Electrotherapy II: Principles of Electrical Stimulation, Part 2 (L2)

- This is the second 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. The characteristics describing the single pulse:
(A) Peak amplitude
(B) Peak-to-peak amplitude
(C) Rise time
(D) Decay time
(E) Intrapulse interval
(F) Phase duration
(G) Pulse duration
(H) Phase charge
2. Strength duration curve
3. Duty Cycle
4. Ramp time
5. Total current
6. Modulation
7. Current density
Good Luck

The duration needed by two rheobase to elicits minimal detectable motor response

[@mariumelhet4061]

is the duration of a stimulus two times the rheobase strength capable of
eliciting a minimally detectable motor response.
