Conditions: Shoulder Pain
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 34
Healthy volunteers: no

Brief 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.

Detailed description:

Arms:
arm 1: 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. arm 2: Subjects in this arm will complete a standard shoulder therapy program as normal, with no intervention.

Interventions: intervention 1: Biofreeze
Intervention descriptions: intervention 1: None
