The purpose of our study is to investigate whether there is an age-related change in T1 rho values and to evaluate the effects of weight bearing on age-related increase in T1 rho values of normal cartilage. Thirty-two asymptomatic patients were examined using a 3.0T MRI to determine knee cartilage T1 rho values. Femorotibial and patella cartilage was defined as weight-bearing cartilage (WB-...

EFFECT OF BIOFEEDBACK DEVICES IN PARTIAL WEIGHT-BEARING ORTHOPAEDIC PATIENTS. Joshua W Hustedt, Michael R Baumgaertner, Michael P Leslie, Jonathan N Grauer. Department of Orthopaedics and Rehabilitation, Yale University School of Medicine, New Haven, CT. Partial weight-bearing (PWB) instructions are commonly given to orthopaedic patients. However, the ability of patients to comply with these in...

[Purpose] The purpose of this study was to access the effect of weight bearing exercise (treadmill exercise) and non-weight-bearing exercise (swimming exercise) on gait in the recovery process after a sciatic nerve crush injury. [Subjects and Methods] Rats were randomly divided into a swimming group (n=3) with non-weight-bearing exercise after a sciatic nerve crush and a treadmill group (n=3) w...

AIMS The analgesic effects of moxibustion on an experimental model of osteoarthritis of the knee were investigated. METHODS Male Wistar rats (n=36, 296-421 g) were used. Intra-articular injection of mono-iodoacetic acid (MIA) was performed to induce knee osteoarthritis. Indirect moxibustion was applied to the lateral aspect of the knee joint every other day for 28 days (14 treatments). Weight...

OBJECTIVE Although clinical reports have described medial meniscal subluxation (MMS) in knee OA, few controlled studies have used dynamic US to examine the potential impact of MMS on OA. The aim of this study was to assess MMS in patients with knee OA and in asymptomatic controls by US in different weight-bearing positions. METHODS In a cross-sectional controlled study, MMS was evaluated by U...

PURPOSE To determine the effectiveness and safety of interventions used for rehabilitation after open reduction and internal fixation of ankle fractures. METHODS A systematic review and meta-analysis was performed using both randomized trials and cohort studies. The effect of mobilization, weight-bearing, and unprotected weight-bearing as tolerated on postoperative recovery was compared using...

[Purpose] The aim of this study was to investigate the effects of an ankle foot orthosis on weight-bearing abilities of stroke patients by comparing weight loading during performance of tasks in various standing positions on the affected side. [Subjects and Methods] This study was performed with 16 stroke patients. To measure the weight loading value and percentage of weight loading in affected...

The role of satellite cells and DNA unit size in determining muscle size was examined by inhibiting postnatal skeletal muscle development by using hindlimb suspension. Satellite cell mitotic activity and DNA unit size were determined in the soleus muscles from hindlimb-suspended and age-matched weight-bearing rats before the initiation of hindlimb suspension, at the conclusion of a 28-day hindl...
