Scientifically Validated Performance

Backed by authoritative experimental research conducted by Professor Hu Jie’s team at Shanghai Jiao Tong University, Bi-Stretch™ technology has been validated for its exceptional recovery performance.

Validated by Authoritative Research

Professor Hu Jie’s research team at Shanghai Jiao Tong University conducted a comparative study with 24 healthy adults, using surface electromyography (sEMG) and range of motion (ROM) as key objective metrics to systematically evaluate differences in muscle relaxation and functional improvement between stretching massage chairs and traditional massage chairs.

Muscle Relaxation Performance Comparison

Based on electromyography (EMG) analysis, Bi-Stretch™ technology demonstrated significantly superior relaxation effects across five key muscle groups compared to traditional massage chairs.
