Brief Summary

The purpose of this study is to see the impact of a modified Spencer's technique on tissue stiffness, mobility, and blood flow of the shoulder joint. Spencer's technique is a well-known osteopathic manipulative treatment (OMT) that is common for treating adhesive capsulitis and is believed to help blood flow. There are studies that look at the clinical effects of the technique and/or compare it to other techniques; however, measuring the extent to which Spencer's technique, or this modified technique, improves tissue stiffness and blood flow has never been written in the literature. This study will serve as a proof of concept that this technique improves tissue stiffness, blood flow, and mobility of the shoulder join as well as the nearby areas. Using ultrasound, the investigators will measure tissue stiffness and blood flow and will analyze the mobility of the shoulder joint using a Vicon motion capture system.

Arm && Interventions

Group	Intervention	Description
Rest, then OMT Intervention	Osteopathic Manipulative Treatment-Spencer's Technique (Modified)	10 subjects will be randomized to begin with the non-dominant shoulder. Investigators will measure baseline outcomes on the non-dominant shoulder, a rest period equivalent to the time needed for OMT treatment, measure post treatment outcomes on non-dominant shoulder, a 5-minute rest period as a washout period, then proceed to measure baseline measures on dominant shoulder, provide OMT treatment, ending with post measurements on the dominant shoulder.
Rest, then OMT Intervention	Rest	10 subjects will be randomized to begin with the non-dominant shoulder. Investigators will measure baseline outcomes on the non-dominant shoulder, a rest period equivalent to the time needed for OMT treatment, measure post treatment outcomes on non-dominant shoulder, a 5-minute rest period as a washout period, then proceed to measure baseline measures on dominant shoulder, provide OMT treatment, ending with post measurements on the dominant shoulder.
OMT Intervention, then Rest	Osteopathic Manipulative Treatment-Spencer's Technique (Modified)	10 subjects will be randomized to begin with the dominant shoulder. Investigators will measure baseline outcomes on the dominant shoulder, apply OMT treatment, measure post treatment outcomes on dominant shoulder, a 5-minute rest period as a washout period, then proceed to measure baseline measures on non-dominant shoulder, a rest that is equivalent to the time needed for OMT treatment, ending with post measurements on the non-dominant shoulder.

Primary Outcome Measures

Name	Time	Method
Muscle Stiffness	Day 1 Pre, Day 1 Post, Day 2	Using Shear Wave Elastography to measure muscle stiffness (kPa) of the supraspinatus, infraspinatus, posterior shoulder capsule, and coracoacromial ligament.
Microvascular/capillary blood flow	Day 1 Pre, Day 1 Post, Day 2	Using ultrasound to capture blood flow of the supraspinatus, infraspinatus, posterior shoulder capsule, and coracoacromial ligament.
Shoulder Mobility	Day 1 Pre, Day 1 Post, Day 2	Using Vicon motion capture system to calculate landmark coordinates and using morphometric canonical variate analysis to analyze mobility changes.
Subjective Shoulder Stiffness (Visual Analogue Scale)	Day 1 Pre, Day 2	Using Visual Analogue scale to measure participant's subjective measure of shoulder stiffness. Scores range from 0 to 10, with 0 being "Not stiff at all" and 10 being "Very stiff."
