We developed an optoelectronic motion analysis protocol to measure anatomical and functional ranges of wrist motion in Colles’-type and scaphoid-type splints and casts. The protocol was used to study the restriction of wrist motion in casts and splints in ten healthy volunteers. Scaphoid-type casts were no more restrictive to wrist motion than Colles’-type casts, but casts were significantly more restrictive than removable splints. Removable splints were more restrictive than no immobilization. Results suggest there is no benefit in using scaphoid-type casts rather than Colles’-type casts to reduce wrist motion.

The purpose of this study was to develop a motion analysis protocol that allows the simultaneous assessment of all hand and finger joint movements. The objective was to demonstrate repeatability for future clinical applications in functional assessments. This study includes selection of marker positions, movement tasks, kinematic approaches and a comparison of the two most commonly used finger marker sets. By using a test–retest measurement of the range of motion in twenty healthy volunteers, the repeatability of the developed protocol was validated. Estimated errors of the presented method ranged from 1.2° to 6.4°. Finger joint angles derived from the marker set with two markers per segment showed better repeatability (3.7°) than with markers located on the joints (5.1°). Given the high repeatability found, the presented method appears to be suitable for clinical applications. For the fingers, measurement repeatability can be improved by using at least two markers per segment. Within this study, advanced kinematic approaches, such as functional determination of joint centers and axes, are applied to the analysis of hand movements. The provided standard values and estimate of the minimal detectable differences provide a valuable basis for meaningful data interpretation and may be used for future comparison with other protocols.

Objective: To evaluate the reproducibility of a modified optoelectronic volume measurement system (the volometer). Design: In the first part of the study healthy volunteers and one investigator were used to evaluate the intraobserver reproducibility; in the second part one healthy volunteer and different investigators were used to evaluate the interobserver reproducibility. Setting: Department of Dermatology, Academisch Ziekenhuis Maastrict, The Netherlands. Patients: Twenty healthy volunteers for the first part of the study; eight doctors and one healthy volunteer for the second part. Main outcome measures: Optoelectronic volume measurements on one leg over a standard distance of 40 cm and over 20 cm with the use of a laser pointer as calibration. A total of eight measurements were performed on each volunteer. The same procedure was performed by different investigators on one volunteer. Results: The modified optoelectronic measurement system with laser pointer calibration showed an improvement of the reproducibility of 27% in the intraobserver study. An improvement of 11% was found in the interobserver study. Conclusions: The modified optoelectronic volume measurement system (the volometer) provides a better reproducibility than the standard system. The instrument can be used for easy and rapid volume measurements in phlebological practice.
