In addition to the updates listed below, the following update was made with Nexus 2.12.1:
- CGM2 version updated to v3.4.5
- Foot position adjustments
- Foot scale updates to not calculate zero values
Dr Fabien Leboeuf (University of Salford) made the following updates to the Conventional Gait Model 2 (CGM2) that is included with Nexus.
- Ability to enter thigh rotation offset values that are read and applied to the model outputs.
- Ability to run CGM2 after running the Oxford Foot Model pipeline in Nexus.
- Ability to run CGM2 when scalar model outputs and other data are present.
- Corrected the head and thorax bones for scale and position, so that the upper body skeleton is scaled correctly in Vicon Polygon 4.x.
- Fixed chord function if the inputs include zeros (that is, gaps).
- Fixed an issue where no force plate was detected.
- Improved detection of missing markers and consequent adaptation of the CGM2 model. For example, if you're using a full body CGM2 marker set and during the walking trial an upper limb marker is missing, CGM2 automatically switches to a lower limb model and reports those model outputs (previously, you would have had no outputs).
- Removal of OpenMA (open source movement analysis library).
- Fixed an issue with moGap fill app when two subjects are detected.
- The data is checked for gaps, incorrect gait event sequences and swapped markers.
- Processing of data from foot strike gait events only.
- Development of a correction method for the thigh coordinate system, using Naaim et al. (2019) Correcting lower limb segment axis misalignment in gait analysis: A simple geometrical method. Gait & Posture, 72, 34-39. DOI: 10.1016/j.gaitpost.2019.05.013.
- Fixed an issue with EMG processing.
- Use of JSON file as a normative dataset.
- Fixed an issue with marker low-pass filtering.
- Events fixed in the btkAcquisition.
