Abstract: An intramuscular stimulation needling device for chronic pain relief. The needling device can include a stepper motor, a needle, and a control unit. The needle can poke an affected muscle tissue and driven by a stepper motor in reciprocating manner. In each cycle, the needle moves a pre-determined distance forwardly in a first half cycle and retracts to original position in a second half cycle. The control unit can accelerate of the needle one or more times in the first half cycle at spaced intervals and decrease the velocity in the reverse pattern in the second half cycle.
