Santrauka:
Šiuo tyrimu siekta nustatyti ar kūno masė turi įtakos skausmo, kelio sąnario funkcijos ir pusiausvyros pokyčiams po kelio sąnario endoprotezavimo. Tiriamieji – 60 – 75 metų amžiaus asmenys, kuriems pirmą kartą atliktas visiškas kelio sąnario endoprotezavimas dėl osteoartrito, bent 6 mėnesius jautę pastovų kelio skausmą ir neturėję gretutinių susirgimų, galinčių turėti įtakos tyrimo duomenimis. Naudoti metodai: antropometriniai duomenys, goniometrija, modifikuota medicininių tyrimų tarybos skalė, VAS skausmo skalė, „stotis ir eiti“ bei funkcinis siekimo testas.
Description:
Osteoarthritis is the most common reason for knee joint arthroplasty (Gademan et. al., 2016). Its main risk factor is obesity (Litwic et. al., 2013). According to world health organisation (WHO) 59,6 percent of adults in Lithuania had 25 kg/m^2 or greater body mass index (BMI) in year 2016. Studies shows that obesity is associated with a higher probability of infection (Watts et. al.., 2016; Dobner and Kaser, 2017) and risk of falling (Madigan et. al., 2014). People with high level of obesity have a higher revision rate than people with normal body mass (Boyce et. al., 2019).
The aim of the research: to determine the influence of body mass on the change in knee function and balance after knee replacement.
Goals: 1. Evaluate body mass, knee function, pain and balance of individuals after knee joint replacement at the beginning and end of the study. 2. Identify body mass relationships with knee function, pain and balance changes after knee joint replacement.
Methods: questionnaire for subject selection; anthropometric measures for BMI calculation; knee joint function characterization by visual analog scale (VAS) for pain evaluation, goniometry for knee joint range of motion evaluation and modified medical research council grade for muscle strength evaluation; timed “up and go” and functional reach tests for balance evaluation. Statistic analysis of data performed by IBM SPSS program, diagrams and tables composed using Microsoft Office Excel 2007.
Contingent: subjects aged 60 – 75 years old who underwent knee joint replacement for osteoarthritis and felt constant knee paint for at least 6 months.
Conclusions: 1. Body mass and BMI of subjects after total knee replacement changed insignificantly; knee joint flexion, extension and total range of motion significantly increased; muscle strength of knee flexion and extension significantly increased; balance significantly increased. 2. Relationships between body mass, knee joint function, pain and balance of subjects after total knee replacement were not found.
