Functional Electrical Stimulation (FES) Therapy: Applications, Techniques, and Evidence, Exams of Social Sciences

United States International UniversitySocial Sciences

This comprehensive study guide explores the applications of functional electrical stimulation (fes) in various therapeutic contexts, including gait assistance, shoulder subluxation, and grasp improvement. it details electrode placement, stimulation parameters, and clinical evidence supporting fes use in stroke, multiple sclerosis, and cerebral palsy rehabilitation. The guide also examines fes cycling and rowing, outlining protocols and potential benefits. key considerations for patient selection and medical issues are addressed, making it a valuable resource for healthcare professionals and students.

FES EXAM STUDY GUIDE
Functional Electrical Stimulation - Answers :e stim provided to muscles during a
functional activity
fes as a dorsiflexion assist during gait - Answers :-electrodes are typically placed on the
anterior tibialis and peroneal nerve
-triggered by a foot switch or external trigger
-considered an orthotic substitute
appropriate candidates - Answers :no significant ROM deficits, no significant knee or hip
problems preventing walking, no significant spasticity of the plantarflexors
pulse duration - Answers :200-400 msec
frequency - Answers :to obtain tetany
20-30 Hz
amplitude - Answers :create a 3- to 3+/5
on/off time - Answers :times with person's gait
ramp up/down - Answers :n/a
foot switch - Answers :defects a pressure decrease as person enters swing and triggers
dorsiflexion
other potential benefits - Answers :-increased strength if person has some volitional
movement already
-decrease in spasticity of plantarflexors
walkAid - Answers :-battery-operated, one channel stimulator
-uses tilt sensor to control stimulation
--eliminates need for external wires or a remote heel sensor
evidence, post stroke - Answers :-increased walking speed
-increased gait speed and other functional outcomes
-increased user satisfaction
MS evidence - Answers :-increased walking speed
-decreased physio cost
cerebral palsy evidence - Answers :no change in gait speed

FES EXAM STUDY GUIDE

Functional Electrical Stimulation - Answers :e stim provided to muscles during a functional activity fes as a dorsiflexion assist during gait - Answers :-electrodes are typically placed on the anterior tibialis and peroneal nerve

  • triggered by a foot switch or external trigger
  • considered an orthotic substitute appropriate candidates - Answers :no significant ROM deficits, no significant knee or hip problems preventing walking, no significant spasticity of the plantarflexors pulse duration - Answers :200-400 msec frequency - Answers :to obtain tetany 20 - 30 Hz amplitude - Answers :create a 3- to 3+/ on/off time - Answers :times with person's gait ramp up/down - Answers :n/a foot switch - Answers :defects a pressure decrease as person enters swing and triggers dorsiflexion other potential benefits - Answers :-increased strength if person has some volitional movement already
  • decrease in spasticity of plantarflexors walkAid - Answers :-battery-operated, one channel stimulator
  • uses tilt sensor to control stimulation --eliminates need for external wires or a remote heel sensor evidence, post stroke - Answers :-increased walking speed
  • increased gait speed and other functional outcomes
  • increased user satisfaction MS evidence - Answers :-increased walking speed
  • decreased physio cost cerebral palsy evidence - Answers :no change in gait speed

fes and increased foot clearance during ambulation - Answers :-pts response to device can be assessed using any portable stimulator that provide some type of trigger to time the FES to walking

  • two devices (walk aide and new L300) are currently on the US market specific for foot drop and each company can be contacted to trial a device with a patient
  • medicare has approved coverage for the walk aide and ness L300 for incomplete SCI. insurance coverage for other diagnoses varies and is dependent on the insurance comp
  • can have a large impact on walking function FES for shoulder subluxation - Answers :-used for pts with severe weakness or flaccidity in the muscles supporting the glenohumeral joint, leading to subluxation due to effects of gravity
  • most with strokes and implanted devices electrode placement for shoulder subluxation - Answers :-electrodes usually placed on posterior deltoid and supraspinatus
  • pt must be positioned to avoid gravity from counteracting the effect of stim pulse duration - Answers :200-400 m sec frequency - Answers :to obtain tetnacy amplitude - Answers :to achieve contraction and relocation of humerus into the glenoid fossa off/off ratio - Answers :start with 1:3 and work up to 12: treatment time - Answers :goal - 6 to 8 hours (implanted systems have used up to 23 hours) evidence for shoulder subluxation - Answers :-decrease pain with passive ER
  • decrease subluxation key points for FES to decrease shoulder subluxation - Answers :-effects are more likely to be seen with acute versus chronic stroke
  • most commonly stimulated muscles are posterior deltoid and supraspinatus
  • pain and subluxation may both decrease; decreases in pain may be long lasting
  • it may allow faster improvements post stroke
  • stim parameters should be set to minimize fatigue (low freq and amplitude) since goal is longer treatment time fes for grasp - Answers :-extensor digitorum, the extensor policis brevis, flexor digitorum superficialis, flexor pollicis longus, and the thenar muscles
  • wrist held in 10 to 20 degrees of extension
  • any unit with a trigger

potential benefits of cycling as pre locomotor training for individuals with some volitional lower extremity movement - Answers :-decreased balance deficits

  • can focus on movement pattern
  • can be done at home SCI, medical issues to consider before implementing fes cycling - Answers :-history of spontaneous fx
  • history of autonomic dysreflexia
  • sensation
  • orthopedic concerns
  • respiratory demands
  • spasticity
  • pressure sores
  • pre existing medical issues cerebral palsy medical issues to consider - Answers :-orthopedic issues
  • history of seizures
  • implanted devices
  • cognitive status stroke and medical issues to consider - Answers :-medical clearance to begin exercise
  • cognitive status
  • pre existing medical issues
  • tone / spasticity standard muscles to stimulate during cycling - Answers :glut max quad hamstrings cycling time - Answers :30 to 60 mintes per session at 50 rpm for 60 minutes = 3000 reps key points with few cycling - Answers :-set initial stim levels lower for pts with remaining sensation
  • encourage volitional movement if present as long as it doesnt interfere
  • typical muscles are quads, hamstrings, gluts but others may be possible depending on pt needs and the cycle being used
  • cycling for 30 to 60 minutes, 3 times per week is supported by the literature for pts with SCI. cycling 5 times a week is reported but may be overly fatigue
  • typical cycling cadence is 40 - 50 rpm with resistance increasing as able fes rowing - Answers :-increase in oxygen uptake and distance rowed --fes rowing sessions, 30 minutes, 3 times per week for 12 weeks
