introduction: knee joint has the highest percentage of injuries among lower extremity joints especially in athletes and people with high activity levels. therefore, analyzing of knee movements has an important area of research in the bioengineering and rehabilitation fields. sharif human movement instrumentation system (sharif-hmis) is a new inertial sensor designed for movement analysis. the p...

BACKGROUND Clinical observation of aberrant movement patterns during active forward bending is one criterion used to identify patients with non-specific low back pain suspected to have movement coordination impairment. The purpose of this study was to describe and quantify kinematic patterns of the pelvis and trunk using a dynamics systems approach, and determine agreement between clinical obse...

In this paper, we present a novel visualization approach for the quantitative analysis of knee movement patterns in time-varying data sets. The presented approach has been developed for the analysis of patello-femoral instability, which is a common knee problem, caused by the abnormal movement of the patella (kneecap). Currently, patello-femoral analysis is based on acquisitions performed durin...

This study provided a quantitative analysis of the kinematic deviances in dysarthria associated with spastic cerebral palsy. Of particular interest were tongue tip movements during alveolar consonant release. Our analysis based on EMA measures indicated that speakers with spastic dysarthria had a restricted range of articulation and disturbances in articulatory-voicing coordination. The degree ...

This retrospective case series included five patients who underwent surgical resection of the cervical anterior osteophyte due to dysphagia. Videofluoroscopic swallowing studies (VFSSs) were performed before and after surgery on each patient, and kinematic analysis of the video clips from the VFSS of a 5-mL liquid barium swallow was carried out. Functional oral intake improved after surgery in ...

conclusions zebris movement analysis system is a highly reliable instrument for the measurement of gait parameters at different speeds in healthy athletes and those after acl reconstruction surgery. this implies its use in the assessment and treatment process of gait deficits in such a clinically important population. background reconstruction surgery is one of the treatment methods after an an...

Stroke, as a major risk factor for chronic impairment of upper limb function, can severely restrict the activities of daily living. Recently, robotic devices have been used to enhance the functional upper extremity movement of stroke patients. The purpose of the current study was to assess whether a robot-assisted reach training program using a whole arm manipulator (WAM) could improve upper ex...

Abstract– Different from the traditional rigid robots made by hard material such as metal, continuum robots are bionic mechanisms which feature high compliance and continuous shapechanging ability. A full compliant continuum robotic finger is proposed, which is driven by the compressed air inside its silicon rubber chamber and has a certain degree of grasping rigidity. By the moment equilibrium...
