Longitudinal evidence links joint level mechanics and muscle activation patterns to 3-year medial joint space narrowing.

Background: It is currently not known if there are different mechanical factors involved in accelerated rates of knee osteoarthritis structural progression. Data regarding the role of the transverse plane moment along with the contributions to joint loading from muscle activity, a primary contributor to the joint loading environment, is not well represented in the current literature on knee OA radiographic progression. The objective of this study was to understand if a 3-year end point corroborates what has been shown for longer term radiographic progression or provides more insight into factors that may be implicated in more accelerated radiographic progression than those shown previously.

Can altering motions, postures, and loads provide immediate low back pain relief: a study of 4 cases investigating spine load, posture, and stability.

Study Design: A quantitative biomechanical analysis of mechanism of pain alteration in 4 cases of low back pain.

Objective: To investigate the contributions of a number of biomechanical factors associated with pain alteration.

Summary Of Background Data: Some clinicians use mechanically based manual interventions in attempt to reduce low back pain.

Progressive hip rehabilitation: the effects of resistance band placement on gluteal activation during two common exercises.

Background: A critical issue for constructing a progressive rehabilitation program is the knowledge of muscle activation levels across exercises and within exercise modifications. Many exercises are offered to enhance gluteal muscle activation during functional rehabilitation but little data exists to guide the progression of exercise intensity during rehabilitation. The objective of this paper was to examine the effects of altering resistance band placement during 'Monster Walks' and 'Sumo Walks.
