Myofascial Pain, Neck Pain, Shoulder Pain
Conditions
Brief summary
Participants will be 18-59 years old who are recruited through a convenience sample from the UMHB/Belton community. There will be a randomized control trial consisting of three groups. Each participant will be assigned based on their order of entry to the study group assignment and then randomly organized via computer generation into 3 groups of 20 participants including a control group, a dry needling group (DN), and a dry needling E-stim group (DN-ES), resulting in approximately 60 total participants. Participants in the DN and DN-ES groups will be treated four times; at weeks 0, 2, 4 and 6 of the study. Data will be collected at weeks 4, 6 and 12 in all groups.
Detailed description
Interventions per group: Control: none DN: 20-30 seconds of DN per trigger point in each involved trapezius muscle, needles rest in situ 10 min, needles removed. DN-ES: 20-30 seconds of DN per trigger point (TrP) in each involved trapezius muscle, DC ES attached to needles crossing the most reactive TrP and current set to strong, but comfortable intensity at 10 MHz for 10 min, needles removed.
Interventions
PROCEDUREDry Needling (DN)
One to three filament needles (similar to an acupuncture needle) with no medication will be inserted into the trigger point(s) of the muscle. The needles will be repositioned a few times to make the muscle twitch (local twitch response). After several twitches occur, the researcher will leave the needles as they are, and the subject will lie on a treatment table without moving arms or head, for 10 minutes. After 10 minutes the needles are removed and discarded.

The needles will be repositioned a few times to make the muscle twitch (local twitch response). After several twitches occur, the researcher will leave the needles as they are, and attach alligator clips to the needles to provide electrical stimulus for 10 minutes while the subject lies on a treatment table without moving arms or head. After 10 minutes, the electrical stimulus will be turned off and detached, and the needles removed and discarded.

Intervention model description
Experimental There will be three groups in this study; control, DN alone and DN/IES. Each group will have approximately 20 subjects, resulting in approximately 60 subjects total. Subjects will be randomized into one of the three groups via block randomization method based on order of entry into the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in numerical pain rating scale (NPRS)between groups | 6 weeks | Between group difference in within group pain changes. The NPRS is an 11 point (0-10) scale with 10 meaning the worst imaginable pain and 0 meaning no pain. It is reported as a whole number out of 10, and multiple ratings, i.e. worst, average, and best pain scores over the past 48 hours, can be averaged and reported as a single score. |
| Change in Neck Disability Index (NDI) | 6 weeks | Between group difference in within group disability changes. The NDI is a questionnaire with 10 items including personal care, pain, reading, lifting, headaches, concentration, sleeping, work, driving, and recreation. Each section is scored on a 0 to 5 rating scale. Zero means 'No pain' and 5 means 'Worst imaginable pain'. Al the points can be summed to a total score. The test can be reported as a raw score, with a maximum score of 50, or as a percentage. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Maintenance of improvement in pain scores (NPRS) | Compare 6 week data to 12 week data | Difference between pain scores in both groups between the 6th week of weekly treatment and those 6 weeks after cessation of treatment. Scale is 11 points (0-10) with 10 being the Analysis of within group pain scores. The NPRS is an 11 point (0-10) scale with 10 meaning the worst imaginable pain and 0 meaning no pain.
