Muscle Stretching - the Potential Role of Endogenous Pain Inhibitory Modulation on Stretch Tolerance

NCT ID: NCT03713788

Last Updated: 2018-10-22

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 34 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2016-05-01

Brief Summary

This study investigates the influence of a remote, painful stimulus on stretch tolerance. Half of the participants will receive a conditioning painful stimulus following static stretching while the other half will rest quietly.

Detailed Description

The effect of stretching on joint range of motion is primarily related to changes in the tolerance to stretch, but the mechanisms underlying this change are still largely unknown.

The nervous system has an inbuilt ability to modulate the perceived magnitude of afferent noxious stimuli via supraspinally mediated endogenous pain inhibition or facilitation and by engaging endogenous mechanisms pain tolerance in healthy individuals is known to increase. Thus increasing the tolerance to pain could potentially increase range of motion following stretching.

Study Groups

Experimental pain group

subjects in the pain group were instructed to immerse their non-dominant hand into a container with circulating water at 1˚C to 4˚C and keep it there for 2 minutes. They were instructed to immerse it to wrist-level and keep the hand open.

Cold pressor test

Intervention Type: OTHER

Participants placed their non-dominant hand into cold water for 2 minutes

Control group

Participants rested in a seated position for 5 minutes.
