BACKGROUND Accurate measurement of forces through the proximal radius can assess the effects of some surgical procedures on radioulnar load sharing, but is difficult to achieve given the redundant loading nature of the musculoskeletal system. Previously reported devices have relied on indirect measurements that may alter articular joint location and function. An axial load transducer interposed...

Purpose: Low back pain is one of the most common musculoskeletal disorders, and lifting is one of its risk factors. The activities of lumbar muscles as the main muscles involved in lifting are important with regard to identification of the allowable limits and the injury mechanisms as well as the motor control aspects. This study aimed to investigate the effects of the lifting speed on the lumb...

The chronic exposure of astronauts to microgravity results in structural degradation of their lower limb bones. Currently, no effective exercise countermeasure exists. On Earth, the impact loading that occurs with regular locomotion is associated with the maintenance of bone's structural integrity, but impact loads are rarely experienced in space. Accurately mimicking Earth-like impact loads in...

STUDY DESIGN In vivo laboratory studies were conducted to investigate the spine loads imposed on men and women during a series of lifting tasks that varied in the degree of lifting control required by the subject. OBJECTIVE To identify and understand differences in spine loading and musculoskeletal control strategies between men and women performing lifts of varying task complexity. SUMMARY...

Introduction: Manual handling of loads and carrying tasks widely exists in many occupations. Hospital staff because of Manual carrying of loads, are at increased risk of musculoskeletal disorders. Incorrect lifting methods, is an important risk factor for low back pain. The aim of this study was to analyze the biomechanical loads on the lumbar of nurses-aid in manual handling activities of seru...

Background and Objective: Activities and tasks of Manual Material Handling (includes lifting, carrying, lowering, pulling and pushing) are very common in work environments. The aim of this study was to determine the prevalence of musculoskeletal disorders and comparative evaluation of Manual Material Handling using of Snook Tables and NIOSH equation Methods in Stone cutting workshops. Material...

  Background and Aim: Casting workers are facing with ergonomics hazards such as overload in Manual Material Handling (MMH) tasks which expose them to risk of work-related musculoskeletal disorders (WMSDs). There are several methods to determine acceptable weight among which, Snook table is one of the oldest one. The aim of the study was to assess prevalence of WMSDs and to investigate MMH task...

QUESTION What is the point prevalence and 12-month prevalence of lower limb musculoskeletal pain in rural Tibet? Does this differ with gender or age? What factors that could contribute to lower limb musculoskeletal pain are commonly present? DESIGN Observational study using an investigator-administered questionnaire and observation walks through villages. PARTICIPANTS 499 people aged 15 yea...
