Documenting female spine motion during coitus with a commentary on the implications for the low back pain patient.

Purpose: To describe female lumbar spine motion and posture characteristics during coitus and compare these characteristics across five common coital positions. Exacerbation of low back pain during coital movements and positions is a prevalent issue reported by female low back pain (LBP) patients. To address this problem, the first study to examine lumbar spine biomechanics during coitus was conducted.

Examining the effects of altering hip orientation on gluteus medius and tensor fascae latae interplay during common non-weight-bearing hip rehabilitation exercises.

Background: Improving activity and strength of the gluteus medius muscle is a common goal among clinicians aiming to rehabilitate lower extremity and low back injuries. The functional anatomy of the hip is complex, particularly how position-dependent the activity and strength of many muscles surrounding the hip are, and the optimal exercise technique to isolate gluteus medius remains controversial. The objective of this study was to quantify the effect of altering hip orientation during side-lying clamshell and hip abduction exercises on the relative muscle activation profiles of gluteus medius and tensor fascae latae.

Male spine motion during coitus: implications for the low back pain patient.

Study Design: Repeated measures design.

Objective: To describe male spine movement and posture characteristics during coitus and compare these characteristics across 5 common coital positions.

Summary Of Background Data: Exacerbation of pain during coitus due to coital movements and positions is a prevalent issue reported by low back pain patients.

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.
