NCT07003113

Brief Summary

We are examining the use of restricted blood flow, through full occlusion, on a single thigh for 50 minutes (5 minutes on, 5 minutes off), completed every other day for 2 weeks to improve function in individuals with knee osteoarthritis and low back pain.

Outcome Measures

Primary Outcomes (5)

  • Preferred walking speed

    Changes in preferred walking speed (m/s) from intervention

    At baseline (from enrollment) until end of intervention (3 weeks).

  • Muscle strength

    Change in quadriceps, hamstring, and hip strength

    From baseline (enrollment) until end of intervention (3 weeks)

  • Patient Reported Outcomes

    Change in subjective function and reporting based on questionnaires

    At baseline (enrollment) through the intervention (3 weeks)

  • Gait Kinematics

    Changes in gait kinematics (in degrees) from intervention

    At baseline (from enrollment) until end of intervention (3 weeks).

  • Gait Kinetics/Moments

    Changes in gait kinetics (joint moments) (in N/m) from intervention

    At baseline (from enrollment) until end of intervention (3 weeks).

Secondary Outcomes (1)

  • Cartilage Health

    From baseline (enrollment) until completion of intervention (3 weeks)

Study Arms (2)

IC Arm

EXPERIMENTAL
Device: Ischemic Preconditioning

Sham Arm

SHAM COMPARATOR
Device: Sham Intervention

Interventions

The intervention arm will include full blood flow occlusion in one thigh for 5 minutes followed by 5 minutes of reperfusion for a cycle of 50 minutes.

IC Arm

This intervention includes 25mmHg of pressure, which is not sufficient for blodo flow occlusion.
