Trigger Point Pain, Myofascial
Conditions
Brief summary
This study would be the first study to assess the immediate effects of dry needling of latent trigger points of the gastrocnemius muscle on muscle stiffness, gait, range of motion, and strength. The study has the potential to demonstrate that dry needling may have immediate effects on mechanical properties of muscle and may thus guide future treatment for individuals with changes in muscle tissue secondary to pain and/or injury.
Detailed description
Participants will complete the following tests: muscle stiffness testing in both a relaxed and contracted position, GAITRite for spatial and temporal gait characteristics, the Ankle Lunge Test (ALT) to assess range of motion, and calf strength using a dynamometer. Subjects will then receive treatment according to which group they are randomized. Muscle stiffness, gait, motion and strength will be reassessed immediately following treatment at the first session. Four to10 days later, participants will complete the same tests and measures prior to treatment being administered a second time. Another 4-10 days after the second session, participants will complete the tests and measures one final time.
Interventions
OTHERDry Needling
Individuals randomized to the Dry Needling Group will receive dry needling to latent trigger points of the gastrocnemius muscle
OTHERSham Dry Needlling
Individuals randomized to the Control group will receive sham needling to the gastrocnemius muscle

Inclusion criteria
1. Age 18-50 years 2. Able to read and speak sufficient English to complete consent form 3. Symmetrical gait pattern demonstrated through observation 4. Presence of latent trigger point in gastrocnemius muscle
Exclusion criteria
1. Any prior foot/ankle surgery, deformity, or injury on the which would affect strength of the gastrocnemius 2. Any prior acupuncture or dry needling within the past month 3. History of systemic disorder in which dry needling would be contraindicated (i.e. bleeding disorders or anticoagulant medication use) 4. Have fractures of the spine, hip, or knee that would likely affect their weight bearing or gait 5. Restrictions in plantar flexion range of motion which would inhibit performing a heel raise 6. No specific calf injury in the past 6 months 7. Participants known or thought to be pregnant
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| MyotonPRO | 2 years | Muscle stiffness will be measured in both a resting and contracted state utilizing this non-invasive device |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Knee to wall | 2 years | Group by time differences will be assessed for talocrural motion (knee to wall) |
| GAITRite | 2 years | Group by time differences will be assessed for gait variables (utilizing the GAITRite 6-meter mat) |
| Handheld dynamometer | 2 years | Group by time differences will be assessed for strength of the gastrosoleus complex (utilizing a handheld dynamometer) |
