Researchers at Nazareth College School of Physical Therapy in Rochester, NY conducted two clinical studies. The first was to determine the immediate effects of using NuNee to relieve Anterior Knee Pain (AKP), including patellofemoral pain. The second was to determine the effect of using NuNee for 6 weeks. Their work provided clinical proof that nearly 9 of 10 people diagnosed with AKP experienced immediate relief and restored knee function. Study participants also reported no pain after 6 weeks of use. PDFs of the research abstracts and posters are provided below.
Participants were screened for Anterior Knee Pain by a primary investigator to rule out other causes of knee pain. Their height, weight and BMI were measured. Participants identified their current level of pain on a 0-10 numerical rating scale. Subjects completed a single functional test including stair ambulation, squat or running, depending on what was most provocative. They completed testing without the brace then with the brace, and a pain rating was recorded during each test scenario to identify immediate response.
When engaging in provocative activity, 89% reported decreased pain immediately after donning the brace. Results show a mean score of 3.38 on the numerical rating scale with provocative activity without the brace, and 1.62 with the brace, resulting in significant decreases in reported pain. 5 participants also reported improvements in their pain at rest when wearing the brace.
Participants were screened for Anterior Knee Pain after six weeks by a primary investigator using a standardized musculoskeletal exam. Participants self-reported initial pain using the numerical rating scale of 0-10 and completed the Kujala Anterior Knee Pain Questionnaire, a 13-item screening instrument designed to assess patellofemoral pain in adolescents and young adults. They then utilized the brace for six weeks while exercising and logged usage. At follow-up, ratings with and without the brace during the same functional activities were obtained along with the Kujala Score.
After six weeks, participants demonstrated statistically and clinically significant changes in Kujala and numerical rating scale scores. During functional testing at follow up, 100% of participants reported pain scores of 0/10 while using the brace, suggesting that the NuNee brace can reduce pain and improve function when worn during physical activity in individuals with anterior knee pain.
