Smart 3D Running Gait Analysis
Running Economy(RE) Analysis
- Running Energy Efficiency
No markers or tedious setup procedures, just running.
Analysis of treadmill walking or running gait using depth sensing cameras.
It merges the capabilities of a biomechanics reserach lab with the simplicity of video analysis.
3D Running Gait
A complete 3D running analysis and biomechanical profile in less than a minute without markers.
When these forces act in the optimal way, they generate an efficient running stride with balanced distribution of loads on the joints.
Truly meaningful running gait assessment needs to involve the whole body and the forces acting on it.
3D Running Gait system covers all essential aspects of running mechanics and features:
- running economy based on mechanical work with elastic energy exchange
- temporal and spatial stride parameters, and force
- gait kinematics and joint loading for injury assessment
- elite and normative data from over 600 runners
- before-after overlay comparison
- data chart generation for over 60 parameters as function of speed
- comprehensive PDF report and video file for results sharing
All parameters are presented in relation to elite level performance or normative data from a group of over 600 runners to facilitate your assessment.
Report is divided into three main categories, Running Performance, Gait Characteristics and Joint Loading.
Running Performance
Running Economy (RE) value.
- It depends on the total mechanical work of the runner’s motion and also how efficiently the runner is able to store and release elastic energy in tendons and muscles (“elastic exchange”).
- Less work and more elastic exchange gives better RE.
- The stride parameters given in the Running Performance page all have impact on work and elastic exchange and they are evaluated in relation to long distance elite performance.
- The target is to minimize RE and a start rating guides you in the right direction.
The Gait Characteristics
- Detailed information about the runner’s kinematics in the sagittal and frontal planes.
- Large asymmetries or extreme parameter values are signs if abnormal gait which can increase the risk of injuries.
- All parameter data are put in context by relating to elite performance or the normal population.
More than 50% of all runners get injured each year and 50 % of the injuries involve the knee.
While there may be many contributing factors to the development of an injury, it is ultimately the load applied to the lower limbs that is the trigger.
No matter how experienced you are, there is no way to anticipate the loading level by visual inspection or video analysis.
Joint Loading
- Inverse dynamics which yield the net forces and moments acting on a joint.
- Focus is on the knee and hip joints.
- To assess if a joint loading variable may be harmful, it is compared with normative data from over 600 runners who have done the test.
- In addition, a built-in guide helps you to relate the joint loading variables to specific stride parameters.
- This allows you to make targeted stride corrections to reduce a specific force or moment from harmful level to normal.
3D Clinical Gait
3D Clinical Gait system provides a standard set of gait parameters in which most pathological conditions are reflected.
Clinicians can therefore use it to efficiently screen for a variety of conditions and to follow up on corrective measures.
Features:
- All relevant gait parameters from the standard work “Gait Analysis: Normal and Pathological Function” by Jacquelin Perry
- Center-of-mass trajectory in all three anatomical planes
- Frontal plane hip and knee joint moments and angles
- Sagittal plane hip and knee angles
- Temporal and spatial stride variability parameters
- Normative reference data
- Before-after test overlay
