NCT07565298

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • KOOS - Activities of Daily Living (KOOS-ADL)

    Self-reported disability during activities of daily living, measured using the Activities of Daily Living subscale of the Knee Injury and Osteoarthritis Outcome Score (KOOS). The KOOS is a knee-specific, self-administered questionnaire. The ADL subscale is scored from 0 to 100, with higher scores indicating better knee-related function.

    Baseline and immediately after the 10-week intervention period.

Secondary Outcomes (7)

  • KOOS - Pain Subscale

    Baseline and immediately after the 10-week intervention period.

  • KOOS - Symptoms Subscale

    Baseline and immediately after the 10-week intervention period.

  • KOOS - Sport and Recreation Function Subscale

    Baseline and immediately after the 10-week intervention period.

  • KOOS - Knee-related Quality of Life Subscale

    Baseline and immediately after the 10-week intervention period.

  • Pain intensity

    Baseline and immediately after the 10-week intervention period.

  • +2 more secondary outcomes

Other Outcomes (4)

  • Feasibility - Screening and Recruitment

    From enrollment to the end of the 10-week intervention.

  • Feasibility - Retention

    From enrollment to the end of the 10-week intervention.

  • Feasibility - Exercise Adherence

    From enrollment to the end of the 10-week intervention.

Study Arms (2)

Exercise plus Pain Neuroscience Education

EXPERIMENTAL

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.

Other: Pain neuroscience education (PNE)Other: Exercise program

Exercise-only group

ACTIVE COMPARATOR

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.

Other: Exercise program

Interventions

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.

Exercise plus Pain Neuroscience Education

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.

Model Details: Two-arm, parallel-group randomized controlled trial conducted between August and November 2024 at the San Joaquín Campus of Pontificia Universidad Católica de Chile, Santiago, Chile. Potentially eligible participants were identified during the initial Camina 60+KineUC sessions using the program questionnaire and functional assessment battery that included the Senior Fitness Test and the Four-Stage Balance Test. Participants who met the eligibility criteria and provided written informed consent were randomized in a 1:1 ratio to exercise plus pain neuroscience education (PNE) or exercise only. The allocation sequence was computer generated with OxMaR software, and age was used as the balancing factor. Allocation concealment was preserved by password-protected OxMaR access managed by GT.
