Acupuncture combined with mirror therapy for post-stroke dyskinesia: A meta-analysis and systematic review.

BACKGROUND: Dyskinesia is one of the most common complications of stroke. Acupuncture therapy (AT) and mirror therapy (MT) are promising rehabilitation measures for the treatment of post-stroke dyskinesia. Although some studies suggested that AT and MT are effective and safe for dyskinesia, the effects, and safety remain uncertain due to lacking strong evidence. The purpose of this study is to investigate the efficacy and safety of AT combined with MT in the treatment of post-stroke dyskinesia. METHODS: We searched the following databases: PubMed, Web of Science, Cochrane Library, EMBASE, Medline, China Knowledge Network, WANFANG, and China Biomedical Literature Database, from inception to 1 January 2023 to identify eligible studies. Total effective rate, the Fugl-Meyer assessment scale (FMA) upper and lower limb scores, modified Barthel index scores, Berg balance scale, modified Ashworth scale, and adverse reactions were adopted as outcome indicators. The Grading of Recommendations Assessment Development and Evaluation system was used by 2 independent reviewers to assess the quality of evidence for the outcome indicators included in the study. The statistical analysis was conducted by RevMan V.5.4 software. RESULTS: A total of 24 randomized controlled studies included 2133 patients with post-stroke dyskinesia were included. The total effective rate of AT combined with MT was more advantageous in the treatment of post-stroke dyskinesia (relative risk = 1.31, 95% confidence interval [CI] [1.22-1.42], Z = 6.96, P < .0001). AT combined with MT was more advantageous for FMA upper limb score (mean difference [MD] = 6.67, 95% CI [5.21-8.13], Z = 8.97, P < .00001) and FMA lower limb score (MD = 3.72, 95% CI [2.81-4.63], Z = 7.98, P < .00001). Meta-analysis showed that AT combined with MT for post-stroke dyskinesia had a more advantageous modified Barthel index score (MD = 9.51, 95% CI [7.44-11.58], Z = 9.01, P < .00001). CONCLUSION: AT combined with MT is effective in improving motor function and daily living ability of patients, especially in improving muscle spasms. However, these results should be regarded with caution given the low quality of evidence for the evaluation results.

Are patients with GBA-Parkinson disease good candidates for deep brain stimulation? A longitudinal multicentric study on a large Italian cohort.

BACKGROUND: GBA variants increase the risk of developing Parkinson disease (PD) and influence its outcome. Deep brain stimulation (DBS) is a recognised therapeutic option for advanced PD. Data on DBS long-term outcome in GBA carriers are scarce. OBJECTIVE: To elucidate the impact of GBA variants on long-term DBS outcome in a large Italian cohort. METHODS: We retrospectively recruited a multicentric Italian DBS-PD cohort and assessed: (1) GBA prevalence; (2) pre-DBS clinical features; and (3) outcomes of motor, cognitive and other non-motor features up to 5 years post-DBS. RESULTS: We included 365 patients with PD, of whom 73 (20%) carried GBA variants. 5-year follow-up data were available for 173 PD, including 32 mutated subjects. GBA-PD had an earlier onset and were younger at DBS than non-GBA-PD. They also had shorter disease duration, higher occurrence of dyskinesias and orthostatic hypotension symptoms.At post-DBS, both groups showed marked motor improvement, a significant reduction of fluctuations, dyskinesias and impulsive-compulsive disorders (ICD) and low occurrence of most complications. Only cognitive scores worsened significantly faster in GBA-PD after 3 years. Overt dementia was diagnosed in 11% non-GBA-PD and 25% GBA-PD at 5-year follow-up. CONCLUSIONS: Evaluation of long-term impact of GBA variants in a large Italian DBS-PD cohort supported the role of DBS surgery as a valid therapeutic strategy in GBA-PD, with long-term benefit on motor performance and ICD. Despite the selective worsening of cognitive scores since 3 years post-DBS, the majority of GBA-PD had not developed dementia at 5-year follow-up.

Physical and well-being effect of scapular kinesio taping combined with conventional physiotherapy in shoulder impingement syndrome: A randomized controlled study.

BACKGROUND: Kinesio taping (KT) is one of the treatment methods used on patients with shoulder impingement syndrome (SIS). There are different results regarding its effectiveness in the literature. OBJECTIVE: To investigate the effects of scapular KT combined with a conventional physiotherapy program on scapular dyskinesia, shoulder pain, upper extremity function, and well-being in patients with SIS. METHODS: The study was conducted with 60 outpatients diagnosed with SIS, aged 40-65 years. The patients were divided into two groups: KT [conventional physiotherapy program + scapular KT (targets scapular retraction and is applied along the inferior-medial edge of the scapula, starting from the processus coracoids), n= 30] and control [conventional physiotherapy program, n= 30]. In before- and after-treatment evaluations, the Lateral Scapular Slide Test (LSST) for scapular dyskinesia, a Visual Analogue Scale (VAS) for shoulder pain, and the Disabilities of the Arm, Shoulder, and Hand (DASH) for upper extremity function were used. In addition, at the end of treatment, a Kinesio taping Satisfaction Survey, created by the researchers, was filled out by the KT group for the assessment of well-being. RESULTS: The interaction effect of Group*Time was not statistically significant in all outcome measures (p> 0.05). However, the main effect of both group and time was statistically significant in the DASH-Function/Symptom, VAS-Rest, VAS-Activity, and VAS-Night (p< 0.05). Moreover, only the main effect of time was statistically significant in LSST-1 and LSST-3 (p< 0.05). In the KT group, the satisfaction level was 8.50 ± 1.69 and the recommendation level was 8.72 ± 1.81. CONCLUSION: Both conventional physiotherapy programs and additional scapular KT improved scapular dyskinesia, reduced pain, and increased the upper extremity function. Adding scapular KT to treatment did not change the results, but it had positive psychological effects and yielded a high satisfaction rate.

Effect of acupuncture treatment on nonketotic hyperglycemic hemichorea-hemiballismus: a case report.

Nonketotic hyperglycemic hemichorea-hemiballismus is a rare syndrome in the clinic, and treatment is often delayed. Hypoglycemic therapy is the most widely used and effective treatment, but some patients experience a slower improvement. Other symptomatic treatment medicines have some degree of side effects. Acupuncture treatment is beneficial for hemichorea-hemiballismus. A male patient, aged 59 years, first visited our hospital outpatient department due to motor agitation with involuntary movements of the right limb. He had a history of type 2 diabetes mellitus and poor blood glucose control. His serum glucose was 26.5 mmol/L (normal: 4.4-6.1 mmol/L), and magnetic resonance imaging demonstrated an irregular area of high signal intensity in T1-weighted imaging, low signal intensity on T2-weighted imaging, and high signal intensity in the left corpus striatum in T2-FLAIR imaging. Hospitalization was recommended for the patient. After ruling out other possibilities, he was eventually diagnosed with nonketotic hyperglycemic hemichorea-hemiballismus. Intensive glycemic control was immediately started with subcutaneous injection and acupuncture treatment at "governor vessel 13 acupoints", and the involuntary movements completely disappeared on the ninth day of hospitalization. The pathophysiology of nonketotic hyperglycemic hemichorea-hemiballismus is unclear. Different patient histories lead to different brain tissue conditions, and relapses and uncontrolled blood glucose add difficulties to treatment. According to Traditional Chinese Medicine theory, insufficient kidney essence leads to brain dystrophy and causes the symptoms of hemichorea-hemiballismus. Research evidence has shown that acupuncture at "governor vessel 13 acupoints" has a beneficial treatment effect on nonketotic hyperglycemic hemichorea-hemiballismus.

Deep Brain Stimulation for the Treatment of Hemichorea: Case Series and Literature Review.

Background: Hemichorea (HC) and its severe form hemiballismus (HB) are rare movement disorders which can be medically refractory to treatments and may need surgical intervention. Case Report: We report 3 patients with HC-HB who had meaningful clinical improvement with unilateral deep brain stimulation (DBS) of the globus pallidus interna (GPi). We identified 8 prior cases of HC-HB treated with GPi-DBS, and a majority of these patients experienced significant improvement in their symptoms. Discussion: GPi-DBS can be considered in medically refractory HC-HB in carefully selected patients. However, data is limited to small case series and further studies are needed.

Long-Term Follow-Up of Pediatric Patients with Dyskinetic Cerebral Palsy and Deep Brain Stimulation.

BACKGROUND: Deep brain stimulation (DBS) has been increasingly used in the management of dyskinetic cerebral palsy (DCP). Data on long-term effects and the safety profile are rare. OBJECTIVES: We assessed the efficacy and safety of pallidal DBS in pediatric patients with DCP. METHODS: The STIM-CP trial was a prospective, single-arm, multicenter study in which patients from the parental trial agreed to be followed-up for up to 36 months. Assessments included motor and non-motor domains. RESULTS: Of the 16 patients included initially, 14 (mean inclusion age 14 years) were assessed. There was a significant change in the (blinded) ratings of the total Dyskinesia Impairment Scale at 36 months. Twelve serious adverse events (possibly) related to treatment were documented. CONCLUSION: DBS significantly improved dyskinesia, but other outcome parameters did not change significantly. Investigations of larger homogeneous cohorts are needed to further ascertain the impact of DBS and guide treatment decisions in DCP. © 2023 The Authors.

15-Year Subthalamic Deep Brain Stimulation outcome in a Parkinson's disease patient with Parkin gene mutation: a case report.

INTRODUCTION: Parkinson's Disease (PD) patients with Parkin gene (PRKN) mutations show good response to subthalamic deep brain stimulation (STN-DBS). Currently, the longest follow-up available of these patients is 6 years. We report a very long-term outcome (more than 15 years) of a STN-DBS-treated patient with a compound heterozygous deletion of exons 3 and 11 of the PRKN gene. CASE REPORT: In 1993, a 39-year-old male was diagnosed with PD after the onset of resting tremor. Levodopa was started, and during the following 10 years, he reported good motor symptoms control, with only mild modification of levodopa intake and pramipexole introduction. In 2005, he developed disabling motor fluctuations and dyskinesia. In 2007, he underwent bilateral STN-DBS, with a marked improvement of motor symptoms and fluctuations during the following years. After 6 years, he reported mild motor fluctuations, improved after stimulation and treatment modifications. After 10 years he showed diphasic dyskinesias, feet dystonia, postural instability, and gambling (resolved after pramipexole discontinuation). In 2018, he developed a non-amnestic single-domain mild cognitive impairment (MCI). In 2023, after more than 15 years of STN-DBS, motor symptoms and fluctuations are still well controlled. He reports mild dysphagia, mild depression, and multiple-domain MCI. His quality of life is better than before surgery, and he still reports a subjective significant improvement from STN-DBS. CONCLUSION: Confirming the very long-term efficacy of STN-DBS in PRKN-mutated patients, our case report underlines their peculiar suitability for surgical treatment.

[Functional (Psychogenic) Movement Disorder Focusing on Involuntary Movements: A Review].

Functional neurological disorders differ from malingering/factitious disorders and are diagnosed based solely on careful history taking and neurological evaluation. Some clinical characteristics, including distractibility, entrainability, and variability are important to identify the positive physical signs that indicate functional alterations. Thorough investigations are not essential to exclude organic pathologies, whereas electrophysiological and radiological findings are sometimes useful. Neurologists play an important role when they explain the diagnosis to the patient. The explanation itself may be therapeutic, when delivered successfully and may help patients to understand the nature and mechanisms underlying their movement disorder. A multidisciplinary team approach, including coordination between rehabilitation therapists and psychotherapists may produce positive treatment outcomes, particularly in movement disorder centers. In this article, we discuss some functional neurological disorders, including those in patients with functional movement disorders (involuntary movements) together with video presentations.

Deep brain stimulation for Parkinson's disease.

Parkinson's disease (PD) is a progressive neurodegenerative illness with both motor and nonmotor symptoms. Deep brain stimulation (DBS) is an established safe neurosurgical symptomatic therapy for eligible patients with advanced disease in whom medical treatment fails to provide adequate symptom control and good quality of life, or in whom dopaminergic medications induce severe side effects such as dyskinesias. DBS can be tailored to the patient's symptoms and targeted to various nodes along the basal ganglia-thalamus circuitry, which mediates the various symptoms of the illness; DBS in the thalamus is most efficient for tremors, and DBS in the pallidum most efficient for rigidity and dyskinesias, whereas DBS in the subthalamic nucleus (STN) can treat both tremors, akinesia, rigidity and dyskinesias, and allows for decrease in doses of medications even in patients with advanced stages of the disease, which makes it the preferred target for DBS. However, DBS in the STN assumes that the patient is not too old, with no cognitive decline or relevant depression, and does not exhibit severe and medically resistant axial symptoms such as balance and gait disturbances, and falls. Dysarthria is the most common side effect of DBS, regardless of the brain target. DBS has a long-lasting effect on appendicular symptoms, but with progression of disease, nondopaminergic axial features become less responsive to DBS. DBS for PD is highly specialised; to enable adequate selection and follow-up of patients, DBS requires dedicated multidisciplinary teams of movement disorder neurologists, functional neurosurgeons, specialised DBS nurses and neuropsychologists.

Resolving dyskinesias at sustained anti-OCD efficacy by steering of DBS away from the anteromedial STN to the mesencephalic ventral tegmentum - case report.

Here we describe therapeutic results in a female patient who underwent bilateral slMFB DBS for OCD. During a 35-month long course of stimulation, she suffered from stimulation-induced dyskinesia of her right leg which we interpreted as co-stimulation of the adjacent anteromedial subthalamic nucleus (amSTN). After reprogramming to steer the stimulation away from the amSTN medial into the direction of the mesencephalic ventral tegmentum (MVT which contains the ventral tegmental area, VTA), the dyskinesias disappeared. Remarkably, anti-OCD efficacy in the presented patient was preserved and achieved with a bilateral stimulation which by our imaging study fully avoided the amSTN.

Inter-rater reliability of scapular dyskinesis classification in overhead athletes by entry-level physical therapy students.

BACKGROUND: Scapular dyskinesis (SD) is a dysfunction associated with shoulder pathologies in overhead athletes and its classification is highly complex, especially in entry-level physical therapy students. OBJECTIVE: This research aimed to determine the effect of a video training method on inter-rater reliability of physical therapy entry-level students with no clinical experience while performing SD ratings under 4-type, severity, and 'yes or no' criteria in overhead athletes. METHODS: A total of 49 overhead athletes were evaluated by video recordings in posterior view of lifting tasks. Two entry-level students without clinical experience performed SD classifications according to previously mentioned criteria on both scapula in two separate sessions, with 1 week of difference. Data analysis was conducted based on the kappa coefficient (k) and its confidence intervals (CI). RESULTS: The 'yes or no' criteria present better results than the 4-type and severity criteria. In addition, a better inter-rater agreement is evidenced in the second measurement compared to the first one. Furthermore, the k coefficients reach values like those achieved by experienced evaluators. CONCLUSION: Video training settings for scapular dyskinesis rating in entry-level physical therapist students with no clinical experience allows better inter-rater reliability values.

Deep Brain Stimulation of the Pallidofugal Pathways to Rescue Severe Life-Threatening Dyskinesias after STN-DBS Lead Implantation.

We present a patient with severe life-threatening dyskinesias due to a persistent microlesion effect after STN-DBS electrode implantation. The pallidofugal pathways were identified using patient-specific tractography, and steering the current toward this white matter structure resulted in complete resolution of the severe dyskinesias.

Comparison between dry needling plus manual therapy with manual therapy alone on pain and function in overhead athletes with scapular dyskinesia: A randomized clinical trial.

Muscles' trigger points can induce scapular dyskinesia (SD) which interferes with overhead athletes' professional training. We aimed to evaluate effects of dry needling (DN) alone and plus manual therapy (MT) on pain and function of overhead athletes with SD. 40 overhead athletes (15 male, 25 female) aged 18-45 with at least 3 points Numeric Rating Scale (NRS) pain intensity during training were recruited and randomly allocated to the treatment group: MT followed by DN on trigger points of Subscapularis, Pectoralis minor, Serratus anterior, upper and lower Trapezius muscles; or the control group: MT alone. The effect of shoulder trigger points DN plus MT with MT alone on pain, function, Pain Pressure Threshold (PPT) and SD in athletes with SD were compared. Both the examiner and the therapist were blinded to group assignment. Both groups were analyzed. Pain, disability and SD were improved in treatment group (P < .05). On the other hand, when only MT was applied, despite reduction in pain and disability (P < .001), scapular slide only improved in hands on waist position. Comparing the differences between groups showed a substantial reduction in pain (P < .001) and disability (P = .02) with significant improvement in scapular dyskinesia in treatment group (P = .02). Moreover, PPT significantly increased in the control group (P = .004). No adverse effects reported by the participants during this study. DN is an easy and applicable method that can synergistically reduce pain, disability and dyskinesia when it is combined with manual techniques to treat shoulder dysfunctions.

Effects of the Proprioceptive Neuromuscular Facilitation Technique on Scapula Function in Office Workers with Scapula Dyskinesis.

Background and Objectives; Proprioceptive neuromuscular facilitation (PNF) are effective in improving and maintaining Range of motion(ROM), increasing muscular strength and power, and increasing athletic performance, especially after exercise. The scapula patterns defined in PNF are activated within the upper extremity patterns and scapula motions together. Proper function of the upper extremities requires both motion and stability of the scapula. The purpose of this study was to compare the effects of scapula stabilization exercise training involving muscle strengthening, muscle balance, and movement control exercises on office workers with scapula dysfunction. Materials and Methods: A total of 42 office workers with scapula dyskinesis were recruited and randomly divided into three groups: muscle strengthening exercise group (n = 14), muscle balance exercise group (n = 14), and movement control exercise group (n = 14). The participants underwent 18 sessions (25 min/session, 3 days a week for 6 weeks) of training involving the three types of exercises. Results: The measurement outcomes included the scapula index, measured using a digital Vernier caliper; scapula function, evaluated using the Disability of the Arm, Shoulder, and Hand (DASH) outcome questionnaire (pain and performing, work ability, and sports and art activities); and scapulohumeral movements (scapula upward rotation at humeral abduction angles of 0°, 45°, 90°, 135°, and 180°), evaluated using inclinometers. After the exercise intervention, the scapula index (p = 0.002), DASH pain and performing score (p = 0.000), DASH work ability score (p = 0.000), DASH sports and art activity score (p = 0.027), and scapulohumeral movements (scapula upward rotation at 0° (p = 0.013) and 45° (p = 0.043) humeral abduction) showed significantly greater improvements in the movement control group than in the muscle strengthening and muscle balance groups. Conclusions: Thus, proprioceptive neuromuscular facilitation can be used as a rehabilitation intervention for scapula position and movement, pain reduction, and functional improvement in office workers with scapula dyskinesis.

Effects of eye-acupuncture combined with rehabilitation training for poststroke dyskinesia: A protocol for systematic review and meta-analysis.

INTRODUCTION: Poststroke dyskinesia is the most common clinical symptom after stroke, which greatly affects the patients' daily life. Eye-acupuncture is an effective method for stroke. And the rehabilitation training has been widely used for patients suffer from stroke. However, whether eye-acupuncture combined with rehabilitation training has greater clinical efficacy for poststroke dyskinesia is still unknown. Our aim in this systematic review was to evaluate the clinical efficacy of eye-acupuncture combined with rehabilitation training (EACRT) as a treatment for dyskinesia after stroke. METHODS AND ANALYSIS: We will search the following 4 databases of registered trials and 7 electronic databases from inception to March 2021:Cochrane Stroke Group, Cochrane Central Register of Controlled, the World Health Organization International Clinical Trials Registry Platform, the Chinese Clinical Trial Registry; PubMed, MEDLINE, Embase, CNKI, VIP, WanFang, and CBM. All relevant randomized controlled trials focus on EACRT will be included. The primary outcome will be the Fugl-Meyer Assessment. The Secondary outcomes will include Activity of Daily Living, clinical effective rate and the Visual Analogue Score. Two reviewers will independently conduct the Study selection and data extraction. The data synthesis and assessment of risk of bias will be performed by RevMan5.2. ETHICS AND DISSEMINATION: The ethical approval is unnecessary that systematic review is based on published articles other than patients. The results of this meta-analysis will be published in an open access (OA) journal according to the Preferred Reporting Item for Systematic Review and Meta-analysis (PRISMA). PROSPERO REGISTRATION NUMBER: CRD42020168278.

Causes and Predictors of Unplanned Readmission in Cranial Neurosurgery.

OBJECTIVE: A better understanding of the risks and reasons for unplanned readmission is an essential component in reducing costs in the health care system and in optimizing patient safety and satisfaction. The reasons for unplanned readmission vary between different disciplines and procedures. The aim of this study was to identify reasons for readmission in view of different diagnoses in cranial neurosurgery. METHODS: In this single-center retrospective study, adult patients after neurosurgical treatment were analyzed and grouped according to the indication based on International Classification of Diseases and Related Health Problems, Tenth Revision, German Modification diagnosis codes. The main outcome measure was unplanned readmission within 30 days of discharge. Further logistic regression models were performed to identify factors associated with unplanned rehospitalization. RESULTS: Of the 2474 patients analyzed, 183 underwent unplanned rehospitalization. Readmission rates differed between the diagnosis groups, with 9.19% in neoplasm, 8.26% in hydrocephalus, 5.76% in vascular, 6.13% after trauma, and 8.05% in the functional group. Several causes were considered to be preventable, such as wound healing disorders, seizures, or social reasons. Younger age, length of first stay, surgical treatment, and side diagnoses were predictors for unplanned readmission. Diagnoses with an increased risk of readmission were glioblastoma, traumatic subdural hematoma, or chronic subdural hematoma. CONCLUSIONS: Reasons and predictors for an unplanned readmission differ considerably among the index diagnosis groups. In addition to well-known reasons for readmission, we identified social indication, meaning a lack of home care, which is particularly prevalent in oncologic and elderly patients. A transitional care program could benefit these vulnerable patients.

STN versus GPi deep brain stimulation for dyskinesia improvement in advanced Parkinson's disease: A meta-analysis of randomized controlled trials.

BACKGROUND: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) and the globus pallidus internus (GPi) are currently the most common and effective surgical targets for advanced Parkinson's disease (APD). Herein, we conducted a meta-analysis to evaluate the comprehensive efficacy of STN-DBS and GPi-DBS in patients with APD. METHODS: We conducted a systematic search for relevant articles written in English in the Cochrane Library, PubMed, and EMBASE databases through January 2020. Studies comparing the efficacy and clinical outcomes of GPi-DBS and STN-DBS for APD were included and analyzed. RESULTS: Ten eligible trials with a total of 857 patients were included in this meta-analysis. The results showed no significant difference between the STN-DBS and GPi-DBS groups in Unified Parkinson's Disease Rating Scale (UPDRS) III scores during the on and off-medication phases(SMD, 0.1; 95 % CI, -0.04 to 0.25; p = 0.17, on-med), (SMD,-0.12;95 % CI -0.37 to 0.13, p = 0.33,off-med). Dyskinesia scores and the activities of daily living (ADLs) scores during the on-medication phase showed significant differences in favor of GPi stimulation (SMD, 0.16; 95 % CI, 0.01-0.32; P < 0.05)/(SMD, 0.18; 95 % CI, 0.01-0.34; P < 0.05). The ADLs score during the off-medication phase showed no significant difference between the STN-DBS and GPi-DBS groups (SMD, -0.11; 95 % CI, -0.32-0.11; P = 0.33). The LED showed significant differences in favor of STN stimulation (SMD, -0.57; 95 % CI, -0.74-0.40; P < 0.00001). CONCLUSIONS: Both STN and GPi-DBS were equally effective in improving motor dysfunction. STN-DBS was superior for medication reduction, whereas GPi-DBS perhaps led to less dyskinesia and improved the postoperative ADLs (on-medication) in APD patients. Hence, the goals of DBS can be important in the target selection. More studies comparing the adverse events and quality of life between the two targets are needed.

Stimulation-Induced Dyskinesia After Subthalamic Nucleus Deep Brain Stimulation in Patients With Meige Syndrome.

OBJECTIVES: Deep brain stimulation of the subthalamic nucleus (STN-DBS) is increasingly used to treat Meige syndrome (MS) and markedly improves symptoms. Stimulation-induced dyskinesia (SID), which adversely affects surgical outcomes and patient satisfaction, may, however, occur in some patients. This study attempts to explore possible causes of SID. MATERIALS AND METHODS: Retrospectively collected clinical data on 32 patients who underwent STN-DBS between October 2016 and April 2019 were analyzed. Clinical outcomes were assessed pre- and post-surgery, using the Burke-Fahn-Marsden dystonia rating scale (BFMDRS). Patients were divided into a dyskinesia group and a non-dyskinesia group, according to whether or not they experienced persistent SID during follow-up. The coordinates of the active contacts were calculated from post-operative computerized tomography or magnetic resonance imaging, using the inter-commissural line as a reference. At final follow-up, the main stimulatory parameters for further study included pulse width, voltage, and frequency. RESULTS: At final follow-up (mean = 16.3 ± 7.2 months), MS patients had improved BFMDRS total scores compared with pre-surgical scores (mean improvement = 79.0%, p < 0.0001). The mean improvement in BFMDRS total scores in the dyskinesia (n = 10) and non-dyskinesia (n = 22) groups were 81.6 ± 8.8% and 77.9 ± 14.2%, respectively. The mean minimum voltage to induce dyskinesia was 1.7 ± 0.3 V. The programmed parameters of both groups were similar. When compared with the non-dyskinesia group, active stimulatory contact coordinates in the dyskinesia group were inferior (mean left side: z = -2.3 ± 1.7 mm vs. z = -1.2 ± 1.5 mm; p = 0.0282; mean right side: z = -2.7 ± 1.9 mm vs. z = -2.3 ± 1.7 mm; p = 0.0256). The x and y coordinates were similar. CONCLUSION: STN-DBS is an effective intervention for MS, providing marked improvements in clinical symptoms; SID may, however occur in the subsequent programming control process. Comparing patients with/without dyskinesia, the active contacts were located closer to the inferior part of the STN in patients with dyskinesia, which may provide an explanation for the dyskinesia.

Shoulder pain and scapular dyskinesis associated with lower trapezius dysplasia - A case report.

BACKGROUND: Scapular dyskinesis (SD) has been associated with shoulder soft-tissue tightness as well scapular muscle strength and/or activation deficits. Inadequate development of the trapezius muscle (trapezius dysplasia) is a relatively rare condition inconsistently associated with shoulder dysfunction. CASE DESCRIPTION: a 24-year old male complaining of left scapular area pain associated with SD and scapular muscle weakness was noted to present with a smaller ipsilateral lower trapezius (LT). Further inquiry including electromyography, rehabilitative ultrasound imaging (RUSI) and magnetic resonance imaging ruled out nerve palsy and demonstrated a hypoplastic left LT. This led to a greater emphasis on serratus anterior (SA) training along with the addition of neuromuscular electrical stimulation of the LT. OUTCOMES: Following 12 sessions over a 5-month period the patient reported no pain or functional deficits, and was able to resume all recreational activities. The patient's subjective shoulder value increased from 55% to 80%, and LT strength was markedly improved. DISCUSSION: Scapular muscle dysplasia may represent a less recognized cause of SD. A more thorough inspection of scapular muscle shape and orientation, possibly augmented by RUSI may be indicated in patients presenting with SD. Neuromuscular electrical stimulation is a potentially useful modality for addressing scapular muscle activation and strength deficits and future research into its efficacy under these circumstances may be warranted.

Observation for the effect of rTMS combined with magnetic stimulation at Neiguan (PC6) and Sanyinjiao (SP6) points on limb function after stroke: A study protocol.

BACKGROUND: Stroke is the primary cause of adult disability in China, which causes serious personal, family, and social burden. "Central peripheral central" closed-loop rehabilitation theory is proved to be an effective neural rehabilitation model. Based on this theory, repetitive transcranial magnetic stimulation (rTMS) combined with magnetic stimulation of Neiguan (PC6) and Sanyinjiao (SP6) may be an effective treatment for limb dysfunction after stroke. However, the efficacy and mechanism of repetitive magnetic stimulation of M1 region combined with magnetic stimulation of Neiguan and Sanyinjiao points on limb dysfunction after stroke has not been confirmed. METHODS/DESIGN: This study is a prospective, randomized, controlled, open trial. We randomly divided 42 subjects, aged 35 to 80 years, diagnosed with ischemic stroke within 1 month, into 2 groups with a ratio of 1:1. On the basis of this medical treatment, patients in the experimental group received 1 Hz rTMS in M1 area on the contralateral side, and 3 Hz rTMS treatment at Neiguan point and Sanyinjiao point on the affected side. The control group was treated with acupuncture (body acupuncture). All patients were treated once a day and followed up for 10 days. The National Institute of Health Stroke Scale score, simplified fulg Meyer, modified Barthel index, and cortical excitability were evaluated on the day of enrollment and the 10th day of treatment respectively. The modified Barthe index was followed up on the 30th day of treatment, and the adverse reactions were recorded at any time. The mechanism of rTMS will be revealed by Barthe index before treatment, on the 10th day of treatment and on the 30th day of follow-up. The results were analyzed by spss19.0 software, and the quantitative indexes were analyzed by t test and rank sum test. χ test was used for non-grade counting, and rank sum test was used for grade counting. All statistical tests were performed with bilateral test. If P value is less than or equal to .05, the difference will be considered statistically significant. CONCLUSION: The purpose of this study was to determine the effect of repetitive magnetic stimulation of M1 region combined with magnetic stimulation of Neiguan and Sanyinjiao points on limb function after stroke. Through this study, we expect to explore a new scheme for the treatment of poststroke dyskinesia, and prove that compared with rTMS and acupuncture alone, the closed-loop rehabilitation theory based on "center peripheral center" can be more efficient and safe in the treatment of poststroke limb dysfunction. TRIAL REGISTRATION: The trial was registered in China clinical trial registry (http://www.chictr.org.cn/index.aspx), ID: ChiCTR1900026890 (October 25, 2019).
