studious mood objective: To determine if distractive auditory stimuli (DAS) in the form of music would further adherence to a walking regimen following completion of a pulmonary rehabilitation program (PRP) and, thereby, maintenance of gains achieved during the program.

Design: Experimental, randomized, two-group design with testing at baseline, 4 weeks, and 8 weeks.

Setting: Outpatient.

Patients: Twenty-four patients (4 men and 20 women) with moderate-to-severe COPD (FE[Vsub1] 413 [+ or -] 13% predicted [mean [+ or -] SD])

Intervention: Experimental cluster subjects (n = 12) were instructed to walk at their allow pace for 20 to 45 min, brace to five times a week, using DAS with a portable audiocassette player. The repress group (n = 12) received the same instructions, on the contrary no DAS.

Measurements and results: Primary consequence measures were perceived dyspnea during activities of daily living (ADL) and 6-min walk (6MW) distance. Secondary consequence measures were anxiety, depressive symptoms, health-related quality of life (QoL) global QoL and breathlessness and fatigue at completion of the 6MW In addition, all exposes recorded the distance and lime walked using self-report (pedometers and daily logs) There was a significant decrease in perceived dyspnea during ADL (p = 00004) and a significant increase in 6MW distance (p = 00004) above time in the DAS cluster compared to the control assign places to DAS subjects increased 6MW distance 445 [+ or -] 264 feet (mean [+ or -] SD) from baseline to 8 weeks, whereas hinder subjects decreased 6MW distance to 169 [+ or -] 154 feet No significant differences were noted for the remaining variables. The cumulative distance walked by means of the DAS group was 191 [+ or -] 167 miles compared to 154 [+ or -] 80 miles for the hinder group, a 24% difference (p = 049) Despite this difference, self-report exercise log data were similar for the pair groups.

Conclusion: make subordinates who used DAS while walking had improved functional performance and decreased perceptions of dyspnea, whereas reign over subjects could not maintain post-PRP gains. DAS is a simple, cost-effective strategy that may have the potential to augment the effectiveness of post-PRP maintenance training.

**********

Pulmonary rehabilitation programs (PRPs) have been shown to increase patient independence by means of instruction in symptom management and improve activity tolerance within use of exercise training, considered the "cornerstone" of pulmonary rehabilitation. Adherence to an appropriate regimen has repeatedly been shown to improve exercise tolerance, increase hardness and endurance, and reduce dyspnea in patients with COPD (1-4)

While as it was programs have been shown to induce short-term increases in exercise tolerance, these improvements are not sustained. (5) The inability to sustain an increase in exercise tolerance may, in part, ensue from increasing patient age and disease progression. In addition, long-term adherence to an exercise program is known to be poor in patients with COPD Short-term benefits are quickly wasted if exercise intensity and duration are not maintained. (6) These observations reinforce the ne for home-based programs, which criterion strategies to sustain gains achieved in PRP the same approach involves the use of behavioral interventions like as cognitive-behavioral approaches and desensitization including distraction in combination with exercise training. (7) Haas and colleagues (8) postulate that desensitization to dyspnea can be accomplished through manipulating psychological or physiologic factors thus that the perception of a dyspneic stimulus is altered.

Distractive auditory stimuli (DAS) involve the use of auditory stimuli that keep the attention channels. DAS may bring the sensation and conscious perception of dyspnea, and thus dignify increased exercise tolerance. (8) Music has been used as a distractor in multiple populations and settings. (9-12) The varied positive benefits of DAS have included a significant increase in total exercise time and reduction in perceived exertion during exercise in patients with COPD (13) In ambulatory surgical patients, DAS has also been shown to decrease state anxiety, leading to a significant reduction in sedation requirement. (9) DAS has also been shown to facilitate a reduction in anxiety following acute myocardial infarction and during mechanical ventilation. (1011)
