Not Applicable

Completed

• Conditions: Healthy
• Interventions: Other: Pain Inducing Stretch; Other: Cold Water Immersion; Other: Pain Free Stretch

• Registration Number: NCT05891353
• Lead Sponsor: University of Central Florida

Brief Summary

The purpose of this study is to characterize immediate changes in pain sensitivity during stretching to the point of pain, stretching in a pain free range, and a cold water immersion task. Participants will attend three sessions during which they will undergo pain sensitivity assessment and complete the assigned intervention.

Arm && Interventions

Group	Intervention	Description
Pain Inducing Stretch	Pain Inducing Stretch	Participants will be seated in a chair and asked to complete an upper trapezius stretch. They will feel a gentle stretch in the area between the top of their shoulder and the base of their neck. Participants will be asked to stretch until the point of pain. They will hold this stretch for 1 minute, 4 times. Change in Pressure Pain Threshold will be examined on the web space of their foot between each one minute interval of the stretch. Participants will be notified that they may stop the stretch at any point if needed.
Cold Water Immersion	Cold Water Immersion	Participants will complete a cold water immersion task to the hand for one minute, four times. Change in Pressure Pain Threshold will be measured between each one-minute interval on the web space of the foot between the first and second toes.
Pain Free Stretch	Pain Free Stretch	Participants will be seated in a chair and asked to complete an upper trapezius stretch. They will feel a gentle stretch in the area between the top of their shoulder and the base of their neck. Participants will be asked to stretch in a pain free range. They will hold this stretch for 1 minute, 4 times. Change in Pressure Pain Threshold will be examined on the web space of their foot between each one minute interval of the stretch. Participants will be notified that they may stop the stretch at any point if needed.

Primary Outcome Measures

Name	Time	Method
Change in Pressure Pain Threshold	Change in PPT is applied between minutes 1 and 4	A pressure algometer will be applied between the first and second toe until the pressure sensation first becomes painful. Pressure pain threshold is applied between each one minute interval of the intervention.
