Overview
Brief Summary
Irritability was defined by Geoffrey Maitland as the vigor of activity to provoke symptoms, the severity of symptoms, and time for symptoms to subside. Irritability is deeply embedded in the physical therapy clinical decision-making process. However, the mechanisms contributing to irritability are unknown. Therefore, the purpose of this study is to characterize pain sensitivity and pain-related psychological factors by irritability level in individuals with shoulder pain.

Outcomes
Primary Outcomes
Heat pain Threshold
Time Frame: Day 1
A thermode will be applied to the deltoid, tibialis anterior, and lower back. The thermode will gradually increase temperature until the sensation changes from comfortable warmth to pain (pain threshold). Once pain threshold is reached, the temperature in degrees Celsius for heat pain threshold is recorded.
Cold Pain Threshold
Time Frame: Day 1
A thermode will be applied to the deltoid, tibialis anterior, and lower back. The thermode will gradually decrease temperature until the sensation changes from comfortable cold to pain (pain threshold). Once pain threshold is reached, the temperature in degrees Celsius for cold pain threshold is recorded.
Pressure Pain Threshold
Time Frame: Day 1
An algometer will be applied to the deltoid, tibialis anterior, and lower back. Pressure will be gradually applied until the sensation changes from comfortable pressure to pain (pain threshold). Once pain threshold is reached, the pressure in kilopascals will be recorded for pressure pain threshold.
