The Effect of Stretching Intensity on Pain Sensitivity

Not Applicable

Completed

• Conditions: Range of Motion; Stretching; Pain Threshold; Pain Sensitivity
• Interventions: Other: Static stretching

• Registration Number: NCT05989490
• Lead Sponsor: University College of Northern Denmark

Brief Summary

The primary objective of this study is to determine the immediate efficiency of stretching intensity on regional and distant pain sensitivity in healthy subjects. It is hypothesized that the analgesic effect of stretching may be linked with the intensity of stretching in a dose-response relationship.

Arm && Interventions

Group	Intervention	Description
Static stretching to the point of pain	Static stretching	The participants are assigned to four bouts of static stretching of the right knee flexors with a 20-second rest period between bouts 20 to the point of pain.
Static stretching to the point of discomfort	Static stretching	The participants are assigned to four bouts of static stretching of the right knee flexors with a 20-second rest period between bouts 20 to the point of discomfort.

Primary Outcome Measures

Name	Time	Method
Pressure pain thresholds	Pressure pain thresholds were measured immediately after stretching	Pressure pain thresholds was measures using a handheld pressure algometer

Secondary Outcome Measures

Name	Time	Method
Passive resistive torque	Passive resistive torque was measured immediately after stretching	Passive resistive torque was measured using the Biodex system 4 pro isokinetic dynamometer
Knee extension range of motion	Passive knee extension range of motion was measured immediately after stretching	Passively induced knee extension range of motion was measured using the Biodex system 4 pro isokinetic dynamometer
