Inclusion criteria
* Individuals must present with decreased dorsiflexion measurement during screening of 35° or less unilaterally or bilaterally based on the weight bearing lunge test
Exclusion criteria
* Current and/or historical lower extremity injury or surgery within the last six months * Musculoskeletal or neurological disorders that could impact balance or normal lower extremity function * Extreme phobia of needles * On blood thinners * Chance of pregnancy * Known problems with immune system, * Presence of diseases or infections that can be spread through bodily fluids
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Peak ankle dorsiflexion | Pre-post testing on the same day. Post testing will occur within 60 minutes of the intervention. | The maximum amount of ankle forward bending during the movement. Measured in degrees using both inclinometry and motion capture-based relative segment angles in 3D.. |
| Peak ground reaction force | Pre-post testing on the same day. Post testing will occur within 60 minutes of the intervention. | The maximum amount of propulsive force measured by a 3D force platform during the movement. Measured in Newtons. |
| Peak muscle activation | Pre-post testing on the same day. Post testing will occur within 60 minutes of the intervention. | The maximum amount of electrical excitation of the soleus muscle during the movement. Measured in mV using surface electromyography. |
| Tissue stiffness | Pre-post testing on the same day. Post testing will occur within 60 minutes of the intervention. | A measure of the tissue compliance or stiffness of the soleus muscle. Measured in kPa using ultrasound-based shear wave elastography. |
