Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

Arthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...

Circumferential film thickness measurement in journal bearings via the ultrasonic technique

Tribology International, 2020
A key parameter in hydrodynamic journal bearing performance is lubricant layer thickness around the circumference of the shaft-bearing interface. In the present work, the ultrasonic amplitude, phase change and resonant dip techniques are applied to ...
