Comparative Study
Aerobic capacity with hybrid FES rowing in spinal cord injury: comparison with arms-only exercise and preliminary findings with regular training.
To determine the magnitude and range of increases in peak aerobic capacity with hybrid-functional electrical stimulation (FES) rowing versus arms-only rowing in persons with spinal cord injury. ⋯ FES rowing may provide a more robust exercise stimulus for persons with spinal cord injury than most options currently available because of the greater aerobic demand.

Randomized Controlled Trial Comparative Study
Prolotherapy versus corticosteroid injections for the treatment of lateral epicondylosis: a randomized controlled trial.
To compare the efficacy of prolotherapy versus corticosteroid injection for the treatment of chronic lateral epicondylosis. ⋯ Both prolotherapy and corticosteroid therapy were generally well tolerated and appeared to provide benefit of long duration. Small sample size precludes determining whether one therapy is superior to the other. Larger, controlled trials appear feasible and warranted on the basis of these findings.

Randomized Controlled Trial
Ultrasound measurement of transversus abdominis during loaded, functional tasks in asymptomatic individuals: rater reliability.
To examine the ability of 2 clinicians to consistently measure recorded contractions of the transversus abdominis (TrA) muscle via ultrasound imaging (USI) during lifting and reaching tasks typical of everyday or work-related activities. ⋯ This study provides data for ensuring acceptable reliability of USI measures of TrA muscle thickness and thickness changes taken during loaded and functional activities. This study is the first to examine interrater and intrarater reliability of recorded cine loop images of asymptomatic adults in upright positions on 3 measures of TrA muscle activation (minimum, maximum, and percent change in muscle thickness). Reliable USI measures of TrA muscle thickness changes meet the ongoing need for clinicians' knowledge of proper and sufficiently adequate muscle activation in the clinical setting to assist progression of lumbar stabilization exercises.

To assess the bio-behavioral and physical performance characteristics of individuals with chronic low back pain who demonstrated the pain centralization phenomenon and received the McKenzie intervention using selected bio-behavioral and physical performance measures at intake and at 5 weeks and 10 weeks after treatment. ⋯ McKenzie intervention reduced pain and related fear and disability beliefs and improved physical performances in individuals with chronic low back pain. Improvements in physical performances remained stable 10 weeks after treatment, regardless of the elevation in bio-behavioral factors.
