Low-Intensity Pulsed Ultrasound for Chronic Patellar Tendinopathy: a Randomized, Double-Blind, Placebo-Controlled Trial Fall 2008
OBJECTIVE: Patellar tendinopathy (PT) is a common and significant clinical condition for which there are few established interventions. One intervention that is currently being used clinically to manage PT symptoms is the introduction of low-intensity pulsed ultrasound (LIPUS). The aim of this study was to investigate the clinical efficacy of LIPUS in the management of PT symptoms.
CONCLUSION: These findings suggest that LIPUS does not provide any additional benefit over and above placebo in the management of symptoms associated with PT.

Efficacy of a Target-Matching Foot-Stepping Exercise on Proprioception and Function in Patients with Knee Osteoarthritis. Fall 2008
OBJECTIVE: To investigate the efficacy of high, repetitive, target-matching foot-stepping exercise (TMFSE) performed in a sitting position on proprioception, functional score, and walking velocity for patients with knee osteoarthritis (OA).
CONCLUSION: TMFSE in sitting appears to be an option for exercise in patients with mild to moderate knee OA. This may be an especially attractive option for patients who may have pain with weight-bearing exercises. A longitudinal study with a larger sample size is needed to confirm the potential use of TMFSE for patients with knee OA.

Hip Strength and Hip and Knee Kinematics During Stair Descent in Females With and Without Patellofemoral Pain Syndrome Summer 2008
PURPOSE: To determine if females presenting with patellofemoral pain syndrome (PFPS) from no discernable cause other than overuse demonstrate hip weakness and increased hip internal rotation, hip adduction, and knee valgus during stair descent.
CONCLUSION: Subjects with PFPS had significant hip weakness but did not demonstrate altered hip and knee kinematics as previously theorized. Additional investigations are needed to better understand the association between hip weakness and PFPS etiology.

Joint Loading in the Lower Extremities During Elliptical Exercise Spring 2008
Purpose: To determine the joint loading during elliptical exercise (EE) by a detailed three-dimensional dynamic analysis, and to compare the results with those during level walking.
Conclusion: Different lower-limb kinematics and kinetics were found between EE and level walking. Smaller vertical PRF and loading rates during EE were achieved at the expense of greater hip flexor and knee extensor moments. Use of the elliptical trainer for athletic and rehabilitative training would have to consider users' joint function and muscle strength, especially at the knee, to avoid injuries.

Development of a Clinical Prediction Rule to Identify Patients With Knee Pain and Clinical Evidence of Knee Osteoarthritis Who Demonstrate a Favorable Short-Term Response to Hip Mobilization Fall 2007
Purpose: The primary purpose of this study was to develop a clinical prediction rule (CPR) for identifying patients with knee pain and clinical evidence of knee osteoarthritis (OA) with favorable short-term response to hip mobilizations. The secondary purpose was to determine the predictive validity of individual clinical tests for identifying these same patients.

15-Year Follow-up of Neuromuscular Function in Patients With Unilateral Nonreconstructed Anterior Cruciate Ligament Injury Initially Treated with Rehabilitation and Activity Modification: A Longitudinal Prospective Study Fall 2007
Background: It has been suggested that neuromuscular function is of importance in the overall outcome after anterior cruciate ligament (ACL) injury. Hypothesis: Good neuromuscular function can be achieved and maintained over time in subjects with ACL injury treated with rehabilitation and activity modification but without reconstructive surgery.

Effect of static stretching of muscles surrounding the knee on knee joint position sense. Summer 2007
Muscle stretching is widely used in sport training and rehabilitation. Considering the important contribution of joint position sense (JPS) for knee joint stability and function, it is legitimate to question if stretching could alter the knee JPS. OBJECTIVE: To evaluate if a stretch regimen consisting of three 30-second stretches would alter the knee JPS.

Analysis of hip strength in females seeking physical therapy treatment for unilateral patellofemoral pain syndrome. Summer 2007
Decreased hip strength may be associated with poor control of lower extremity motion during weight-bearing activities, leading to abnormal patellofemoral motions and pain. OBJECTIVES: To investigate whether females seeking physical therapy treatment for unilateral patellofemoral pain syndrome (PFPS) exhibit deficiencies in hip strength compared to a control group.

Lengthening the Hamstring Muscles Without Stretching Using "Awareness Through Movement". Winter 2006
Purpose. Passive stretching is widely used to increase muscle flexibility, but it has been shown that this process does not produce long-term changes in the viscoelastic properties of muscle as originally thought. The authors tested a method of lengthening hamstring muscles called "Awareness Through Movement" (ATM) that does not use passive stretching.

Neuromuscular Activation in Conventional Therapeutic Exercises and Heavy Rresistance Exercises: Implications for Rehabilitation. Fall 2006
This study examined the level of knee joint neuromuscular activation during four conventional therapeutic exercises (quadriceps femoris muscle setting, manual lateralization of the patella, rhythmic stabilization, and the pelvic bridging exercise) and four heavy resistance exercises (free-weight squat with a barbell, horizontal seated leg press, isolated knee extension with a cam mechanism, and isolated hamstring muscle curl) in young, untrained men who were healthy.

Rehabilitation After Cell Transplantation for Cartilage Defects. Fall 2006
Rehabilitation is a key element of successful treatment of cartilage defects with cell transplantation. The process of graft maturation takes approximately 18 months and cannot be accelerated, but requires carefully introduced steps leading to early recovery of joint function.
