The effects of live, taped, and no music on people experiencing posttraumatic amnesia

This study compared the effects of live, taped, and no music, on agitation and orientation levels of people experiencing posttraumatic amnesia (PTA). Participants (N = 22) were exposed to all 3 conditions, twice over 6 consecutive days. Songs used in the live and taped music conditions were identical and were selected based on participants' own preferred music. Pre and posttesting was conducted for each condition using the Agitated Behavior Scale (Corrigan, 1989) and the Westmead PTA Scale (Shores, Marosszeky, Sandanam, Batchelor, 1986). Participants' memory for the music used was also tested and compared with their memory for pictorial material presented in the Westmead PTA Scale. Results indicate that music significantly reduced agitation (p <.0001) and enhanced orientation (p <.001) however, the difference between live and taped music was not significant (p =.7). The mean number of pictures in the Westmead PTA scale recalled was 0.84 and the mean number of music selections recalled was 1.22 but this difference was not significant (p =.7). However, the trend suggests that music selections are more easily encoded in memory and then retrieved on request, than that of pictures. Analysis of responses in a follow-up assessment questionnaire showed that 77% of participants recalled the music program while in PTA, indicating that it reached the memory threshold. Sixty-four percent recalled the live music and 55% recalled the taped music condition however this difference was not significant (p =.7). Results suggest that music therapy programs have an important role to play in the management of people in PTA.
