Comparison of the Immediate and Delayed Effects of Two Methods of Fast in fast out and Winding Dry needling in Gastrocnemius Muscle Trigger Points on Lower Extremity Function and Pain in Non-professional Athletes

Comparison of the immediate and delayed effects of two methods of fast in fast out and winding dry needling in Gastrocnemius muscle trigger points on lower extremity function and pain in non-professional athletes

One blind clinical trial will performed on two groups including control group with needles in a piston method, and the second group in a needle rotation method, which was randomized with software. Sample size will be 60 subjects.

Participants will be male athletes at the level of the sports clubs and sports teams of Semnan, who will have Gastrocnemius muscles trigger points . participants are divided into two groups which are blinded to other group. The groups will treated with two needle techniques. The jumping height will measured by the camera of motion analysis at the intervals before and after the treatment, at intervals of 24, 48, 72 hours and four weeks after treatment. The intensity of the pain will also measured based on the visual analog scale of pain before, during treatment, after treatment, and 24, 48, 72 hours, four weeks after treatment.

subjects will selected by examination. The presence of fibrous bundles in the muscle, sensitivity to touch, the presence of palpable or visible muscle fasciculation in the palpation and pain in posterior region of the leg while walking or running without morning symptoms that can be radicular or constant. Participants should have moderate pain intensity and based on the visual scale, the pain should be between 3 and 6. They should be athletes and running, jumping, abrupt change, fast running should be main component of their sports.they should have training at least two days a week.

Individuals will divided into two groups. fast in fast out group and winding needling group

Pain and jumping height will be evaluated.

To ensure that two groups are matched in terms of sex as well as to achieve a complete randomized and balanced assignment, we will use stratified randomization method (layered) by stratified permuted block randomization. So individuals are divided into two stratum of male and female and for each stratum, a separate random assignment is continued until the optimal sample size is reached. For a random assignment in each stratum based on the sequences of the two methods A and B, six blocks are defined as follows and numbered from 1 to 6 respectively: AABB- BBAA- ABAB- ABBA- BABA- BAAB Then, blocks of random numbers are randomly selected by numbers 1 to 6. (numbers 0 and 7 to 9 are not the criteria for the decision). Thus, the type of intervention for each five people is determined respectively. Random allocation software will be used to construct the encryption tag, and then we will use the enclosed packet to hide it randomly.

In order to blind the participants, the details of technique will not be explained for them and only the explanation of trigger points treatment by needling will be clarified. Also the individuals of each group will not be informed of the existence of the other group, to achieve this purpose, two groups will be visited on different days to get treatment and record jumping.
