Test cycles for the characterization of electrical drives devoted to wheelchair applications
2003
Today electrical wheelchairs are giving valuable increase of the quality of life of disabled people in developed countries. Despite the increasing diffusion of such an aid tool, specific standards for the characterization of their electric drives are not so developed as those available for urban electric vehicles. This paper presents a proposal for the test characterization of a wheelchair drive by means of test cycles with fixed speed trajectories. To this aim, the method, which is well known in the field of automobiles, has been purposely adapted and the obtained simulation results are satisfactory.
Influence of Training Load on Mood Disturbance at Sea Level and 3900 m Altitude: A Case Study of a Wheelchair Athlete
2018
The purpose of this case study was to investigate the influence of a training load (TL), oxygen saturation (SO2) and blood pressure (BP) on mood states in a wheelchair marathoner during (7 weeks at sea level (SL), 5 weeks at 3860 m altitude, 1 week returning to SL). TL was obtained with Foster’s equation while mood states were obtained with the Profile of Mood States Questionnaire (POMS). Furthermore, SO2 and BP were assessed upon wakening. SO2 (%) decreased at altitude, compared to SL (88.31 ± 2.46 vs. 98.52 ± 0.11) and increased until the last week at altitude (92.64 ± 1.12). Systolic pressure (SP) increased at altitude compared to pre-altitude (126.0 ± 5…
An Electrooculography based Human Machine Interface for wheelchair control
2019
International audience; This paper presents a novel single channel Electrooculography (EOG) based efficient Human–Machine Interface (HMI) for helping the individuals suffering from severe paralysis or motor degenerative diseases to regain mobility. In this study, we propose a robust system that generates control command using only one type of asynchronous eye activity (voluntary eye blink) to navigate the wheelchair without a need of graphical user interface. This work demonstrates a simple but robust and effective multi-level threshold strategy to generate control commands from multiple features associated with the single, double and triple voluntary eye blinks to control predefined action…
Professor of history of the art Felipe María Garín Ortiz of Taranco, between career and University and social
2013
En este trabajo se estudia la trayectoria universitaria y social del catedrático de Historia del Arte Felipe María Garín Ortiz de Taranco, para ver como desde la universidad se ayuda no sólo a la promoción universitaria sino también social de sus profesores. Con unos indicadores que analizan las distintas facetas, universitaria, movilidad académica, origen geográfico y social, cargos desempeñados, carrera profesional, política, distinciones…, valoramos el perfil del profesor universitario del siglo XX y sus contribuciones a la sociedad desde su disciplina. Felipe María Garín Ortiz de Taranco this paper explores the University and social trajectory of art history professor, to view as from t…
‘It’s not a part of me, but it is what it is’: the struggle of becoming en-wheeled after spinal cord injury
2019
Many people who experience spinal cord injury become long-term wheelchair users. This article addresses the process of becoming en-wheeled through the case example of a disabled man called Patrick.An intrinsic case study informed by posthumanist developments was used. Within this design, Patrick and his manual wheelchair were the entangled participants of the inquiry.Interviews and fieldwork observation with Patrick were conducted. Qualitative data were analysed using the posthumanist notion of 'assemblages'.The results illuminate Patrick's struggle of negotiating a new embodied selfhood that includes the wheelchair. Patrick engaged in ableist rehabilitation after spinal cord injury to recu…
Differences in kinematic and match-play demands between elite winning and losing wheelchair padel players
2020
We aimed to compare the match-play and kinematic demands of the translation and rotation movements of elite wheelchair padel players as a function of match results. Twenty-two elite male players were video-analysed with a two-dimensional direct linear transformation (DLT) -corrected video system across seven matches of a professional tournament. Distance, turns, changes of direction, linear and angular speed, acceleration and the players’ heart rate (HR) were recorded. Losing couples in wheelchair padel covered greater distances than winners (P <0.001; r = 0.024) and did so at a higher speed (P <0.001; r = 0.06), while making greater efforts by accelerating (P <0.001; ∅ = -0.021), braking (…
Key Physical Factors in the Serve Velocity of Male Professional Wheelchair Tennis Players
2021
The aim of this study was to identify the physical factors related to serve speed in male professional wheelchair tennis players (WT). Nine best nationally-ranked Spanish male wheelchair tennis players (38.35 ± 11.28 years, 63.77 ± 7.01 kg.) completed a neuromuscular test battery consisting of: isometric handgrip strength
Sagittal static imbalance in myelomeningocele patients: improvement in sitting ability by partial and total gibbus resection
2000
The progression of kyphosis in myelomeningocele is independent of skeletal growth and requires early operative correction and stabilization to prevent a loss of sitting ability. In severe cases, only vertebrectomy makes it possible to achieve correction, stability and skin-closure without tension. In 14 patients with myelomeningocele gibbus, kyphectomy was performed, removing two vertebral bodies on average. The average kyphosis angle decreased from 128 degrees to 81 degrees, enabling most of the patients to participate again in social life by restoring wheelchair mobility. Nevertheless, a significantly higher complication rate was found compared to other correctional operations, lengthenin…
Prospective associations of cardiovascular disease with physical performance and disability
2019
Background: Literature regarding cardiovascular disease (CVD) and incident physical performance limitations and disability in older people is equivocal. Aims: This study aimed to investigate whether CVD is longitudinally associated with incident physical performance limitations and disability in a large population-based sample. Methods: This was an 8‑year prospective study using data collected as part of the Osteoarthritis Initiative. Participants were community-dwelling adults with knee osteoarthritis or at high risk for this condition. Diagnosed CVD was self-reported. Physical performance was assessed with measures of chair stand time and gait speed, whereas disability was assessed with t…
