Comparative Study
Validity and reliability of rectus femoris ultrasound measurements: Comparison of curved-array and linear-array transducers.
Muscle-mass loss augers increased morbidity and mortality in critically ill patients. Muscle-mass loss can be assessed by wide linear-array ultrasound transducers connected to cumbersome, expensive console units. Whether cheaper, hand-carried units equipped with curved-array transducers can be used as alternatives is unknown. ⋯ In the subjects with COPD, both reliability (ICC: 0.99) and repeatability (%TE: 7.6% and 9.8%) were high. Rectus area was related to quadriceps strength in COPD for both experienced operators (coefficient of determination: 0.67 and 0.70). In conclusion, measurements of rectus femoris cross-sectional area recorded with a curved-array transducer connected to a hand-carried unit are valid, reliable, and reproducible, leading us to contend that this technique is suitable for cross-sectional and longitudinal studies.

The study objective was to examine postacute changes in bowel and bladder continence and cognition after severe traumatic brain injury (TBI) in persons with long-term functional recovery to full independence. This case series included nine patients initially admitted to inpatient rehabilitation (IR) with severe TBI who had returned to prior responsibilities and functional independence by 8 to 15 mo. Patients had initial Glasgow Coma Scale scores of 3 to 6, posttraumatic amnesia durations of 18 to 70 d, time-to-follow-commands of 16 to 56 d, initial abnormal brain computed tomography scans, and initial pupil abnormalities. ⋯ All patients had combined IR discharge sphincter FIM scores that were 12 or greater, indicating independence to modified independence with bowel and bladder function with no incontinence. Five participants (55%) were admitted to IR with sphincter FIM scores of 11 to 12, indicating recovery of continence during acute care. These findings suggest potential usefulness of IR cognitive FIM score changes and of the recovery of bowel and bladder continence for predicting favorable functional outcomes following severe TBI.

The aim of this study was to examine the relationship between biopsychosocial functioning and pain severity and to evaluate whether pain self-efficacy (PSE) mediates this relationship. This study used archival data from a multidisciplinary pain management program. Participants were 99 individuals (69% female) with chronic low back pain who completed measures of biological, psychological, and social functioning, pain severity, and PSE at admission. ⋯ As we predicted, lower biological functioning (beta = -0.011; 95% confidence interval [CI] = -0.019 to -0.004, p = 0.002) and social functioning (beta = -0.009; 95% CI = -0.016 to -0.003, p = 0.007) were found to significantly predict higher pain severity, and lower social functioning was found to significantly predict lower PSE (beta = 0.196; 95% CI = -0.130 to 0.273, p = 0.002). PSE did not mediate the relationship between biopsychosocial functioning and pain severity, and psychological functioning did not significantly predict pain severity or PSE. These findings suggest that social functioning is an important factor in predicting outcomes and has a number of treatment implications.

Randomized Controlled Trial
Effects of hyperbaric oxygen on eye tracking abnormalities in males after mild traumatic brain injury.
The effects of hyperbaric oxygen (HBO2) on eye movement abnormalities in 60 military servicemembers with at least one mild traumatic brain injury (TBI) from combat were examined in a single-center, randomized, double-blind, sham-controlled, prospective study at the Naval Medicine Operational Training Center. During the 10 wk of the study, each subject was delivered a series of 40, once a day, hyperbaric chamber compressions at a pressure of 2.0 atmospheres absolute (ATA). ⋯ Between and within groups testing of pre- and postintervention means revealed no significant differences on eye movement abnormalities and no significant main effect for HBO2 at either 1.5 ATA or 2.0 ATA equivalent compared with the sham-control. This study demonstrated that neither 1.5 nor 2.0 ATA equivalent HBO2 had an effect on postconcussive eye movement abnormalities after mild TBI when compared with a sham-control.

Randomized Controlled Trial
Detraining outcomes with expiratory muscle strength training in Parkinson disease.
Expiratory muscle strength training (EMST) is efficacious for improving maximum expiratory pressure (MEP), cough function, and swallowing safety in Parkinson disease (PD). However, there are no published reports describing detraining effects following EMST in persons with PD. Moreover, there are no published reports describing detraining effects following any behavioral swallowing intervention. ⋯ No statistically significant changes were found in swallowing safety from post-EMST to postdetraining period. Following the 3 mo detraining period, seven participants demonstrated no change in swallowing safety, one worsened, and two had improvements. This preliminary study highlights the need for the design of maintenance programs to sustain function following intensive periods of training.
