ABSTRACT
Objective To explore the mechanism of immediate effect regulated by acupuncture on acupoints in patients with migraine without aura(MwoA)during the interictal period.Methods A total of 28 MwoA patients were enrolled and resting-state functional magnetic resonance imaging(rs-fMRI)were performed at baseline and after acupuncture for 30 minutes.Paired t test was used to compare the differences of regional homogeneity(ReHo)and voxel-mirrored homotopic connectivity(VMHC)between two groups.Additionally,the correlation between the changes of rs-fMRI indexes and clinical scores was analyzed.Results In MwoA patients after acupuncture for 30 minutes,the mean regional homogeneity(mReHo)was decreased in the right lingual gyrus and right cere-bellum and was increased in the right middle frontal gyrus,while the z transformation voxel-mirrored homotopic connectivity(zVMHC)was significantly decreased in the bilateral cuneus compared with baseline.There was no significant correlation between imaging data and clinical scales.Conclusion Patients with MwoA after acupuncture for 30 minutes show abnormal ReHo and VMHC in multiple brain regions,which suggest that the mechanism of immediate effect may act through regulating pain-related brain regions.
ABSTRACT
PURPOSE: The ideal performance time of straw phonation exercise, one of the semi-occluded vocal tract exercise types, in which optimal effects are seen in healthy voices is still unknown. The aim of this study was to investigate the immediate effect of straw phonation exercise in healthy adults after 1, 3, 5, 7, and 10 minutes, considering: acoustic parameters, electroglottographic parameters, auditory-perceptual general voice quality, the participants' self-assessment regarding vocal effort, and laryngeal discomfort during exercise. METHODS: This study included 69 participants (35 women, 34 men) with a healthy voice. Participants performed the exercise with straw for a total of 10 minutes. The data were collected before (m0) and immediately after exercises at the first (m1), third (m3), fifth (m5), seventh (m7), and tenth (m10) minutes of performance using sustained emission of vowel /a/ and a sentence. RESULTS: There was an increase in the fundamental frequency at m7 and a decrease in the shimmer from m5 in men. The sound pressure level increased at m5 and m10 in women and from m1 in men. The Acoustic Voice Quality Index score decreased at m5 in men. The mean average closed quotient decreased at m10 in women. Auditory-perceptual general voice quality was optimal at m3 in women and at m5 in men, it deteriorated at m7 in women and at m10 in men. The vocal effort during the exercise increased at m7 in women and at m10 in men. The laryngeal discomfort during the exercise increased for both sexes at m10. CONCLUSIONS: The straw phonation exercise in healthy individuals promoted optimal effects on voice quality after 5 and 7 minutes for men and 3 and 5 minutes for women. Prolongation of the exercise time causes negative effects on voice quality and an increase in vocal effort and laryngeal discomfort presented by the participants.
ABSTRACT
This study aims to evaluate the immediate effect of a robotic ankle-foot orthosis developed in previous studies on a foot drop patient. The difference with previous research on AFO evaluation is that this research used a setting based on the patient's request. The robotic AFO locked the foot position on zero radians during the foot flat until the push-off but generates dorsiflexion with a constant velocity in the swing phase to clear the foot drop. A kinematic and spatiotemporal parameter was observed using the sensors available on the robotic AFO. The robotic successfully assisted the foot drop (positive ankle position of 21.77 degrees during the swing phase and initial contact) with good repeatability (σ2 = 0.001). An interview has also conducted to investigate the qualitative response of the patient. The interview result reveals not only the usefulness of the robotic AFO in assisting the foot drop but also some improvement notes for future studies. For instance, the necessary improvement of weight and balance and employing ankle velocity references for controlling the walking gait throughout the whole gait cycle.

While the energizing effect of light has been known since the early years of light therapy, its reliable detection using objective measures is still not well-established. This review aims to ascertain the immediate energizing effect of light and determine its best indicators. Sixty-four articles published before July 2022 were included in the review. The articles described 72 (sub-)studies performed in healthy individuals. Fourteen measures were analyzed. The analysis showed that light causes an energizing effect that can be best documented by measuring core (rectal) body temperature: the proportion of the studies revealing increasing, unchanging, and decreasing rectal temperature was 13/6/1. The second most suitable indicator was heart rate (10/22/1), which showed concordant changes with rectal temperature (a trend, seven mutual studies). There is no evidence from the reviewed articles that oxygen consumption, skin conductance, blood pressure, heart rate variability, non-rectal inner temperature (combined digestive, tympanic, and oral), skin temperature, or cortisol levels can provide light effect detection. Four other measures were found to be unsuitable as well but with less certainty due to the low number of studies (≤3): skin blood flow, noradrenaline, salivary alpha-amylase, and thyroid-stimulating hormone levels. On the other hand, light exposure had a noticeable effect on sympathetic nerve activity measured using microneurography; however, this measure can be accepted as a marker only tentatively as it was employed in a single study. The analysis took into account three factors-study limitation in design/analysis, use of light in day- or nighttime, and relative brightness of the light stimulus-that were found to significantly influence some of the analyzed variables. The review indicates that the energizing effect of light in humans can be reliably detected using rectal temperature and heart rate.
ABSTRACT
Oral administration of a low dose of lactulose increases the abundance of genus Bifidobacterium in the large intestine; however, the details of the daily variation in Bifidobacterium have not been researched. To observe how the intestinal microbiota, including Bifidobacterium, change, especially immediately after the initiation of ingestion, we conducted a randomised, placebo-controlled, double-blind crossover study of ingestion of 4 g lactulose/day for 2 weeks in 36 healthy Japanese (including males and females). The primary outcome was the percentage of Bifidobacterium in the faecal bacteria. In the lactulose-treatment group, the percentage of Bifidobacterium was already significantly higher 2 days after starting lactulose ingestion than in the placebo group (20.5 ± 1.2% vs. 17.1 ± 1.2%, p = 0.021). Significant differences were maintained, gradually widening, until the end of the 2-week intervention period. There were significant increases in the percentage and the number of Bifidobacterium with ingestion of 4 g lactulose/day for 2 weeks, but no significant changes in the beta diversity of the intestinal microbiota between lactulose and placebo ingestion. The percentage of Bifidobacterium in the faecal bacteria returned to its original level within a week of the end of intervention with lactulose.
ABSTRACT
BACKGROUND: The use of digital interventions can be accurately monitored via log files. However, monitoring engagement with intervention goals or enactment of the actual behaviors targeted by the intervention is more difficult and is usually evaluated based on pre-post measurements in a controlled trial. OBJECTIVE: The objective of this paper is to evaluate if engaging with 2 digital intervention modules focusing on (1) physical activity goals and action plans and (2) coping with barriers has immediate effects on the actual physical activity behavior. METHODS: The NoHoW Toolkit (TK), a digital intervention developed to support long-term weight loss maintenance, was evaluated in a 2 x 2 factorial randomized controlled trial. The TK contained various modules based on behavioral self-regulation and motivation theories, as well as contextual emotion regulation approaches, and involved continuous tracking of weight and physical activity through connected commercial devices (Fitbit Aria and Charge 2). Of the 4 trial arms, 2 had access to 2 modules directly targeting physical activity: a module for goal setting and action planning (Goal) and a module for identifying barriers and coping planning (Barriers). Module visits and completion were determined based on TK log files and time spent in the module web page. Seven physical activity metrics (steps; activity; energy expenditure; fairly active, very active and total active minutes; and distance) were compared before and after visiting and completing the modules to examine whether the modules had immediate or sustained effects on physical activity. Immediate effect was determined based on 7-day windows before and after the visit, and sustained effects were evaluated for 1 to 8 weeks after module completion. RESULTS: Out of the 811 participants, 498 (61.4%) visited the Goal module and 406 (50.1%) visited the Barriers module. The Barriers module had an immediate effect on very active and total active minutes (very active minutes: before median 24.2, IQR 10.4-43.0 vs after median 24.9, IQR 10.0-46.3; P=.047; total active minutes: before median 45.1, IQR 22.9-74.9 vs after median 46.9, IQR 22.4-78.4; P=.03). The differences were larger when only completed Barriers modules were considered. The Barriers module completion was also associated with sustained effects in fairly active and total active minutes for most of the 8 weeks following module completion and for 3 weeks in very active minutes. CONCLUSIONS: The Barriers module had small, significant, immediate, and sustained effects on active minutes measured by a wrist-worn activity tracker. Future interventions should pay attention to assessing barriers and planning coping mechanisms to overcome them.

Murata S, Koike Y, Kasukawa Y, Saito K, Okada K, Kudo D, Shimada Y, Miyakoshi N. Contralaterally controlled functional electrical stimulation immediately improves hand function. Jpn J Compr Rehabil Sci 2022; 13: 26-30. Objective: The purpose of this study was to investigate the immediate effects of contralaterally controlled functional electrical stimulation (CCFES) on upper limb function in stroke patients. Methods: CCFES and mirror therapy (MT) exercises were conducted for 13 stroke patients at least 4 weeks post-onset. A sufficient interval of at least 24 hours was left between the two types of rehabilitation exercises. Before treatment and immediately after each training session, grip strength, Fugl-Meyer Assessment for Upper Extremity (FMA-UE) score and FMA-UE subscores for the shoulder/elbow/forearm, wrist, hand, and coordination were evaluated. Results: Grip strength, FMA-UE and FMA-UE shoulder/elbow/forearm, wrist, and coordination did not differ significantly after CCFES and MT compared to before therapy. FMA-UE hand did not change significantly after MT compared to before therapy, but it improved significantly after CCFES (p = 0.013). Conclusion: CCFES for the upper extremities immediately improves hand function and may be effective in maintaining and improving patients' motivation for rehabilitation treatment.
ABSTRACT
Background: Hand spasticity after stroke influences the rehabilitation of hand function. Immediate and effective relief of spasticity potentially creates conditions for later rehabilitation training, which has far-reaching significance in the smooth transition of patients to the recovery period. Objective: To evaluate the immediate effect of dry needling (DN) at myofascial trigger point on hand spasticity in stroke patients. Methods: This was a prospective, evaluator blind, multicenter, randomized controlled study. A total of 210 participants were randomly divided into DN group (DN, N = 70), sham dry needling group (SDN, N = 70), and control group (N = 70). Participants in the DN group were treated with DN at myofascial trigger point five times (30 min each time) every week for 4 weeks. Subjects in the SDN group were manipulated the same way as in the DN group, except that the acupuncture site was located in the area adjacent to the myofascial trigger point, which constituted a SDN. Routine rehabilitation treatment was performed for participants in the two groups and in the control group. The primary evaluation index was the immediate effect of hand spasticity relief. Secondary evaluation indicators included the cumulative effect of hand spasticity relief from baseline to week 4, and the changes in flexion angles of the wrist, thumb, and fingers 2-5 in the rest position before, immediately after, and 4 weeks after intervention. Results: The immediate effective rate of spasticity relief (thumb, fingers 2-5, and wrist) of patients with different degrees of spasticity in the DN group was higher than that in the control and SDN groups (thumb, χ2 = 55.833, P < 0.001; fingers 2-5, χ2 = 68.096, P < 0.001; wrist, χ2 = 49.180, P < 0.001) (P < 0.05). The effective rate of spasticity relief from baseline to 4 weeks in the DN group exceeded that in the control group and SDN groups (thumb, χ2 = 8.806, P = 0.012; fingers 2-5, χ2 = 8.087, P = 0.018; and wrist, χ2 = 8.653, P = 0.013) (P < 0.05). No difference in immediate and cumulative effect was found between the control group and SDN group. The change of joints flexion angles in resting position before and after each treatment in the DN group was higher than that in the control and SDN groups (P < 0.05), but it was not significantly different between the control group and SDN group. At 4 weeks, although the change in the DN group was higher than that in the control group and SDN group, this difference was not statistically significant (P > 0.05). Conclusion: Dry needling can relieve varying degrees of hand spasticity instantly in post-stroke. Trial Registration: www.chictr.org.cn, ChiCTR1900022379.
ABSTRACT
A trigger point injection (TPI) with local anesthetic in myofascial pain syndrome (MPS) often has the immediate effect of a decrease in pain. It is unknown whether the immediate effect of a decrease in pain affects the subsequent course of pain. It is also unknown whether expectations of a decrease in pain mediate such effects. We aimed to clarify how the effect of a decrease in pain immediately after TPI with local anesthetic affected the subsequent course of pain, and whether it increased expectations of a decrease in pain. This was a prospective, single-center, observational clinical trial. Patients with incurable cancer who visited the palliative care department and received TPI with local anesthetic for MPS were prospectively examined. We evaluated whether the immediate effect of a TPI with local anesthetic affects the subsequent course of pain in MPS by setting expectations as a mediator, using path analysis. From 2018 to 2020, 205 patients with incurable cancer received TPI for MPS. Of these, 58.1% of patients reported an immediate effect of decreased pain. Compared with the non-immediate effect group, the immediate effect group had higher expectations of a decrease in pain, and the higher expectation was maintained at 7 days (p < 0.001). The percentage of patients with pain reduction at 7 days after TPI was 88.2% in the immediate effect group and 39.5% in the non-immediate effect group (p < 0.001). The immediate effect of decreased pain had the greatest influence on pain reduction at 7 days, both directly (ß = 0.194) and indirectly through increased expectations (ß = 0.293), as revealed by path analysis. The effect of a decrease in pain immediately after TPI with local anesthetic affected the subsequent course of MPS pain in patients with incurable cancer by setting expectations as a mediator. There were limitations to the discussion of these findings because this was an observational study.
ABSTRACT
Cupping therapy has been popular in elite athletes in recent years. However, the effect of cupping therapy on reducing muscle fatigue has not been investigated. The purpose of this study was to investigate the immediate and delayed effects of cupping therapy on reducing biceps brachii fatigue during biceps curls. Twelve healthy untrained participants were recruited for this repeated-measures study. Cupping therapy (-300 mmHg pressure for 5 min) and sham control (no negative pressure for 5 min) were applied after biceps fatigue induced by performing repeated biceps curls at 75% of the 10 repetitions of maximum of the non-dominant hand. Surface electromyography (EMG) with spectral analyses [mean frequency (MNF), median frequency (MDF), and spectral moments ratio (SMR)] were used to assess muscle fatigue during the fatigue task. EMG signals during the first 10 repetitions and the last 10 repetitions of biceps curls were used to assess neuromuscular fatigue. There were significant decreases in MNF and MDF and a significant increase in SMR immediately and 24 h after the sham control (no intervention). When comparing the MNF, MDF, and SMR after cupping therapy to the sham control, there was no significant immediate effect on reducing muscle fatigue. However, there was a significant delayed effect on improving recovery following fatigue for the cupping therapy compared to the sham control (MNF changes: sham 0.87 ± 0.02 vs. cupping 0.91 ± 0.02, p < 0.05; MDF changes sham: 0.85 ± 0.03 vs. cupping: 0.91 ± 0.02, p < 0.05; SMR changes: sham 1.89 ± 0.15 vs. cupping 1.58 ± 0.13, p < 0.05). The findings of this study demonstrate that there is a time effect of cupping therapy for reducing muscle fatigue. Cupping therapy is effective on reducing biceps brachii muscle fatigue after 24 h.
ABSTRACT
BACKGROUND: Low back pain (LBP) is a common musculoskeletal problem, which commonly affects balance. Sustained natural apophyseal glide (SNAG) is a successful treatment approach for LPB. However, its influence on balance problems has not been studied before. OBJECTIVE: To investigate the immediate effect of SNAG on postural stability and pain in individuals with flexion-dominant chronic low back pain (FCLBP). METHODS: Randomized placebo-controlled trial in which 64 participants with FCLBP were randomly allocated into two groups (SNAG and sham). SNAG group (n= 32) received central lumbar SNAG on the symptomatic lumbar level(s). Sham group (n= 32) received sham SNAG. The outcome measures were postural stability indices; overall stability index (OSI), anteroposterior stability index (APSI), and mediolateral stability index (MLSI) in addition to pain intensity. Outcomes were assessed using the Biodex Balance System and visual analog scale respectively. Measures were taken before and immediately after interventions. RESULTS: There were statistical significance and high effect size (ES) in favor of the SNAG group regarding OSI, APSI, and pain (p< 0.01, cohen's d ES =1.3, 1.4, 1.1 respectively). MLSI showed moderate ES (cohen's d= 0.7) but did not reach a statistically significant level (p= 0.05). CONCLUSION: Lumbar SNAG produces an immediate improvement in postural stability and pain in individuals with FCLBP.

The immediate and the late effects of inhaled Paraquat (PQ) on systemic and lung inflammation and oxidative stress were investigated. Rats were exposed to saline (control group) and two doses of inhaled PQ (27 and 54 mg/m3) and studied variables were measured: 1) one day after the end of PQ exposure as "immediate condition", 2) 16 days after the end of PQ exposure as "late condition". Total and differential white blood cells (WBC) counts, lipid peroxidation and nitrite were increased but thiol, superoxide dismutase and catalase in the blood and BALF as well as methacholine EC50 was reduced in both conditions in the animals exposed to PQ compared to control groups (p < 0. 05 to p < 0.001). Most studied parameters in the immediate condition were significantly higher than the late condition (p < 0.05 to p < 0.001). Systemic and lung inflammation and oxidative stress due to inhaled PQ in both the immediate and the late conditions were shown. Although most measured parameters in the immediate condition were higher, all variables were significantly different with the control group even in late condition, indicating a long-term effect of inhaled PQ toxicity, which may help in a more effective treatment of PQ poising in the future.

External visual cueing is a well-known means to target freezing of gait (FOG) in Parkinson's disease patients. Holocue is a wearable visual cueing application that allows the HoloLens 1 mixed-reality headset to present on-demand patient-tailored action-relevant 2D and 3D holographic visual cues in free-living environments. The aim of this study involving 24 Parkinson's disease patients with dopaminergic "ON state" FOG was two-fold. First, to explore unfamiliarity and habituation effects associated with wearing the HoloLens on FOG. Second, to evaluate the potential immediate effect of Holocue on alleviating FOG in the home environment. Three sessions were conducted to examine (1) the effect of wearing the unfamiliar HoloLens on FOG by comparing walking with and without the HoloLens, (2) habituation effects to wearing the HoloLens by comparing FOG while walking with HoloLens over sessions, and (3) the potential immediate effect of Holocue on FOG by comparing walking with HoloLens with and without Holocue. Wearing the HoloLens (without Holocue) did significantly increase the number and duration of FOG episodes, but this unfamiliarity effect disappeared with habituation over sessions. This not only emphasizes the need for sufficient habituation to unfamiliar devices, but also testifies to the need for research designs with appropriate control conditions when examining effects of unfamiliar wearable cueing devices. Holocue had overall no immediate effect on FOG, although objective and subjective benefits were observed for some individuals, most notably those with long and/or many FOG episodes. Our participants raised valuable opportunities to improve Holocue and confirmed our assumptions about current and anticipated future design choices, which supports ongoing Holocue development for and with end users.
ABSTRACT
Visual-motor illusion (VMI) is to evoke a kinesthetic sensation by viewing images of oneself performing physical exercise while the body is at rest. Previous studies demonstrated that VMI activates the motor association brain areas; however, it is unclear whether VMI immediately alters the resting-state functional connectivity (RSFC). This study is aimed to verify whether the VMI induction changed the RSFC using functional near-infrared spectroscopy (fNIRS). The right hands of 13 healthy adults underwent illusion and observation conditions for 20 min each. Before and after each condition, RSFC was measured using fNIRS. After each condition, degree of kinesthetic illusion and a sense of body ownership measured using the Likert scale. Our results indicated that, compared with the observation condition, the degree of kinesthetic illusion and the sense of body ownership were significantly higher after the illusion condition. Compared with the observation condition, RSFC after the illusion condition significantly increased brain areas associated with kinesthetic illusion, a sense of body ownership, and motor execution. In conclusion, RSFC has become a biomarker that shows changes in brain function occurring due to VMI. VMI may be applied to the treatment of patients with stroke or orthopedic diseases.

OBJECTIVE: To compare the immediate effect of acupuncture and moxibustion at Guanyuan (CV 4) and Zusanli (ST 36) on heart rate variability index in patients with qi deficiency syndrome. METHODS: Ninety patients with qi deficiency syndrome were randomly divided into an acupuncture group, a moxibustion group and a blank group, 30 patients in each group. The patients in the acupuncture group were treated with acupuncture at Guanyuan (CV 4) and Zusanli (ST 36) for 15 min; acupuncture was given once. The patients in the moxibustion group were treated with moxibustion with identical acupoints and treatment duration. The patients in the blank group received no intervention. The symptom scores of qi deficiency syndrome in each group before and after treatment were recorded. The average heart rate and index of heart rate variability including total power, low frequency (LF), high frequency (HF) and logarithm of LF/HF (log LF/HF) were tested 5 min before treatment, 5 min, 10 min, 15 min into treatment, and 5 min after treatment. RESULTS: The symptom scores of qi deficiency syndrome were reduced in the acupuncture group and moxibustion group after treatment (P<0.05). Compared before treatment, in the acupuncture group, the HF was increased 5 min into treatment (P<0.05), but was reduced 15 min into treatment and 5 min after treatment (P<0.05, P<0.01). The log LF/HF was increased 5 min and 10 min into treatment and 5 min after treatment (P<0.01). The difference of average heart rate between 5 min before treatment and 5 min after treatment in the acupuncture group was higher than that in the moxibustion group and blank group (P<0.05), and the difference of log LF/HF was higher than that in the moxibustion group and blank group (P<0.05, P<0.01). CONCLUSION: Acupuncture and moxibustion has immediate effects on heart rate variability in patients with qi deficiency syndrome, and the effect of acupuncture is superior to moxibustion, which may be related to the benign regulation of acupuncture on autonomic nervous system.

OBJECTIVE: To observe the effect on swallowing function in patients with post-stroke dysphagia treated with nape cluster acupuncture and the immediate effect of acupuncture at Fengchi (GB 20). METHODS: A total of 60 patients with post-stroke dysphagia were randomized into an observation group and a control group, 30 cases in each one.On the basis of conventional western medication treatment, swallowing function training was applied in the control group, once a day.On the base of the treatment as the control group, nape cluster acupuncture was applied at Fengchi (GB 20), Tianzhu (BL 10), Wangu (GB 12), Lianquan (CV 23), Panglianquan (Extra), Jinjin (EX-HN 12) and Yuye (EX-HN 13) in the observation group, once a day. Additionally, pricking blood was applied at Jinjin (EX-HN 12) and Yuye (EX-HN 13), 2 times a week. The treatment was given 30 min each time, a week as one course and 4 courses were required. Before and after treatment, the standardized swallowing assessment (SSA) score and video fluoroscopic swallowing study (VFSS) score were compared in the two groups. The ultrasonic diagnostic device of swallowing and surface electromyography were used to observe the immediate effect on swallowing related muscles of acupuncture at Fengchi (GB 20). RESULTS: Compared before treatment, the SSA scores were reduced after treatment in the two groups (P<0.05), and the change of the observation group was larger than the control group (P<0.05). Compared before treatment, the VFSS scores were increased after treatment in the two groups (P<0.05), and the change of the observation group was larger than the control group (P<0.05). Acupuncture at Fengchi (GB 20) immediately increased the amplitude of submental muscles and infrahyoid muscles in the observation group (P<0.05), the geniohyoid muscle movement time was reduced and geniohyoid muscle displacement was increased (P<0.05). CONCLUSION: On the base of the routine treatment, nape cluster acupuncture could improve swallowing function in patients with post-stroke dysphagia. Acupuncture at Fengchi (GB 20) could immediately affect swallowing related muscles, improve muscle amplitude and reduce swallowing time.

The purpose of this study was to investigate whether and how vagus nerve stimulation (VNS) reduces the epileptogenic activity in the bilateral cerebral cortex in patients with intractable epilepsy. We analyzed the electrocorticograms (ECoGs) of five patients who underwent callosotomy due to intractable epilepsy even after VNS implantation. We recorded ECoGs and analyzed power spectrum in both VNS OFF and ON phases. We counted the number of spikes and electrodes with epileptic spikes, distinguishing unilaterally and bilaterally hemispherically spread spikes as synchronousness of the epileptic spikes in both VNS OFF and ON phases. There were 24.80 ± 35.55 and 7.20 ± 9.93 unilaterally spread spikes in the VNS OFF and ON phases, respectively (P = 0.157), and 35.8 ± 29.21 and 10.6 ± 13.50 bilaterally spread spikes in the VNS OFF and ON phases, respectively (P = 0.027). The number of electrodes with unilaterally and bilaterally spread spikes in the VNS OFF and ON phases was 3.84 ± 2.13 and 3.59 ± 1.82 (P = 0.415), and 8.20 ± 3.56 and 6.89 ± 2.89 (P = 0.026), respectively. The ECoG background power spectra recordings in the VNS OFF and ON phases were also analyzed. The spectral power tended to be greater in the high-frequency band at VNS ON phase than OFF phase. This study showed the reduction of epileptogenic spikes and spread areas of the spikes by VNS as immediate effects, electrophysiologically.

PURPOSE: Early intervention is effective for developing motor ability and preventing contractures and deformities in patients with cerebral palsy (CP). Gait training using the newly developed Hybrid Assistive Limb (HAL) shows promise as an intervention to prevent deterioration in walking ability and deformities in pediatric CP patients. The purpose of this pilot study was to examine the safety and immediate effects on walking ability after gait training using the HAL in pediatric CP patients. METHODS: Nineteen patients (six females, 13 males; mean age 8.5â¯years; mean height 120.5â¯cm; mean weight 23.2â¯kg) were enrolled. The Gross Motor Functional Classification Scale level was I in two patients, II in two, III in eight, and IV in seven. The HAL was used for a single session of gait training. The primary outcome was safety of the HAL for use in pediatric CP patients. The secondary outcome was the immediate effect after gait training with HAL, evaluated by passive range of motion (ROM) and gait parameters, including gait speed (m/s), step length (cm), and cadence (step/min). RESULTS: All 19 patients were able to carry out the gait training without any severe adverse events. Significant improvements were observed for mean internal/external rotation and abduction angles of the hip joint, and ankle dorsiflexion angles (nâ¯=â¯19). Significant improvements were observed for mean gait speed and step length based on expansion of the hip flexion-extension range (nâ¯=â¯11). CONCLUSION: Gait training using the HAL is safe and can produce immediate improvements in ROM and walking ability in pediatric patients with CP.

Objective: Various psychosocial factors were exploratively investigated in order to specify items that influence on immediate effect of acupuncture among patients with chronic low back pain. Method: Fifty-six outpatients with initial diagnosis of chronic low back pain, visiting the Acupuncture Department of Center for Integrative Medicine, Tsukuba University of Technology between August to December 2019 were included in the study. The baseline lumbar pain intensity of the patients evaluated using the Visual Analogue Scale (VAS) was >30 mm. Psychological scales viz., Pain Catastrophizing Scale (PCS), Hospital Anxiety and Depression Scale (HADS), Pain Self-Efficacy Questionnaire (PSEQ), social factors (cohabitation family situation, final education, social participation status), lumbar dysfunction, and impression on acupuncture were recorded using a self-administered questionnaire during the first visit. Patients showing decreased VAS scale (≦30 mm) after the first acupuncture treatment as well as self-recognition of improvement in pain were classified as “high responders” while the others were treated as “low responders”. Physical and psychosocial factors were exploratively compared between high and low responders and logistic regression analysis of the two groups was performed using a dichotomous dependent variable. Results and Discussion: The number of high and low responders were 22 and 34, respectively. On comparing these groups exploratively, positive (P=0.001) and negative (P=0.004) impression on acupuncture were the only items that showed statistical significance. Among items used as covariates in the logistic regression analysis, the PCS (OR: 0.886 (95% CI: 0.808 to 0.971); P=0.010), positive impression on acupuncture (OR: 5.085 (95% CI: 1.724 to 15.002); P=0.003), and number of people living together (OR: 0.355 (95% CI: 0.149 to 0.844); P=0.019) showed statistical significance. Hence, it may be suggested that psychosocial factors influence the immediate effect of acupuncture among patients with chronic low back pain.
ABSTRACT
OBJECTIVE@#To observe the effect on swallowing function in patients with post-stroke dysphagia treated with nape cluster acupuncture and the immediate effect of acupuncture at Fengchi (GB 20).@*METHODS@#A total of 60 patients with post-stroke dysphagia were randomized into an observation group and a control group, 30 cases in each one.On the basis of conventional western medication treatment, swallowing function training was applied in the control group, once a day.On the base of the treatment as the control group, nape cluster acupuncture was applied at Fengchi (GB 20), Tianzhu (BL 10), Wangu (GB 12), Lianquan (CV 23), Panglianquan (Extra), Jinjin (EX-HN 12) and Yuye (EX-HN 13) in the observation group, once a day. Additionally, pricking blood was applied at Jinjin (EX-HN 12) and Yuye (EX-HN 13), 2 times a week. The treatment was given 30 min each time, a week as one course and 4 courses were required. Before and after treatment, the standardized swallowing assessment (SSA) score and video fluoroscopic swallowing study (VFSS) score were compared in the two groups. The ultrasonic diagnostic device of swallowing and surface electromyography were used to observe the immediate effect on swallowing related muscles of acupuncture at Fengchi (GB 20).@*RESULTS@#Compared before treatment, the SSA scores were reduced after treatment in the two groups (<0.05), and the change of the observation group was larger than the control group (<0.05). Compared before treatment, the VFSS scores were increased after treatment in the two groups (<0.05), and the change of the observation group was larger than the control group (<0.05). Acupuncture at Fengchi (GB 20) immediately increased the amplitude of submental muscles and infrahyoid muscles in the observation group (<0.05), the geniohyoid muscle movement time was reduced and geniohyoid muscle displacement was increased (<0.05).@*CONCLUSION@#On the base of the routine treatment, nape cluster acupuncture could improve swallowing function in patients with post-stroke dysphagia. Acupuncture at Fengchi (GB 20) could immediately affect swallowing related muscles, improve muscle amplitude and reduce swallowing time.
