Enhancing the Development and Growth of Infant Cerebral Palsy Rats Using Selective Spinal Manipulations
February 2nd, 2024
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.
This research reveals the possible mechanism of selective spinal manipulation in the improving the growth and development of infant rats with cerebral palsy from the perspective of animal behavior and the molecular biology. Selective spinal manipulation is a known drug therapy in the external treatment of Traditional Chinese Medicine. It has the characteristics of high safety, small side effects, and high acceptance. In the future, our laboratory will continue to conduct the key research on the mechanism and the clinical efficiency of TCM treatment of brain diseases, such as cerebral palsy, stroke, and so on.
[Narrator] To begin, place the anesthetized infant rat under a dissecting microscope. Cut the skin of the left neck, and using ophthalmic scissors, bluntly separate the sternohyoid muscle and the left sternocleidomastoid muscle. Then, identify and separate the left common carotid artery and vagus nerve. For the model group, use an electric coagulation pen to cut off the left common carotid artery. Then, clean and suture the neck incision. After inducing hypoxia, remove the rat from the hypoxia box and place it in the prone position in a box with normal atmospheric oxygen content. Place the box in a 37 degree Celsius thermostatic water bath for one hour before transferring the rat back to its mother cage. After modeling, carefully hold the infant rat with cerebral palsy in the palm of the left hand, bend the left thumb, and with the help of the right index and middle fingers, cover the eyes for two minutes to form a dark field of vision. Place the rat in the prone position, ensuring the spine is straight. Using the right index finger, middle finger, and ring finger, make a circular rubbing motion on the cervical, thoracic, and lumbar spine from head to tail 100 to 200 times for one minute without disturbing the subcutaneous tissue. Next, perform circular motion on the trapezius, superficial gluteus, cervical rhomboid, pectoral rhomboid, latissimus dorsi, and external oblique muscles in order from head to tail according to the animal anatomical standard without disturbing the subcutaneous tissue. Using the right index or middle fingers, performs circular kneading on the cervical, thoracic, and lumbar vertebrae combined with downward pressing for five minutes at a frequency of 120 times per minute. Press the skin surface of the trapezius, superficial gluteus, rhomboid neck, rhomboid pectorals, latissimus dorsi, and external oblique abdominal muscles for five minutes in a round kneading motion from head to tail. Next, perform a circular kneading and downward pressing on the sensitive spinal acupoints at a frequency of 100 to 120 times per minute for two minutes. With the right thumb and index finger, gently pinch the affected limb, ensuring symmetrical force on the two fingers. Rub the right extensor carpi radialus, extensor digitorum communis, extensor carpi ulnaris phalanx, interphalangeal joint, gastrocnemius muscle, semitendinosus muscle, metatarsal bone, and intermetatarsal joint back and forth. Apply the rubbing method along an imaginary line from the forehead to the middle of the posterior brain 100 to 120 times for one minute.
