Sažetak
Objective: To test the method of 3D kinematic measurement of the Modified Thomas Test (MTT) and to compare it with standard 2D goniometric method. According to the authors' knowledge, a research including 3D kinematic measurement and analysis of the MTT has not yet been attempted. Methods: Research has been conducted in the Biomechanics Laboratory, Faculty of Kinesiology, during May 2016. The sample comprised of 54 male participants (108 lower limbs) age ranging between 19 and 27 years (mean age 21.8). A high degree of physical activity of participants was confirmed based on IPAQ. Kinematic features of MTT were evaluated using two objective methods: 2D goniometry (goniometer KaWe) and 3D kinematics (automatized optoelectronic kinematic measurement system ELITE, BTS Bioengineering Corp. with 8 cameras, frequency 100 Hz and 9 passive markers). Goniometric evaluation was performed by the examiner having 11 years of clinical experience. Sample of variables were four angles: knee flexion, hip extension, hip abduction and hip rotation. All measurements were conducted using two instruments simultaneously, bilaterally, taken initially after performing MTT. The tested limb was chosen by coin method, while non-tested extremity and lumbo-pelvic complex were stabilised with a strap. The procedure was repeated for the other limb. In total, 864 angles were measured, out of which 30 fell out from the experiment. Spearman's correlation coefficient was used in data processing. Results: Optoelectronic kinematic evaluation resulted with following mean values: knee flexion 52.72°±11.49° (goniometry=56.72° ±11.18°) ; hip extension 24.27°±8.55° (goniometry=10.07°±10.08°) ; hip abduction 8.2° ±6.44° (goniometry=7.84°±4.45°) ; external hip rotation 0.58°±4.38° (goniometry=0.98°±5.76°). Results assessed by two instruments were correlated and coefficient of r=0.91 was determined. Unexplained variance was comprised of systematic (differences in precision and marker positioning protocol of two methods, i.e. Trochanter vs. ASIS) and non-systematic sources of variability. Conclusion: Normative values for 4 angles at MTT were established. This study has shown high correlation between two types of measurement. Optoelectronic kinematic evaluation has shown superior with regard to goniometry due to the possibility of simultaneous measurement of angles and automated processing with expeditious reporting, making it a relevant modality for precise and comprehensive measurement of ROM.
