Providing Visual Biofeedback Using Brightness Mode Ultrasound During a Golf Swing

Area of Science:

• Sports Medicine
• Rehabilitation Science
• Biomechanics

Background:

• Ultrasound biofeedback is effective for static muscle training.
• Dynamic application of ultrasound biofeedback is less explored.
• Athletic populations require specialized rehabilitation techniques.

Purpose of the Study:

• To investigate the efficacy of ultrasound biofeedback for dynamic muscle strengthening in athletes.
• To assess the impact of ultrasound biofeedback on oblique muscle thickness during a golf swing.
• To explore the use of ultrasound biofeedback for improving muscle firing patterns in dynamic activities.

Main Methods:

• Utilized Brightness mode (B-mode) ultrasound with frame-by-frame video analysis.
• Secured ultrasound transducer to the abdomen for dynamic task monitoring.
• Analyzed changes in external and internal oblique muscle thickness during a golf swing.

Main Results:

• Ultrasound biofeedback combined with verbal cueing increased muscle thickness more than verbal cueing alone.
• Methodology allowed for immediate visual feedback to patients.
• Demonstrated potential for targeting specific muscle activation and timing during dynamic movements.

Conclusions:

• Ultrasound biofeedback is a viable tool to augment traditional rehabilitation for active individuals.
• This technique can be applied to dynamic sports-specific movements like the golf swing.
• Visual feedback via ultrasound can improve muscle activation and coordination in athletes.
