简要总结
The primary objective of this clinical trial is to investigate the efficacy of Epidural Electrical Stimulation (EES) in restoring motor and sensory function in patients with chronic spinal cord injury (SCI) at levels T11-L3, classified as ASIA B-D. The study aims to address the following key questions: Does EES lead to significant improvement in motor and sensory function compared to baseline in this patient population? To assess the longitudinal effects of EES, researchers will compare participants' motor function, sensory function, and quality of life measures at multiple time points: prior to EES implantation, immediately after device activation, and at 1, 3, and 6 months post-implantation. Participants will be required to:Undergo surgical implantation of an EES device in the epidural space. Have the device activated and receive individualized stimulation parameter adjustments during follow-up visits. Complete regular motor and sensory assessments using standardized protocols. Participate in structured rehabilitation training sessions while using the EES device. Report any adverse events and complete quality-of-life questionnaires at predetermined intervals.

结局指标
主要结局
WISCI II (Walking Index for Spinal Cord Injury II)
时间窗: baseline, and 1, 3, 6 monthes after surgery
The WISCI II evaluates walking ability in spinal cord injury patients. It has 21 levels (0-20), with scores based on mobility aids, assistance needed, and walking distance. A score of 0 means no walking; 20 indicates independent walking over 500 meters without aids. It tracks recovery progress and helps tailor rehabilitation plans for locomotor function.
Functional Independence Measure (FIM)
时间窗: baseline, and 1, 3, 6 months after surgery
The Functional Independence Measure (FIM) is a widely used assessment tool designed to evaluate a person's functional status and level of independence in daily living activities, particularly among individuals with disabilities. FIM items are scored based on the level of assistance required to complete a task, ranging from 1 to 7 points per item. The FIM consists of 18 items across two domains: Motor domain (13 items): Includes activities such as eating, grooming, bathing, dressing, toileting, transfers (bed/chair, toilet, tub/shower), walking, and stair climbing. Cognitive domain (5 items): Covers communication (comprehension and expression) and social cognition (memory, problem-solving, and social interaction). The total score ranges from 18 to 126 points: ≤ 35 points: Severe dependence 36-89 points: Moderate dependence 90-119 points: Mild dependence 120-126 points: Functional independence
