Mit akar kideríteni a vizsgálat

This project, conducted within the Department of Veterans Affairs Healthcare System (VHA), will test the effectiveness of an intervention to improve adherence to home exercise among Veterans receiving physical therapy (PT) for knee osteoarthritis (OA). The intervention, "Boosting Exercise Adherence in Knee Osteoarthritis" (BOOST-OA), has two phases. During the initiation phase (first 3 months of PT care), patients will receive tools and activities to address outcome expectations, action self-efficacy, goal-setting and monitoring. During the behavior maintenance phase (starting after PT care and continuing for 9 months), patients will receive health coaching calls that address satisfaction with outcomes, relapse prevention planning and independent monitoring. There are three main study aims: (1) examine improvements in patient outcomes, such as physical function, following BOOST-OA; (2) explore patient characteristics that lead to difference in reported improvements; and (3) interview participants and clinicians about their experience with BOOST-OA to inform future implementation.

A vizsgálat 2 csoportja

• Usual PT Care (UC)Már használt kezelés, összehasonlításként

  UC will be delivered by trained clinicians at participating sites. The study team will provide clinicians with guidance and training to standardize core aspects of physical therapy (PT), aligned with best practice recommendations. Clinicians must provide enrolled Veterans with at least 4 PT visits, spaced at least weekly so that Veterans can practice home exercise and receive guidance in exercise progression. All PT visits must be completed within 3 months.

• BOOST-OAA vizsgált kezelés

  BOOST-OA includes components that are integrated into physical therapy (PT) visits (concurrent), focused on behavior initiation, as well as components that occur after PT visits have ended (sequential), focused on behavior maintenance. Concurrent components will be delivered in conjunction with usual care PT visits. Clinicians must provide enrolled Veterans with at least 4 PT visits, spaced at least weekly. PT visits must be also completed within 3 months. Sequential components will be delivered by a health coach via phone or video. Health coach sessions will be conducted every other week for the first 2 months (months 4-5), monthly for an additional 3 months (months 6- 8), and every other month for the last 4 months (months 9-12; 9 total contacts). Calls will address strengthening and stretching exercises (≥3 times per week), as well as overall physical activity (e.g., minutes / steps).
