Clinical Trial Summary

The goal of this study is to obtain data that well help inform the feasibility and design of a randomized control trial of the therapeutic Neuromuscular Electrical Stimulation (NMES) technique in improving the swallowing function of young infants presenting with severe dysphagia.


Description:

Infants with severe neurologic disability often have difficulty in eating by mouth due to a disruption in the swallowing process. This swallowing dysfunction, also known as dysphagia, is often evident early in life and when severe can be permanent. Dysphagia can lead to an inability to take in enough food to maintain an adequate weight and result in malnutrition. It also can result in food going into the lungs instead of the stomach, resulting in an illness called aspiration pneumonia. Both of these complications may require feeding by tube either through the nose into the stomach or directly into the stomach via the abdominal wall, to bypass the swallowing process. This process is resource intense, can be associated with a number of complications and may result in a reduced quality of life for both the infant and caregivers. Currently, there are no effective treatments to change the natural course of dysphagia in this context.


Recruitment information / eligibility

Status Completed
Enrollment 10
Est. completion date July 2012
Est. primary completion date July 2012
Accepts healthy volunteers No
Gender Both
Age group N/A to 12 Months
Eligibility Inclusion Criteria:

- Infants with severe dysphagia on VFFS as defined by dysphagia resulting in aspiration with swallow of at least 2 food textures (e.g. thin and thick liquid).

- We will include children with dysphagia due to a central neurologic deficit. The neurologic diagnosis will be based on the diagnosis from the treating physician.

Exclusion Criteria:

- Infants with a known or suspected neurodegenerative or peripheral neuromuscular condition or a medical condition that is a contraindication for NMES treatment (tumours in the neck region and neck soft tissue infections).

- Children with neurodegenerative disorders have been excluded as their natural history of dysphagia would be different from those with a static neurologic disorder.

Intervention

Device:
Neuromuscular electrical stimulation (NMES)
The intervention will consist of a period of treatment with NMES. This treatment will involve 20-45 minute feeding therapy sessions during which NMES will be administered by an Occupational Therapist. Frequency of therapy sessions will be 4 times per week for the first 2 weeks (as in inpatient, if hospitalized) and then biweekly for 14 weeks for a total of 36 sessions (over 16 weeks). For patients who are discharged prior to the first 2 weeks of treatment, outpatient sessions will be biweekly.

Outcome

Type Measure Description Time frame Safety issue
Primary Effectiveness The primary outcome will be an improvement in swallowing function as determined by videofluoroscopic feeding study from baseline to end of treatment (4 months after baseline). The swallowing function will be graded as to the number of textures the infant can safely swallow at three measurement points (baseline, 2 months and 4 months). An improvement in the number of textures the infant can swallow will define improvement. This will be recorded using a standard reporting form. 4 months No
Secondary Resolution of dysphagia The proportion of children whose dysphagia resolves (i.e. safe to feed on all consistencies of solids and liquids) at 4 months will be calculated. 4 months No
Secondary Feeding ability The feeding ability will be assessed using a clinical exam by an occupational therapist. baseline, 2 months and 4 months from enrollment No
Secondary Oral feeding ability and need for tube feeding Oral feeding ability and the need for tube feeding will be assessed using a structured scale based on parental report of dietary intake that includes: Level 1: Nothing by mouth, all nutrition by tube feeds, Level 2: <50% intake by mouth, tube feeding requirement, Level 3: >50% intake by mouth, tube feeding, requirement, Level 4: All by mouth, no tube feeding. baseline, 2 months, 4 months from enrollment No
Secondary Hospitalizations for lower respiratory tract illness The frequency of hospitalizations for lower respiratory tract illnesses in the 4 months following enrollment into the study will be determined by administering a structured questionnaire to parents. 4 months No
Secondary Safety and Adverse events Data collection of adverse events will occur through administration of a structured questionnaire by the occupational therapist at the end of each treatment session and just prior to the subsequent session. duration of subjects involvment in the study No
Secondary Caregiver acceptability and perception of feeding Two questions using a 10 cm visual analogue scale will ask whether parents were satisfied with the treatment process and whether the caregiver felt that their child's feeding ability improved during treatment. Two further open ended questions will probe what aspects of the treatment they felt were positive and what aspects they felt were negative. at 4 months No
Secondary Data on treatment procedures Data will be collected by the occupational therapist after each treatment session. This will include method of feeding, amount of food taken, response to treatment, length of treatment session, location of electrode placement and amplitude of stimulation used. 4 months No
