Details and patient eligibility

About

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.

Enrollment: 30 patients

Sex: All

Ages: 18 to 60 years old

Volunteers: Accepts Healthy Volunteers

30 participants in 3 patient groups

Cold Water Immersion

Active Comparator group

Description:

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.

Treatment:

Other: Cold Water Immersion

Pain Inducing Stretch

Experimental group

Description:

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.

Treatment:

Other: Pain Inducing Stretch

Pain Free Stretch

Active Comparator group

Description:

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.

Other: Pain Free Stretch
