Donor Activation-focused Rehabilitation Approach: Maximizing Outcomes After Lower Extremity Nerve Transfers

Area of Science:

• Neurosurgery
• Rehabilitation Medicine
• Peripheral Nerve Injury

Background:

• Nerve transfers are crucial for managing peripheral nerve injuries.
• A donor activation-focused rehabilitation approach (DAFRA) significantly improves outcomes post-nerve transfer surgery compared to general physical therapy.
• Lower extremity nerve transfers require specialized rehabilitation due to weight-bearing and ambulation demands.

Purpose of the Study:

• To present optimal DAFRA protocols for common lower extremity nerve transfers.
• To restore hip stability, knee extension, and ankle mobility following nerve transfers.
• To guide rehabilitation for patients with lower extremity nerve injuries undergoing nerve transfers.

Main Methods:

• DAFRA strengthens neural pathways by respecting altered anatomy.
• The approach encourages cortical plasticity and patient education.
• Therapy is divided into early, middle, and late phases tailored to individual patient needs.

Main Results:

• The DAFRA program's progression is individualized, not based on a fixed timeline.
• Recovery phases are adapted to each patient's specific needs and progress.
• This flexible approach supports optimal recovery from nerve transfers.

Conclusions:

• DAFRA provides a structured yet adaptable framework for lower extremity nerve transfer rehabilitation.
• Optimized DAFRA protocols are essential for functional recovery, including hip, knee, and ankle function.
• Patient-centered, phased rehabilitation is key to successful outcomes in lower extremity nerve repair.
