Hello,
I saw ur posting now only. You have to see whether it is a sensory ataxia or cerebellar ataxia.
If it is a sensory ataxia, gait training in parallel bars in front of mirror to compensate for poor sensory feedback is useful. Frenkel coordination ex's are valuable.
If the muscles are weak, weightbearing activities for upper and lower limbs with therapist assistance can be tried. PNF, rhythmic stabilization for proximal joints is also a useful tool
