Development of predictive models for the estimation of the probability of suffering fear of falling and other fall risk factors based on posturograph…
2016
Falls pose an important problem for older adults. Balance training is one of the main prevention strategies, but there is a lack of objective measurement methods that would allow the effectiveness of the treatments employed to be assessed. This study aimed to analyse the relationship between posturographic parameters and risk factors associated with falling, including the fear of falling (FoF). Forty-one healthy community-dwelling older adults were surveyed on their perception of problems considered to be fall risk factors. Balance measurement with posturography was performed. The relationships between risk factors and falls and risk factors and posturography were analysed by means of cross…
Influence of age, gender and obesity on pressure discomfort threshold of the foot: A cross-sectional study
2021
[EN] Background: Foot pain is a highly prevalent health problem for which measures such as a pattern of Pressure Discomfort Threshold of the foot plantar surface can provide valuable information for orthosis design. This study aimed to describe such pattern as a tool for the assessment of painful conditions of the feet and to analyse how it modifies according to age, gender and obesity. Methods: A cross-sectional study was performed with participants allocated in: Group 1 people aged 20 to 35 years, Group 2 aged 50 to 65 years and Group 3 aged over 65. Pressure Discomfort Threshold on twelve points of the foot plantar surface was measured with an adapted manual dynamometer. Inferential anal…
Examination of the risk factors associated with injured recreational padel players in Spain.
2017
BACKGROUND: Padel (called paddle in North America) is a relatively new racquet sport, with steady participation increases over the past 50 years. However, there is a need for data examining injury and associated risk factors. The study examined how intrinsic (e.g. age and sex) and extrinsic factors (e.g. padel participation and equipment) were associated with injury in recreational padel players. METHODS: A self-administered questionnaire completed by 80 recreational padel players between September 2014 and March 2015 acquired data on: respondent demographics and padel-related activities; the number of injuries within the past year; characteristics of the last injury sustained; and extrinsi…
Determination of the Optimal Saddle Height for Leisure Cycling (P188)
2008
Several studies have been done on road racing cycling and triathlon to determine the optimal saddle height (LINF) in terms of efficiency. However, cycling is becoming nowadays not only a popular sport but also a mass mean of transport were comfort takes priority over efficiency. The aim of this study is to determine an optimal saddle height (LINF) to improve comfort in leisure cycling. Five male subjects (height mean=172.2 cm, std=1.34 cm; crotch height mean=81.25cm, std=0.88cm) tested 9 prototypes of the company ORBEA with 3 levels of LINF. The test consisted in one hour cycling in lab conditions and four different techniques were used to evaluate the LINF: 3-D movement analysis was used t…
Quantifying Mean Shape and Variability of Footprints Using Mean Sets
2005
This paper1 presents an application of several definitions of a mean set for use in footwear design. For a given size, footprint pressure images corresponding to different individuals constitute our raw data. Appropriate footwear design needs to have knowledge of some kind of typical footprint. Former methods based on contour relevant points are highly sensitive to contour noise; moreover, they lack repeatability because of the need for the intervention of human designers. The method proposed in this paper is based on using mean sets on the thresholded images of the pressure footprints. Three definitions are used, two of them from Vorob’ev and Baddeley-Molchanov and one morphological mean p…
