Does Prolonged Sitting Work Impacts Knee Joint Position Sense in Asymptomatic Women in age group of 50-55 years? A Comparative Study

The objective of this study was to compare differences in knee joint proprio-ception among asymptomatic working and nonworking women aged 50–55 years who sit for prolonged periods. Working women involved in sedentary jobs and age-matched nonwork-ing women from the community, all homemakers, were included in this study. A total of 113 women were screened, and 76 were included in the study (38 working and 38 nonworking). Joint position sense was measured with a standard goniometer at 45°, 60°, and 80° of knee range of motion from flexion to extension. Absolute error and relative error were recorded and analyzed. The average mean absolute error in the nonworking group was more than the average mean relative error in the working group for both the right and left knee. The nonworking women demonstrated more errors in knee joint position sense compared with working women at all angles of measurements.
