- Abstract
- Objective: This study investigates whether myo-fascial unwinding performed on the shoulder complex does increase blood-flow volume and rate through the brachial artery at a statistically significant level, as compared to a sham technique. Hypothesis (H1): Myo-fascial unwinding will increase the blood flow through the brachial artery at a statistically significant level. Null Hypothesis (H0): Myo-fascial unwinding will have no greater effect on increasing blood flow through the brachial artery at a statistically significant level than that of rubbing the trapezius muscle. Design: This study was based on primary data gathering using 18 subjects, divided into two groups of nine subjects, in a randomized control trial. The subjects were volunteers from the ESO student body. (note. The groups were unmatched for gender. The experimental group had a ratio of five males to four females, whereas the sham treatment group had a ratio of four males to five females). Intervention: 9 subjects received fascial unwinding of the left shoulder complex, and 9 subjects received a sham treatment, consisting of rubbing the trapezius muscle. Both subject groups had their treatments administered by the researcher. Outcome measure: Brachial artery blood flow, from the right arm, was measured immediately before the administration of any treatment, immediately after treatment, and one week after treatment. Additionally blood pressure and pulse measurements were obtained in the same intervals, from the left arm. Results@ ANOVA testing showed no statistical significant increase in blood flow through the brachial artery, neither volumetrically, nor in rate (p > 0.05). However following re-zeroing of the percent change for the intervals before/after and after/follow-up there was a statistical significant increase in brachial artery blood flow volume in the before/after interval (p = 0.004) and after/follow-up interval (p=0.002). Conclusion: Myo-fascial unwinding of the shoulder complex did produce a statistical significant increase in brachial artery blood flow, however this was only shown after re-zeroing the percent change in the data for before/after and after/follow-up intervals Testing on a larger scale should be conducted.
