Core Stability in Ataxic Cerebral Palsied Children

Overview

Forty children with cerebellar ataxia ranged in age from five to nine years old, they were randomly assigned into two matched control and study groups. The control groups received the selected physical therapy program three times weekly one hour per session while the study group received core stability training for 30 minutes in addition to the selected physical therapy program. Both groups were evaluated by SARA Scale for the Assessment and Rating of Ataxia, Balance Error Scoring Systems scale, Bruininks-Oseretsky test of motor Proficiency 2ed subtest 4 (bilateral coordination), and subtest 7 (upper limb coordination), and HUMAC Balance System before and after two months of intervention.

Forty ataxic cerebral palsied children were selected from private pediatric physical therapy centers, their ages ranged from five to nine years old. They were simply randomly assigned into two matched control and study group via an electronic program (SPSS) as illustrated in figure (1). The selected children had level IV according to the gross motor function classification system and their ataxia severity score was less than 25 according to the scale for the Assessment and Rating of Ataxia (SARA). Children have excluded it they had visual impairment, spasticity, uncontrolled convulsions, any other neuromuscular diseases, ataxia-telangiectasia, spinocerebellar ataxia, and Joubert syndrome. Measures 1. Scale for the Assessment and Rating of Ataxia (SARA): it is a clinical scale that assesses a range of different impairments in cerebellar ataxia. The scale is made up of 8 items related to gait, stance, sitting, speech, finger-chase test, nose-finger test, fast alternating movements, and heel-shin test \[22\]. 2. Balance Error Scoring Systems scale (BESS): This tool assesses postural control in stable surfaces the tests performed on the ground and foam block. It composes of six items performed with eyes closed taking 20 Sc each \[23\]. 3. The Bruininks-Oseretsky Test of Motor Proficiency 2ed (BOT-2): It is a standardized, norm-referenced measure used by physical therapists and occupational therapists in the clinic and school practice settings. It is an individually administered test that delivers a most precise measure of motor skills, both gross and fine, of children and youth, 4 through 21 years of age \[24\]. 4. HUMAC Balance System: Developed by Computer Sports Medicine, Inc. (CSMi), The HUMAC Balance System is a high-quality computerized balance system. It is a static force plate (Force Plate Mode) that measures Center of Pressure (COP) and Force \[25\]. 1- Procedures for evaluation Both groups were evaluated before and after two months of intervention by the SARA Scale for the Assessment and Rating of Ataxia, Balance Error Scoring Systems scale, Bruininks-Oseretsky test of motor Proficiency 2ed subtest 4 (bilateral coordination) and subtest 7 (upper limb coordination), and HUMAC Balance System. 2- Procedure for intervention The Control group received the selected physical therapy program for one hour, three times weekly for two successive months including facilitation of balance and protective reactions from kneeling, half kneeling and standing position, standing alone on balance board, standing on one leg, open gait training alone (walking on the balance beam, walking on the stepper and walking on wedges), training stair climbing, and strengthening of the back and abdominal muscles. The study group received the selected physical therapy program for one hour, three times weekly in addition to core stability training program for 30 minutes \[26\].
