Estim Muscle Contraction Flashcards
What is neuromuscular electrical stimulation
Use of electrical currents to produce muscle contractions in innervated muscle
What is the overload principles
Muscles adapt when they are forced to contract against a load that demands a strong contraction
What is the clinical principles for NMES
The intensity of the current needs to be high and the muscle needs to become fatigued. Recommended that the force 50% max voluttary isometric contraction (MVIC)
What percentage of the patients max voluntary isometric contraction (MVIC) to produce strength on a healthy muscle
50%
What percentage of the patients max voluntary isometric contraction (MVIC) to produce strength on an injured muscle
10%
Clinical applications for orthopedic conditions to use for NMES
Total knee replacement
ACL repairs
Prevent atrophy in patients with cardio respiratory disease
What is functional e-stim
Performance of functional activities by stimulating contractions at the time during an activity when the muscle should contract
What can you use functional Estim/muscle reeducation
Ambulation
Hand grasp
Aerobic and cardiovascular conditioning
Bowel and bladder function
What is the clinical applications for FES
Not to be painful
Able to be control and repeated
Must produce a contraction of sufficient force to carry out the desired activity
Clinical applications for spinal cord and cardiorespiratory function for FES
Electrically stimulated cycling increased bone mineral density (BMD)
Increase strength and endurance increase cardiovascular effects
What is the clinical application for stroke for FES
6 week period
Home based sensory and motor level electrical stimulation program improved arm function, voluntary movement and muscle tone in patients after stroke
Similar to people with SCI
Clinical application for neurological diagnosis (TBI, MS, CP) for NMES (pulsed biphasic/russian)
Improvement UE function
Dynamic bracing in children with CP are found to decrease spasticity
Increase grip strength
Improve posture
Gait
