MRI of weight bearing and movement

Weight-bearing MRI of patellofemoral joint cartilage contact area.

PURPOSE To measure contact area of cartilage in the patellofemoral joint during weight bearing using an open MRI scanner. MATERIALS AND METHODS We developed an MR-compatible back support that allows three-dimensional imaging of the patellofemoral cartilage under physiologic weight-bearing conditions with negligible motion artifact in an open MRI scanner. To measure contact areas, we trained o...

Relationship between balance and maximum strength in weight-bearing and non-weight-bearing closed kinetic chain exercises

Balance and strength are important abilities that athletes should have them. This study was designed to investigate the relationship between maximum leg press (non-weight bearing closed kinetic chain) and squat (weight bearing closed kinetic chain) strength with statistic and dynamic balance. Thirty (15 men and 15 women) physically active participants (age, 22.13 ± 1.54 years; height, 171.26 ± ...

Magic angle artifact in MRI of the patellar ligament: preliminary comparison between conventional and weight- bearing MRI

effect of modified constraint induced movement therapy on weight bearing and protective extension in children with hemiplegic cerebral palsy

background: constraint induced movement therapy is one of the new therapeutic interventions that limits the performance of intact upper limb with increased use of the affected limb. aim of this study was to investigate the effects of  modified constraint induced movement therapy on weight bearing & protective extension in children with hemiplegic cerebral palsy. methods: 21 hemiplegic children ...

Effects of weight bearing and non-weight bearing exercises on bone properties using calcaneal quantitative ultrasound.

OBJECTIVE This study was designed to investigate bone properties using heel quantitative ultrasound (QUS) in young adults participating in various sports. METHODS A cross sectional study was performed on Chinese male students (n = 55), aged 18-22 years. Subjects with previous fractures or suffering from any diseases known to affect bone metabolism or taking any medication with such an effect,...
