Effects of the Computer Desk Level on the Musculoskeletal Discomfort of Neck and Upper Extremities and EMG Activities in Patients with Spinal Cord Injuries

摘要: Background. Computers are used as a means of social communication, for work and other purposes. However, patients with spinal cord injuries may have higher risk than normal individuals musculoskeletal problems when using computers owing to their inability control respective postures due in motor sensory functioning. Objectives. This study is aimed at identifying the effect computer desk heights on discomforts neck upper extremities EMG activities (C6) thoracic injuries. Methods. Participants present were diagnosed ASIA A or B. The divided into two groups according injuries: C6 group T2-T6 group. level was set 5 cm below elbow, elbow level, above level. Electromyography measure duration typing task EMG(%RVC) cervical erector spinae, trapezius, anterior deltoid, wrist extensor. Subjective discomfort (Borg-RPE) measured end experiment. Results. showed differences terms RPE corresponding each ( ). Postanalysis revealed had decreased increased, whereas subjects values accordance decreasing In EMG, both no significant interaction between muscles groups, interactions trapezius extensor found Conclusion. meaningful that it confirms posture preference cord-injured individuals.
