RSIs are assessed using a number of objective clinical measures. These include effort-based tests such as grip and pinch strength, diagnostic tests such as Finkelstein's test for De Quervain's tendinitis, Phalen's Contortion, Tinel's Percussion for carpal tunnel syndrome, and nerve conduction velocity tests that show nerve compression in the wrist. Various imaging techniques can also be used to show nerve compression such as x-ray for the wrist, and MRI for the thoracic outlet and cervico-brachial areas.

Although strains are not restricted to athletes and can happen while doing everyday tasks, however, people who play sports are more at risk for developing a strain. It should also be noted that it is common for an injury to develop when there is a sudden increase in duration, intensity, or frequency of an activity.

The diagnosis of mild back strain can be made with a medical history and physical examination. In case of more severe strains, an X-ray should be taken to rule out fracture and disc herniation. Back sprain is treated using analgesics such as ibuprofen, rest and use of ice packs. The patient can resume activities 24-48 hours after pain and swelling is reduced. It is not recommended to have prolonged immobilization or bed rest. If the pain does not subside in two weeks, additional treatment may be required.

Prevention of back strain is possible by adopting proper body mechanics while sitting, standing and lifting. Cessation of smoking, maintaining a healthy diet, exercise and normal weight is also good for preventing back strain.

The first-line treatment for a muscular strain in the acute phase include five steps commonly known as P.R.I.C.E.

- Protection: Apply soft padding to minimize impact with objects.

- Rest: Rest is necessary to accelerate healing and reduce the potential for re-injury.

- Ice: Apply ice to induce vasoconstriction, which will reduce blood flow to the site of injury. Never ice for more than 20 minutes at a time.

- Compression: Wrap the strained area with a soft-wrapped bandage to reduce further diapedesis and promote lymphatic drainage.

- Elevation: Keep the strained area as close to the level of the heart as is possible in order to promote venous blood return to the systemic circulation.

Immediate treatment is usually an adjunctive therapy of NSAID's and Cold compression therapy. Controlling the inflammation is critical to the healing process. Cold compression therapy acts to reduce swelling and pain by reducing leukocyte extravasation into the injured area. NSAID's such as Ibuprofen/paracetamol work to reduce the immediate inflammation by inhibiting Cox-1 & Cox-2 enzymes, which are the enzymes responsible for converting arachidonic acid into prostaglandin. However, NSAIDs, including aspirin and ibuprofen, affect platelet function (this is why they are known as "blood thinners") and should not be taken during the period when tissue is bleeding because they will tend to increase blood flow, inhibit clotting, and thereby increase bleeding and swelling. After the bleeding has stopped, NSAIDs can be used with some effectiveness to reduce inflammation and pain.

A new treatment for acute strains is the use of platelet rich plasma (PRP) injections which have been shown to accelerate recovery from non surgical muscular injuries.

It is recommended that the person injured should consult a medical provider if the injury is accompanied by severe pain, if the limb cannot be used, or if there is noticeable tenderness over an isolated spot. These can be signs of a broken or fractured bone, a sprain, or a complete muscle tear.

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.

In most cases, a physician will diagnose an ulnar collateral ligament injury using a patient’s medical history and a physical examination that includes a valgus stress test. The valgus stress test is performed on both arms and a positive test is indicated by pain on the affected arm that is not present on the uninvolved side. Physicians often utilize imaging techniques such as ultrasound, x-rays and magnetic resonance imaging or arthroscopic surgery to aid with making a proper diagnosis.

Laximetry is a reliable technique for diagnosing a torn anterior cruciate ligament.

The MRI is perhaps the most used technique for diagnosing the state of the Anterior Cruciate Ligament but it not always the most reliable. In some cases the Anterior Cruciate Ligament can indeed not be seen because of the blood surrounding it.

A side strain is a muscle strain caused by tearing of the transversalis fascia or the internal oblique muscle. When this occurs, stretching the muscle will be severely painful, making it difficult to move the arm, and the strain may later be marked by swelling or bruising.

The strain usually occurs due to the internal oblique muscle contracting suddenly from a stretched position. It may happen suddenly, or over time from regular repetitive activity. It is common in cricket players, and occurs on the opposite side of the arm that is used for bowling. The injury has also been reported in rowing, baseball and ice hockey. The preferred treatment for a side strain is regular rest and inactivity on the affected muscle. With appropriate rest, regular activity on the muscle can occur between 4 and 6 weeks, though it may take longer.

Segond and reverse Segond fractures are characterized by a small avulsion, or "chip", fragment of characteristic size that is best seen on plain radiography in the anterior-posterior plane. The chip of bone may be very difficult to see on the plain x-ray exam, and may be better seen on computed tomography. MRI may be useful for visualization of the associated bone marrow edema of the underlying tibial plateau on fat- saturated T2W and STIR images, as well as the associated findings of ligamentous and/or meniscal injury.

Ultrasound imaging can be used to evaluate tissue strain, as well as other mechanical properties.

Ultrasound-based techniques are becoming more popular because of its affordability, safety, and speed. Ultrasound can be used for imaging tissues, and the sound waves can also provide information about the mechanical state of the tissue.

Increased water content and disorganized collagen matrix in tendon lesions may be detected by ultrasonography or magnetic resonance imaging.

Back strain occurs more in women than men and is more common after pregnancy. Lean people, those standing for long hours and those doing sedentary work in bad posture are prone to back strain. Back strain is also more common in people with excessive curving of the back, weak muscles (as in muscular dystrophies) and tight thigh muscles. Sportspersons who play sports involving lifting heavy weights, pushing and pulling are also prone to back strain.

CMC OA is diagnosed based on clinical findings and radiologic imaging.

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.

Pain along the inside of the elbow is the main symptom of this condition. Throwing athletes report it occurs most often during the acceleration phase of throwing. Closing the hand and clenching the fist has also been shown to reproduce the painful symptoms. The injury is often associated with an experience of a sharp “pop” in the elbow, followed by pain during a single throw. In addition, swelling and bruising of the elbow, loss of elbow range of motion, and a sudden decrease in throwing velocity are all common symptoms of a UCL injury. If the injury is less severe, pain can be minimal with complete rest.

Rest, Ice, Compression and Elevation (RICE) are standard treatments in the first 48 hours of an injury to the hip pointer. After 48 hours, patients can begin gently stretching, strengthening exercises, flexibility and coordination. For the first 7–10 days, patients can take anti-inflammatories such as ibuprofen and apply ice. Since this injury is very painful, recovery is usually very slow. When the person is without pain, sports massage and range-of-motion activities may reduce tension and swelling and prevent scar tissue buildup. Furthermore, an injection of corticosteroids into the affected area may reduce symptoms in the short term and accelerate rehabilitation. Operative treatment is rarely indicated and is reserved for patients suffering from significant displacement or fractures of the bones.

To prevent hip pointer, the equipment must be adequate in the sport and be well positioned and good size. It should also maintain excellent flexibility, strength and endurance of the hip, pelvis and lower back muscles.

Because of the high rate of associated ligamentous and meniscal injury, the presence of a Segond or reverse Segond fracture requires that these other pathologies must be specifically ruled out. Increasingly, reconstruction of the ACL is combined with reconstruction of the ALL when this associated pathology is present. It is often associated with an increased 'pivot shift' on physical exam.

Percutaneous ultrasonic tenotomy provided continued pain relief and functional improvement for recalcitrant tennis elbow at a 3-year follow-up.

Knee MRIs should be avoided for knee pain without symptoms or effusion, unless there are non-successful results from a functional rehabilitation program.

About 25% of people over the age of 50 experience knee pain from degenerative knee diseases.

If the femur head is dislocated, it should be reduced as soon as possible, to prevent damage to its blood supply. This is preferably done under anaesthesia, following which, leg is kept pulled by applying traction to prevent joint from dislocating.

The final management depends on the size of the fragment(s), stability and congruence of the joint. In some cases traction for six to eight weeks may be the only treatment required; however, surgical fixation using screw(s) and plate(s) may be required if the injury is more complex. The latter treatment will be called for if bone fragments do not fall into place, or if they are found in the joint, or if the joint itself is unstable.

At the site of injury: After stabilizing an injured person and resuscitation, quick examination is done to check injury to vital organs.

If one suspects injury to the hip, it is imperative to immobilse the limb using some kind of support to prevent movements of the injured limb to prevent further damage

A trained paramedic may be able to diagnose hip dislocation by noticing the position of the injured limb. It is essential to document status of nerves and vessels before starting any treatment to protect oneself from litigation

On arrival at the hospital, trained trauma surgeon will assess the patient and prescribe necessary tests including x-rays as described earlier.

Non-surgical management consists of reducing the dislocated joint by maneuver under anaesthesia and applying traction to the limb to maintain position of joint and fractured bones. If non surgical management is preferred it may require six weeks to 3 months for recovery.

Management of shoulder dystocia has become a focus point for many obstetrical nursing units in North America. Courses such as the Canadian More-OB program encourage nursing units to do routine drills to prevent delays in delivery which adversely affect both mother and fetus. A common treatment mnemonic is ALARMER

- Ask for help. This involves preparing for the help of an obstetrician, for anesthesia, and for pediatrics for subsequent resuscitation of the infant that may be needed if the methods below fail.

- L hyperflexion (McRoberts' maneuver)

- Anterior shoulder disimpaction (pressure)

- Rubin maneuver

- M delivery of posterior arm

- Episiotomy

- Roll over on all fours

Typically the procedures are performed in the order listed above and the sequence ends whenever a technique is successful. Intentional clavicular fracture is a final attempt at nonoperative vaginal delivery prior to Zavanelli's maneuver or symphysiotomy, both of which are considered extraordinary treatment measures.

To assess an olecranon fracture, a careful skin exam is performed to ensure there is no open fracture. Then a complete neurological exam of the upper limb should be documented. Frontal and lateral X-ray views of the elbow are typically done to investigate the possibility of an olecranon fracture. A true lateral x-ray is essential to determine the fracture pattern, degree of displacement, comminution, and the degree of articular involvement.

Signs and symptoms include immediate pain, bruising and swelling, obvious weakness, spasms and a rapid decline in the hip / leg function, resulting in a decreased range of motion.
