Title Supermarket checker motions and cumulative trauma risk
Bibliographic information Aug. 1993, Vol.35, No.8, p.805-811. Illus. 16 ref.
Abstract The relationship between specific motions and symptoms consistent with upper extremity cumulative trauma disorders (UECTDs) was investigated in 50 supermarket checkers. Each completed a questionnaire concerning UECTD symptoms; each participant was videotaped while performing checking work. Relationships between an individual's motion indices and symptom indices were analyzed by determining the percent of subjects "positive" for symptoms in each quartile of motion index, by rank correlation, and by regression of symptom scores on principal components of motions. Trends toward relationship of wrist flexion and extension, lumbar flexion, and pronation with hand-wrist-lower arm and carpal tunnel syndrome were noted. Principal components regression confirmed that extension and flexion were related to these two symptom outcomes. This study suggests that postural loading can be determined on an individual basis in a meaningful fashion, that interventions that decrease such loading may be beneficial and that certain repetitive motions cause UECTD symptoms.
