Botulinum toxin and conservative treatment strategies in people with cervical dystonia: an online survey.

Isolated cervical dystonia is a focal, idiopathic dystonia affecting the neck muscles. Treatment usually consists of botulinum neurotoxin (BoNT) injections into the dystonic muscles. Our aim is to investigate the use of BoNT treatment and conservative treatments by people living with cervical dystonia. An online survey in English was conducted between June and August 2022. Participants were eligible to participate if they were living with cervical dystonia, were over 18 years old and could read and understand English. The survey consisted of demographic questions, characteristics of dystonia, questions relating to BoNT use and the perceived utility of conservative treatments. The data were analysed descriptively, and open-ended questions were grouped into similar topics represented by direct quotes. We received 128 responses from people with cervical dystonia, with an average age of 59 years and 77% women. Most participants (52%) described their cervical dystonia as mild to moderate with an average pain score of 5/10. Eighty-two (64%) participants were having regular BoNT injections, with overall positive perceived effects. Common activities reported to improve the symptoms were the use of heat packs, massage, relaxation, physiotherapy and participation in general exercise. Common coping strategies reported were getting sufficient rest, having the support of friends and family, and remaining engaged in enjoyable hobbies. We found that most participants received regular BoNT injections and that heat packs, exercise, massage, physiotherapy and relaxation were mostly perceived as effective in reducing the symptoms of cervical dystonia.

Secondary dystonia following parenchymal brain tumors.

BACKGROUND: Secondary dystonia has been associated with diverse etiologies. Dystonia associated with brain tumors has not been well characterized. OBJECTIVES: To characterize dystonia and relationship with parenchymal brain tumors. METHODS: We present six patients (1.03%) with dystonia related to parenchymal brain tumors, among 580 screened cases. RESULTS: Contralateral hemidystonia was observed in four cases, followed by focal limb (n = 1) and cervical dystonia (n = 1). Dystonia presented during the phase of tumor growth in four cases, and following tumor treatment in two, one case had re-emergent dystonia. Tumors were low-grade (WHO I or II) and located in the basal ganglia (n = 3), cortical areas (n = 2), thalamus (n = 1) and cerebral peduncle (n = 1). CONCLUSIONS: Secondary dystonia may be caused by brain tumors in diverse locations including basal ganglia, cortex and thalamus. It may be the presenting symptom of brain tumor or follow surgical resection combined with ancillary therapy.

Informing the Physical Therapy Management of Congenital Muscular Torticollis Clinical Practice Guideline: A Systematic Review.

PURPOSE: To systematically review current evidence on the physical therapy assessment, intervention, and prognosis of congenital muscular torticollis (CMT) to inform the update to the 2018 CMT Clinical Practice Guideline (CPG). METHODS: Six databases were searched for studies that informed assessment, intervention, and prognosis for physical therapy management of infants with CMT. RESULTS: Fifteen studies were included. Four studies investigated the psychometric properties of new and established assessments. Six studies informed the feasibility and efficacy of first-choice and supplemental interventions including traditional Chinese medicine and neural and visceral manipulation. One qualitative study found that parents of infants with mild and severe CMT had different concerns. Five studies informed prognosis, including factors associated with treatment duration, clinical outcomes, and use of supplemental interventions. CONCLUSION: Newer evidence reaffirms 5 of 17 recommendations of the 2018 CMT CPG and could increase the recommendation strength to strong for neck passive range of motion.

Extraperitoneal Laparoscopic Modified Y-V Plasty for the Treatment of Refractory Bladder Neck Contracture.

Bladder neck contracture (BNC) is a rare, late complication of transurethral resection of the prostate (TURP). Although the endoscopic procedure is the primary treatment for BNC, the recurrence rate remains high. Y-V plasty offers excellent surgical results for those individuals with refractory and recurrent BNC. Traditional open operations usually fail to provide satisfactory exposure to the operating field and lead to greater invasiveness. Interrupted sutures lead to prolonged operative time and increased anastomotic leakage. Laparoscopic modified Y-V plasty is performed through extraperitoneal access to the pelvis, which provides adequate exposure to the surgical view and avoids intra-abdominal injury. After incising the anterior bladder wall neck in a Y-shaped fashion, anastomosis is performed using two absorbable barbed sutures. The mucosa and submucosa layer of the bladder is closed to both sides with consecutive sutures in a V-shape before suturing serosa, and tunica muscularis are sutured to reinforce. The aforementioned procedures reduce leakage from the anastomosis and decrease operative time and patient trauma. Extraperitoneal laparoscopic modified Y-V plasty offers significant advantages over the open approach in terms of post-surgical recovery and invasiveness, making it a feasible and safe surgical option for patients with refractory BNC.

[WU Lian-zhong's experience in treating spasmodic torticollis by Kaiqiao Shunjin method].

Professor WU Lian-zhong's experience in treating spasmodic torticollis by Kaiqiao Shunjin method (resuscitation and regulating muscle) is summarized in this paper. The pathogenesis of spasmodic torticollis is the occluded brain orifices and delirium, qi disorder of meridian tendons, specifically divided into five categories: damp-heat, liver-yang hyperactivity, liver-kidney yin deficiency, deficiency of the governor vessel, excess of the governor vessel. The treatment should be based on the symptoms and the root causes, the symptoms should be the main treatment, and the root cause should be treated based on syndrome differentiation. The main treatment is Kaiqiao Shunjin method (resuscitation and regulating muscle), and to take the chief (five heart acupoints-Shuigou [GV 26], Laogong [PC 8], Yongquan [KI 1]), deputy (Yintang [GV 24+], Shangxing [GV 23] through Baihui [GV 20], Ximen [PC 4]), assistant (Fenglong [ST 40], Lianquan [CV 23], combined with tongue needle prick), envoy (Hanyan [GB 4]) as the basic main acupoints, at the same time cooperate with local acupoints to remove knots and accumulation. Finally, syndrome differentiation is adopted to dredge meridians and disperse knots, regulate the governor vessel, and nourish yin and dispel wind.

Bilateral subthalamic nucleus deep brain stimulation for refractory isolated cervical dystonia.

Subthalamic nucleus (STN) deep brain stimulation (DBS) has been proven to be an alternative target choice for refractory isolated cervical dystonia (CD). However, assessments of its short and long-term safety, efficacy, and sustained effectiveness have been limited to few reports. Here, we evaluated nine consecutive refractory isolated CD patients who underwent bilateral STN DBS and accepted to short and long-term follow-up in this retrospective study. Seven time points were used to see the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) scores (pre-operation [baseline], 1, 3, 6, 12, 24 months post-operation and last follow-up) to assess improvement of dystonic symptoms. The 36-item Short-Form General Health Survey (SF-36) scores obtained at pre-operation and last follow-up to assess the changes in quality of life. All patients tolerated surgery well and acquired observable clinical benefits from STN DBS therapy. All patients achieved a considerable improvement in quality of life at the last follow-up. The hardware-related adverse events can be tolerated and the stimulation-related adverse events can be ameliorated by programming. Our data support the idea that bilateral STN DBS is a safety and effective method for the treatment of refractory isolated CD, with persistent and remarkable improvement in both movement and quality of life.

Vim-Thalamic Deep Brain Stimulation for Cervical Dystonia and Upper-Limb Tremor: Quantification by Markerless-3D Kinematics and Accelerometry.

Background: Deep Brain Stimulation (DBS) for dystonia is usually targeted to the globus pallidus internus (GPi), though stimulation of the ventral-intermediate nucleus of the thalamus (Vim) can be an effective treatment for phasic components of dystonia including tremor. We report on a patient who developed a syndrome of bilateral upper limb postural and action tremor and progressive cervical dystonia with both phasic and tonic components which were responsive to Vim DBS. We characterize and quantify this effect using markerless-3D-kinematics combined with accelerometry. Methods: Stereo videography was used to record our subject in 3D. The DeepBehavior toolbox was applied to obtain timeseries of joint position for kinematic analysis [1]. Accelerometry was performed simultaneously for comparison with prior literature. Results: Bilateral Vim DBS improved both dystonic tremor magnitude and tonic posturing. DBS of the hemisphere contralateral to the direction of dystonic head rotation (left Vim) had greater efficacy. Assessment of tremor magnitude by 3D-kinematics was concordant with accelerometry and was able to quantify tonic dystonic posturing. Discussion: In this case, Vim DBS treated both cervical dystonic tremor and dystonic posturing. Markerless-3D-kinematics should be further studied as a method of quantifying and characterizing tremor and dystonia.

External treatment of herbal medicine with tuina in congenital muscular torticollis: A protocol for systematic review and meta-analysis.

BACKGROUND: This study is the protocol to evaluate the clinical evidence for external treatments using herbal medicine (ETHM) with tuina as a congenital muscular treatment (CMT) in pediatrics. METHODS: Eleven databases will be searched until June 2022, without any language restrictions: four English databases (MEDLINE, Pubmed, EMBASE, and The Cochrane Central Register of Database of Controlled Trials), three Chinese databases (China National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan Fang Database), and four Korean electronic databases (Oriental Medicine Advanced Searching Integrated System, Korean Studies Information Service System, National Digital Science Links, and Research Information Sharing Service). This review will include randomized clinical trials (RCTs) of ETHM with tuina as an intervention versus the same tuina. All published RCTs for any ETHM for CMT will be included. Non-RCTs, RCT protocol, animal studies, case reports, reviews, and surveys will be excluded. The methodological quality assessment will be performed using the Cochrane risk of bias (ROBs). Review Manager version 5.4. will be used for the data synthesis and quantitative analysis. RESULTS AND DISCUSSIONS: The systematic review and meta-analysis will provide evidence for ETHM as a treatment of CMT. The evidence can help clinicians and patients recognize more effective therapeutic and safe inventions. INPLASY REGISTRATION NUMBER: INPLASY202210017.

Optimal deep brain stimulation sites and networks for cervical vs. generalized dystonia.

Dystonia is a debilitating disease with few treatment options. One effective option is deep brain stimulation (DBS) to the internal pallidum. While cervical and generalized forms of isolated dystonia have been targeted with a common approach to the posterior third of the nucleus, large-scale investigations regarding optimal stimulation sites and potential network effects have not been carried out. Here, we retrospectively studied clinical results following DBS for cervical and generalized dystonia in a multicenter cohort of 80 patients. We model DBS electrode placement based on pre- and postoperative imaging and introduce an approach to map optimal stimulation sites to anatomical space. Second, we investigate which tracts account for optimal clinical improvements, when modulated. Third, we investigate distributed stimulation effects on a whole-brain functional connectome level. Our results show marked differences of optimal stimulation sites that map to the somatotopic structure of the internal pallidum. While modulation of the striatopallidofugal axis of the basal ganglia accounted for optimal treatment of cervical dystonia, modulation of pallidothalamic bundles did so in generalized dystonia. Finally, we show a common multisynaptic network substrate for both phenotypes in the form of connectivity to the cerebellum and somatomotor cortex. Our results suggest a brief divergence of optimal stimulation networks for cervical vs. generalized dystonia within the pallidothalamic loop that merge again on a thalamo-cortical level and share a common whole-brain network.

Development of a patient journey map for people living with cervical dystonia.

BACKGROUND: Patient journey maps are increasingly used as a tool that enables healthcare providers to refine their service provision to best meet patient needs. We developed a cervical dystonia patient journey map (CDPJM) that describes the holistic patient experience from pre-diagnosis through to long-term treatment. METHODS: The CDPJM was developed in 2 stages; a patient survey (open questions and multichoice) of 15 patients with CD was conducted to inform the design of the CDPJM, which was then refined and validated by an expert-patient focus group. RESULTS: Qualitative analysis of the patient survey supported five key stages of the patient journey: symptom onset, diagnosis and therapeutic relationship with healthcare professionals, initiation of care for CD, start of CD treatment, and living with treated CD. Following symptom onset, survey respondents described having multiple visits to their family doctor who prescribed strong pain killers and muscle relaxants and referred their patient to up to 10 different specialists for diagnosis. Over half (53.3%) of respondents had received ≥ 1 misdiagnosis. Respondents reported relief at having a diagnosis but a lack of understanding of the prognosis and treatment options; 46.7% said their neurologist did not spend enough time addressing their concerns. Survey respondents reported using a variety of alternative sources of information, including the internet (86.7%), self-help groups (66.7%) and information leaflets provided by health care professionals (60.0%). While botulinum toxin (BoNT) was consistently discussed as the main treatment option, some neurologists also mentioned physiotherapy, counselling, and other complementary approaches. However, patients were often left to seek complementary services themselves. Patients reported a 'rollercoaster' of relief with BoNT treatment with symptoms (and subsequent impact on daily life) returning towards the end of an injection cycle. "When BoNT works well I can return to an almost normal life … when the injections stop working so well, I have to rest more and avoid going to work and experience life restrictions." CONCLUSIONS: We present the first patient journey map for CD that can be used to guide local service mapping and to compare current provision with what patients say they want and need.

Chinese massage (Tuina) combline with paraffin therapy versus tuina or paraffin therapy alone for the treatment of congenital muscular torticollis: A protocol for systematic review and Bayesian network meta-analysis.

BACKGROUND: Current studies in patients with congenital muscular torticollis (CMT) have predominantly focused on the role of tuina or paraffin therapy alone. This systematic review with Bayesian network meta-analysis will be performed to sum up the existing evidence on the effects and safety of tuina plus paraffin therapy for CMT in infants and children. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyzes reporting guidelines will be followed to conduct this study. The electronic databases of PubMed, Cochrane Library, PsycINFO, EMBASE, the Chinese Scientific Journal Database, China National Knowledge Infrastructure, WanFang Data, Taiwan Electronic Periodical Services, and Web of Science will be searched from the inception to November 2021 using the following key terms: "Tuina," "traditional Chinese medicine massage," "paraffin," and "congenital muscular torticollis," for all relevant studies. We impose no language restrictions. We include reports on randomized controlled trials (RCTs) and quasi-RCTs of Tuina combline with paraffin therapy for the treatment of CMT in children and adolescents. We include studies that assessed effective rate, symmetry, improvements of range of motion, muscle length, and sternocleidomastoid tumor thickness, quality of life, and adverse events. The Cochrane Bias Risk Tool, which considers sequence generation, allocation concealment, and blinding and other aspects of bias, will be used to assess the risk of bias in studies. RESULTS: A Bayesian network meta-analysis is an appropriate statistical method to compare all treatment options by statistically simulating the estimated results of a comprehensive trial, and to compare treatments by common and associated comparators. In addition, Bayesian network meta-analysis can produce ranking probabilities of treatments, which may contribute to clinicians' clinical decision-making. REGISTRATION NUMBER: 10.17605/OSF.IO/K5EGN.

Study protocol: multimodal physiotherapy as an add-on treatment to botulinum neurotoxin type A therapy for patients with cervical dystonia: DysPT-multi-a prospective, multicentre, single-blind, randomized, controlled study.

BACKGROUND: Botulinum neurotoxin (BoNT) is currently the best therapeutic option in the treatment for cervical dystonia (CD). Additional treatments like physiotherapy (PT) may even improve the results of the BoNT injection with type A (BoNT-A), but there are no definite recommendations. In the last few years, some studies showed tendencies for PT as an adjuvant therapy to benefit. However, high-quality studies are required. METHODS: This study is a multicentre, randomized, single-blind, controlled trial to demonstrate the effectiveness of a multimodal PT program compared to a nonspecific cupping therapy, additionally to the BoNT-A therapy. Two hundred participants will be assigned into the multimodal PT plus BoNT intervention arm or the BoNT plus cupping arm using randomization. Primary endpoint is the total Score of Toronto Western Spasmodic Rating Scale (TWSTRS). Secondary endpoints are the mobility of the cervical spine (range of motion, ROM), the TWSTRS subscales, and the quality of life (measured by questionnaires: CDQ-24 and SF-36). Patients will be single-blind assessed every 3 months according to their BoNT injection treatment over a period of 9 months. DISCUSSION: The study aims to determine the effectiveness and therefore potential benefit of an additional multimodal physiotherapy for standardized treatment with BoNT-A in patients with CD, towards the BoNT-therapy alone. This largest randomized controlled trial in this field to date is intended to generate missing evidence for therapy guidelines. TRIAL REGISTRATION: The study was registered in the German Clinical Study Register before the start of the patient recruitment ( DRKS00020411 ; date: 21.01.2020).

Effect of physical therapy intervention on thickness and ratio of the sternocleidomastoid muscle and head rotation angle in infants with congenital muscular torticollis: A randomized clinical trial (CONSORT).

BACKGROUND: Early diagnosis as well as treatment is important in management of congenital muscular torticollis (CMT). The purpose of this study was to find an effective physical therapy modality to improve the sternocleidomastoid (SCM) muscle thickness, the ratio of the SCM muscle thickness on the affected side to that on the non-affected side (A/N ratio), and head rotation in infant under 3 months of age diagnosed with CMT. METHODS AND ANALYSIS: A single-blind, randomized clinical trial was conducted. Participants were assigned in one of the 3 study groups through randomization. The treatment was performed 3 times a week for 30 minutes until the head tilt was ≤5 degrees. Group 1 was treated by handling for active or active-assist movement, group 2 was treated with passive stretching, and group 3 was treated with thermotherapy. For general characteristics, a χ2 test and 1-way analysis of variance were used. Intragroup differences were analyzed using a paired t test, and intergroup differences were analyzed using an age-adjusted analysis of covariance. RESULTS: After the intervention, there was no significant difference between groups in terms of SCM thickness on the affected side and A/N ratio (P > .05). Degree of head rotation on the affected side showed significant differences between groups (P < .05), with Group 2 showing significantly better results than group 1 and group 3 (P < .05, both). CONCLUSION: Passive stretching treatment was more effective than other treatments of this study for improvement in degree of head rotation in CMT infants under 3 months of age. TRIAL REGISTRATION: The trial is registered at the Institutional Review Board of Sahmyook University (IRB number, 2-7001793-AB-N-012019103HR) and the Clinical Research Information Service (CRiS; registry number, KCT0004862).

[Summary on WEI Li-fu's experience in clinical treatment of spasmodic torticollis].

The thinking and experience of professor WEI Li-fu in the treatment of spasmodic torticollis under the guidance of ZHU Lian's academic thoughts are introduced. In pathogenesis, spasmodic torticollis is related to the obstruction of yang qi circulation and malnutrition of tendons and vessels. "Promoting yang and benefiting qi" is considered as the main treating principle. In the affected local area, the acupoints are selected from yangming meridians, shaoyang meridians and taiyang meridians of hand and foot. The acupoints of the governor vessel, the he-sea points of the involved yang meridians on the four limbs as well as "four-gate" points are selected as the distal acupoints. During treatment, the "restricting" needling technique invited by ZHU Lian is combined, deqi (qi arrival) is emphasized particularly. Besides, the ironing moxibustion technique is commonly adopted in combination in the affected area.

Neurorehabilitation in dystonia: a holistic perspective.

Rehabilitation for isolated forms of dystonia, such as cervical or focal hand dystonia, is usually targeted towards the affected body part and focuses on sensorimotor control and motor retraining of affected muscles. Recent evidence, has revealed people who live with dystonia experience a range of functional and non-motor deficits that reduce engagement in daily activities and health-related quality of life, which should be addressed with therapeutic interventions. These findings support the need for a holistic approach to the rehabilitation of dystonia, where assessment and treatments involve non-motor signs and symptoms, and not just the dystonic body part. Most studies have investigated Cervical Dystonia, and in this population, it is evident there is reduced postural control and walking speed, high fear of falling and actual falls, visual compensation for the impaired neck posture, and a myriad of non-motor symptoms including pain, fatigue, sleep disorders and anxiety and depression. In other populations of dystonia, there is also emerging evidence of falls and reduced vision-related quality of life, along with the inability to participate in physical activity due to worsening of dystonic symptoms during or after exercise. A holistic approach to dystonia would support the management of a wide range of symptoms and signs, that if properly addressed could meaningfully reduce disability and improve quality of life in people living with dystonia.
