Can a powered ankle brace help people with foot drop walk faster
Official title: Evaluation of the NEUROSWING Orthosis on Walking Speed in a Population With Dorsal and/or Plantar Flexor Deficits, With a View to a Reimbursement Application. Clinical Investigation: NS-BOOSST
Run by ÖSSUR France · NCT07108088 · Data updated 2026-11-12
This study tests whether the NEUROSWING orthosis can improve walking speed in adults with dorsal and/or plantar flexor deficits compared with a carbon brace.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with dorsiflexor or plantarflexor deficits who can walk with or without aids and are new users of the study orthosis.
✕Probably not a fit
Patients with cognitive impairment or progressive conditions that could severely affect walking may derive little or no benefit.

What this trial studies
This randomized, cross-over, multi-center study compares two 14-day periods of wearing the NEUROSWING orthosis versus a carbon orthosis, with a one-week washout in between. Participants with dorsal and/or plantar flexor deficits related to stroke, MS, CP, or neuromuscular issues will be assessed using the 10-meter walk test and secondary gait measures. The trial uses intention-to-treat analysis and open-label design, with walking speed as the primary endpoint and additional gait assessments as secondary endpoints.
Why it matters
Potential benefit: If successful, the NEUROSWING device could improve gait speed and overall mobility for patients who rely on ankle/foot support.
How similar studies have gone: Prior related studies have explored functional ankle devices; this trial adds a cross-over design to compare active versus standard orthoses.
