A functional splint for the C5 tetraplegic arm

Area of Science:

• Orthotics and Prosthetics
• Rehabilitation Engineering
• Neuroscience

Background:

• C5 complete tetraplegia often results in involuntary forearm flexion and supination, limiting upper limb function.
• Existing assistive devices may not adequately address the specific challenges faced by C5 tetraplegic individuals.
• Restoration of active forearm control is crucial for improving independence and quality of life.

Observation:

• A novel orthosis was developed to facilitate active extension and pronation of the forearm.
• The orthosis design specifically targets the functional deficits associated with C5 complete tetraplegia.
• Clinical application and technical specifications of the orthosis are detailed.

Findings:

• The presented orthosis successfully provides active extension and pronation capabilities for C5 complete tetraplegic users.
• The device demonstrated efficacy in overcoming and preventing the characteristic flexed and supinated posture of the C5 tetraplegic arm.
• A case report highlights the positive functional outcomes and usability of the orthosis.

Implications:

• This innovation offers a significant advancement in assistive technology for C5 tetraplegia.
• Improved forearm control can enhance participation in daily activities and increase self-sufficiency.
• Further research and wider adoption of this orthosis could substantially benefit the C5 tetraplegic community.
