The Effect of Stretching Intensity on Pain Sensitivity

May 8, 2024 updated by: University College of Northern Denmark
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.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
31

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Healthy men and women aged 18-55 years are recruited. As part of the screening, volunteers will also be asked to indicate known medical issues or diseases.

Exclusion Criteria:

  • Participants are included if they have no known medical conditions such as; cognitive impairments, neurological, orthopaedic, or neuromuscular problems that might affect the somatosensory system or preclude stretching exercises or range of motion testing at the knee.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Static stretching to the point of pain
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.
Other: 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 and to the point of pain.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pressure pain thresholds
Time Frame: Pressure pain thresholds were measured as a baseline just prior to the induction of stretching to the point of pain and stretching to the point of discomfort
Pressure pain thresholds was measures using a handheld pressure algometer
Pressure pain thresholds were measured as a baseline just prior to the induction of stretching to the point of pain and stretching to the point of discomfort
Pressure pain thresholds
Time Frame: Pressure pain thresholds were measured immediately after stretching
Pressure pain thresholds was measures using a handheld pressure algometer
Pressure pain thresholds were measured immediately after stretching

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
