OBJECTIVE The authors sought to use biomechanical measures, including motion and pressure, to compare four office chairs. BACKGROUND The fit of a person to a chair is related to the geometric and kinematic compatibility between the two. This geometric compatibility influences the motions that are allowed or prohibited and the support pressures at the body-chair interface. Thus, during evaluat...

This paper discusses the details of a study undertaken for biomechanical evaluation of a number of Manual Material Handling (MMH) tasks being carried out at a construction site in India. A comprehensive methodology involving a two dimensional dynamic biomechanical evaluation approach is developed for such construction MMH tasks involving carrying and lifting of materials like normal and Reinfor...

A simple measure of overall walking effort would be valuable to patients and clinicians to select suitable treatment interventions and to monitor progress. In this paper, the reproducibility and responsiveness of seven potentially useful clinical measures of walking effort are presented. These walking effort outcomes were derived from a compass gait model and space curve displacement, accelerat...

OBJECTIVE Lateral wedge insoles are a potential simple treatment for medial knee osteoarthritis (OA) patients by reducing the external knee adduction moment (EKAM). However in some patients, an increase in their EKAM is seen. Understanding the role of the ankle joint complex in the response to lateral wedge insoles is critical in understanding and potentially identifying why some patients respo...

Methods Young people aged between 8-14 were recruited from the rheumatology based Non-Inflammatory Musculoskeletal Pain Clinic at Great Ormond Street Hospital over a 12 month period. They were assessed using biomechanical measures (muscle strength and degree of hypermobility), sensory processing using Quantitative Sensory Testing and psychological measures of anxiety, depression and pain coping...

OBJECTIVES Short-distance household falls are a common occurrence in young children, but are also a common false history given by caretakers to conceal abusive trauma. The purpose of this study was to determine the severity of injuries that result from accidental short-distance household falls in children, and to investigate the association of fall environment and biomechanical measures with in...

PURPOSE Accurate assessment of toxicity allows for timely delivery of supportive measures during radiation therapy for head and neck cancer. The current paradigm requires weekly evaluation of patients by a provider. The purpose of this study is to evaluate the feasibility of monitoring patient reported symptoms via mobile devices. METHODS AND MATERIALS We developed a mobile application for pa...

This study describes a new custom measurement system designed to investigate the biomechanics of sitting-pivot wheelchair transfers and assesses the reliability of selected biomechanical variables. Variables assessed include horizontal and vertical reaction forces underneath both hands and three-dimensional trunk, shoulder, and elbow range of motion. We examined the reliability of these measure...
