Postural Control and Balance

Postural Control and Balance:

Cerebral palsy mainly affects a child’s ability to move and the foremost reason contributing to this deficit is poor balance and postural control. Impaired postural control limits a child’s ability to recuperate from unforeseen threats to body stability, referred to as sensitive balance control. Impaired postural control in children with CP has been revealed to result from several factors: musculoskeletal complications, including muscle contractures, diminished range of motion, and changes in initial position, all disturb the sensitive balance mechanism in children with CP. Additional movement components comprise the disturbance of the spatio-temporal characteristics of postural muscle reactions during the recovery of stability subsequent an unforeseen external agitation. The start of postural muscle movement in children with CP is late when matched with typically developing children. In addition, the sequencing of several muscle activity is reduced and there is a high level of coactivation of agonist and antagonist muscles at joints in the body. Difficulty in establishing redundant sensory signals for balance control is another source of instability in children with CP.

Sitting Balance:

Improving postural control, and in specific sitting ability, is an significant feature of a child’s rehabilitation which can result in better well-being, functional ability and physical independence and a fall in the risk of contractures, deformity and foot ulcers. One method of trying to increase sitting ability is through the use of training exercises. It has been accepted that nonconcrete training tasks alone cannot give a whole image of the child’s ability and that treatments need to be based on a meaningful tasks to have the finest outcomes.

Very little has been researched on the efficiency of such therapies for improving balance control in children with cerebral palsy during sitting. Children were provided with the Wii Balance Board that detects movement of the center of pressure. Once connected to a computer the balance board could be used to control movement on the computer. The platform was used with various games such as Accelerate (Figure 1.12) and Numbers (Figure 1.13) to perform a number of activities. The children needed to change their center of pressure through trunk travels while sitting on the balance board.

Virtual Romberg Test

Researchers have exposed a diminished ability in children with CP to adjust the sensory and motor constituents of balance control to varying task and environmental loads. These balance control impairments disturb the skill of children with CP to respond to extortion's to balance efficiently and effectively. Thus it is important to have a simple and efficient to assess static and dynamic balance as like a VIHBRA-Virtual Romberg Test

Standing Balance:

Standing balance is the conservation of upright position during whole body movement over an altering base of support. This contains mostly of keeping the body’s center of mass within the base of support. Children with cerebral palsy do not have the bonus of usual growth and must contend with learning balance via the control of joints which have developed muscle contractures, deformities and others; all of which lead to the use of inimitable movement function adaptations in order to uphold dynamic stability. Within this domain, all activities developed were controlled with a Walnut Medical Balance Board (WMBB) linked to a computer via Bluetooth and Walnut Medical smart camera. The therapeutic benefits of those activities were already established and we elevated the benefits using our system.

Reach the Number: Person has been told to reach the particular number from 0 to 24 while standing in postural board.

VIHBRA Accelerate is the postural balance exercise game. User need to reach any particular level by putting pressure under left/right toes and heels.
