Central Motor Mechanisms in AIS Via HD-sEMG, EEG and Neuromuscular Coupling Analysis

The First Affiliated Hospital of Zhejiang Chinese Medical University40 enrolled

Overview

1. Verifying the Motor Control Effects of Spinal Manipulation on AIS Using outpatient and inpatient AIS patients from our department as the study subjects, standardized spinal manipulation treatment is applied. The efficacy is evaluated through a combination of clinical outcome measures, HD-EMG for paraspinal muscle function assessment, and Pro-Kin balance system for trunk stability analysis. This establishes an AIS efficacy platform to further clarify the effectiveness of spinal manipulation in motor control regulation of AIS. 2. Investigating the Central Motor Network's Response to Spinal Manipulation in AIS Utilizing high-density sEMG-EEG technology, synchronized brain and muscle electrical signals are collected before and after treatment. By employing a neuromuscular synchronization and coupling analysis approach that integrates linear and nonlinear methods, the characteristic indices of information interaction between the central system and muscles are identified. This further explores the motor control and response characteristics of the muscle-cortex network to spinal manipulation in AIS.

Conditions

Adolescent Idiopathic Scoliosis

Interventions

Tuina (Massage) Therapy

Operation Method: Correct abnormal joint alignment - Manipulatively realign the vertebral segments and pelvis affected by scoliosis. Correct abnormal muscle function - After realigning the vertebral bodies to their normal position, stretch the corresponding tight and shortened muscles while strengthening the muscles that need to be lengthened. Restore joint stability - After adjusting the vertebrae and muscles, instruct the patient to hold the corrected posture for at least 10 seconds, then relax for 10 seconds. Repeat this cycle 3-5 times. Restore sensorimotor control - Provide appropriate movement disturbances to patients maintaining the corrected posture to enhance proprioception and motor memory in the corresponding muscles. The total duration of the manipulation is 20-25 minutes. Treatment is performed twice a week for a total of 12 weeks.

Outcomes

Primary Outcomes

HD-EMG

Muscle performance was assessed using the SAGA high-density electromyography (EMG) system to evaluate the function and activity of the paraspinal muscles.

Time frame: Before treatment, and at 4 weeks and 12 weeks after treatment.

Secondary Outcomes

Pro-Kin Balance System

The Pro-Kin Balance System was used to assess trunk stability and evaluate motor control ability.
