Table 1 Outcomes analysed with the CvMob software

Static

Romberg’s test

Oscillation speed

“Velo1 MED”^a

Mean of the total speed oscillation (X-axis + Y-axis)

To analyze ML oscillation, a marker will be placed on the occipital bone, at the midpoint of the imaginary line passing between the tips of each ear.

For AP oscillation, the marker will be located at the pterion, which is the junction between the parietal bones, frontal, sphenoid greater wing and squamous portion of the temporal bone.

“X” mean

“X” MED”^a

Representation of subject position in the video frame, on the X-axis.

Standard deviation

“X DESV”^a

Representation of balance stability of the subject. Higher values indicate a greater imbalance regarding the patient’s centre. This index will depend on the “X” MED value.

Oscillation amplitude

“X max-min”^a

Maximum amplitude of oscillation on the X-axis

Dynamic

Gait test

Step length

“X max-min”^a

Representation of step length.

Markers will be placed on the tip of internal and external malleolus. Markers are made of white foam rubber half-sphere stuck onto black tape, which allow for adherence to the patients’ skin.

Step height

“Y max-min”^a

Representation of step height.

Gait speed

“VeloX” MED^a

Representation of total gait speed.

Markers will be located at the pterion. They will also be used for static balance: Yellow circular stickers with 20 mm diameter.
