The most-often prescribed treatments for early-stage RSIs include analgesics, myofeedback, biofeedback, physical therapy, relaxation, and ultrasound therapy. Low-grade RSIs can sometimes resolve themselves if treatments begin shortly after the onset of symptoms. However, some RSIs may require more aggressive intervention including surgery and can persist for years.

General exercise has been shown to decrease the risk of developing RSI. Doctors sometimes recommend that RSI sufferers engage in specific strengthening exercises, for example to improve sitting posture, reduce excessive kyphosis, and potentially thoracic outlet syndrome. Modifications of posture and arm use (human factors and ergonomics) are often recommended.

One way to prevent this injury from occurring is to be informed and educated about the risks involved in hurting your wrist and hand. If patients do suffer from median nerve palsy, occupational therapy or wearing a splint can help reduce the pain and further damage. Wearing a dynamic splint, which pulls the thumb into opposition, will help prevent an excess in deformity. This splint can also assist in function and help the fingers flex towards the thumb. Stretching and the use of C-splints can also assist in prevention of further damage and deformity. These two methods can help in the degree of movement the thumb can have. While it is impossible to prevent trauma to your arms and wrist, patients can reduce the amount of compression by maintaining proper form during repetitive activities. Furthermore, strengthening and increasing flexibility reduces the risk of nerve compression.

Impingement syndrome is usually treated conservatively, but sometimes it is treated with arthroscopic surgery or open surgery. Conservative treatment includes rest, cessation of painful activity, and physical therapy. Physical therapy treatments would typically focus at maintaining range of movement, improving posture, strengthening shoulder muscles, and reduction of pain. Physical therapists may employ the following treatment techniques to improve pain and function: joint mobilization, interferential therapy, accupuncture, soft tissue therapy, therapeutic taping, rotator cuff strengthening, and education regarding the cause and mechanism of the condition. NSAIDs and ice packs may be used for pain relief.

Therapeutic injections of corticosteroid and local anaesthetic may be used for persistent impingement syndrome. The total number of injections is generally limited to three due to possible side effects from the corticosteroid. A recent systematic review of level one evidence, showed corticoestroid injections only give small and transient pain relief.

A number of surgical interventions are available, depending on the nature and location of the pathology. Surgery may be done arthroscopically or as open surgery. The impinging structures may be removed in surgery, and the subacromial space may be widened by resection of the distal clavicle and excision of osteophytes on the under-surface of the acromioclavicular joint. Damaged rotator cuff muscles can be surgically repaired.

Non-surgical treatment of radial tunnel syndrome includes rest, NSAID, therapy with modalities, work modification, ergonomic modification, injection if associated with lateral epicondylitis.

Patients whose conditions are more adapted to surgical intervention are those who do not respond to prolonged conservative treatment. The patient must have pain with resisted supination, positive middle finger test, positive electrodiagnostic findings, and pain relief after anesthetic injection into the radial tunnel. Based on 2002 data, surgical decompression leads to 60-70% good or excellent results.

Cubital tunnel syndrome may be prevented or reduced by maintaining good posture and proper use of the elbow and arms, such as wearing an arm splint while sleeping to maintain the arm is in a straight position instead of keeping the elbow tightly bent. A recent example of this is popularization of the concept of cell phone elbow.

Dead arm syndrome starts with repetitive motion and forces on the posterior capsule of the shoulder. The posterior capsule is a band of fibrous tissue that interconnects with tendons of the rotator cuff of the shoulder. Four muscles and their tendons make up the rotator cuff. They cover the outside of the shoulder to hold, protect and move the joint.

Overuse can lead to a buildup of tissue around the posterior capsule called hypertrophy. The next step is tightness of the posterior capsule called posterior capsular contracture. This type of problem reduces the amount the shoulder can rotate inwardly.

Over time, with enough force, a tear may develop in the labrum. The labrum is a rim of cartilage around the shoulder socket to help hold the head of the humerus (upper arm) in the joint. This condition is called a superior labrum anterior posterior (SLAP) lesion. The final outcome in all these steps is the dead arm phenomenon.

The shoulder is unstable and dislocation may come next. Dead arm syndrome will not go away on its own with rest—it must be treated. If there is a SLAP lesion, then surgery is needed to repair the problem. If the injury is caught before a SLAP tear, then physical therapy with stretching and exercise can restore it.

It is common among baseball pitchers as they age, and it can also occur with quarterbacks in football and handball players also as they age.

A mnemonic for the basic treatment principles of any musculoskeletal problems is PRICE: Protection, Rest, Ice, Compression, and Elevation:

- "Protection": Guard the shoulder to prevent further injury.

- "Rest": Reduce or stop using the injured area for 48 hours.

- "Ice": Put an ice pack on the injured area for 20 minutes at a time, 4 to 8 times per day. Use a cold pack, ice bag, or a plastic bag filled with crushed ice that has been wrapped in a towel.

- "Compression": Compress the area with bandages, such as an elastic wrap, to help stabilize the shoulder.

- "Elevation": Keep the injured area elevated above the level of the heart. Use a pillow to help elevate the injury.

If pain and stiffness persist, see a doctor.

According to the American Academy of Orthopaedic Surgeons (AAOS) visits to orthopedic specialists for shoulder pain has been rising since 1998 and in 2005 over 13 million patients sought medical care for shoulder pain, of which only 34% were related to injury.

People with diabetes mellitus are at higher risk for any kind of peripheral neuropathy, including ulnar nerve entrapments.

Cubital tunnel syndrome is more common in people who spend long periods of time with their elbows bent, such as when holding a telephone to the head. Flexing the elbow while the arm is pressed against a hard surface, such as leaning against the edge of a table, is a significant risk factor. The use of vibrating tools at work or other causes of repetitive activities increase the risk, including throwing a baseball.

Damage to or deformity of the elbow joint increases the risk of cubital tunnel syndrome. Additionally, people who have other nerve entrapments elsewhere in the arm and shoulder are at higher risk for ulnar nerve entrapment. There is some evidence that soft tissue compression of the nerve pathway in the shoulder by a bra strap over many years can cause symptoms of ulnar neuropathy, especially in very large-breasted women.

Failure to relieve the pressure can result in necrosis of tissue in that compartment, since capillary perfusion will fall leading to increasing oxygen deprivation of those tissues. This can cause Volkmann's contracture in affected limbs. As intercompartmental pressure rises during compartment syndrome, perfusion within the compartment is reduced leading to ischemia, which if left untreated, results in necrosis of nerves and muscles of the compartment (Shears, 2006). Rhabdomyolysis and subsequent renal failure are also possible complications.

Chronic compartment syndrome in the lower leg can be treated conservatively or surgically. Conservative treatment includes rest, anti-inflammatories, and manual decompression. Elevation of the affected limb in patients with compartment syndrome is contraindicated, as this leads to decreased vascular perfusion of the affected region. Ideally, the affected limb should be positioned at the level of the heart. The use of devices that apply external pressure to the area, such as splints, casts, and tight wound dressings, should be avoided. If symptoms persist after conservative treatment or if an individual does not wish to cease engaging in the physical activities which bring on symptoms, compartment syndrome can be treated by a surgery known as a fasciotomy. Surgery is the most effective treatment for compartment syndrome. Incisions are made in the affected muscle compartments so that they will decompress. This decompression will relieve the pressure on the venules and lymphatic vessels, and will increase bloodflow throughout the muscle. Left untreated, chronic compartment syndrome can develop into the acute syndrome and lead to permanent muscle and nerve damage.

A military study conducted in 2012 found that teaching individuals with lower leg chronic exertional compartment syndrome to change their running stride to a forefoot running technique abated symptoms. Follow up studies are needed to confirm the finding of this study.

Hyperbaric oxygen therapy has been suggested by case reports – though as of 2011 not proven in controlled randomized trials – to be an effective adjunctive therapy for crush injury, compartment syndrome, and other acute traumatic ischemias, by improving wound healing and reducing the need for repetitive surgery.

Workers in certain fields are at risk of repetitive strains. Most occupational injuries are musculoskeletal disorders, and many of these are caused by cumulative trauma rather than a single event. Miners and poultry workers, for example, must make repeated motions which can cause tendon, muscular, and skeletal injuries.

Conservative treatment for this joint is similar to treatments for other types of arthritis, including restricting activity, anti-inflammatory medications (or supplements), physical therapy, and occasionally cortisone shots. If the pain is severe, surgery may be an option. The most common surgical treatment, known as resection arthroplasty, involves cutting a very small portion off the clavicle end and letting scar tissue fill in its place. Some portions of the acromioclavicular ligament may still remain attached.

Despite its wasting and at times long-lasting effects, most cases resolve themselves and recovery is usually good in 18–24 months, depending on how old the person in question is. For instance, a six-year-old could have brachial neuritis for only around 6 months, but a person in their early fifties could have it for over 3 years.

In terms of the prognosis of ulnar neuropathy early decompression of the nerve sees a return to normal ability (function). which should be immediate.Severe cubital tunnel syndrome tends to have a faster recovery process in individuals below the age of 70, as opposed to those above such an age. Finally, revisional surgery for cubital tunnel syndrome does not result well for those individuals over 50 years of age.

Shoulder impingement syndrome, also called subacromial impingement, painful arc syndrome, supraspinatus syndrome, swimmer's shoulder, and thrower's shoulder, is a clinical syndrome which occurs when the tendons of the rotator cuff muscles become irritated and inflamed as they pass through the subacromial space, the passage beneath the acromion. This can result in pain, weakness and loss of movement at the shoulder.

Depending on the severity of the lesion, physicians may recommend either conservative treatment or surgery. The first step is simply to rest and modify daily activities that aggravate the symptoms. Patients may be prescribed anti-inflammatory drugs, Physical or Occupational therapy, splints for the elbow and wrists, and corticosteroid injections as well. This is the most common treatment for CTS. Especially involving compression at the wrist, such as in CTS, it is possible to recover without treatment. Physical therapy can help build muscle strength and braces or splints help recover. In pronator teres syndrome, specifically, immobilization of the elbow and mobility exercise within a pain-free range are initially prescribed. However, if the patient is not relieved of symptoms after a usual 2 to 3 month refractory period, then decompression surgery may be required. Surgery involves excising the tissue or removing parts of the bone compressing the nerve.

Many tendon transfers have been shown to restore opposition to the thumb and provide thumb and finger flexion. In order to have optimal results the individual needs to follow the following principles of tendon transfer: normal tissue equilibrium, movable joints, and a scar-free bed. If these requirements are met then certain factors need to be considered such as matching up the lost muscle mass, fiber length, and cross-sectional area and then pick out muscle-tendon units of similar size, strength, and potential excursion.

For patients with low median nerve palsy, it has been shown that the flexor digitorum superficialis of the long and ring fingers or the wrist extensors best approximate the force and motion that is required to restore full thumb opposition and strength. This type of transfer is the preferred method for median nerve palsy when both strength and motion are required. In situations when only thumb mobility is desired, the extensor indicis proprius is an ideal transfer.

For high median nerve palsy, the brachioradialis or the extensor carpi radialis longus transfer is more appropriate to restore lost thumb flexion and side-to-side transfer of the flexor digitorum profundus of the index finger are generally sufficient. To restore independent flexion of the index finger could be performed by using the pronator teres or extensor carpi radialis ulnaris tendon muscle units. All of the mentioned transfers are generally quite successful because they combine a proper direction of action, pulley location, and tendon insertion.

Treatment for ulnar neuropathy can entail:

NSAID (non-steroidal anti-inflammatory) medicines. there is also the option of cortisone. Another possible option is splinting, to secure elbow, a conservative procedure endorsed by some. In cases where surgery is needed, cubital tunnel release, where the ligament of the cubital tunnel is cut, thereby alleviating pressure on nerve can be performed.

Treatment for the common occurrence of ulnar neuropathy resulting from overuse, with no fractures or structural abnormalities, is treatment massage, ice, and anti-inflammatories. Specifically, deep tissue massage to the triceps, myofascial release for the upper arm connective tissue, and cross-fiber friction to the triceps tendon.

Radial Tunnel Syndrome is caused by increased pressure on the radial nerve as it travels from the upper arm (the brachial plexus) to the hand and wrist.

The differential focuses on distinguishing it from similar entities such as quadrilateral space syndrome, which involves the teres minor and variably the deltoid, and suprascapular nerve impingement at the spinoglenoid notch, which predominantly involves the infraspinatus.

If the diver has not been exposed to excessive depth and decompression and presents as DON, there may be a predisposition for the condition. Diving should be restricted to shallow depths. Divers who have suffered from DON are at increased risk of future fracture of a juxta-articular lesion during a dive, and may face complications with future joint replacements. Because of the young age of the population normally affected, little data is available regarding joint replacement complications.

There is the potential for worsening of DON for any diving where there might be a need for decompression, experimental or helium diving. Physically stressful diving should probably be restricted, both in sport diving and work diving due to the possibility of unnecessary stress to the joint. Any diving should be less than 40 feet/12 meters. These risks are affected by the degree of disability and by the type of lesion (juxta-articular or shaft).

Evidence for the treatment of thoracic outlet syndrome as of 2014 is poor.

Prevention is a more successful strategy than treatment. By using the most conservative decompression schedule reasonably practicable, and by minimizing the number of major decompression exposures, the risk of DON may be reduced. Prompt treatment of any symptoms of decompression sickness (DCS) with recompression and hyperbaric oxygen also reduce the risk of subsequent DON.

Stretching, acupuncture, chiropractic adjustments, osteopathy, occupational and physical therapy are common non-invasive approaches used in the treatment of TOS. The goal of stretching is to relieve compression in the thoracic cavity, reduce blood vessel and nerve impingement, and realign the bones, muscles, ligaments, or tendons that are causing the problem.

- One commonly prescribed set of stretches includes moving the shoulders anteriorly (forward – called "hunching"), then back to a neutral position, then extending them posteriorly (backward, called "arching"), then back to neutral, followed by lifting the shoulders up as high as possible, and then back down to neutral, repeated in cycles as tolerated.

- Another set of stretches involves tilting and extending the neck opposite to the side of the injury while keeping the injured arm down or wrapped around the back.

- Occupational or Physical therapy can include passive or active range of motion exercises, working up to weighted or restricted sets (as tolerated).

- Physical therapy usually consists of mobilization of any or all of the articulations of the shoulder girdle, including the 1st rib, additional myofascial release (MFR) or Active Release Technique (ART) to the connected musculature, and use of passive or active range-of-motion exercises.

- Nerve gliding can be performed by extending the injured arm with fingers directly outwards to the side and tilting the head to both sides. A gentle pulling feeling is generally felt throughout the injured side. Initially, only do this and repeat. Once this exercise has been mastered and no extreme pain is felt, begin stretching your fingers back. Repeat with different variations, tilting your hand up, backwards, or downwards.

TOS is rapidly aggravated by poor posture. Active breathing exercises and ergonomic desk setup and motion practices can help maintain active posture. Often the muscles in the back become weak due to prolonged (years of) "hunching" and other poor postures.

Ice can be used to decrease inflammation of sore or injured muscles. Heat can also aid in relieving sore muscles by improving blood circulation to them. While the whole arm generally feels painful in TOS, some relief can be seen when ice or heat is intermittently applied to the thoracic region (collar bone, armpit, or shoulder blades).

Some babies recover on their own; however, some may require specialist intervention.

Neonatal/pediatric neurosurgery is often required for avulsion fracture repair. Lesions may heal over time and function return. Physiotherapeutic care is often required to regain muscle usage.

Although range of motion is recovered in many children under one year in age, individuals who have not yet healed after this point will rarely gain full function in their arm and may develop arthritis.

The three most common treatments for Erb's Palsy are: Nerve transfers (usually from the opposite arm or limb), Sub Scapularis releases and Latissimus Dorsi Tendon Transfers.

Nerve transfers are usually performed on babies under the age of 9 months since the fast development of younger babies increases the effectiveness of the procedure. They are not usually carried out on patients older than this because when the procedure is done on older infants, more harm than good is done and can result in nerve damage in the area where the nerves were taken from. Scarring can vary from faint scars along the lines of the neck to full "T" shapes across the whole shoulder depending on the training of the surgeon and the nature of the transplant.

Subscapularis releases, however, are not time limited. Since it is merely cutting a "Z" shape into the subscapularis muscle to provide stretch within the arm, it can be carried out at almost any age and can be carried out repeatedly on the same arm; however, this will compromise the integrity of the muscle.

Latissimus Dorsi Tendon Transfers involve cutting the Latissimus Dorsi in half horizontally in order to 'pull' part of the muscle around and attach it to the outside of the biceps. This procedure provides external rotation with varying degrees of success. A side effect may be increased sensitivity of the part of the biceps where the muscle will now lie, since the Latissimus Dorsi has roughly twice the number of nerve endings per square inch of other muscles.

Beals syndrome (congenital contractural arachnodactyly, Beals–Hecht syndrome) is a rare congenital connective tissue disorder. Beals syndrome has only recently been described as a syndrome distinct from Marfan's syndrome. Ricky Berwick is an internet star with this disease.

It was characterized in 1972.

It is associated with FBN2.

It is caused by a mutation in FBN2 gene on chromosome 5q23. Contractures of varying degrees at birth, mainly involving the large joints, are present in all affected children. Elbows, knees and fingers are most commonly involved. The contractures may be mild and tend to reduce in severity, but residual camptodactyly always remains present. The arm span exceeds body height but the discrepancy may be underestimated due to contractures of elbows and fingers. The same holds for the lower body portion with knee contractures. The most serious complication in CCA is scoliosis and sometimes kyphoscoliosis mandating surgery.
