Research hotspots and effectiveness of repetitive transcranial magnetic stimulation in stroke rehabilitation

Repetitive transcranial magnetic stimulation, as a relatively new type of rehabilitation treatment, is a painless and non-invasive method for altering brain excitability. Repetitive transcranial magnetic stimulation has been widely used in the neurorehabilitation of stroke patients. Here, we used CiteSpace software to visually analyze 315 studies concerning repetitive transcranial magnetic stimulation for stroke rehabilitation from 1999 to 2019, indexed by Web of Science, to clarify the research hotspots in different periods and characterize the gradual process of discovery in this field. We found that four main points were generally accepted:(1) repetitive transcranial magnetic stimulation has a positive effect on motor function recovery in patients with subcortical stroke;(2) it may be more advantageous for stroke patients to receive low-frequency repetitive transcranial magnetic stimulation in the unaffected hemispheres than to receive high-frequency repetitive transcranial magnetic stimulation in affected hemisphere;(3) low-frequency repetitive transcranial magnetic stimulation has become a potential therapeutic tool for patients with non-fluent aphasia after chronic stroke for neurological rehabilitation and language recovery; and(4) there are some limitations to these classic clinical studies, such as small sample size and low test efficiency. Our assessment indicates that prospective, multi-center, large-sample, randomized controlled clinical trials are still needed to further verify the effectiveness of various repetitive transcranial magnetic stimulation programs for the rehabilitation of stroke patients.     

机器人辅助下钻孔减压治疗股骨头坏死与传统手术的对比

文题释义：股骨头缺血性坏死：由创伤性和非创伤性原因引起的股骨头病变的病理过程，临床以髋关节疼痛、功能障碍为主要表现。此病病程长、预后差，易引起股骨头塌陷，引起髋关节退变，股骨头坏死早期可行钻孔减压治疗，后期需要行全髋关节置换。 钻孔减压：即髓芯减压，是在1964年由Arlet和Float首创，空心钻头在克氏针的引导下沿克氏针由股骨大转子外侧向股骨头坏死区域定位，到达股骨头皮质下方。股骨头中间形成孔道使股骨头起到减压的效果。背景：为了延缓早期股骨头坏死的进一步加重，股骨头钻孔减压是一种较好的治疗方法，但传统股骨头钻孔减压手术创伤大。 目的：对比机器人辅助下钻孔减压治疗股骨头无菌性坏死与传统手术疗效的差异。 方法：纳入40例行股骨头无菌性坏死钻孔减压患者进行回顾性对比分析，根据治疗方案分为2组。机器人组在机器人辅助下对18例(26个股骨头)进行股骨头钻孔减压治疗，其中FicatⅠ期13例(18个股骨头)，FicatⅡ期5例 (8个股骨头)；传统手术组共22例患者(29个股骨头)，其中FicatⅠ期15例 (19个股骨头)，FicatⅡ期7例(10个股骨头)。对比2组患者的手术切口、术中透视次数、术中出血量、术中穿刺次数及手术时间，术前及术后1，3，6个月根据Harris评分评估髋关节功能。结果与结论：①所有患者均随访6个月以上；②机器人组术中切口长度、术中出血量、透视次数、术中穿刺次数、手术时间均优于传统组，差异有显著性意义(P < 0.05)；③2组患者术后1，3，6个月Harris评分相比差异均无显著性意义(P > 0.05)；④提示与传统术式相比，机器人辅助下钻孔减压治疗股骨头无菌性坏死的疗效方面并未见明显优势，但其手术切口小，术中透视次数少，创伤小，操作更加安全微创。 ORCID: 0000-0002-1809-7037(罗进) 中国组织工程研究杂志出版内容重点：人工关节；骨植入物；脊柱；骨折；内固定；数字化骨科；组织工程     

建立下肢形态学数据库为匹配术后即装假肢提供参考

文题释义： 术后假肢：现代截肢康复的方法包括手术后安装临时假体，即在完成截肢手术后，医生为患者佩戴合适的临时假体。 大腿影像数据：研究采集的大腿数据包括膝上缘周径、膝上缘5 cm处周径、膝上缘10 cm处周径和膝上缘15 cm处周径，将大腿MRI数据导入3D重建软件，得到大腿截肢范围段表面积、体积。 大腿截肢范围段：为膝关节间隙上10-25 cm。 背景：目前假肢的制作是通过取型、修型、成型3个步骤完成的，由于修型过程是人工完成，与临床技师的经验技术密切相关，制作出来的假肢不美观，接受腔与残肢很难做到全接触。 目的：收集健康志愿者大腿MRI影像数据，评估成人大腿截肢范围段(膝关节间隙上10-25 cm)的对称性；将MRI影像数据建立成数据库，为下肢截肢患者匹配合适的术后即装假肢提供参考数据。 方法：招募40名健康志愿者，采集基本信息：年龄、身高、体质量、膝上缘周径、膝上缘5 cm处周径、膝上缘10 cm处周径和膝上缘15 cm处周径。所有志愿者对试验方案均知情同意，且得到医院伦理委员会批准。对大腿截肢范围进行三维重建，以模型的表面积、体积为参数，对每一例志愿者大腿进行解剖测量，利用三维逆向工程软件对测量结果进行3D偏差分析，完成大腿形态对称性的定量化和可视化分析。 结果与结论：①同体分析：同一个体左右大腿截肢范围段表面积之间的最大百分差异比不超过0.56%(P=0.109)；左右大腿截肢范围段体积之间最大百分差异比不超过1.19%(P=0.182)；三维偏差分析结果显示，最大平均负偏差为-1.47 mm，最大平均正偏差为1.14 mm。40例受试者的3D偏差分布78.02%在2 mm以内，20.97%在2.1-3.0 mm，仅1.01%大于3 mm。②异体分析：三维偏差分析结果显示，最大平均负偏差为-1.97 mm，而最大平均正偏差为1.89 mm。③提示成人双侧大腿截肢范围具有高度的解剖学对称性；当2名成人的膝上缘周径、膝上缘5 cm处周径、膝上缘10 cm周径和膝上缘15 cm处周径分别都相差在2 cm以内时，则认为这2名成人双侧大腿截肢范围段表面轮廓具有高度相似性，与性别、身高和体质量无关。 ORCID: 0000-0001-6838-3042(伍笑棋) 中国组织工程研究杂志出版内容重点：人工关节；骨植入物；脊柱；骨折；内固定；数字化骨科；组织工程     

Postural instability in Parkinson’s disease: Review and bottom-up rehabilitative approaches

The aims of this narrative review are to provide scientific support to characterize the postural instability commonly observed in Parkinson’s disease (PD), and to emphasize how bottom-up rehabilitation programs stimulating the sole of the foot can improve postural stability in PD. Postural instability is a typical characteristic of individuals with PD, which increases the frequency of falls and may worsen their consequences. It thus seems relevant to diagnose these alterations as early as possible, in order to develop specific rehabilitative treatment. The association between sensitivity of the sole of the foot and postural instability in individuals with PD is linked to the key role of peripheral alterations of the sensorimotor system in balance and motor symptoms. By enhancing sensory feedback coming from the feet, bottom-up stimulation allows patients to improve their sensorimotor control. In clinical practice, health practitioners can use sensory stimulation to improve postural control. By improving postural stability, a decrease in fall risk can be achieved and the secondary impairments associated with falls prevented.     

Efficacy of RehaCom cognitive rehabilitation software in activities of daily living,attention and response control in chronic stroke patients

BackgroundOur world is unfortunately facing a huge number of stroke. Attention, response control and activities of daily living (ADL) are important cognitive functions affected by stroke. In line with this explanation, we aimed to investigate the effect of RehaCom rehabilitation software on ADL, attention and response control in chronic stroke patients with damage to middle and anterior cerebral arteries.MethodFor selecting participants, among chronic stroke patients who referred to our special rehabilitation clinic for patients with stroke, fifty patients selected. Participants were assigned to control (n = 25) and experimental (n = 25) groups. The experimental group was compared with the control group before and after using RehaCom (ten 45-min sessions in five weeks).ResultsThere is a significant enhancement in ADL, attention and response control scores in the experimental group compared with the control group. In fact, treatment with RehaCom significantly improved the score of all studied variables in chronic stroke patients.ConclusionsIn conclusion, RehaCom cognitive rehabilitation software has improvement effect on ADL, attention and response control in patients with chronic stroke. Our study reveals a new information about the efficacy of computerized training in the rehabilitation of stroke patients.     

Establishment of a novel rehabilitation program for patients with dropped head syndrome: Short and intensive rehabilitation (SHAiR) program

The pathophysiology of dropped head syndrome (DHS) remains unknown, and its treatment algorithm and indication are not standardized. Here, we established a novel rehabilitation program, short and intensive rehabilitation program for DHS (SHAiR program), consisting of cervical paraspinal muscles exercise, range of motion exercise, cervical and thoracic mobilization, deep cervical flexor muscle exercise, hip lift exercise, anterior pelvic tilt exercise, and walking exercise. The aim of this study was to evaluate the clinical effectiveness of this program. We reviewed clinical outcomes for five consecutive patients with DHS who underwent the SHAiR program (SHAiR group). The outcomes were compared with those of other five patients with DHS who received exercise instruction (control group). Demographic data, the duration from onset of DHS, the apex of sagittal kyphosis on the lateral radiographs, and clinical outcomes including the ability to maintain normal horizontal gaze, chin brow vertical angle, and numerical rating scale (NRS) were evaluated at the initial visit and final follow-up at 7.5 months. There was no significant difference between the two groups in terms of demographic and radiographic data. The ability of horizontal gaze and NRS of cervical pain improved rapidly for all five patients in the SHAiR group as compared to no improvement for all patients in the control group. Rehabilitation for DHS was considered effective not only for localized rehabilitation such as exercise for training cervical extensor muscle function but also exercises for thoracolumbar posture improvement and the psoas muscle.     

Paul Cololian (1869–1956) : membre de la Société Médico-Psychologique (1902) et fondateur de l’Union des Médecins Arméniens de Paris (1920) et de la Croix-Rouge Arménienne de Paris (1922) (Partie I)

Maksoud Boghos Cololian was born December 12, 1869 in Ortakeuy. It was a suburb of Constantinople. The young Maksoud Boghos was sent to the Armenian school of Berberian when he is expected to learn to read and write in. It was here he developed a taste for litterature and the knowledge of the French language thanks to a thorough instruction. When he completed his secondary schooling, he left Armenia for France. In September 1889, he registered at the faculty of medicine of Paris. Extern in 1891 then intern from the asylums of the Seine (1894), he was appointed doctor of medicine in 1898. Cololian acquired a deep knowledge of psychiatry under the direction of great specialists (Taguet, Briand, Magnan, Garnier). Member of the Société Médico-Psychologique in 1902, his happy memories of his non-residential internship in the department of Nicolas Augustin Gilbert (1858–1927) led him to practice general medicine. That is the speciality he dedicated to as a liberal, in Paris rue de Ponthieu, without forgetting his training in psychiatry. In the Rosenwald Book, his speciality was neuropsychiatry. Considering he was a former Ottoman subject and volunteer since the beginning of hostilities in 1914, Cololian became immediately naturalized French with the title of assistant major physician medical. He was appointed head physician of the physiotherapy centers of Versailles (VR 69 and 74), Grignon and the Officers’ Hospital at Versailles. Also, he named himself Paul. He took care of war-wounded and became a precursor in the field of mechano-therapeutic on one hand, and for the measurement of impotence and infirmities one the other hand. In 1918, Cololian was decorated with the Legion of Honor by Raymond Poincaré (1860–1934) himself. Several times laureate of the Academy of Medicine and the Institute, Cololian wrote articles or memories on semiology and psychiatric treatment. He was with P. Garnier the author of a treatise on therapeutics of mental and nervous diseases (1901). Author of chronic hunting in the newspaper “Le Figaro”, medical and scientific popularization in the review “Guérir” and “La Femme et l’Enfant” and too informal written in “Les Annales politiques et littéraires”, Cololian published various articles or analyzes on studies based on morbid psychological constitutions from characters in literature, plays, movies or politics (Emma Bovary, Marie Lafarge, Hitler…). In his psychiatric and psychoanalytic reading of Flaubert's Madame Bovary, Cololian asserted that the creator of Freudianism was Flaubert. Regarding psychoanalysis, he felt Freud's theory had been taken too far by the founder and mostly by his students.
