in children to ensure that the torticollis is not caused by vision problems (IV cranial nerve , nystagmus-associated "null position," etc.).

Differential diagnosis for torticollis involves

- Cranial nerve IV palsy

- Spasmus nutans

- Sandifer syndrome

- Myasthenia gravis

Cervical dystonia appearing in adulthood has been believed to be idiopathic in nature, as specific imaging techniques most often find no specific cause.

Treatment of primary dystonia is aimed at reducing symptoms such as involuntary movements, pain, contracture, embarrassment, and to restore normal posture and improve the patient’s function. This treatment is therefore not neuroprotective. According to the European Federation of Neurological Sciences and Movement Disorder Society, there is no evidence-based recommendation for treating primary dystonia with antidopaminergic or anticholinergic drugs although recommendations have been based on empirical evidence. Anticholinergic drugs prove to be most effective in treating generalized and segmental dystonia, especially if dose starts out low and increases gradually. Generalized dystonia has also been treated with such muscle relaxants as the benzodiazepines. Another muscle relaxant, baclofen, can help reduce spasticity seen in cerebral palsy such as dystonia in the leg and trunk. Treatment of secondary dystonia by administering levodopa in dopamine-responsive dystonia, copper chelation in Wilson’s disease, or stopping the administration of drugs that may induce dystonia have been proven effective in a small number of cases. Physical therapy has been used to improve posture and prevent contractures via braces and casting, although in some cases, immobilization of limbs can induce dystonia, which is by definition known as peripherally induced dystonia. There are not many clinical trials that show significant efficacy for particular drugs, so medical of dystonia must be planned on a case-by-case basis. Botulinum toxin B, or Myobloc, has been approved by the US Food and Drug Administration to treat cervical dystonia due to level A evidential support by the scientific community. Surgery known as GPi DBS (Globus Pallidus Pars Interna Deep Brain Stimulation) has come to be popular in treating phasic forms of dystonia, although cases involving posturing and tonic contractions have improved to a lesser extent with this surgery. A follow-up study has found that movement score improvements observed one year after the surgery was maintained after three years in 58% of the cases. It has also been proven effective in treating cervical and cranial-cervical dystonia.

Diagnostic procedures that may reveal muscular disorders include direct clinical observations. This usually starts with the observation of bulk, possible atrophy or loss of muscle tone. Neuromuscular disease can also be diagnosed by testing the levels of various chemicals and antigens in the blood, and using electrodiagnostic medicine tests including electromyography (measuring electrical activity in muscles) and nerve conduction studies.

In neuromuscular disease evaluation, it is important to perform musculoskeletal and neurologic examinations. Genetic testing is an important part of diagnosing inherited neuromuscular conditions.

Treatment of tics present in conditions such as Tourette’s syndrome begins with patient, relative, teacher and peer education about the presentation of the tics. Sometimes, pharmacological treatment is unnecessary and tics can be reduced by behavioral therapy such as habit-reversal therapy and/or counseling. Often this route of treatment is difficult because it depends most heavily on patient compliance. Once pharmacological treatment is deemed most appropriate, lowest effective doses should be given first with gradual increases. The most effective drugs belong to the neuroleptic variety such as monoamine-depleting drugs and dopamine receptor-blocking drugs. Of the monoamine-depleting drugs, tetrabenazine is most powerful against tics and results in fewest side effects. A non-neuroleptic drug found to be safe and effective in treating tics is topiramate. Botulinum toxin injection in affected muscles can successfully treat tics; involuntary movements and vocalizations can be reduced, as well as life-threatening tics that have the potential of causing compressive myelopathy or radiculopathy. Surgical treatment for disabling Tourette’s syndrome has been proven effective in cases presenting with self-injury. Deep Brain Stimulation surgery targeting the globus pallidus, thalamus and other areas of the brain may be effective in treating involuntary and possibly life-threatening tics.

Some cases of myotonia congenita do not require treatment, or it is determined that the risks of the medication outweigh the benefits. If necessary, however, symptoms of the disorder may be relieved with quinine, phenytoin, carbamazepine, mexiletine and other anticonvulsant drugs. Physical therapy and other rehabilitative measures may also be used to help muscle function. Genetic counseling is available.

The prognosis for periodic paralysis varies. Overactivity, a diet that is not low in sodium and carbohydrates, or simply an unfortunate gene mutation can lead to a type of chronic, low level weakness called an "abortive attack," or to permanent muscle damage. Abortive attacks often respond to extra potassium, cutting carbohydrates, getting plenty of rest, increasing doses of medication and gentle daily exercise such as short walks. Permanent muscle weakness is just what it sounds like: Permanent, irreparable damage to the muscles and associated weakness. Vacuoles and tubular aggregates form in and destroy healthy muscle tissue. This type of damage can typically be observed via a muscle biopsy. Not even anabolic steroids can repair this type of muscular damage.

Life span is expected to be normal, but attacks can drop potassium to levels low enough to cause life-threatening breathing problems or heart arrhythmia. Patients often report muscle pain and cognitive problems during attacks. Migraines occur in up to 50% of all hypokalemic periodic paralysis patients and may include less common symptoms like phantom smells, sensitivity to light and sound or loss of words. Medical literatures states that muscle strength is normal between attacks, but patients often report that their baseline strength is in fact lower than that of healthy individuals.

Because there are dozens of possible gene mutations, some drugs and treatments that work fine for one patient will not work for another. For example, most patients do well on acetazolamide, but some don't. Some patients will do well with extra magnesium (the body's natural ion channel blocker) or fish oil, while these same nutrients will make other patients worse. Patients and caregivers should take extreme caution with all new drugs and treatment plans.

A diagnostic test for statin-associated auto-immune necrotizing myopathy will be available soon in order to differentiate between different types of myopathies during diagnosis. The presence of abnormal spontaneous electrical activity in the resting muscles indicates an irritable myopathy and is postulated to reflect the presence of an active necrotising myopathic process or unstable muscle membrane potential. However, this finding has poor sensitivity and specificity for predicting the presence of an inflammatory myopathy on biopsy. Further research into this spontaneous electrical activity will allow for a more accurate differential diagnosis between the different myopathies.

Currently a muscle biopsy remains a critical test, unless the diagnosis can be secured by genetic testing. Genetic testing is a less invasive test and if it can be improved upon that would be ideal. Molecular genetic testing is now available for many of the more common metabolic myopathies and muscular dystrophies. These tests are costly and are thus best used to confirm rather than screen for a diagnosis of a specific myopathy. Due to the cost of these tests, they are best used to confirm rather than screen for a diagnosis of a specific myopathy. It is the hope of researchers that as these testing methods improve in function, both costs and access will become more manageable

The increased study of muscle pathophysiology is of importance to researchers as it helps to better differentiate inflammatory versus non-inflammatory and to aim treatment as part of the differential diagnosis. Certainly classification schemes that better define the wide range of myopathies will help clinicians to gain a better understanding of how to think about these patients. Continued research efforts to help appreciate the pathophysiology will improve clinicians ability to administer the most appropriate therapy based on the particular variety of myopathy.

The mechanism for myopathy in individuals with low vitamin D is not completely understood. A decreased availability of 250HD leads to mishandling of cellular calcium transport to the sarcoplasmic reticulum and mitochondria, and is associated with reduced actomyosin content of myofibrils.

A patient's history is one of the key factors in diagnosing acquired noninflammatory myopathy. The history is used not only to analyze the time frame with which the patient began to express symptoms, but to also see if the disease is within the patient's family's history, to check medication or drug use history, and to see if the patient has suffered any trauma due to illness or infection. Basic exams will test for where the muscle weakness is and how weak it is. This is performed by testing for proximal and distal muscle strength, as well as testing for any signs of neurogenic symptoms such as impaired sensation, deep tendon reflexes, and atrophy.

If needed, more advanced equipment can be used to help determine whether a patient is suffering from ANIM. This includes:

- Measurement of serum levels of muscle enzymes

- Electromyography (EMG)

- Magnetic Resonance Imaging (MRI)

- Muscle biopsy

When examining the serum levels of muscle enzymes, the relative levels of creatine kinase, aldolase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase are closely examined. Abnormal levels of these proteins are indicative of both inflammatory myopathy and ANIM.

EMGs are particularly useful in locating the affected muscle groups, as well as determining the distribution of the myopathy throughout the cell. EMGs measure several indicators of myopathies such as:

- The spontaneous electrical movement from a single muscle fiber at rest,

- Measurement of a polyphasic, shorter amplitude, motor unit action potential during muscle stimulation,

- Determining that the muscle group cannot differentiate large motor plate stimulation from small motor plate stimulation involved in recruitment of muscle fibers.

Magnetic Resonance Imaging will elicit edema in inflammatory patients, but it will most likely show nothing in patients with ANIM and if it does, it will show some atrophy.

If an individual's ANIM is a result of a metabolite defect, then additional tests are required. These tests are directed at enzyme function at rest and during exercise, and enzyme intermediates. Molecular genetic testing is often used to determine if there was any predisposition to the expressed symptoms.

In northern Scandinavia, the prevalence of myotonia congenita has been estimated at 1:10,000.

Myotonia congenita is estimated to affect 1 in 1,000,000 people worldwide.

Diagnosis of ataxic cerebral palsy is based on clinical assessment using standardized assessment tools. Diagnosis begins with the observation of slow motor development, abnormal muscle tone, and unusual posture in children that fail to reach developmental milestones. Diagnosis differs in adults and children because a child’s brain is still developing and acquiring new motor, linguistic, adaptive, and social skills. The testing strategy is based on the pattern of development of symptoms, the patient’s family history, and any factors that might influence the diagnosis, such as injury or trauma. Associated disabilities such as those previously described under symptoms associated with ataxic cerebral palsy, i.e., sensory impairment and cognitive dysfunction, are also helpful in diagnosing the disease.

In children, assessment of infantile reflexes is also a diagnostic tool, such as the Moro reflex and the Romberg Test. The Moro reflex is rarely present in infants after 6 months of age and is characterized as a response to a sudden loss of support that causes the infant to feel like it is falling. The infant will respond by abduction and adduction (or spreading and unspreading) of the arms, as well as crying. The Moro reflex is significant in evaluating the integration of the central nervous system and patients with ataxic cerebral palsy will show a persistence and exacerbation of the reflex. In addition, patients with ataxic cerebral palsy will rarely show a positive Romberg test, which indicates that there is localized cerebellar dysfunction.

Physical diagnostic tests, such as cerebral imaging using Computerized Tomography (CT), Magnetic Resonance Imaging (MRI), and ultrasound are also useful, but not preferred to clinical assessments. These neuroimaging techniques can show brain abnormalities that have been found in previous patients with cerebral palsy, i.e., focal infarction and various brain malformations, however in a study of 273 children who were born after 35 weeks of gestation and underwent neuroimaging studies, one-third of the infants showed normal studies. In addition, infants undergo neuroimaging studies once the infant has neurological findings suggestive of cerebral palsy.

For developmental diagnosis in children and infants, there are a number of milestones of motor, linguistic, adaptive, and social behavior, such as.

1. When the child could sit up on their own with or without support

2. Say their first words

3. Feed themselves

4. Play successfully with children of same age

The main symptoms involve involuntary blinking and chin thrusting. Some patients may experience excessive tongue protrusion, squinting, light sensitivity, muddled speech, or uncontrollable contraction of the platysma muscle. Some Meige's patients also have "laryngeal dystonia" (spasms of the larynx). Blepharospasm may lead to embarrassment in social situations, and oromandibular dystonia can affect speech, making it difficult to carry on the simplest conversations. This can cause difficulty in both personal and professional contexts, and in some cases may cause patients to withdraw from social situations.

The condition tends to affect women more frequently than men.

A CT scan can distinguish muscle tissue from other tissues and thereby estimate the amount of muscle tissue in the body.

Fast loss of muscle tissue (relative to normal turnover), can be approximated by the amount of urea in the urine. The equivalent nitrogen content (in gram) of urea (in mmol) can be estimated by the conversion factor 0.028 g/mmol. Furthermore, 1 gram of nitrogen is roughly equivalent to 6 gram of protein, and 1 gram of protein is roughly equivalent to 4 gram of muscle tissue. Subsequently, in situations such as muscle wasting, 1 mmol of excessive urea in the urine (as measured by urine volume in litres multiplied by urea concentration in mmol/l) roughly corresponds to a muscle loss of 0.67 gram.

Muscle atrophy can be opposed by the signaling pathways which induce muscle hypertrophy, or an increase in muscle size. Therefore, one way in which not exercise induces an increase in muscle mass is to down regulate the pathways which have the opposite effect.

β-hydroxy β-methylbutyrate (HMB), a metabolite of leucine which is sold as a dietary supplement, has demonstrated efficacy in preventing the loss of muscle mass in several muscle wasting conditions in humans, particularly sarcopenia. A growing body of evidence supports the efficacy of HMB as a treatment for reducing, or even reversing, the loss of muscle mass, muscle function, and muscle strength in hypercatabolic disease states such as cancer cachexia; consequently, it is recommended that both the prevention and treatment of sarcopenia and muscle wasting in general include supplementation with HMB, regular resistance exercise, and consumption of a high-protein diet. Based upon a meta-analysis of seven randomized controlled trials that was published in 2015, HMB supplementation has efficacy as a treatment for preserving lean muscle mass in older adults. More research is needed to determine the precise effects of HMB on muscle strength and function in this age group.

Since the absence of muscle-building amino acids can contribute to muscle wasting (that which is torn down must be rebuilt with like material), amino acid therapy may be helpful for regenerating damaged or atrophied muscle tissue. The branched-chain amino acids or BCAAs (leucine, isoleucine, and valine) are critical to this process, in addition to lysine and other amino acids.

In severe cases of muscular atrophy, the use of an anabolic steroid such as methandrostenolone may be administered to patients as a potential treatment. A novel class of drugs, called SARM (selective androgen receptor modulators) are being investigated with promising results. They would have fewer side-effects, while still promoting muscle and bone tissue growth and regeneration. These claims are, however, yet to be confirmed in larger clinical trials.

One important rehabilitation tool for muscle atrophy includes the use of functional electrical stimulation to stimulate the muscles. This has seen a large amount of success in the rehabilitation of paraplegic patients.

Although treatment for tennis elbow prior 2010 was unknown because the etiology remained unclear, tests confirmed that the cause was an imbalance with the agonist-antagonist functional relationship. Treatment now includes anti-inflammatory medicines, rest, equipment check, physical therapy, braces, steroid injections, shock wave therapy and if symptoms persist after 6 to 12 months, doctors may recommend surgery.

Although treatment varies depending on how bad eye alignment is and also the underlying causes of strabismus. Treatment for strabismus may include orthoptics a term used for eye muscle training, this treatment can be provided by orthoptists and also optometrists. Other treatment may include wearing eye patches aimed at strengthening the weaker eye while inhibiting the stronger eye, an alternative to eye patches is the use of an opaque lens, other treatments may include eye drops to temporarily inhibit the stronger eye and at any age eye muscle surgery can be done to correct the muscular balance of the ocular muscles.

Although the cause of scoliosis can sometimes remain unknown (idiopathic scoliosis) there is treatment available that targets at strengthening the back muscles, for milder cases usually do not require medical attention, more severe cases require either muscle strengthening exercises aimed at the back muscles and even special back braces or surgery can be recommended if the case is extreme. Studies have shown that treatment with a special back brace among children ranging from 10–16 years can be successful and using this method of muscle training scoliosis can be cured with non-surgical treatment.

In terms of the mechanism of neurological diseases, it depends on which one—whether it is amyotrophic lateral sclerosis, myasthenia gravis or some other NMD. One finds that in muscular dystrophy (Duchenne), gene therapy might have promise as a treatment, since the mutation in a nonessential exon, can be improved via exon-skipping.
