Objective To investigate the temperature sensitization of back Fei-shu, Xin-shu, Gan-shu, Pi-shu and Shen-shu in spastic cerebral palsy (SCP) based on infrared thermal imaging. Methods 85 SCP patients who met the inclusion criteria were recruited, and the temperature of five backshu points on their back was detected by infrared thermal imager. The sensitization of acupoints was investigated and compared with 85 healthy subjects. Results Compared with healthy subjects, the temperature of Five-zang back-shu acupoints on the back of SCP patients was lower(P < 0.05), and the threshold value of acupoint sensitization existed. The sensitization rate of five back shu points in SCP children was higher than that in normal children. Conclusion Spastic cerebral palsy(SCP) is sensitized at Shu point in the back, which can provide reference for the auxiliary diagnosis and disease evaluation of CP.
