Title : Effects of proprioceptive sensitivity stimulation via the sura electrodevice on kinematics, kinetics and spatiotemporal parameters of gait. Pilot study patient survivors of stroke
Abstract:
Background and Aims: Recovery of function in people with central nervous system (CNS) injury after stroke is very much like a relearning process that takes advantage of preserved sensorimotor circuits. Relearning can be optimised by providing appropriate proprioceptive (or deep sensory) information to the spinal cord with the aim of maximally engaging the preserved neural circuits. The development of the SURA electrodevice offers this sensitive input mechanism The study evaluates the impact of the SURA device on the functional recovery of stroke (CVA) patients, focusing on dynamic balance.
Methods: It is a randomized controlled clinical trial with 30 participants, dividing the subjects into an intervention group with the device activated and a control group without activation. The intervention included motor point stimulation of the gastrocnemius, soleus, and peroneal muscles, combined with standard rehabilitation sessions.
Results: Preliminary results showed significant improvements in balance (measured by the Berg scale), gait speed (10-meter walk test), and muscle strength, particularly in hip and ankle flexion and extension. Additionally, the intervention group demonstrated superior motor control, as reflected in electromyography, with more stable and synchronized muscle activation patterns, approaching values seen in healthy subjects. Improvements in joint range of motion in the hip and ankle were also observed, suggesting better control in the gait cycle.
Conclusions: The conclusions indicate that the SURA device could facilitate neuroplastic reorganization in stroke patients by providing a peripheral proprioceptive stimulus that influences the planning and execution of
motor commands. Its accessible and non-invasive nature positions it as a promising tool for community- based rehabilitation.
