Below is a list of criteria for diagnosing TMS, according to Schechter and Sarno:

- "Lack of known physical cause:" Schechter and Sarno state that a physical examination, tests and imaging studies is needed to rule out serious conditions, such as tumors. Sarno considers spinal disc herniations to generally be harmless, because he says the symptom location does not even correlate to the herniation location.

- "Tender points:" While medical doctors use eleven of eighteen tender points as a diagnostic criteria for fibromyalgia, Sarno states that he uses six main tender points to diagnose TMS: two tender points in the upper trapezius muscles, two in the lumbar paraspinal muscles and two in the lateral upper buttocks. He states that these are found in 99% of TMS patients.

- "History of other psychosomatic disorders:" Schechter and Sarno consider a prior history of other psychosomatic disorders an indication that the patient may have TMS. They list irritable bowel syndrome and tension headache as examples of psychosomatic disorders.

Schechter and Sarno state that if a patient is unable to visit a medical doctor who is trained in TMS, then the patient should see a traditional medical doctor to rule out serious disorders, such as fractures, tumors and infections.

While psychogenic pain and pain disorder are accepted diagnoses in the medical community, the TMS modality is more controversial.

A non-peer-reviewed 2005 study by Schechter at the Seligman Medical Institute (SMI), co-authored with institute director Arthur Smith, found that treatment of TMS achieved a 57% success rate among patients with chronic back pain.

A peer-reviewed 2007 study with Schechter, Smith and Stanley Azen, Professor and Co-Director of Biostatistics in the Department of Preventative Medicine at the USC Keck School of Medicine, found a 54% success rate for treatment of TMS ("P"<.00001). The treatment consisted of office visits, at-home educational materials, writing about emotional issues and psychotherapy. The average pain duration for the study's patients was 9 years. Patients with less than 6 months of back pain were excluded to "control for the confounder that most back pain episodes typically resolve on their own in a few weeks."

Schechter, Smith and Azen also compared their results to the results of three studies of other psychological treatments for chronic back pain. The three non-TMS studies were selected because of (a) their quality, as judged by the Cochrane Collaboration, and (b) the similarity of their pain measurements to those used in the TMS study. Of the three non-TMS studies, only one (the Turner study) showed a statistically significant improvement. Compared to the 2007 TMS study, the Turner study had a lower success rate (26%-35%, depending on the type of psychological treatment) and a lower level of statistical significance ("P"<.05).

Schechter, "et al." state that one advantage of TMS treatment is that it avoids the risks associated with surgery and medication, but they caution that the risks of TMS treatment are somewhat unknown due to the relatively low number of patients studied so far.

Prevention of MSDs relies upon identification of risk factors, either by self-report, observation on the job, or measurement of posture which could lead to MSDs. Once risk factors have been determined, there are several intervention methods which could be used to prevent the development of MSDs. The target of MSD prevention efforts is often the workplace in order to identify incidence rates of both disorders and exposure to unsafe conditions.

Assessment of MSDs are based on self-reports of symptoms and pain as well as physical examination by a doctor. Doctors rely on medical history, recreational and occupational hazards, intensity of pain, a physical exam to locate the source of the pain, and sometimes lab tests, x-rays, or an MRI Doctors look for specific criteria to diagnose each different musculoskeletal disorder, based on location, type, and intensity of pain, as well as what kind of restricted or painful movement a patient is experiencing. A popular measure of MSDs is the Nordic Questionnaire that has a picture of the body with various areas labeled and asks the individual to indicate in which areas they have experienced pain, and in which areas has the pain interfered with normal activity.

Anumonye reported treatment success with lorazepam; others found benefit with antidepressants and relaxation exercises.

Treatment may involve investigation, reassurance and explanation, and possibly specialist treatment such as antidepressants or cognitive behavioral therapy.

Diagnosis is largely based on patient description and relevant details about recent surgeries, hip injuries, or repetitive activities that could irritate the nerve. Examination checks for sensory differences between the affected leg and the other leg. Accurate diagnosis may require an abdominal and pelvic examination to exclude problems in those areas.

Electromyographic (EMG) nerve-conduction studies may be required. X-rays may be needed to exclude bone abnormalities that might put pressure on the nerve; likewise CT or MRI scans to exclude soft tissue causes such as a tumor.

Functional somatic syndromes may occur in 6 to 36% of the population.

Sudden cessation of high-dose corticosteroids, opioids, barbiturates, benzodiazepines, caffeine or alcohol can induce myalgia in many respects.

BFS has been reported in other African cultures, and also in Brazil, Argentina, and Ethiopian Jews. Historic higher reported prevalence among males may be due to more males being present in higher education in African countries. Studies since the 1990s have not verified gender differences. Other studies found a possible association with low socioeconomic status, an association with average or higher intelligence, and a high association with neuroticism. Individuals with BFS have been found to have problems with isolation, poor study habits, and the use of psychostimulants as well as physical changes including in muscle tension and heart rate.

In order to qualify a patient's condition as BSS, the bending angle must be greater than 45 degrees. While the presence of the condition is very easy to note, the cause of the condition is much more difficult to discern. Conditions not considered to be BSS include vertebral fractures, previously existing conditions, and ankylosing spondylitis. Lower-back CT scans and MRIs can typically be used to visualize the cause of the disease. Further identification of the cause can be done by histochemical or cellular analysis of muscle biopsy.

Camptocormia is becoming progressively found in patients with Parkinson's disease.

The diagnosis of Parkinson's-associated camptocormia includes the use of imaging of the brain and the spinal cord, along with electromyography or muscle biopsies.

Muscle biopsies are also a useful tool to diagnose camptocormia. Muscle biopsies found to have variable muscle fiber sizes and even endomysial fibrosis may be markers of bent spine syndrome. In addition, disorganized internal architecture and little necrosis or regeneration is a marker of camptocormia.

Patients with camptocormia present with reduced strength and stooped posture when standing due to weakened paraspinous muscles (muscles parallel to the spine). Clinically, limb muscles show fatigue with repetitive movements. Paraspinous muscles undergo fat infiltration. Electromyography may be used as well in diagnosis. On average, the paraspinous muscles of affected individuals were found to be 75% myopathic, while limb muscles were 50% percent myopathic. Creatine kinase activity levels in skeletal muscle are a diagnostic indicator that can be identifiable through blood tests.

The most common causes of myalgia by injury are: sprains and strains.

Treatment varies. In most cases, the best treatment is to remove the cause of compression by modifying patient behavior, in combination with medical treatment to relieve inflammation and pain. Whatever the cause, typical treatment takes several weeks to months—depending on the degree of nerve damage. Typical treatment options include:

- Active Release Technique (ART) soft tissue treatment

- Wearing looser clothing and suspenders rather than belts

- Weight loss if obesity is present

- Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammatory pain if pain level limits motion and prevents sleep

- Reducing physical activity in relation to pain level. Acute pain may require absolute bed rest

- Deep tissue massage to reduce tension in the gluteal muscles, most commonly the gluteus maximus. The tensor fasciae latae may also be implicated.

The lateral cutaneous nerve of the thigh can occasionally be damaged during laparoscopic hernia repair, or scarring from the operation can lead to meralgia paraesthetica.

For lower pain levels, treatment may involve having the patient:

- Seek appropriate physical therapy, such as stretching and massage, which plays a large role in the management of pain

- Learn to perform inguinal ligament stretching (from a physical therapist or from a YouTube video) which can rapidly relieve symptoms

- Use rest periods to interrupt long periods of standing, walking, cycling, or other aggravating activity

- Lose weight, and exercise to strengthen abdominal muscles

- Wear clothing that is loose at the upper front hip area

- Apply heat, ice, or electrical stimulation

- Take nonsteroidal anti-inflammatory medications for 7–10 days

- Remove hair in affected area (shave)

- Lidocaine patches (must shave area first)

- Titanium dioxide patches to interfere with the electrostatic effect of the nerves on the surface of the skin

Pain may take significant time (weeks) to stop and, in some cases, numbness persists despite treatment. In severe cases, the physician might perform a local nerve block at the inguinal ligament, using a combination of local anaesthetic (lidocaine) and corticosteroids to provide relief that may last several weeks. Pain modifier drugs for neuralgic pain (such as amitriptyline, carbamazepine or gabapentin) may be tried, but are often not as helpful in the majority of patients.

Persistent and severe cases may require surgery to decompress the nerve or, as a last resort, to resect the nerve. The latter treatment leaves permanent numbness in the area.

Many physicians also recommend changes in diet to treat chronic headaches. Many chronic headache sufferers fail to recognize foods or beverages as headache factors, because the consumption may not consistently cause headaches or the headaches may be delayed. Many of the chemicals in certain foods can cause chronic headaches, including caffeine, monosodium glutamate (MSG), nitrites, nitrates, tyramine, and alcohols. Some of the foods and beverages that chronic headache sufferers are advised to avoid include caffeinated beverages, chocolate, processed meats, cheese and fermented dairy products, fresh yeast-risen baked goods, nuts, and alcohol as well as certain fruits and vegetables. Additionally, people may have differing dietary triggers on an individualized basis, because not all foods affect people the same way. Different medical professionals suggest different ways of testing or changing diets. Some may suggest eliminating a few of the potentially headache-causing foods at a time for a short period of time, while others suggest removing all the threatening foods from a person's diet and slowly adding a couple back at a time. Yet, others may not suggest diet modification at all. The treatment of chronic headaches through changes in diet is based on personal opinion, and, therefore, controversial.

Chiropractic care involves in manipulation of the neck and spine to ensure proper alignment. A misalignment can cause headaches along with other problems in the body. The misalignment can compress nerves in the lower neck as well as cause muscle contractions in the neck and headaches can result.

Clinical studies have revealed that camptocormia may be hereditary; however, the inheritance mechanism remains unclear. Current areas of research include molecular and genetic studies aimed at elucidating a possible inheritance model along with molecular pathological mechanisms and proteins responsible for BSS. This research will help will facilitate improvement in the classification, diagnosis, and treatment of the condition. In addition, new technologies and animal models of postural abnormalities are being developed to understand camptocormia and design more effective treatment methods.

As of 2013 tension headaches affect about 1.6 billion people (20.8% of the population) and are more common in women than men (23% to 18% respectively). Despite its benign character, tension-type headache, especially in its chronic form, can impart significant disability on patients as well as burden on society at large.

Patients may be ashamed or actively attempt to disguise their symptoms. This can make diagnosis difficult as symptoms are not always immediately obvious, or have been deliberately hidden to avoid disclosure. If the patient admits to hair pulling, diagnosis is not difficult; if patients deny hair pulling, a differential diagnosis must be pursued. The differential diagnosis will include evaluation for alopecia areata, iron deficiency, hypothyroidism, tinea capitis, traction alopecia, alopecia mucinosa, thallium poisoning, and loose anagen syndrome. In trichotillomania, a hair pull test is negative.

A biopsy can be performed and may be helpful; it reveals traumatized hair follicles with perifollicular hemorrhage, fragmented hair in the dermis, empty follicles, and deformed hair shafts (trichomalacia). Multiple catagen hairs are typically seen. An alternative technique to biopsy, particularly for children, is to shave a part of the involved area and observe for regrowth of normal hairs.

IBM is often initially misdiagnosed as polymyositis. A course of prednisone is typically completed with no improvement and eventually sIBM is confirmed. sIBM weakness comes on over months or years and progresses steadily, whereas polymyositis has an onset of weeks or months. Other forms of muscular dystrophy (e.g. limb girdle) must be considered as well.

Though evidence for acupuncture is slight, some suggest it may be useful in those with frequent or chronic tension headaches.

People with tension-type headache often use spinal manipulation, soft tissue therapy, and myofascial trigger point treatment. Studies of effectiveness are mixed. A 2006 systematic review found no rigorous evidence supporting manual therapies for tension headache. A 2005 structured review found only weak evidence for the effectiveness of chiropractic manipulation for tension headache, and that it was probably more effective for tension headache than for migraine. A 2004 Cochrane review found that spinal manipulation may be effective for migraine and tension headache, and that spinal manipulation and neck exercises may be effective for cervicogenic headache. Two other systematic reviews published between 2000 and May 2005 did not find conclusive evidence in favor of spinal manipulation. A 2012 systematic review of manual therapy found that hands-on work may reduce both the frequency and the intensity of chronic tension-type headaches.

Elevated creatine kinase (CK) levels in the blood (at most ~10 times normal) are typical in sIBM but affected individuals can also present with normal CK levels. Electromyography (EMG) studies usually display abnormalities. Muscle biopsy may display several common findings including; inflammatory cells invading muscle cells, vacuolar degeneration, inclusions or plaques of abnormal proteins. sIBM is a challenge to the pathologist and even with a biopsy, diagnosis can be ambiguous.

A diagnosis of inclusion body myositis was historically dependent on muscle biopsy results. Antibodies to cytoplasmic 5'-nucleotidase (cN1A; NT5C1A) have been strongly associated with the condition. In the clinical context of a classic history and positive antibodies, a muscle biopsy might be unnecessary.

Most cases of back pain are related to issues in human musculoskeletal system and are not related to severe diseases. Musculoskeletal problems also called mechanical because many of them linked to vertebrae physical motions. Back pain itself is not considered a diagnosis, but rather a symptom of underlying (in most cases musculoskeletal) problems.

following:

- Vertebrae misalignment, which can cause nerve interference (also called subluxation), muscle tension, or muscle spasm

- Strained muscles

- Sprained ligaments

- Ruptured disks, which also called "slipped", or herniated disks

- Degenerative discs (lose their cushioning ability). The degeneration usually caused by repetitive strain, or injury, or aging.

- Irritated joints

BII phobia is one of the more common psychiatric disorders, affecting about 3 to 4% of the general population, and in about 80% of the BII phobia cases, the patient experiences syncope or presyncope. After a random survey was completed in Aligarh, India, with 1648 male and 1613 female, it was found that a significantly higher percentage of females compared to males had BII phobia; 23.36% of females were diagnosed with BII phobia while only 11.19% of males were diagnosed. Females also fainted more often than males, at 64.09% compared to a male rate of 39.4%.

Furthermore, only 5.3% of BII phobia patients reported to have visited the hospital once or twice for consultation about BII phobia, however, without engaging in any kind of treatment.

Another study, involving participants from all 50 states and the District of Columbia, ages 65 years and older, found that a total of 386 participants disclosed having BII Phobia throughout their whole lifetime, 90% of those cases consisted of patients dealing with BII Phobia as well as other lifetime fears.

Jumping Frenchmen of Maine syndrome must be distinguished from other conditions involving the startle reflex or tics.

Tourette syndrome is characterized by multiple physical (motor) tics and at least one vocal (phonic) tic. There are many overlaps when compared clinically, but the abnormal "jumping" response is always provoked, unlike the involuntary tics in Tourette syndrome.

Latah from Southeast Asia is a disorder where one's startle response is similar to a state of trance with repetitive speech or movements. Miryachit is a disorder found in Siberia that also displays an action similar to "jumping". Neurasthenia is a disorder with a startle response during periods of great fatigue.

Hyperekplexia is an extremely rare autosomal dominant neurological disease. The symptoms start in infancy with hypertonia, an abnormal muscle tension that decreases flexibility, and an exaggerated startle in all ages of life.

Patients are typically sent to therapy for BII phobia in order to receive therapeutic treatments to calm their levels of anxiety and stress. Therapists use a combination of psychological and physical measures, such as applying muscle tension, in order to help the patient to be aware that there is certainly a needle in front of them.

A popular method of treatment for BII phobics is Cognitive-Behavior Therapy (CBT), which is a technique that allows the patient to become immune to their fear by being exposed to it. For BII phobics, patients are given pictures of needles or blood, they are also asked to draw pictures of these needles and speak about it. Afterwards, they are given an actual needle, and the goal is: by that point, that the patient is to be comfortable enough with their fear of needles and blood.

Some patients may refuse professional help for their phobia. Instead, a different type of treatment solely revolves around motivation and whether or not the patient is willing to undergo through treating their phobia with self-help. Similar to CBT, patients treat themselves by completing exercises to become immune to their fear. This requires no professional assistance and merely relies on the person.

Research on hypnotherapy has been looked upon to treat patients with BII phobia. Hypnotherapists are known for using relaxing therapies towards individuals with common anxiety issues. A form of therapy given to patients with BII phobia include the “Applied Tension” method, which was developed by Lars-Göran Öst and his colleagues at the University of Uppsala in Sweden. This “coping method involves creating tension on a person’s arms, legs, and chest until they start to feel their body temperature rising,” (Robertson) which usually occurs within 10 to 20 seconds. These sessions of muscle tension is repeated 5 times with 20 to 30 second breaks. Patients should complete this form of therapy over the course of 5 weeks. This helps to prevent the patient from fainting by applying tension to the body, the blood pressure steadily rises, preventing any sudden drop until their vaccination is complete. By using this treatment, there was a noticeable improvement by 90% of patients with BII phobia. Compared to patients that only used the relaxation methods, where only 60% showed noticeable improvement.

Along with muscle tension,there are several methods of physical maneuvers that can help with the treatment of BII phobia. Therapists suggest that while being injected, patients should perform movements, such as: leg crossing, muscle tensing, and holding in the breath. Patients are instructed by their therapist to perform these maneuvers simultaneously while being injected with a needle. It’s also recommended that the patient stays seated with their head lowered while performing these movements.
