NeuroDevelopmental Therapy in Cerebral Palsy

NDT is a technique to facilitate the movements which are not present in the Cerebral Palsy children.

Facilitation is a process in which therapist hand gives a direction to the child’s body how to move. In this technique therapist holds the complete control of child’s body weight and the movement. Therapist gives a direction to the body to shifts its COG (Center of Gravity). As the COG shifted to some direction the control over the balance in the child is lost. Therapist should teach the child how to gain control again, by shifting weight to another side. This whole procedure is the part of NDT.


Equipments used in the NDT are Ball, Bolster, or Table/Bench.

Equipments are to challenge the body weight, to help accommodation the structural deformities of the child. These facilitation techniques are used improve the postural control of the child by challenging the posture.

BOLSTER/ROOSTER: is devices which is used to for prone, sitting and sit to stand facilitating techniques. It should be firm, provides a mobile surface that is easy to control because it rolls predictably front to back when child lies prone or sit on it.

BALL: is the most challenging device for the facilitation techniques. It is not firm because it can move in any direction and the base of support is very less.
There are two type of cerebral palsy according to the tone, Hypertonic and Hypotonic. Facilitation is given according to the tone of child. Hypertonic child is given facilitation techniques to decrease its tone and to improve its posture. Hypotonic is given different facilitation to increase the tone and posture.
 

First of all we should check the child’s stage and milestones before taking in the NDT.

Neck holding is the first step which should come in the child if it is absent then just facilitate neck extensors to extend the neck. On bolster put child in prone then ask him to hold the neck in extension by facilitating trapezius muscle or taking the shoulders in retraction. On ball put child in creep/crawl positions then the same facilitation done. Facilitation on the spine can also be done to make spine in extension and neck in hold position.

Quadruped position is the next position attends by the child. In this weight bearing on all four limbs is essential. So the power on all four limb must be good. This posture is attended on the ball. We can make it more challenging by rolling the ball so that the COG of the child’s body shifts and the opposite muscles work to prevent a fall.

Pelvic control facilitation techniques can be done on the ball and bolster both. On the bolster we can make child sit and the roll the bolster to shift COG and facilitate muscles to prevent any fall. Like this we can make child sit on the ball and can move ball too to shift the base of support and facilitate muscles. On ball different positions can be attended like cross sitting, kneeling, sitting by legs open wide on ball, sitting and hands are extended and sitting with hand in overhead position. Rankly decrease base of support and increase pelvic control. In all these positions we can facilitate pelvic muscles by rolling ball, shifting base to either side, ask child to reach an object to either side, make base less supportive by tilting ball on opposite side. All these make the muscles work and repetition of this strengthen the muscles.



The main purpose of the NDT is to improve balance with less support. Facilitation technique is more effective then passive movements. Resistive exercises are difficult in cerebral palsy child because they are not so cooperative and not following commands. So the most effective technique is NDT in the cerebral palsy.

What are The Botulinum Toxin in Cerebral Palsy

Clinical use of botulinum was recognized by Bergen et al. in 1949 by identifying the effect of botulinum toxin on neuromuscular transmission. Once it was thought to be potent biological toxin to human body, now its potential is being utilized as therapeutic agent for different clinical problems specially spasticity & cosmetic purpose. In all variety of botulinum toxin, type A is used for the clinical application. This is being utilized in Mx of cerebral palsy since 20 years.

This toxin is used as intramuscular injection at most condensed site of neuromuscular junction of affected muscle. This toxin block acetylcholine release from neuromuscular junction & causes local temporary chemo-denervation and effect last for 4-6 month. Even after disappearance of drugs, some modulation of nerve transmission has been seen, so effect persist beyond the time limit and dystonic posture also get corrected due to slight diffusion of drugs in systemic manner.  It is being commonly used for spastic & dystonic cerebral palsy Treatment.


Cerebral Palsy Treatment

Dose & safety margin depends upon brand of botulinum toxin, number of muscle and wt of child. Total maximum dose is about 10-12 unit per Kg of body Wt. it is being used in all affected spastic muscles and usually at multiple site (3-4 in each muscle). 

Effect of botulinum toxin can be prolonged with post injection plaster, proper patient & muscle selection, injection under anesthesia and post injection braces and good therapeutic protocol. Plaster is given for only 7-10 days then patient is advised braces and therapy.


It is very effective when child have dynamic spasticity between the age group of 2-5 years and not so useful when child develop contracture and deformity. Botox injection is advisable when Spasticity is interfering in therapy programme and muscle excursion become too less.

Usually botulinum toxin injection are used in all affected muscle in a single setting and it is better to give it under anesthesia, because it require multiple injection puncture and is painful and it also save the toxin from wastage. Most commonly botulinum toxin is used in Gastrocnemius, Hamstring, Rectus Femoris, Adductor, Pronator Teres, and Flexor Digitorum.

Injection can be repeated every three monthly but if proper postoperative therapeutic protocol has been taken into consideration it may not be so frequent. At Samvedna, we rarely require repetition of toxin due to good therapeutic protocol and use of braces. It reduces pain, facilitate therapy, better cooperation of child, better functional and motor gain.

By the use of toxin, OSSCS Surgery also can be delayed till the maturity of gait. Antibodies to toxin have been one of the possible problems with repeated injection that can interfere in next injection of toxin.  Otherwise it is well tolerated. Side effects are very -2 rare.
