Factors Influencing Triage to Rehabilitation in Functional Movement Disorder.

BACKGROUND: Treatment of functional movement disorder (FMD) should be individualized, yet factors determining rehabilitation engagement have not been evaluated. Subspecialty FMD clinics are uniquely poised to explore factors influencing treatment suitability and triage. OBJECTIVES: To describe our approach and explore factors associated with triage to FMD rehabilitation. METHODS: We conducted a retrospective chart review of 158 consecutive patients with FMD seen for integrated assessment by movement disorders neurology and psychiatry, with the purpose of triage to rehabilitation. Demographic and clinical variables were compared between patients triaged to therapy versus no therapy, and logistic regression was used to explore factors predictive of triage outcome. Change in primary outcome scores were analyzed. RESULTS: Sixty-six patients (42%) were triaged to FMD therapy from July 2019 to December 2021. Patients triaged to therapy were more likely to have a constant movement disorder, gait disorder and/or tremor, hyperarousal, readiness for change, and people pleasing traits. Patients triaged to no therapy demonstrated persistent diagnostic disagreement, an inability to appreciate motor symptom inconsistency, low self-agency, a propensity to dissociate, and cluster B traits. 90% of patients triaged to rehabilitation had improved outcomes. CONCLUSIONS: The ability to "opt-in" to FMD rehabilitation relies on different factors than those relevant to establishing a diagnosis. Unlike many other neurological disorders, a triage and treatment planning step is recommended to identify those likely to meaningfully engage at that time. Holistic assessment through a transdisciplinary lens, and working collaboratively with the patient is essential to prioritize symptoms, determine engagement, and identify treatment targets.

The Benefits of Combining Bobath and Vojta Therapies in Infants with Motor Development Impairment-A Pilot Study.

Background: In infants presenting with motor development impairment, early kinesiotherapeutic interventions aim to normalise the pattern of movements and improve recovery. By applying Bobath and Vojta methods, we aimed to identify a combined approach regarding motor deficit in infants with neurological disabilities. Methods: We designed a prospective interventional study on 108 infants with motor developmental delay and applied Bobath, Vojta, or combined Bobath and Vojta therapy in three equal groups. Results: In the combined Bobath and Vojta group, complete motor recovery was achieved for 50% of the participants, with full recovery after six months, whereas in Bobath- or Vojta-only therapy groups, the total recovery for all participants was achieved at seven months. Regarding infants with muscular hypertonia, Bobath therapy initiation demonstrated complete recovery in 5 months in more than 50% of the cases, while for Vojta this was achieved in only 33.57% of the cases. Conclusions: The comparative evaluation conducted by analysing the data regarding the application of the Bobath and Vojta methods showed that combining these two therapies results in a shorter motor deficit recovery time than if a single therapy is applied. These findings have important implications for the selection of rehabilitation therapies in infants with neurological motor development issues.

Rehabilitative training paired with peripheral stimulation promotes motor recovery after ischemic cerebral stroke.

Spontaneous recovery of ischemic stroke is very limited and often results in the loss of motor and sensory function. Till now, rehabilitative training is the most widely accepted therapy to improve long-term outcome. However, its effectiveness is often suboptimal, largely due to a sharp decline of neuroplasticity in adults. In this study, we hypothesized that a combination of proprioceptive stimulation and rehabilitative training will promote neuroplasticity and functional recovery post injury. To test this hypothesis, we first established a photothrombotic stroke model that lesions the hindlimb sensorimotor cortex. Next, we demonstrated that injecting Cre-dependent AAV-retro viruses into the dorsal column of PV-Cre mice achieves specific and efficient targeting of proprioceptors. With chemogenetics, this method enables chronic activation of proprioceptors. We then assessed effects of combinatorial treatment on motor and sensory functional recovery. Our results showed that pairing proprioceptive stimulation with rehabilitative training significantly promoted skilled motor, but not tactile sensory functional recovery. This further led to significant improvement when compared to rehabilitation training or proprioceptor stimulation alone. Mechanistically, combinatorial treatment promoted cortical layer V neuronal mTOR activity and sprouting of corticospinal axon into the area where proprioceptive afferents terminate in the denervated side of the spinal cord. Serving as a proof of principle, our study thus provided novel insights into the application of combining proprioceptive stimulation and rehabilitative training to improve functional recovery of ischemic stroke and other traumatic brain or spinal cord injuries.

Corticomuscular coupling analysis based on improved LSTM and transfer entropy.

The study of functional corticomuscular coupling can reflect the interaction between the cerebral cortex and muscle tissue, thereby helping to understand how the brain controls muscle tissue and the effect of muscle movement on brain function. This study proposes a detection model of the coupling strength between the cortex and muscles. The detection model uses an adaptive selector to choose the optimal long short-term memory network, uses this network to extract the features of electroencephalography and electromyography, and finally transforms time characteristics into the frequency domain. The transfer entropy is used to represent the interaction intensity of signals in different frequency bands. Using this model, we analyze the coupling relationship between the cortex and muscles in the three movements of wrist flexion, wrist extension, and clench fist, and compare the model with traditional wavelet coherence analysis and deep canonical correlation analysis. The experimental results show that our model can not only express the bidirectional coupling relationship between different frequency bands but also suppress the possible false coupling that traditional methods may detect. Our research shows that the proposed model has great potential in medical rehabilitation, movement decoding, and other fields.

Disrupted Access to Therapies and Impact on Well-Being During the COVID-19 Pandemic for Children With Motor Impairment and Their Caregivers.

OBJECTIVES: The aim of this study was to determine the impact of the COVID-19 pandemic on access to rehabilitation therapies and the impact of changes in therapy access on the physical and mental well-being of children with motor impairment and their caregivers. DESIGN: Caregivers of children younger than 18 yrs with childhood-onset motor impairment (primarily cerebral palsy) completed an anonymous survey through the online platform REDCap between May 5 and July 13, 2020. RESULTS: The survey was completed by 102 participants. Before the pandemic, 92 of 102 children (90%) were receiving one or more therapies; at the time surveyed, 55 children (54%) were receiving any therapies (P < 0.001). More than 40% of the sample reported increased child stress, decreased physical activity, and/or decline in mobility/movement. Participants who reported a decrease in number of therapies at the time surveyed more frequently reported lower satisfaction with treatment delivery (P < 0.001), a decline in child's mobility (P = 0.001), and increased caregiver stress (P = 0.004). Five qualitative themes were identified from open-ended question responses related to therapies and well-being. CONCLUSIONS: Access to pediatric rehabilitation therapies was disrupted during COVID-19. Disrupted access may be related to impact on physical and mental health. With the expansion of telehealth, caregiver and child feedback should be incorporated to optimize benefit.

A First Step Toward the Operationalization of the Learned Non-Use Phenomenon: A Delphi Study.

BACKGROUND: The negative discrepancy between residual functional capacity and reduced use of the contralesional hand, frequently observed after a brain lesion, has been termed Learned Non-Use (LNU) and is thought to depend on the interaction of neuronal mechanisms during recovery and learning-dependent mechanisms. OBJECTIVE: Albeit the LNU phenomenon is generally accepted to exist, currently, no transdisciplinary definition exists. Furthermore, although therapeutic approaches are implemented in clinical practice targeting LNU, no standardized diagnostic routine is described in the available literature. Our objective was to reach consensus regarding a definition as well as synthesize knowledge about the current diagnostic procedures. METHODS: We used a structured group communication following the Delphi method among clinical and scientific experts in the field, knowledge from both, the work with patient populations and with animal models. RESULTS: Consensus was reached regarding a transdisciplinary definition of the LNU phenomenon. Furthermore, the mode and strategy of the diagnostic process, as well as the sources of information and outcome parameters relevant for the clinical decision making, were described with a wide range showing the current lack of a consistent universal diagnostic approach. CONCLUSIONS: The need for the development of a structured diagnostic procedure and its implementation into clinical practice is emphasized. Moreover, it exists a striking gap between the prevailing hypotheses regarding the mechanisms underlying the LNU phenomenon and the actual evidence. Therefore, basic research is needed to bridge between bedside and bench and eventually improve clinical decision making and further development of interventional strategies beyond the field of stroke rehabilitation.

Multidisciplinary inpatient rehabilitation for Functional Movement Disorders: A prospective study with long term follow up.

INTRODUCTION: Functional Movement Disorders (FMDs) are challenging to treat. We assessed the effect of multidisciplinary inpatient rehabilitation, involving motor retraining, psychotherapy and psychotropic medication on FMD patient function and maintenance of improvement after one year. METHODS: FMD patients in a movement disorders clinic were referred for inpatient rehabilitation. Baseline, discharge and one year follow-up measures included: Clinical Global Impression (CGI-severity, CGI-change); Depression and Somatic Symptom Scale (DSSS); Generalized Anxiety Disorder-7 (GAD-7); Patient Health Questionnaire-9 (PHQ-9); Post-traumatic stress disorder check-list for DSM-5 (PCL-5). Outcomes were analyzed with non-parametric models. RESULTS: Seventeen patients completed rehabilitation. Thirteen completed one-year follow-up. Median CGI-severity was "markedly ill." At discharge, movement disorder improved in 93% (median CGI-change = 2, "much improved") as assessed by neurologist and patient. Psychiatrist ratings showed improvement among 86.7%; physiatrist and psychologist ratings were 66.7% and 53.3%, respectively. Symptoms improved on DSSS (Wilcoxon Z = -2.914, p ≤ 0.004); GAD-7 (Z = -3.045, p ≤ 0.002); PHQ-9 (Z = -3.415, p ≤ 0.01) but not PCL-5 (Z = -1.506, p = 0.132). At 1 year, 54% maintained at least minimal improvement by neurologist rating and 77% by patient rating (median CGI-change = 3, "minimally improved"). Improvement was not maintained for DSSS (Wilcoxon Z = -0.385. p = 0.701), GAD-7 (Z = -0.943, p = 0.357) or PHQ-9 (Z = -0.55, p = 0.582). CONCLUSIONS: Multidisciplinary inpatient rehabilitation improved FMD patient function, depression, anxiety and somatic symptoms. One-year follow-up demonstrated minimal sustained improvement and worsening psychopathology, reflecting chronic debility despite initial rehabilitative success.

Balance, Lateropulsion, and Gait Disorders in Subacute Stroke.

OBJECTIVE: To test the hypothesis that impaired body orientation with respect to gravity (lateropulsion) would play a key role in poststroke balance and gait disorders. METHODS: Cohort study of 220 individuals consecutively admitted to a neurorehabilitation ward after a first hemisphere stroke (DOBRAS cohort [Determinants of Balance Recovery After Stroke] 2012-2018, ClinicalTrials.gov: NCT03203109), with clinical data systematically collected at 1 month, then at discharge. Primary outcomes were balance and gait disorders, quantified by the Postural Assessment Scale for Stroke and the modified Fugl-Meyer Gait Assessment, to be explained by all deficits on day 30, including lateropulsion assessed with the Scale for Contraversive Pushing. Statistics comprised linear regression analysis, univariate and multivariate analyses, and receiver operating characteristic curves. RESULTS: Lateropulsion was frequent, especially after right hemisphere stroke (RHS, D30, 48%; discharge 24%), almost always in right-handers. Among all deficits, impaired body orientation (lateropulsion) had the most detrimental effect on balance and gait. After RHS, balance disorders were proportional to lateropulsion severity, which alone explained almost all balance disorders at initial assessment (90%; 95% confidence interval [CI] [86-94], p < 0.001) and at discharge (92%; 95% CI 89-95, p < 0.001) and also the greatest part of gait disorders at initial assessment (66%; 95% CI 56-77, p < 0.001) and at discharge (68%; 95% CI 57-78, p < 0.001). CONCLUSION: Lateropulsion is the primary factor altering poststroke balance and gait at the subacute stage and therefore should be systematically assessed. Poststroke balance and gait rehabilitation should incorporate techniques devoted to misorientation with respect to gravity.

Development and evaluation of a novel music-based therapeutic device for upper extremity movement training: A pre-clinical, single-arm trial.

Restoration of upper limb motor function and patient functional independence are crucial treatment targets in neurological rehabilitation. Growing evidence indicates that music-based intervention is a promising therapeutic approach for the restoration of upper extremity functional abilities in neurologic conditions such as cerebral palsy, stroke, and Parkinson's Disease. In this context, music technology may be particularly useful to increase the availability and accessibility of music-based therapy and assist therapists in the implementation and assessment of targeted therapeutic goals. In the present study, we conducted a pre-clinical, single-arm trial to evaluate a novel music-based therapeutic device (SONATA) for upper limb extremity movement training. The device consists of a graphical user interface generated by a single-board computer displayed on a 32" touchscreen with built-in speakers controlled wirelessly by a computer tablet. The system includes two operational modes that allow users to play musical melodies on a virtual keyboard or draw figures/shapes whereby every action input results in controllable sensory feedback. Four motor tasks involving hand/finger movement were performed with 21 healthy individuals (13 males, aged 26.4 ± 3.5 years) to evaluate the device's operational modes and main features. The results of the functional tests suggest that the device is a reliable system to present pre-defined sequences of audiovisual stimuli and shapes and to record response and movement data. This preliminary study also suggests that the device is feasible and adequate for use with healthy individuals. These findings open new avenues for future clinical research to further investigate the feasibility and usability of the SONATA as a tool for upper extremity motor function training in neurological rehabilitation. Directions for future clinical research are discussed.

Performing Arts Medicine.

Performing artists are a unique subset of athletes. With the highly repetitive nature of performance training, emphasis on proper technique, ergonomics, and preventive cross-training is vital, as many injuries are due to overuse or poor technique. There are novel medical concerns in performers, including ENT problems, mental health concerns and substance use risks. While music is central to performances, it is also a treatment modality to address cognitive, sensory, and motor dysfunctions in certain neurological conditions. Due to this wide array of issues, it is imperative to understand the specific needs and risks of performers to provide optimal medical care.

Neural activity in functional movement disorders after inpatient rehabilitation.

Functional movement disorders (FMD) are a common source of disability in neurology.While treatment of FMD can reduce motor severity and disability, the neural mechanisms implicated in such a response remain unclear. We aimed to investigate neural changes in patients with FMD after a one-week multidisciplinary motor retraining (MoRe) treatment program. Fourteen FMD patients completed an emotional Go/No-Go fMRI task before and after MoRe treatment. Standardized pre- and post-treatment videos were rated for motor severity by a blinded reviewer using the psychogenic movement disorder rating scale (PMDRS). PMDRS scores before and after treatment were used for whole-brain regression. PMDRS scores were significantly reduced after MoRe treatment. Worse severity prior to treatment was associated with greater primary motor cortex (M1) activation at baseline and a larger response to treatment. Globally, increased connectivity between bilateral amygdala and premotor regions was observed following treatment. Lower post-treatment PMDRS scores were associated with increased connectivity between amygdala and ventromedial prefrontal cortex, whereas higher post-treatment PMDRS scores (and poorer treatment response) were associated with increased connectivity between amygdala and M1. Motor retraining in FMD may reorganize activity and connectivity in emotion processing and motor planning networks, with shifts in amygdala connectivity from posterior to frontal/prefrontal regions.

[Efficiency of acupuncture and relaxation sessions in improvement of psychophysical state]. / The efficiency of acupuncture and relaxation sessions in improvement of psychophysical state (Éffektivnost' akupunktury i relaksatsii v korrektsii psikhofizicheskogo sostoianiia).

A study of the changes in psychophysical function of the human body before and after relaxation sessions and acupuncture application has been conducted. The impact of relaxation sessions on psychophysical performance was studied on a group of university students and postgraduates aged between 18 and 30 years old; the impact of an acupuncture session course - on a group of subjects of a broad age range between 14 and 72, as they underwent rehabilitation therapy for their supportive locomotive apparatus disorders. The recording techniques used included electroencephalography (EEG), psychomotor reaction recording, minute-long time span accuracy reproduction; TST technique (Tactile Solar Test) of meridian and microsystem examination The results of this study suggest that relaxation sessions contribute to the enhancement of neurodynamical performance and mental activity efficiency. After the acupuncture therapy, relaxation effect, and restored tactile sensation on the meridians and microsystems was noted. A conclusion has been made that relaxation sessions and acupuncture may be used to improve psychophysical function.

Games Applied to Children with Motor Impairment using the Myo Wearable Device.

The characteristic of immersion, involvement and motivation have made serious games an important tool to be used in the medical field. However, there are people that, having some sort of physical disability, are not able to, or do not feel motivated to play. This work presents a strategy to support human- computer interactions for children with a disability in their upper limbs through a wearable device, with the objective of improving access to digital games for the target audience. For the development of this work, the wearable device Myo was used to control a puzzle game as a means of providing the interaction between the individual and the game. In this context, the game is controlled with the movement of the user's upper limb that presents the disability, through the Myo device. For the validation of this research, the game developed was made available for individuals presenting a disability in the upper limbs, from an age range between five and fifteen years old, of the Association of Assistance to the Disabled Child (AACD). Soon, it was noticed that the participants of the research soon could play while utilizing the deficient limb with Myo's support and felt more motivated to play. On the long run, it is expected to contribute to the motivation of patients through technological innovation, so that the process of body consciousness is made more interactive.

Effects of hybrid-functional electrical stimulation (FES) rowing whole-body exercise on neurologic improvement in subacute spinal cord injury: secondary outcomes analysis of a randomized controlled trial.

STUDY DESIGN: Secondary outcome measures analysis of a randomized, controlled study. OBJECTIVE: To assess the effects of hybrid-functional electrical stimulation (FES) rowing on motor and sensory recovery in individuals with spinal cord injury (SCI) 6-18 months post injury. SETTING: Outpatient rehabilitation network. METHODS: 25 participants 6-12 months after SCI were randomly assigned to hybrid-FES rowing (n = 10) or standard of care (n = 15) groups. The hybrid-FES rowing group completed 6 months of rowing scheduled 3 times per week for 26 weeks at an exercise intensity of 70-85% of maximal heart rate. The standard of care group either participated in an arm ergometer exercise program (n = 6) or a waitlist without an explicit exercise program (n = 9). Changes in motor score and combined sensory score of the International Standards for Neurological Classification of SCI (ISNCSCI) were analyzed. RESULTS: Both groups demonstrated increases in motor and combined sensory scores, but no significant differences were noted between intervention groups (motor difference mean ↑1.3 (95% CI, -1.9 to 4.4), combined sensory difference mean ↓10 (-30 to 18)). There was an average of 63% adherence to the hybrid-FES rowing protocol, with no significant correlation in changes in motor or combined sensory score in the hybrid-FES rowing group with total distance or time rowed. CONCLUSIONS: No significant effects to neurologic improvement were found with hybrid-FES rowing when compared with standard of care interventions in individuals with SCI 6-18 months post injury.

Assessment of movement coordination strategies to inform health of movement and guide retraining interventions.

INTRODUCTION: Exploring characteristics of human movement has long been the focus of clinicians and researchers. Changes in movement coordination strategies have been identified in the presence of pain highlighting the need for assessment in clinical practice. A major development in the understanding of movement related disorders is recognition of individual differences in presentation and consequently the need to tailor interventions based on assessment. PURPOSE: The purpose of this masterclass is to build a rationale for the clinical assessment of movement coordination strategies, exploring loss of movement choices, coordination variability, and to present a clinical framework for individualised management, including the use of cognitive movement control tests and retraining interventions. An approach for the qualitative rating of movement coordination strategies is presented. A compromised movement system may be one characterised by a lack of ability to access motor abundance and display choice in the use of movement coordination strategies. The identification of lost movement choices revealed during the assessment of movement coordination strategies is proposed as a marker of movement health. IMPLICATIONS FOR PRACTICE: The health of the movement system may be informed by the ability to display choice in movement coordination strategies. There is evidence that restoring these choices has clinical utility and an influence on pain and improved function. This approach seeks to provide individuals with more flexible problem solving, enabled through a movement system that is robust to each unique challenge of function. This assessment framework sits within a bigger clinical reasoning picture for sustained quality of life.

Clinically Integrated Physical Therapist Practice in Cancer Care: A New Comprehensive Approach.

Best practice recommendations in cancer care increasingly call for integrated rehabilitation services to address physical impairments and disability. These recommendations have languished primarily due to a lack of pragmatic, generalizable intervention models. This perspective paper proposes a clinically integrated physical therapist (CI-PT) model that enables flexible and scalable services for screening, triage, and intervention addressing functional mobility. The model is based on (1) a CI-PT embedded in cancer care provider clinics, and (2) rehabilitation across the care continuum determined by the patient's level of functional mobility. The CI-PT model includes regular screening of functional mobility in provider clinics via a patient-reported mobility measure-the Activity Measure for Post-Acute Care, a brief physical therapy evaluation tailored to the specific functional needs of the individual-and a tailored, skilled physical therapist intervention based on functional level. The CI-PT model provides a pragmatic, barrier-free, patient-centric, data-driven approach to integrating rehabilitation as part of standard care for survivors of cancer. The model standardizes CI-PT practice and may be sufficiently agile to provide targeted interventions in widely varying cancer settings and populations. Therefore, it may be ideal for wide implementation among outpatient oncological settings. Implementation of this model requires a shared approach to care that includes physical therapists, rehabilitation administrators, cancer care providers, and cancer center administrators.

Developing a revised definition of the Bobath concept: Phase three.

OBJECTIVE: To develop a revised definition of the Bobath concept that incorporates the perspectives of members of the International Bobath Instructors Training Association (IBITA). METHODS: A three-phase consensus building design utilizing (i) focus groups; (ii) survey methods; and, (iii) real-time Delphi. This paper presents the findings from the real-time Delphi, an iterative process to collect and synthesize expert opinions anonymously, provide controlled feedback, with the overall goal of achieving consensus. RESULTS: One hundred and twenty-one IBITA members participated in the real-time Delphi. Over three Delphi Rounds, consensus was reached on six overarching conceptual statements and 11 statements representing unique aspects of Bobath clinical practice. One statement that aimed to describe the Bobath clinical term of "placing" was eliminated in Round One due to participant reservations that a text description was insufficient for this term. Seven statements underwent minor wording revisions in Round Two and Three to improve sentence clarity. CONCLUSION: Using the real-time Delphi, we were successful in gaining consensus in an expert group on a series of statements on which a revised definition of the Bobath concept could be based.
