Using Wearable Devices to Monitor Recovery in Pediatric Patients After Surgery

1. Introduction

Recovering from surgery is a critical period for children, requiring careful monitoring of movement, pain levels, and functional mobility. Post-surgical physical activity is an important indicator of healing progress, as gradual increases in movement often correlate with reduced pain, improved strength, and faster rehabilitation outcomes. However, monitoring a child’s activity during recovery can be challenging, especially once they leave the hospital setting.

Wearable devices provide a non-invasive and objective way to track post-surgical recovery, allowing clinicians to assess movement patterns, mobility restoration, and adherence to rehabilitation guidelines. Unlike self-reported movement logs, which may be unreliable due to pain, fatigue, or caregiver bias, wearables offer continuous data on activity levels, sedentary behavior, and physiological responses.

This article explores how wearable devices can support pediatric post-surgical recovery, focusing on key considerations, device selection, and best practices for monitoring movement during rehabilitation.

2. Key Considerations for Post-Surgical Activity Monitoring

Each child’s recovery process varies based on the type of surgery, level of post-operative pain, and mobility restrictions. Standard movement tracking methods, such as step counts or movement intensity classifications, may not fully capture functional recovery in children with post-surgical limitations.

• Differences in recovery needs based on surgery type:
  • Orthopedic surgeries (e.g., fracture repair, spinal fusion) require gradual reintroduction of weight-bearing activities and careful tracking of asymmetrical movement patterns.
  • Cardiac surgeries (e.g., congenital heart defect repair) focus on monitoring exertion levels and ensuring children do not overexert themselves too soon.
  • Abdominal surgeries (e.g., appendectomy, gastrointestinal procedures) may require restrictions on certain movements, such as twisting, bending, or lifting.
• Pain management and movement limitations affecting activity monitoring:
  • Pain and discomfort may cause temporary reductions in movement, making it necessary to distinguish between voluntary rest and movement avoidance due to pain.
  • Children may experience uneven mobility patterns, such as favoring one side of the body after surgery, requiring customized movement tracking adjustments.
• Hospital vs. home-based recovery settings:
  • Inpatient monitoring allows for continuous tracking with direct clinician supervision, making it easier to correlate movement data with clinical milestones.
  • Home-based recovery relies on caregiver engagement and self-reported adherence to activity guidelines, making automated wearable tracking particularly useful.

Understanding these factors ensures that post-surgical movement tracking aligns with medical recovery goals, rather than simply measuring overall activity levels.

3. Choosing the Right Wearable Devices for Post-Surgical Monitoring

Not all wearable devices are suited for post-surgical monitoring, as children recovering from surgery may have movement restrictions, sensory sensitivities, or medical dressings that affect wearability and adherence. Selecting the right device requires balancing accuracy, comfort, and feasibility for both short- and long-term recovery tracking.

Accelerometers and Motion Sensors

Accelerometers are widely used for tracking movement patterns, mobility levels, and sedentary time. They provide a non-intrusive way to measure activity without requiring active participation from the child.

• Best for: Assessing general movement trends, postural transitions, and adherence to prescribed activity levels.
• Limitations: May not accurately detect low-intensity movement or restricted mobility patterns in children recovering from orthopedic or abdominal surgery.

Heart Rate Monitors (ECG vs. PPG Sensors)

Heart rate tracking can provide valuable insights into physiological recovery, particularly in children recovering from cardiac or major surgical procedures.

• ECG-based chest monitors provide high-accuracy cardiac monitoring, useful for tracking exertion levels in children with cardiac restrictions.
• PPG-based wrist sensors offer a more convenient but slightly less accurate alternative, suitable for general exertion tracking.

Multi-Sensor Wearables

Some advanced wearables integrate motion tracking, heart rate variability, and sleep monitoring, offering a comprehensive picture of recovery progress.

• Useful for: Assessing energy expenditure, autonomic nervous system recovery, and sleep quality in children with longer recovery timelines.
• Ideal for: Children recovering from major surgeries where both mobility and physiological stress responses must be monitored.

Considerations for Device Selection

Post-surgical wearables must be comfortable, adaptable, and easy to use, ensuring children and caregivers can comply with tracking requirements.

• Soft, flexible materials prevent irritation, especially in children with surgical dressings or sensitive post-operative skin.
• Secure but adjustable attachment methods (e.g., clip-on sensors, soft straps) help prevent discomfort or interference with wound healing.
• Automated data collection with cloud syncing reduces caregiver burden, ensuring clinicians receive real-time recovery insights.

By selecting wearables that align with recovery needs, clinicians and researchers can track post-surgical progress more effectively, ensuring safe and optimal rehabilitation outcomes.

4. Best Practices for Data Collection in Post-Surgical Recovery

Tracking movement during post-surgical recovery requires careful planning to ensure reliable data collection without adding stress to the child or caregivers. Since children may experience pain, fatigue, or restricted mobility, researchers and clinicians must balance data accuracy with patient comfort and adherence.

Ensuring High Compliance by Reducing Burden

Children recovering from surgery may be less likely to wear a device consistently, especially if it feels uncomfortable or interferes with their rest. To maximize compliance, wearable devices should be easy to use, minimally intrusive, and require little effort from the patient or caregivers.

• Use lightweight, soft-material wearables to avoid irritation, especially for children with bandages, stitches, or healing wounds.
• Choose non-restrictive sensor placement, such as wrist or ankle, unless the area is affected by surgery.
• Provide clear, simple instructions for caregivers on device use, charging, and troubleshooting to minimize frustration.

Guiding Families on Device Use and Movement Tracking

Parents and caregivers play a crucial role in monitoring post-surgical activity levels. Providing structured guidance on how to track movement can help improve device adherence and data reliability.

• Explain the importance of tracking movement and how it relates to recovery progress.
• Set realistic expectations for activity, helping parents distinguish between expected rest periods and concerning inactivity.
• Encourage caregivers to log additional recovery details, such as pain levels, mood, and energy levels, to add context to the wearable data.

Managing Missing Data Due to Pain or Non-Wear Periods

Since children may remove wearables due to discomfort or fatigue, missing data can be a common issue in post-surgical monitoring. Implementing strategies to handle gaps in movement data helps ensure accurate recovery assessments.

• Use movement thresholds to differentiate between inactivity due to pain and natural resting periods.
• Allow flexibility in data collection schedules, ensuring children are not forced to wear devices when feeling unwell.
• Incorporate alternative movement tracking methods, such as caregiver-reported mobility logs, to supplement missing data.

By minimizing patient burden and engaging caregivers in the data collection process, researchers can obtain more complete and meaningful recovery data.

5. Interpreting Wearable Data for Recovery Assessment

Wearable data provides objective insights into post-surgical recovery, but interpreting it correctly requires an understanding of how mobility changes over time and what movement trends indicate healing progress or potential complications.

Identifying Movement Trends That Indicate Recovery

A gradual increase in daily movement levels and activity frequency is typically a positive sign of healing. Tracking these trends over days or weeks can help clinicians determine whether recovery is progressing as expected.

• A steady rise in daily movement minutes suggests improved mobility and reduced pain levels.
• More frequent posture changes and standing time indicate greater confidence in movement and muscle recovery.
• Resumption of normal activity patterns (e.g., walking to the kitchen, playing in short bursts) shows functional improvement.

Detecting Inactivity Periods That May Signal Complications

Prolonged inactivity or sudden reductions in movement may indicate pain, fatigue, or potential post-surgical complications. Wearable data can help identify red flags that may require medical attention.

• Sharp declines in movement from one day to the next may indicate pain flare-ups or new mobility restrictions.
• Long sedentary periods beyond expected rest time could suggest excessive fatigue or difficulty moving due to discomfort.
• Inconsistent activity patterns (e.g., bursts of movement followed by extended inactivity) may indicate overexertion or pain-related avoidance behaviors.

Correlating Movement Data with Clinical Milestones

Recovery is often assessed based on clinical guidelines, such as when a child should be able to stand unassisted, walk without support, or resume physical therapy activities. Wearable data can help validate whether these milestones are being met on time.

• Tracking step count increases in children recovering from orthopedic surgery ensures progressive weight-bearing activity.
• Heart rate variability trends can provide insights into autonomic nervous system recovery following major procedures.
• Comparing wearable data to pain or medication logs helps clinicians adjust post-operative care strategies.

By identifying movement trends, detecting inactivity risks, and correlating data with clinical milestones, wearable tracking can offer valuable, real-time recovery insights.

6. Using Wearable Data to Guide Rehabilitation and Activity Recommendations

Wearable data is not just for tracking recovery—it can also help shape rehabilitation programs and improve adherence to post-surgical activity guidelines. By using real-time movement data, clinicians can personalize activity recommendations to match each child’s recovery stage.

Creating Individualized Movement Goals

Every child’s recovery timeline is different, so movement goals should be adjusted based on progress rather than standardized benchmarks.

• For orthopedic recovery: Gradual step-count increases and mobility exercises should be aligned with joint stability and weight-bearing ability.
• For cardiac recovery: Movement goals should balance gradual activity reintroduction with heart rate monitoring to avoid overexertion.
• For abdominal recovery: Low-impact activities should focus on preventing muscle deconditioning without straining surgical sites.

Ensuring Safe Activity Progression

Real-time wearable tracking helps clinicians determine when a child is ready to increase activity levels while avoiding premature overexertion.

• Detecting stable movement trends over multiple days allows for safe rehabilitation progression.
• Using wearable alerts for excessive inactivity can prompt caregivers to encourage light movement when appropriate.
• Monitoring pain and fatigue in relation to activity levels ensures that movement is increased at a manageable pace.

Providing Feedback to Families and Clinicians

Wearable data can help families feel more engaged in the recovery process by offering clear, objective feedback on progress.

• Daily or weekly reports summarizing activity levels can show caregivers how their child is progressing compared to expected recovery timelines.
• Providing recommendations based on data trends can guide families on when to encourage more activity or allow more rest.
• Allowing clinicians to remotely access movement data enables faster adjustments to rehabilitation plans if recovery is progressing slower or faster than expected.

Monitoring Long-Term Recovery Patterns

For some surgical procedures, recovery extends beyond the initial weeks post-surgery. Continued activity tracking can help detect potential setbacks or long-term improvements.

• Tracking movement several months after surgery can identify whether full mobility has been restored.
• Long-term monitoring for children with complex surgeries ensures lasting recovery without complications.
• Identifying patterns of sedentary behavior post-recovery helps prevent long-term deconditioning.

By using wearable data to personalize rehabilitation programs, ensure safe activity progression, and provide valuable feedback to families, clinicians can improve post-surgical recovery outcomes in pediatric patients.

7. Conclusion and Recommendations

Using wearable devices to monitor post-surgical recovery in pediatric patients offers a valuable, objective way to track mobility restoration, pain-related movement changes, and adherence to rehabilitation protocols. Unlike traditional self-reports, wearable data provides real-time insights into movement trends, allowing clinicians to adjust recovery plans based on actual activity levels rather than assumptions.

Key takeaways include:

• Post-surgical movement monitoring should be adapted to the type of procedure. Orthopedic, cardiac, and abdominal surgeries have different mobility restrictions and recovery expectations that should guide device selection and movement goals.
• Wearable devices must be comfortable, non-intrusive, and easy to use. Soft materials, secure but flexible attachment options, and automated data syncing help ensure compliance during recovery.
• Tracking movement trends is more valuable than focusing on total activity levels. A steady increase in mobility, rather than a single daily step count target, is a more reliable indicator of recovery progress.
• Wearable data can help detect inactivity risks that may indicate pain or complications. If movement decreases unexpectedly, clinicians can intervene early to assess potential issues.
• Personalized movement goals and feedback improve engagement in recovery. Providing caregivers and clinicians with meaningful data reports helps ensure that activity recommendations are followed correctly.
• Long-term tracking may be beneficial for complex recoveries. Monitoring movement beyond the initial recovery phase can detect late-stage mobility issues and prevent deconditioning.

By integrating wearable data into post-surgical care, researchers and clinicians can gain a deeper understanding of pediatric recovery patterns, improve rehabilitation outcomes, and help children return to daily activities safely and efficiently.
