PURPOSE OF REVIEW Patients with rheumatoid arthritis benefit from long-term moderate or high-intensity exercises. Moderate or high-intensity exercises were found to improve aerobic capacity, muscle strength, functional ability, and psychological well-being, and slow the age-related and sex-related decrease in bone mineral density of the hip. Despite these positive findings, there is also concer...

BACKGROUND AND PURPOSE It is unknown whether hemiparetic individuals are aware of their weight-bearing asymmetry during sit-to-stand tasks. This study compared the error between hemiparetic and healthy individuals' perception of weight-bearing and their actual weight-bearing distribution during the sit-to-stand task and analyzed the association between the knee extensor muscle strength and the ...

Patellar maltracking is thought to be one source of patellofemoral pain. Measurements of patellar tracking are frequently obtained during non-weight-bearing knee extension; however, pain typically arises during highly loaded activities, such as squatting, stair climbing, and running. It is unclear whether patellofemoral joint kinematics during lightly loaded tasks replicate patellofemoral joint...

BACKGROUND Weight-bearing radiographs are a critical component of evaluating foot and ankle pathology. An underlying assumption is that patients are placing 50% of their body weight on the affected foot during image acquisition. The accuracy of weight bearing during radiographs is unknown and, presumably, variable, which may result in uncertain ability of the resultant radiographs to appropriat...

OBJECTIVE To determine whether patients can accurately replicate and retain weight-bearing restrictions in both stationary (static) and dynamic conditions after autologous chondrocyte implantation (ACI). DESIGN Case series. SETTING Rehabilitation clinic. PARTICIPANTS A consecutive sample of patients (N=48) who had undergone ACI to a medial or lateral femoral condylar defect in the knee. ...
