OBJECTIVE To investigate the effects of dual task balance training in the elderly on standing postural control while performing a cognitive task. DESIGN A randomized two-group parallel controlled trial. PARTICIPANTS Forty-three subjects (all >65 years old) were enrolled in the study and were assigned randomly to either an experimental group (n = 21) or(More)
BACKGROUND The aim of this study was to investigate the kinetic characteristics of compensatory backward descending movement performed by patients with osteoarthritis of the knee. METHODS Using a three-dimensional motion analysis system, we investigated lower extremity joint angles, joint moments, joint force of the support leg in forward and backward(More)
The purpose of the present study is to analyze trunk-lower extremity muscle activities and trunk postural changes during the carriage of different backpacks. Nineteen male university students (21+/-3 years) participated in the experiment's four standing modes: (1) unloaded standing, (2) 10% body weight (BW) load (in the form of a backpack), (3) 15% BW load(More)
OBJECTIVE To investigate the relationship between errors in perceiving postural limits and falls in hospitalized hemiplegic patients and to determine whether this relationship is useful for identifying patients at high risk of falls. DESIGN Observational study. SUBJECTS Seventy-six hemiplegic patients who were admitted to a rehabilitation hospital. (More)
In this study, both a questionnaire survey and a functional assessment were performed. The results were examined to clarify factors which might influence clinical symptoms in patients with surgical repairs following complete rotator cuff tear. In addition, evidence on which to base postoperative activities of daily living and rehabilitation was elucidated.(More)
In general, surgery is recommended for calcificated tendinitis of the shoulder if the patients have symptoms after conservative treatments, including needle aspiration and physical therapy. Many researchers agree about the need for adequate physical therapy consisting of range of motion exercise, muscle strengthening exercises and electrophysical agents.(More)
To clarify the excitability of spinal motor neuron function after transcutaneous electrical stimulation (TES), we investigated the F-wave before and after TES. Fourteen healthy volunteers with a mean age of 23.4 years were studied. TES was applied to the flexor hallucis brevis (FHB) for 15 minutes. F-wave and M-wave were recorded from the FHB after tibial(More)
PURPOSE  The study focused on the falls efficacy of stroke survivors in the community and its association with the related factors. METHOD  The study was conducted through a cross-sectional design in the community setting. One hundred seven stroke survivors were recruited. Falls efficacy was measured by the 7-item Falls Efficacy Scale International(More)
We examine the evolution of the public electronic trading community over the Internet, based on the case study of two e-hubs for direct materials in the hi-tech industry in Asia. We identify three different stages in the transformation of the public online trading community. We also observe that there are two types of online trading community formation at a(More)
