Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion criteria;

  1. patient with confirmed diagnosis of complete oculomotor nerve palsy (with or without mydriasis) made by neurologist or ophthalmologist;
  2. patient in stable condition after treatment for primary disease;
  3. age between 18 to 80 years old without gender limitation;
  4. haven't received acupuncture intervention for ONP before;
  5. patient with conscious, willing to cooperate and voluntarily agreed to participate and signed informed consent forms.

Exclusion criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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 oculomotor 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.

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 oculomotor 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Ocular motor nerve function subscale at 6 Weeks
Time Frame: 6 week
The patient will receive grading of eyelid lifting, eyeball inward, upward and downward moving ability by investigator. A total score will be summed up.The changes from baseline will be recorded.
6 week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Angle of diplopia deviation
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.
6 week
Eyeball movement distance
Time Frame: 6 week
The distances of eyeball movement in inward, upward and downward direction and height between eyelids will be measured. The differences between affected and healthy eye will be calculated.
6 week
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.
6 week
