Purpose: The purpose of this study was to determine the reliability of optoelectronic motion capture analysis to determine the hip range of motion.
Materials and Methods: Fifteen recreationally active male participants (age 26.67 + 4.84 years). Measurement values were got by performing the optoelectronic motion capture analysis on subjects with sensors attached to their bodies. The Root mean square error (RMSE) was used to determine the accuracy of optoelectronic motion capture analysis values got by the assessors and it was compared with the standard hip range of motion.
Results: The Root mean square error of optoelectronic measurements of the hip range of motion was calculated in reference to standard values. The left sided external rotation showed the highest deviation from the standard values (26.57). Hip adduction measurements using optoelectronic motion capture analysis were least deviated from standards (right – 29.70 and left – 29.70).
Conclusion: The optoelectronic motion capture analysis is a reliable tool to calculate the hip range of motion. But, further well designed studies need to be done in order to eliminate the limitations found in our study.
