The study is to examine the effect of functional trunk training on trunk control and upper extremity functions in patients with autosomal recessive ataxia.

Hereditary ataxias are a group of genetic diseases characterized by slow progressive gait disturbance. In addition, coordination disorders can be seen in extremities, speech and eye movements. Atrophy is common in the cerebellum. Friedreich's ataxia, ataxia telangiectasia, ataxia with vitamin E deficiency, infantile-onset spinocerebellar atrophy and Marinesco-Sjögren syndrome are autosomal recessive hereditary ataxias. The constant main sign of autosomal recessive ataxia is progressive ataxia.

The trunk has an important role on dynamic stabilization for postural reactions and limb movements. A good trunk support enables movements in other parts of the body to occur more regularly. Trunk stabilization is important to support upper and lower extremity movements, to meet the loads, and to protect the spinal cord. The relationship between upper extremity function, daily living activities and trunk functions has been emphasized in many studies but comparative studies about the rehabilitation were very less.

This study is to evaluate the effect o functional trunk training in patients with autosomal recessive ataxia.
