Overweight Not Associated with Q-Angle in the Elderly
Main Article Content
Abstract
Background: Overweight can affect the quadriceps angle (Q-angle), which plays an important role in knee balance and stability, especially in the elderly. Q-angle imbalance has the potential to cause musculoskeletal disorders. This study aims to determine the relationship between overweight and Q-angle in the elderly.
Methods: This study used a cross-sectional design and was conducted on December 1 and 5, 2022, at the Dr. Soetomo Surabaya Hospital Retirees Association. The sampling technique used purposive sampling with a sample size of 54 elderly people (14 men and 40 women) aged 60–75 years. Data were collected using observation sheets and measurements of height, weight, and Q-angle in the supine position. Data analysis used Spearman's correlation test because the data were not normally distributed.
Results: The average age of respondents was 64.41±3.77 years with a body mass index (BMI) of 27.41±1.22 kg/m² and an average Q-angle of 17.78±3.42°. The correlation test results showed a p-value >0.05 (r=0.196), indicating no significant relationship between overweight and Q-angle in the elderly.
Conclusion: There is no relationship between overweight and Q-angle in the elderly. These results indicate that the measurement position, activities prior to measurement, and physical characteristics of the elderly can affect Q-angle values. The researchers suggest that Q-angle examinations in the elderly be performed in a functional position (standing) and with relaxed muscles.
