Assessment of Dynamic Knee Valgus between Lateral Step-Down Test and Running in Female Runners with and without Patellofemoral Pain Using Two-Dimensional Video Analysis.

Clin Pract 2022 Jun 10;12(3):425-435. Epub 2022 Jun 10.

Postgraduate Program of Physical Education, Federal University of Sergipe (UFS), São Cristovão 49100-000, Brazil.

Dynamic knee valgus (DKV) is a frontal plane knee kinematic alteration that has been associated with patellofemoral pain (PFP) in female runners. DKV is commonly assessed in clinical practice by measuring frontal plane knee projection angle (FPPA) during squat tests. However, it remains unclear whether the DKV observed in these tests is similar to or correlates with that observed during running in female runners. Read More

Mobilization With Movement as Therapy to Reduce Knee Pain and Increase Knee Range of Motion.

J Sport Rehabil 2022 Jun 20:1-4. Epub 2022 Jun 20.

Concordia University, Chicago, IL,USA.

Clinical Scenario: Knee pain and limited knee range of motion (ROM) are among the most common conditions found in individuals who report lower body health-related issues. Factors such as weight gain, lack of mobility, balance issues, and pain can lead to a more sedentary lifestyle, which, in turn, causes knee stiffness or knee limited ROM. As a result, the patient will be at higher risk of osteoporosis, patellofemoral pain syndrome, reduced quadriceps strength, heart disease, and even depression. Read More

Magnetic resonance imaging appearance of breaststroker's knee.

Pediatr Radiol 2022 Jun 8. Epub 2022 Jun 8.

Department of Radiology, Rady Children's Hospital, 3020 Children's Way, San Diego, CA, 92123, USA.

Breaststroker's knee is an overuse syndrome resulting from similar repetitive movements in competitive swimmers that has been described in the orthopedic literature. The typical symptoms are medial knee pain with tenderness to palpation at the tibial collateral ligament or inferomedial patella. Despite these localizing symptoms on clinical exam, arthroscopic studies have failed to demonstrate a specific structural abnormality corresponding to this syndrome, although some have reported thickened medial synovial plica, medial-predominant synovitis or patellofemoral cartilage loss in association knee pain with breaststroke swimmers.

Reversing the Mismatch With Forefoot Striking to Reduce Running Injuries.

Front Sports Act Living 2022 19;4:794005. Epub 2022 May 19.

Faculty of Sport and Health Sciences, Technical University of Munich, Munich, Germany.

Recent studies have suggested that 95% of modern runners land with a rearfoot strike (RFS) pattern. However, we hypothesize that running with an RFS pattern is indicative of an evolutionary mismatch that can lead to musculoskeletal injury. This perspective is predicated on the notion that our ancestors evolved to run barefoot and primarily with a forefoot strike (FFS) pattern. Read More

Effectiveness of adjunctive treatment combined with exercise therapy for patellofemoral pain: a protocol for a systematic review with network meta-analysis of randomised controlled trials.

BMJ Open 2022 05 19;12(5):e054221. Epub 2022 May 19.

Department of Physical Therapy, Universidade Federal de São Carlos, São Carlos, Brazil.

Introduction: Patellofemoral pain (PFP) is a chronic condition that affects up to 25% of the general population and has a negative impact on functionality and quality of life due to the high levels of pain experienced by these patients. In order to improve pain and function, rehabilitation programmes that combine adjunctive treatments with exercise therapy are often used in research and clinical settings. However, despite the variety of adjunctive treatments available, their effectiveness when compared with exercise therapy has yet to be elucidated. Read More

The association and reliability of the frontal plane projection angle during the lateral step down test on knee function in patients with patellofemoral pain.

Knee 2022 Jun 10;36:87-96. Epub 2022 May 10.

School of Health & Rehabilitation Sciences, College of Medicine, The Ohio State University, Columbus, OH, United States; Sports Medicine Research Institute, The Ohio State University Wexner Medical Center, United States; Department of Orthopaedics, The Ohio State University Wexner Medical Center, United States.

Background: The lateral step-down test is used by physical therapists (PT) to identify movement faults in patients with patellofemoral pain (PFP).

Group-based exercice training programs for military members presenting musculoskeletal disorders - protocol for a pragmatic randomized controlled trial.

BMC Musculoskelet Disord 2022 Apr 18;23(1):366. Epub 2022 Apr 18.

Center for Interdisciplinary Research in Rehabilitation and Social Integration (Cirris), Québec, Canada.

Background: Musculoskeletal disorders are a leading cause of morbidity and the most prevalent source of disability among soldiers. Their high prevalence in armed forces and limited ressources have led to problems related to access to physical rehabilitation care. To increase access, supervised group-based exercise programs for the most prevalent musculoskeletal disorders (low back pain, patellofemoral pain, rotator cuff-related shoulder pain or lateral ankle sprain) have been developed at a Canadian Armed forces (CAF) base, but their effectiveness has not been evaluated.
