direct current galvanic Flashcards
electrostimulation of galvanic currents include
low frequncey current
high frequncy ,,
intermeditate frequency current
under low frequncy currents we have
galvanic tens faradic sinosudial didanamic
what low current was used in 1888
sinosudial
electrical curents with zero frequncy flowing in the same direction is called what
direct current
what type of current is a direct current
monophasic current
chemical effects of direct current
iontophoresis
meducal galvansim
surgical galvanisim
interpolar and polar falls under what effect of DC
PHYSIOLOGICAL
INTENDED USES FOR CHEMICAL EFFECTS
TO LOCALIZE THE CHEMICAL SUBSTANCE TO THE DESIRED PLACE OFTHE BODY
ADMINISTRING UNWANTED SUBSTANCE THROUGH THE SKIN
to increase the effect
of that substance by storing substances
that are absorbed very slowly.
PHYSIOLOGICAL EFFECT
• Current pushes ions through the
electrode from the skin layers to
the treated area.
IN IONTOPHORESIS WHAT KINDA DEVICE IS USED
THE ONE THAT GIVE S A CONSTANT GALVANIC CURRENT
THE MAXIMUM CURRENT INTENSITY IS 5MA
TREATMENT TIME FOR IONTHOPHORESIS IS
15…30 MIN
DOSE ADJUSTMENT IS RELATED TO WHAT
TOTAL TREATMENT TIME
CURRENT INTENSITY
IONIC DRUG SOLUTION
CHEMICAL STRUCTURE
CLINICAL DOSE RANGE FROM
0…80
NEGATIVE ION DELIVERED FROM THE POLE
IODINE CHLORINE SALICYLATE CITRATE ACETATE
POSITIVE ION DELIVERED FROM THE POLE
ZINC COPPER MAGNESIUM HISTAMINE HYDROCORTISONE
BIPOLAR IONTHOPHORESIS IN WATER IS USED FOR
ACUTE CONDITIONS FOR TREATMENT
CONTRADICTIONS FOR IONTHOPHORESIS
accute sensitivity or allergy to therapuetic ions
over damaged skin or open lesions
sensory defect
finding an implant in the application area
what is not used if theres an allergy to sea food
iodine
if there is an ulcer and gastritis what ion causes a reaction
hydrocortisone
what ion is not used if there is a allergy to aspirin
salicylate
if there is a metal sensitive patient what ion should be avoided
copper zinc magnesium
medical galvanisim is divided into
anodal , cathodal and anode-cathode opposed galvanisim
ANODAL GALVANISIM
USED IN SUBACUTE PAIN
ELECTRODE POSITIVE
USED IN JOINT SPRAINS AND STRAINS AND RHEUMATIC DISEASES
AND THE APPLICATION TIME IS 40-50 M
CATHODAL GALVANISIM
USED IN CHRONIC PAIN CONDITIONS \
USED FOR 20-30M
USED IN EXTRA ARTICULAR RHEUMATIC ARTHRITIS
SURGICAL GALVANISIM
USED FOR THE REMOVAL OF HAIR AND DESTRUCTION OF THE BLISTERS AND UNWANTED TISSUE WITH STRAIHJT CURENT
ANELECTROTONUS AND CATELECTROTONUS ARE UNDER
POLAR EFFECTS
IN THE INTERPOLAR EFFECT WHAT SUBSTANCE IS RELAESED
HISTAMINE AND VASODILATION OCCURS
TIME RANGE FOR STIMULATING THE NERVES AND MUSCLES INTERMITTENTLY IS WHAT RESPECTIVELY
20
100
THE MOST MODIFIED FORM OF GALVANIC CURRENT IS
INTERMITTENT GALVANIC CURRENT
SURGE GALVANIC
HAS 25 CONTRACTION PER MINUTE
STIMULATES THE MOTOR NERVES AND MUSCLE CONTRACTION
WHAT IS A TETANIC CONTRACTION
WHEN A STEADY MUSCLE IS SEEN OVER 60 C0NTRACTIOS PER MINUTE
DENERVING DOES WHAT
STIMULATES THE MUSCLES
PHYSIOLOGICAL EFFECTS OF MODIFIED GALVANIC CURRENT
ON SENSORY NERVES
ON MOTOR NERVES
ON DENERVTED NERVES
POLE EFFECTS
MODIFIED STRAIGHT CURRENT ARE USED IN
TREATMENT OF DENERVATED MUSCLES
CHANGES SEEN IN DENERVATED MUSCLES
MUSCLE LOSSES ITS IRRITABILITY
LOSSES ITS CONTRACTABILITY
LOSSES ITS ELASTICITY
MONOPOLAR TECHNIQUE
USES THE 1PEN AND 1PLATE ELECTRODE
USE 90 CONTRACTIONS FOR 1 MINUTE
USED IN OPPENENS POLLICIES MUSCLE AS A RESULT OF MEDIAN NERVE INJURY
BIPOLAR TECHINQUE UNDER IONTHOPHORESIS IS WATER
USES TWO PENS FOR DEEP MUSCLE
FOR THE TWO PLATE ELECTRODE….USE 7.3.10 CONTRACTIONS FOR 20 MIN
PLACE THE PLATES ON THE ORIGIO AND INSERTIO
INDICATIONS FOR GALVANIC
USED FOR DENERVATED MUSCLES
TO INCEASE MSUCLE TONE
USED FOR CIRCULATORY DISORDERS
