Background: Providing clinicians with an accurate method to predict kinetic measurements using 2D kinematic motion analysis is crucial to the management of distance runners. Evidence is needed to compare the accuracy of 2D and 3D kinematic measurements as well as measured and estimated kinetic variables.

Purposes: The objectives of this study were to (1) compare 2D video analysis of running kinematics with gold standard 3D motion capture and, (2) to evaluate published equations which estimate running kinetics using 2D kinematic and spatiotemporal values and modify these equations based on study findings.

Background: While previous research has assessed running kinematics for age-related differences that could increase the risk of a running-related injury, none of these studies have included high school aged runners or assessed running kinematics using 2-dimensional video analysis.

Purpose: The purpose of this study was to compare sagittal plane kinematics during treadmill running in high school cross-country and young adult recreational runners using 2-dimensional motion analysis techniques.

Methods: Twenty-five high school cross-country runners (13 women, 12 men) and 25 young adult recreational runners (12 women, 13 men) consented to participate in this study.

Background: Variations in vertical loading rates have been associated with overuse injuries of the lower extremity; however, they are typically collected using 3-dimensional motion capture systems and in-ground force plates not available to most clinicians because of cost and space constraints.

Purpose: The purpose of this study was to determine if kinetic measures commonly used to describe lower extremity loading characteristics could be estimated from step rate and specific sagittal plane kinematic variables captured using 2-dimensional motion analysis during treadmill running.

Study Design: Observational Study.

Background And Purpose: Every ten years the American Board of Physical Therapy Specialties conducts a practice analysis to revalidate and revise the description of specialty practice for sports physical therapy (SPT). The primary purpose of this paper is to describe the process and results of the most recent analysis, which defines the competencies that distinguish the subspecialty practice of (SPT). Additionally, the study allowed for the comparison of responses of board certified specialists in SPT to respondents who were not specialists while reflecting on demographic changes and evolving trends since the previous analysis of this physical therapy specialty practice was conducted 10 years ago.

Purpose/background: Exercise-related leg pain (ERLP) is a common problem in runners. The purposes of this study were to 1) report ERLP occurrence among adult community runners; 2) determine ERLP impact on daily activities; and 3) determine if there is a relationship between ERLP occurrence and selected potential risk factors including sex, age, years of running, ERLP history, body mass index (BMI), orthotic use, menstrual function, and training variables.

Methods: Community runners registered for a local race were invited to complete a questionnaire including demographics and potential risk factors.

Purpose: The purpose of this study was to examine the relationships between isotonic ankle plantar flexor endurance (PFE), foot pronation as measured by navicular drop, and exercise-related leg pain (ERLP).

Background: Exercise-related leg pain is a common occurrence in competitive and recreational runners. The identification of factors contributing to the development of ERLP may help guide methods for the prevention and management of overuse injuries.

Exercise related leg pain (ERLP) is a regional pain syndrome described as pain between the knee and ankle which occurs with exercise. Indiscriminant use of terminology such as "shin splints" has resulted in ongoing confusion regarding the pathoanatomic entities associated with this pain syndrome. Each of the pathoanatomic entities - medial tibial stress syndrome, chronic exertional compartment syndrome, tibial and fibular stress fractures, tendinopathy, nerve entrapment, and vascular pathology - which manifest as ERLP are each described in terms of relevant anatomy, epidemiology, clinical presentation, associated pathomechanics, and intervention strategies.
