Tracking Movement in Pediatric Rehabilitation: Best Practices for Wearable Data Collection

1. Introduction

Physical activity tracking plays a critical role in pediatric rehabilitation, helping clinicians and researchers monitor recovery progress, therapy effectiveness, and functional improvements. Movement-based interventions are widely used in neurological, orthopedic, and cardiorespiratory rehabilitation, where tracking mobility levels can provide valuable feedback on a child’s recovery trajectory.

Wearable devices offer an objective, non-invasive way to assess movement patterns in children undergoing rehabilitation. However, measuring activity in this population presents unique challenges, including variable mobility, inconsistent compliance, and the need for devices that accommodate assistive equipment. Researchers and clinicians must select the right measurement tools, optimize data collection strategies, and ensure usability in both clinical and home settings.

This guide outlines best practices for using wearable devices in pediatric rehabilitation, focusing on device selection, data collection methods, and movement data interpretation to support recovery.

2. Key Considerations for Measuring Movement in Pediatric Rehabilitation

Tracking movement in pediatric rehabilitation requires a tailored approach that accounts for different medical conditions, therapy goals, and environmental factors. Unlike general physical activity studies, rehabilitation research focuses on functional recovery and mobility restoration, requiring more precise movement analysis.

• Differences in rehabilitation goals by condition
  • Neurological conditions (e.g., cerebral palsy, brain injuries) emphasize motor control, coordination, and gait stability.
  • Orthopedic conditions (e.g., fractures, post-surgical recovery) focus on weight-bearing activity and joint mobility.
  • Cardiorespiratory conditions (e.g., cystic fibrosis, congenital heart disease) require energy expenditure tracking and endurance assessment.
• Variability in mobility and movement patterns
  • Some children have irregular movement due to motor impairments, requiring customized data interpretation.
  • Others may use assistive devices such as crutches, walkers, or prosthetics, which affect traditional movement tracking algorithms.
• Rehabilitation setting considerations
  • Inpatient rehabilitation: Wearables may be used for continuous monitoring in a hospital setting, requiring real-time data access.
  • Outpatient/home-based rehabilitation: Devices must be easy to wear and sync remotely, as direct supervision is limited.

Understanding these factors helps in choosing the right measurement tools and ensuring movement tracking aligns with rehabilitation objectives.

3. Selecting the Right Wearable Devices for Pediatric Rehabilitation

Choosing the appropriate wearable technology for rehabilitation studies depends on the type of movement being assessed, the child’s mobility level, and the clinical setting. The ideal device should provide accurate movement data without interfering with therapy or causing discomfort.

Accelerometers

Accelerometers are widely used in pediatric rehabilitation to track general movement patterns, step counts, and sedentary time. They provide objective, real-time activity data without requiring manual input from participants.

• Best for: Assessing daily activity levels, gait patterns, and postural transitions.
• Device placement considerations:
  • Wrist-worn: High compliance but may misclassify non-locomotor movements as activity.
  • Waist-worn: More accurate for step counting and movement intensity but may be uncomfortable for children with mobility aids.
  • Thigh-worn: Best for detecting sitting, standing, and walking transitions, particularly in neurological rehabilitation.

Inertial Measurement Units (IMUs)

IMUs provide detailed motion tracking using a combination of accelerometers, gyroscopes, and magnetometers. These devices are especially useful for gait analysis and balance assessments.

• Best for: Studying joint angles, symmetry in movement, and rehabilitation progress.
• Limitations: More complex data processing is required, making them better suited for clinical rather than home-based monitoring.

Heart Rate Monitors (ECG vs. PPG)

Heart rate monitoring helps track exercise intensity and recovery capacity, particularly in children with cardiorespiratory conditions.

• ECG-based chest monitors offer high accuracy but may be less comfortable for extended wear.
• PPG-based wrist sensors are easier to wear but may be affected by motion artifacts, especially in highly active children.

Multi-Sensor Wearables

Some devices integrate accelerometry, heart rate, and muscle activity sensors to provide a more comprehensive view of rehabilitation progress.

• Useful for: Monitoring physiological responses to movement, fatigue levels, and muscle activation during therapy.
• Ideal for: Children recovering from neuromuscular conditions, post-surgical interventions, or chronic fatigue syndromes.

Selecting the right wearable depends on the rehabilitation goal, data accuracy needs, and patient comfort, ensuring seamless integration into therapy plans.

4. Best Practices for Data Collection in Rehabilitation Settings

Accurate movement tracking in pediatric rehabilitation requires consistent data collection methods that minimize burden while maximizing compliance. Since children undergoing rehabilitation may experience fatigue, discomfort, or variable mobility, researchers and clinicians must ensure that devices are worn correctly, data is captured consistently, and missing data is minimized.

Ensuring Device Comfort and Wearability

Children in rehabilitation often have sensory sensitivities, muscle weakness, or assistive devices, making wearability a critical factor in device selection. If a tracker is uncomfortable, restrictive, or interferes with therapy, children are less likely to wear it consistently.

• Lightweight, soft materials help prevent irritation, especially for children with skin sensitivities or post-surgical wounds.
• Adjustable straps and flexible fastenings allow devices to be securely worn without restricting movement or blood circulation.
• Placement options must accommodate assistive devices, such as walkers, orthotic braces, or prosthetics, to avoid interference.

Encouraging Compliance in Young Patients

Unlike adults, children may not fully understand the importance of wearing a device, especially if they find it inconvenient or unnecessary. Caregivers, therapists, and parents play a key role in ensuring consistent wear time.

• Engaging parents and therapists to remind children to wear and charge devices improves compliance.
• Providing visual progress tracking (e.g., graphs, dashboards) can help children see their improvements, boosting motivation.
• Using reward-based systems, such as stickers, certificates, or virtual badges, can encourage younger children to participate more actively.

Minimizing Data Loss in Home-Based Rehabilitation

Home-based rehabilitation studies pose additional challenges due to lack of direct supervision. Automatic data upload and structured follow-ups can help prevent missing data.

• Wearables with real-time cloud syncing eliminate the need for manual data downloads.
• Regular check-ins via phone calls or telehealth visits encourage families to maintain adherence.
• Having backup devices available ensures continuity in case of device loss or malfunction.

By optimizing comfort, engaging caregivers, and streamlining data collection, researchers can improve study reliability and clinical usefulness.

5. Interpreting Movement Data for Rehabilitation Progress

Wearable data provides objective insights into a child’s recovery, but correct interpretation is essential to ensure meaningful conclusions. Since rehabilitation focuses on gradual improvements rather than absolute movement counts, researchers must analyze trends over time, activity fluctuations, and therapy responses.

Setting Individualized Movement Targets

Standard physical activity guidelines may not apply to children in rehabilitation. Instead, personalized goals should be established based on pre-existing mobility levels, therapy objectives, and recovery timelines.

• Adjusting activity targets to match functional ability ensures realistic progress tracking.
• Tracking step count increases, movement consistency, and postural changes helps assess therapy effectiveness.
• Identifying safe activity thresholds prevents overexertion or fatigue-related setbacks.

Identifying Trends in Recovery

Tracking movement patterns over time helps clinicians determine whether a child is improving, plateauing, or regressing.

• Progressive increases in movement frequency indicate growing strength and endurance.
• Extended sedentary periods may suggest pain, discomfort, or lack of therapy engagement.
• Gait symmetry and balance metrics help monitor neuromuscular recovery in conditions like cerebral palsy or post-surgical rehabilitation.

Adjusting Therapy Plans Based on Wearable Data

Wearable movement data can be used to tailor therapy sessions by adapting exercise intensity, duration, and frequency.

• If movement levels remain low, therapists can introduce more engaging or varied exercises.
• If a child is exceeding activity targets, rehabilitation intensity can be adjusted to gradually increase difficulty.
• Clinicians can identify signs of overexertion or fatigue, ensuring recovery stays safe and sustainable.

By analyzing individualized movement trends, therapists can fine-tune rehabilitation strategies for optimal recovery outcomes.

6. Using Wearable Data to Enhance Rehabilitation Interventions

Beyond tracking movement, wearable data can be actively integrated into therapy programs to improve engagement, motivation, and long-term outcomes. By leveraging real-time feedback, gamification, and personalized goal-setting, clinicians can encourage children to participate more consistently in their rehabilitation programs.

Gamification and Engagement Strategies

Gamification techniques can make rehabilitation exercises more enjoyable, increasing motivation in younger patients.

• Interactive movement challenges, such as step goals or virtual races, encourage participation.
• Reward-based systems, where children earn points for achieving movement milestones, can make therapy more engaging.
• Augmented reality and mobile apps can turn movement exercises into interactive games, improving adherence.

Integrating Wearable Feedback into Therapy Sessions

Providing real-time movement tracking during therapy sessions allows therapists to adjust exercises dynamically and reinforce progress.

• Using wearable data to provide immediate feedback helps children understand how specific movements contribute to recovery.
• Linking movement tracking with rehabilitation assessments (e.g., balance tests, joint mobility scores) enables data-driven treatment adjustments.
• Comparing pre- and post-therapy movement patterns helps validate treatment effectiveness.

Long-Term Monitoring for Sustained Recovery

Tracking movement beyond the rehabilitation period can help determine whether functional improvements are maintained over time.

• Post-rehabilitation monitoring ensures children retain mobility gains after therapy ends.
• Identifying movement declines early allows clinicians to intervene before regressions occur.
• Supporting transition to independent physical activity helps children maintain active lifestyles post-recovery.

By incorporating wearable technology into active therapy plans, rehabilitation programs can be more engaging, data-driven, and personalized for each child’s recovery needs.
