Intervention Procedures
The intervention group was asked to listen to the GRI
audio CD and the control group to the relaxation tracks
and songs of their choice twice a week for 6 weeks for 10
to 15 minutes a session. The time and day of the week
were their choice; but participants were asked to keep the
schedule consistent throughout the 6 weeks. Participants in
both groups were given an instruction booklet with a schedule
of tracks to listen to on certain days and a checklist
to monitor their progress during the 6 weeks. For consistency,
the researcher emphasized listening only to the set
of tracks on each chosen listening day as specified in the
instruction booklet. To encourage adherence to these
instructions, participants were asked to sign a trust agreement
letter stating that they would listen only to the given
track on the day listed in the instruction booklet. After
6 weeks, participants were retested using the same questionnaires
and mobility test used at baseline. The first
author facilitated all self-reported baseline and follow-up
measures and conducted the TUG.
