Cerebral palsy (CP) is characterized by many problems related to brain damage. One of these is sensory impairment. Sensory impairments in CP patients can also occur together with motor functions. Detecting sensory impairments (two-point discrimination, vibration, joint position sense, thermal sensation, stereognosis, graphesthesia) in the arm, forearm, and hand (upper extremity) in CP patients and investigating their relationship with motor functions is important. The aim of this research is to investigate the relationship between upper extremity sensory impairments and motor functions in patients diagnosed with unilateral (affecting one half of the body) CP.
