The Management of Stroke Rehabilitation: A Synopsis of the 2019 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline.

Description: In June 2019, the U.S. Department of Veterans Affairs (VA) and U.S. Department of Defense (DoD) approved an update of the joint clinical practice guideline for rehabilitation after stroke. This synopsis summarizes the key recommendations from this guideline. Methods: In February 2018, the VA/DoD Evidence-Based Practice Work Group convened a joint VA/DoD guideline development effort that included clinical stakeholders and stroke survivors and conformed to the National Academy of Medicine (formerly the Institute of Medicine) tenets for trustworthy clinical practice guidelines. The guideline panel identified key questions, systematically searched and evaluated the literature, and developed 2 algorithms and 42 key recommendations using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. Stroke survivors and their family members were invited to share their perspectives to further inform guideline development. Recommendations: The guideline recommendations provide evidence-based guidance for the rehabilitation care of patients after stroke. The recommendations are applicable to health care providers in both primary care and rehabilitation. Key features of the guideline are recommendations in 6 areas: timing and approach; motor therapy; dysphagia; cognitive, speech, and sensory therapy; mental health therapy; and other functions, such as returning to work and driving.

Nonpharmacological rehabilitation interventions for motor and cognitive outcomes following pediatric stroke: a systematic review.

The aim of this review was to evaluate the evidence for nonpharmacological rehabilitation interventions for motor and cognitive impairment following pediatric stroke. A literature search was conducted using multiple scientific databases. Studies were included if (1) the study population was > 50% pediatric (< 18 years) stroke, (2) a diagnosis of stroke was explicitly stated, (3) there were ≥ 3 pediatric stroke participants included in the study sample, and (4) motor or cognitive outcome measures were used to assess effect of treatment. Levels of evidence were assigned to each study to determine the strength of the evidence for each intervention. A total of 18 articles met inclusion criteria. Most studies (N = 14) examined rehabilitation of the upper limb, with constraint-induced movement therapy (CIMT) as the most common intervention. Overall, the evidence supports the use of CIMT, forced use therapy, repetitive transcranial magnetic stimulation, functional electrical stimulation, and robotics, but suggests no beneficial effect of transcranial direct current stimulation. Very few studies assessed interventions for the lower limb (N = 1) or cognitive impairment (N = 3).Conclusion: Effective rehabilitation approaches are important for optimizing outcomes in children who have had a stroke. Although the number of published clinical trials has increased in recent years, little evidence-based guidance exists for this clinical population. What is Known: • Pediatric stroke is a significant cause of disability in children that is often associated with long-term motor and cognitive sequelae. • There is a need to establish a knowledge base regarding available evidence-based rehabilitation therapies for this clinical population. What is New: • Most studies examining interventions for motor function focus on upper limb rehabilitation, whereas few studies have investigated interventions for improving lower limb or cognitive impairment. • An important gap exists regarding evidence-based rehabilitative treatment approaches for pediatric stroke.

Does acupuncture ameliorate motor impairment after stroke? An assessment using the CatWalk gait system.

The effect of acupuncture on gait deficits after stroke is uncertain. This animal study was designed to determine whether acupuncture improves gait impairment following experimentally induced ischemic stroke. Ischemic stroke was induced by permanent middle cerebral artery occlusion (MCAO) in rats. After 7 days' of acupuncture treatment, assessment of gait changes using the CatWalk automated gait analysis system was performed. Comparison of the CatWalk gait parameters among the groups showed that gait function was impaired after ischemic stroke and acupuncture treatment was effective in improving a variety of gait parameters including intensity, stance and swing time, swing speed and stride length at postoperative day 8. This study demonstrates a beneficial effect of acupuncture on gait impairment in rats following ischemic stroke. Further studies aimed to investigate the effects of acupuncture at different stages during stroke using the CatWalk system are required.

Thai Elephant-Assisted Therapy Programme in Children with Down Syndrome.

The objectives of this study were to examine the effects of the Thai Elephant-Assisted Therapy Programme for children with Down syndrome (DS) (TETP-D) on balance, postural control and visual motor integration (VMI). A quasi-experimental design with blind control was used. Sixteen children with DS from grades 1 to 6, in a Thailand, public school were recruited for this study. The participants were divided voluntarily into two groups: control and experimental. These both groups received regular school activities, but the experimental group had added treatment, which consisted of TETP-D twice a week for 2 months. The balance subtest of the Bruininks-Oseretsky Test of Motor Proficiency 2, the postural control record form and Beery VMI were applied as outcome measure 1 week before and after the TETP-D. The results showed no significant difference in balance or postural control. However, a significant difference of VMI was shown between the two groups (z = 13.5, p = .04). Children with DS benefited from the TETP-D as it improved their VMI. The TETP-D could improve balance and postural control if provided within a suitable frequency and duration. Further research is needed to test this hypothesis. The limitations of this study are the significant differences in some aspects of the groups at pre-test such as gender and supine flexion of postural control.

Gross motor deficits in children prenatally exposed to alcohol: a meta-analysis.

BACKGROUND AND OBJECTIVES: Gross motor (GM) deficits are often reported in children with prenatal alcohol exposure (PAE), but their prevalence and the domains affected are not clear. The objective of this review was to characterize GM impairment in children with a diagnosis of fetal alcohol spectrum disorder (FASD) or "moderate" to "heavy" maternal alcohol intake. METHODS: A systematic review with meta-analysis was conducted. Medline, Embase, Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, PEDro, and Google Scholar databases were searched. Published observational studies including children aged 0 to ≤18 years with (1) an FASD diagnosis or moderate to heavy PAE, or a mother with confirmed alcohol dependency or binge drinking during pregnancy, and (2) GM outcomes obtained by using a standardized assessment tool. Data were extracted regarding participants, exposure, diagnosis, and outcomes by using a standardized protocol. Methodological quality was evaluated by using Strengthening the Reporting of Observational Studies in Epidemiology guidelines. RESULTS: The search recovered 2881 articles of which 14 met the systematic review inclusion criteria. The subjects' mean age ranged from 3 days to 13 years. Study limitations included failure to report cutoffs for impairment, nonstandardized reporting of PAE, and small sample sizes. The meta-analysis pooled results (n = 10) revealed a significant association between a diagnosis of FASD or moderate to heavy PAE and GM impairment (odds ratio: 2.9; 95% confidence interval: 2.1-4.0). GM deficits were found in balance, coordination, and ball skills. There was insufficient data to determine prevalence. CONCLUSIONS: The significant results suggest evaluation of GM proficiency should be a standard component of multidisciplinary FASD diagnostic services.

Activation of peripheral KCNQ channels attenuates inflammatory pain.

BACKGROUND: Refractory chronic pain dramatically reduces the quality of life of patients. Existing drugs cannot fully achieve effective chronic pain control because of their lower efficacy and/or accompanying side effects. Voltage-gated potassium channels (KCNQ) openers have demonstrated their analgesic effect in preclinical and clinical studies, and are thus considered to be a potential therapeutic target as analgesics. However, these drugs exhibit a narrow therapeutic window due to their imposed central nerve system (CNS) side effects. To clarify the analgesic effect by peripheral KCNQ channel activation, we investigated whether the analgesic effect of the KCNQ channel opener, retigabine, is inhibited by intracerebroventricular (i.c.v.) administration of the KCNQ channel blocker, 10, 10-bis (4-Pyridinylmethyl)-9(10H) -anthracenone dihydrochloride (XE-991) in rats. RESULTS: Oral administration (p.o.) of retigabine showed an anticonvulsant effect on maximal electronic seizures and an analgesic effect on complete Freund's adjuvant-induced thermal hyperalgesia. However, impaired motor coordination and reduced exploratory behavior were also observed at the analgesic doses of retigabine. Administration (i.c.v.) of XE-991 reversed the retigabine-induced anticonvulsant effect, impaired motor coordination and reduced exploratory behavior but not the analgesic effect. Moreover, intraplantar administration of retigabine or an additional KCNQ channel opener, N-(6-Chloro-pyridin-3-yl)-3,4-difluoro-benzamide (ICA-27243), inhibited formalin-induced nociceptive behavior. CONCLUSIONS: Our findings suggest that the peripheral sensory neuron is the main target for KCNQ channel openers to induce analgesia. Therefore, peripheral KCNQ channel openers that do not penetrate the CNS may be suitable analgesic drugs as they would prevent CNS side effects.

Docosahexaenoic acid status at 9 months is inversely associated with communicative skills in 3-year-old girls.

The objective of the present observational study was to investigate if the docosahexaenoic acid (DHA) status assessed in infant erythrocytes (RBC) at 9 months was associated with the age when the infants reach developmental milestones and their psychomotor function at 3 years of age. Three hundred eleven healthy Danish children were followed from 9 months to 3 years of age (the SKOT cohort). RBC fatty acid composition was analysed by gas chromatography in 272 of the children. Milestone age was collected by questionnaires at 9 and 18 months and psychomotor development at 3 years of age was assessed by the parents using third edition of the Ages and Stages Questionnaire (ASQ-3). RBC DHA levels ranged from 2.2% to 12.6% of the RBC fatty acids. The age of reaching milestones correlated with psychomotor development, particularly with gross motor function at 3 years. An association between milestones and later personal and social skills was also observed, but only for girls. In girls, RBC-DHA was found to be inversely correlated with communication at 3 years of age (odds ratio = 0.69, 95% confidence interval: 0.56-0.86, P = 0.001), but no other associations with psychomotor development or milestones were found. The results from study indicate that DHA status at 9 months may not have a pronounced beneficial effect on psychomotor development in early childhood and that communicative skills at 3 years of age may even be inversely associated with early RBC-DHA levels in girls.

Stroke rehabilitation using noninvasive cortical stimulation: motor deficit.

Noninvasive cortical stimulation (NICS) has been used during the acute, postacute and chronic poststroke phases to improve motor recovery in stroke patients having upper- and/or lower-limb paresis. This paper reviews the rationale for using the different NICS modalities to promote motor stroke rehabilitation. The changes in cortical excitability after stroke and the possible mechanisms of action of cortical stimulation in this context are outlined. A number of open and placebo-controlled trials have investigated the clinical effect of repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) of the primary motor cortex in patients with motor stroke. These studies attempted to improve motor performance by increasing cortical excitability in the stroke-affected hemisphere (via high-frequency rTMS or anodal tDCS) or by decreasing cortical excitability in the contralateral hemisphere (via low-frequency rTMS or cathodal tDCS). The goal of these studies was to reduce the inhibition exerted by the unaffected hemisphere on the affected hemisphere and to then restore a normal balance of interhemispheric inhibition. All these NICS techniques administered alone or in combination with various methods of neurorehabilitation were found to be safe and equally effective at the short term on various aspects of poststroke motor abilities. However, the long-term effect of NICS on motor stroke needs to be further evaluated before considering the use of such a technique in the daily routine management of stroke.

Prospective trial of equine-assisted activities in autism spectrum disorder.

BACKGROUND: Anecdotal reports and some studies suggest that equine-assisted activities may be beneficial in autism spectrum disorders (ASD). OBJECTIVE: To examine the effects ofequine-assisted activities on overall severity of autism symptoms using the Childhood Autism Rating Scale (CARS) and the quality ofparent-child interactions using the Timberlawn Parent-Child Interaction Scale. In addition, this study examined changes in sensory processing, quality of life, and parental treatment satisfaction. DESIGN AND PARTICIPANTS: Children with ASD were evaluated at four time points: (1) before beginning a 3-to-6 month waiting period, (2) before starting the riding treatment, and (3) after 3 months and (4) 6 months of riding. Twenty-four participants completed the waiting list period and began the riding program, and 20 participants completed the entire 6 months of riding. Pretreatment was compared to posttreatment with each child acting as his or her own control. RESULTS: A reduction in the severity of autism symptoms occurred with the therapeutic riding treatment. There was no change in CARS scores during the pretreatment baseline period; however, there was a significant decrease after treatment at 3 months and 6 months of riding. The Timberlawn Parent-Child Interaction Scale showed a significant improvement in Mood and Tone at 3 months and 6 months of riding and a marginal improvement in the reduction of Negative Regard at 6 months of riding. The parent-rated quality of life measure showed improvement, including the pretreatment waiting period. All of the ratings in the Treatment Satisfaction Survey were between good and very good. CONCLUSION: These results suggest that children with ASD benefit from equine-assisted activities.

The effectiveness of simulated developmental horse-riding program in children with autism.

This study investigated the effectiveness of a 20-week Simulated Developmental Horse-Riding Program (SDHRP) by using an innovative exercise equipment (Joba) on the motor proficiency and sensory integrative functions in 60 children with autism (age: 6 years, 5 months to 8 years, 9 months). In the first phase of 20 weeks, 30 children received the SDHRP in addition to their regular occupational therapy while another 30 children received regular occupational therapy only. The arrangement was reversed in the second phase of another 20 weeks. Children with autism in this study showed improved motor proficiency and sensory integrative functions after 20-week SDHRP (p < .01). In addition, the therapeutic effect appeared to be sustained for at least 24 weeks (6 months).

Cerebral palsy: classification, diagnosis and challenges of care.

This article aims to build capacity between nursing and allied healthcare practitioner staff in highlighting the unique challenges that caring for people with cerebral palsy (CP) brings. It gives an insight into how CP is classified and diagnosed, and briefly outlines issues of political correctness in labelling people with this condition. It covers the complexities of brain development in people with CP, with consideration of the key aetiological contributors to the incidence of the condition. A straightforward approach to unravelling the classification of movement disorders in CP is adopted. It concludes that a multidisciplinary approach to the management of CP, with the nurse at the centre of this holistic approach to patient care, is pivotal to future healthcare provision.

Estado actual del tratamiento con oxígeno hiperbárico de las enfermedades del aparato locomotor en medicina del deporte / Hyperbaric oxygen treatment of musculoskeletal disorders on the sports medicine. State of the art

La oxigenoterapia hiperbárica es una modalidad terapéutica que se fundamenta en la obtención de presiones parciales de oxígeno elevadas, al respirar oxígeno puro, en el interior de una cámara hiperbárica a una presión superior a la atmosférica. Se trata de un tratamiento farmacológico cuyo margen de aplicación está determinado por la presión máxima alcanzada, la duración de la inhalación y la frecuencia y el número total de exposiciones. Sus indicaciones están clasificadas según su utilidad en preferentes, complementarias o experimentales. Desde ciertos ámbitos privados se ha propuesto este tratamiento como útil en la mejora de enfermedades que, desde el punto de vista de la medicina hiperbárica, se clasificarían como experimentales o en el mejor de los casos como coadyuvantes. Eso ocurre en ciertas enfermedades agudas o crónicas que acontecen en el aparato locomotor y que evalúan diversos especialistas, internistas, reumatólogos, traumatólogos o médicos del deporte. En la presente revisión se desarrollan someramente las indicaciones de la oxigenoterapia hiperbárica, y se da una visión actualizada de su aplicación experimental sobre la evolución de la lesión muscular y el rendimiento físico. Por último, se ofrecen unas consideraciones respecto a lo mínimo que debe requerirse en caso de apoyarse en este tratamiento para mejorar el resultado de la orientación terapéutica que indica el especialista (AU)

Hyperbaric oxygen therapy (OHB) is a therapeutic modality based on the properties of partial pressure of oxygen, when breathing pure oxygen under hyperbaric conditions in a chamber designed for that purpose. Its indications in medicine are considered as primary, complementary or experimental depending on the evidence based effects. From different sectors of medicine, OHB has been recently proposed as a new tool for other pathologies, primarily in musculoskeletal disorders. In this paper, the state of the art of the influence from experimental studies is reviewed. Some considerations based on these studies are hypothesized as the minimum required to obtain good results when this therapy is decided to be used as co adjuvant to standard treatment (AU)

Sensory motor and functional skills of dizygotic twins: one with Smith-Magenis syndrome and a twin control.

Smith-Magenis syndrome (SMS), the result of an interstitial deletion within chromosome 17p11.2, is a disorder that may include minor dysmorphic features, brachydactyly, short stature, hypotonia, speech delays, cognitive deficits, signs of peripheral neuropathy, scoliosis, and neurobehavioral problems including sleep disturbances and maladaptive repetitive and self-injurious behaviors. Physical and occupational therapists provide services for children who have the syndrome, whose genetic disorder is frequently not identified or diagnosed before 1 year of age. A comprehensive physical and occupational therapy evaluation was completed in nonidentical twins with one having SMS, using the Sensory Profile; Brief Assessment of Motor Function (BAMF); Peabody Developmental Motor Scales, Second Edition (PDMS-2); and Pediatric Evaluation of Disability Inventory (PEDI). This provides a framework for conducting assessments to enhance early detection and interdisciplinary management with this specialized population.

Complex traditional Chinese medicine for poststroke motor dysfunction: a systematic review.

BACKGROUND AND PURPOSE: For its current dimensions, stroke represents the world's primary health challenge. In China stroke is the second most common cause of death. Traditional Chinese Medicine (TCM) has for many centuries been used, and it is still widely used today in countries of south and east Asia for the treatment of people with stroke. The objective of this systematic review was to evaluate whether complex Traditional Chinese Medicine (cTCM) improves poststroke motor recovery. In particular, we defined cTCM as intervention that included at least acupuncture and Chinese herbal medicine. METHODS: An extensive search including PubMed, EMBASE, CBM, and the Cochrane Library was performed up to December 2007. Randomized clinical trials (RCTs) about cTCM for motor dysfunction of poststroke were searched irrespective of any language. The quality of each trial was assessed according to the Cochrane Reviewers' Handbook 4.2.6. RESULTS: After selection of 11 234 articles, 34 RCTs and quasi-RCTs were included. All these trials were conducted in China and published on Chinese journals. All trials but one reported results in favor of cTCM treatments suggesting a strong publication bias. Because of the significant clinical and methodological heterogeneity, no meta-analysis was performed and thus no cumulative result was obtained pooling data of RCTs. CONCLUSIONS: What appears from this systematic review is that scant data are available to evaluate efficacy of cTCM for poststroke motor dysfunction. Most of the primary studies available for this review were inadequately designed trials characterized by unknown dropout rates and definitional vagueness in outcomes measures. None of the studies approached important end points like death, survival times, rate of dependency, reduction in length of stay in hospital, etc. The key to lead to evidence-based practices is establishing a consensus on standardized relevant outcome measures and then designing and conducting appropriate RCTs that adopt those standards.

Running posture and step length changes immediately after chiropractic treatment in a patient with xeroderma pigmentosum.

OBJECTIVE: This case study reports on selected measures of locomotion (running) in a 5-year-old patient with xeroderma pigmentosum after chiropractic care. CLINICAL FEATURE: A 5-year-old female patient (16.4 kg, 99.1 cm) with xeroderma pigmentosum (type A) volunteered to participate in the experiment with the consent of her parents. The patient had well-documented signs of delayed fine motor (eg, difficulty with writing, coloring, cutting) and gross motor control (eg, balance and coordination dysfunction and falling while running), and delayed speech. INTERVENTION AND OUTCOMES: Trunk forward lean angles, step lengths, and hip horizontal translations were assessed by video as the participant ran as fast as possible down a laboratory runway. After chiropractic manipulation (adjustments), the patient reduced the trunk forward lean angle to become more vertical (P = .000). In addition, the patient experienced an increase in step length (P = .031). No significant change in lateral translation was observed after the intervention. CONCLUSION: For this patient with xeroderma pigmentosum, chiropractic manipulation (adjustments) resulted in immediate changes in running performance. Further investigation is needed to examine the effect of chiropractic on locomotion in both symptomatic and asymptomatic patients.

Motor cortical stimulation promotes synaptic plasticity and behavioral improvements following sensorimotor cortex lesions.

Cortical stimulation (CS) as a means to modulate regional activity and excitability in cortex is emerging as a promising approach for facilitating rehabilitative interventions after brain damage, including stroke. In this study, we investigated whether CS-induced functional improvements are linked with synaptic plasticity in peri-infarct cortex and vary with the severity of impairments. Adult rats that were proficient in skilled reaching received subtotal unilateral ischemic sensorimotor cortex (SMC) lesions and implantation of chronic epidural electrodes over remaining motor cortex. Based on the initial magnitude of reaching deficits, rats were divided into severely and moderately impaired subgroups. Beginning two weeks post-surgery, rats received 100 Hz cathodal CS at 50% of movement thresholds or no-stimulation control procedures (NoCS) during 18 days of rehabilitative training on a reaching task. Stereological electron microscopy methods were used to quantify axodendritic synapse subtypes in motor cortical layer V underlying the electrode. In moderately, but not severely impaired rats, CS significantly enhanced recovery of reaching success. Sensitive movement analyses revealed that CS partially normalized reaching movements in both impairment subgroups compared to NoCS. Additionally, both CS subgroups had significantly greater density of axodendritic synapses and moderately impaired CS rats had increases in presumed efficacious synapse subtypes (perforated and multiple synapses) in stimulated cortex compared to NoCS. Synaptic density was positively correlated with post-rehabilitation reaching success. In addition to providing further support that CS can promote functional recovery, these findings suggest that CS-induced functional improvements may be mediated by synaptic structural plasticity in stimulated cortex.

Virtual reality environments for post-stroke arm rehabilitation.

INTRODUCTION: Optimal practice and feedback elements are essential requirements for maximal motor recovery in patients with motor deficits due to central nervous system lesions. METHODS: A virtual environment (VE) was created that incorporates practice and feedback elements necessary for maximal motor recovery. It permits varied and challenging practice in a motivating environment that provides salient feedback. RESULTS: The VE gives the user knowledge of results feedback about motor behavior and knowledge of performance feedback about the quality of pointing movements made in a virtual elevator. Movement distances are related to length of body segments. CONCLUSION: We describe an immersive and interactive experimental protocol developed in a virtual reality environment using the CAREN system. The VE can be used as a training environment for the upper limb in patients with motor impairments.

Nutritional megaloblastic anemia in young Turkish children is associated with vitamin B-12 deficiency and psychomotor retardation.

We aimed to investigate the presence of psychomotor retardation, physical and laboratory examination in infants with megaloblastic anemia. Inclusion criteria for the study were; age 9 to 36 months, refusal of food except for breast and cow milk, loss of appetite, developmental delay, significant pallor, and hypersegmentation neutrophils in the peripheral blood smear. A total of 33 children fulfilling the inclusion criteria were enrolled among 3368 patients attending Pediatric Outpatient Clinics of sirnak-Cizre State Hospital between January 25, 2004 and May 5, 2004. Mean age was 16.4 months. Thirty-two patients had Vitamin B12 deficiency, 1 patient had folate deficiency, and 10 patients had combined vitamin B12 and folate deficiency. Statistically, a positive significant relationship was detected between serum vitamin B12 levels and mean corpuscular volume (P = 0.001, r = 0.56), and between vitamin B12 levels and hemoglobin (P = 0.004, r = 0.49). We believe that preventative measures such as fortification of flour with vitamin B12, nutritional support with vitamin B12 for the mother during pregnancy and nursing, provision of adequate primary preventive health services, and starting complementary food after 6 months of age are important determinants for preventing megaloblastic anemia.

Subthalamic nucleus stimulation in advanced Parkinson's disease: blinded assessments at one year follow up.

OBJECTIVE: To measure the effect of deep brain stimulation (DBS) of the subthalamic nucleus in patients with advanced Parkinson's disease. DESIGN: Open label follow up using blinded ratings of videotaped neurological examinations. PATIENTS: 30 patients with advanced Parkinson's disease (19 male, 11 female; mean age 58.8 years; mean disease duration 12.8 years), complicated by intractable wearing off motor fluctuations and dopaminergic dyskinesias. MAIN OUTCOME MEASURES: Unified Parkinson's disease rating scale (UPDRS), part III (motor), score at one year, from blinded reviews of videotaped neurological examinations. Secondary outcomes included the other UPDRS subscales, Hoehn and Yahr scale, activities of daily living (ADL) scale, mini-mental state examination (MMSE), estimates of motor fluctuations and dyskinesia severity, drug intake, and patient satisfaction questionnaire. RESULTS: Subthalamic nucleus stimulation was associated with a 29.5% reduction in motor scores at one year (p<0.0001). The only important predictors of improvement in UPDRS part III motor scores were the baseline response to dopaminergic drugs (p = 0.015) and the presence of tremor (p = 0.027). Hoehn and Yahr scores and ADL scores in the "on" and "off" states did not change, nor did the mean MMSE score. Weight gain occurred in the year after surgery, from (mean) 75.8 kg to 78.5 kg (p = 0.028). Duration of daily wearing off episodes was reduced by 69%. Dyskinesia severity was reduced by 60%. Drug requirements (in levodopa equivalents) declined by 30%. CONCLUSIONS: The 30% improvement in UPDRS motor scores was a more modest result than previously reported. DBS did not improve functional capacity independent of drug use. Its chief benefits were reduction in wearing off duration and dyskinesia severity.

Motor recovery strategies after stroke.

Impaired motor function after stroke is a major cause of disability in young stroke survivors. The plasticity of the adult human brain provides opportunities to enhance traditional rehabilitation programs for these individuals. Younger stroke patients appear to have a greater ability to recover from stroke and are likely to benefit substantially from treatments that facilitate plasticity-mediated recovery. The use of new exercise treatments, such as constraint-induced movement therapy, robot-aided rehabilitation, and partial body weight supported treadmill training are being studied intensively and are likely to ultimately be incorporated into standard poststroke rehabilitation. Medications to enhance recovery, growth factors, and stem cells will also be components of rehabilitation for the young stroke survivor in the foreseeable future.
