"The SARC-F scale has 5 questions which evaluate strength, assistance in ambulation, rising from a chair, stair climbing, and falls. The cut off point for predicting sarcopenia is score 4; 4 and more means risk of sarcopenia."

Low gait speed was defined as walking below than 0.8 meters per second.

the chair rise test (measures the strength of leg muscles), it measures the time taken for 5 times of rising from the sitting position without using arms, and was defined as low when the time taken was more than 15 seconds

Grip strength was measured with a hand-held dynamometer (Baseline, White Plains, New York, USA), and the cut-off thresholds were 32 kg for males and 22 kg for females

The visual analogue scale (VAS) was used for measuring general body pain severity, which was assessed from 0 (no pain) to 10 (worst possible pain)
