Another recent approach has been to precess the instrument's scan rotation, thus varying the angle between the drift vector and the slow-scan direction (most sensitive to drift).
In order to acquire large-sized surfaces, the imaging equipment will feature two main ingredients, namely, a multispectral IS acquisition device, which can be considered as the core of the instrument, and a rotation mechanism for easily covering large surface areas.
This beautifully crafted instrument subverts the rotation of the record player to produce a playfully dainty, hail-on-glass-like audible atmosphere.
Similarly, the foot rotation instrument appeared to provide a valid assessment of self-reported inward foot rotation (Table 1).
Similarly the foot rotation instrument was also found to have high sensitivity (0.92, 95%CI 0.83, 1.01) and specificity (0.96, 95%CI 0.93, 1.00).
This method was repeated using the foot rotation instrument except participants were required to look at their feet whilst walking instead of looking in a mirror.
Self-reported participant reproducibility of the foot rotation instrument was found to be excellent, with 87% of participants being able to reproduce exactly the results they reported in their questionnaires (κ 0.87; 95%CI 0.69, 1.06).
The Rottometer was judged to be a reliable measurement instrument concerning knee rotation at three different flexion angles (90°, 60° and 30°) at 6 and 9 Nm applied torques and as evaluated by the examiner's apprehension of end-feel.
The Rottometer was a reliable measurement instrument concerning knee rotation at the three different flexion angles (90°, 60° and 30°) with 6 and 9 Nm applied torques as well as the examiner's apprehension of end-feel.
The validity of both the knee malalignment and foot rotation instruments is shown in Table 1.
