Evaluation of gait performance of knee osteoarthritis patients after total knee arthroplasty with different assistive devices

Abstract

Introduction: Nowadays Knee Osteoarthritis (KOA) affects a large percentage of the elderly, and one solution is to perform a Total Knee Arthroplasty (TKA). In this paper, one intends to study the gait and posture of these patients after the TKA, while walking with three assistive devices (ADs) (crutches, standard walker (SW) and rollator with forearm supports (RFS)). Methods: Eleven patients were evaluated in 2 phases: 5 days and 15 days after surgery. This evaluation was conducted with two inertial sensors, one attached to the operated leg ankle, to measure spatiotemporal parameters, and the other at the sacrum, to measure posture and fall risk-related parameters. Multivariate analysis of variance (MANOVA) with repeated measures was performed to detect group differences. Results: The MANOVA results show that all spatiotemporal parameters are significantly different (p<0.05) between the two phases of study. So, time has a significant influence on such parameters. In relation to the ADs, one observes that there are statistical significant effects on all spatiotemporal parameters, except for swing duration and step length (p>0.05). The interaction between time and ADs only affects significantly the velocity (p<0.05). In terms of fall risk parameters, time only significantly affects the antero-posterior direction (p<0.05) and ADs affects significantly root mean square in medio-lateral direction (p<0.05). In terms of interaction between time and ADs, there are no statistical significant differences. Conclusion: This study concludes that depending on the state of recovery of the patient, different ADs should be prescribed. On the overall, standard walker is good to give stability to the patient and RFS allows the patient to present a gait pattern closer to a natural gait.

Relationship between patients’ subjective involvement in postoperative rehabilitation and quality of life after arthroscopic treatment for osteoarthritic knee – cross-sectional study

“…Using assistive devices or walking aids, such as a cane or crutch, can reduce pain in patients with knee osteoarthritis [30]. Tereso et al revealed that different assistive devices should be prescribed depending on the state of recovery of the patient [31]. In the current study, respondents declared that their QoL in social support and social functioning decreased with the use of supporting devices, which may confirm that there is insufficient education in post-surgery management.…”

Uso de sensores inerciales en fisioterapia: Una aproximación a procesos de evaluación del movimiento humano

“…Burboa et al, (17) en su estudio, llevaron a cabo una relación entre los efectos del entrenamiento con respecto a los cambios en la angulación articular de miembros inferiores, encontrando que sí existe relación entre la fatiga generada en una sesión y los cambios en la angulación articular, siendo evidente la fiabilidad de las IMU en estas actividades. De igual manera, se emplearon como herramientas para la realización de evaluación de movimientos en diferentes entornos (13) , haciendo uso de ellos en gran medida, en estudios relacionados con los parámetros de la marcha, en la medición de variables como velocidad, posicionamiento de los miembros inferiores (10) , parámetros anormales de la marcha (11) y estimación de la rotación del movimiento de los usuarios para ser recreados y analizados con mayor profundidad en softwares de análisis de movimiento (51) .…”

Feature reduction with PCA/KPCA for gait classification with different assistive devices

“…The postural control parameters consist on a range of measures of COM displacement along with standard measures of accelerometer-derived postural sway, RMS acceleration (Doheny et al, 2012). Thus, the root mean square of V, AP, horizontal The data processing of the accelerometer and respective calculation of the presented features is explained in detail at Tereso et al (2015).…”
