The knee valgus angle can be corrected surgically or with a more conservative non-operative approach. Increasing running cadence may be an effective biomechanical gait retraining intervention to reduce knee valgus and thus patellofemoral pain. The primary purpose of this study was to examine if an increase in cadence could change the knee valgus angle. Methods: Ten asymptomatic recreational runners were recorded running on a treadmill during control and experimental intervals. Each interval lasted five minutes, and participants ran at 100% and 110% of their baseline cadence. Peak angles of knee valgus were compared between both intervals using the video analysis software application Dartfish Express. A paired sample, a two-tailed t-test, was used to determine the significant difference between bilateral frontal plane knee angle measurements during both intervals. Results: The average decrease in knee valgus measured in control versus experimental intervals was 2.23\u00b0 for the right leg and 2.05\u00b0 for the left leg, with a significance of p &lt; 0.001 and p &lt; 0.001, respectively. Conclusion: The results indicated a statistically significant decrease in angles of dynamic knee valgus, attributable to increased cadence. These changes in knee valgus angle are likely to have a positive impact on preventing and reducing pain associated with PFP.<\/jats:p>","DOI":"10.3390\/clinpract14060195","type":"journal-article","created":{"date-parts":[[2024,11,14]],"date-time":"2024-11-14T09:14:31Z","timestamp":1731575671000},"page":"2491-2498","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Running Cadence and the Influence on Frontal Plane Knee Deviations"],"prefix":"10.3390","volume":"14","author":[{"given":"Jacob R.","family":"Peterson","sequence":"first","affiliation":[{"name":"Physical Therapy Department, William Carey University, Hattiesburg, MS 39401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Collin R.","family":"Sanders","sequence":"additional","affiliation":[{"name":"Physical Therapy Department, William Carey University, Hattiesburg, MS 39401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathan S.","family":"Reynolds","sequence":"additional","affiliation":[{"name":"Physical Therapy Department, William Carey University, Hattiesburg, MS 39401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Conner A.","family":"Alford","sequence":"additional","affiliation":[{"name":"Physical Therapy Department, William Carey University, Hattiesburg, MS 39401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J.","family":"Platt","sequence":"additional","affiliation":[{"name":"Physical Therapy Department, William Carey University, Hattiesburg, MS 39401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey J.","family":"Parr","sequence":"additional","affiliation":[{"name":"School of Health Professions, University of Southern Mississippi, Hattiesburg, MS 39406, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Twum","sequence":"additional","affiliation":[{"name":"School of Health Professions, University of Southern Mississippi, Hattiesburg, MS 39406, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-4803-4682","authenticated-orcid":false,"given":"James R.","family":"Burns","sequence":"additional","affiliation":[{"name":"Physical Therapy Department, William Carey University, Hattiesburg, MS 39401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David R.","family":"Dolbow","sequence":"additional","affiliation":[{"name":"Physical Therapy Department, William Carey University, Hattiesburg, MS 39401, USA"},{"name":"College of Osteopathic Medicine, William Carey University, Hattiesburg, MS 39401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,14]]},"reference":[{"key":"ref_1","first-page":"88","article-title":"Patellofemoral Pain Syndrome","volume":"99","author":"Gaitonde","year":"2019","journal-title":"Am.
