The aim of this study is to develop a novel quantitative metric for assessing upper-limb function in patients with neurological disorders. This will be accomplished by analyzing performance data obtained from a smart board and smart glove system and comparing these data with conventional clinical assessment methods currently used to evaluate upper-limb impairment.

Inclusion Criteria:

• Adults aged 19 years or older.
• Patients with upper-limb functional impairment due to neurological conditions such as stroke, cerebral palsy, brain tumor, traumatic brain injury, or Parkinson's disease.

Exclusion Criteria:

• Patients with progressive neurological disorders or those in a state of hemodynamic instability.
• Patients with severe cognitive impairment (MMSE < 10) or significant communication difficulty due to language disorders.
• Any other condition in which the investigator determines that participation in the study is inappropriate.
