The Effect of Stretching Intensity on Pain Sensitivity

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

Static Stretching

Other

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.

Primary outcomes

  1. 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

  2. Pressure pain thresholds

    Time frame: Pressure pain thresholds were measured immediately after stretching

    Pressure pain thresholds was measures using a handheld pressure algometer

Secondary outcomes

  1. Knee extension range of motion

    Time frame: Passive knee extension range of motion was measured as a baseline just prior to the induction of stretching to the point of pain and stretching to the point of discomfort

    Passively induced knee extension range of motion was measured using the Biodex system 4 pro isokinetic dynamometer

  2. Knee extension range of motion

    Time frame: 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

  3. Passive resistive torque

    Time frame: Passive resistive torque was measured as a baseline just prior to the induction of stretching to the point of pain and stretching to the point of discomfort

    Passive resistive torque was measured using the Biodex system 4 pro isokinetic dynamometer

  4. Passive resistive torque

    Time frame: Passive resistive torque was measured immediately after stretching

    Passive resistive torque was measured using the Biodex system 4 pro isokinetic dynamometer
