Clinical Trial 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.


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.

Intervention

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.
ocular acupuncture
