Design outcomes

Primary

MeasureTime frame
Change in pain severity from baseline, measured using the pain subscale of the Oxford Knee Score (OKS), in participants with mild to moderate knee osteoarthritis receiving the intervention.Timepoint: Pain assessment using OKS at Week 1, Week 2, Week 3, and Week 4 following initiation of intervention.

Secondary

MeasureTime frame
Change in range of motion (ROM) of the affected knee joint from baseline, measured using goniometry. Change in pain intensity from baseline, assessed using the 10-point Visual Analogue Scale (VAS). Change in Knee Injury & Osteoarthritis Outcome Score (KOOS) from baseline, reflecting improvements in pain, symptoms, function, & quality of life. Frequency & quantity of rescue analgesic use, indicating additional pain management needs. Incidence of adverse events (AEs), treatment-emergent adverse events (TEAEs), & serious adverse events (SAEs) during the study period.Timepoint: Week 1, Week 2, Week 3, & Week 4 post-initiation of intervention for all secondary outcomes listed above.
