The Clinician Global Impression of change (CGIC) was
employed to assess improvement in patients’ overall condition
and was rated based on the clinical examination on
day 21 and 42. The scale range was from 0 to 7 [‘0’ = no
pain and ‘7’ = worst pain]. Assessment through clinical
examination was carried out by the designated orthopedic
consultant for presence or absence of joint tenderness,
crepitus, limitation of movement, subluxation of joint, and
muscle wasting.
