Systematic review on wearable lower-limb exoskeletons for gait training in neuromuscular impairments.

Walking difficulties are common in people with neuromuscular conditions, and recovering some form of legged mobility is often a central goal of rehabilitation. This review looked at wearable powered exoskeletons, robotic devices worn on the legs that assist walking, by pulling together findings from 87 clinical studies covering both the technology itself and how it has been tested in patients. The picture that emerges is one of a promising but immature field. Exoskeletons appear to have potential for early rehabilitation, encouraging physical activity, and supporting daily activities at home or in the community, including for people who cannot walk unassisted.

However, the authors note that current devices are often heavy and bulky and typically need supervision or walking aids. Importantly, the clinical evidence behind these potential benefits comes mainly from small, short trials with varied methods, meaning the field has not yet demonstrated clinical efficacy through larger, well-controlled studies.

If you or someone you know has a condition that affects walking, you may have heard about robotic leg braces, called exoskeletons, that are designed to help people walk again or move more independently. This review looked across 87 studies to understand where this technology currently stands. The findings suggest these devices could eventually help with things like early rehabilitation after injury, staying physically active, and performing daily tasks both at home and out in the community, even for people who cannot walk on their own.

That said, the devices available now tend to be heavy and bulky, and using them often requires a therapist's supervision or additional walking aids like a walker. Perhaps most importantly, the evidence supporting these benefits still comes from small, short studies that used different methods, so it is too early to say how well these devices truly work for walking recovery. Larger, more rigorous trials are still needed before firmer conclusions can be drawn.

For clinicians weighing whether wearable lower-limb exoskeletons belong in gait rehabilitation planning, this review offers a structured look across 87 clinical studies, examining both device design (actuators, sensors, structural features) and clinical implementation (training protocols, outcome measures, patient populations) in people with neuromuscular impairments. The synthesis suggests potential applications spanning early rehabilitation, promoting physical activity, and supporting activities of daily living in home and community settings, including possible gains in mobility and independence for non-ambulatory patients.

However, the authors are explicit that the devices themselves remain limited by weight and bulk, often requiring supervision and concurrent use of walking aids, which constrains independent use. Clinically, the evidence base is characterized by short-duration interventions, small participant numbers, and considerable diversity in clinical protocols across studies, which limits comparability and the strength of conclusions that can be drawn about efficacy. This review does not establish that exoskeleton-based gait training produces clinically meaningful improvements over other approaches; it maps the current technological and research landscape and highlights that randomized controlled trials are still needed to determine clinical efficacy.

As a review of heterogeneous studies rather than a pooled trial, it inherits the limitations of its underlying small studies.
