An Investigation of Ball Rolling Effects on Trigger Points

Not Applicable
Not yet recruiting
Conditions
Trigger Point Pain, Myofascial
Interventions
Device: ball-rolling (Myostorm ball)
Registration Number
NCT05826834
Lead Sponsor
Memorial University of Newfoundland
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.

Primary Outcome Measures
NameTimeMethod
Range of Motion before ball rolling3 minutes before the intervention (Ball-rolling)

the range of motion in the shoulder joint

Pain pressure threshold before ball rolling3 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 rollingup to 3 minutes after the intervention (Ball-rolling)

the range of motion in the shoulder joint

Pain pressure threshold after ball rollingup to 3 minutes after the intervention (Ball-rolling)
