Study of the relation between body weight and functional limitations and pain in patients with knee osteoarthritis

Abstract

Objective To assess the influence of the body weight in functional capacity and pain of adult and elderly individuals with knee osteoarthritis.Methods The sample consisted of 107 adult and elderly patients with knee osteoarthritis divided into two groups (adequate weight/adiposity and excessive weight/adiposity) according to body mass index and percent of body fat mass, assessed by electric bioimpedance. Subjects were evaluated for functional mobility (Timed Up and Go Test), pain, stiffness and function (Western Ontario and MacMaster Universities Osteoarthritis Index − WOMAC), pain intensity (Visual Analogue Scale − VAS) and pressure pain tolerance threshold (algometry in vastus medialis and vastus lateralis muscles). Data were analyzed with Statistical Package of the Social Sciences, version 22 for Windows. Comparisons between groups were made through Student’s t test, with significance level set at 5%.Results There was predominance of females in the sample (81.3%), and mean age was 61.8±10.1 years. When dividing the sample by both body mass index and adiposity, 89.7% of them had weight/adiposity excess, and 59.8% were obese. There was no difference between groups regarding age, pain intensity, pressure pain tolerance threshold, functional mobility, stiffness and function. However, pain (WOMAC) was higher (p=0.05) in the group of patients with weight or adiposity excess, and pain perception according to VAS was worse in the group of obese patients (p=0.05).Conclusion Excessive weight had negative impact in patients with osteoarthritis, increasing pain assessed by WOMAC or VAS, although no differences were observed in functionality and pressure pain tolerance.

Efficacy of Methotrexate on Pain Severity Reduction and Improvement of Quality of Life in Patients with Moderate to Severe Knee Osteoarthritis

“…Several studies have assessed the effect of weight loss and physical function on knee OA patients (21-23). Weight loss using aerobic exercises as well as proper diet are recommended in guidelines for knee OA patients.…”

Degeneration grade of a femoropatellar joint and functional status of a knee joint

“…The degenerative changes within the joint cartilage depend on age [6,11,13]. Pop et al by analyzing occurrence of gonarthrosis, they found that its frequency increases with age [14].…”

Presença De Assimetrias Posturais E Dores Musculoesqueléticas Em Membros Superiores De Indivíduos Adultos Com Excesso De Peso

“…Independente do grau da artrite na pesquisa de Rosales et al, (2014) foi constatado que o grupo avaliado em estudo que diminuiu o IMC apresentou melhora da dor e da função, e aqueles que o IMC aumentou teve uma piora tanto da dor quanto da função. Além do IMC, o excesso de adiposidade também pode estar associado a maior sensibilidade a dor (ALFIERI et al, 2017;PACCA et al, 2018).…”
