Clinical Trial Summary

The goal of this study is to investigate the effect of intramuscular dry needling (IMDN) on muscle stiffness and pain. Research has suggested that IMDN can reduce muscle stiffness in needled areas. As well, IMDN may reduce mechanical pain sensitivity experienced by individuals.

IMDN will be performed at several anatomical locations. Muscle stiffness will be measured with a handheld probe, which measures contact force and displacement of soft tissue. Pressure-pain thresholds (PPT) will be discovered at each region of interest. Stiffness and pressure-pain thresholds will be collected before and after IMDN. The data collected from this research is important to understand the mechanism of IMDN and its relationship to pain.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Effective stiffness of soft tissue	Force-displacement data is collected while deforming the soft tissue at the skin surface with a non-invasive handheld probe. The effective stiffness is a summary of the deformation behavior of the soft tissue. It is estimated using the force-displacement data as an input to the incompressible isotropic hyperelastic Ogden model. A higher value indicates that the soft tissue is stiffer than a lower value.

Primary	Pressure-pain threshold	The measured pressure at the moment the perception of pressure turns into pain	Within 10 minutes of intervention
