Effects of photobiomodulation on pain, lactate and muscle performance (ROM, torque, and EMG parameters) of paretic upper limb in patients with post-stroke spastic hemiparesis-a randomized controlled clinical trial.

The objective of the study was to investigate the impact of photobiomodulation (PBM) on the paretic upper limb in post-stroke patients with spastic hemiparesis and to understand the potential of PBM as a long-term non-invasive therapy for reducing the side effects caused by spasticity in the hemiparetic upper limb after a stroke. This is a double-blind randomized clinical trial constituted of 27 participants, being Control group (CG = 12 healthy individuals) and PBM group (PBMG = 15 post-stroke individuals). In the CG, the baseline blood lactate (BL) was evaluated, followed by the evaluation of the IC torque of the biceps and triceps muscles, with the isokinetic dynamometer associated with surface electromyography (EMG) and, subsequently, a new measurement of BL. The PBMG received 10 sessions of treatment with PBM (780 nm, Power: 100 mV, Power Density: 3.18 W/cm2, Energy: 4 J, Fluency: 127.4 J/cm2, Time: 40 s per point and 1.280 s total, Spot: 0.0314 cm2, 32 Points: 16 points (brachial biceps) and 16 points (brachial triceps) applied with contact at 90°, Total Energy: 64 J), which in the pre-treatment evaluation measured BL, the visual analogue scale (VAS) of pain; torque and EMG of the same muscles in the IC, subsequently, a new measurement of VAS and BL, and measurement of range of motion (ROM) during the reaching movement. At the conclusion of the ten sessions, all participants underwent a reassessment, wherein all tests originally administered during the initial evaluation were repeated. Subsequently, the data were analyzed using the Shapiro-Wilk normality test. For related data, the paired t-test was used for normal distributions and the Wilcoxon test for non-normal data. For unrelated data, the t test was used for normal distributions and the Mann-Whitney test for non-normal data. Muscle torque was higher for the CG, with a significant difference (CGxPBMG = p < 0.0001). There was no significant difference between the EMG values of the CG in relation to the Pre-PBM phase and with the Post-PBM phase of the PBMG (p > 0.05). On the other hand, there was a 38% reduction in pain reported by hemiparetic patients (p = 0.0127) and a decrease in BL in the PBMG. Post-PBM ROM increased by 46.1% in the elbow extension of the paretic limb. In conclusion, Photobiomodulation (PBM) demonstrated significant improvements in muscle performance, reducing fatigue and pain levels, and enhancing range of motion in post-stroke patients with spastic hemiparesis. These findings support the potential integration of PBM into rehabilitation protocols, but further research and clinical trials are needed to validate and expand upon these promising outcomes.

Scalp acupuncture for post-stroke spastic hemiparesis: A systematic review and meta-analysis.

BACKGROUND: Spastic paralysis is one of the most common sequelae of stroke, severely affecting patients' limb function and reducing their quality of life. Scalp acupuncture (SA) has been shown to significantly improve cerebral blood supply and reduce the severity of limb spasticity. This meta-analysis aims to systematically evaluate the clinical efficacy of SA in the treatment of post-stroke spastic paralysis, providing evidence-based medicine for clinical management of this condition. METHODS: We comprehensively searched databases including China National Knowledge Infrastructure, Wanfang Data, VIP Chinese Science and Technology Periodical Database, China Biomedical Literature Database, PubMed, Embase, and Cochrane Library. Randomized controlled trials investigating the efficacy of SA in post-stroke spastic paralysis were identified until July 28, 2023. Meta-analysis was conducted using RevMan 5.4 and Stata17.0. RESULTS: A total of 16 studies were included. Meta-analysis showed that the modified Ashworth spasticity assessment scale in the SA group was significantly higher than that in the rehabilitation group (mean difference [MD] = -0.56, 95% confidence interval [CI] [-0.75, -0.37], Z = 5.67, P < .00001). The simplified Fugl-Meyer motor function assessment scale in the SA group was significantly higher than that in the rehabilitation group (MD = 5.86, 95% CI [3.26, 8.46], Z = 4.41, P < .0001). The modified Barthel index assessment scale in the SA group was significantly higher than that in the rehabilitation group (MD = 5.79, 95% CI [4.73, 6.84], Z = 10.77, P < .00001). Additionally, the clinical effective rate in the SA group was significantly higher than that in the rehabilitation group (relative risk = 1.25, 95% CI [1.16, 1.36], Z = 5.42, P < .00001). CONCLUSION: SA combined with rehabilitation therapy has certain advantages in reducing limb spasticity, improving limb function, and enhancing activities of daily living in patients with post-stroke spastic paralysis. This study provides reference and theoretical support for the promotion of SA in the treatment of this condition.

Bilateral effect of acupuncture on cerebrum and cerebellum in ischaemic stroke patients with hemiparesis: a randomised clinical and neuroimaging trial.

BACKGROUND: Acupuncture involving the limb region may be effective for stroke rehabilitation clinically, but the visualised and explanatory evidence is limited. Our objectives were to assess the specific effects of acupuncture for ischaemic stroke (IS) patients with hemiparesis and investigate its therapy-driven modification in functional connectivity. METHODS: IS patients were randomly assigned (2:1) to receive 10 sessions of hand-foot 12 needles acupuncture (HA, n=30) or non-acupoint (NA) acupuncture (n=16), enrolling gender-matched and age-matched healthy controls (HCs, n=34). The clinical outcomes were the improved Fugl-Meyer Assessment scores including upper and lower extremity (ΔFM, ΔFM-UE, ΔFM-LE). The neuroimaging outcome was voxel-mirrored homotopic connectivity (VMHC). Static and dynamic functional connectivity (sFC, DFC) analyses were used to study the neuroplasticity reorganisation. RESULTS: 46 ISs (mean(SD) age, 59.37 (11.36) years) and 34 HCs (mean(SD) age, 52.88 (9.69) years) were included in the per-protocol analysis of clinical and neuroimaging. In clinical, ΔFM scores were 5.00 in HA group and 2.50 in NA group, with a dual correlation between ΔFM and ΔVMHC (angular: r=0.696, p=0.000; cerebellum: r=-0.716, p=0.000) fitting the linear regression model (R2=0.828). In neuroimaging, ISs demonstrated decreased VMHC in bilateral postcentral gyrus and cerebellum (Gaussian random field, GRF corrected, voxel p<0.001, cluster p<0.05), which fitted the logistic regression model (AUC=0.8413, accuracy=0.7500). Following acupuncture, VMHC in bilateral superior frontal gyrus orbital part was increased with cerebro-cerebellar changes, involving higher sFC between ipsilesional superior frontal gyrus orbital part and the contralesional orbitofrontal cortex as well as cerebellum (GRF corrected, voxel p<0.001, cluster p<0.05). The coefficient of variation of VMHC was decreased in bilateral posterior cingulate gyrus (PPC) locally (GRF corrected, voxel p<0.001, cluster p<0.05), with integration states transforming into segregation states overall (p<0.05). There was no acupuncture-related adverse event. CONCLUSIONS: The randomised clinical and neuroimaging trial demonstrated acupuncture could promote the motor recovery and modified cerebro-cerebellar VMHC via bilateral static and dynamic reorganisations for IS patients with hemiparesis.

"Inspiratory muscle weakness in acutely hospitalized patients 75 years and over": a secondary analysis of a randomized controlled trial on the effectiveness of multicomponent exercise and inspiratory muscle training.

PURPOSE: The impact of hospitalization for acute illness on inspiratory muscle strength in oldest-old patients is largely unknown, as are the potential benefits of exercise and inspiratory muscle training (IMT) during in-hospital stay. DESIGN AND METHODS: This was a sub-study of a randomized clinical trial that evaluated the efficiency of a multicomponent exercise program in preventing hospitalization-associated disability. Patients were randomized into control (CG) and intervention (IG) groups. The intervention included two daily sessions of supervised walking, squat, balance, and IMT. Baseline and discharge maximal inspiratory pressure (MIP) and inspiratory muscle weakness (IMW) were determined. The effect of the intervention on inspiratory muscle strength was assessed by analyzing (1) the differences between groups in baseline and discharge MIP and IMW, (2) the association, patient by patient, between baseline and discharge MIP, and the improvement index (MIP discharge/baseline) in patients with or without IMW. RESULTS: In total, 174 patients were assessed (mean age of 87), 57 in CG and 117 in IG. Baseline MIP was lower than predicted in both sexes (women 29.7 vs 44.3; men 36.7 vs 62.5 cmH2O, P < 0.001, baseline vs predicted, respectively). More than 65% of patients showed IMW at admission. In women in IG, the mean MIP was higher at discharge than at admission (P = 0.003) and was the only variable that reached expected reference levels at discharge (Measured MIP 39.2 vs predicted MIP 45 cmH2O, P = 0.883). Patients with IMW on admission showed a statistically significant improvement in MIP after the intervention. CONCLUSION: IMW is very prevalent in oldest-old hospitalized with acute illness. Patients might benefit from a multicomponent exercise program including IMT, even during short-stay hospitalization. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov; No.: NTC03604640. May 3, 2018.

Ramen noodle neuropathy: an atypical case of partial paralysis from malnutrition.

INTRODUCTION: Due to a COVID-related job loss resulting in financial and food insecurity, a 28-year-old woman initiated a diet consisting solely of one cup of ramen noodles daily for twenty-two months, leading to 27 kg of weight loss. Ramen noodles are low in calories and lack key nutrients, including potassium, chloride, and vitamin B12. CASE DESCRIPTION: The patient presented to the emergency department with acute, worsening weakness and paresthesias in her left wrist and hand. Exam revealed no other abnormalities aside from a cachectic appearance. Labs revealed marked hypokalemia, hypochloremia, lactic acidosis, a mixed metabolic alkalosis with respiratory acidosis, and low levels of zinc and copper. An EKG revealed a prolonged QT interval. After a neurology and psychiatry consult, the patient was admitted for failure to thrive with malnutrition, peripheral neuropathy, hypokalemia, and an acid-base disorder. An MRI of the brain was unremarkable. Studies of other nutritional deficiencies, autoimmune conditions, and sexually transmitted infections were unremarkable. The patient received food and vitamin supplementation, was monitored for re-feeding syndrome, and had a significant recovery. DISCUSSION: After stroke, spinal injury, multiple sclerosis, and the most common focal mononeuropathies were ruled out, the clinical focus turned to nutritional deficiencies, the most significant of which was hypokalemia. Prior research has shown that severe hypokalemia can lead to weakness. It has also shown that chronically insufficient dietary intake is a common cause of hypokalemia. This case, with its partial paralysis of a unilateral upper extremity, may add to the known clinical manifestations of hypokalemia. We review the role of hypokalemia and hypochloremia in acid-base dynamics. Etiologies and clinical manifestations of cobalamin, thiamine, pyridoxine, and copper deficiencies, along with lead toxicity, are also discussed. Diagnostic clarity of mononeuropathies in the context of malnutrition and hypokalemia can be aided by urine potassium levels prior to repletion, neuroimaging that includes the cervical spine, and follow-up electromyography.

Kinesiology taping and ankle foot orthosis equivalent therapeutic effects on gait function in stroke patients with foot drop: A preliminary study.

An ankle foot orthosis (AFO) is a standard type of orthosis applied to immediately treat foot drop symptoms. Kinesiology taping (KT) is a therapeutic method used in patients with neurological diseases, such as stroke, as well as in patients after orthopedic and sports injuries. This study aimed to compare outcomes of AFO treatment with those of KT to investigate the effect on gait ability in patients with foot drop after stroke. We recruited 18 patients exhibiting foot drop from stroke. Gait ability was assessed under 2 conditions: treatment with KT and that with AFO using the GAITRite system according to the following parameters: cadence, velocity, swing time, stance time, step length, and stride length. As a result, gait ability after treatment with KT and that after treatment with AFO showed no significant differences in cadence (P = .851), velocity (P = .865), swing time (P = .289 and .123), stance time (P = .255 and .711), step length (P = .955 and .975), and stride length (P = .711 and .690) of the affected and less-affected limbs. This study demonstrated that KT and AFO use have similar effects on gait function in patients with foot drop after stroke. Thus, treatment of foot drop with KT may be an alternative in patients for whom AFO use is contraindicated.

Segmental zoster paresis of the lower extremity: Case report.

Herpes zoster (HZ) is a segmental vesicular eruption, pain, and sensorial symptoms. Segmental motor weakness can rarely be seen as a complication of HZ. Here, we present two cases of motor paresis associated with HZ, case 1 was L2 and L3 segmental motor paresis with femoral neuropathy and case 2 was L5 and S1 segmental motor paresis with sensorial ganglion involvement. In both cases after electrotherapy, exercise program, and medication for pain, there were no motor weakness and pain. Zoster motor paresis is a rare complication that responds to treatment and physicians should be careful about its presence in clinical follow-up.

Shoulder complex and trunk coordination of individuals with severe hemiparesis following a constraint-induced movement therapy protocol: A case series.

INTRODUCTION: Constraint Induced Movement Therapy (CIMT) has been shown to be an effective rehabilitation technique in individuals with mild and moderate upper limb (UL) hemiparesis. The aim was to evaluate the effect the CIMT for improving paretic UL use and interjoint coordination with individuals in severe hemiparesis. METHODS: Six individuals with severe chronic hemiparesis (mean age = 55 ± 16 years) received a UL CIMT intervention for 2 weeks. UL clinical assessments were conducted five times: two assessments at pre-intervention and then, one assessment at post-intervention and 1- and 3-month follow-up using the Graded Motor Activity Log GMAL) and the Graded Wolf Motor Function Test (GWMFT). Scapula, humerus and trunk coordination variability were assessed using the 3-D kinematics during arm elevation, combing hair, turning on the switch and grasp a washcloth. A paired t-test was used to check differences between coordination variability and a one-way ANOVA repeated measures was used to check differences between GMAL and GWMFT scores. RESULTS: There were no differences in GMAL and GWMFT between the patient screening and the baseline data collection (p > 0.05). GMAL scores increased at post-intervention and at follow-ups (p < 0.02). GWMFT performance time score decreased at post-intervention and at 1-month follow-up (p < 0.04). Improvements in kinematic variability of the paretic UL at pre and post-intervention were observed in all tasks, except in the activity of turn on the light switch. CONCLUSION: Following the CIMT protocol, improvements in GMAL and GWMFT scores may reflect improvements in paretic UL performance, in real-life environment. Improvements in kinematic variability may reflect an improving of UL interjoint coordination for individuals with chronic severe hemiparesis.

Gamma Knife Thalamotomy for Essential Tremor: A Retrospective Analysis.

BACKGROUND: Gamma knife (GK) thalamotomy has been used as a treatment option for essential tremor (ET). Numerous studies on GK use in ET treatment have reported more varied responses and complication rates. METHODS: Data from 27 patients with ET who underwent GK thalamotomy were retrospectively analyzed. The Fahn-Tolosa-Marin Clinical Rating Scale for Tremor, handwriting, and spiral drawing were evaluated. Postoperative adverse events and magnetic resonance imaging findings were also evaluated. RESULTS: The mean age at GK thalamotomy was 78.1 ± 4.2 years. The mean follow-up period was 32.5 ± 19.4 months. The preoperative postural tremor, handwriting, and spiral drawing scores were 3.4 ± 0.6, 3.3 ± 1.0, and 3.2 ± 0.8, respectively, all of which showed significant improvements to 1.5 ± 1.2 (55.9% improvement, P < 0.001), 1.4 ± 1.1 (57.6% improvement, P < 0.001), and 1.6 ± 1.3 (50% improvement, P < 0.001), respectively, at the available final follow-up evaluations. Three patients presented with no improvement in tremor. Six patients presented with adverse effects, including complete hemiparesis, foot weakness, dysarthria, dysphagia, lip numbness, and finger numbness, at the final follow-up period. Two patients presented with serious complications, including complete hemiparesis due to massive widespread edema and chronic encapsulated expanding hematoma. One patient died of aspiration pneumonia following severe dysphagia secondary to chronic encapsulated expanding hematoma. CONCLUSIONS: GK thalamotomy is an efficient procedure for treating ET. Careful treatment planning is necessary to reduce complication rates. The prediction of radiation complications will increase the safety and effectiveness of GK treatment.

Efficacy of individualized homeopathic medicines in treatment of post-stroke hemiparesis: A randomized trial.

BACKGROUND: Hemiparesis is a serious motor impairment following stroke and affecting around 65% of stroke patients. This trial attempts to study the efficacy of individualized homeopathic medicines (IHMs) in comparison with identical-looking placebos in treatment of post-stroke hemiparesis (PSH) in the mutual context of standard physiotherapy (SP). METHODS: A 3-months, open-label, randomized, placebo-controlled trial (n = 60) was conducted at the Organon of Medicine outpatient departments of National Institute of Homoeopathy, West Bengal, India. Patients were randomized to receive IHMs plus SP (n = 30) or identical-looking placebos plus SP (n = 30). Primary outcome measure was Medical Research Council (MRC) muscle strength grading scale; secondary outcomes were Stroke Impact Scale (SIS) version 2.0, Modified Ashworth Scale (MAS), and stroke recovery 0-100 visual analogue scale (VAS) scores; all measured at baseline and 3 months after intervention. Group differences and effect sizes (Cohen's d) were calculated on intention-to-treat sample. RESULTS: Although overall improvements were higher in the IHMs group than placebos with small to medium effect sizes, the group differences were statistically non-significant (all P>0.05, unpaired t-tests). Improvement in SIS physical problems was significantly higher in IHMs than placebos (mean difference 2.0, 95% confidence interval 0.3 to 3.8, P = 0.025, unpaired t-test). Causticum, Lachesis mutus, and Nux vomica were the most frequently prescribed medicines. No harms, unintended effects, homeopathic aggravations or any serious adverse events were reported from either group. CONCLUSION: There was a small, but non-significant direction of effect favoring homeopathy against placebos in treatment of post-stroke hemiparesis. TRIAL REGISTRATION: CTRI/2018/10/016196; UTN: U1111-1221-7664.

Evaluation of the Effect of SPIDER System Therapy on Weight Shifting Symmetry in Chronic Stroke Patients-A Randomized Controlled Trial.

(1) Background: The Strengthening Program for Intensive Developmental Exercises and Activities for Reaching Health Capability (SPIDER) system is dedicated to patients with motor deficits resulting from damage to the peripheral or central nervous system (including post-stroke patients). It enables the conduct of forced-weight-bearing therapy to the lower limb affected by the paresis. In this study, the TYMO® measuring platform was used to quantify the impact of therapy using the SPIDER system and therapy that did not use this system. The TYMO® device is a portable posturography platform that monitors the tilting of the body's center of mass and reports the results of the rehabilitation process. (2) Objective: To evaluate the effect of therapy based on neurophysiological methods (proprioceptive neuromuscular facilitation (PNF), neurodevelopmental treatment according to the Bobath concept (NDT-Bobath)) and the SPIDER system on body weight transfer shifting, in post-stroke patients in the chronic phase, compared to therapy based on neurophysiological methods (PNF, NDT-Bobath), without the use of the SPIDER system. (3) Methods: This is a randomized controlled trial in which patients (n = 120; adults, post-ischemic stroke-first stroke episode, in chronic phase-up to 5 years after the stroke incident) were assigned to one of two groups: study, n = 60 (with therapy using PNF, NDT-Bobath methods and the SPIDER system); and control, n = 60 (with therapy using PNF and NDT-Bobath methods, without the SPIDER system). In patients in both groups, before and after the training (2 weeks of therapy), body weight distribution was measured on the TYMO® platform. (4) Results and Conclusions: The results of the statistical analysis demonstrated a greater reduction in the tilt of the body's center of mass in therapy using the SPIDER system, compared to therapy in which the system was not used.

[Electroacupuncture promotes gastrointestinal motility by activating autophagy of Cajal interstitial cells via downregulating PI3K/Akt/mTOR signaling pathway in stomach of diabetic gastro-paresis rats].

OBJECTIVE: To observe the effect of electroacupuncture (EA) of "Zusanli" (ST36), "Sanyinjiao" (SP6) and "Liangmen" (ST21) on gastrointestinal motility, blood glucose content and expression of autophagy-related proteins 1 light chain 3 (LC3), p62, phosphatidyli-nositol-3 kinase (PI3K), protein kinase B (Akt), p-Akt and mammalian target protein of rapamycin (mTOR) of interstitial cells of Cajal (ICCs) in the cultured gastric antrum cells in diabetic gastroparesis (DGP) rats, so as to reveal its mechanisms underlying improvement of DGP. METHODS: A total of 45 Sprague Dawley (SD) rats were randomly divided into blank control, model, EA, medication (3-methyladenine, 3-MA) and EA+3-MA groups, with 9 rats in each group. The DGP model was established by intraperitoneal injection of 2% streptozotocin (STZ) combined with high-fat and high sugar diet for 8 weeks. The gastric emptying rate was measured by using gavage of phenol red (to measure the propelling length of the phenol red/total length of small intestine ×100%). The symptom score (mental state, coat color and luster, behavior and activity, stool traits) of rats was observed every week and the blood glucose content was measured by using a glucometer. EA (20 Hz/100 Hz, 2 mA) was applied to unilateral ST36, SP6 and ST21 alternatively for 15 min, once daily, 5 days a week for 3 weeks. Rats of the 3-MA and 3-MA+EA groups received intraperitoneal injection of 3-MA (30 mg·kg-1·d-1, 10 mg/mL), once daily, 5 days a week for 3 weeks. After 15 days' intervention, the rats were operated for gastric emptying rate test, specimen collection, isolation, and culture of primary ICCs. The expression levels of microtubule associated protein LC3, p62, PI3K, Akt, p-Akt and mTOR of ICCs of cultured gastric antrum cells were detected using Western blot, and the number of autophagosomes in ICC of gastric antrum was observed under transmission electron microscope. RESULTS: Compared with the blank control group, the symptom score, blood glucose, and the expression levels of p62, class Ⅰ PI3K, Akt, p-Akt and mTOR proteins were increased significantly (P<0.01), while the gastric emptying rate and ratio of LC3Ⅱ/LC3Ⅰ and the expression level of class Ⅲ PI3K protein were significantly decreased (P<0.05, P<0.01) in the model group. In comparison with the model group, the increase of symptom score, blood glucose, and expression levels of p62, class Ⅰ PI3K, Akt, p-Akt and mTOR proteins and the decrease of gastric empty rate and LC3Ⅱ/LC3Ⅰ ratio and the expression level of class Ⅲ PI3K protein were all reversed in both EA and EA+3-MA groups (P<0.05, P<0.01), rather than in the 3-MA group. In addition, 3-MA also reversed modeling-induced increase of class Ⅰ PI3K, Akt, p-Akt and mTOR proteins expression (P<0.01). No significant differences were found between the EA and EA+3-MA in downregulating the levels of symptom score and blood glucose content, and in upregulating gastric empty rate(P>0.05). The effect of EA was notably superior to that of EA+3-MA in upregulating the ratio of LC3Ⅱ/LC3Ⅰ and the expression level of class Ⅲ PI3K protein, and in downregulating the expression of p62, class Ⅰ PI3K, Akt, p-Akt and mTOR proteins (P<0.05, P<0.01). The findings of transmission electron microscopy showed obvious swelling, breakage of some mitochondrial cristae in the ICC cells of antrum and no autophagosomes in the model group and 3-MA group, which was milder in the damage of mitochondrial cristae and marked increase in the autophagosomes in both EA and EA+3-MA groups. CONCLUSION: EA can improve the gastrointestinal motility and symptoms in DGP rats, which may be related to its functions in downregulating PI3K/Akt/mTOR signaling to promote autophagy level of ICC.

Hypokalemic Paresis in a 26-Year-Old Man After Recreational Cannabis Use.

BACKGROUND Hypokalemia (serum potassium level below 3.5 mmol/L) is present in approximately 11% of patients admitted to emergency departments. Hypokalemia can be a manifestation of many underlying causes and if untreated can be fatal. A careful approach to work-up and management is required in hypokalemic patients. CASE REPORT Here we report a 26-year-old previously healthy male patient who was admitted to the Emergency Department with rapidly progressing paresis of the lower and upper extremities. Initial laboratory results revealed severe hypokalemia of 2.1 mmol/l, which aggravated to 1.6 mmol/l before receiving treatment with intravenous potassium chloride supplementation. In addition, the patient developed rhabdomyolysis secondary to prolonged paralysis and immobilization induced by hypokalemia. Following this treatment, the patient's symptoms eased rapidly, and his potassium concentration was normalized. The patient admitted to smoking cannabis the day before admission. In this case report, we systematically elaborate and exclude the causes of hypokalemia in this otherwise healthy young adult, including medication, gastrointestinal symptoms, licorice consumption, and genetical testing. Cannabis has been associated with hypokalemia, proposedly through activation of the cannabinoid receptor 1 (CB1)-mediated activation of G protein-coupled inwardly rectifying potassium (GIRK) channels. CONCLUSIONS This case report emphasizes that hypokalemia can cause paralysis and cannabis should be included in the diagnostic mindset.

Parents' perceptions of functional electrical stimulation as an upper limb intervention for young children with hemiparesis: qualitative interviews with mothers.

BACKGROUND/OBJECTIVE: To explore parents' perceptions of an upper extremity (UE) intervention using functional electrical stimulation (FES) for young children with hemiparesis. METHODS: Parents of children aged 3-6 years with a history of perinatal stroke, impaired UE function, and participation in a 12-week FES intervention delivered at a hospital were included in this exploratory qualitative study. Nine mothers participated in a semi-structured interview < 1 week after their child completed the FES intervention (MyndMove®, MyndTec Inc.) targeting the hemiparetic UE. Open-ended questions queried parents' goals, perceived benefits, and challenges of the FES intervention. Interviews were audio recorded and transcribed verbatim. Qualitative conventional content analysis was used to analyze the transcripts. RESULTS: Five themes were identified. 1) Parents' expectations for the FES intervention. Mothers described setting functional, exploratory, and realistic goals, yet feeling initial apprehension towards FES. 2) Perceived improvement. Physical, functional, and psychological improvements were observed with FES; however, there was still room for improvement. 3) Factors influencing the FES intervention. Program structure, therapist factors, and child factors influenced perceived success. 4) Lack of access to intensive therapy. Mothers noted that FES is not provided in mainstream therapy; however, they wanted access to FES outside of the study. They also highlighted socioeconomic challenges to accessing FES. 5) Strategies to facilitate participation. The mothers provided suggestions for program structure and delivery, and session delivery. CONCLUSIONS: Mothers perceived the FES intervention to have physical, functional and psychological benefits for their children. Interest in continuing with FES highlights a need to improve access to this therapy for young children.

[Restoration of hand function in patients with hemiparesis using mirror therapy in combination with myofascial stretching and postisometric relaxation]. / Vosstanovlenie funktsii kisti u patsientov s gemiparezom s primeneniem metoda zerkal'noi terapii v sochetanii s miofastsial'nym rastyazheniem i postizometricheskoi relaksatsiei.

The increase in the number of cerebral strokes is accompanied by the accumulation of patients with hemiparesis. It is especially difficult to restore the function of the upper limb, in particular the hand, which significantly limits the social, domestic and labor adaptation of patients. This makes it relevant to search for new methods for restoring the functions of the hand. Today, mirror therapy is becoming increasingly popular, which, however, does not eliminate myogenic contractures in the joints of a paralyzed limb. PURPOSE OF THE STUDY: Rationale for the use of mirror therapy in combination with myofascial stretching and postisometric relaxation in patients with hemiparesis. MATERIAL AND METHODS: 277 patients with hemiparesis were examined, of which 68 patients were included in the main group; 209 - to the comparison group. All patients underwent a course of rehabilitation treatment for 10 days. Patients of the main group additionally received mirror therapy in combination with myofascial stretching and post-isometric relaxation: course - 10 individual sessions, session duration - 30 minutes. Upon admission and before discharge, patients were evaluated for neurological status, severity of spastic and pain syndromes; the strength of the muscles of the paralyzed upper limb according to the Lovett scale; tested self-service skills in accordance with the International Classification of Functioning, Disabilities and Health. RESULTS: In patients of both groups, the severity of spastic and pain syndromes decreased, muscle strength increased. In the main group, these changes were more pronounced; 35 patients of the main group mastered new types of grip, which statistically significantly improved their social adaptability. CONCLUSION: Mirror therapy in combination with soft manual therapy techniques is able to restore precise targeted movements in the joints of the hand and fingers, form different grip options, which expands the possibilities of self-care for patients.

Effectiveness of Repetitive Facilitative Exercise Combined with Electrical Stimulation Therapy to Improve Very Severe Paretic Upper Limbs in with Stroke Patients: A Randomized Controlled Trial.

Background: The difference in the effects of combined therapy with repetitive facilitative exercise (RFE) and neuromuscular electrical stimulation (NMES) on stroke upper limb paralysis was only reported by a pilot study; it has not been investigated in many patients. Objective: We investigated the effect of combined therapy with RFE and NMES on stroke patients with severe upper paresis. Methods: This study included 99 of the very severe paresis stroke patients with scores of zero or 1a in the Finger-Function test of the Stroke Impairment Assessment Set (SIAS). We randomly divided the patients into four groups, namely, NMES, RFE, RFE under NMES, and conventional training (CT) groups. A total of 20 min of group-specific training in addition to 40 min of conventional exercise per day, seven times a week for 4 weeks after admission, was performed. The upper extremity items of the Fugl-Meyer Assessment (FMA) were evaluated before and after the training period. Results: The total score gains of the FMA, FMA wrist item, and FMA finger item were significantly larger in the RFE under NMES group than those in the CT group (p < 0.05). Conclusion: The combination of voluntary movement and electrical stimulation may promote the activation of paralyzed muscles and improve distal function for very severe paralyzed upper limbs.

Utilização da fisioterapia na reabilitação de bezerro com poliartrite e paresia neuromuscular: relato de caso / Use of physiotherapy in the rehabilitation of calves with polyarthritis and neuromuscular paresis: case report / Uso de la fisioterapia en la rehabilitación de un ternero con poliartritis y parisia neuromuscular: reporte de caso

A reabilitação animal na medicina veterinária é um campo recente, porém crescente a cada dia. Neste sentido, a fisioterapia veterinária atua trazendo inúmeros benefícios, como melhoria dos movimentos, redução da dor, edema e outras. Interfere ainda no tempo de recuperação, redução de custos para o proprietário, podendo ser hoje utilizada como um tratamento na recuperação pós-cirúrgica. Desta forma, objetivou-se relatar o uso da fisioterapia em uma bezerra com poliartrite e paresia neuromuscular. O animal apresentou um aumento de volume nas articulações cárpicas e társicas após histórico de onfalite, permanecendo em decúbito esternal por vários dias. O proprietário resolveu aplicar ferro dextrano na região glútea do animal, o que causou uma lesão de nervo isquiático. Foram instituídos protocolos medicamentosos e fisioterápicos, que culminaram no estímulo da marcha, propriocepção, além de hipertrofia muscular. Porém, em virtude de complicações resultantes de onfalite, o animal veio a óbito.(AU)

Animal rehabilitation in veterinary medicine is a recent field, but growing every day. In this sense, veterinary physiotherapy works bringing numerous benefits, such as improved movements, reduced pain, edema and others. Reducing the recovery time, reducing costs for the owner, and today it can be used as a treatment in post-surgical recovery. In this sense, the objective was to report the use of physiotherapy in a heifer with polyarthritis and neuromuscular paresis. The animal showed an increase in volume in the carpal and tarsal joints after a history of omphalitis, remaining in sternal decubitus for several days. The owner decided to apply iron dextran to the animal's gluteal region, which caused an injury to the sciatic nerve. Medicinal and physical therapy protocols were instituted, which culminated in the stimulation of gait, proprioception, in addition to muscle hypertrophy. However, due to complications resulting from omphalitis, the animal died.(AU)

La rehabilitación animal en medicina veterinaria es un campo reciente, pero en crecimiento cada día. En este sentido, la fisioterapia veterinaria actúa aportando numerosos beneficios, como mejora de los movimientos, reducción del dolor, edemas y otros. Disminución del tiempo de recuperación, reducción de costos para el propietario, pudiendo ser utilizado hoy en día como tratamiento en la recuperación posquirúrgica. En ese sentido, el objetivo fue reportar el uso de fisioterapia en una vaquilla con poliartritis y paresia neuromuscular. El animal presentó un aumento de volumen en las articulaciones del carpo y del tarso tras un antecedente de onfalitis, permaneciendo en decúbito esternal durante varios días. El propietario decidió aplicar hierro dextrano en la región glútea del animal, lo que provocó una lesión en el nervio ciático. Se instauraron protocolos farmacológicos y de fisioterapia, que culminaron con estimulación de la marcha, propiocepción, además de hipertrofia muscular. Sin embargo, debido a complicaciones derivadas de la onfalitis, el animal falleció.(AU)

A scoping review of the contralateral effects of unilateral peripheral stimulation on neuromuscular function.

It is known that resistance exercise using one limb can affect motor function of both the exercised limb and the unexercised contralateral limb, a phenomenon termed cross-education. It has been suggested that cross-education has clinical implications, e.g. in rehabilitation for orthopaedic conditions or post-stroke paresis. Much of the research on the contralateral effect of unilateral intervention on motor output is based on voluntary exercise. This scoping review aimed to map the characteristics of current literature on the cross-education caused by three most frequently utilised peripheral neuromuscular stimulation modalities in this context: electrical stimulation, mechanical vibration and percutaneous needling, that may direct future research and translate to clinical practice. A systematic search of relevant databases (Ebsco, ProQuest, PubMed, Scopus, Web of Science) through to the end of 2020 was conducted following the PRISMA Extension for Scoping Review. Empirical studies on human participants that applied a unilateral peripheral neuromuscular stimulation and assessed neuromuscular function of the stimulated and/or the unstimulated side were selected. By reading the full text, the demographic characteristics, context, design, methods and major findings of the studies were synthesised. The results found that 83 studies were eligible for the review, with the majority (53) utilised electrical stimulation whilst those applied vibration (18) or needling (12) were emerging. Although the contralateral effects appeared to be robust, only 31 studies claimed to be in the context of cross-education, and 25 investigated on clinical patients. The underlying mechanism for the contralateral effects induced by unilateral peripheral stimulation remains unclear. The findings suggest a need to enhance the awareness of cross-education caused by peripheral stimulation, to help improve the translation of theoretical concepts to clinical practice, and aid in developing well-designed clinical trials to determine the efficacy of cross-education therapies.

Effects of Citrus depressa Hayata Fruit Extract on Thigh Muscles Mass and Composition in Subacute Stroke Patients: A Double-Blind, Randomized, Controlled Pilot Trial.

Objective: This pilot study evaluated the effects of Citrus depressa Hayata fruit extract (CFEx) on thigh muscle cross-sectional area (CSA) and composition in subacute stroke patients with hemiparesis who were undergoing rehabilitation. Design and Intervention: This double-blinded, placebo-controlled, randomized pilot trial included 40 subacute stroke patients with moderate-to-severe hemiparesis, and they were randomly assigned to receive CFEx or placebo supplements for 12 weeks. The thigh muscle CSA was measured by computed tomography as total muscle area defined by Hounsfield units (HU) values of -29 to 150 HU. The total muscle area was divided into muscle area with fat infiltration and normal muscle area to evaluate muscle composition (-29 to 29 and 30 to 150 HU, respectively). Results: At baseline, the total muscle area and normal muscle area in the paretic thigh were lower than those in the nonparetic thigh. The nonparetic normal muscle area was significantly higher in the CFEx group than in the placebo group at 12 weeks, whereas the total muscle area was not different. Conclusions: The thigh muscle CSA and composition in the paretic side have already deteriorated in patients with moderate-to-severe hemiparesis at the subacute stroke stage. CFEx supplementation during rehabilitation might improve the nonparetic thigh muscle composition in subacute stroke patients. Findings of this study are needed to be verified by a large-scale randomized trial since this study was a pilot study with a small sample size.
