About this study

Rehabilitation remains important in the chronic phase after stroke or spinal cord injury, as meaningful improvements may still be achieved through intensive, goal-directed, and personalized training. INTeRAcT-bis is a follow-up study of the original INTeRAcT program, which consisted of a 3-week intensive rehabilitation intervention (90 therapy hours) combining conventional therapy, goal-directed training, self-management, and advanced rehabilitation technologies. The study has two main objectives: (1) to evaluate the long-term clinical and health economic effects of the original INTeRAcT program, and (2) to assess the clinical effects and implementation of a second intensive rehabilitation period ("boost"). Participants receive a personalized 3-week rehabilitation program targeting upper and/or lower limb impairments based on their individual goals. In addition to clinical and health economic outcomes, the study examines participant experiences and implementation factors to support a broader implementation of intensive rehabilitation in the future.

Read the detailed description

Stroke and spinal cord injury (SCI) frequently result in long-term disability, reduced health-related quality of life, and considerable societal and economic burden. While rehabilitation efforts have historically concentrated on the acute and subacute phases, the chronic phase is increasingly recognized as a period in which clinically meaningful improvements remain possible. Emerging evidence suggests that targeted rehabilitation can improve functional outcomes even years after injury. Yet, although improvement in functional capacity remains possible in the chronic phase after SCI and stroke, standard ambulatory care may not always provide the intensity, specialization, or participation- focused approach needed to address ongoing rehabilitation needs.

The INTeRAcT project, a phase 3 randomized controlled trial, was designed to address this gap by investigating whether a high-dose, technology-integrated rehabilitation programme, delivering 90 hours of personalised motor therapy over three weeks, could improve functional independence in daily living in patients with chronic stroke and SCI, and whether this improvement would translate into health-economic benefits as compared to usual care. The trial enrolled 100 participants, and its results are promising. Specifically, although functional performance in activities of daily living (ADL) did not differ significantly between groups immediately post- intervention, the intervention group showed superior outcomes at nine months compared to usual care. Secondary outcomes relating to personalized goals and health-related quality of life improved already after three weeks and were maintained at the nine-month follow-up. Despite these encouraging clinical results, the intervention was not cost-effective at the population level within the nine-month time horizon, with intervention delivery costs being identified as the main driver of this result.

Several important questions remain unanswered. First, the durability of clinical benefits beyond the original follow-up period is unknown. Second, it remains unclear whether a second intensive rehabilitation period ("boost") can produce additional clinically meaningful improvements. Third, further research is needed to evaluate the longer-term health-economic consequences of intensive rehabilitation and to identify factors influencing future implementation in routine clinical practice.

Research questions:

  1. What are the long-term clinical effects of the original INTeRAcT program in patients in the chronic phase after stroke or spinal cord injury?
  2. What is the long-term health economic impact and cost-effectiveness of the original INTeRAcT program?
  3. Does a second intensive, personalized 90-hour rehabilitation program lead to additional clinically meaningful improvements?
  4. How is this second boost program experienced and delivered in practice, and which factors are important for its future implementation?

Study Design

INTeRAcT-bis is a longitudinal follow-up study with an embedded rehabilitation boost intervention, health-economic evaluation, and process evaluation. The study includes participants who previously participated in the original INTeRAcT trial and completed the intensive rehabilitation program. Since all eligible participants have already received the original intervention, the present study does not include randomization and uses a longitudinal within-subject design.

Participants undergo a baseline assessment (T3), conducted approximately two years after the original intervention, followed by a three-week intensive rehabilitation boost program. Clinical assessments are repeated immediately after completion of the boost intervention (T4). In parallel, health-economic data and implementation-related data are collected.

Boost rehabilitation program

The intervention consists of 90 hours of intensive rehabilitation delivered over three consecutive weeks (30 hours per week; approximately 6 hours per weekday). During these three weeks, participants will engage in intensive, individualized, and task-specific rehabilitation with a strong focus on functional goals and activities relevant to daily life. The content of the therapy was developed for the INTeRAcT intervention and is described in detail in Coremans et al., 2026. The program will include the use of advanced rehabilitation technology where appropriate and will build on the same principles as the original INTeRAcT intervention, namely high-dose, personalized rehabilitation based on the goals and needs of the participant, combined with self-management support.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Functional Independence Measure (FIM)

    The Functional Independence Measure (FIM), which measures independence in daily functioning after stroke. The FIM consists of 18 items designed to assess to what extent a person needs assistance in performing activities of daily living safely and efficiently. The activities consist of a number of basic skills related to self-care, pelvic floor function, transfers, gait, communication and social abilities. The FIM has acceptable reliability and has been found valid in people with stroke.

    Min: 13; Max: 91; Higher = better

    Measured: Long-term follow-up / pre-boost assessment (approximately 3 years after the original INTeRAcT intervention) and Post-boost assessment (i.e., immediately after completion of the 3-week rehabilitation boost programme).

  2. Change in Spinal Cord Independence Measure (SCIM)

    Spinal Cord Independence Measure (SCIM), an assessment of achievements of daily function of patients with spinal cord lesions. The scale consists of 19 tasks organized in 3 subscales: self-care, respiration and sphincter management, and mobility. The SCIM is valid and reliable.

    Min: 0; Max: 100; Higher = better

    Measured: Long-term follow-up / pre-boost assessment (approximately 3 years after the original INTeRAcT intervention) and Post-boost assessment (i.e., immediately after completion of the 3-week rehabilitation boost programme).

  3. Change in Goal Attainment Scaling (GAS)

    Goal Attainment Scaling (GAS), is an individualised evaluation method. It is scored on an ordinal 5-point scale, which captures a person's individual treatment goal and is scored afterwards on the achievement of that treatment goal. The GAS can and will be used for both stroke and spinal cord injury.

    Min: -2; Max: +2; Higher = better

    Measured: Long-term follow-up / pre-boost assessment (approximately 3 years after the original INTeRAcT intervention) and Post-boost assessment (i.e., immediately after completion of the 3-week rehabilitation boost programme).

Secondary outcomes (5)
  1. Change in The Canadian Occupational Performance Measure (COPM)

    The Canadian Occupational Performance Measure (COPM), is an evidence-based outcome measure designed to capture a patient's self-perception of performance in everyday living, over time. This outcome can be used in both study populations.

    Min: 1; Max: 10; Higher = better

    Measured: Long-term follow-up / pre-boost assessment (approximately 3 years after the original INTeRAcT intervention) and Post-boost assessment (i.e., immediately after completion of the 3-week rehabilitation boost programme).

  2. Change in EQ-5D-5L

    EQ-5D-5L, measures quality of life at five levels of health (mobility, self-care, daily activities, pain/discomfort and anxiety/depression). From this, a weighted health index can be calculated for an individual or population. This scale can also be used for both populations.

    Min: 1; Max: 100; Higher = better

    Measured: Long-term follow-up / pre-boost assessment (approximately 3 years after the original INTeRAcT intervention) and Post-boost assessment (i.e., immediately after completion of the 3-week rehabilitation boost programme).

  3. Change in General Self-Efficacy Scale (GSES)

    Assesses one's overall confidence in one's own ability to cope with stressful or challenging situations.

    Min: 10; Max: 40; Higher = better

    Measured: Long-term follow-up / pre-boost assessment (approximately 3 years after the original INTeRAcT intervention) and Post-boost assessment (i.e., immediately after completion of the 3-week rehabilitation boost programme).

  4. Change in Function In Sitting Test (FIST)

    Evaluation of sitting balance that evaluates sensory, motor, proactive, reactive, and steady state balance factors.

    Min: 0; Max: 54; Higher = better

    Measured: Long-term follow-up / pre-boost assessment (approximately 3 years after the original INTeRAcT intervention) and Post-boost assessment (i.e., immediately after completion of the 3-week rehabilitation boost programme).

  5. Change in strength (Handheld dynamometer key movements)

    Muscle strength is measured using a handheld dynamometer for the following movements:

    • Shoulder flexion
    • Elbow extension
    • Wrist dorsiflexion
    • Knee extension
    • Ankle dorsiflexion

    Measured: Long-term follow-up / pre-boost assessment (approximately 3 years after the original INTeRAcT intervention) and Post-boost assessment (i.e., immediately after completion of the 3-week rehabilitation boost programme).
