Second, motion capsule analysis measures the angle formed by the two bones being measured, which may not represent the "clinical" angle at the joint made by the soft tissue (i.e. with the knee in full extension [or 0°], the bones may be in slight hyper-extension relative to each other).
Concurrently, an infrared three-dimensional motion analysis system measured postures, six-degree-of-freedom force-torque sensors measured applied forces & torques, and surface electromyography measured muscle activity.
An active-marker infrared motion analysis system measured the kinematics of the fingertip, hand, forearm, upper arm and torso.
Finally, we chose a BMI cut-off of 35 kg/m to decrease skin movement artifact during walking, as is commonly used in motion analysis studies measuring the KAM [ 34- 36] to maximize gait data accuracy.
To examine the reliability and concurrent validity of an accelerometer compared with a three-dimensional (3D) motion analysis system for measuring the motor reaction time of the lower limbs, to validate a simple method for objective clinical assessment of movement onset.
There are concerns about the ability of standard motion analysis equipment and methods to measure this angle accurately (Scwartz 2004).
Three-dimensional motion analysis and surface electromyography measured wrist and thumb postures and forearm muscle activity, respectively.
Three-dimensional (3-D) motion analysis equipment is the gold standard for measuring medio-lateral knee position, but two-dimensional (2-D) motion analysis and visual observation and scoring are also used.
Angles of head, neck and trunk were measured by motion analysis in the sagittal plane and a cross-correlation analysis was performed on segments pairs.
