Imbalanced joint load distribution across the tibiofemoral surface is a risk factor for osteoarthritic changes to this joint. Lateral wedge insoles, with and without arch support, are a form of biomechanical intervention that can redistribute tibiofemoral joint load, as estimated by external measures of knee load. The objective of this study was to examine the effect of these insoles on the internal joint contact characteristics of osteoarthritic knees during weightbearing.

Methods: This was an unblinded, 2-arm, delayed control, randomized pilot trial (NCT04683913).

Background: Running is a popular sport with widely recognized health benefits. Given the high rates of knee injury in runners and the growing prevalence of knee osteoarthritis (KOA), it may be useful to assess perceptions about running and knee joint health.
Purpose: The objectives of this study were to (1) explore and compare the perceptions of the general public (PUB) and health care professionals (HCPs) on the topic of running and knee health and (2) explore recommendations about running and knee health provided by HCPs.
The objective of this study was to compare the immediate effects of modifications to footwear or cadence on lower limb biomechanics of female Masters runners. After analyzing habitual treadmill running biomechanics in 20 female runners (52.4 [8.

- Inertial measurement units (IMUs) are devices used to measure various aspects of walking gait, and this study aimed to systematically review and analyze their validity and reliability in healthy adults during level walking.
- Researchers conducted searches across five databases, screening 82 articles to evaluate the quality and collect data on over 100 biomechanical outcomes.
- The findings indicated that IMUs demonstrated excellent validity and reliability for measuring step and stride times, with good reliability for other metrics like length and timing, while showing less consistent results for variability and symmetry in gait parameters.
