Quantifying muscle mass is an essential part of physical therapy assessment, particularly in older adults and in people with chronic conditions associated with muscle atrophy. The purposes of this study were to examine the relationship between muscle cross-sectional area (CSA) and volume by use of magnetic resonance imaging (MRI) and to compare anthropometric estimations of midthigh CSA with measurements obtained from MRI. ⋯ Muscle CSA measured from a single slice provides a good indication of volume, but the most representative slice should be chosen on the basis of the muscle group of interest. Thigh circumference is not correlated with muscle volume and, therefore, should not be used as an indicator of muscle size. The development of population-specific reference equations for estimating muscle CSA from anthropometric measurements is warranted.

This study, using an evaluative, cross-sectional design, explored the self-efficacy, knowledge, and attitudes of health care providers who treat people with spinal cord injury (SCI) who may be gay, lesbian, bisexual, or transgender (GLBT). The study also designed and implemented a diversity training program and measured its effect on participants' perceptions of their ability to change their knowledge levels, attitudes, and self-efficacy with regard to sexual orientation diversity. ⋯ Health care providers who treat people with SCI self-report low levels of knowledge, tolerance versus respect, and low levels of self-efficacy with regard to sexual orientation diversity. If a health care provider has a low level of knowledge, tolerance versus respect, and a low level of diversity self-efficacy toward others, there may be direct physical and mental health consequences for the patient. A limitation of the study was that social desirability bias may have increased the number of participants who reported increased levels of self-efficacy following the videotape. Further research is recommended (1) to determine whether current diversity training for health care professionals includes diversity of sexual orientation and (2) to examine the knowledge levels, attitudes, and self-efficacy of health care professionals with regard to sexual orientation diversity while attempting to control for social desirability bias in participants' responses.

Randomized Controlled Trial Comparative Study
Hydrotherapy versus conventional land-based exercise for the management of patients with osteoarthritis of the knee: a randomized clinical trial.
This study was designed to evaluate the effectiveness of hydrotherapy in subjects with osteoarthritis (OA) of the knee compared with subjects with OA of the knee who performed land-based exercises. ⋯ Both water-based and land-based exercises reduced knee pain and increased knee function in participants with OA of the knee. Hydrotherapy was superior to land-based exercise in relieving pain before and after walking during the last follow-up. Water-based exercises are a suitable and effective alternative for the management of OA of the knee.

Posterior-anterior (PA) assessment of the lumbar spine correlates with radiographic signs of instability and can guide treatment choices, yet studies of the validity of lumbar PA assessments have not been conducted in vivo. The purposes of this study were to determine the intertester reliability of the PA examination in assessing intersegmental lumbar spine motion and to evaluate the validity of this procedure in vivo with dynamic magnetic resonance imaging (MRI). ⋯ Despite good intertester reliability for identifying the least mobile segment, PA assessments of lumbar segmental mobility did not agree with sagittal-plane motion measured by dynamic MRI. This finding calls into question the validity of the PA procedure for assessing intervertebral lumbar spine motion.

This case report describes a patient referred for physical therapy treatment of neck pain who had an underlying hangman's fracture that precluded physical therapy intervention. ⋯ In patients with neck pain caused by trauma, physical therapists should be alert for the presence of cervical spine fractures. Even if the initial radiographs are negative for a fracture, additional diagnostic imaging may be necessary for a small number of patients, because they may have undetected injuries that would necessitate medical referral and preclude physical therapy intervention.
