  • Finite Element Analysis of Temperature Field of Retina by Electrical Stimulation with Microelectrode Array

    We studied the influence of electrode array parameters on temperature distribution to the retina during the use of retinal prosthesis in order to avoid thermal damage to retina caused by long-term electrical stimulation. Based on real epiretinal prosthesis, a three-dimensional model of electrical stimulation for retina with 4×4 microelectrode array had been established using the finite element software (COMSOL Multiphysics). The steady-state temperature field of electrical stimulation of the retina was calculated, and the effects of the electrode parameters such as the distance between the electrode contacts, the materials and area of the electrode contact on temperature field were considered. The maximum increase in the retina steady temperature was about 0.004℃ with practical stimulation current. When the distance between the electrode contacts was changed from 130 μm to 520 μm, the temperature was reduced by about 0.006℃. When the contact radius was doubled from 130 μm to 260 μm, the temperature decrease was about 0.005℃. It was shown that there were little temperature changes in the retina with a 4×4 epiretinal microelectrode array, reflecting the safety of electrical stimulation. It was also shown that the maximum temperature in the retina decreased with increasing the distance between the electrode contacts, as well as increasing the area of electrode contact. However, the change of the maximum temperature was very small when the distance became larger than the diameter of electrode contact. There was no significant difference in the effects of temperature increase among the different electrode materials. Rational selection of the distance between the electrode contacts and their area in electrode design can reduce the temperature rise induced by electrical stimulation.

  • Effect of Mongolian medicine fumigation combined with sciatic nerve and rectal probe pelvic floor electrical stimulation on muscle spasticity of cervical spinal cord injury

    ObjectiveTo observe the effect of Mongolian medicine fumigation combined with sciatic nerve and rectal probe electrical stimulation on muscle spasticity of spinal cord injury.MethodsBetween January 2012 and January 2018, a total of 65 patients with muscle spasticity after spinal cord injury were randomly divided into two group: the observation group (32 cases) and the control group (33 cases). The patients in the observation group were treated with Mongolian medicine (Wu Wei Gan Lu-Decoction) fumigation combined with sciatic nerve and rectal probe electrical stimulation, while the patients in the control group were treated with medicine, physical therapy, and exercise therapy. Both two groups were treated for 8 weeks. The patients were scored with Ashworth Score, American Spinal Injury Association (ASIA) score, and Barthel Index before and after treatment.ResultsThe pre-treatment ASIA scores (light touch sensation, pain sensation, and muscle strength) and Barthel Index of the two groups were not statistically significant (P>0.05). The post-treatment ASIA scores and Barthel Index of both groups performed significantly better than the pre-treatment levels (P<0.05). The post-treatment ASIA muscle strength item was 58.55±10.83 in the observation group and 50.69±11.32 in the control group (P<0.05). The post-treatment Barthel Index was 74.22±11.53 in the observation group and 68.46±9.92 in the control group (P<0.05). The effective rate in the observation group was significantly better than that in the control group (84.4% vs. 60.6%, P<0.05). Conclusion Mongolian medicine fumigation combined with sciatic nerve and rectal probe electric stimulation could improve the muscle spasticity of spinal cord injury and patients’ ability of daily life effectively.

  • Effects of transcranial direct current stimulation combined with virtual reality training on upper limb function of stroke patient: a pilot randomized controlled single-blind trial

    ObjectiveTo investigate the effects of transcranial direct current stimulation (tDCS) combined with virtual reality (VR) on upper limb dysfunction of stroke patients.MethodsPatients with stroke who were hospitalized in the Department of Rehabilitation Medicine, the Third Affiliated Hospital of Sun Yat-Sen University from July 2018 to January 2020 were selected. The patients were divided into tDCS group, VR group and combined treatment group by random number table method. All three groups received conventional rehabilitation treatment. Based on this, tDCS group received 2.0 mA tDCS treatment, VR group received 20 min VR treatment, and combined treatment group received the same tDCS and VR treatment. Before and 4 weeks after treatment, the Fugl-Meyer assessment-upper limb (FMA-UL), Wolf motor function test (WMFT) and modified barthel index (MBI) were used to evaluate the upper limb motor function and activities of daily life (ADL) of the three groups.ResultsA total of 45 patients were included, 15 in each group. No adverse reactions or fall off occurred during the treatment. Before treatment, there were no significant difference in FMA-UL, WMFT-Times, WMFT functional ability scores (WMFT-FAS), and MBI between the three groups (P>0.05). After 4 weeks of treatment, the FMA-UL, WMFT-Times, WMFT-FAS, and MBI scores of the three groups were significantly improved compared with those before treatment (P<0.05); the MBI score of the combination treatment group was significantly better than the tDCS group and VR group, and the FMA-UL was significantly better than the tDCS group, and the differences were statistically significant (P<0.05). Also, there were no significant differences in the improvement of FMA-UL, WMFT-Times, WMFT-FAS, and MBI scores between the tDCS group and the VR group (P>0.05); the differences of FMA-UL, WMFT-Times, WMFT-FAS, and MBI scores before and after treatment in the combined treatment group, which were significantly better than those in tDCS group and VR group (P<0.05). ConclusiontDCS combined with virtual reality can significantly improve the upper limb motor function and ADL ability of stroke patients, and the effect is superior to tDCS or VR treatment solely.

  • CLINICAL ANALYSIS OF ELECTRICAL STIMULATION THRESHOLD OF NERVE FASCICLE DURING SELECTIVE POSTERIOR RHIZOTOMY

    Abstract This experiment was to study the feasibility from direct observation of muscle contraction of the lower extremity fromelectrical stimulation threshold of nerve fascicle in identifying the Iα intrafusal afferent fibers during selective posterior rhizotomy (SPR) and to investigate the clinical relationship between the muscle spasm and the electrical stimulation of nerve fascicles. The electrical stimulation threshold of all nerve fascicles in 36 cases during SPR were analysed statistically. The results showed that there was a significant difference between the electrical stimulation threshold of the severed nerve fascicles and intact nerve fascicles no matter the nerve root or each posterior nerve rootlet was examined. It was simple and reliable for surgeons to identify correctly the Iα intrafusal afferent fibers intraoperatively from direct observation of the electrical stimulation threshold of nerve fascicle.

  • EXPERIMENTAL STUDY ON COMBINING SELECTIVE RHIZOTOMY OF DIFFERENT ANTIERIOR AND POSTERIOR SACRAL ROOTS FOR RESTORATION OF BLADDER FUNCTION AFTER SPINAL CORD INJURY

    OBJECTIVE: To investigate an alternative procedure for complete denervation of bladder in the supra-cone cord injury to restore the bladder function. METHODS: Sixteen dogs were included in this study after their spinal cords were transected above the cone. They were divided into 6 groups and performed the rhizotomy of L7 to S3 root in different combination respectively. The bladder and urethra pressure change by electrostimulation during operation and cystometrogram change after operation were tested. RESULTS: 1. Electrostimulation study: for bladder innervation, S2was the most important and S1 was secondary. While for urethra innervation, S1 was more important than S2. When the anterior and posterior roots of S1 and S2 were intact with rhizotomy of posterior roots of L7 and S3, stimulated the common or posterior root of S1 and S2, the change of pressure in bladder and urethra was the same. When the anterior roots of S1 and S2 were resected with rhizotomy of posterior roots of L7 and S3, the pressure in bladder and urethra was significant decreased compared to stimulating the corresponding posterior roots. 2. Cystometrogram (CMG) study: in the complete deafferented group, resecting the posterior roots of L7 to S3, the bladder became flaccid. While resecting the posterior root of S2 and anterior root of S1 or, resecting the posterior root of S1 and anterior root of S2, combining with rhizotomy of posterior roots of L7 and S3, the CMG curve was similar to the complete deafferented group. In the S1 and S2 intact group, the bladder became spastic. CONCLUSION: Combining rhizotomy of anterior and posterior sacral root in different level has the same effects on bladder as complete deafferentation.
