“…In a study by O'Sullivan et al (34) aimed to determine the correlation between accelerometry and clinical patterns (Berg Balance Scale and the TUG test), to characterize accelerometer responses and acceleration patterns between fallers and non-fallers, the authors report that the Berg Balance Scale, tends to be subjective, while the TUG quantifies a functional impairment of the individual, but it requires a subjective evaluation to balance the assessment. Other alternatives require sophisticated and expensive equipment, therefore, the accelerometer is a potential solution to the problem, reaching the conclusion that it was the first type study which showed a high correlation between the instruments and accelerometry can also distinguish between stabilizing responses to different equilibrium conditions, proving to be an efficient alternative, quantitatively measuring the balance of the elderly.…”

Introduction The aging process produces functional and structural deficits in the body, among these changes we highlight the changes in balance. Objective This study aims to compare the computed photogrammetry and accelerometer to assess static balance in the elderly. Methods This was an observational, cross-sectional study. The study included 112 female subjects participating in a mothers club, where the balance assessment was performed using computerized photogrammetry and accelerometer. Results Average age 70.3 ± 5.8 [60-79] years, with the majority of the sample (47.3%) consisted of elderly widows, followed by 41.1% of married elderly. Most of the sample (73.2%) reported not working, eighty-six percent of the sample reported not having suffered falls in the last year. The vast majority of elderly studied (93.8%) reported not having suffered fracture episode and 6.3% reported having suffered fracture episode in the last three months, 75% of the sample owned anteriorization trunk, 63% had previous oscillation trunk and 37% had subsequent oscillation. Conclusion There were significant direct and a moderate to good between the measurements obtained in photogrammetry and triaxial accelerometer correlations.

“…No requieren el uso equipo especializado y los resultados son inmediatos. Sin embargo, existe interés por eliminar la subjetividad de estas pruebas [1,3]. También existen pruebas cuantitativas que determinan el riesgo de caída a partir de las características temporales del balanceo.…”

“…Es decir, su CoP estará contenido dentro de unárea menor [4]. Buscando medir el balanceo de los pacientes se han examinado métricas basadas tanto en el CoM como en el CoP tratando de relacionarlo con el riesgo de caída y las evaluaciones BBS y TUG [3,[5][6][7]. Algunas de estas pruebas requieren el uso de plataformas de fuerza de alto costo [5], de acceleróme-tros [3,6] o de cámaras [7,8].…”

“…Una vez establecidos los modelos SESC personalizados se pidió a los pacientes mantener posturas quietas sobre la plataforma de fuerza con ojos abiertos y cerrados así como con apoyos dobles y sencillos y se calculó la velocidad del CoM estimado y el CoP medido [5,6]. Potencialmente, el análisis de la velocidad del CoM personalizado permitiría la aplicación de pruebas posturográficas, sin marcadores, con sensores de bajo costo [3] y sin necesidad de plataformas instrumentadas o sensores fijos al cuerpo, incrementando las herramienta de diagnóstico disponibles para los tereapeutas.…”

Resumen-Se investiga el posible uso de la posición personalizada del centro de masa (CoM) obtenida mediante el método Statically Equivalent Serial Chain (SESC) para evaluar el equilibrio de un sujeto en el contexto clínico. Se calculó la velocidad del CoM para cuatro tareas de posturografía: doble apoyo con ojos abiertos, doble apoyo con ojos cerrados, apoyo sencillo con ojos abiertos y apoyo sencillo con ojos cerrados. Las velocidades calculadas se comparan con la velocidad del centro de presión (CoP). La cinemática de los sujetos fue medida con una cámara Kinect mientras que el CoP se obtuvo mediante una plataforma Wii Balance Board. Un total de 6 pacientes (4 mujeres y 2 hombres, 51.5±12.8 años, 1.57±0.09 m y 64.4±7.3 kg) con un historial médico variado fueron incluidos en el estudio. Los resultados preliminares no descartan al CoM personalizado para la evaluación rápida del equilibrio cuando una superficie instrumentada no se encuentre disponible.

Background Leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation (LBSL) is a rare leukodystrophy with motor impairment due to biallelic mutations in DARS2, which encodes mitochondrial aspartyl tRNA synthetase. Progressive ataxia is the primary feature. Objective The study objective is to determine the feasibility of remotely collecting quantitative gait and balance measures in LBSL. Methods The study design uses wearable accelerometers and the scale for the assessment and rating of ataxia (SARA) scale to assess gait and postural sway in LBSL and control participants' homes through video conferencing. Results Lateral step variability (LSV), which indicates stride variability, and elevation of the step at mid‐swing are increased for LBSL patients during brief walking tests. During stance with the eyes closed, LBSL participants show rapid accelerations and decelerations of body movement covering a large sway area and path. Both the LSV and sway area during stance with the feet together and eyes closed correlate strongly with the SARA. Conclusions Wearable accelerometers are valid and sensitive for detecting ataxia in LBSL patients during remote assessments. The finding of large increases in the sway area during stance with the eyes closed is intriguing since dorsal column dysfunction is universally seen in LBSL. This approach can be applied to related rare diseases that feature ataxia.
