About this study

This study will determine the muscular activation effects of blood flow restriction (BFR) on healthy subjects while they are performing the upper quarter y-balance test (UQYBT) with their dominant arm in stance.

Who can participate

Healthy volunteers accepted: Yes

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

Inclusion criteria

  • aged 18 to 30 years of age
  • able to perform a pushup position for one minute
  • able to follow simple commands

Exclusion criteria

  • no spine, upper extremity, or lower extremity pain
  • no spine, upper extremity, or lower extremity surgery or disorder in the past six months
  • no blood clotting or vascular disorder which would make BFR harmful

Treatment and study plan

Blood flow restriction unit

Device

A Delfi PTS (Personal Tourniquet System) unit wrapped around the proximal UE to occlude 50% of blood flow while the participant is performing the trials.

Primary outcomes

  1. Electromyography

    Time frame: Data will be collected on a single day only. 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.

    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.

Secondary outcomes

  1. UQYBT Reach Distances

    Time frame: Data will be collected on a single day only. 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.

    Centimeter reach distances on the UQYBT, which incorporates the UQYBT kit with calibrated length measurements built into the kit.
