“…We chose to report force, rather than torque, to facilitate the comparison of our results to previously established normative values that were also reported in units of force (or percent body weight). 1,3,5,19 Future studies using hand-held dynamometry should weigh the merits of reporting force versus torque. However, when reporting units of force, we acknowledge that some assurance of equality of height between groups should be included.…”

“…The test positions were selected based on their similarity to traditional manual muscle testing procedures 20 and have been reported to be highly reliable for testing isometric strength with hand-held dynamometers. 6,19 Hip abduction isometric strength testing was performed with subjects positioned in sidelying on a treatment table (Figure 1). A pillow was placed between the subjects' legs, using additional toweling as needed, such that the hip of the leg to be tested was abducted approximately 10°as measured with respect to a line connecting the anterior superior iliac spines.…”

Study Design: Cross-sectional. Objectives: To determine if females with anterior knee pain are more likely to demonstrate hip abduction or external rotation weakness than a similar, asymptomatic, age-matched control group. Background: Diminished hip strength has been implicated as being contributory to lower-extremity malalignment and patellofemoral pain. The identification of reliable and consistent patterns of weakness in this population may assist health care professionals establish a more effective treatment plan. Methods and Measures: Hip abduction and external rotation isometric strength measurements were recorded for the injured side of 15 female subjects with patellofemoral joint pain (mean ± SD age, 15.7 ± 2.7 years; age range, 12-21 years). These were compared with strength measurements from the corresponding hip of 15 age-matched female control subjects (mean ± SD age, 15.7 ± 2.7 years; age range, 12-21 years). All strength measurements were made using hand-held dynamometers. Results: Subjects with patellofemoral pain demonstrated 26% less hip abduction strength (PϽ.001) and 36% less hip external rotation strength (PϽ.001) than similar age-matched controls. Conclusions:The results indicate that young women with patellofemoral pain are more likely to demonstrate weakness in hip abduction as well as external rotation than age-matched women who are not symptomatic. J Orthop Sports Phys Ther. 2003;33:671-676. Key Words: anterior knee pain, hip abduction, hip external rotation, knee, patella P atellofemoral joint pain (PFP) remains one of the most common orthopaedic complaints among adolescents and young adults, with reported incidence rates among athletes greater than 25%. 2,26,31,38 It has also been reported that females, as compared with their male counterparts, are significantly more likely to experience PFP. 9,35 Typically, patients complain of generalized retropatellar symptoms that present insidiously and tend to be exacerbated by prolonged sitting or repetitive weight-bearing activities over a flexed knee. Unfortunately for these individuals, this pain often becomes a chronic condition that may fail to respond to conservative measures. Willson, Joyner Sportsmedicine Institute, 601 Perimeter Dr., Suite 110, Lexington, Current literature suggests that, in the absence of direct trauma, the etiology of PFP is multifactorial. Factors related directly to the patellofemoral joint, including vastus medialis obliquus insufficiency, decreased hamstring, quadriceps, or iliotibial band flexibility, patella alta, and femoral anteversion, have received the most attention.

“…Thus, the entire lower extremity kinetic chain should be assessed. Since knee pain and effusion may have an inhibitory effect on lower extremity muscle function (10,18), the application of appropriate anti-inflammatory measures (ie., ice, elevation, compression bandaging) is recommended. After steps have been taken to control knee pain and effusion, appropriate rehabilitation exercises should be prescribed to facilitate lower extremity motor control.…”
