Outcome Measures

Primary Outcomes (1)

  • 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.

    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.

Secondary Outcomes (1)

  • UQYBT Reach Distances

    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.

Study Arms (1)

Cohort performing the Upper Quarter Y-Balance Test with and without BFR applied to their arm

Cohort of 30 healthy participants

Device: Blood flow restriction unit

Interventions

Blood flow restriction unitDEVICE

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.

Cohort performing the Upper Quarter Y-Balance Test with and without BFR applied to their arm
