Purpose: Tibial stress fractures (TSF) are among the most serious running injuries, typically requiring 6-8 wk for recovery. This cross-sectional study was conducted to determine whether differences in structure and mechanics exist between trained distance runners with a history of prior TSF those who have never sustained fracture. Methods: Female rearfoot strike pattern, aged 18 45 yr at least 32 km·wk−1, were recruited this study. Participants 20 subjects age- mileage-matched control no...

Study Design Single-subject with repeated measures. Objectives To determine if runners can use real-time visual feedback from an accelerometer to achieve immediate reductions in tibial acceleration and vertical-force loading rates. Background Stress fractures are a common injury among runners. Previous studies suggest that higher than normal rates at increased risk for stress fractures. If these be trained reduce the on their lower extremities, it may of Methods Five subjects participated...

Damage to the collateral ligaments of ankle is relatively common, particularly lateral ligaments; therefore, it important be aware detailed anatomy and frequency variation individual ligaments. Only two reports dimensions were found in literature, neither which considers all components ligament complex. Osteoligamentous preparations 40 ankles from 20 cadavers European Caucasian origin studied, mean values for length width determined, together with their occurrence. For as a whole,...

This study aimed to investigate anatomical variations within the medial collateral ligament complex of human ankle joint. Osteoligamentous preparations 40 ankles from 20 cadavers were studied. Six different component bands observed: four superficial (tibiospring, tibionavicular, posterior tibiotalar, and tibiocalcaneal ligaments), which only tibiospring tibionavicular ligaments constant, two deep (deep tibiotalar anterior was constant. No pattern observed in distribution additional bands. A...

Study Design Cross-sectional controlled laboratory study. Objectives To investigate the kinematics of hip, knee, and rearfoot in frontal transverse planes female distance runners with a history tibial stress fracture. Background Tibial fractures are common overuse injury runners, accounting for up to half all fractures. Abnormal lower extremity may contribute abnormal musculoskeletal load distributions, leading an increased risk Methods Thirty fracture were compared 30 age-matched...

Increased vertical impact loading during running has been associated with a variety of related injuries including stress fractures, patellofemoral pain, and plantar fasciitis.The purpose this study was to examine the acute long-term effect gait retraining program aimed at teaching runners high run softer.Nineteen tibial shock (TS) first underwent control period eight sessions treadmill over 2 wk, progressing from 15 30 min. This followed by wk using identical protocol. Real-time feedback TS...

Tibial acceleration is frequently measured in runners, and recent advances wireless technology have led to field studies measuring tibial outside the laboratory. However, it unknown whether laboratory measures of differ within runners. In addition, relationship between peak axial more measure resultant has not been determined.This study aimed determine are comparable, interchangeable.Nineteen healthy rearfoot striking runners 18 45 yr age participated. A precision accelerometer was aligned...

0422 Stress fractures are among the most serious injuries a runner can sustain. The majority of these occur in tibia, and females twice as likely to sustain this injury compared males. thought be related, part, abnormal loading during running. While retrospective studies informative, prospective essential establish cause effect. PURPOSE: purpose study was examine, prospectively, relationship between measures increased incidence tibial stress (TSF) competitive women runners. It hypothesized...

Proximal factors such as excessive frontal plane pelvis and trunk motion have been postulated to be biomechanical risk associated with iliotibial band syndrome. In addition, lateral core endurance deficiencies may related increased during running. The purpose of this cross-sectional investigation was determine if differences in biomechanics running, well exist between female runners previous syndrome controls. Gait were assessed 34 (17 syndrome). Multivariate analysis variance performed...

Study Design Controlled laboratory study, within-session design. Background Gait retraining has been proposed as an effective intervention to reduce impact loading in runners at risk of stress fractures. Interventions that can be easily implemented the clinic are needed. Objective To assess immediate effects sound-intensity feedback related during running on vertical peak, peak instantaneous rate, and average rate. Methods Fourteen healthy, college-aged who ran least 9.7 km/wk participated...
