Brief Summary:
This study evaluates the effect of acupuncture on post-stroke overactive bladder symptoms. Participants will be put into groups randomly and compared. There are two groups: traditional acupuncture and usual care. The ratio of group allocation is 1:1.

Condition or disease Intervention/treatment Phase
Overactive Bladder Other: Traditional Acupuncture Other: Usual Care Not Applicable

Detailed Description:
Current practice in management of OAB is quite limited. Acupuncture, which is a major treatment modality of traditional Chinese medicine, has also claimed to have favourable therapeutic effect on OAB. Previous study found that acupuncture at the BL-33 point was effective for controlling the overactive bladder. Although acupuncture has been shown to be effective in treating OAB, there has been no randomized controlled trial examining the efficacy of acupuncture on patients with post-stroke. Given the high incidence of OAB in post-stroke patients, potentially effective alternative treatments should be investigated.

Arm Intervention/treatment
Experimental: Traditional Acupuncture
Acupoints which are empirical for treating OAB in terms of Traditional Chinese medicine theory are used (in the sequence of scalp reproduction area and motor area of the unaffected side, RN3, bilateral BL32, BL33, BL28, BL39). And Ear point urinary bladder, and Ear point uterus will be treated after removal of needles. Needles will be left for 30 minutes and then removed. Subjects will be treated with acupuncture 2 times per week for the first 2 weeks and 1 per week for the 3rd and 4th week.
Other: Traditional Acupuncture
Treatment is based on the traditional Chinese medicine theory for treating overactive bladder. Qi-transforming function of bladder is regulated by experienced Chinese medicine practitioner.

Usual Care
Patients will receive conventional rehabilitation as usual, including standard physiotherapy, bladder training and general advise of fluid intake.
Other: Usual Care
Patients will receive conventional rehabilitation as usual, including standard physiotherapy, bladder training and general advise of fluid intake.

Primary Outcome Measures :
  1. Overactive Bladder Symptom Scale (OABSS) [ Time Frame: 1-week posttreatment ]
    four item questionnaire quantifies overactive bladder symptoms in a single score

Secondary Outcome Measures :
  1. Number of incontinent episodes measured by bladder diary [ Time Frame: 1-week posttreatment, 4-week posttreatment ]
    Record the frequency of day and night time voiding and incontinence episodes over 3 day periods

  2. Stroke Specific Quality of Life Scale (SS-QoLS) [ Time Frame: 1-week posttreatment, 4-week posttreatment ]
    12 items questionnaire consists of physical and psychosocial subscales: amount of help required completing a task, trouble experienced performing a task and functioning.

  3. Medication measured by bladder diary [ Time Frame: 1-week posttreatment, 4-week posttreatment ]
    number of patients requested medication for OAB from bladder diary.

Other Outcome Measures:
  1. AE measured by open-ended questions [ Time Frame: first week of treatment, second week of treatment, third week of treatment, 1-week posttreatment, 4-week posttreatment ]
    open-ended questions about the experience of adverse events
