Application of a Dual Upper Limb Task-Oriented Robotic System for the Functional Recovery of the Upper Limb in Stroke Patients.

Highly repetitive and task-oriented training has been shown to promote the recovery of limb function in stroke patients. Additionally, bilateral arm training can help stroke survivors regain their upper limb function and improve their daily activities. The dual upper limb task-oriented robotic system is designed to assist the healthy side of the stroke patient in driving the affected side to perform bilateral arm training through the use of a robotic device. It can also guide the patient in carrying out dual upper limb coordinated movements and engage them in a task-oriented virtual game using force feedback and human-computer interaction technology. This study aimed to assess the efficacy of the system in enhancing upper limb function and activities of daily living in stroke patients. The assessment methods used included motor evoked potential (MEP), functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK), Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE), and modified Barthel index (MBI). The results of the study indicate that the dual upper limb task-oriented robotic system can significantly improve the corticospinal pathway, upper limb function, and activities of daily living in stroke patients after 6 weeks of treatment. This system can serve as an effective adjunct to upper limb functional rehabilitation in stroke survivors, reducing the dependence on rehabilitation therapists. In conclusion, the dual upper limb task-oriented robotic system provides a new strategy for post-stroke limb functional rehabilitation and holds great potential for application, as it offers certain social and financial benefits.

Elastic resistance exercise effects in gait kinematic characteristics and lower limb functional rehabilitation

Background: Elastic resistance exercise is a popular type of exercise. Elastic bands are widely used in pre-competition preparation and for sports performance improvement. Purpose: The purpose of the present review is the study of the effect using exercise with elastic resistance bands, in walking kinematics and functionality level after surgical repair of low extremity degenerative diseases. Methodology: A systematic literature review was carried out at Advanced Scholar Google, Cochrane, PubMed and Embase databases, a chronological range from 1999 to 2022. Terms used in the search were as follows: “elastic resistance exercise”, “elastic resistance bands”, “Thera-band”, “arthropathy”, “hip replacement”. Results: Systematic elastic resistance exercise in the frame of a rehabilitation program lasting 8-12 weeks, provides results comparable to an isotonic exercise program, using free weights or constant resistance devices. Elastic resistance bands are commonly used for increasing muscle strength and range of motion and also for static and dynamic balance, walking ability and functionality level improvement. Important benefits observed in metabolic biochemical health biomarkers in the elderly.

Using mechanistic knowledge to appraise contemporary approaches to the rehabilitation of upper limb function following stroke.

It is a paradox of neurological rehabilitation that, in an era in which preclinical models have produced significant advances in our mechanistic understanding of neural plasticity, there is inadequate support for many therapies recommended for use in clinical practice. When the goal is to estimate the probability that a specific form of therapy will have a positive clinical effect, the integration of mechanistic knowledge (concerning 'the structure or way of working of the parts in a natural system') may improve the quality of inference. This is illustrated by analysis of three contemporary approaches to the rehabilitation of lateralized dysfunction affecting people living with stroke: constraint-induced movement therapy; mental practice; and mirror therapy. Damage to 'cross-road' regions of the structural (white matter) brain connectome generates deficits that span multiple domains (motor, language, attention and verbal/spatial memory). The structural integrity of these regions determines not only the initial functional status, but also the response to therapy. As structural disconnection constrains the recovery of functional capability, 'disconnectome' modelling provides a basis for personalized prognosis and precision rehabilitation. It is now feasible to refer a lesion delineated using a standard clinical scan to a (dis)connectivity atlas derived from the brains of other stroke survivors. As the individual disconnection pattern thus obtained suggests the functional domains most likely be compromised, a therapeutic regimen can be tailored accordingly. Stroke is a complex disorder that burdens individuals with distinct constellations of brain damage. Mechanistic knowledge is indispensable when seeking to ameliorate the behavioural impairments to which such damage gives rise.

Repeated Transcranial Magnetic Stimulation Combined with Action Observation Training in Children with Spastic Cerebral Palsy.

This study presents the results of a randomized controlled trial utilizing a 2 x 2 factorial design, comparing the effects of repeated transcranial magnetic stimulation (rTMS) and action observation training (AOT) intervention methods on spasticity, balance function, and motor function in children with spastic cerebral palsy (SCP). The study aimed to investigate whether the combination of the two interventions produces greater improvement than either treatment alone or conventional treatment. Subject children in this study, in accordance with the random number table, were randomly divided into four groups: conventional group, rTMS group, AOT group, and combined intervention group. All the children in the four groups received conventional rehabilitation treatment, on the basis of which they were given different therapeutic programs of rehabilitation measures. The conventional group had no other treatment while the rTMS group received rTMS, the AOT group received AOT and the combined intervention group was given a combined intervention of rTMS and AOT. They were trained five days per week for 12 weeks. Changes in scores of spasticity, balance function, walking ability, and gross motor function were assessed at the onset of the training program and upon completion of 12 weeks of treatment. A total of 64 Children with SCP completed the study, and their results were analyzed. The total gross motor function efficiency of 87.50% in the experimental group was significantly higher than that of 25.00% in the conventional group, 62.50% in the rTMS group, and 68.75% in the AOT group. The preliminary results showed that combined intervention of rTMS and AOT could effectively improve the balance function and motor function of children, and the therapeutic effect of the combined intervention was better than that of conventional treatment, rTMS or AOT alone. Finally, clinical efficacy and optimal treatment parameters of the combined intervention were clarified to provide a clinical basis for therapists to conduct lower limb function rehabilitation for children with SCP.

Recovery after ischemic stroke: Effects of FuekFone home-based program on upper limb and cognitive function

ObjectivesThis study aimed to explore the effects of the “FuekFone (F.F.) home-based program” on the upper limb and cognitive function of ischemic stroke patients after discharge. MethodsA single group pre-and post-test design was conducted. A total of 40 patients with recovery after ischemic stroke were recruited from two university hospitals in Thailand. The study was conducted between June 2022 and January 2023. Participants underwent a six-week “F.F. home-based program,” which combined an upper limb and cognitive function rehabilitation device with Android games, including stationary barrel, adventure walk, adventure stroll, sliding barrel, sauce squeeze, and cut objects. Each game has different difficulty levels. Patients can perform corresponding exercises through the games according to their conditions under the guidance of medical staff. The patients played for 24 mins per time, 4 mins each game, three days a week. The second week, let the patients play games for 30 mins per time, 5 mins each game, 3 days a week. Then, in the 3–6 weeks, let the patients play games for 1 h per time, 10 mins each game, 5 days a week. At the pre-and post-intervention, the Thai version of the National Institutes of Health Stroke Scale (NIHSS), the Motor Assessment Scale, and the Montreal Cognitive Assessment (MoCA score) were administered to patients at discharge and at 2, 4, and 6 weeksafter discharge, and the results were compared. ResultsAll participants completed this program. Participants had statistically improved upper limb function (upper arm function score, hand movements score, advanced hand activities score, total Motor Assessment Scale score) and MoCA score at 2, 4, and 6 weeks after discharge (P < 0.001). In the comparison of upper limb function and cognitive function at each of the study times, we found statistically improved upper limb function (upper arm function score, hand movements score, advanced hand activities score, total Motor Assessment Scale score) and MoCA score at 4, and 6 weeks after discharge when compared to after discharge and 2 weeks after discharge, respectively (P < 0.05). ConclusionsContinuing care of patients post-stroke after discharge from hospital, such as F.F. home-based program should be applied at home to enhance upper limb and cognitive function.

Personalized and continuous care intervention affects rehabilitation, living quality, and negative emotions of patients with breast cancer

BACKGROUND Breast cancer is among the most common malignancies worldwide. With progress in treatment methods and levels, the overall survival period has been prolonged, and the demand for quality care has increased. AIM To investigate the effect of individualized and continuous care intervention in patients with breast cancer. METHODS Two hundred patients with breast cancer who received systemic therapy at The First Affiliated Hospital of Hebei North University (January 2021 to July 2023) were retrospectively selected as research participants. Among them, 134 received routine care intervention (routing group) and 66 received personalized and continuous care (intervention group). Self-rating anxiety scale (SAS), self-rating depression scale (SDS), and Functional Assessment of Cancer Therapy-Breast (FACT-B) scores, including limb shoulder joint activity, complication rate, and care satisfaction, were compared between both groups after care. RESULTS SAS and SDS scores were lower in the intervention group than in the routing group at one and three months after care. The total FACT-B scores and five dimensions in the intervention group were higher than those in the routing group at three months of care. The range of motion of shoulder anteflexion, posterior extension, abduction, internal rotation, and external rotation in the intervention group was higher than that in the routing group one month after care. The incidence of postoperative complications was 18.18% lower in the intervention group than in the routing group (34.33%; P &lt;0.05). Satisfaction with care was 90.91% higher in the intervention group than in the routing group (78.36%; P &lt;0.05). CONCLUSION Personalized and continuous care can alleviate negative emotions in patients with breast cancer, quicken rehabilitation of limb function, decrease the incidence of complications, and improve living quality and care satisfaction.

Effect of Early Rehabilitation Exercise on Lower Limb Function and Psychological State After Coronary Artery Bypass Grafting: A Randomized Controlled Trial

Background: While early rehabilitation exercise has been shown to improve cardiopulmonary function and functional outcomes after revascularization in individuals who have undergone coronary artery bypass grafting (CABG), further research is still needed to fully understand the importance of psychological status and limb functional rehabilitation following CABG. Therefore, the purpose of this study was to investigate the effects of early rehabilitation exercise on lower limb function and mental health after coronary artery bypass grafting. Methods: Eighty patients who underwent CABG were randomly divided into a routine exercise group and an early rehabilitation exercise group. The degree of lower limb swelling, the amount of incision complications, the first time the patient got out of bed after the operation, the length of postoperative hospital stay, activity tolerance and postoperative psychological state were compared between the two groups. Results: The incidence of postoperative lower extremity oedema was 30% in the early rehabilitative exercise group as compared to 52.5% in the routine exercise group. Between the two groups, there was a statistically significant difference (p &lt; 0.05) in the incidence of postoperative lower limb edema as well as the amount of swelling in the thighs and ankles on postoperative days 1, 3, and 5. In the routine exercise group, the first time the patients got out of bed was 3.45 ± 1.09 days, and the length of postoperative hospitalization was 12.75 ± 5.06 days. In the early rehabilitation exercise group, the first time the patients got out of bed was 1.93 ± 0.57 days, and the length of postoperative hospitalization was 9.50 ± 2.92 days. There were statistically significant differences in these two indices between the two groups (p &lt; 0.05). The activity tolerance of patients in the routine exercise group was 46.10 ± 19.09 min at 2 months after surgery and 69.88 ± 19.05 min at 3 months after surgery. The activity tolerance of patients in the early rehabilitation exercise group was 56.40 ± 17.42 min at 2 months after surgery and 105 ± 23.04 min at 3 months after surgery, and there was a significant difference in activity tolerance between the two groups at these time points following surgery (p &lt; 0.05). In addition, there were statistically significant differences in the Patient Health Questionnaire-9, Generalized Anxiety Self-Assessment Scale-7 and Pittsburgh Sleep Quality Index scores between the two groups (p &lt; 0.05). Conclusions: Early rehabilitation exercises can promote the recovery of lower limb function after CABG to a certain extent, shorten the postoperative bed rest time and hospital stay, and effectively improve postoperative psychological well-being and sleep quality.

The impact of reminiscent music therapy and robot-assisted rehabilitation on older stroke patients: a protocol for a randomized controlled trial.

Stroke is the main disease that causes the burden of neurological disease, leading to upper limb dysfunction and affecting their self-care abilities. Robot-assisted rehabilitation therapy has been gradually used in the rehabilitation of upper limb function after stroke. However, it would be beneficial to explore auxiliary interventions such as reminiscent music therapy, a combination of music and reminiscent, to relieve negative emotions and post-stroke fatigue and improve rehabilitation outcomes. This protocol aims to evaluate the effectiveness of reminiscent music therapy combined with robot-assisted rehabilitation in older stroke patients. This trial is a single-blind, three-arm randomized controlled trial. Older stroke patients with upper limb dysfunction will be recruited. Participants will be randomly assigned to receive usual rehabilitation treatment and care, usual rehabilitation treatment and care plus robot-assisted rehabilitation and reminiscent music therapy, or usual rehabilitation treatment and care plus robot-assisted rehabilitation. Robot-assisted rehabilitation will be conducted by rehabilitation doctors five times per week for 3 weeks. In experimental group 1, a reminiscent song list will be played for patients. The primary outcome is activities of daily living. All outcomes will be evaluated at baseline and in the week immediately post-intervention. We are conducting the first randomized controlled trial on the effects of reminiscent music therapy combined with robot-assisted rehabilitation in older stroke patients. It is expected that this study, if proven effective in improving the activities of daily living in older stroke patients with upper limb dysfunction, will provide evidence-based rehabilitation strategies for medical staff.Clinical Trial Registration: ChiCTR2200063738.

Exploring the Physiological Effect of taVNS on Upper Limb Functional Rehabilitation

Exploring the Physiological Effect of taVNS on Upper Limb Functional Rehabilitation

Efficacy of brain-computer interfaces on upper extremity motor function rehabilitation after stroke: A systematic review and meta-analysis.

The recovery of upper limb function is crucial to the daily life activities of stroke patients. Brain-computer interface technology may have potential benefits in treating upper limb dysfunction. To systematically evaluate the efficacy of brain-computer interfaces (BCI) in the rehabilitation of upper limb motor function in stroke patients. Six databases up to July 2023 were reviewed according to the PRSIMA guidelines. Randomized controlled trials of BCI-based upper limb functional rehabilitation for stroke patients were selected for meta-analysis by pooling standardized mean difference (SMD) to summarize the evidence. The Cochrane risk of bias tool was used to assess the methodological quality of the included studies. Twenty-five studies were included. The studies showed that BCI had a small effect on the improvement of upper limb function after the intervention. In terms of total duration of training, < 12 hours of training may result in better rehabilitation, but training duration greater than 12 hours suggests a non significant therapeutic effect of BCI training. This meta-analysis suggests that BCI has a slight efficacy in improving upper limb function and has favorable long-term outcomes. In terms of total duration of training, < 12 hours of training may lead to better rehabilitation.

Neuro-Muscular Responses Adaptation to Dynamic Changes in Grip Strength.

Precise control of strength is of significant importance in upper limb functional rehabilitation. Understanding the neuro-muscular response in strength regulation can help optimize the rehabilitation prescriptions and facilitate the relative training process for recovery control. This study aimed to investigate the inherent characteristics of neural-muscular activity during dynamic hand strength adjustment. Four dynamic grip force tracking modes were set by manipulating different magnitude and speed of force variations, and thirteen healthy young individuals took participation in the experiment. Electroencephalography were recorded in the contralateral sensorimotor cortex area, as well as the electromyography from the first dorsal interosseous muscle were collected synchronously. The metrics of the Event-related desynchronization, the electromyography stability index, and the force variation, were used to represent the corresponding cortical neural responses, muscle contraction activities, and the level of strength regulation, respectively; and further neuro-muscular coupling between the sensorimotor cortex and the first dorsal interosseous muscle was investigated by transfer entropy analysis. The results indicated a strong relationship that the increase of force regulation demand would result in a force variation increase as well as a stability reduction in muscle motor unit output. Meanwhile, the intensity of neural response increased in both the α and β frequency bands. As the force regulation demand increased, the strength of bidirectional transfer entropy showed a clear shift from β to the γ frequency band, which facilitate rapid integration of dynamic strength compensation to adapt to motor task changes.

Application of cross-migration theory in limb rehabilitation of stroke patients with hemiplegia.

Stroke is a common cause of neurological dysfunction, often resulting in hemiplegia. Thus, rehabilitation of limb function in stroke patients is an important step towards accelerating recovery and improving quality of life. To investigate whether unilateral strength training in hemiplegic stroke patients could lead to cross-migration, an increase in bilateral muscle strength, and an improvement in lower limb motor function. We randomly divided 120 patients with hemiplegic stroke into two groups: Eexperimental and control groups, with 60 patients in each group. Both groups received routine rehabilitation treatment, while the experimental group additionally received ankle dorsiflexion resistance training on the healthy side for 6 wk. We measured the maximum voluntary contract (MVC), changes in surface electromyography (EMG), and the lower limb motor function using the simplified Fugl Meyer Motor Function Assessment Scale (FMA) before and within 1 wk after training. The FMA score in the experimental group improved significantly compared to both their pre-training score and the control group's post-training score (P < 0.05). The integrated EMG of the anterior tibialis muscle and pulmonary intestine muscle in the experimental group were significantly different after training than before (P < 0.05). Furthermore, the MVC of the anterior tibialis muscle on both the healthy and affected sides and the MVC of the pulmonary intestine muscle on both sides showed significant improvement compared with before training and the control group (P < 0.05). Our findings suggest that ankle dorsiflexion resistance training on the healthy side in hemiplegic stroke patients can increase strength in the opposite tibialis anterior muscle and antagonist's muscle, indicating a cross-migration phenomenon of strength training. Furthermore, this type of training can also improve lower limb motor function, providing a new exercise method for improving early ankle dorsiflexion dysfunction.

Virtual Reality for Upper Limb Rehabilitation in Patients With Obstetric Brachial Palsy: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Obstetric brachial palsy (OBP) is a pathology caused by complications during childbirth because of cervical spine elongation, affecting the motor and sensory innervation of the upper limbs. The most common lesion occurs on the C5 and C6 nerve branches, known as Erb-Duchenne palsy. The least common lesion is when all nerve roots are affected (C5-T1), which has the worst prognosis. Virtual reality (VR) is commonly used in neurological rehabilitation for the evaluation and treatment of physical deficits. This systematic review aims to assess the efficacy of VR in the rehabilitation of upper limb function in patients with OBP. A search was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 guidelines in several scientific databases-PubMed, Web of Science, PEDro, Cochrane, MEDLINE, Scopus, and CINAHL-without language or date restrictions and including articles published up to April 2023. The inclusion criteria were established according to the population, intervention, comparison, outcome, and study (PICOS) design framework: children aged <18 years diagnosed with OBP, VR therapy used in addition to conventional therapy or isolated, VR therapy compared with conventional therapy, outcomes related to OBP rehabilitation therapy, and randomized controlled trials (RCTs). The PEDro scale was used to assess the methodological quality of the RCTs, and the Cochrane Collaboration tool was used to assess the risk of bias. The Review Manager statistical software (version 5.4; The Cochrane Collaboration) was used to conduct the meta-analysis. The results were synthesized through information extraction and presented in tables and forest plots. In total, 5 RCTs were included in this systematic review, with 3 (60%) providing information for the meta-analysis. A total of 138 participants were analyzed. All the studies used semi-immersive or nonimmersive VR systems. The statistical analysis showed no favorable results for all outcomes except for the hand-to-mouth subtest of the Mallet scoring system (functional activity; standardized mean difference -0.97, 95% CI -1.67 to -0.27; P=.007). The evidence for the use of VR therapy for upper limb rehabilitation outcomes in patients with OBP was insufficient to support its efficacy and strongly recommend its use. Nevertheless, scientific literature supports the use of VR technologies for rehabilitation as it provides several advantages, such as enhancing the patient's motivation, providing direct feedback, and focusing the patient's attention during the intervention. Thus, the use of VR for upper limb rehabilitation in patients with OBP is still in its first stages. Small sample sizes; limited long-term analysis; lack of testing of different doses; and absence of International Classification of Functioning, Disability, and Health-related outcomes were present in the included RCTs, so further research is needed to fully understand the potential of VR technologies as a therapeutic approach for patients with OBP.

Home-based virtual reality-enhanced upper limb training system in children with brain injury: a randomized controlled trial.

Rehabilitation of upper limb function can be challenging in children with brain lesion. Recent virtual reality (VR) rehabilitation may be an additional treatment option in pediatric rehabilitation. To assess the feasibility and effectiveness of a home-based VR-enhanced rehabilitation program with wearable multi-inertial measurement unit (IMU) sensors on upper limb functions in children with brain injury. This multicenter single blind randomized controlled trial included 40 children with cerebral palsy (CP) or static brain injury. Subjects were randomized 1:1 to experimental and control group. Both the groups maintained the same therapeutic content and dose of occupational therapy during the intervention period. The experimental group performed additional training at home using the VR-enhanced program for at least 30 min/day, 5 days/week, for 6 weeks. VR training consisted of daily activities or games promoting wrist and forearm articular movements using wearable IMU sensors. The Melbourne Assessment of Unilateral Upper Limb Function-version 2 (MA2), Upper Limb Physician's Rating Scale (ULPRS), Pediatric Evaluation of Disability Inventory-computer adaptive test (PEDI-CAT), computerized 3D motion analysis, and user satisfaction survey were performed. Mann-Whitney U test was used to compare treatment effects between groups, and Friedman and Wilcoxon signed-rank tests were used to compare pre and post intervention. Overall 35 children (15 in VR group and 20 in control group) completed the protocol. In the experimental group, an average VR training time was 855 min. The accuracy of motion measured by MA2, segmental movements by ULPRS, daily living capability and social cognitive function by PEDI-CAT, movement time and shoulder movement pattern by motion analysis showed significant improvements. However, there were no significant differences in any of the functional outcome measures compared to the control group. All the children and parents reported positive experiences. Home-based VR training though it had limited impact on improving upper limb function, it could help improve social cognitive function, movement pattern, and efficiency in children with brain injury and could be an effective means of extending clinical therapy to the home.

Experience of using a virtual reality rehabilitation management platform for breast cancer patients: a qualitative study.

Postoperative rehabilitation of upper limb function is crucial for breast cancer. Therefore, we developed a rehabilitation management platform using virtual reality to improve rehabilitation compliance and effect. The purpose of this research was to understand the user usability experience of breast cancer patients about the postoperative rehabilitation management of upper limb function using virtual reality. A qualitative descriptive research was designed. We used a maximum difference purpose sampling method. According to the inclusion and exclusion criteria, a 3-armor hospital in Changchun was selected for the recruitment. A one-on-one semi-structured interviews were conducted with patients after breast cancer operation. The Colaizzi seven-step analysis method was used to classify data under summarized themes. Twenty patients participated in this semi-structured interview. User experience could be summarized into four themes as follows: 1) experience and feeling after using the virtual reality rehabilitation management platform; 2) factors influencing the use of the virtual reality rehabilitation management platform; 3) willingness to recommend the virtual reality rehabilitation management platform to peers; and 4) suggestions to improve the virtual reality rehabilitation management platform. Breast cancer patients who used the rehabilitation management platform had a good experience, and their recognition and satisfaction were high. The use of the platform is influenced by many factors, and most patients are willing to recommend this platform to their peers. Future studies should be conducted according to patients' feedback and suggestions on how to further optimize and improve the platform.

Electrical nerve stimulation for sensory-neural pathway reconstruction in upper-limb amputees.

The loss of the neural sensory function pathways between the stump limbs and the brain greatly impacts the rehabilitation of limb function and the daily lives of amputees. Non-invasive physical stressors, such as mechanical pressure and transcutaneous electrical nerve stimulation (TENS), could be potential solutions for recovering somatic sensations in amputees. Previous studies have shown that stimulating the residual or regenerated nerves in the stumps of some amputees can produce phantom hand sensations. However, the results are inconclusive due to unstable physiological responses caused by inaccurate stimulus parameters and positions. In this study, we developed an optimal TENS strategy by mapping the distribution of the nerves in the stump skin that elicitsphantom sensations known as a "phantom hand map." We evaluated the effectiveness and stability of the confirmed stimulus configuration in a long-term experiment using single- and multi-stimulus paradigms. Additionally, we evaluated the evoked sensations by recording electroencephalograms (EEG) and analyzing brain activities. The results demonstrated that various types of intuitive sensations for amputees could be stably induced by adjusting TENS frequencies, particularly at 5 and 50 Hz. At these frequencies, 100% stability of sensory types was achieved when the stimuli were applied to two specific locations on the stump skin. Furthermore, at these locations, the stability of sensory positions was 100% across different days. Moreover, the evoked sensations were objectively supported by specific patterns of event-related potentials in brain responses. This study provides an effective method for developing and evaluating physical stressor stimulus strategies, which could play an important role in the somatosensory rehabilitation of amputees and other patients suffering from somatomotor sensory dysfunction. The paradigm developed in this study can provide effective guidelines for stimulus parameters in physical and electrical nerve stimulation treatments for a variety of symptoms related to neurological disorders.

Effect of rTMS intervention on upper limb motor function after stroke: A study based on fNIRS.

Stroke is a disease with a high fatality rate worldwide and a major cause of long-term disability. In the rehabilitation of limb motor function after stroke, the rehabilitation of upper limb function takes a long time and the recovery progress is slow, which seriously affects the patients' self-care ability in daily life. Repeated transcranial magnetic stimulation (rTMS) has been increasingly used to improve limb dysfunction in patients with stroke. However, a standardized reference for selecting a magnetic stimulation regimen is not available. Whether to increase the inhibition of the contralateral hemispheric motor cortex remains controversial. This study has evaluated the effects of different rTMS stimulation programs on upper limb function and corresponding brain functional network characteristics of patients with stroke and sought a new objective standard based on changes in brain network parameters to guide accurate rTMS stimulation programs. Thirty-six patients with stroke were selected and divided into control group and treatment group by number table method, with 18 patients in each group, and 3 patients in the control group were turned out and lost due to changes in disease condition. The treatment group was divided into two groups. TMS1 group was given 1 Hz magnetic stimulation in the M1 region of the contralesional hemisphere +10 Hz magnetic stimulation in the M1 region of the affected hemisphere, and the TMS2 group was given 10 Hz magnetic stimulation in the M1 region of the affected hemisphere. The control group was given false stimulation. The treatment course was once a day for 5 days a week for 4 weeks. The Fugl-Meyer Assessment for upper extremity (FMA-UE) sand near-infrared brain function were collected before treatment, 2 weeks after treatment, and 4 weeks after treatment, and the brain function network was constructed. Changes in brain oxygenated hemoglobin concentration and brain network parameters were analyzed with the recovery of motor function (i.e., increased FMA score). Meanwhile, according to the average increment of brain network parameters, the rTMS stimulation group was divided into two groups with good efficacy and poor efficacy. Network parameters of the two groups before and after rTMS treatment were analyzed statistically. (1) Before treatment, there was no statistical difference in Fugl-Meyer score between the control group and the magnetic stimulation group (p = 0.178).Compared with before treatment, Fugl-Meyer scores of 2 and 4 weeks after treatment were significantly increased in both groups (p <0.001), and FMA scores of 4 weeks after treatment were significantly improved compared with 2 weeks after treatment (p < 0.001). FMA scores increased faster in the magnetic stimulation group at 2 and 4 weeks compared with the control group at the same time point (p <0.001).TMS1 and TMS2 were compared at the same time point, FMA score in TMS2 group increased more significantly after 4 weeks of treatment (p = 0.010). (2) Before treatment, HbO2 content in healthy sensory motor cortex (SMC) area of magnetic stimulation group and control group was higher than that in other region of interest (ROI) area, but there was no significant difference in ROI between the two groups. After 4 weeks of treatment, the HbO2 content in the healthy SMC area was significantly decreased (p < 0.001), while the HbO2 content in the affected SMC area was significantly increased, and the change was more significant in the magnetic stimulation group (p < 0.001). (3) In-depth study found that with the recovery of motor function (FMA upper limb score increase ≥4 points) after magnetic stimulation intervention, brain network parameters were significantly improved. The mean increment of network parameters in TMS1 group and TMS2 group was significantly different (χ 2 = 5.844, p = 0.016). TMS2 group was more advantageous than TMS1 group in improving the mean increment of brain network parameters. (1) The rTMS treatment is beneficial to the recovery of upper limb motor function in stroke patients, and can significantly improve the intensity of brain network connection and reduce the island area. The island area refers to an isolated activated brain area that cannot transmit excitation to other related brain areas. (2) When the node degree of M1_Healthy region less than 0.52, it is suggested to perform promotion therapy only in the affected hemisphere. While the node degree greater than 0.52, and much larger than that in the M1_affected region. it is suggested that both inhibition in the contralesional hemisphere and high-frequency excitatory magnetic stimulation in the affected hemisphere can be performed. (3) In different brain functional network connection states, corresponding adjustment should be made to the treatment plan of rTMS to achieve optimal therapeutic effect and precise rehabilitation treatment.

Effect of whole-body vibration training on the recovery of lower limb function in people with stroke: a systematic review and meta-analysis

Purpose The purpose of this meta-analysis was to systematically evaluate the effects of whole-body vibration training (WBVT) on the recovery of lower limb function in people with stroke. Methods The literature search was made in the electronic databases PubMed, Web of Science, Scopus and Embase electronic databases. Only randomized controlled trials were included. Data extraction, quality assessment and meta-analysis were performed. The search was conducted on September 01, 2022. The data analysis software was RevMan 5.3. Results A total of 13 RCTs were included, including 687 patients. The results showed that compared with the control group, the overall difference in balance function was statistically significant [MD = 4.23, 95% CI 2.21 ∼ 6.26, p < 0.0001]. There was no significant difference in the evaluation indexes of lower limb motor function, including the TUG, 10MWT, 6MWT, and FMA - LE. The overall difference in lower limb muscle spasticity was statistically significant [MD = −0.53, 95% CI −0.81 ∼ 0.26, p = 0.0001]. Conclusions Compared with the control group, using WBVT treatment has a more obvious effect on the recovery of lower limb function and muscle spasticity, and there is no obvious advantage in motor function recovery. IMPLICATIONS FOR REHABILITATION This Systematic Review and meta-analysis of evidence suggest that whole-body vibration training is effective in the rehabilitation of lower limb function in patients with stroke. Whole body vibration training may be a better choice for improving balance and spasm in people with stroke. Currently it is not known which whole-body vibration training model with vibration intensity, stimulus type and duration is most effective and to design more targeted interventions.
