摘要: Pushing and pulling are common occupational exertions that increasingly associated with musculoskeletal complaints. This study focuses on the sensitivity of shoulder capacity to gender, handle height, exertion type (push or pull) orientation for these tasks. All factors except influenced unilateral total manual force strength (p < 0.01), being most influential. Interaction effects also existed between height type. Additionally, joint moments at shoulders low back were by all studied again Knowledge relative influence multiple can provide guidance regarding when designing evaluating pushing tasks a diverse population. Practitioner Summary: comprise nearly half materials handling Practitioners often assess, design modify while incorporating constraints, including direction interface. provides aid in context physical capacity.
