| Study group | Role | What they receive |
|---|---|---|

What is being measured
The primary outcome is the main question the study is designed to answer.
sensation
Sensory disturbance were tested with Semmes-Weinstein filaments and sensory deficits were categorized according to the Yale sensory scale. According to standard scoring system that designed, the severity of sensation and function of the ulnar nerve was scored as follows: ---- 0, Abscent sensation; 1, Decrease or abnormal sensation; 2, Intact sensation.
Measured: at 6 months post-operatively
Secondary outcomes (3)
Muscle strength
Muscle strength was evaluated with the grading system from the Medical Research Council which is based upon a scale of zero to five: 0, No muscle contraction; 1,Flicker or trace of muscle contraction; 2,Limb or joint movement possible only with gravity eliminated; 3,Limb or joint movement against gravity only; 4,Power decreased but limb or joint movement possible against resistance; 5,Normal power against resistance. Then results were scored as follows: ---- 0,Poor (0-1); 1,Moderate (2-3); 2,Good (4-5)
Measured: at 6 months post-operatively
pain
Visual Analogue Scale (VAS) with scores of zero to ten (0 for no pain and 10 intolerable pain) then scored as follows: ---- 0, Sever (8-10); 1, Slight (4-7); 2, none (0-3)
Measured: at 6 months post-operatively
electromyography
Compare the result at 6 months post-operatively with the result before operation.To see if there is an improvement in the function of the ulnar nerve.0,no improvement;1,improvement.
Measured: at 6 months post-operatively

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 8 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
sensation (time frame: at 6 months post-operatively). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
