Brief Summary:
The purpose of the study is to testify the efficacy of treating trochlear nerve palsy with ocular electroacupuncture or ocular acupuncture, and to compare the efficacy between these two interventions.

Condition or disease Intervention/treatment Phase
Trochlear Nerve Palsy Other: ocular electroacupuncture Other: ocular acupuncture Other: sham acupuncture Not Applicable

Detailed Description:
The purpose of the study is to testify whether ocular electroacupuncture or ocular acupuncture is effective for trochlear nerve palsy (TNP), through treating TNP patient for 6 weeks, using self-invented acupoints according to anatomy of extraocular muscles innervated by trochlear nerve, and using sham acupuncture as controlled group, and try to provide clinical evidence for promoting these new techniques.

Arm Intervention/treatment
Experimental: ocular electroacupuncture
Patients will receive electroacupuncture for 40 mins with certain parameter at ocular area, once daily, 5 times a week and 6 weeks in all. The acupoints are selected based on the anatomy of extraocular muscles innervated by trochlear nerve.
Other: ocular electroacupuncture
During intervention period, patients will continue to keep medications for primary condition. Patient's skin located in the extraocular muscles projection area is routinely disinfected. A diameter of 0.20 mm and length of 25 mm needle is inserted slowly. Piercing depth is about 20mm. The electropuncture apparatus is used, each group of electrodes are distinguished with different colors of wires to generate current stimulations of current 1.0~1.5 milliampere (mA), voltage 9 volt(V), frequency 1.5 hertz (Hz), and duration of 40 minutes.

A diameter of 0.20 mm and length of 25 mm needle is inserted slowly. Piercing depth is about 20mm.The duration of intervention is 40 minutes.

Sham Comparator: sham acupuncture
Patients will receive sham acupuncture for 40 mins at ocular area, once daily, 5 times a week and 6 weeks in all. The acupoints are selected based on the anatomy of extraocular muscles innervated by trochlear nerve. When the care provider performed operating acupuncture, the needles of sham acupuncture set will not be inserted into the skin of patient.
Other: sham acupuncture
During intervention period, patients will continue to keep medications for primary condition. Patient's skin located in the extraocular muscles projection area is routinely disinfected. A diameter of 0.20 mm and length of 25 mm sham needle set is stick onto insertion area without piercing into the skin. The duration of intervention is 40 minutes.




Primary Outcome Measures :
  1. Change from Baseline in Angle of diplopia deviation at 6 Weeks [ Time Frame: 6 week ]
    Patients will receive computerized diplopia test with the guidance from an investigator. The data will be generated by the software automatically. The changes from baseline will be recorded.


Secondary Outcome Measures :
  1. The quality of life questionnaire for ocular motor nerve palsy [ Time Frame: 6 week ]
    The patients will finish a questionnaire to evaluate their physical and psychological status during this trial.
