Biofeedback

A

•What is Biofeedback (BF)

–Sensory modality used to measure muscular activity through electrical signals that are detected through the skin.

  • Signals are produced by the unit in the form of visual and auditory outputs
  • What is it used for?

–Biofeedback is used to teach patients how to control involuntary muscular activity by controlling the displayed signals.

45
Q

sEMG for Spastic Muscle

A
46
Q

Biofeedback (sEMG) sensativity

A

–Sensitivity

•The ability to detect muscle electrical activity through the skin

•The higher the sensitivity, the more muscle activity you will detect

•The lower the sensitivity, the less muscle activity you will detect

–Example

•If I want to detect electrical activity in a quad muscle that is inhibited, should I increase or decrease the sensitivity? INCREASE

–Gain

  • Unit of measure on the biofeedback unit that determines the ability to detect muscle electrical activity through the skin
  • Inversely proportional to your sensitivity

–”As you increase the gain you are decreasing the sensitivity”

–Tester beware!!

•If your answer choice has, “Sensitivity (Gain) will be increased,

–base your decision on sensitivity and not gain.

Q

Dix-Hallpike

WHICH SIDE SHOULD BE TESTED FIRST?

A

Examine Involved side FIRST

Examines

•Anterior/Posterior SCC function

Procedure

  • Patient is long sitting with head rotated 45 degrees to suspected side
  • Patient is brought into supine with head extended 30 degrees while maintaining the 45 deg rotation

Interpretation

  • Presence of nystagmus and vertigo is indicative of posterior SCC dysfunction
  • Ear side down is the tested side

STEPS

Step 1: The patient is placed into long sitting on a table with head rotated 45 degrees to the suspected side

Step 2: The patient is moved from the long sitting position with head rotated 45 degrees, to supine with the head extended 30 degrees beyond horizontal with the head maintained at 45 degrees rotation.

Step 3: This position is held while the therapist looks for nystagmus and/or reports of vertigo.

96
Q

Head Impulse Test (Head Thrust)

A

LOOKING FOR UVH

  • What does it examine:
  • Horizontal SCC function
  • Procedure:
  • Patient head is flexed to 30 degrees
  • Head is rotated rapidly into an unpredictable direction
  • Interpretation:
  • UVH is present when head is rotated and eyes cannot remain on target

Positive for UVH – Problem is on the side that is being rotated to

STEPS

Step 1: Have the patient fixate on the clinician’s nose

Step 2: When testing the horizontal SCC, the head is flexed 30°. Patients are asked to keep their eyes focused on a target while their head is manually rotated in an unpredictable direction using a small-amplitude (5° to 15°), moderate-velocity (approximately 200°/sec) rotation.

Provides reliable insight when one side of the vestibular system has a complete loss of functioning.

  • Head is rotated rapidly to both sides
  • Interpretation

STEPS

Step 1: The patient is positioned supine with the head flexed 20°.

Step 2: Rapid rotations to the sides are done separately and the clinician observes for nystagmus and vertigo.

98
