Study summary

Biofreeze® is a topical analgesic, frequently used in the office or given to a patient for home use as a way to mitigate pain during the course of treatment. Rehabilitative exercises are considered an important component of care for shoulder pain patients, although pain can be a limiting factor in the advancement of rehabilitation. The purpose of this study is to evaluate the addition of Biofreeze® to an in-office group of shoulder pain patients to determine its impact on pain reduction. Methods: Patients 18-64 years old with mechanical shoulder pain who are candidates for standard shoulder therapy will be randomized into two groups (N=20). The Control group (N=10) will receive standard shoulder therapy alone while the Intervention group (N=10) will receive standard shoulder therapy plus Biofreeze® just prior to initiating the in-office exercise program. Values of pain (NPRS) and disability (ASES) will be recorded at baseline, 2 weeks, and 4 weeks. Hypotheses will be addressed by repeated measures ANOVAs within and between group, time, and interaction main effects. Clinical Relevance: Progression of therapeutic exercises can be limited by pain and the associated disability. The ability to decrease shoulder pain and disability with a topical analgesic will allow health care professionals to advance patients through a therapeutic exercise program without the restriction of pain. In turn, patients will correct the underlying condition of their shoulder pain at a faster rate.

  • Active comparator
    Biofreeze

    Apply 5 minutes before therapy by applying a small coin sized amount to the painful area. Subjects will then complete a standard shoulder therapy program.

    Drug: Biofreeze

  • No intervention
    Control

    Subjects in this arm will complete a standard shoulder therapy program as normal, with no intervention.

What researchers measure

Primary outcomes

  1. Change From Baseline of American Shoulder and Elbow Surgeons (ASES) Questionnaire at 2 Weeks

    The American Shoulder and Elbow Surgeons (ASES) Questionnaire is a self-report questionnaire measuring pain and disability. It is measured from 0 to 100, 0 being completely disabled and 100 being pain free and normal function. The total score is calculated using the following equation: (10-NPRS) x 5 = \_\_ + (5/3) x Cumulative ADL Score

    Time frame: 2 weeks

  2. Change From Baseline of Numeric Pain Rating Scale (NPRS) at 2 Weeks

    The Numeric Pain Rating Scale (NPRS) is a self-report scale measuring pain. It is measured from 0 to 10, 0 being pain free and 10 being the worse imaginable pain.

    Time frame: 2 weeks

  3. Change From Baseline of American Shoulder and Elbow Surgeons (ASES) Questionnaire at 4 Weeks

    The American Shoulder and Elbow Surgeons (ASES) Questionnaire is a self-report questionnaire measuring pain and disability. It is measured from 0 to 100, 0 being completely disabled and 100 being pain free and normal function. The total score is calculated using the following equation: (10-NPRS) x 5 = \_\_ + (5/3) x Cumulative ADL Score

    Time frame: 4 weeks

  4. Change From Baseline of Numeric Pain Rating Scale (NPRS)at 4 Weeks

    The Numeric Pain Rating Scale (NPRS) is a self-report scale measuring pain. It is measured from 0 to 10, 0 being pain free and 10 being the worse imaginable pain.

    Time frame: 4 weeks
