Objective: Sensory impairment in the affected upper limb occurs in approximately 50% of post-stroke patients and negatively impacts functional capacity and quality of life. This pilot study aims to evaluate whether the standardized use of pneumatic (air) splints, as part of a neurodevelopmental treatment approach, will have a positive effect on sensorimotor deficits in the hemiplegic upper limb of post-stroke patients.

Design: Pilot randomized, single-blind clinical trial.

Setting: Brain injury rehabilitation facility.

Participants: Twenty adults in the subacute phase after stroke will be randomized into two groups. The experimental group (n = 10) will receive air splint therapy combined with physiotherapy (45 minutes per session, twice per week for 4 weeks). The control group (n = 10) will receive only physiotherapy with the same duration and frequency. Sensorimotor outcomes will be assessed using the Fugl-Meyer Assessment for the Upper Extremity (FMA-UE), and finger flexor/extensor strength will be measured using the Amadeo robotic system. Assessments will be conducted before and after the intervention.

Conclusions: The addition of air splints to physiotherapy may enhance exteroceptive and proprioceptive sensitivity in adults recovering from stroke during the subacute phase.
