Abstract

Objectives: Falls in older adults represent a primary cause of decreased mobility and independence, increased morbidity, and accidental death. Research and clinical reports indicate that therapeutic massage (TM) may positively influence suggested causative factors. The second in a two-part study, this project assessed the effects of six weeks of TM treatment on balance, nervous system, and cardiovascular measures in older adults.

Design: A randomized controlled trial assessed the effects of six weekly 60-minute sessions of TM on balance, cardiovascular, and nervous system measures. Thirty-five volunteers (19 male and 16 female; ages 62.9 ± 4.6) were randomly assigned to relaxation control or TM groups. A 2 × 4 [treatment condition X time (week 1 and 6)] mixed factorial experimental design was utilized for cardiovascular/balance variables assessed at pretreatment baseline, immediate post-treatment, and 20- and 60-minutes post-treatment; nervous system measures were assessed only at pretreatment and at 60-minute follow-up (2 × 2 mixed design). Long-term benefits were assessed by comparing the TM and control groups on pretreatment baseline measures at week six and a follow-up assessment at week seven (2 × 3 mixed design).

Setting: Laboratory

Intervention: Six weekly 60-minute, full-body TM.

Outcome measures: Postural control/cardiovascular measures were assessed weeks one, six, and seven; pretreatment and immediate, 20- and 60-minutes post-treatment. Motoneuron pool excitability was assessed pretreatment and 60 minutes post-treatment.

Results: The TM group showed significant differences relative to controls in cardiovascular and displacement area/velocity after the week six session, with decreasing blood pressure and increasing stability over time from immediate post-TM to 60 minutes post-TM. The TM group revealed lower H-max/M-max ratios 60-minutes post-treatment. Long-term differences between the groups were detected at week seven in displacement area/velocity and systolic blood pressure.

Conclusions: Results suggest six weeks of TM resulted in immediate and long-term improvements in postural stability and blood pressure, compared to a controlled condition.

Keywords: blood pressure; falls; heart rate; postural control; sensorimotor.

Double- and single-legged stance. (a) A double-leg stance for the static balance test and H-reflex testing was assumed with two feet placed shoulder width apart and with hands on the hips. (b) A single-leg stance for the functional balance test and H-reflex testing was assumed with the non-stance extremity standardized in a position of 30 degrees of hip flexion and 90 degrees of knee flexion, with the ankle relaxed.
