Background Patellofemoral pain syndrome (PFPS) is the most common overuse injury in runners. Recent research suggests that hip mechanics play a role development of this syndrome. Currently, there are no treatments directly address atypical associated with injury. Objective The purpose study was to determine whether gait retraining using real-time feedback improves and reduces subjects PFPS. Methods Ten runners PFPS participated study. Real-time kinematic adduction (HADD) during stance...

Patellofemoral pain (PFP) is often seen in physically active individuals and may account for 25–40% of all knee problems a sports injury clinic.1 ,2 Patellofemoral-related occur more frequently women than men.3 PFP characterised by diffuse over the anterior aspect aggravated activities that increase patellofemoral joint (PFJ) compressive forces, such as squatting, ascending descending stairs prolonged sitting, well repetitive running. It, therefore, has debilitating effect on sufferers’...

Patellofemoral pain (PFP) is the leading cause of knee in runners. Proximal and distal running mechanics have been linked to development PFP. However, lack prospective studies limits establishing a causal relationship these The purpose this study was prospectively compare group female runners who went on develop PFP compared with healthy controls. It hypothesized that go would exhibit greater hip adduction, internal rotation, rear foot eversion.Four hundred underwent an instrumented gait...

Cross-sectional experimental laboratory study.To examine differences in running mechanics between runners who had previously sustained iliotibial band syndrome (ITBS) and with no knee-related injuries.ITBS is the second leading cause of knee pain most common lateral pain. Despite its prevalence, few biomechanical studies have been conducted to better understand aetiology. Because has both femoral tibial attachments, it possible that atypical hip foot could result development ITBS.The 35...

In the present study, we sought to determine effect of a traditional, 12 week aerobic training protocol on skeletal muscle fibre type distribution and satellite cell content in sedentary subjects. Muscle biopsies were obtained from vastus lateralis [n = 23 subjects (six male 17 female); body mass index 30.7 ± 1.2 kg m(-2)] before after weeks performed cycle ergometer. Immunohistochemical analyses used quantify myosin heavy chain (MyHC) isoform expression, cross-sectional area myonuclear...

The Y Balance Test was developed as a test of dynamic postural control and has been shown to be predictive lower-extremity injury. However, the relationship between hip strength performance on not fully elucidated.The goal this study identify components isometric Test, provide clinicians better guidance specific areas muscle address in event poor Test.Laboratory study.Biomechanics laboratory.A total 73 healthy participants (40 males 33 females) volunteered for study.None.Participants...

Study Design Cross-sectional laboratory study. Objectives To assess differences in hip strength, iliotibial band length, and knee mechanics during running between male runners with syndrome (ITBS) healthy controls. Background Flexibility, are commonly assessed patients ITBS. However, these variables have not been evaluated concurrently this population. Methods Thirty-four men participated (17 healthy, 17 ITBS). Hip strength was measured a handheld dynamometer, length using an inclinometer...

Background: Rate of torque development (RTD) measures the ability a muscle to produce quickly. Decreased quadriceps RTD may impair performance sporting tasks after surgery. Currently, little is known about variations in between anterior cruciate ligament (ACL)–reconstructed and noninjured limbs. Purpose: To determine differences quadriceps, rate timing knee extensor moment (KEM) development, flexion excursion during running ACL reconstruction with patellar tendon autograft. Study Design:...

Anterior cruciate ligament (ACL) injuries are associated with significant loss of strength in knee extensor muscles that persists despite physical therapy. The underlying mechanisms responsible for this protracted muscle weakness poorly understood; however, we recently showed myofiber atrophy and altered phenotype following ACL injury. We sought to further explore perturbations skeletal morphology progenitor cell activity an Muscle biopsies were obtained from the injured non-injured vastus...

Fibromyalgia is a common chronic pain condition that has significant impact on quality of life and often leads to disability. To date, there have been few well-controlled trials assessing the utility nonpharmacological treatment modalities such as transcutaneous electrical nerve stimulation (TENS) in management improvement function individuals with fibromyalgia.The purpose this study will be complete long-term, multicenter assess effects TENS women fibromyalgia.This phase II randomized,...

Despite significant rehabilitation, many athletes experience protracted weakness and faulty mechanics after anterior cruciate ligament reconstruction (ACLR). Clinical tests performed early in which predict knee at return-to-sport, are virtually unknown critically needed to guide clinical decision making. The purpose of this study is determine if quadriceps strength, Y balance (YB-A) reach distance, single-leg step-down test performance (SLSD) conducted 3 months post-ACLR predictive flexion...

The anterior cruciate ligament is the most commonly disrupted in knee high-performance athletes. Most recently, advancements surgical technique and graft fixation have enabled athletes to participate early postoperative rehabilitation, focusing on range of motion progressing patellar mobilization, strengthening, neuromuscular control. Several rehabilitation protocols exist with variations specific exercises, progression through phases, key components. ultimate goal return athlete preinjury...

Despite the intense focus on outcomes following an anterior cruciate ligament (ACL) reconstruction, it is not yet known whether unresolved abnormal hip and trunk neuromuscular control exists. The purpose of this study was to compare kinematics during running, abductor external rotator strength, between females who had undergone ACL reconstruction healthy participants. We compared 20 reconstructed individuals, measuring abduction rotation a test, performed instrumented gait evaluation...

Background: Anterior cruciate ligament (ACL) tears result in significant quadriceps muscle atrophy that is resistant to recovery despite extensive rehabilitation. Recent work suggests an elevated fibrotic burden the after injury, which may limit recovery. Elucidating mechanisms and cell types involved progression of fibrosis critical for developing new treatment strategies. Purpose: To identify factors contributing found injury. Study Design: Descriptive laboratory study. Methods: After ACL...

Abstract Background Despite best practice, quadriceps strength deficits often persist for years after anterior cruciate ligament reconstruction. Blood flow restriction training (BFRT) is a possible new intervention that applies pressurized cuff to the proximal thigh partially occludes blood as patient exercises, which enables patients train at reduced loads. This believed result in same benefits if were under high Objective The objective evaluate effect of BFRT on and knee biomechanics...

Synopsis Restoring quadriceps muscle strength is integral to recovery following an anterior cruciate ligament reconstruction. We argue that clinicians should re-evaluate their beliefs about open-chain exercises and measure this important variable improve outcomes for patients.
