Contralateral Blood Flow Resistance Improves Scapular Muscle Activation During Pickleball Forehand Swings
An observational study of Shoulder and Upper Arm Injury, run by Texas Woman's University at 1 site in United States.
Trial summary
Participants will perform table tennis, pickleball, and tennis swings while arm and leg muscles are analyzed with surface electromyography. Then blood flow resistance will be added to the non-swinging arm. Read more about this study

About this study
Participants will perform table tennis, pickleball, and tennis swings while arm and leg muscles are analyzed with surface electromyography. Then blood flow resistance will be added to the non-swinging arm.
Read the detailed description
Participants will perform forehand, backhand, and overhead swings of table tennis, pickleball, and tennis swings while making contact with a tethered ball of that sport. Surface electromyography of the lower trapezius, serratus anterior, anterior deltoid, biceps, and extensor carpi brevis will be recorded. Then participants will perform the entire protocol with blood flow resistance added to the non-swinging arm.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Cohort performing the 3 sports swings with and without BFR applied to their arm Group/C | Cohort of 30 healthy participants |
What is being measured
The primary outcome is the main question the study is designed to answer.
Surface Electromyography
UE and scapular EMG using Delsys Electromyography Unit with Trignio electrodes on the lower trapezius, serratus anterior, anterior deltoid, biceps brachii, and extensor carpi radialis brevis.
Measured: Data will be collected on a single "baseline" day. Each subject will only have data collection on one single day. The time frame will be only one hour from the start of data collection to the end. No follow up trials or data collection.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Surface Electromyography (time frame: Data will be collected on a single "baseline" day. Each subject will only have data collection on one single day. The time frame will be only one hour from the start of data collection to the end. No follow up trials or data collection.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
