A systematic review of upper extremity outcome measures assessed in randomized controlled trials of post stroke upper extremity rehabilitation over time

ABSTRACT Background The heterogeneity in outcome measures of post stroke rehabilitation trials suggests the need for consensus approach in stroke recovery measurement. To reach this aim, it is important to understand the past and current use of outcome measures in randomized control trials (RCTs) of stroke rehabilitation. Objective To systematically review RCTs of post stroke UE rehabilitation interventions to understand the use of UE outcome measures in research and their changes over time. Methods CINAHL, Embase, PubMed, Scopus and Web of Science were searched from 1960 to 1 April 2021. Studies were eligible for inclusion if they (1) were RCTs or crossovers published in English (2) ≥50% of participants were affected by stroke, 3) included adults ≥ 18 years old, and (4) applied an intervention to the hemiparetic UE as the primary objective of the study. Results 1,276 RCTs met inclusion criteria, and 112 different outcome measures were identified. Outcome measures were classified according to the International Classification of Functioning, Disability and Health (ICF) framework. Outcome measures most frequently assessed body function and structure (n = 1,692), followed by activities (n = 1,572) and participation (n = 162). The most used outcome measures were the Fugl-Meyer Assessment (n = 619), the modified Ashworth Scale (n = 255), Action Research Arm Test (n = 211), Wolf Motor Function Test (n = 184), and Box and Block Test (n = 178). Conclusions Understanding the breadth of outcome measures that have been used over time emphasizes the need for proposed standardization of outcome measures but also the need to adjust and expand consensus recommendations based on past and ongoing research trends.

Clinical Measures for Tone Assessment in Adults with Central Nervous System Disorders—A Scoping Review in a Rehabilitation Context

Assessment of muscle tone in a clinical setting is important for the physiotherapist to better analyse and establish appropriate treatments for CNS disorders. This study aims to review and summarise how to assess changes in tone in the context of adult rehabilitation. Secondarily, this study aimed to identify the central nervous system disorders, the respective variable/concept under study, and the testing procedures employed. PRISMA-ScR guidelines were followed using the “population”, “concept”, and “context” to define the eligibility criteria and to delineate the research question. PubMed®, Science Direct®, Web of Science™, and Google Scholar® databases were used to search the literature. The search included studies published between 2011 and March 2023 in Portuguese, English, French, and Spanish that assessed an adult population (>19 years) with CNS injury. Review articles, qualitative studies, conference proceedings, letters to the editor, and editorials were excluded. Initially, 1519 references were identified, of which eight met the eligibility criteria. The measurement instruments included the Modified Ashworth Scale (n = 5), the Modified Modified Ashworth Scale (n = 3), the BioTone™ system (n = 2), the Montreal Spasticity Measurement (n = 1), and the Tone Evaluation Scale (n = 1). The health conditions considered included stroke sequelae (n = 7), multiple sclerosis (n = 4), spinal cord injuries (n = 4), cerebral palsy (n = 2), brain tumour (n = 2), and traumatic brain injuries (n = 3). The concepts of spasticity (n = 7) and muscle tone (n = 2) were explored. Considering the variables spasticity and muscle tone in different CNS disorders, mainly stroke, subjective instruments were preferred compared to objective ones, with the Modified Ashworth Scale being highlighted.

Is the Silfverskiöld Test a valid tool for evaluating calf muscles spastic overactivity in patients with stroke? A retrospective observational study.

Spastic equinus (plantar flexed) foot is a common postural pattern in patients who suffer from post-stroke spasticity. To date, some clinicians use the Silfverskiöld Test in their practice to differentiate between gastrocnemius and soleus muscle overactivity in patients with spastic equinus (plantar flexed) foot. This use of the Silfverskiöld Test goes beyond its original aim, which was to distinguish isolated gastrocnemius contracture in patients with equinus deformity. The aim of this study was to investigate the Silfverskiöld Test validity for evaluating spastic equinus (plantar flexed) foot (i.e., differentiation between gastrocnemius and soleus muscle overactivity) by checking its outcome against those of selective diagnostic nerve block of tibial motor nerve branches to the soleus, gastrocnemius and tibialis posterior muscles. The design of the study was retrospective observational. The study was set in a university hospital. Sixty-seven adult stroke patients with spastic equinus (plantar flexed) foot. Each patient underwent selective diagnostic nerve block of tibial motor nerve branches to the soleus, gastrocnemius and tibialis posterior muscles. All patients were evaluated before diagnostic nerve block by means of the Silfverskiöld Test which was considered positive when ankle joint passive dorsiflexion was greater with the knee flexed than extended. Furthermore, they were assessed before and after nerve block by means of the modified Ashworth Scale and the Tardieu Scale. Our sample included 41 males and 26 females (mean age 57.6 years) suffering from spastic equinus (plantar flexed) foot due to chronic stroke (mean time from onset 2.4 years). Forty-eight patients out of 67 presented with positive Silfverskiöld Test. The χ2 test showed no association between the Silfverskiöld Test and spastic overactivity of the gastrocnemius (P=0.253), soleus (P=0.605) and tibialis posterior (P=0.462) muscles as evaluated by serial selective diagnostic block of the tibial nerve motor branches. Our findings do not support the Silfverskiöld Test as a valid tool for evaluating spastic equinus (plantar flexed) foot to differentiate between gastrocnemius, soleus and tibialis posterior spastic muscle overactivity in adult patients with stroke. The choice for an appropriate management of spastic equinus (plantar flexed) foot in adults with stroke should not be mainly defined on the base of Silfverskiöld Test.

Effect of vibrotherapy on spasticity in the lower limbs in patients with traumatic spinal cord injury

Introduction: vibrotherapy is a physiotherapeutic strategy proposed for the modulation of spasticity in subjects with spinal cord injury (SCI). However, its application is carried out using high-tech and high-cost devices, not always available in the field of public health.The present study evaluated the neuromodulatory effect of a low-cost abdominal vibrating belt on spasticity in individuals with SCI.Methods: a single-blind crossover experimental study was carried out, in which the response to treatment, both immediate and delayed, was recorded using the modified Ashworth scale in 4 muscle groups of the lower limbs.Results: the responses, in the 22 subjects included, showed statistically significant differences in favor of the proposed treatment. Scores were found in favor of the operated group in the dimensions of immediate abductor (p=0.01), late abductor (p<0.02) and late knee flexor (p=0.005). When cohorting by type of injury, in subjects with S.L. complete the effect was more positive in the dimensions of immediate abductor (p<0.01), late abductor (p<0.01) and immediate knee flexor (p=0.025).Conclusions: it is concluded that the use of a low-cost abdominal vibrating belt is effective in reducing spasticity in individuals with L.M. complete; this effect seems to decrease in effectiveness as it moves away from the area of application of the stimulus.

Urinary disorders in patients diagnosed with organic brain pathology

Introduction. This study is relevant due to the high prevalence of organic brain pathology and the negative influence of urination disorders on the quality of life.Objective. To analyse the impaired function of lower urinary tracts in patients with organic brain pathology.Materials & methods. We analysed 607 patients with severe organic brain pathology (105 had traumatic spinal cord injury (TSCI) and 457 had consequences of acute stroke (AS)). We performed clinical urological examinations. During the survey, attention was paid to the presence of urinary tract pathology at the examining time and anamnesis. Structural changes in the urinary tract were objectively assessed. We objectively assessed structural changes in urinary tracts including prostate adenoma in men, insufficiency of pelvic floor muscles in women and strictures of the urethra or ureters. The degree of the spastic syndrome was assessed with the Ashworth Scale. The neurourological examination included cystometry with the measurement of bladder volume and post-void residual urine. The cognitive status of the patients was assessed with the MMSE (Mini-Mental State Examination) questionnaire. The correlation analysis between the degree of spastic syndrome measured with the Ashworth Scale and urination disorders was performed with Spearman rank correlation.Results. All patients had neurogenic dysfunction of the lower urinary tract. A combination of bladder retention and emptying disorders was found in 62 men older than 45yo with benign prostate hyperplasia (10,2% of all cases). An impaired accumulation function in history was found in 45 women older than 45yo (7,4% of all observations). The level of spasticity was 3 or 4 points on the Ashworth Scale in patients with TSCI and 2 to 4 points in those with AS. The analysis of correlations between the degree of spasticity and urination disorders showed a moderate relationship (r = 0,4) in patients with TSCI and a medium relationship (r = 0.65) in patients with AS.Conclusion. Neurogenic dysfunction of the lower urinary tract accompanies patients with severe organic brain pathology throughout their life and requires adequate correction.

Acupuncture and Acupoints for Managing Pediatric Cerebral Palsy: A Meta-Analysis of Randomized Controlled Trials.

Acupuncture is frequently used to manage pediatric cerebral palsy (CP), yet updated evidence is needed to guide future research and clinical practice. Seven databases were searched from 1994 to 26 June 2023. Randomized controlled trials (RCTs) involving body, scalp, or ear acupuncture for managing CP, excluding acupoint injection, catgut embedding, electro-acupuncture, or laser acupuncture, were included. Twenty RCTs with 1797 participants were analyzed. Acupuncture groups had better improvements in gross motor function measure (GMFM) scores by 5% (mean difference: 5.93, 95% CI: 3.67-8.19, p < 0.001, I2 = 57%); a 16% higher probability to yield prominent improvement in effectiveness rate (ER) (risk ratio: 1.16, 95% CI: 1.08-1.25, p < 0.001, I2 = 0%); and better outcomes in the Modified Ashworth Scale (MAS) (standardized mean difference [SMD]: 0.3, 95%, CI: 0.11-0.49, p < 0.001, I2 = 0%), the Berg Balance Scale (BBS) (SMD: 2.48; 95% CI: 2.00-2.97, p < 0.001, I2 = 72%) and ADL (SMD: 1.66; 95% CI: 1.23-2.08, p < 0.001, I2 = 91%). Studies with eight core acupoints identified from all ninety-five acupoints had better ER. Acupuncture, especially using core acupoints, may be effective for managing symptoms in children with CP.

Long-term repeated botulinum toxin a treatment over 12 years gradually changes gait characteristics: single-case study

Objective: To demonstrate the long-term efficacy of repeated botulinum toxin A injections into the same muscles for ameliorating lower limb spasticity and gait function. Design: Single-case study Patient: A 36-year-old woman with right cerebral haemorrhage received her first botulinum toxin A injection 1,296 days after onset. The patient underwent 30 treatments over 12 years after the first injection to improve upper and lower limb spasticity and abnormal gait patterns. The mean duration between injections was 147 days. Methods: The Modified Ashworth Scale, passive range of motion, gait velocity, and degree of abnormal gait patterns during treadmill gait were evaluated pre-injection and at 2, 6, and 12 weeks after every injection. Results: The follow-up period showed no injection-related adverse events. Comfortable overground gait velocity gradually improved over 30 injections. The Modified Ashworth Scale and passive range of motion improved after each injection. Pre-injection values of the degree of pes varus, circumduction, hip hiking, and knee extensor thrust improved gradually. However, the degree of contralateral vaulting, excessive lateral shift of the trunk, and insufficient knee flexion did not improve after 30 injections. Conclusion: Repeated botulinum toxin A injections effectively improve abnormal gait patterns, even when a single injection cannot change these values.

Complications of intrathecal baclofen therapy in children and young adults

OBJECTIVE The primary objective of this study was to determine the frequency and nature of complications that occur during intrathecal baclofen (ITB) therapy, including nonsurgical complications as well as complications associated with both implantation surgeries and subsequent revisions. METHODS The authors retrospectively reviewed the medical records of all patients who had baclofen pumps implanted at a tertiary children’s hospital from 2006 through June 2019. The study employed appropriate descriptive statistics and statistical models to analyze patient demographics, improvements in tone, and clinical complications. The authors evaluated the associations of complications as well as changes in modified Ashworth Scale (MAS) scores with various preexisting conditions (e.g., presence of gastrostomy tubes [G-tubes] and ventriculoperitoneal [VP] shunts) and surgical variations (e.g., use of newer [Ascenda] catheters and subfascial versus subcutaneous catheter tunneling). RESULTS One hundred forty-two pumps were implanted. Complications occurred in 111 patients (78.2%). The most frequent complications were catheter complications and pseudomeningoceles, each of which occurred in 63 (44%) patients. On multivariable analysis, pseudomeningoceles and percutaneous CSF leaks were significantly less likely when intrathecal catheters were placed via laminotomy versus spinal needle (OR 4.6, p = 0.044), and when catheters were passed from the posterior incision to the abdominal pump pocket deep to the thoracolumbar fascia rather than superficial to it (OR 2.7, p = 0.008). Preexisting G-tubes and VP shunts at the time of pump implantation were not associated with a significantly increased likelihood of pump malfunction or infection. Ascenda catheters were significantly less likely to have disconnections (p &lt; 0.001) and obstructions (p = 0.016), and overall were less likely to have any catheter-related complications (p = 0.01). Patients with preexisting VP shunts at the time of implantation had a significantly greater mean decrease in MAS scores in both their lower extremities (1.8, p = 0.003) and upper extremities (1.3, p = 0.002) than did patients without shunts. CONCLUSIONS Various complications are associated with ITB therapy, most commonly catheter complications and pseudomeningoceles. There have been fewer catheter complications associated with the newest catheter model, while pseudomeningoceles have become less frequent since the surgical technique was modified to prevent them. VP shunts and G-tubes are not associated with significantly higher complication rates and shunts seem to be associated with greater efficacy of ITB therapy, as represented by a greater mean improvement in MAS scores.

Comparison of the Efficacy of 2 Different Botulinum Toxin Injection Techniques in Gastrocnemius Muscle Spasticity in Hemiplegic Patients: A Randomized Double-Blind Controlled Study

ObjectiveTo compare the efficacy of the innervation zone–targeted injection technique (EUROMUSCULUS/USPRM (Ultrasound Study Group of the International Society of Physical and Rehabilitation Medicine) spasticity approach) and the injection technique along the muscle length. DesignA double-blind randomized controlled trial. SettingDepartment of rehabilitation medicine of a medical center. ParticipantsOne hundred patients with stroke experiencing ankle plantar flexor spasticity. InterventionsIn addition to conventional rehabilitation, eligible patients were randomly assigned to 2 groups. The experimental group was injected with botulinum toxin along the length of the muscle, whereas the control group was injected with the same dose and volume of botulinum toxin 25%-35% proximal to the medial head and 20%-30% proximal to the lateral aspect of the head of the gastrocnemius muscle. Main Outcome MeasuresModified Ashworth scale, modified Tardieu scale, ankle range of motion measurement, and 10-meter walk test were used before and 1 month after injection. ResultsThe study was completed by 60 participants with a mean age of 59.96±12.15 years. Both injection methods were found to be effective on range of motion, spasticity level, ambulation, and walking speed. There was no statistically significant difference between injection methods. ConclusionsBoth injection methods of botulinum toxin A produce similar clinical effects.

Comparative Efficacy of Baclofen and Diazepam in Treating Spasticity Following Acquired Spinal Cord Injuries: A Randomized Controlled Trial

Abstract Introduction: Spasticity is a pervasive and debilitating condition. Anti-spastic medications like Baclofen and Diazepam are most commonly used for spasticity management. Objectives: The study aimed to evaluate and compare the efficacy of Baclofen with that of Diazepam in the management of spasticity following acquired spinal cord injuries. Methods: In this randomised open-label study involving 60 patients, 30 patients received 5 mg of oral Baclofen thrice daily and 30 patients received 5 mg of oral Diazepam thrice daily for the management of spasticity. The extent of spasticity was measured by Modified Ashworth Scale (MAS). The efficacy of these drugs was measured with the mean improvement in the above parameters on days 7, 14, 28, 56 and 90 from the start of pharmacotherapy. Results: Baseline muscle spasticity scores were comparable. At the endpoint, mean improvement in tone of right and left hip flexors (1.43 vs. 0.87), hip adductors (1.30 vs. 0.87), knee flexors (0.80 vs. 0.37), ankle plantar flexors (0.80 vs. 0.37) and ankle dorsiflexors (1.23 vs. 0.93) were significantly higher in Baclofen group (p&lt;0.05), while the tone of right and left hip abductors, hip and knee extensors showed no significant difference among the groups. Conclusion: Baclofen was found to be superior to Diazepam in terms of efficacy, especially for flexor spasticity of lower limbs in acquired spinal cord injuries.

Effect of Dry Needling Plus Static Stretching on Plantar Flexors Spasticity in Chronic Stroke Patients.

Stroke is a leading cause of disability worldwide and is often accompanied by complications such as spasticity. Static stretching (SS) is a common physiotherapy intervention for reducing spasticity, whereas dry needling (DN) is a novel approach. However, the combined effects of DN and SS on spasticity have not been thoroughly investigated. Given the pivotal effect of spasticity on daily activities, mitigating spasticity can significantly contribute to restoring patient independence. This study will explore the impact of DN plus SS on spasticity, alpha motor neuron excitability, overall function, and quality of life in patients with chronic stroke. A double-blind, randomized, sham-controlled trial will be conducted in patients with post-stroke spasticity in the plantar flexor muscles. Twentyeight participants will be randomly assigned to either an intervention or control group. The intervention group will receive DN (60s × 3 days/week; 1 week) plus SS (20 min × 5 days/ week; 1 week). The control group will undergo sham DN (60s × 3 days/week; 1 week) and SS (20 min × 5 days/week; 1 week). DN plus SS or sham DN plus SS. Both groups will be assessed at baseline, immediately post-treatment, and after 1 week of follow-up. Outcome measures will include the Modified Modified Ashworth Scale, H-reflex latency, Hmax/Mmax ratio, active and passive ankle dorsiflexion range of motion, timed up and go test, and the EuroQol questionnaire. Results from this randomized, sham-controlled study will provide evidence for the effectiveness of DN in combination with SS for spasticity. The additional impact of DN in conjunction with SS, a widely used method for reducing muscle tone, remains unclear and warrants investigation. This study, with a high level of evidence, aims to address this knowledge gap.

Efficacy of Dry Needling in Enhancing Hand Function and Reducing Spasticity in MCA Stroke Patients: A Prospective Case Report

Stroke, particularly involving the middle cerebral artery (MCA), often leads to persistent disability, significantly impairing hand function and inducing severe spasticity in the forearm flexors due to complex motor pathway involvement. This case report evaluates the effectiveness of combining dry needling therapy (DNT) with task-oriented training (TOT) in reducing spasticity and improving hand function in a post-MCA stroke patient. A 61-year-old male with right-side hemiplegia following a left MCA stroke, compounded by a history of diabetes, hypertension, and recent kidney stone diagnosis, participated in this study. The patient experienced severe functional limitations due to spasticity (grade 3 on the Modified Ashworth Scale) and scored 31 on the CAHAI-13, indicating significant hand dysfunction. DNT was applied to key forearm muscles (flexor carpi radialis, flexor carpi ulnaris, flexor digitorum superficialis, flexor digitorum profundus, and pronator teres), followed by TOT targeting daily tasks. Post-intervention, the patient demonstrated significant improvements: spasticity was reduced (Modified Ashworth Scale score decreased from grade 3 to grade 2), and muscle hypertonicity, as measured by EMG, was reduced in all targeted muscles. Functional hand use improved markedly, with the CAHAI-13 score increasing from 31 to 45. These improvements led to enhanced independence in daily activities. This case report highlights the clinical relevance of integrating DNT with TOT in stroke rehabilitation. The combined intervention not only reduced spasticity and improved neuromuscular function but also led to meaningful gains in hand function, enhancing the patient’s ability to perform daily activities independently. Given the promising results, this combined approach could serve as a practical and effective strategy for improving motor recovery and functional independence in post-stroke patients. Further studies with larger sample sizes are necessary to confirm these findings and explore the broader application of this approach in clinical practice.

Isokinetic and electromyographic characterization of ankle plantarflexors' hypertonia in people with multiple sclerosis

BackgroundThis study aimed at quantifying ankle plantarflexors’ resistance to passive motion (RPM) by isokinetic dynamometry and muscle activity through surface electromyography (sEMG) in persons with multiple sclerosis (PwMS) with limb stiffness and spasticity. MethodsSlow and fast ankle dorsiflexions (from 5°/s to 210°/s) were imparted passively by an isokinetic dynamometer, and sEMG activity of plantarflexors was recorded at the same time as the square root of the moving average. Based on RPM evaluated at 5°/s, ankles were classified as more- and less-resistant as measured by average peak torque (APT). ResultsMeasurements were obtained bilaterally from 24 PwMS (median EDSS: 5.5) with median Modified Ashworth Scale (MAS) score of 1.75. Compared to the lowest velocity inducing EMG-evident responses (120°/s), RPM increased significantly at 180°/s (+137.8 %; p < 0.0005) and 210°/s (+85.3 %; p < 0.0005) in the less-resistant side, and only at 210°/s (+113.8 %; p < 0.0005) in the more-resistant side. sEMG activity increased significantly and similarly between limbs at increasing velocities. Significant velocity-dependent increases were detected in both limbs, with no difference by side, at 180°/s (+34.5 %; p = 0.005) and 210°/s (+48.4 %; p = 0.004). Regression analyses confirmed side (β=0.542; p < 0.0001) and speed (β=0.238; p < 0.0001) as significant predictors of APT change, but only speed for sEMG (speed: β=0.215; p = 0.019; side: β=0.012; p = 0.893).Bivariate correlations revealed that RPM was associated negatively with MAS and positively with sEMG. ConclusionSpasticity presented bilaterally in PwMS, with different mixed pictures of passive and reflex stiffness, both requiring attention. Combining isokinetics and sEMG allows detecting even subtle, subclinical alterations that can prompt and drive early tailored management.

CLINICAL FEATURES OF MOTOR DEFICIT AND COGNITIVE DISORDERS IN POST-STROKE PATIENTS

The aim of the study – to determine the clinical features of motor deficits and cognitivedisorders in post-stroke patients.Materials and methods. The examination of 39 post-stroke patients included: clinicalneurological, psychodiagnostic methods using the National Institutes of Health StrokeScale (NIHSS), Action Reserch Arm test (ARAT), Modified Ashworth Scale (MAS), MontrealCognitive Assessment Scale (MoCA), Hospital Anxiety and Depression Scale (HADS).Results. Movement disorders with spasticity syndrome of varying severity were diagnosedin all examined patients. Severe and moderate degree of motor dysfunctions of the upperlimbs were revealed in 76.92 % of patients from the 1-st group and remained in 56.41 %of patients from the 2nd group. Violations of muscle tone in the affected limbs variedfrom an increase of a moderate degree to an increase of a mild degree in 74.36 % ofpatients. An increase in cognitive dysfunction, symptoms of anxiety and depression wereobserved in a 12 months after stroke. A higher degree of motor disorders correlated withthe expression of anxiety- depressive disorders.Conclusions. The number of patients with motor deficits of mild and moderate severitydegrees has increased over time. At the same time, the number of patients with moderateand severe degrees of movement disorders has decreased, which correlates with theseverity of anxiety and depression, as well as cognitive dysfunctions.

Efficacy of a Virtual Reality Rehabilitation Protocol Based on Art Therapy in Patients with Stroke: A Single-Blind Randomized Controlled Trial.

Art therapy has a long history of applications in cognitive and motor rehabilitation. More recently, a growing body of scientific literature has highlighted the potential of virtual reality in neurorehabilitation, though it has focused more on the technology itself than on the principles adopted in digital scenarios. This study is a single-blind randomized controlled trial conducted on 40 patients with stroke, comparing conventional therapy (physical therapy for the upper and lower limbs, for posture and balance, cognitive therapy, occupational therapy, speech therapy, and specific therapy for swallowing, bowel, and bladder dysfunctions) to a protocol in which the upper limb physical therapy was substituted with art therapy administered by means of virtual reality exploiting the so-called Michelangelo effect. After 12 sessions, patients in the virtual art therapy group showed a significantly greater improvement in independence in activities of daily living, as assessed by the Barthel Index (interaction of time and group: p = 0.001). Significant differences were also found in terms of upper limb muscle strength (Manual Muscle Test, p < 0.01) and reduction in spasticity (Ashworth scale, p = 0.007) in favor of the experimental group. In the virtual art therapy group, the effectiveness of the intervention was significantly correlated with patient participation (Pittsburgh Rehabilitation Participation Scale: R = 0.41), patient satisfaction (R = 0.60), and the perceived utility of the intervention by the therapist (R = 0.43). These findings support the efficacy of virtual art therapy leveraging the Michelangelo effect. Further studies should also focus on cognitive domains that could benefit from this type of approach.

Safety and potential effects of intrathecal injection of allogeneic human umbilical cord mesenchymal stem cell-derived exosomes in complete subacute spinal cord injury: a first-in-human, single-arm, open-label, phase I clinical trial

ObjectiveNeurological and functional impairments are commonly observed in individuals with spinal cord injury (SCI) due to insufficient regeneration of damaged axons. Exosomes play a crucial role in the paracrine effects of mesenchymal stem cells (MSCs) and have emerged as a promising therapeutic approach for SCI. Thus, this study aimed to evaluate the safety and potential effects of intrathecal administration of allogeneic exosomes derived from human umbilical cord MSCs (HUC-MSCs) in patients with complete subacute SCI.MethodsThis study was a single-arm, open-label, phase I clinical trial with a 12-month follow-up period. HUC-MSCs were extracted from human umbilical cord tissue, and exosomes were isolated via ultracentrifugation. After intrathecal injection, each participant a underwent complete evaluation, including neurological assessment using the American Spinal Injury Association (ASIA) scale, functional assessment using the Spinal Cord Independence Measure (SCIM-III), neurogenic bowel dysfunction (NBD) assessment using the NBD score, modified Ashworth scale (MAS), and lower urinary tract function questionnaire.ResultsNine patients with complete subacute SCI were recruited. The intrathecal injection of allogeneic HUC-MSCs-exosomes was safe and well tolerated. No early or late adverse event (AE) attributable to the study intervention was observed. Significant improvements in ASIA pinprick (P-value = 0.039) and light touch (P-value = 0.038) scores, SCIM III total score (P-value = 0.027), and NBD score (P-value = 0.042) were also observed at 12-month after the injection compared with baseline.ConclusionsThis study demonstrated that intrathecal administration of allogeneic HUC-MSCs-exosomes is safe in patients with subacute SCI. Moreover, it seems that this therapy might be associated with potential clinical and functional improvements in these patients. In this regard, future larger phase II/III clinical trials with adequate power are highly required.Trial registrationIranian Registry of Clinical Trials, IRCT20200502047277N1.

THE EVALUATION OF TOTAL HIP ARTHROPLASTY IN THE MANAGEMENT OF SPASTIC PAINFUL HIP DISLOCATION IN CEREBRAL PALSY

Spasticity used to be considered a contraindication for total hip replacement (THR) procedures. Due to the development of implants as well as surgical skills, THR became an option for the treatment of painful dislocation of the hip joint in patients with spastic plegia. The aim of this study was an evaluation of mid-term results of THR in spastic CP adolescent patients with painful hips with hip joint subluxation or dislocation.In 2014–2022, 18 pts (19 hips) with CP aged 16 to 20 years underwent THR in our department. The mean follow-up was 4 years (range: 1 – 9 years). Results were evaluated using the Gross Motor Function Scale, VAS scale in accordance with the Ashworth scale, types of implants used (dual mobility cup and not dual mobility cup), and radiological assessment (Crowe scale). Complications have been thoroughly analyzed.In 10 pts there has been an improvement in the GMFSC scale average from 1 to 2 points observed after the surgery. All pts have improved in the VAS scale average of 8 points (from 10 to 7). According to the Crowe scale repositioning of preoperative dislocation to primary acetabulum was achieved in all cases. Complications occurred in 4 cases: dislocations of 2 THR with dual mobility cup and 2 THR with non-dual mobility cup requiring revision surgery with good final result. No statistical significance was noted according to the type of cup (Mann-Whitney U Test).The most important risk factor for complications is severe spasticity. We believe, that CP pts with painful hips should be treated using THR. We didn't observe any significant differences between the types of implants.These findings may serve as a basis for the prediction of outcomes of THR treatment in this specific group of pts.Level of evidence: Case-control or retrospective comparative study-Level III

Mechanomyography-Based Metric Scale for Spasticity: A Pilot Descriptive Observational Study.

(1) Background: The Modified Ashworth Scale (MAS) is commonly used clinically to evaluate spasticity, but its qualitative nature introduces subjectivity. We propose a novel metric scale to quantitatively measure spasticity using mechanomyography (MMG) to mitigate these subjective effects. (2) Methods: The flexor and extensor muscles of knee and elbow joints were assessed with the Modified Ashworth Scale (MAS) during the acquisition of mechanomyography (MMG) data. The median absolute amplitude of the MMG signals was utilized as a key descriptor. An algorithm was developed to normalize the MMG signals to a universal gravitational (G) acceleration scale, aligning them with the limits and range of MAS. (3) Results: We evaluated 34 lower and upper limbs from 22 volunteers (average age 39.91 ± 13.77 years) of both genders. Polynomial regression provided the best fit (R2 = 0.987), with negligible differences (mean of 0.001 G) between the MAS and MMG. We established three numerical sets for the median, minimum, and maximum MMG(G) values corresponding to each MAS range, ensuring consistent alignment of the Modified Ashworth levels with our proposed scale. (4) Conclusions: Muscle spasticity can now be quantitatively and semi-automatically evaluated using our algorithm and instrumentation, enhancing the objectivity and reliability of spasticity assessments.

Applied anatomy study and preliminary clinical application of hyper selective neurectomy of triceps branches combined with partial neurotomy of S 2 nerve root to relieve spastic equinus foot

To observe the possibility of hyper selective neurectomy (HSN) of triceps branches combined with partial neurotomy of S 2 nerve root for relieving spastic equinus foot. Anatomical studies were performed on 12 adult cadaveric specimens. The S 2 nerve root and its branches were exposed through the posterior approach. Located the site where S 2 joined the sciatic nerve and measured the distance to the median line and the vertical distance to the posterior superior iliac spine plane, and the S 2 nerve root here was confirmed to have given off branches of the pelvic splanchnic nerve, the pudendal nerve, and the posterior femoral cutaneous nerve. Between February 2023 and November 2023, 4 patients with spastic equinus foot were treated with HSN of muscle branches of soleus, gastrocnemius medial head and lateral head, and cut the branch where S 2 joined the sciatic nerve. There were 3 males and 1 female, the age ranged from 5 to 46 years, with a median of 26 years. The causes included traumatic brain injury in 2 cases, cerebral hemorrhage in 1 case, and cerebral palsy in 1 case. The disease duration ranged from 15 to 84 months, with a median of 40 months. The triceps muscle tone measured by modified Ashworth scale (MAC) before operation was grade 3 in 2 cases and grade 4 in 2 cases. The muscle strength measured by Daniels-Worthingham manual muscle test (MMT) was grade 2 in 1 case, grade 3 in 1 case, and 2 cases could not be accurately measured due to grade 4 muscle tone. The Holden walking function grading was used to evaluate lower limb function and all 4 patients were grade 2. After operation, triceps muscle tone, muscle strength, and lower limb function were evaluated by the above grading. The distance between the location where S 2 joined the sciatic nerve and median line was (5.71±0.53) cm and the vertical distance between the location and posterior superior iliac spine plane was (6.66±0.86) cm. Before joining the sciatic nerve, the S 2 nerve root had given off branches of the pelvic splanchnic nerve, the pudendal nerve, and the posterior femoral cutaneous nerve. All the 4 patients successfully completed the operation, and the follow-up time was 4-13 months, with a median of 7.5 months. At last follow-up, the muscle tone of the patients decreased by 2-3 grades when compared with that before operation, and the muscle strength did not decrease when compared with that before operation. Holden walking function grading improved by 1-2 grades, and there was no postoperative hypoesthesia in the lower limbs. HSN of triceps branches combined with partial neurotomy of S 2 nerve root can relieve spastic equinus foot without damaging other sacral plexus nerves.

The effectiveness of neurorehabilitation in inpatient department

The objective of the study is to evaluate the effectiveness of rehabilitation treatment in patients with neurological pathology in inpatient department.Materials and methods. The study included 101 patients undergoing hospital treatment due to an existing neurological disease. The mean age was 52.41 ± 13.49 years. The condition of each patient upon admission and after the course of inpatient treatment was assessed using special tools – scales, tests, indices and questionnaires, such as the Rehabilitation Routing Scale and the modified Rankin scale, and according to the clinical specifics and needs of rehabilitation treatment – the Ashworth scale, Caprini Scale, Muscle Strength Grading Scale, National Institutes of Health Stroke Scale, HAS-BLED Scale, Berg Scale, Functional Independence Measure, Waterlow Score, Numeric Pain Rating Scale, Frenchay Arm Test, Rivermead Mobility Index, Hauser Index, EQ-5D, Barthel Index. The dynamics of recovery were calculated by comparing scores obtained using special instruments upon admission to rehabilitation treatment and after it.Results. By analyzing the results of the study, a positive dynamic of recovery was established, confirming the effectiveness of an inpatient course of neurorehabilitation, which is expressed in an improvement in the condition of patients when assessed using the designated tools for its objectification.Conclusions. The study confirms the effectiveness of an inpatient course of medical rehabilitation in restoring neurological deficits, increasing the activity of daily living, reducing the degree of social maladjustment and improving the rehabilitation prognosis.
