Effects of Combined Neuromuscular Electrical Stimulation Robot and Trans-Spinal Electrical Stimulation in Poststroke Rehabilitation

Официальное название

Restoring Functional Capacity of the Upper Extremity Using Combined Neuromuscular Electrical Stimulation Robot and Trans-Spinal Electrical Stimulation in Individuals With Chronic Stroke

Обзор

The purpose of this study is to investigate the clinical efficacy and neurological progress of combined training using trans-spinal electrical stimulation (tsES) and neuromuscular electrical stimulation (NMES)-driven robotics on upper limb rehabilitation after stroke

Подробное описание

This study aims to explore whether a multimodal intervention that combines central neuromodulation through trans-spinal electrical stimulation (tsES), peripheral activation via neuromuscular electrical stimulation (NMES), and task-specific robotic training can enhance upper limb recovery.

Specific objectives:

1. To evaluate the clinical efficacy of combining tsES and NMES robotic training for enhancing upper limb motor function in post-stroke patients. 2. To quantify the neurological progress of the tsES and NMES robot combined interventions in the rehabilitation process using electrophysiological tracers (electroencephalogram, electromyogram) and kinesiological recorder (Inertial Measurement Unit) 3. To investigate the central-to-peripheral neuroplasticity by corticomuscular coherence evaluation in poststroke rehabilitation

Вмешательства

• Устройство Electrical Stimulation; Rehabilitation Robot
  The recruited subjects will receive 20 sessions of robot-assisted upper limb training combined with central-to-peripheral electrical stimulation, delivered at a frequency of 3 to 5 sessions per week, which will be completed within 4 to 7 consecutive weeks. Each rehabilitation session will begin with a 10-minute preparation phase, followed by 20 minutes of NMES and tsES-assisted robotic training. After a 10-minute break, the session will continue with an additional 20 minutes of robotic-assisted
• Поведенческое Occupational Therapy with Electrical Stimulation
  The recruited subjects will receive 20 sessions of task-oriented occupational therapy(OT) combined with trans-spinal electrical stimulation(tsES), delivered at a frequency of 3 to 5 sessions per week, which will be completed within 4 to 7 consecutive weeks. Each rehabilitation session will begin with a 10-minute preparation phase, followed by 20 minutes of OT training with tsES. After a 10-minute break, the session will continue with an additional 20 minutes of COT alone, with tsES turned off du
• Поведенческое occupational therapy with sham electrical stimulation
  The recruited subjects will receive 20 sessions of task-oriented occupational therapy(OT) combined with sham trans-spinal electrical stimulation(tsES), delivered at a frequency of 3 to 5 sessions per week, which will be completed within 4 to 7 consecutive weeks. Each rehabilitation session will begin with a 10-minute preparation phase, followed by 20 minutes of OT training with 0mA-intensity tsES. After a 10-minute break, the session will continue with an additional 20 minutes of COT alone, with
