Introduction Software will compare gait parameters to speed/age/gender matched normative database Program will auto-detect foot strike type and compare to an appropriate database Gait Parameters Normative Database Treadmill speed is automatically calculated. 3.5 mph or less classified as walking 4.5 or greater classified as running Normative data collected at: Walking = 2, 3 mph Running = 5, 6, 7, 8, 9 mph Best to collect at one of these speeds if possible for best comparison to normal data Age groupings (walking and running rearfoot strike): 15-30 (also used for under 15) 31-45 46-60 60-75 (also used for 75+) Running forefoot strike database combined across all ages 3
Introduction Report Interpretation Parameters are represented visually with green/yellow/red regions Green zone Within plus/minus standard deviation of population mean Yellow zone Between one and two standard deviations of population mean Red zone Greater than two standard deviations away from population mean. Polarity of movement impairment is parameter specific - + 4
Introduction Example Parameter Interpretations Substantially shorter stance time Normal step length Narrower step width for right steps More toed in Normal contact ankle dorsiflexion Less contact knee flexion Substantially less contact hip flexion 5
Introduction Measurement Variability Background Biological variability Stride-to-stride variability is accounted for by averaging across strides in 10-second collection Measurement error The protocol was designed in order to provide as reliable data as possible while keeping it as simple and fast as possible. There will be some variation both within a clinician across days and across clinicians Between clinicians is typically less reliable then within a clinician Recommend re-testing patients by the same clinician to minimize this error source 6
RUNNING REPORTS
Running Reports Running Report Types Running parameters chosen based on movement impairments most commonly linked to specific running injuries Report types grouped by injuries General (all parameters) Patellofemoral Pain Patellar Tendon Pain Iliotibial Band Syndrome Greater Trochanteric Syndrome Low Back Pain Achilles Tendinopathy Shin Pain Plantar Heel Pain Bone Stress Injury 8
Running Reports Temporal- Spatial Paramerters All Running reports include: Cadence (steps per minute) Flight Time (seconds) Flight time included as an indication of step length, which cannot be measured directly during treadmill running. 9
