Feasibility of distractive auditory stimuli on upper extremity training in persons with chronic obstructive pulmonary disease.
OBJECTIVE
To determine the feasibility of distractive auditory stimuli (DAS) used during an upper extremity training (UET) program on perceived dyspnea, functional performance, and health-related quality of life. In addition, to determine the appropriate music tempo used during the UET.


METHODS
Experimental, randomized, 3-group design with testing at baseline and 4 weeks.


METHODS
Outpatient.


METHODS
Thirty patients (13 male and 17 female) with moderate to severe chronic obstructive pulmonary disease (FEV1 41.27% +/- 18% predicted).


METHODS
Moderate DAS group (n = 10) and slow DAS group (n = 10) subjects were instructed to perform UET for up to 15 minutes 3 to 5 times a week using DAS (walkman, audiocassettes). The control group (n = 10) received the same instructions, but no DAS.


RESULTS
Primary outcome measures were perceived dyspnea, functional performance using the 6-minute peg and ring board (6MRPB) count and health-related quality of life. In addition, all subjects recorded the time of UET performance using self-report (daily logs). A significant increase was seen in 6MRPB count (P = .002) between groups. Moderate DAS subjects increased 6MPRB count 46 +/- 21 rings and slow DAS subjects increased 46 +/- 20 rings from baseline to 4 weeks whereas control subjects increased only 5 +/- 4 rings. No significant differences were noted for the remaining variables.


CONCLUSIONS
Subjects who used DAS (music) while performing UET improved functional performance whereas controls failed to continue improvement. The DAS is a feasible adjunct to UET that may have the potential to augment the effectiveness of pulmonary rehabilitation training.
