Weight distribution asymmetry in relation to walking speed in children with spastic cerebral palsy.

Background: Gait speed and postural stability are indicators of community level ambulation and may be a valuable measure of disability. Objectives: to investigate the relation between the distribution of weight on both lower extremities and gait speed in children with spastic cerebral palsy. Methods: Evaluation for weight distribution on both lower limbs and speed during gait for sixty children with spastic diplegia and forty-five children with hemiplegia was carried out by the Biodex gait trainer. Pearson correlation test was conducted to determine the relation of the symmetry index and the percent of weight bearing to speed. Results: A significant weak positive correlation was found between speed and symmetry index in diplegic group, while there was a non-significant weak negative correlation between speed and symmetry index was noticed in hemiplegic group. Nonsignificant weak positive correlation between speed and weight on most affected side was recorded in diplegic group. While in hemiplegic group, there was significant weak negative correlation between weight on affected side and speed. Conclusion: Children with cerebral palsy demonstrate asymmetrical weight distribution during walking. Physical therapy training should be directed to enhance weight bearing distribution thus improving gait and postural stability.

Gait Rehabilitation in Ambulant Diplegic Children Using Botulinum A Injection and Ankle Weights.

Objectives: Standing and walking serve an individual's basic needs to move from place to place, and both are the most common activities that people do daily. So, this study aims to investigate the combined effect of botulinum A injection and ankle weight on excessive knee flexion in diplegic children with crouch gait. Methods: Sixty children with spastic diplegia walking with a crouch gait were included in this study. They were divided equally into three groups (twenty in each): group A received classical gait rehabilitation, group B received the same gait training while adding ankle weights, and group C received the same as group A and B plus botulinum A injection. The modified Ashworth scale (MAS) and Hoffman reflex/Myogenic response (H/M ratio) were used to evaluate the spasticity of the hamstring and gastrocnemius muscles, while two-dimension gait analysis was used to record knee flexion angles during gait. The assessment was held one day before starting the treatment and after completing three months of the treatment program. Results: There was no significant difference between groups before treatment regarding all measured variables. group A revealed a statistically nonsignificant improvement after treatment. Patients in group B showed significant improvement after treatment for both knees regarding the H/M ratio and MAS, which was reflected in the right and left knee range of motion at initial contact (P values 0.030 and 0.001, respectively) and midstance (P values 0.030 and 0.006, respectively). However, more significant improvement was detected regarding all studied variables in both knees after treatment in group C patients with a P value <0.001. Conclusion: The combination of botulinum A injection and ankle weights was more effective in controlling excessive knee flexion in diplegic children with a crouch gait.
