摘要: The purpose of this study was to investigate the strength and endurance deep neck flexor muscles in individuals with work-related pain. Subjects consisted two groups: twenty industrial workers pain age-matched healthy subjects. To evaluate cervical flexors, maximum voluntary contractile (MVCS) a sustained time at sub-maximal (SMVCS) (80% 50% MVCS) were measured using pressure biofeedback unit stop watch supine. MVCS 29.67±4.56 group 54.27±6.78mmHg normal group. 80% SMVCS 12.42±2.64 seconds 55.12±12.76 groups without 25.40±5.88 109.70±31.50 difference lower jaw position 16.75±3.57mm 23.03±2.51mm. MVCS, levels significantly greater than (p<0.05). findings indicate that maximal flexors decreased compared those Therefore, it is necessary include strengthening exercises therapeutic program musculoskeletal disorders involving
