VitalStim® vs. AmpCare ESP™: Which Electrical Stimulation is Best for Pediatric Feeding and Swallowing Therapy?
For children with feeding and swallowing difficulties, electrical stimulation can support muscle strengthening and function. Two of the most recognized electrical stimulation systems in therapy are VitalStim® and AmpCare ESP™. While both use neuromuscular electrical stimulation (NMES) to improve swallowing, there are key differences between the two—and growing evidence suggests that AmpCare ESP™ may offer significant advantages for pediatric populations.
In this post, we’ll compare these systems and explain why AmpCare ESP™ is emerging as the preferred option for children with dysphagia.
What is Electrical Stimulation for Swallowing Therapy?
Neuromuscular electrical stimulation (NMES) uses electrodes placed on the skin to deliver small electrical impulses to specific muscles, causing them to contract. This strengthens weak muscles and helps retrain motor patterns necessary for swallowing.
When combined with targeted therapy exercises, NMES can support better rehabilitation outcomes. However, different systems deliver NMES in different ways, affecting their overall effectiveness.
VitalStim® Overview
VitalStim® is one of the most widely recognized NMES systems for swallowing therapy and has been FDA-approved since 2001 for treating dysphagia in adults and children.
Key Features of VitalStim®:
Delivers electrical stimulation to the anterior neck to target muscles involved in swallowing.
Requires special certification for safe use.
Primarily used to strengthen muscles and improve swallowing coordination.
Limitations of VitalStim® for Pediatric Use:
Generalized Electrode Placement: VitalStim® primarily targets large anterior neck muscles. For smaller children, this can be less effective and more uncomfortable.
Fixed Frequency: VitalStim® has a single waveform setting, which may not be ideal for addressing varying muscle tone, strength, or fatigue levels in pediatric clients.
AmpCare ESP™ Overview
AmpCare ESP™ (Effective Swallowing Protocol) is a newer NMES system designed to provide more targeted and adaptive electrical stimulation to support both pediatric and adult populations.
Key Features of AmpCare ESP™:
Utilizes adjustable waveforms and intensities to ensure the stimulation matches the child’s needs.
Electrodes are placed submentally (under the chin) and along the jawline, avoiding the anterior neck to prevent discomfort and overactivation of muscles.
Combines NMES with task-specific swallowing exercises to promote more effective muscle coordination.
VitalStim® vs. AmpCare ESP™: A Side-by-Side Comparison
Feature VitalStim® AmpCare ESP™ Electrode Placement Anterior neck and jaw area Submental region (chin/jaw) Adjustable Intensity No (fixed frequency) Yes (adjustable waveform) Comfort May cause discomfort for children More comfortable due to jawline placement Postural Support Not included Includes posture-stabilizing support Target Population Primarily adults; also used with children Specifically designed for pediatric and adult use Muscle Activation Generalized muscle contraction Targeted activation for improved motor control
Why AmpCare ESP™ is More Effective for Children
1. Improved Comfort and Tolerance for Children
VitalStim® places electrodes directly on the throat, which can feel invasive and uncomfortable for many children. AmpCare ESP™'s submental placement under the chin and along the jawline is less intimidating and more tolerable for children, encouraging greater participation during therapy sessions.
2. Customization for Precise Muscle Activation
AmpCare ESP™ offers adjustable waveforms, allowing therapists to tailor the stimulation to each child’s needs. This prevents overstimulation, which can lead to fatigue, and ensures the targeted activation of muscles crucial for swallowing.
3. Postural Support for Better Swallowing
AmpCare ESP™ includes a supportive garment to stabilize the head and neck, promoting optimal posture during therapy. Since postural control is essential for safe swallowing, this feature significantly differentiates children with low tone, poor head control, or neurological conditions.
4. Evidence of Pediatric Success
Many speech-language pathologists report faster progress in pediatric clients when using AmpCare ESP™ due to its focus on task-specific exercises, comfort, and adjustability. Clinical case studies and anecdotal reports have shown improved swallowing function, especially in children with complex neurological conditions such as cerebral palsy and brain injuries.
Conclusion: A Child-Friendly Approach to Swallowing Therapy
While both VitalStim® and AmpCare ESP™ can support swallowing rehabilitation, AmpCare ESP™ stands out as a more effective and adaptable tool for children. Its more comfortable electrode placement, adjustable settings, and emphasis on postural alignment provide a safer, more effective experience for pediatric clients.
If your child’s speech-language pathologist recommends NMES as part of their feeding or swallowing therapy, ask about AmpCare ESP™. A thoughtful, child-centered approach can make all the difference in helping your child improve their swallowing skills and overall quality of life.
