Brief summary

This study will help determine if blood flow restriction (BFR) changes muscle activity on people performing single arm support while reaching with the opposite arm.

Detailed description

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.

Interventions

DEVICEBlood flow restriction unit

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.

Inclusion criteria

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

Design outcomes

Primary

Measure	Time frame	Description
Electromyography	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

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