We evaluated the implantable 4-channel stimulator ActiGait, which selectively and directly stimulates the peroneal nerve. In addition, it bypasses the need for surface electrodes and cables. Methods: Walking speed (10-meter gait test, [m/s]) and walking endurance (6-minute gait test [m/6min]) of 5 patients were tested prior to, as well as 6 and 12 weeks after, the implantation of the ActiGait implantable drop foot stimulator system. In addition, ankle joint angles were assessed during specific phases of the gait cycle, i.e. initiation angle (IA) at the first contact of the foot to the floor, initial plantar flexion (IPF), dorsiflexion (DF) and final plantar flexion (FPF) in [degrees] during stance phase. The ankle joint angles were measured at baseline and 12 weeks after ActiGait implantation. Results: At the first follow-up, patients' gait speed was found to have increased (0.55; 0.77 m/s) as had walking endurance (211; 260 m). Improvement in gait speed (0.55; 0.77 m/s) and endurance (214; 248 m) was still present after 12 weeks. In addition, gait analysis after 12 weeks revealed a nearly normal physiological initiation angle (113 degrees vs 122 degrees) and an increase in the initial plantar flexion (7 degrees vs. 0 degrees). The initiation angle (IA) represents a well-suited parameter for adequate pre-positioning of the foot at the beginning of the stance phase and is necessary to prevent stumbling and falling. Furthermore, IA is identical to the maximum achieved dorsiflexion during the swing phase of gait. Thus, analysis of the IA of subjects walking with the implantable drop foot stimulator systems ActiGait is particularly useful in showing that the implantable system restores the IA towards physiological ankle movements. Conclusion: The ActiGait system increased gait speed, walking endurance and the physiology of important ankle joint kinematics. This is most likely a result of ankle dorsiflexion by active peroneal stimulation during the swing phase of gait and optimized prepositioning (IA) of the foot at the beginning of stance phase. The ActiGait system represents a therapeutic option for the treatment of patients suffering drop foot due to a cerebrovascular insult."],["dc.identifier.doi","10.3233/RNN-120283"],["dc.identifier.isi","000324262100004"],["dc.identifier.pmid","23756541"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/31099"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Ios Press"],["dc.relation.issn","0922-6028"],["dc.title","Towards physiological ankle movements with the ActiGait implantable drop foot stimulator in chronic stroke"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Lysis of the blood clot applying recombinant tissue-type plasminogen activator (rtPA) by an intrahematomal catheter is a minimally invasive treatment option, currently being under investigation in a randomized trial. The center position of the catheter in the hematoma is believed to be crucial for an optimal clot lysis. To achieve this objective, frame-based stereotaxy and frameless stereotaxy with guidance of an articulated arm were used. Recently, a preregistered stylet for direct navigation, alleviating the need of guidance, became available. In this study, we evaluated the relative error (RE) describing the deviation of the catheter from the ideal center position in the clot and compared the accuracy of catheter placement using frameless stereotaxy or the novel preregistered stylet. The intrahematomal catheter position was evaluated in three dimensions in 89 patients with spontaneous supratentorial ICH. Frameless stereotaxy with guidance of an articulated arm was performed in 50 patients. The preregistered stylet was used in 39 patients. The catheter position was evaluated using a RE calculating the distance perpendicular to the center of the catheter in relation to the hematoma's diameter. The mean hematoma volume was 51.4 ml. Forty-four out of 89 hematomas were deep-seated. Intraventricular blood was found in 59 patients. The RE of the catheter position was lower in the stylet group in comparison to the frameless stereotaxy group (mean 0.57 vs. 0.90; p = 0.0018). There was no difference between deep-seated and lobar hematomas with regard to the accuracy of catheter placement (p = 0.62). The RE is a robust measure for describing intrahematomal catheter position. The preregistered stylet facilitates a satisfactory catheter placement and is a viable alternative to frameless stereotaxy and guidance with the articulated arm."],["dc.identifier.doi","10.1007/s12975-014-0326-1"],["dc.identifier.isi","000336336200011"],["dc.identifier.pmid","24470086"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/33363"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1868-601X"],["dc.relation.issn","1868-4483"],["dc.title","Catheter Placement for Lysis of Spontaneous Intracerebral Hematomas: Is a Navigated Stylet Better Than Pointer-Guided Frameless Stereotaxy for Intrahematomal Catheter Positioning?"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The exact knowledge of these locations is crucial for planning of neurosurgical procedures. In this study, we have used robot-assisted image-guided transcranial magnetic stimulation (Ri-TMS) to elicit MEP response recorded for individual muscles and reconstruct functional motor maps of the primary motor cortex. One healthy volunteer and five patients with intracranial tumors neighboring the precentral gyrus were selected for this pilot study. Conventional MRI and fMRI were obtained. Transcranial magnetic stimulation was performed using a MagPro X100 stimulator and a standard figure-of-eight coil positioned by an Adept Viper s850 robot. The fMRI activation/Ri-TMS response pattern were compared. In two cases, Ri-TMS was additionally compared to intraoperative direct electrical cortical stimulation. Maximal MEP response of the m. abductor digiti minimi was located in an area corresponding to the \"hand knob\" of the precentral gyrus for both hemispheres. Repeated Ri-TMS measurements showed a high reproducibility. Simultaneous registration of the MEP response for m. brachioradialis, m. abductor pollicis brevis, and m. abductor digiti minimi demonstrated individual peak areas of maximal MEP response for the individual muscle groups. Ri-TMS mapping was compared to the corresponding fMRI studies. The areas of maximal MEP response localized within the \"finger tapping\" activated areas by fMRI in all six individuals.

Assuming micro-communications between the cyst and thecal sac resulting in a valve mechanism and trapping of CSF as a pathomechanism, microsurgical fenestration from the cyst to the thecal sac was performed to achieve free CSF communication. Methods In 13 consecutive patients (10 female, 3 male), MRI revealed sacral perineural cysts and excluded other pathologies. Micro-communication between the thecal sac and the cysts was shown by delayed contrast filling of the cysts on postmyelographic CT. Surgical fenestration achieved free CSF communication between the thecal sac and cysts in all patients. The patient histories, follow-up examinations and self-assessment scales were analyzed. Symptoms at initial presentation included lumbosacral pain, pseudoradicular symptoms, genital pain and urinary dysfunction. Mean follow-up was 10.7 +/- 6.6 months. Findings Besides one CSF fistula, no surgical complications were observed. Five patients did not improve after surgery\\; in four of these cases multiple cysts were found, but small and promptly filling cysts remained untreated. Seven patients reported lasting benefit following surgery\\; three of these had single cysts, and all had cysts >1 cm. One patient initially benefited from cyst fenestration but experienced recurrent pain within 2 months postoperatively. Re-myelography revealed delayed contrast filling of the recurrent cyst\\; however, surgical revision did not lead to an improvement despite successful fenestration and collapse of the cyst revealed by postoperative imaging. Conclusions Microsurgical fenestration of sacral perineural cysts to the thecal sac is a surgical approach that has shown success in the treatment of lumbosacral pain, pseudoradicular symptoms, genital pain and urinary dysfunction associated with sacral perineural cysts.
