- Brief Summary
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, within the Botton Up therapies. And through research on its use, the impact on the different dimensions related to gait and its components, and the translation to the functional reality of the person, will be evaluated.
- Detailed Description
Objective: To assess whether the SURA electrodevice improves relevant aspects of dynamic balance in stroke survivors.
Methods:The design is a prospective longitudinal randomised controlled trial with simple masking by the examiner to be carried out at the facilities of the Ricard i Fortuny Social and Health Centre (CSSV RiF). The first phase of the intervention (device-on rest phases) will consist of the activation of the device on the muscle motor points of the medial belly of the gastrocnemius, soleus and peroneus muscles. The motor points are the site of penetration of the motor nerve fibers and the highest concentration of motor plates in the muscle, which when stimulated produce the maximum effective muscle contraction. The second phase (OFF activity-device phase) consists of carrying out the therapy as the patient had been doing normally in the Neurorehabilitation department at the center at a rate of 3 sessions per week on an outpatient basis according to their individualized needs.
The control group will perform the same activity, but without the device activated during the device-on rest phases and adapted to the needs of each participant in their usual sessions without a standardized protocol.

- Primary Outcome Measures
Name Time Method The kinematics, kinetics and spatio-temporal parameters of gait. Start of intervention, at 4 weeks and at completion 8 weeks An instrumented gait analysis will be performed to obtain a set of spatiotemporal, kinematic and kinetic measurements.The movement will be captured by the Ephion Vitality system. The system consists of two pressure templates and seven inertial sensors (measuring linear acceleration, angular velocity and magnetic field in all three dimensions).
- Secondary Outcome Measures
Name Time Method Neuromuscular Activation Start of intervention, at 4 weeks and at completion 8 weeks Neuromuscular Activation Myontec surface electromyograph with sensors will collect the electrical activity of the lower limb muscles involved in gait coactivation. (Activation of motor units in milliseconds)
