Shoulder Pain
Conditions
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.
Interventions
OTHERQuantitative Sensory Testing
Participants will undergo heat pain threshold, cold pain threshold, pressure pain threshold, temporal summation, and conditioned pain modulation to characterize pain sensitivity.
OTHERPain-Related Psychological Factors
Participants will complete psychological questionnaires to characterize these factors.

Inclusion criteria
* shoulder pain symptom intensity rated as 3/10 or higher in the past 24 hours * attending physical therapy for shoulder pain
Exclusion criteria
* non-English speaking * systemic medical conditions that affect sensation, such as uncontrolled diabetes * history of shoulder surgery or fracture within the past 6 months * history of a chronic pain condition, such as fibromyalgia * blood clotting disorder, such as hemophilia * contraindication to the application of ice (blood pressure \> 140/90 mmHg, cold urticaria, cryoglobulinemia, paroxysmal cold hemoglobinuria, circulatory compromise) * currently pregnant
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Heat pain Threshold | 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 | 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 | 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. |
