Objective:
To investigate the clinical efficacy of transcutaneous electrical acupoint stimulation (TEAS) in treating children with autism spectrum disorders.
Methods:
Forty-one autistic children receiving rehabilitation training were randomized into TEAS (n=21) and control (n=20) groups. The control group only received rehabilitation training. The TEAS group received both rehabilitation training and TEAS treatment[2 Hz/15 Hz alternating frequencies through two pairs of skin electrodes placed at Hegu (LI 4)-Neiguan (PC 6) on unilateral side, and Zusanli (ST 36)-Sanyinjiao (SP 6) on the contralateral side]. The treatment was given 30 min per day for 12 weeks. The outcome assessment was quantified with a series of rating scales including Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS) and Parent Symptom Questionnaire (PSQ).
Results:
(1) The TEAS group showed more significant improvement than the control group in ABC (P<0.01). 38.1% effective rate (8/21) was observed in the TEAS group compared to 5.0% (1/20) in the control group (P<0.05). The CARS scores of both groups were reduced (P<0.0001) after treatment. The TEAS group showed significantly lower score compared to the control group (P<0.0001). (2)There was a distinctly reduced PSQ score in both TEAS and control groups (P<0.001) after treatment.(3)TEAS intervention showed better effect in children under 6 years old with moderate or severe autistic symptoms.
Conclusions:
TEAS intervention can significantly improve the autistic symptoms.
