What you'll learn

✓ Identify and optimize surface EMG signal quality from residual limb musculature
✓ Apply sEMG-guided training protocols to improve motor control signal consistency
✓ Evaluate functional outcomes of bionic prosthetic hand integration post-amputation

Protocol

Optimal functional outcomes after bionic reconstruction in patients with global brachial plexus injury depend on a structured rehabilitation protocol. Surface electromyographic guided training may improve the amplitude, separation and consistency of EMG signals, which - after elective amputation of a functionless hand - control and drive a prosthetic hand.

Difficulty

advanced

Total time

~8–12 weeks (rehabilitation protocol duration); individual training sessions ~30–60 min

Steps

Identify and characterize surface EMG signals

Locate and record sEMG signals from residual upper limb muscles following brachial plexus injury. Establish baseline signal amplitude, separation, and consistency metrics.

Conduct sEMG-guided signal training sessions

Implement structured biofeedback training to enhance EMG signal quality. Use real-time visual/auditory feedback to improve amplitude, separation, and reliability of motor signals for prosthetic control.

▶ 02:19

Perform elective amputation and prosthetic fitting

Execute surgical amputation of the functionless hand and establish prosthetic hand integration. Prepare residual limb interface for bionic device control via optimized EMG signals.

▶ 05:41

Analyze functional outcomes post-bionic reconstruction

Measure and compare prosthetic hand control performance, EMG signal quality metrics, and functional recovery in global brachial plexus injury patients after bionic reconstruction.
