Relationship Between Scapular Muscle Performance And Grip Strength In Lateral Epicondylitis Among Computer Operators

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.

Comparison Of Neck Muscle Flexibility, Strength, Endurance And Proprioception Among The Video Display Terminal User’s In College Students With Neck Pain And Without Neck Pain

Background: Neck pain is one of the main causes of those who use video display terminal devices. Prolonged period of work in an awkward posture would mainly lead to neck pain among the VDT users. Studies show the prevalence of neck pain among VDT users as 45.5%. It is essential to identify factors for preventing people from getting neck pain. Studies show that musculoskeletal disorders are related to physical fitness level. Many factors in physical fitness can predict the incident of musculoskeletal disorders. There are still studies which are specific to neck pain and physical fitness in office workers. The context and purpose of the study: The main aim of the study is to compare the flexibility, strength, endurance and proprioception of neck among the VDT users in college students with neck pain and without neck pain. Results: The main finding of this study was that the video display terminal device users who use more than 4 hours / day have significantly lower flexibility, endurance and proprioception among student with neck pain compared to without pain VDT devices students. But there is no significant difference in strength among both groups. Conclusion: The majority of VDT user’s students who have neck pain are more affected in range of motion, endurance and proprioception compare to without neck pain. But there is no significant difference in strength among both groups. Implication: static posture without taking break in student who use VDT devices can be decrease in physical fitness of neck, so student are take break in between time to time and stretch their leg as well as arm ,neck.
