Lower back pain ( LBP ) is pain felt lower back area . Difficulties when straightened after bending due to the onset of numbness or pain is a symptom or complaint is very common on the problem of lower back pain or lower back pain ( LBP ) . To overcome these problems, the author makes a simulation tool that can overcome disease therapy lower back pain ( LBP ). To overcome these problems, the author makes a simulation tool that can overcome disease therapy lower back or Lower Back Pain ( LBP ) The tool is a " Simulation Therapy Massage Based Microcontroller ATMega 8535 " , with a massage that utilizes vibration motor can be a solution to overcome these problems . After a thorough study of literature and experimental " Simulation Therapy Massage Based Microcontroller ATMega 8535 " perform the accuracy of timer with stopwacth. Accuracy of the results of measurements performed timers amounted to 99.94%, with an error of 0.06%.
