ABSTRACT
OBJECTIVE: As many as 50% of patients diagnosed with obstructive sleep apnea stop adhering to the prescribed medical treatment of continuous positive airway pressure (CPAP) within 1-3 weeks of onset. Thus, a theory-based intervention using music to support habit formation was designed to improve CPAP adherence at onset. The intervention materials included directions for CPAP nightly use, a diary for recording nightly use and writing about CPAP benefits or problems. In addition, an audiotape with softly spoken instructions for placing the CPAP mask comfortably, using deep breathing and muscle relaxation along with the slowly decreasing music tempo was provided to listen to at bedtime each night. METHODS: Effects of this music intervention were tested in a randomized, placebo-controlled trial of 97 patients with 53 males (55%) and 44 females (45%). Moderate to severe apnea/hyponea scores (per sleep laboratory data) and medical diagnosis of OSA were required for study inclusion. RESULTS: Compared to placebo controls, a greater proportion of experimental patients were adhering (chi(2)=14.67, p<0.01; a large difference, Phi=0.39) at the end of the first month of CPAP onset. There were no differences in CPAP adherence at 3 (X(2)=0.065, p=0.79) and 6 (X(2)=.118, p=0.73) months. Patients' diary data and satisfaction survey results indicated the intervention was rated as helpful and guided formation of a relaxing, habitual routine of CPAP nightly use. CONCLUSION: The intervention had a strong effect for improving adherence to CPAP at 1 month. PRACTICE IMPLICATIONS: Adherence at the onset of treatment is critical and the audio music intervention was easily administered. Other interventions that target problems interfering with longer-term CPAP adherence are needed.

This study evaluated the feasibility, safety, and findings from a protocol for exercise-bicycle ergometry in subacute-stroke survivors. Of 117 eligible candidates, 14 could not perform the test and 3 discontinued because of cardiac safety criteria. In the 100 completed tests, peak heart rate was 116 +/- 19.1 beats/min; peak VO(2) was 11.4 +/- 3.7 ml x kg x min(-1), peak METs were 3.3 +/- 0.91, exercise duration was 5.1 +/- 2.84 min, and Borg score was 14 +/- 2.6. Among 71 tests, anaerobic threshold was achieved in 3.0 +/- 1.7 min with a VO(2) of 8.6 +/- 1.7 ml x kg x min(-1). After screening, this protocol is feasible and safe in subacute-stroke survivors with mild to moderate deficits. These stroke survivors have severely limited functional exercise capacity. Research and clinical practice in stroke rehabilitation should incorporate more comprehensive evaluation and treatment of endurance limitations.

STATEMENT OF PROBLEM: Distance walking remains compromised for many adults poststroke. The purpose of this study was to examine if the amelioration of stroke-related neuromuscular impairments, improved cardiovascular fitness, or better balance contributed to gains in distance walking. METHOD OF STUDY: The authors gathered baseline data of 92 adults at an average of 75 days poststroke and again 3 months later. Participants performed a bicycle ergometry stress test, a 6-min walk, and a Fugl-Meyer assessment for motor control, strength, and balance testing. The gain in walk distance was modeled using multiple regression with the variables of gains in peak VO2, lower limb control, plantar flexion strength, and balance. Separate analyses were done for poor performers, that is, participants who walked less than the median distance (213 m) at baseline and good performers, that is, participants who walked more than 213 m. RESULTS: For poor performers, the gain in balance was the only significant predictor of the gain in distance walking and accounted for 16% of the variance. For good performers, gains in peak VO2 and the lower limb Fugl-Meyer score were significant predictors and accounted for 28% of the variance. DISCUSSION: These results suggest that rehabilitation efforts to improve distance walking should focus on different factors depending on initial distance walked.
