New soft robotic exoglove reduces pain and spasticity for 12M patients
A glove that both massages spastic muscles and aids mobility—no existing solution does both.
Researchers from the paper (Salluce et al.) have developed a novel soft robotic exoglove designed to address both hand spasticity and pain—a dual challenge no existing solution tackles. The glove uses soft pneumatic actuators customized to an individual's hand topology and kinematics, ensuring optimal conformability and targeted mobility. Key innovations include a dorsal finger actuator that achieves full conformal contact, a ventral actuator compressible enough for hyperflexed spastic fingers, and a palmar actuator fabricated via stereolithography (3D printing) for complex geometries.
Actuators were analyzed with finite element modeling at 100 and 200 kPa to minimize stress before fabrication. The exoglove was assembled and successfully worn by a pilot user, validating comfort and initial effectiveness. This work targets the 12 million people worldwide suffering from hand spasticity due to stroke, arthritis, and nerve conditions. By integrating massage-like compression with mobility aid, the glove could offer a non-invasive, personalized therapy option. The paper will be presented at the IEEE RAS/EMBS BioRob 2026 conference.
- Soft pneumatic actuators are personalized to each patient's hand geometry for optimal fit and force distribution.
- Ventral actuator compresses to fit into the tight space of hyperflexed spastic fingers—a first for soft exogloves.
- Palmar actuator 3D-printed with stereolithography, enabling more complex actuator designs for future iterations.
Why It Matters
A non-invasive, personalized exoglove that manages both pain and mobility could transform rehabilitation for millions with spasticity.
