The NPRS will be used to quantify LBP, and it exhibits good validity ranging from 0.79 to 0.95, as well as reliability ranging from 0.67 to 0.96(23). The scoring for NPRS involves a scale from 0 to 10, where 0 indicates no pain. The interpretation of scores is as follows: 0 to 3 for mild pain, 4 to 6 for moderate pain, and 7 to 10 for severe pain.

For measuring disability, Oswestry Disability Index will be utilized
