Is adiposity associated with back and lower limb pain? A systematic review.

Background: Back and lower limb pain have a major impact on physical function and quality of life. While obesity is a modifiable risk factor for musculoskeletal pain, the role of adiposity is less clear. This systematic review aimed to examine the relationship between both adiposity and its distribution and back and lower limb pain.

Association between hip muscle cross-sectional area and hip pain and function in individuals with mild-to-moderate hip osteoarthritis: a cross-sectional study.

Background: To examine the associations between hip muscle cross-sectional area and hip pain and function in community-based individuals with mild-to-moderate hip osteoarthritis.

Methods: This study included 27 participants with mild-to-moderate hip osteoarthritis. Cross-sectional area of hip muscles, including psoas major, rectus femoris, gluteus maximus, gluteus medius and minimus, adductor longus and magnus, obturator internus, and obturator externus, were measured from magnetic resonance images.

Are the size and composition of the paraspinal muscles associated with low back pain? A systematic review.

Background Context: Although previous studies have investigated the association between paraspinal muscle morphology and low back pain (LBP), the results are conflicting.

Purpose: This systematic review examined the relationship between size and composition of the paraspinal muscles and LBP.

Study Design/setting: A systematic review was carried out.
