title: Patient perspectives on the efficacy of a new kind of rechargeable deep brain stimulators(1).
abstract: OBJECTIVE
  Rechargeable deep brain stimulation (DBS) system with longer battery life has become available for treating movement disorders. However, little information exists about the safety and management after implantation. Therefore, there is an urgent need to evaluate the recharging performance through long-term observations.
  
  
  METHODS
  Fifty-three Parkinson's disease (PD) patients were implanted with a new rechargeable device (G102R, PINS Medical). They were observed at the baseline and 3 months, 6 months and 12 months after surgery, with measurement of the acceptance, frequency, recharging time and feeling during recharging.
  
  
  RESULTS
  The patients with the ages between 34 and 70 (57.64 ± 7.34) years thought the system was very easy to recharge. The favorite time interval for recharging was 1 week, and 10 days and half a month also chosen. Most of the patients spent around 1 hour recharging, with no unacceptable hot feelings reported.
  
  
  CONCLUSIONS
  The PD patients could easily and safely recharge this new rechargeable implantable neurostimulators. Thus, these neurostimulators might be an excellent choice for PD patients.
