Adding Group-Based Pain Neuroscience Education to a Community Exercise Program for Older Women With Knee Osteoarthritis

27 aprile 2026 aggiornato da: Pontificia Universidad Catolica de Chile

Multidimensional Assessment of the Activities of the "Camina 60+" Program for the Promotion of Healthy Aging - Adding Group-Based Pain Neuroscience Education to a Community Exercise Program for Older Women With Knee Osteoarthritis: A Pilot Randomized Trial of Feasibility and Preliminary Effects.

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.

Panoramica dello studio

Descrizione dettagliata

Knee osteoarthritis (OA) is a highly prevalent and disabling condition in older adults, with the knee being the most commonly affected joint. In Chile, OA represents a substantial clinical and public health burden, particularly among women aged 60 years and older, who experience high rates of pain, disability, and loss of functional independence. Disability and pain are hallmark symptoms of knee OA and are strongly associated with reduced physical function and poorer quality of life in older women. Current clinical guidelines recommend education, self-management, and exercise as first-line treatments. Exercise therapy can improve pain and physical function in people with knee OA, but average effects are modest and individual responses vary. Pain in knee OA is increasingly understood within a biopsychosocial framework, suggesting that maladaptive pain beliefs contribute to persistent symptoms. Pain Neuroscience Education (PNE) may complement exercise by improving pain-related knowledge and psychological outcomes, although evidence-particularly for group-based delivery and disability outcomes in older women-remains limited. This study was implemented in the context of a training program called "Camina 60+KineUC", a community-based program jointly delivered by the UC Older Adults Program and the Department of Physical Therapy from Pontificia Universidad Católica de Chile. The program provides weekly group sessions focused on strength, aerobic, balance, and flexibility exercises for adults aged 60 years and older and is designed to promote healthy aging. The study was designed to assess feasibility and estimate preliminary between-group effect sizes rather than to make definitive efficacy conclusions.

Sperimentale: Exercise plus Pain Neuroscience Education
In addition to the 10-week Camina 60+KineUC exercise program, this group received five in-person group-based Pain Neuroscience Education (PNE) sessions lasting 30 minutes each. Sessions were delivered across the intervention period using standardized digital presentations, for a total dose aligned with evidence suggesting psychosocial benefits when PNE is combined with exercise. The intervention was delivered by four fourth-year physical therapy students trained in PNE, based on recognized educational resources. Intervention fidelity was ensured through prior training, use of standardized materials, and adherence to a prespecified session checklist.
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.
Comparatore attivo: Exercise-only group
Camina 60+KineUC exercise program for 10 weeks, which consists of group exercise sessions delivered weekly, in person, and includes strength, aerobic, balance, and flexibility exercises. Each exercise session lasted 60min and was delivered by the monitors of Camina60+. Sessions included warm-up, strengthening, aerobic training, balance, and flexibility. Progression across the 10-week intervention period was standardized by movement complexity, or balance challenge according to tolerance. After study completion, they were offered the same group-based PNE program provided to the intervention group.
