Plantar Pressure Differences Between Nordic Walking Techniques
2017
Abstract High plantar pressure has been associated with increased risk of injury. The characteristics of each physical activity determine the load on the lower limbs. The influence of Nordic Walking (NW) technique on plantar pressure is still unknown. The aim of this study was to analyze the differences between plantar pressure during NW with the Diagonal technique (DT) versus Alpha technique (AT) and compare them with the pressure obtained during normal walking (W). The normality and sphericity of the plantar pressure data were checked before performing a two-way repeated measures ANOVA in order to find differences between speeds (preferred, fast) and the gait (NW, W) as within-subject fac…
Effectiveness and Duration of Plantar Pressure Off-loading by Two Designs of Felt Padding: A Preliminary Study.
2019
Background: The aim of this study was to observe the pressure changes in the felt padding used to off-load pressure from the first metatarsal head, the effects obtained by different designs, and the loss of effectiveness over time. Method: With a study population of 17 persons, two types of 5-mm semicompressed felt padding were tested: one was C-shaped, with an aperture cutout at the first metatarsophalangeal joint, and the other was U-shaped. Pressures on the sole of the foot were evaluated with a platform pressure measurement system at three time points: before fitting the felt padding, immediately afterward, and 3 days later. Results: In terms of decreased mean pressure on the first met…
Parkinson's disease and segmental coordination during modified figure of eight walking turning task
2016
Turning while walking is problematic for individuals with Parkinson’s disease (PD). We hypothesized there would be instability and turning difficulty for the PD subjects while performing a complex motor skill task of the modified figure of eight (MFE) walking task. There were 26 subjects (10 males and 16 females) with clinical diagnosis of “idiopathic” PD and undergoing L-dopa treatment participating in this study. The PD subjects performed the clinical balance modified figure of eight (MFE) test. The 3-D positions of the head, trunk and pelvis were recorded and analyzed. The angular displacement and angular velocity of the head, trunk and pelvis were calculated. Counter-clockwise and clock…
Scurvy as an alarm bell of autistic spectrum disorder in the first world: A case report of a 3-year-old girl
2021
Patient: Female, 3-year-old Final Diagnosis: Scurvy and autistic spectrum disorder Symptoms: Bleeding gums • pain • petechia Medication: — Clinical Procedure: Haematochemical blood examinations • radiographic study Specialty: Endocrinology and Metabolic Objective: Rare disease Background: Scurvy secondary to deficiency of vitamin C is a rare condition in children. The polymorphism of clinical signs and symptoms makes scurvy diagnosis a challenge for the pediatrician. Case Report: A 3-year-old girl came to our observation because she refused to walk and to stand, she showed petechiae, follicular hyperkeratosis on the limbs, and bleeding gums. After a physical exam, laboratory tests, and X-ra…
2D simulation of wave-particle coupling inspired by walking droplets
2018
In recent years, a fluid dynamics phenomenon has been observed that shows interesting analogies with several quantum mechanical ones. Under specific experimental conditions, a liquid droplet released on a vibrating liquid persists in jumping, forming a localized wave-particle, and its behaviour resembles that of a de Broglie wave-particle. In this paper we discuss a simplified model for this phenomenon and the results of numerical fluid dynamics simulations implemented on the basis of the model. In spite of the relevant simplifying assumptions of our approach, we observe that a wave-droplet coupling is obtained and the droplet travels at nearly constant velocity, as it is observed in experi…

Abstract Manty M, Heinonen A, Leinonen R, Tormakangas T, Sakari-Rantala R, Hirvensalo M, von Bonsdorff MB, Rantanen T. Construct and predictive validity of a self-reported measure of preclinical mobility limitation. Objectives To validate self-reported preclinical mobility limitation concept and self-report assessment method against muscle power and walking speed, and to study the predictive validity of preclinical mobility limitation with respect to future risk of manifest mobility limitation. Design Observational prospective cohort study and cross-sectional analysis. Setting Research laboratory and community. Participants A total of 632 community-living (age range, 75−81y) women and men t…
Effects Of Whole Body Vibration In Patients With Chronic Obstructive Pulmonary Disease - A Randomized Controlled Trial
2012
Summary Introduction To date endurance and strength training are established and evidence-based exercise methods in patients with chronic obstructive pulmonary disease (COPD). There is an unmet need for further research in new and complementary exercise modalities. Additional whole body vibration training during pulmonary rehabilitation may be such a new approach that has not yet been investigated in patients with COPD. Methods Eighty-two patients (65 ± 9 yrs, FEV 1 pred. 38 ± 11%, female 51%) with COPD in GOLD stage III to IV assessed for a 3-week inpatient multidisciplinary rehabilitation program were on top randomly assigned to one of two intervention groups: (1) 3 × 3 min of bilateral d…
Should we use gait speed in COPD, FEV 1 in frailty and dyspnoea in both?
2016
Frailty is a progressive physiological decline in multiple organ systems marked by loss of function, loss of physiological reserve and increased vulnerability to disease [1]. Biological (inflammation and loss of hormones), clinical ( e.g. sarcopenia and osteoporosis) and social factors are involved in frailty onset, evolution and prognosis [2, 3]. Links between frailty, dyspnoea and chronic respiratory diseases represent a novel and practical approach
Integrative Biomimetics of Autonomous Hexapedal Locomotion
2019
Despite substantial advances in many different fields of neurorobotics in general, and biomimetic robots in particular, a key challenge is the integration of concepts: to collate and combine research on disparate and conceptually disjunct research areas in the neurosciences and engineering sciences. We claim that the development of suitable robotic integration platforms is of particular relevance to make such integration of concepts work in practice. Here, we provide an example for a hexapod robotic integration platform for autonomous locomotion. In a sequence of six focus sections dealing with aspects of intelligent, embodied motor control in insects and multipedal robots-ranging from comp…
A neural network approach to movement pattern analysis.
2004
Movements are time-dependent processes and so can be modelled by time-series of coordinates: E.g., each articulation has geometric coordinates; the set of the coordinates of the relevant articulations build a high-dimensional configuration. These configurations--or "patterns"--give reason for analysing movements by means of neural networks: The Kohonen Feature Map (KFM) is a special type of neural network, which (after having been coined by training with appropriate pattern samples) is able to recognize single patterns as members of pattern clusters. This way, for example, the particular configurations of a given movement can be identified as belonging to respective configuration clusters, …
