A Clinical Study On Treatment Of Tensile Pain Of Levator Scapulae Muscles' Attaching Points With Pi Needle

The levator scapula muscle is named for its function of scapular elevation. It is covered entirely by the trapezius muscle. It arises from the transverse processes of C1 through C4 and attaches on the vertebral border of the scapula between the superior angle and the spine. This muscle can aslo help maintianing the position of head when it's original point and attaching point are interconverting. The people who are often working in stting and bowing head position such as accountant, paperwork, and computer operator, etc. are easier to have harassment from chronic injuries of attaching points of neck muscles. Though being shoulder muscle, The attaching point of levator scapula muscle especially on its original point is also easy to get hurt caused by constant strain as it keeps bowing head for a long time.To objectively evaluate the clinical effect of Pi needle on cutaneous nerve entrapment syndrome (CNES),100 cases suffering from pains of the levator scapula muscle's attaching points were treated with Pi needle. There are 37 male and 63 female in 100 patients, age from 14 to 59 and the average is 35.72, the course of diseases from 3 to 7days and the average is 3.89 days. All cases came from Jiting medical care center in Malaysia were randomly divided into two groups, Pi needle and Hao needle therapy were applied to one group respectively. The results showed that the excellent ratio is 88.00% and the good ratio is 96.00% in Pi neddle group while 38.00% and 58.00% in Hao needle group. Statistic analysis to changing trends of symptom-signs score, Vas score, the value of compressive pain and local soft tissue tension showed there was a singnificant difference (P<0.05) between two groups at the level a= 0.05. The figure of data profile analysis suggested that the clinical effect of Pi needle group is much better than contral group. In following animal experiment,16 rabbits were used to evaluate the safety and validity of Pi needle therapy. The results supported the idea that Pi needle was more validity than Hao needle while less hruts than Zhen Dao (needle shaped bistoury).In the end, there is sufficient evidence that the Pi needle therapy is safety, ease, convenient, cheap, effective and provide a new therapy for the treatment of CNES.
