Male (8) and female (22) Essential Hypertensives (130/85 mm Hg or above) were randomized into a nonspecific treatment or an experimental treatment utilizing eight relaxation strategies. Both groups had eight training sessions which consisted of baseline blood pressures (BP), 15 minute relaxation tapes, and post-relaxation BP's. Subjects were instructed to use their tapes three times between sessions. Five BP readings were taken at the one and two month follow-ups. It was hypothesized that the experimentals would have greater within and across session decreases in BP, and that the differences would be maintained during a no treatment follow-up.

Male (8) and female (22) Essential Hypertensives (130/85 mm Hg or above) were randomized into a nonspecific treatment or an experimental treatment utilizing eight relaxation strategies. Both groups had eight training sessions which consisted of baseline blood pressures (BP), 15 minute relaxation tapes, and post-relaxation BP's. Subjects were instructed to use their tapes three times between sessions. Five BP readings were taken at the one and two month follow-ups. It was hypothesized that the experimentals would have greater within and across session decreases in BP, and that the differences would be maintained during a no treatment follow-up. Eleven experimentals and 8 controls were on medication. Mean medication compliance percentages were 99.9 and 99.6 while mean relaxation compliance percentages were 95.2 and 115.2 for experimentals and controls respectively. Efficacy was checked at each training session on a seven-point scale and group means were 6.5 and 5.4 for experimentals verses controls. Within session decreases in BP were compared with t tests and no significant differences (p < .05) were present for the eight training sessions with systolic (SBP) or diastolic (DBP). Across session changes were compared with ANCOVA and no significant differences (p < .05) were present for the eight training or two follow-up sessions for SBP or DBP. In summary, the experimentals showed within and across session decreases in BP consistent with prior research, but the effect was not significantly better than "sitting quietly". It was concluded that nonspecific treatments must be included in BP research on effectiveness of treatments. A final conclusion was that both groups did show clinically useful decreases in BP which were maintained at follow-up and the effectiveness of noninvasive treatments for Essential Hypertension was demonstrated.
