The Effectiveness of Proprioceptive Neuromuscular Facilitation Exercise With Virtual Reality Motion Capture Gaming System and Concurrent Feedback on Early Shoulder Muscle Activation in Healthy Individuals
In Brief
A clinical study evaluating PNF exercise, PNF exercise with virtual reality gaming, and 1 other intervention for Exercise and Healthy. Completed, enrolled 30 participants across 1 site.
Detailed Summary
The study explores the effect of proprioceptive neuromuscular facilitation (PNF) exercises combined with virtual reality (VR) motion capture system and concurrent feedback (CF), on early shoulder muscle activation in healthy individuals. Thirty healthy individuals performed three PNF D2 shoulder exercises sequentially: first PNF alone, then PNF with VR (using U-Ball game (BeCure Global Inc.) on Xbox Kinect (PNF+VR), and PNF with VR and CF (PNF+VR+CF), with the latter two in a randomized order. Using wireless surface electromyography (EMG) and 3D inertial measurement units (Noraxon USA, Inc.), the activation of the upper trapezius (UT), lower trapezius (LT), infraspinatus (INF), and serratus anterior muscles (SA), along with shoulder flexion, abduction, and external rotation range of motion were recorded during three shoulder exercises.
Study Details
Timeline
Interventions
Foundational PNF D2 shoulder flexion exercise incorporating shoulder flexion, abduction, and external rotation. This exercise was performed at a metronome-guided pace of 14 beats per minute to establish a consistent baseline.
Combined the PNF D2 shoulder flexion exercise with a virtual reality motion capture game (the U-Ball game).
PNF exercise with the addition of auditory concurrent feedback ("Sword") which referenced the action of unsheathing a sword in a diagonal upward direction.
