| Abstract: | This study analyzed subjective sensations caused by DBS pulse‐generator and lead‐extensions in relation with objectively measured parameters. In 50 patients implant‐related sensations were evaluated. The pulse‐generator mobility was video‐analyzed. Insufficient lead‐extension/pulse‐generator tolerability (72%/84%) was documented. Furthermore, 54% of the patients described movement impairments and 48% cosmetic deformity. High body mass index (BMI) was associated with low lead‐extension related pain (P < 0.001). High generator mobility resulted in high lead‐extension related pain (P < 0.001). Compared with lead‐extension type 7482, type 7495 showed less lead‐extension related pain (P = 0.0138), we suppose secondary to surgical tunneling instruments with a larger tip diameter. The lead‐extension path with one tissue tunnel for both lead‐extensions had 36% lead‐extension related pain versus 11% for the path with one single tunnel for each lead‐extension. Smaller pulse‐generators for better cosmetic results, surgical procedures using larger tunneling instruments and one single tunnel for each lead‐extension would provide better results forpatients with BMI <30. © 2008 Movement Disorder Society |
