Blinding
pain
The outcome assessor was blinded because the study was single blinded. He was an expert musculoskeletal physical therapist with 10 years of experience who completed baseline, one week, two weeks, and four weeks follow-up assessments. He was unaware of how the subjects were being treated. An expert musculoskeletal ultrasound specialist with more than eight years of expertise performed the musculoskeletal ultrasound. He performed MSKUS while the DN procedure was being done, and he was also not aware of the kind of treatment the patients received. He was in charge of conducting the MSKUS at the baseline, first, second-, and fourth-week follow-up.Participants were told that the needling intervention would cause moderate pain and that they should notify the researcher right away if the pain became intolerable during the procedure.Despite the fact that the physical therapist administering the treatments could not be blinded, he or she was asked not to disclose the patients' allocations during the intervention or follow-up sessions. Validity, reliability, and translation of the Lysholm scale had also been done for the current trial
