Trigger Point Pain, Myofascial
Conditions
Brief summary
The current study aims to examine the potential effects of rolling a Myostorm ball on the trigger points in the upper back muscles.
Detailed description
The investigators will ask the participants to attend the laboratory in two sessions. They will seek the tender spots on the trapezius muscle. Then the participants will be asked to roll a Myostorm ball ( a small hard ball made of plastic with a layer of soft material cover) on their affected muscles. They will be tested for pain-pressure threshold (PPT), shoulder range of motion, electromyography (EMG), and force before and after the manipulation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Range of Motion before ball rolling | 3 minutes before the intervention (Ball-rolling) | the range of motion in the shoulder joint |
| Pain pressure threshold before ball rolling | 3 minutes before the intervention (Ball-rolling) | the measurement of the pain pressure threshold on the trapezius muscle using Lafayette Muscle Tester; A hand-held algometer will be applied on the participant's skin and an incremental pressure will be applied until the participant notify the experimenter to stop. The pain pressure threshold will be reported in kilogram/cm2. |
| Range of Motion after ball rolling | up to 3 minutes after the intervention (Ball-rolling) | the range of motion in the shoulder joint |
| Pain pressure threshold after ball rolling | up to 3 minutes after the intervention (Ball-rolling) | the measurement of the pain pressure threshold on the trapezius muscle using Lafayette Muscle Tester; A hand-held algometer will be applied on the participant's skin and an incremental pressure will be applied until the participant notify the experimenter to stop. The pain pressure threshold will be reported in kilogram/cm2. |
