Table 1 Summary of spiral nerve cuff electrode recipients and observations. Caption: A summary of the 14 spiral nerve cuff electrode recipients. Information about their type of spiral cuff, location of the cuff, implant date, observations regarding performance, and the date of last follow-up are presented. For participants with SCI, the injury level and Abbreviated Injury Scale (AIS) classification is given

From: “Long-term stability of stimulating spiral nerve cuff electrodes on human peripheral nerves”
