Study summary

The aim of our study is to determine and evaluate the effects of blood flow restriction technique on pain, biomechanical properties and strength of the muscle in delayed onset muscle pain in healthy individuals. A Double Blind, Randomized Controlled, prospective study was planned.

Read the detailed description

All participants will be taken into the DOMS creation protocol. Participants will then be divided into 80% intensity BFR and 20% intensity Blood Flow Restriction technique (BFR) groups and will be included in an exercise protocol accompanied by BFR application.

Interventions

  • OtherBFR technique

    For BFR application, Airbands brand, wireless, automatic training cuffs will be used. During application, it will be ensured that the device module faces forward and the cuff will be fixed in the correct position by wrapping the band around the metal ring. There will be a space between the skin and the cuff that can fit two fingers. The cuff will then be paired via Bluetooth with the Airbands app installed on the phone. BFR cuffs will be placed proximal to the biceps brachii muscle and pressure will be applied. The cuff will be inflated to automatically detect limb pressure. BFR application with 80% pressure to one group of participants and 20% pressure to the other group will be applied simultaneously with the exercise.

What researchers measure

Primary outcomes

  1. Visual analog scale

    it will be used for assessment of pain intensity, It is scored between 0-10, and higher scores indicate that the situation is getting worse.

    Time frame: 2 months

  2. myoton

    it will be used for assessment of muscle tonus and biomechanic properties, scores are changin according to different parameters.

    Time frame: 2 months

  3. dynamometer

    it will be used for assessment of myscle strength, lower scores indicate that the situation is getting worse.

    Time frame: 2 months

  4. dolorimeter

    it will be used for assessment of pain thresold pressure, lower scores indicate that the situation is getting worse.

    Time frame: 2 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2024 (actual). Primary completion is estimated for May 2024, 1 month after the start.

Of 3,734 non-industry interventional studies with no phase under Pain, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 23. This study's planned 1 month is below that.

Counting every sponsor, half of 3,833 studies reached it within 10 months; a quarter within 4 and three quarters within 23.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 30, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
