Daily Physical Activity in Myelomeningocele

Study Overview
=================
Brief Summary
-----------------
Obesity is getting more common and challenging to treat in children and adolescents with myelomeningocele. Therefore, it is becoming more important to determine daily physical activity in these patients. Daily walking performance and average steps per day in patients with low lumbar and sacral level myelomeningocele are shown to not differ from healthy controls. Step counts can not reflect all torsional accelerations associated with daily living activities. Omnidirectional accelerometers provide all types of body movement outputs and give detailed parameters of physical activity level and energy expenditure. There is no data about energy expenditure and physical activity level of the patients with myelomeningocele in daily routine. This study aims to quantify energy expenditure and physical activity of children and adolescents with low lumbar and sacral level myelomeningocele.

Detailed Description
-----------------
Children and adolescents with low lumbar and sacral level myelomeningocele, and age-, sex-, and BMI-matched controls were included. Omnidirectional accelerometer monitor (Actical®) was used to assess activity energy expenditure and daily durations spent in sedentary, light activity and moderate to vigorous physical activity (MVPA).

Arms and Interventions

| --- | --- |
| Patients with myelomeningocele<br>Patients diagnosed myelomeningocele with the neurological level between L5 and S3 | Device: Omnidirectional accelerometer monitor (3x3 cm and 16 g, Actical®, Philips Respironics)<br>* All participants were instructed to wear monitors for five consecutive days except during water-based activities. Data for each participant was collected to ensure included three valid weekdays. Daily activity energy expenditure (kcal/kg/min), and sedentary, light, moderate and vigorous levels (min) were examined using a software program.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average Activity energy expenditure (AEE) | Activity energy expenditure (AEE) (kcal/kg/min) refers to thermogenesis from all activities associated with daily living. An average amount of three valid weekdays will be calculated. | After wearing monitors for five consecutive days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average physical activity durations | The sedentary level (min) is the total amount of time when AEE below 0.01 kcal/kg/min. The light level is the total amount of time when AEE between 0.01 and 0.04 kcal/kg/min. The moderate level is the total amount of time when AEE between 0.04 and 0.10 kcal/kg/min. The vigorous level (min) is the total amount of time when AEE above 0.10 kcal/kg/min. | After wearing monitors for five consecutive days |
