1 Neuromuscular Electrical Stimulation: A Review of the Literature By: Jessica Stewart B.A. Wayne State University Graduate Student

2 Neuromuscular electrical stimulation (NMES) has been used for many decades a part of rehabilitative therapy In the early 2000’s, the Food & Drug Administration approved NMES for use with dysphagia treatment

3 Uses O NMES applies electrical impulses to the nervous system to stimulate sensory and/or motor neurons O Common Uses Relaxation of muscle spasms Prevention or retardation of disuse atrophy Improvement of local blood circulation Re-education of the muscle

4 Application Transcutaneous O Stimulates sensory nerves under the skins surface O Benefits Non invasive Generally inexpensive O Cons Needs higher amplitude to reach deeper muscles

5 Application O Percutaneous Electrodes temporarily placed in muscle O Surgical Permanent Placement

6 Candidates O Ideal Individuals who have central nervous system abnormalities with intact peripheral nerve functions O Contraindications Individuals with motor neuron death Individuals with progressive fatigue Individuals with pacemaker, metal implant, skin breakdown, cancer, cardiac or seizure disorder, impaired peripheral nerves, pregnant

7 Swallowing Therapy O Speech Language Pathologists typically administer transcutaneous applications O One to Two sets of electrodes placed on anterior neck O NMES is most effective if paired with the actual swallowing of a bolus

8 Studies Permsirivanich et al. (2009) O Participants: stroke survivors with dysphagia O Group 1: NMES O Group 2: Traditional Postural adjustment Supraglottic swallowing Mendelsohn maneuver Effortful swallow O Results: NMES greater increase in functional oral intake

9 Studies Christiaanse et al. (2011) O Participants: pediatric patients with dysphagia O Group 1: NMES O Group 2: Traditional therapy Oral motor training Diet modification O Results: MNES did lead to improvement but not more than traditional therapy

10 Studies Heijnen, Speyer, Baijens, and Bogaardt (2011) O Participants: Parkinson's patients with oropharyngeal dysphagia O Group 1: Traditional Therapy Oral motor exercises, airway protection maneuvers, posture adjustments O Group 2: Traditional Therapy listed above and MNES to suprahyoid musculature at motor level O Group 3:Traditional Therapy listed above and MNES to suprahyoid musculature at sensory level O Results: all the groups demonstrated a significant increase in health related qualities of life, however there was no difference between the groups

11 Studies Bulow, Speyer, Baijens, Woisard, and Ekberg (2008) O Participants: 25 individuals who received swallowing therapy from three area hospitals O Group 1: NMES O Group 2: Traditional Therapy Diet modification Oral motor exercise Varying postures and maneuvers O Results: Both groups demonstrated significantly positive results; however, there was not a statically significant difference between groups

12 Studies Carnaby-Mann and Crary (2007) O Meta Analysis of 7 transcutaneous neuromuscular electrical stimulation studies O Results: Significant, but small, results support use of NMES to improve swallowing and therapeutic effects maintain present even after the stimulation has been removed

13 Biggest Challenge O Lack of standardized and objective outcome measurement All results are based on clinician’s subjective judgment

14 Should I Do It? O Review current literature O Safety of patient O Cost O Client’s needs and values
