Tendon-lengthening surgery versus botulinum toxin injections for hand and wrist spasticity

The Effectiveness of Spasticity-correcting Upper Limb Surgery Versus Botulinum Toxin Injections in Patients With Upper Limb Spasticity: an Experimental Study With Paired Design

Not applicable Interventional Vastra Gotaland Region · NCT06733025

This project tries to see if tendon-lengthening surgery helps adults with hand and wrist spasticity after stroke, spinal cord injury, or traumatic brain injury more than ongoing botulinum toxin injections.

What this trial studies

This open-label, non-randomized paired-design study at Sahlgrenska University Hospital compares tendon lengthening surgery to ongoing botulinum toxin (BoNT) injections for upper-limb spasticity affecting hand and wrist function. Eligible adults are at least six months post-injury (stroke, TBI, or SCI), currently receiving BoNT with at least three months since their last injection, and have at least two hand/wrist muscles considered for treatment. Participants either undergo tendon-lengthening surgery with standard postoperative care or continue BoNT injections combined with community therapy, and outcomes focus on hand function, activities of daily living, and longer-term spasticity control. The team uses a stratified surgical algorithm based on residual motor function and follows patients over time to compare durable functional benefits.

Who should consider this trial

Good fit: Adults (18+) with problematic upper-limb spasticity after stroke, TBI, or spinal cord injury who have been on BoNT treatment for the hand/wrist, are at least six months post-injury, and are medically stable for surgery are ideal candidates.

Not a fit: Patients with recent injury under six months, fewer than two affected hand/wrist muscles, major concurrent upper-limb injuries, or who are not medically fit for surgery may not benefit from or be eligible for the surgical arm.

Why it matters

Potential benefit: If successful, surgery could provide longer-lasting improvement in hand function and independence compared with repeated BoNT injections.

How similar studies have performed: Surgical approaches for focal upper-limb spasticity have shown promising long-term results in case series, but there are few high-quality comparative trials directly contrasting surgery with BoNT.
