Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary target variables are the posture parameters, which are recorded in three degrees of freedom (sagittal, frontal, and transverse planes) using either inertial motion analysis or optical methods, depending on the specific issue being investigated. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Secondary target variables for movement analysis include: orientation (degrees), position (mm), ground contact points (seconds) of body segments, and position data of the body's center of gravity. - When recording 4D upper body statics, the following measurement parameters are to be considered secondary target variables: pelvic torsion, shoulder torsion, height of the shoulder blades, height of the posterior anterior iliac spine, frontal and sagittal perpendicular of the spine, axial deviation, kyphosis and lordosis angles. - In planar pressure distribution, the following measurement parameters are to be regarded as secondary variables: average pressure load in the toe, ball, and heel areas, load on the longitudinal arch, gait line, force rate, and ground contact. - In addition, the following secondary parameters of upper airway ventilation are recorded: nasal airflow per nostril, oral airflow (if present), and the temporal course of respiratory flows in flow curves. | — |
