Investigator's will perform a prospective, randomized, controlled study. All subjects in this group will be adults who have sustained a distal radius fractured treated with cast immobilization (non-operative) at San Antonio Military Medical Center (SAMMC) clinic system. Participants will be provided information about the study and inclusion/exclusion criteria, and upon conclusion of the formal consenting process, and signature of the consent document, will be considered enrolled in the study. Prior to intiation of any study procedures each patient must be cleared for participation in treatment by his or her surgeon as per standard post-fracture protocol. Medical clearance will be documented on the Enrollment form (Appendix A) and the Medical History form (Appendix K). This will be verified by accessing the medical record to confirm that a referral was made for post-fracture rehabilitation. Before initiation of treatment, the enrolled subjects will be randomized to either a standard rehabilitation group or an occlusion training rehabilitation group. Randomization with be performed with a random number generator. Treatment will be initiated approxmiately 6 weeks s/p fracture (when cleared by the orthopedic surgeon). Participantswill undergo approximetely 8-12 weeks of treatment with therapy sessions two to three days a week (consistent with standard of care), and will have re-assessments completed at approximately 4 weeks, 8 weeks, and 12 weeks after initiating the training protocol. The 12-week time point (after initiation of therapy) will be at approximately the same time that patients are released for full activity per standard of care.
The control (non-occlusion training) group will follow the standard s/p distal radius fracture rehabilitation protocol. Treatment will include passive, active assistive,active range of motion (P/AA/AROM) to wrist, forearm and hand; desensitization as needed; edema control as needed; heat/cold modalities as needed; and strengthening exercises. Specific strengthening exercises will include wrist flexion/extension over a foam wedge, forearm pronation/supination with arm positioned at side and elbow at 90 degrees, thumb opposition (pinch strength) as well as grip strengthening. The amount of resistance used with be determined by patient tolerance and post operative precautions.
The occlusion training group will follow the same protocol as described above but will utilize occlusion training with the strengthening exercises. We will use an established occlusion training protocol already being used at the CFI. The resistance for strength training will be determined based on the individual participants tolerance. A cuff will be wrapped around the most proximal portion of the arm of the involved extremity. In order to individualize the pressure for each subject, the limb occlusion pressure will be measured (with dopplar ultrasound over the radial artery at the wrist level) at the first scheduled therapy visit. Limb occlusion pressure is the pressure necessary to completely occlude arterial blood flow. The cuff pressure utilized during the post-operative exercises will be set at 50% of the limb occlusion pressure. Repetions will be 30, 15, 15 and 15 for each of the four sets. A 30-second rest will be given between sets. The tourniquet will stay inflated throughout the entire exercise and rest sessions, and no longer than 30 minutes consecutively for any time that the tourniquet is inflated. After completion of the 4 sets the tourniquet pressure will be deflated. The subjects' strength will be re-assessed approximately every 2-4 weeks and the load will be increased as tolerated.

No Intervention: non-oclusion training group
The control (non-occlusion training) group will follow the standard s/p distal radius fracture rehabilitation protocol. Treatment will include passive, active assistive,active range of motion (P/AA/AROM) to wrist, forearm and hand; desensitization as needed; edema control as needed; heat/cold modalities as needed; and strengthening exercises.
Active Comparator: occlusion traingn with tourniquet
The occlusion training group will follow the same protocol as described above but will utilize occlusion training with the strengthening exercises. Investigators will use an established occlusion training protocol already being used. Intervention: Occlusion training with tourniquet (DELFI PTS ii portable tourniquet system)
Device: DELFI PTS ii portable tourniquet
A cuff will be wrapped around the most proximal portion of the arm of the involved extremity. In order to individualize the pressure for each subject, the limb occlusion pressure will be measured (with doppler ultrasound over the radial artery at the wrist level) at the first scheduled therapy visit. The cuff pressure utilized during the post-operative exercises will be set at 50% of the limb occlusion pressure. The subjects' strength will be re-assessed approximately every 2-4 weeks and the load will be increased as tolerated.
- grip strength [ Time Frame: 18 weeks ]grip strength will be assessed using the JAMAR Hand Dynamometer
- pinch strength [ Time Frame: 18 weeks ]Pinch strength will be assessed using the PG-60 Pinch Gauge. The mean of three successive trials will be recorded for each pinch position (tip, key and palmar)
- joint range of motion [ Time Frame: 18 weeks ]Joint range of motion (ROM) will be assessed using a plastic goniometer
- Performance measure DASH [ Time Frame: 18 weeks ]a 30-item self-report measure that assesses a subject's perceived ability to complete twenty-one upper extremity functional activities using a 5-point Likert scale. The cumulative DASH score is scaled from 0 to 100, with higher scores indicating increased disability
- Performance measure PRWE [ Time Frame: 18 weeks ]a 15-item questionnaire that assesses wrist pain (5 items) and disability (10 items) in activities of daily living.
- Performance measure JTHFT [ Time Frame: 18 weeks ]is a seven part test that evaluates the time needed to perform seven hand-related tasks
- Performance measure PSFS [ Time Frame: 18 weeks ]a patient-specific outcome measure to assess functional status. The patient is asked to identify three to five activities that he or she has difficulty performing due to his or her condition. The patient then rates the amount of limitation he or she has in performing each of these activities on an 11-point scale with 0 being unable to perform the activity and 10 being able to perform the activity with no problem. An average score for the activities gives an ability score out of 10.
