Study Details

Brief summary:

Occlusion training, resistance exercise performed with a specialized venous tourniquet, leads to beneficial changes in muscle strength at low resistance and minimal stress on the nearby joint. This novel resistance training has the potential to greatly improve muscle strength gains in individuals who are unable, for medical reasons, to perform the high resistance exercises typically required to improve strength. Our study will examine the effect of this technique on strength recovery following distal radius fracture repair. The primary objective of the intervention is to achieve accelerated recovery of forearm, wrist and hand function as assessed using measures such as grip/pinch strength, validated questionnaires, and functional outcome testing. Occlusion training can potentially serve as a specialty intervention for rehabilitation patients, reduce the cost of care, and improve the treatment options for both patients and providers.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18 - 65

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Status post open reduction internal fixation for a distal radius fracture
  • Males and females 18-65 years of age
  • Eligible to receive care at Military Treatment Facilities (DEERS eligible)
  • Must be able to read and write in English in order to consent

Exclusion Criteria:

  • Contralateral upper extremity involvement resulting in less than normal range of motion, muscle strength, or daily pain greater than 1/10.
  • Pregnancy - per patient self-report. Due the expected small number of pregnant individuals and resulting inability to account for its effect on resulting outcomes, these patients will not be included in the study.
  • Recent history of deep vein thrombosis, within the 12 months or on active treatment with anticoagulants
  • History of upper quadrant lymph node dissection
  • History of endothelial dysfunction
  • Patient endorsement of easy bruising
  • Active Infection
  • Cancer (current diagnosis per medical record)

Interventions and Outcome Measures

Arms

no intervention: non-occlusion training group

The control (non-occlusion training) group will follow the standard post-operative 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.

experimental: occlusion training with DELFI PTS ii 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. Intervention: occlusion training with tourniquet (DELFI PTS ii portable tourniquet system)

Interventions

occlusion training with tourniquet (DELFI PTS ii portable tourniquet system)

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. 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.

Primary outcome measure

  • Grip strength [ Time Frame: 18 weeks ]
