Summary

This study illustrates the effect of selective spinal manipulation on the growth and development of infant rats with cerebral palsy, emphasizing the specific procedure and standardized protocol. Body weight measurement, Rotarod test, Foot-fault score, other behavioral tests, and growth hormone detection were performed to evaluate the protocol.

Abstract

Cerebral palsy (CP) is a refractory pediatric disease with a high prevalence, high disability rate, and difficult treatment. A variety of treatments are currently used for CP. The treatment involves drug and non-drug therapy. Traditional Chinese medicine external therapy is a very distinctive treatment method in non-drug therapy. As one of the external therapies of traditional Chinese medicine, massage is used in treating cerebral palsy and has good efficacy, small side effects, and strong operability. As a part of TCM external therapy, selective spinal manipulation can effectively promote the growth and development of infant rats with cerebral palsy.The operation was mainly divided into four steps: first, the rubbing method was applied to the spine and both sides of the spine for 1 min. The pressing and kneading method was applied to the spine for 5 min, and the muscles on both sides of the spine for 5 min. Second, pressing and kneading the sensitive local acupoints in the spine for 2 min were performed. Thirdly, the affected limb was treated by twisting method for 1 min. Fourth, the rubbing method was applied to a midline from the forehead to the back of the brain for 1 min. This study aimed to use selective spinal manipulation to treat infant rats with cerebral palsy. The weight, Rotarod test, Foot-fault score, and growth hormone of infant rats with cerebral palsy were detected to understand the effect of selective spinal manipulation on the growth and development of infant rats with cerebral palsy. The results showed that it can promote weight gain, improve balance ability and motor function, promote growth and development of infant cerebral palsy rats, promote growth hormone secretion, and increase the temperature of sensitive parts of the back.

Introduction

Cerebral Palsy (CP), caused by non-progressive damage to the brain in the fetus or infancy, is a group of disorders characterized by abnormal motor and postural development1, developmental disorders including slow weight gain2,3,4, and motor dysfunction. The incidence of cerebral palsy in China is 2.48%, and the prevalence is 2.46‰ (1-6 years old)5, respectively. Foreign studies reported a prevalence of 2.4%-3.6%6. Cerebral palsy is a major cause of physical injury and disability in children, among ....

Protocol

This study was approved by the Experimental Animal Ethics Committee of Yunnan University of Traditional Chinese Medicine. All experimental operations on animals followed the 3R principle of experimental animal reduction, optimization, and replacement (No. R-06202018). Healthy Sprague Dawley (SD) rats (14 males and 7 females) of Specific pathogen-free (SPF) grade with an average body weight of 250-300 g were used in this experiment. The rats were raised in the SPF animal room of Yunnan University of Traditional Chinese Me.......

Representative Results

Selective spinal manipulation can promote body weight gain in infant rats with cerebral palsy.
During the treatment, body weight was measured on postnatal days 3, 14, 28, 42, and 61 (Figure 4, Table 3). On the third day after birth, the body weight of the Sham group was 5.53 ± 0.035 g, and the body weight of the Control group was 3.15 ± 0.43 g. The body weight of the Treatment group was 4.42 ± 0.13 g, and it was not significantly differe.......

Discussion

Because ischemia and hypoxia are important pathogenic factors of cerebral palsy, the internationally recognized method of establishing the cerebral palsy model is combined with hypoxia to prepare the cerebral palsy model16,28,29,30. When cerebral palsy develops, it causes global developmental delay, including weight and motor function, which may be related to the level of growth hormone secreti.......
