Abstract

Sustained manual pressure has been advocated as effective treatment for myofascial trigger points (MTrPs). This study aimed to investigate the effect of manual pressure release (MPR) on the pressure sensitivity of MTrPs in the upper tapezius muscle using a novel pressure algometer. Asymptomatic subjects were screened for the presence of latent MTrPs in the upper trapezius muscle (tender band that produced referred pain to neck and /or head on manual pressure). Subjects were randomly allocated into either the treatment (MPR) or control (sham myofascial release) groups. The pressure pain threshold (PPT) was recorded pre and post treatment intervention using a digital algometer, consisting of a capacitance sensor was attached to the tip of the palpating thumb. There was a significant increase in the mean PPT of MTrPs in the upper trapezius following MPR. There was no significant change in the PPT following the sham treatment in the control group. Perceived tenderness and tolerance to pressure significantly decreased during the application of MPR. The pressure sensitivity of MTrPs was immediately reduced following application of MPR, and the reduction in tenderness during application of MPR was due to a change in tissue sensitivity, rather than an unintentional reduction of pressure by the examiner. MPR appeared to be an effective therapy for MTrPs in the upper trapezius muscle. This minor thesis was written by a post-graduate student as part of the requirements of the Master of Health Science (Osteopathy) program.
