Abstract:
This study optimized therapeutic parameters for adhesive capsulitis (AC) using a hybrid method integrating medium-frequency electrical stimulation (MFES) and far-infrared rays (FIR). The Taguchi design analyzed three factors—FIR intensity, MFES mode, and treatment sequence—across nine parameter sets, evaluated by VAS, QD, RMS, and iEMG. Genetic algorithm (GA) optimization identified the optimal combination as FIR at medium–low intensity, MFES 6/6 square-wave mode, with FIR applied before MFES, achieving improved muscle relaxation, pain reduction, and functional recovery. The integrated Taguchi–GA framework demonstrated high optimization efficiency and provides a quantitative model for developing evidence-based physical therapy protocols for shoulder adhesive capsulitis.
