1. An intramuscular stimulation needling device comprising:
a stepper motor;
a needle configured to poke an affected muscle tissue, the needle operably coupled to the stepper motor, wherein the stepper motor is configured to reciprocate the needle within the affected muscle tissue, wherein in each needling cycle, the needle moves a predetermined distance forwardly in a first half cycle and retracts to original position in a second half cycle; and
a control unit operably coupled to the stepper motor, the control unit configured to:
operate the stepper motor at a first speed;
increase a speed of the stepper motor one or more times consecutively in the first half cycle at predetermined intervals from the first speed to a second speed, wherein second speed greater than the first speed, wherein speed remains constant during an interval of the predetermined intervals; and
decrease the speed of the stepper motor in the second half cycle, in a pattern reverse to the first half cycle, from the second speed to the first speed.
