Heart Rate Variability Guided Physical Activity and Exercise Prescription in Individuals With Knee Osteoarthritis

Официальное название

Heart Rate Variability Guided Optimization of Physical Activity and Exercise Prescription to Enhance Rehabilitation Outcomes in Individuals With Knee Osteoarthritis (HOPE-OA Trial)

Обзор

The aim of this trial is to conduct a 12-week randomised controlled trial comparing an HRV-guided home exercise program with traditional home exercise program for individuals with knee osteoarthritis (KOA), followed by 24-week assessment. The trial employs a validated HRV sensor and the HRV4Training app to record daily HRV measurements, enabling personalized exercise intensity adjustments. Participants with high HRV are prescribed high-intensity exercises, while those with low HRV undertake low-intensity exercises. In contrast, the traditional exercise group follows a standardised program, progressing from low to high intensity over the 12-week period. The primary objective of this trial is to evaluate the effect of HRV-guided exercise on pain and functional disability in patients with KOA using validated outcome measures assessed at baseline, 12 weeks (post-intervention), and 24 weeks. Longitudinal semi-structured qualitative interviews at weeks 12 and 24 will explore participants' experiences and perceived barriers to exercise adherence. A mediation analysis will elucidate the physiological mechanisms underlying the efficacy of HRV-guided exercise. Secondary objectives include comparing HRV-guided and traditional home exercise programme in terms of exercise adherence, quality of life, sleep quality, self-efficacy, patient satisfaction, physical performance, balance, muscle strength, and lower limb biomechanics. Exploratory aims involve evaluating long-term effects (up to 24 weeks), examining associations between baseline HRV profiles and key outcomes, and determining the cost-effectiveness of HRV-guided exercise relative to traditional programme. The trial employs a robust methodological design, applying mixed-effects models and an intention-to-treat approach for data analysis.

Вмешательства

• Поведенческое HRV-guided home exercise prescription
  Participants in this group will follow the same exercise structure as the traditional home exercise group; however, their exercise program will be individualised according to daily HRV profiles. Exercise sessions will be performed three times per week for 12 weeks (36 sessions). All participants will conduct HRV measurements, starting one week before the intervention and continuing until its completion. HRV will be measured each morning immediately after awakening and bladder voiding, with parti
• Поведенческое Traditional Home Exercise
  Participants in this group will measure their HRV daily as described in the next section; however, these HRV measurements will not be used to guide their exercise prescription. Instead, participants will follow a standardized home exercise programme, conducted three sessions per week for 12 weeks (36 sessions). Each session will include a 5-10-minute warm-up, a main exercise component comprising aerobic, strengthening, and stretching exercises (e.g., stretching of lower extremity muscles includi
