Medical students are prone to developing neck pain due to prolonged studying and poor posture. This can manifest as tender points in the upper trapezius region. Counterstrain (CS) is an osteopathic manipulative technique that has shown efficacy in previous studies in treating tender points. The MyotonPRO is a myotonometric device that can be used to measure various muscle parameters such as muscle stiffness. There is limited research regarding the use of osteopathic manipulative medicine to produce measurable changes in muscle stiffness by the MyotonPRO. This educational study aims to establish the efficacy of CS technique in decreasing the pain level of upper trapezius tender points in medical students as well as determining if CS causes a significant decrease in muscle stiffness in treated tender points as measured by the MyotonPRO. The investigators hope this educational study will encourage further studies on how osteopathic manipulative techniques affects the physiologic parameters of muscles.

Inclusion Criteria:

• Subject is at least 18 years of age

Exclusion Criteria:

• Traumatized (sprained or strained) tissues, which would be negatively affected by the positioning of the patient
• Illness or other conditions in which strict positional restrictions preclude treatment
• Instability of the area being positioned that has the potential to produce unwanted neurologic or vascular side effects
• Vascular or neurologic syndromes, such as basilar insufficiency or neural foraminal compromise whereby the position of treatment has the potential to exacerbate the condition
• Severe degenerative spondylosis with local fusion and no motion at the level where treatment positioning would normally take place
• Pregnancy
• Positive for COVID-19 as well as symptoms indicating a SARS-CoV-2 infection

The participant felt which side was being treated however, the investigator measuring the physiologic parameters of the muscle with the MyotonPRO was blinded in terms of what side was being treated.
