Use of a Vibration Tool for Postoperative Pain Control in Distal Radius Fractures

Traditionally, occupational therapists have utilized vibration for sensory re-education in compression neuropathies and peripheral nerve injuries. Vibration is also commonly used for desensitization of hypersensitivity following amputation, crush injury, and for hypersensitive scarring. Since the vibration tool is readily available in the hand therapy clinic, vibration analgesia should be further explored in the hand clinic to help reduce pain. Vibration is a simple, and non-invasive, tool and would be easy, economical, and practical to implement into the hand clinic for postoperative pain control. This research project will evaluate whether vibration can be a useful adjunct to current postoperative pain modalities. With a multidisciplinary approach, the investigators hope to highlight the use of non-opioid modalities of pain control in distal radius fractures and believe that the findings from this study may apply to other painful conditions of the hand as well.

• Vibration tool (Device), also known as Norco NC70209 Mini Massager: Therapeutic mini massager for scar management, desensitization, muscle stimulation, oral stimulation and sensory re-education. Seek pain relief for sore achy muscles, tendons or bones.

Primary outcomes

• QuickDASH (Disabilities of the Arm, Shoulder, and Hand) Questionnaire [up to 8 week post-surgery]: An 11-item, self-report questionnaire designed to measure physical function and symptoms in patients with any or several musculoskeletal disorders of the upper limb; scored from 0 (no disability) to 100 (most severe disability).
• PROMIS Bank v1.1 - Pain Interference Computer Adaptive Test [up to 8 weeks post-surgery]: A 4-6 item self-reported questionnaire designed to measure the consequences of pain on relevant aspects of a person's life; the T-score rescales the raw score into a standardized score with a mean of 50 and a standard deviation of 10; low scores represent less pain interference, while high scores represent greater interference.
• PROMIS Bank v2.0 - Upper Extremity Computer Adaptive Test [up to 8 weeks post-surgery]: A 4-6 item self-reported questionnaire designed to measure upper extremity function; the T-score rescales the raw score into a standardized score with a mean of 50 and a standard deviation of 10; low scores represent less function, while high scores represent greater function.
• Pain Visual Analog Scale (VAS) [up to 8 weeks post-surgery]: Scored from 0 (no pain) to 10 (worst possible pain)

Secondary outcomes

• Opioid Use [up to 8 weeks post-surgery]: Number of opioid pain medication tablets consumed
