Outcome Measures

Primary Outcomes (1)

  • Change in Patient Rated Tennis Elbow Evaluation (PRTEE)

    Change in score on 'Patient rated tennis elbow evaluation' total score from baseline to 12 month final follow up. Lower numbers suggest less pain, higher scores suggest more pain. Total score 0-100. Includes pain subscale (0-50) Specific activities subscale (0-60) Usual activities subscale (0-40) Function Subscale= (specific activities score + usual activities score)/2 (0-50) Total Score= Pain subscale + Function Subscale (0-100)

    12 months

Secondary Outcomes (4)

  • Numeric Pain Rating Scale

    12 months

  • Pain Free Grip Strength

    at final therapy visit up to 12 weeks after enrollment

  • Maximum Grip Strength

    at final therapy visit up to 12 weeks after enrollment

  • Other Treatments Received

    12 months

Study Arms (2)

Blood flow restriction with physical/occupational therapy

EXPERIMENTAL

physical/occupational therapy including use of blood flow restriction tourniquet over 6 visits (within a twelve week period).

Device: Blood flow restriction tourniquet

Evidence based physical/occupational therapy

ACTIVE COMPARATOR

evidence based physical/occupational therapy program over 6 visits (within a twelve week period) without use of blood flow restriction tourniquet

Other: Evidence based physical/occupational therapy

Interventions

A blood flow restriction tourniquet, which impedes arterial flow to extremity at 50% of usual flow.

Also known as: Delfi personalized tourniquet system
