Abstract:
Context Drum circles have been part of healing rituals
in many cultures throughout the world since antiquity. Although drum
circles are gaining increased interest as a complementary therapeutic
strategy in the traditional medical arena, limited scientific data
documenting biological benefits associated with percussion activities
exist.
Objective To determine the role of group-drumming
music therapy as a composite activity with potential for alteration
of stress-related hormones and enhancement of specific immunologic
measures associated with natural killer cell activity and cell-mediated
immunity.
Design A single trial experimental intervention
with control groups.
Setting The Mind-Body Wellness Center, an outpatient medical facility
in Meadville, Pa.
Participants A total of 111 age- and sex-matched
volunteer subjects (55 men and 56 women, with a mean age of 30.4
years) were recruited.
Intervention Six preliminary supervised groups were
studied using various control and experimental paradigms designed
to separate drumming components for the ultimate determination of
a single experimental model, including 2 control groups (resting
and listening) as well as 4 group-drumming experimental models (basic,
impact, shamanic, and composite). The composite drumming group using
a music therapy protocol was selected based on preliminary statistical
analysis, which demonstrated immune modulation in a direction opposite
to that expected with the classical stress response. The final experimental
design included the original composite drumming group plus 50 additional
age- and sex-matched volunteer subjects who were randomly assigned
to participate in group drumming or control sessions.
Main Outcome Measures Pre- and postintervention
measurements of plasma cortisol, plasma dehydroepiandrosterone, plasma
dehydroepiandrosterone-to-cortisol ratio, natural killer cell activity,
lymphokine-activated killer cell activity, plasma interleukin-2,
plasma interferon-gamma, the Beck Anxiety Inventory, and the Beck
Depression Inventory II.
Results Group drumming resulted in increased dehydroepiandrosterone-to-cortisol
ratios, increased natural killer cell activity, and increased lymphokine-activated
killer cell activity without alteration in plasma interleukin 2 or
interferon-gamma, or in the Beck Anxiety Inventory and the Beck Depression
Inventory II.
Conclusions Drumming is a complex composite intervention
with the potential to modulate specific neuroendocrine and neuroimmune
parameters in a direction opposite to that expected with the classic
stress response.
