- Brief Summary
The investigators seek to evaluate the effectiveness of Armeo®Spring Pediatric training, as compared to conventional treatment, in improving upper extremity function in children with Narakas I brachial plexus injury, aged 5-8 years, using the Mallet modified scale and passive range of movement, immediately post intervention and at 3 and 6 months´ follow up. The investigators will also monitor the appearance of adverse effects during and post intervention, with a follow up at 3 and 6 months.
- Detailed Description
Obstetric brachial plexus injury is caused by damage of the cervical nerve roots C5-T1 during delivery. It has traditionally been treated with occupational and physical therapy during the first few months, evaluating at 1, 3 and 6 months if primary surgery is required. The goal of primary surgery is to repair the damaged nerve roots and restore neural function. Despite surgery, a large percentage of children will remain with varying degrees of paralysis. Since Narakas I ("Erb's") paralysis is the most common, motor sequelae usually involve limited shoulder abduction, restricted shoulder external rotation and elbow flexion contracture. This sequelae requires ongoing physical and occupational therapy, especially during school age, to ensure adequate upper extremity function and participation.
Armeo Spring Pediatric is a robotic tool that enables upper extremity training using virtual reality. Virtual reality is usually well tolerated and highly motivating to school age children. Since it's a relatively new tool, its effectiveness in the treatment of obstetric brachial plexus injury has not been documented.
This study aims to evaluate the effectiveness of Armeo Spring Pediatric training as compared to conventional therapy (occupational and physical therapy), in improving the upper extremity function of children with Narakas I (C5-C6) obstetric brachial plexus injury.
It will study two parallel groups of children ages 5-8. Both groups will receive 45 minute sessions, 3 times a week, for a total of 5 weeks (15 sessions). One group will train upper extremity function using Armeo Spring Pediatric and the other group will receive occupational and physical therapy, as detailed in protocol. They will be reevaluated at 3 and 6 months.
The appearance of adverse events, such as pain, fatigue or muscle contracture, will be documented during intervention, post intervention, and at 3 and 6 months. In the presence of one such adverse event, the training session will be suspended and the patient evaluated by physiatrist or orthopedic surgeon, with treatment if necessary. If the symptoms resolve before the next session, the patient will complete training as planned. If the symptoms are not resolved by the next session, the patient will be removed from the clinical trial until recovery.

- Primary Outcome Measures
Name Time Method Change in Modified Mallet Scale 0 weeks, 5 weeks, 17 weeks, 29 weeks It measures arm function in 7 different positions: arm at rest, shoulder external rotation, shoulder abduction, hand to neck, hand to mouth, hand to back and supination. Each position can be given a subscore from 1 (very altered) to 5 (almost normal), with a total score of 35. A higher score means better function (closer to normal movement or position).
In this case, the investigators will evaluate change in Modified Mallet Scale between baseline (0 weeks), post treatment (5 weeks) and follow up (17 and 29 weeks). It will take into account changes in total scores and subscores in different positions.
- Secondary Outcome Measures
Name Time Method Adverse events: pain. 5 weeks, 17 weeks and 29 weeks Will be measured by Visual Analogue Scale. The visual analogue scale is a unidimensional measure of pain intensity. The patient marks on the line the point that they feel represents their perception of their current state. The investigator will then measure in millimeters the distance from left to right (0-100 mm) to quantify the amount of pain. A low score means less intense pain and a high score means more severe pain.
The Visual Analogue Scale uses many formats (straight line, boxes, happy/sad faces). Because of the age of the study population in this clinical trial, the investigators have decided to use the happy/sad faces scale.
At 5, 17 and 29 weeks, the patient will be asked to document the pain they feel at that moment, not during the treatment.Upper extremity passive range of movement 0 weeks, 5 weeks, 17 weeks and 29 weeks Will be measured by goniometry
Adverse events: fatigue 5 weeks, 17 weeks and 29 weeks Will be measured by Borg Scale The Borg Scale is an instrument that quantifies the exertion perceived by the patient with a score from 0-10, as follows: 0 = at rest; 1 = very easy, 2 = somewhat easy, 3 = moderate; 4 = somewhat hard, 5-6 = hard; 7-8 = really, really hard; 8-9 = really, really, really hard; 10 = maximal effort.
At 5 weeks, the patient will be asked to document the fatigue they felt during the treatment.
At 17 and 29 weeks, they will be asked to document the fatigue they feel at that moment.Adverse events: muscle contracture 5 weeks, 17 weeks and 29 weeks Will only be recorded if present/absent, since there is no scale to measure it
