Purpose : Instrument-assisted soft tissue mobilization (IASTM) has been widely used to improve pain and range of motion. However, research on IASTM using vibration stimulation is lacking. Therefore, this study investigates how IASTM using vibration stimulation affects chronic pain on muscle activity and flexibility of the shoulders.
Methods : A total of 20 patients with chronic shoulder pain were divided into the experimental group and the control group. The experimental group (n=10) used vibration stimulus for IASTM, while the control group (n=10) used general IASTM. For six weeks, this training lasted for 30 min a day, twice a week. Muscle activity was evaluated using the surface electromyograph. The back and reach test was used to assess flexibility, the visual analogue scale to measure pain, and the paired t-test to compare the groups before and after the experiment. An independent ANCOVA was conducted to assess differences in the degree of transition between the two groups before and after the experiment.
Results : Significant differences in muscle activity, flexibility, and pain in both groups before and after the experiment (p<0.05) were observed, as well as in the muscle activity of the pectoralis major and associated pain (p<0.05). however, muscle activity and flexibility of the upper trapezius and infraspinatus were not significantly different between groups (p>0.05).
Conclusion : This study confirms the importance of IASTM using vibration. Design and manufacture of IASTM using vibration based on our results would be useful in the management of shoulder pain, Further clinical evidence are needed.
