BackgroundObese older adults with hip osteoarthritis suffer a progressive loss of neuromuscular function affecting their activities of daily living.ObjectivesThe objective of this study is to determine the behaviour of the muscular quality index in obese subjects with osteoarthritis and to compare the manifestations of strength and anthropometric variables with control subjects.MethodsThirty-two subjects (4 men and 28 women, 66.2±5.2 years of age, 159.2±7.5 cm, 71.5±11.7 kg) were evaluated. 14 subjects suffered osteoarthritis. Muscle circumference, limb length, body mass and sit and stand test were evaluated, in addition to the maximal voluntary isometric contraction in hip flexion and extension movements.ResultsThe osteoarthritis group presented obesity (p=0.037). The muscle quality index of the osteoarthritis group correlated with the weight (p=0.776**), with maximum peak strength in flexion (p=0.552*) and average maximal strength (p=0.574*). In the control group the muscle quality index correlated with: weight (p=0.689**), muscle circumference (p=0.571*), maximum peak strength in extension (p=0.534*), average peak strength in extension (p=0,523*), average maximal strength in extension (p=0.509*) and maximum impulse in extension (p=0.508*).ConclusionsThe muscle quality index is a useful tool to measure muscle quality in the healthy population, but is not clear enough for obese subjects with osteoarthritis, so it is necessary to perform future studies to determine their behaviour.References[1] Fragala MS, Kenny AM, Kuchel GA.

The refurbishing of a longitudinal strip on an open floor of an existing building, destined to the accounts area of the offices of a publicity agency, is resolved by means of a mobile furniture-wall that is used along the entire extension of the refurbished area. Storage orders and defines the work area. La habilitación de una franja longitudinal de una planta libre en un edificio existente, destinada a las áreas de cuentas de las oficinas de una agencia de publicidad, se resuelve a partir de un muro-mueble móvil que recorre toda la extensión del área intervenida. El almacenamiento ordena y define el lugar de trabajo.
