ObjectivesThe character of upper limb disorders in computer operators is subject to debate. While nerve involvement is suggested by the presenceof pain, paresthesia and subjective weakness, these symptoms are mainly interpreted as related to pathologies outside the nervous system. Findings in a previous study involving computer operators indicated peripheral nerve afflictions with specific locations in symptomatic subjects. Based on the same sample, this study addresses the relation of non-neurogenic findings to pain and neurological findings.Material and MethodsOverall, 96 computer operators scored their perceived pain in the neck, shoulder, elbow, and wrist/hand on a Visual Analogue Scale of 0–9. They underwent 2 sets of blinded physical examinations of selected non-neurogenic and neurological items, respectively. The authors analyzed correlations between the scores of each non-neuropathic finding, and a) mean pain scores for each and all regions, and b) scores for neurological patterns reflecting brachial plexopathy, median neuropathy (the elbow), and posterior interosseous neuropathy, respectively, and their combination. Kendall’s rank correlation test was applied for all statistical analyses.ResultsA median pain level of 1 or 0.5 was reported by 80 and 57 participants on the mouse-operating or contralateral side, respectively. Non-neurogenic and neurological findings were frequent. The mean overall pain correlated with palpation soreness of the neck insertions, and of the trapezius and supraspinatus muscles. Neck and elbow pain correlated with palpation soreness at the neck insertions and the lateral epicondyles, respectively. Significant correlations on the mouse-operating side were identified between posterior interosseous neuropathy and lateral epicondyle soreness, and between median neuropathy and any neurological pattern, and trapezius and lateral epicondyle soreness. Conclusions Pain correlated with palpation soreness, which again correlated with the neurological patterns. Palpation soreness may be less significant as a marker of a painful disorder as it correlated no better with regional than with overall pain. The physical examination of computer operators should include a sufficient neurological assessment.
