“…AutoPosturePD measures have been proven to be in agreement with those taken as the ground truth (i.e., those obtained with the NeuroPostureApp© [ 19 ]) and encourage the use of this novel tool to evaluate PS, lCC and tCC [ 30 ]. Indeed, correlation analysis and agreement between the two measures were very good [ 30 ], with systematic bias and the limit of agreements lower than the minimal detectable changes (

Axial postural abnormalities (aPA) are common features of Parkinson’s disease (PD) and manifest in over 20% of patients during the course of the disease. aPA form a spectrum of functional trunk misalignment, ranging from a typical Parkinsonian stooped posture to progressively greater degrees of spine deviation. Current research has not yet led to a sufficient understanding of pathophysiology and management of aPA in PD, partially due to lack of agreement on validated, user-friendly, automatic tools for measuring and analysing the differences in the degree of aPA, according to patients’ therapeutic conditions and tasks. In this context, human pose estimation (HPE) software based on deep learning could be a valid support as it automatically extrapolates spatial coordinates of the human skeleton keypoints from images or videos. Nevertheless, standard HPE platforms have two limitations that prevent their adoption in such a clinical practice. First, standard HPE keypoints are inconsistent with the keypoints needed to assess aPA (degrees and fulcrum). Second, aPA assessment either requires advanced RGB-D sensors or, when based on the processing of RGB images, they are most likely sensitive to the adopted camera and to the scene (e.g., sensor–subject distance, lighting, background–subject clothing contrast). This article presents a software that augments the human skeleton extrapolated by state-of-the-art HPE software from RGB pictures with exact bone points for posture evaluation through computer vision post-processing primitives. This article shows the software robustness and accuracy on the processing of 76 RGB images with different resolutions and sensor–subject distances from 55 PD patients with different degrees of anterior and lateral trunk flexion.

Introduction Shuai Shou Gong (SSG) is a type of Arm Swing Exercise (ASE) developed and practiced especially by older people in China for over one thousand years to maintain physical health and well-being. Until now the potential benefits of SSG have not been investigated in a Randomised Control Trial (RCT). Materials and methods Fifty six older women were recruited from each of two urban communities in Khon Kaen, Thailand. One community was randomly assigned as the Exercise Group (mean age 68.3 years, standard deviation 5.6 years) and the other as the Control Group (69.4 years, 4.4 years). The Exercise Group performed SSG for 40 minutes, three days per week for two months, whereas the Control Group maintained their usual daily life. Measurements of Posture (C7 to Wall Distance (C7WD), Standing Height (SH), Flexibility (Back Scratch of Left and Right arms (BSL and BSR) and Chair Sit and Reach of Left and Right legs (CSRL and CSRR), Gait (Timed Up and Go (TUG)), and Cognition (Barthel Activities of Daily Living Index (BADL) and Rosenberg Self Esteem Scale (RSES) questionnaires) were recorded for each group prior to, on day 1, week 4, and week 8 of the SSG training. Results The 8 week SSG training course produced a significant interaction between group and time for the combined set of all outcome measures (C7WD, SH, BSL, BSR, CSRL, CSRR, TUG, BADL, and BSES) (Modified ANOVA-Type Statistic (MATS) p-value < 0.001) and for the four categories of Posture, Flexibility, Gait, and Cognition (all Wald-Type Statistic (WTS) p-values < 0.05) and in all cases the changes in the Exercise Group were in the direction predicted to be beneficial. No significant interaction effect between time and group was found after either one session or four weeks of SSG training for any of the categories (all WTS p > 0.05) with significant effects only arising after eight weeks (all WTS p < 0.05). Thus although alterations were shown to be increasingly beneficial over time the minimum period required to produce a statistically significant benefit from performing SSG training was 8 weeks. For the Control Group no significant changes were identified for Posture, Flexibility and Cognition however a significant deterioration was observed in TUG (WTS p = 0.003). Conclusions SSG is a holistic, gentle, rhythmic, whole body sequence of movements that may be readily learned and enjoyed in a group setting and has been confirmed in an RCT study of older adult females to produce significant benefits in Posture, Flexibility, Gait and Cognition.

“…Uma alteração comumente observada nos sujeito com DP é a Forward Flexed Posture (FFP) ou postura fletida, que é definida como posição de anteriorização da cabeça, flexão anterior do tronco e a flexão do joelho, que pode resultar no deslocamento anterior do centro de gravidade e no alargamento da base de suporte, manifestada clinicamente como dificuldade para andar e girar, tendência a cair e dificuldade para girar ou incapacidade de girar na cama, podendo ser acompanhada de fraqueza dos extensores das costas e rigidez da coluna vertebral com ou sem dor associada [3,4,5]. Fisioterapia Brasil 2022;23(4):551-562 Uma revisão sistemática demonstrou que o DOP é um método válido e confiável para medir a FFP em sujeitos com DP demonstrando ser uma ferramenta prática e de fácil realização para a prática clínica, e com correlações com o avanço da doença [6].…”

“…Portanto, o objetivo do presente estudo foi investigar se a FFP está associada à independência funcional, mobilidade e qualidade de vida em sujeitos com DP. os joelhos; uma fita métrica foi usada para determinar a distância entre a parede e a protuberância occipital externa, sendo considerado normal o teste quando a cabeça encostar na parede [6,9]. Para avalia a independência funcional aplicou-se o Índice de Barthel é uma escala que determina o nível de independência de um indivíduo em relação ao desempenho das AVD básicas e fundamentais; os escores variaram de 0 a 100, sendo que 0 significa maior dependência e 100 total independência para realizar as tarefas do dia-a-dia e é válido e confiável para ser utilizado na população com DP [10].…”

Objetivo: Avaliar se a postura fletida (FFP) está associada à independência funcional, mobilidade e qualidade de vida em pacientes com doença de Parkinson (DP). Métodos: Estudo transversal e comparativo em Brasília/DF. Para avaliar a FFP, foi utilizado o teste de distância occipito-parede (DOP) e este foi comparado com medidas de força muscular (preensão palmar, extensão dorsal e membros inferiores), mobilidade funcional e qualidade de vida para verificar se há associações entre eles. Também foi verificado se havia correlação entre o estágio da doença, medido pela escala de Hoehn e Yahr (HY) e o tempo de diagnóstico. Resultados: Foram observadas correlações fortes entre DOP e HY, tempo de diagnóstico e qualidade de vida, e correlações moderadas entre marcadores de força muscular e mobilidade em indivíduos com DP. Conclusão: O FFP medida pelo DOP está fortemente associada com estágios de gravidade, tempo de diagnóstico e qualidade de vida e moderado com força muscular e mobilidade reduzida em pacientes com doença de Parkinson e representa uma medida simples e de baixo custo para a prática clínica.
