Week 6 E-Stim (NMES, FES, & EMS) Flashcards
NMES Definition
- Neuromuscular Electrical Stimulation
- Activation of skeletal muscle for strengthening, reeducation or edema reduction - Peripheral nerve depolarization to create a muscle contraction
Which depolarizes first Nerves or muscle cells?
Nerves have a lower threshold for depolarization and will depolarize before muscle cells
FES Definition
- Functional Electrical Stimulation
- Activation of skeletal muscle for reeducation or movement training for functional use
- May be used on innervated or denervated muscle
EMS Definition
- Electrical Muscle Stimulation
- Implications stimulation of denervated muscle- muscle cells depolarize to create a muscle contraction
What is the primary difference between NMES and EMS
The type of tissue stimulated in the main difference
True/ False NMES will not work for LMN
True
NMES will not work for LMN you will need to consider EMS
–> NMES and FES are options for UMN
what are the goals of NMES
- Strength and re-education
1. Prevent or treat muscular atrophy following disuse, immobilization or detraining
2. increase or maintain ROM
3. Re-education, retain or facilitate muscle for movement posture
NMES can Increase (blank) very rapidly
- Can increase motor recruitment rapidly
- Increasing number off motor units recruited
- Increasing frequency motor units recruited
- Motor units recruited more synchronously
NMES Evidence supports….
- Supports strengthening weakened muscles
- increased muscle size
- Improved motor unit recruitment
- Similar strength improvements compared to exercise
- Shown to prevent muscle atrophy***
True/ False the training intensities of ES and exercise have to be similar training intensities for strength gains
True
ES results show in early rehab…
- ES results in greater gains in strength than voluntary exercise or no exercise in early rehab when voluntary exercise may be difficult
- Significant positive relationship between strength of ES and strength gained
–> Post rehabilitation stages show little to no difference between subjects who use ES and those who do not
NMES for Strengthening and for Orthopedic conditions they are beneficial for early phases of rehab and…..
- Post knee surgery
- ACL reconstruction
- TKA
- Knee meniscal repairs
Non- Surgical benefits - Knee OA
-Patellofemoral Syndrome
BENEFICAL FOR ATROPHY ASSOCIATED RA
NMES can help with which kinds of critically ill patients
- COPD
-Chronic Heart Failure - Thoracic cancer
- After cardiothoracic surgery
Multiple studies show promise with NMES used for these critical conditions
NMES best evidence supports which kinds of patients?
Stroke
What is the goal of NMES for increasing ROM in neurological conditions?
Longer treatment time (low load, prolonged application)
