AB AIM: The aim of this study is to analyse the reliability, sensitivity and specificity of the parameterisation ofFRT using inertial sensors to record kinematic variables in subjects who have had a stroke. Our hypothesis isthat the IS will be reliable instruments for kinematic study of the FRT.METHODS: This is a cross-sectional study of 5 subjects over 65 years who suffer of stroke. During theexecution of Funtional Reach Test the subjects carried two inertial sensors, one was placed in the lumbarand the other in the trunk. After analysing the data obtained in the kinematic registration by inertial sensors anumber of direct and indirect variables were obtained. The variables extracted directly from FRT throughthe IS were distance, maximun angular lumbosacral/thoracic displacement, time maximun angularlumbosacral/thoracic displacement, time return starting position and total time. Using this data the speed andthe acceleration of each one of them were calculated. A descriptive analysis of all kinematic outcomesrecorded by the two inertial sensors was developed (trunk and lumbar) and the average range achieved in theFRT. Reliability measures were calculated by analysing the internal consistency the measures with 95%confidence interval of each outcome variable. The reliability was calculated in the functional reach and theoutcomes measured by the IS.RESULTS: The values in the the Functional Reach Test obtained in the present study (2.06 ± 12.75cm) aresimilar to those obtained in other studies with this population and in the same age range. Intrasubjectreliability values observed in the use of inertial sensors are all located above 0.820, ranging from 0.829 (timeB_C lumbar area) and 0.891 (A_B displacement of the trunk). Likewise, the observed intersubject valuesrange from 0.821 (Time B_C lumbar area) and 0.883 (B_C trunk displacement). On the other hand, thereliability of the FRT was 0.987 (0.983-0.992) and 0.983 (0.979-0.989) intersubject and intrasubjectrespectively.CONCLUSION: The main conclusion that can be reached is that the inertial sensors are a tool with excellentreliability, validity, sensitivity and specificity in the parameterisation of the Functional Reach Test in peoplewho have had a stroke.
