RESUMEN
OBJECTIVE@#To investigate clinical biomechanical principle of brace with stiletto needle therapy for scoliosis.@*METHODS@#Based on design ideas of teasing needle therapy, building an experimental mechanical model was built, seven specimens with scoliosis were chosen, and treated by brace therapy and then added to stiletto needle therapy.@*RESULTS@#The two experimental mechanical model methods could predict load of scoliosis by stiletto needle therapy, and was verified accuracy and effectiveness of model. The degree of initial scoliosis of 7 patients was (59.7±3.37)°, improved to (49.57±2.79)° by correction of brace, and (39.43±1.94)° by correction of brace with stiletto needle therapy, had significant differences(<0.05). Lateral distraction force of thoracolumbar fossa from scoliosis as V, compressive force of scoliosis as T, brace with stiletto needle therapy could save effort for 45% to 46% than that of brace, while running torque Mw and compressive torque Mv could save effort about 45% to 47%, save effort of tension torque MT of muscle and ligament for 52%, and had statistical difference(<0.05).@*CONCLUSIONS@#Experimental biomechanical model of teasing needle therapy confirmed that the therapy could significantly reduce Cobb angle, improve correction efficiency of brace and beneficial for correction effect. It is an effective treatment for scoliosis.
