- - This is the third Electrotherapy lecture in the Electrotherapy II course targeting second year students, spring semester in the Faculty of Physical Therapy, Benha University, Egypt.
In this lecture, we discuss the following items in the Principles of Electrical Stimulation: -
1. Physiologic response to electrical stimulation
2. Physiological and therapeutic effects of electrical stimulation
3. Contraindications and precautions of electrical stimulation
4. Clinical application steps
Good Luck
لو ينفع يدكتور تنزليلنا الداتا اللي بتشرحي منها
ربنا يبارك لحضرتك يا دكتورة
ممتنين لوجود محاضراتك فى حياتنا 🤍⚘
ربنا يكرمك حسام .. بالتوفيق دايما
2. Complete the following sentence:
Electrodes should not be placed directly over bony prominences because ……………………………………
Will make discomfort and burn
Of greater resistance of bone and poor adhesion of electrodes
because the greater resistance
of bone and the poor adhesion of electrodes to highly contours surface increase the risk discomfort
and burns.
High resistance of bone cause High heat and burn
The greater resistance of bone and poor adhesion of electrodes
Because of the greater resistance of bone and will decrease stimulation and current density
1. Complete the following sentence:
In Electrically evoked muscle contraction, ……………………. muscle fibers are stimulated and the motor units fire in ……………. pattern
Large diameter fast twitch
Synchronous
Large type 2 fast twitch
Synchronous
Large dimeter type 2 fast twitch muscle fiber
Synchronous pattern
عبدالله محمد فتحي ابوالمعاطي
Type 2 fast twitch.... synchronous
Fast twitch ms fibers.
Synchronous.
Type2 large diameter fast twitch muscle fibers
Fire synchronous
2. Complete the following sentence:
In muscle stimulation, Functional motor points are characterized by ………………
nerve enter muscla at this point most conductive area with least resistance
سعيد مجدي السعيد
Enter of nerVe to the muscle
Area With best motor response
nerve enter the muscle at these point
less resistance to current
ساره عصام فاروق
Less resistance to the current
.best motor response
.less current amplitude
Higher conductivity than other points , least resistance, best motor response with less current amplitude

Nice presentation keep going thanks for your hard work i appreciate.
2. Complete the following:
To stimulate quadriceps contraction, the patient positioned in semi-reclined with a bolster under the knee because to …………………………………
Because in this position the quadriceps is mildly stretched and more likely to achieve a visible limb movement (about 20 degree of knee flexion)
أحمد محمد إبراهيم
Achieve a visible limb movement
Be Slight length
To Achieve visible limb movement
اياد شريف صلاح رياض
To achieve visable limb movement

1. Enumerate stimulation points in electrical stimulation
Over trigger point
around the painful area
Over specific dermatome myotome and sclerotome Acupuncture point
Trigger points ( vertical , horizontal )
Over peripheral nerve
Point of motor functional
On or around pain area
أماني الدسوقي
over trigger point
around the painful area
over specific dermatoma
aquapuncture point
عمرو السيد خاطر
Over trigger point
Acupuncture point
Over peripheral point
Around the painful area
Over specific dermatome myotome and sclerotome acupuncture
Trigger point (vertical,horisontal)
1. Complete the following sentence:
The hot spots noted under electrodes following stimulation are due to ……………………..
increase current density lead to thermal and elcetro chemical
سعيد مجدي السعيد
due to the thermal and chemical effects of the current
And because of increasing in current density within the electrode area
أية صلاح ابراهيم
Increasing in current density
increase current denisty
ساره عصام فاروق
due to the Thermal or electrochemical effects
And because of increase in current density within the electrode area
