Although some variables associated with running injuries require high-tech equipment such as instrumented treadmills and 3-dimensional (3D) motion capture systems many of the kinematic abnormalities recognized in runners with injuries can 483-15-8 IC50 be measured using a simple 2-dimensional (2D) video-based running analysis using readily available and fairly inexpensive tools. The objective of this article is to provide a framework for a systematic video-based running biomechanics analysis strategy based on the current evidence on running injuries. QS 11 Although some from the proposed variables of interest ill have an impact on running performance the primary focus of this analysis plan is to identify biomechanical factors related to common injuries in runners. Furthermore there are QS 11 many other factors that may be related and even causative intended for injuries while running including training errors current wellness status (ie recent injury) and/or structural abnormalities (ie leg length of time discrepancy pes planus feet deformity etc). 6 several However the concentrate of the this assessment is restricted to running kinematics particularly the in the sagittal and anterior plane which might be easily seen with normal 2D online video. A working biomechanics research should be an important component of the evaluation because of the wounded runner or perhaps for screening process for harm prevention to fit a physical examination and thorough history. ANALYSIS SETUP Treadmill Setup Although some studies possess identified small differences in treadmill running when compared with overground running these differences have mainly been associated QS 11 with muscle activation patterns and joint makes. 8 9 In general kinematic patterns during treadmill running are very just like those noticed during overground running. 10–12 As such performing a video-based analysis of joint kinematics while running on a treadmill should provide valuable insight into running kinematics during overground running and is more practical for performing this evaluation. Running velocity affects lower extremity kinematics. 13 Therefore matching treadmill velocity to a similar speed at which an injured runner experiences symptoms should QS 11 be accommodated if possible. When evaluating a symptom-free runner 1 strategy that can be used is to arranged the treadmill velocity to match the QS 11 running velocity of the runner when performing a “long run ” which is a common term used for the longest distance run in the recent past. The rationale for selecting this velocity is that in the event that runners are demonstrating abnormal biomechanics while performing longer runs these faults will certainly accumulate over the longer exercise period and 483-15-8 IC50 could contribute to running injuries. Cameras Many high-definition cameras are available at varying price points. Both image resolution and temporary resolution should be considered when selecting cameras to get video-based movement analysis. Many video cameras possess excellent image resolution QS 11 but are limited to 30 frames per second. Cameras 483-15-8 IC50 with higher frame rates (eg ≥120 Hz) can provide cleaner images that are easier to evaluate and more appropriate for the evaluation of running kinematics. More recently released smartphones and tablets can be adjusted to acquire online video at increased frame costs and provide ample video for this specific purpose. Views When conducting a video-based analysis we recommend that at a minimum a couple of orthogonal (at right facets to each other) views happen to be included. The analysis given in this article works on the lateral observe and a posterior observe. Others 483-15-8 IC50 can include an susodicho view or perhaps lateral displays from equally relative ends. Multiple displays from every single camera which include zoomed-in thoughts about the ft . and rearfoot as well as zoomed-out views of your entire body may help. Many of these tastes shall should be modified to work in the constraints of your clinical environment. Maintaining a.
