These include effort-based tests such as grip and pinch strength, diagnostic tests such as Finkelsteins test for De Quervains tendinitis, Phalens contortion, Tinels 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. Utilization of routine imaging  is useful in early detection and treatment of overuse injuries in at risk populations, which is important in preventing long term adverse effects. Treatment
There are no quick fixes for RSI. Early diagnosis is critical to limiting damage. For Upper Limb Repetitive Strain Injury (RSI), Occupational Therapists create interventions that include education to facilitate ergonomics. This will minimize the possibility of an upper limb strain injury by learning the correct approach during facilitating functional task movements. The RICE treatment is used as the first treatment for many muscle strains, ligament sprains, or other bruises and injuries. RICE is used immediately after an injury happens and for the first 24 to 48 hours after the injury. These modalities can help reduce the swelling and pain. Commonly 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.Although there are no "quick fixes" for RSI, there are effective approaches to its treatment and prevention.
Extreme temperatures have also been reported as risk factor for RSI. Risk factors
Occupational risk factors
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. Jobs that involve repeated motion patterns or prolonged posture within a work cycle, or both, may be repetitive. Young athletes are predisposed to RSIs due to an underdeveloped musculoskeletal system. Psychosocial factors
Factors such as personality differences to work-place organization problems. Certain workers may negatively perceive their work organization due to excessive work rate, long work hours, limited job control, and low social support. Previous studies shown elevated urinary catecholamines (stress-related chemicals) in workers with RSI. Pain related to RSI may evolve into chronic pain syndrome particularly for workers who do not have supports from co-workers and supervisors. Non-occupational factors
Age and gender are important risk factors for RSIs. The risk of RSI increases with age. Women are more likely affected than men because of their smaller frame, lower muscle mass and strength, and due to endocrine influences. In addition, lifestyle choices such as smoking and alcohol consumption are recognizable risk factors for RSI. Recent scientific findings indicate that obesity and diabetes may predispose an individual to RSIs by creating a chronic low grade inflammatory response that prevents the body from effectively healing damaged tissues. Diagnosis
RSIs are assessed using a number of objective clinical measures.
