Correlation of Knee Osteoarthritis Patients' Characteristics and the Results of 30-Second Sit-to-Stand Test with Quality of Life

Abstract

Pain, joint stiffness, and difficulty performing activities like rising from sitting to standing are signs and symptoms of knee osteoarthritis (OA). These conditions are risk factors for limited mobility and lower quality of life. Knee OA is closely associated with age, women, obesity, and other characteristics. The study's objectives were to determine the correlation of knee OA patients' characteristics with functional mobility using the 30-second sit-to-stand test (30STS) and the correlation of functional mobility with quality of life using the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index. The research method was descriptive-analytic cross-sectional using medical records of 73 knee OA patients at the Medical Rehabilitation Clinic at Soreang Hospital, Muhammadiyah Hospital, Al Islam Hospital, Al-Ihsan Regional General Hospital West Java Province, Bandung, from March until August 2021. Patients' characteristics such as age (p=0.02), onset (p=0.01), OA grade (p=0,03), and knee deformity (p=0.04 ) have a negative correlation with functional mobility based on 30STS as well as functional mobility had a negative correlation with various aspects of quality of life, such as pain (p=0.03), stiffness (p=0.02), and functional limitation (p=0.00) subscales based on WOMAC index. Age, the onset of disease, OA grade, and knee deformity significantly correlate to functional immobility. Based on the WOMAC index, functional immobility correlates with the patient's quality of life.

“…As many as 14.3% of the subjects in the treatment group were patients with type 2 diabetes mellitus who were controlled, and there were 21.4% of the subjects in the treatment group and 35.7% of the subjects in the control group who had controlled hypertension (p-value= 0.313). This is related to the theory that states that the severity degree and risk of knee OA is not only influenced by age and the excess load that occurs on the knee joint due to obesity, but can also be influenced by metabolic factors such as diabetes mellitus and hypertension which affect vascularization and inflammatory response in the knee joint [10,11]. The 30STS assessment was carried out in the treatment group before and after weight training with the addition of BFR, as listed in Table 2.…”

“…Therefore, the purpose of this study was to evaluate the effect of LI-RT on the quadriceps femoris combined with BFR on lower extremity strength in patients with KOA measured by the 30STS test. (10) Currently having or history of lower extremity strengthening exercise program in the last 3 months, (11) Injuries, fractures, operations, or other musculoskeletal diseases in the lower extremities in the last 6 months, (12) Currently in therapy using Statin, chemotherapy treatment, or oral contraception, (13) Balance disorder, and (14) Impaired vision and hearing. The intervention group received LI-RT (30% 1-RM) combined with BFR, while the control group only received LI-RT.…”
