ABSTRACT
Background: Lateral epicondylitis is an overuse injury of the tendon and involving the extensor muscle of forearm. Induced pain at the upper trapezius (UT) produces an increase in wrist extensor electromyographic activity (EMG) which could potentially lead to overuse injury, such as LE, at the elbow. Some studies found that there is a relation between scapular muscle muscle performance and lateral epicondylitis and loss of grip strength in lateral epicondylitis. There is a lack of literature of similar studies among computer operators. The most common wrong working posture in computer operator is excessive wrist extension it causes to the overuse injury like lateral epicondylitis. The context and purpose of the study: To find out the relationship between scapular muscle performance and grip strength in lateral epicondylitis among computer operators. Result: The correlation between scapular muscle performance and grip strength in LE among computer operators was done using Karl Person correlation coefficient. The result indicated that there is a significant relation between scapular muscle performance and grip strength in lateral epicondylitis. Conclusion: The study showed that there is an impairment of scapular muscle performance and grip strength in lateral epcondylitis among computer operators. Implication: Regular physical activity and proper ergonomics advice can improve quality of life among computer operators.
