Effect of Cooling Therapy for Post-Operative Pain in Open Carpal Tunnel Release

Study Overview
=================
Brief Summary
-----------------
This study seeks to perform an appropriately-powered study to evaluate any clinical difference between continuous cooling therapy and traditional ice for treatment of post-operative pain in open CTR surgery.

Detailed Description
-----------------
Post-operative pain control is paramount to all operative procedures and involves several modalities. Both pharmaceutical and non-pharmaceutical measures are frequently used. Carpal tunnel release (CTR) surgery is one of the most common surgeries performed in the U.S. with over 400,000 procedures per year.2 Frequently, ice is used as a treatment modality following surgical CTR.3 Several products have been developed in the past decades to improve ice therapy in the rehabilitation period. One such product is the Polar Care which provides up to 6-8 hours of continuous icing. While there is good data supporting the use of cooling therapy (ice) for post-operative pain, there is lack of data surrounding the use of continuous cooling therapy machines such as the PolarCare following carpal tunnel release (CTR). The two papers that evaluated the efficacy of continuous cooling therapy following CTR had conflicting results on any added benefit of continuous cooling therapy over traditional icing. There is no standard of care for post-operative icing at UCMC following CTR. Clinicians currently decide whether to give patients a PolarCare machine on the day of surgery without any algorithm. All other patients are encouraged to use traditional icing methods. This study seeks to perform an appropriately-powered study to evaluate any clinical difference between continuous cooling therapy and traditional ice for treatment of post-operative pain in open CTR surgery. The investigators hypothesize that participants receiving continuous cooling therapy will have a statistically significantly lower pain score compared to those receiving traditional ice therapy.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental Ice Therapy<br>Postoperative care with experimental ice therapy | Other: Polarcare Machine<br>* Use of Polar Care ice machine as often as possible, but a minimum of three 15 minute uses per day, for the first 3 days after surgery.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual Analog Scale (VAS) for pain | The visual analog scale for pain is a straight line with one end meaning no pain and the other end meaning the worst pain imaginable. A patient marks a point on the line that matches the amount of pain he or she feels. | 3 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Disabilities of the Arm, Shoulder, and Hand questionnaire | he DASH is a 30-item self-report questionnaire designed to assess musculoskeletal disorders of the upper limbs. | 1 week |
