Introduction: Studies have shown the gluteus maximus and gluteus medius (gluteal complex) strengthening is an effective addition to treatment for patellofemoral pain syndrome (PFPS) (1-15). Research also demonstrates, adding core strengthening (rectus abdominis, external obliques and paraspinals) to gluteal complex strengthening may provide additional benefits (13, 15). This 2016 study by Saudi Arabian researchers demonstrates that core strengthening combined with conventional physical therapy (general hip and knee strengthening program) can reduce pain and improve balance in females with PFPS.

Effects of Performing an Abdominal Drawing-in Maneuver During Prone Hip Extension Exercises on Hip and Back Extensor Muscle Activity and Amount of Anterior Pelvic Tilt

Article

Introduction: The "abdominal drawing-in maneuver (ADIM)" is a light contraction of the transverse abominis (and muscles of the intrinsic stabilization subsystem) achieved by gently pulling the lower abdominal region away from one's waist band (1). Increased activity of these muscles has been shown to play an important role in stabilizing the lumbar spine, pelvis and sacroiliac joint (2-11). This 2007, South Korean study, examined local muscle activity and pelvic tilt angle when using the AD

Core Stability Measures as Risk Factors for Lower Extremity Injury in Athletes

Research Review: Core Stability Measures as Risk Factors for Lower Extremity Injury in Athletes

Introduction: Lower extremity injuries may impact between 30% and 50% of athletes during a competitive season, leading to missed time in practice, games, or an entire season (1-2). Many lower extremity injuries are associated with impaired core stability; especially, in female athletes (3-8). This 2004 prospective study by American researchers on collegiate athletes, shows that impaired core stability (lumbo pelvic hip complex), specifically hip external rotation weakness, may increase lower-extremity injury risk. Human movement professionals should assess and address the hip external rotator strength of athletes to reduce the risk of

Unilateral Hip Rotation Range of Motion Asymmetry in Patients With Sacroiliac Joint Regional Pain

Research Review: Unilateral Hip Rotation Range of Motion Asymmetry in Patients With Sacroiliac Joint Regional Pain

Introduction: Research has demonstrated a correlation between low back pain (LBP), hip external rotation greater than internal rotation, and asymmetries in hip range of motion (ROM) (1 - 3). Additionally, research has demonstrated asymmetrical external rotation ROM in individuals with sacrociliac joint (SIJ) dysfunction (4 - 6). Prior research has demonstrated a correlation between SIJ pain and a relative tilt of a pelvic innominate (7 - 8); however, these studies did not make an attempt to also correlate changes in hip ROM. This 1998 study by American researchers demonstrates that hip external rotation ROM is asymmetrical and significantly greater on the side of the posteriorly inommin

The Effect of Different Rest Intervals Between Sets on Volume Components and Strength Gains

Research Review: The Effect of Different Rest Intervals Between Sets on Volume Components and Strength Gains.

Why the Study is Relevant: Recommendations on inter-set rest interval length for improving muscular strength vary between strength training organizations (1 - 3). This 2008 study compared changes in strength among 15 resistance-trained participants when using 2- or 4- minute rest intervals. Strength adaptations were similar in both groups, despite greater volume performed in the 4-minute rest interval group. This suggests that human movement professionals may recommend 2-minute or 4-minute inter-set rest intervals for promoting optimal strength adaptations.
