Evaluating brain and technology interaction after below-knee amputation

Human-Prosthetic Interaction: Brain & Technology After Lower-Limb Loss

NA · Vrije Universiteit Brussel · NCT05818410

This study is testing how a new passive prosthetic ankle helps people who have had a leg amputated improve their walking and brain function compared to those without amputations.

What this trial studies

This study investigates the effects of a passive prosthetic ankle, Lunaris®, on brain neuroplasticity and functional performance in individuals with unilateral lower limb amputation. Participants will undergo MRI scans and functional performance tests at the University Hospital Brussels, comparing their outcomes with able-bodied individuals. The trial includes a rehabilitation phase where participants will learn to walk with either the Lunaris® or a conventional SACH foot® prosthesis, followed by an intervention period where they will use the assigned prosthetic device in daily activities.

Who should consider this trial

Good fit: Ideal candidates are individuals with unilateral transtibial (below knee) amputation who are healthy and classified as K3-4 on the Medicare Functional Classification.

Not a fit: Patients with neurological diseases, upper limb or bilateral amputations, osseointegration, metal implants, or diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance rehabilitation outcomes and quality of life for patients with lower limb amputations.

How similar studies have performed: While the approach of evaluating neuroplasticity in relation to prosthetic devices is innovative, similar studies have shown promising results in enhancing rehabilitation outcomes.
