The active control of the trunk plays an important role in frontal plane gait stability. We characterized response to different step widths using a novel feedback system and examined effects wide narrow as they each present unique task demands. Twenty healthy young adults walked on treadmill at 1.25 m/s five prescribed widths: 0.33, 1.67, 1, 1.33, 1.67 times preferred width. Motion capture was ...

background: to determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves.   methods: all adolescent idiopathic scoliosis (ais) patients included in the study were classified according to lenke and king classification. the fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt of t1 an...

in this article a new and an accurate method for kinematic and dynamic analysis of a parallel robot 3prs and a hybrid robot (parallel and serial) 3prs-rrp are presented, which is based on the denavit-hartenberg transformation matrix algebra. first, basic properties of various kinds of robots are compared, and then the denavit-hartenberg parameters and their table are introduced. next, the metho...

objectives: the aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how total knee replacement (tkr) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. methods: two-dimensional kinematic gait pattern of 10 participants were collected before and after the tkr surgery, using a ...

Since the contribution of lumbar multifidus(LM) is not well understood in relation to non-specific low back pain(LBP), this may limit physiotherapists choosing most appropriate treatment strategy. This study aims compare clinical characteristics, terms LM function and morphology, between subacute chronic LBP patients from a large practice cohort compared healthy controls. Multicenter case contr...

Joint range of motion and physical capacities have been shown to change with age in both throwing athletes and non-athletes. The age of professional baseball pitchers could span from late teens to mid-40s. However, the effects of age on the pitching kinematics among professional baseball pitchers are still unknown. In this study, 67 healthy professional baseball pitchers were tested using a 3D ...
