About this trial

This study will look at the effect of using a blood flow restriction device during low load strengthening exercises on patients with tibial shaft fractures, compared to patients performing exercise without the device. The study will compare muscle strength, muscle size, fracture healing, and return to normal function between the two groups.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Adult with closed tibial shaft fracture

Ability to begin physical therapy treatment within 2 weeks post-operatively

Disqualifiers

History of osteoporosis or osteopenia

Impaired circulation in the limb

Active deep vein thrombosis

Clotting disorders or other elevated risk of embolism

Trial design

Design model

Parallel

Treatments tested in this trial

  • Blood Flow Restriction with low load exercise

    Device

    Cuff/tourniquet will be applied to proximal leg at hip crease and inflated to 60-80% of limb occlusion pressure to decrease venous blood flow in the limb while performing exercise.

  • Therapeutic Exercise

    Other intervention

    Exercise performed at appropriate load as guided by physical therapist

Treatment groups

40 Participants
are divided into 2 treatment groups
Group A: Blood flow restriction trainingExperimental treatment 1 intervention
Group B: Traditional physical therapyActive comparator 1 intervention
