The intervention group received five group-based PNE sessions of 30 min each ((total dose = 150 min) delivered in person across the 10-week intervention period using digital presentations. The selected dose was informed by dose-response syntheses suggesting that 150-200 min of PNE may be associated with clinically relevant changes in psychosocial outcomes when combined with exercise. Sessions were delivered by four fourth-year physical therapy students trained in PNE and were based on The Knee Osteoarthritis Handbook (Noigroup©) and Dolor Crónico, una guía de ayuda para pacientes (Equipo DolorUC book). To support intervention fidelity, the student facilitators completed 5 days of 2hrs of training in PNE and communications skills before delivering the intervention, used a standardized slide deck and session script, and followed a prespecified checklist for each session.

The "Camina 60+KineUC" is a community-based program jointly delivered by the UC Older Adults Program and the Department of Physical Therapy of the Pontificia Universidad Católica de Chile. The program provides weekly group in-person sessions focused on strength, aerobic, balance, and flexibility exercises for adults aged 60 years and older, guided by monitors (physiotherapists and trained physiotherapy students), considering progression in movement complexity, or balance challenge according to tolerance, throughout the 10 weeks of the program.
