Primary Outcome Measures :
  1. Activities of daily living (ADL) scores [ Time Frame: 9 months ]
    ADL is commonly utilized to indicate the patient's functioning condition and level of care assistance by the Hospital Authority in Hong Kong.

Secondary Outcome Measures :
  1. Mini-mental state examination (MMSE) [ Time Frame: 9 months ]
    The MMSE test is a standard tool for cognitive assessment in the clinical setting. It is a 10-minute bedside measure of impaired thinking in undeveloped, uneducated, diseased, or very old populations. The summed score of the individual items indicates the current severity of cognitive impairment.

  2. Traditional Chinese Medicine Syndrome Score Scale (TCMSSS) [ Time Frame: 9 months ]
    The TCMSSS is based on <Criteria for diagnosis and curative effect evaluation of stroke>. Total scores range from 0 to 52, with scores above 40 indicating very severe neurological impairment, scores of 14 to 39 suggesting moderately severe to severe impairment, and scores below 13 indicating mild impairment.

  3. Constitution in Chinese Medicine Questionnaire (CCMQ) [ Time Frame: 9 months ]
    The CCMQ is applied to evaluate body constitution of each patient by score (Balanced Constitution, Qi-deficient Constitution, Yang-deficient Constitution, Yin-deficient Constitution, Phlegm-dampness Constitution, Damp-heat Constitution, Stagnant Blood Constitution, Stagnant Qi Constitution, and Inherited Special Constitution).
