AB1400-HPR Muscle quality index in obese subjects with hip osteoarthritis

Abstract

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.

Muscle quality index and isometric strength in older adults with hip osteoarthritis

“…On the other hand, the results indicate that there is no association between body composition and MQI in the group with hip OA. The group of older adults without OA presented association between percentage of fat mass and BMI and MQI, results similar to those shown in a previous study where the MQI was only associated with a high body weight (Jerez, Machado & Cerda, 2018). These results are in contrast to this study’s findings, in which young subjects with a more significant amount of muscle mass have a higher performance in the sit-to-stand and therefore a higher MQI.…”

“…In relation to the findings of Loureiro, Mills & Barrett (2013), the highest force peak in subjects with OA was in hip flexion, but these numbers were lower than those found in healthy adults without OA and young adults. In this context, positive correlations have been found between MQI and peak force in flexion (Jerez, Machado & Cerda, 2018) in obese subjects with hip OA. The flexo-extension mechanism of the hip and knee plays a fundamental role in the activities of daily life, such as sit-to-stand time from a chair (Eitzen et al, 2014; Miura et al, 2018) and walking in subjects with hip OA (Foucher et al, 2012; Hurwitz et al, 1997).…”

“…Es así como una buena condición física, reflejada en un buen MQI como resultado del desarrollo de la fuerza, la potencia y el tamaño muscular (Barbat-Artigas et al, 2012) ha demostrado tener un rol fundamental en la prevención de enfermedades crónicas (Wolfe, 2006), relacionándose con una mejor calidad de vida (Sabido et al, 2016). En este sentido, bajos niveles de MQI, han sido asociados con una mayor probabilidad de muerte, una baja función física y fuerza muscular (Brown et al, 2016;Jerez et al, 2018). Asimismo, una disminución de MQI se encuentra altamente asociado a deficiencias de la capacidad funcional de la vida diaria (Jerez-Mayorga et al, 2019;Judd et al, 2014).…”
