Официальное название
Proprioceptive Error Correction Technique Development to Promote Post-stroke Upper Limbs Motor Rehabilitation
Обзор
The investigators aim to develop sensory transformation and augmentation technologies that minimize the impact of proprioceptive errors, thereby significantly enhancing motor learning and rehabilitation of the upper limbs. This study is designed to test proprioceptive error compensation techniques in stroke patients. The human nervous system often receives mismatched information from vision and proprioception during upper limb control, resulting in conflicting sensory inputs that limit the effectiveness of motor learning. In other words, real-time sensory feedback - a critical component of motor learning in the nervous system - is not reliably delivered. Therefore, this study seeks to resolve sensory conflicts by providing additional sensory information through electrical stimulation, with the goal of dramatically improving the effectiveness of motor learning.
Вмешательства
- Поведенческое Electrical stimulation cue
A single 30-minute session is provided. Electrodes are attached to the cubital fossa, and stimulation is delivered at a frequency that increases up to 70 Hz as the elbow joint approaches the target angle. Target angles are set between 0 degrees and 120 degrees, based on each participant's available range of motion determined during the initial assessment. Participants adjust their elbow joint angle to match the provided target angle using feedback from the electrical stimulation. When the elbow - Поведенческое Visual stimulation cue
A single 30-minute session is provided. The difference between the current elbow joint angle and the pre-set target angle is displayed on a screen using two colored needles (a red needle for the target angle and a black needle for the current elbow joint angle). The target angle is set within each participant's available range of motion based on the initial assessment. Participants continue the intervention by adjusting their elbow angle using the visual feedback. When the elbow joint angle matc - Поведенческое No cue
A single 30-minute session is provided. The target angle is determined within each participant's available range of motion based on the initial assessment. Throughout the session, participants receive verbal feedback from the assessor and adjust their elbow joint angle accordingly to match the target angle.
