Early Intelligent Active Assistance in Walking for Hemiplegic Patients under Suspension Protection: A Randomized Controlled Trial

• Early suspension-protected training with a personal assistant machine significantly improves walking speed, step frequency, stride length, and hip/knee flexion in early-stage hemiplegic stroke patients. • The experimental group showed a minimal increase in spasticity (modified Ashworth Scale score) compared to a large increase in the control group, indicating that the intervention helps prevent muscle spasms. • The combined use of suspension protection system and personal assistant machine facilitates the establishment of correct gait patterns and enhances motor function recovery. • The intervention is effective in reducing the support phase during gait, leading to more symmetrical and efficient walking.
