Summary

This pilot trial aimed to estimate preliminary clinical effects and to assess the feasibility of adding group-based pain neuroscience education (PNE) to exercise in women aged ≥60 years with medically diagnosed knee osteoarthritis and current knee pain. Participants were randomized to either 10 weeks of community-based exercise plus PNE or exercise alone. All participants attended weekly group exercise sessions, and those in the intervention group also participated in five in-person group-based PNE sessions lasting 30 minutes each. Physical fitness tests were administered, and participants completed questionnaires assessing disability, pain intensity, and pain neurophysiology knowledge.

Interventions

OTHER

Pain neuroscience education (PNE)

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.

OTHER

Exercise program

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.
