Observational Study
Factors associated with paraspinal muscle asymmetry in size and composition in a general population sample of men.
Paraspinal muscle asymmetry in cross-sectional area (CSA) and composition have been associated with low back pain and pathology. However, substantial multifidus muscle asymmetry also has been reported in men who were asymptomatic, and little is known about other factors influencing asymmetry. ⋯ Few of the factors investigated were associated with paraspinal muscle asymmetry, and associations were inconsistent and modest, explaining little of the variance in paraspinal muscle asymmetry.

Multicenter Study
Participation following knee replacement: the MOST cohort study.
Participation is an important, yet seldom studied, outcome after total knee replacement (TKR). ⋯ Although there was a mean increase in participation ≥1 year following TKR, participation restriction was common. The likelihood of low participation was increased among women, non-whites, and those with depressive symptoms, severe pain in either knee, or worse pre-TKR function.

The original 20-item Upper Extremity Functional Index (UEFI) has not undergone Rasch validation. ⋯ Rasch analysis did not support the validity of the 20-item UEFI. However, the UEFI-15 was a valid and reliable interval-level measure of a single dimension: upper extremity function. Rasch analysis supports using the UEFI-15 in physical therapist practice to quantify upper extremity function in patients with musculoskeletal disorders of the upper extremity.
