Abnormal prefrontal functional network in adult obstructive sleep apnea: A resting-state fNIRS study.

To assess prefrontal brain network abnormality in adults with obstructive sleep apnea (OSA), resting-state functional near infrared spectroscopy (rs-fNIRS) was used to evaluate 52 subjects, including 27 with OSA and 25 healthy controls (HC). The study found that patients with OSA had a decreased connection edge number, particularly in the connection between the right medial frontal cortex (MFG-R) and other right-hemisphere regions. Graph-based analysis also revealed that patients with OSA had a lower global efficiency, local efficiency, and clustering coefficient than the HC group. Additionally, the study found a significant positive correlation between the Montreal Cognitive Assessment (MoCA) score and both the connection edge number and the graph-based indicators in patients with OSA. These preliminary results suggest that prefrontal rs-fNIRS could be a useful tool for objectively and quantitatively assessing cognitive function impairment in patients with OSA.

Efficacy of High-Frequency Repetitive Transcranial Magnetic Stimulation at 10 Hz in Fibromyalgia: A Systematic Review and Meta-analysis.

OBJECTIVE: The purpose of this review was to systematically assess the effectiveness of 10-Hz repetitive transcranial magnetic stimulation (rTMS) in fibromyalgia. DATA SOURCES: We searched PubMed, Cochrane Library, Embase, Web of Science, and Ovid databases as of November 6, 2021. STUDY SELECTION: The inclusion criteria for this review were randomized controlled trials of 10-Hz rTMS for fibromyalgia, exploring the effects of 10-Hz rTMS on pain, depression, and quality of life in patients with fibromyalgia. DATA EXTRACTION: Data extraction was performed independently by 2 evaluators according to predefined criteria, and the quality of the included literature was assessed using the Cochrane Bias Risk Assessment Tool. The measurement outcomes include visual analog scale, Hamilton Depression Rating Scale, and Fibromyalgia Impact Questionnaire, and so on. DATA SYNTHESIS: A total of 488 articles were screened, and the final 7 selected high-quality articles with 217 patients met our inclusion criteria. Analysis of the results showed that high-frequency transcranial magnetic stimulation at 10 Hz was significantly associated with reduced pain compared with sham stimulation in controls (standardized mean difference [SMD]=-0.72; 95% confidence interval [CI], -1.12 to -0.33; P<.001; I2=46%) and was able to improve quality of life (SMD=-0.70; 95% CI, -1.00 to -0.40; P<.001; I2=15%) but not improve depression (SMD=-0.23; 95% CI, -0.50 to 0.05; P=.11; I2=33%). In addition, a subgroup analysis of pain conducted based on stimulation at the primary motor cortex and dorsolateral prefrontal cortex showed no significant difference (SMD=-0.72; 95% CI, -1.12 to -0.33; P=.10; I2=62%). CONCLUSIONS: Overall, 10-Hz rTMS has a significant effect on analgesia and improved quality of life in patients with FMS but did not improve depression.

Comparison of gait between walking up and down an incline with a walking device in older adults.

To identify the gait differences between cane and rolling walker (RW) use on incline and how these walking devices were received and used, 26 qualified older adults walked randomly on downward and upward with a cane and a RW respectively. With the RW use, downward walking show a faster velocity, higher cadence, less stance time, bigger steps and strides than upward walking (p≤.05); but no differences were seen with cane use. When comparing walking between a RW and a cane, those using a cane had faster velocity, larger step and stride lengths (P≤.01) but only during the upward condition. Incline surface plays a critical role in gait differences when walking with walking device. Geriatric professionals need to know the changes in gait that result from the type of device being used and need to incorporate this knowledge in the education provided to older adults for proper use of a walking device.

Attention Bias to Pain Words Comes Early and Cognitive Load Matters: Evidence from an ERP Study on Experimental Pain.

Attention bias (AB) is a common cognitive challenge for patients with pain. In this study, we tested at what stage AB to pain occurs in participants with experimental pain (EP) and tested whether cognitive load interferes with it. We recruited 40 healthy adults aged 18-27 years, and randomized them into control and EP groups. We sprayed the participants in the EP group with 10% capsaicin paste to mimic acute pain and those in the control group with water, accessing both groups' behavioral results and event-related potential data. We found that high-load tasks had longer response times and lower accuracies than low-load tasks did and that different neural processing of words occurred between the groups. The EP group exhibited AB to pain at an early stage with both attentional avoidance (N1 latency) and facilitated attention (P2 amplitude) to pain words. The control group coped with semantic differentiation (N1) at first, followed by pain word discrimination (P2). In addition, AB to pain occurred only in low-load tasks. As the cognitive load multiplied, we did not find AB in the EP group. Therefore, our study adds further evidence for AB to pain, suggesting the implementation of cognitive load in future AB therapy.

Cortical Representations of Transversus Abdominis and Multifidus Muscles Were Discrete in Patients with Chronic Low Back Pain: Evidence Elicited by TMS.

Introduction: The transversus abdominis (TVA) and multifidus (MF) muscles are the main segmental spinal stabilizers that are controlled by the primary motor cortex of the brain. However, relocations of the muscle representation in the motor cortex may occur after chronic lower back pain (cLBP); it still needs more evidence to be proven. The current study was aimed at applying transcranial magnetic stimulation (TMS) to investigate the changes of representation of TVA and MF muscles at the cortical network in individuals with cLBP. Methods: Twenty-four patients with cLBP and 12 age-matched healthy individuals were recruited. Responses of TVA and MF to TMS during muscle contraction were monitored and mapped over the contralateral cortex using a standardized grid cap. Maps of the center of gravity (CoG), area, volume, and latency were analyzed, and the asymmetry index was also computed and compared. Results: The locations of MF CoG in cLBP individuals were posterior and lateral to the CoG locations in healthy individuals. In the healthy group, the locations of TVA and MF CoG were closed to each other in both the left and right hemispheres. In the cLBP group, these two locations were next to each other in the right hemisphere but discrete in the left hemisphere. In the cLBP group, the cortical motor map of TVA and MF were mutually symmetric in five out of eleven (45.5%) subjects and leftward asymmetric in four out of ten (40.0%) subjects. Conclusions: Neural representations of TVA and MF muscles were closely organized in both the right and left motor cortices in the healthy group but were discretely organized in the left motor cortex in the cLBP group. This provides strong support for the neural basis of pathokinesiology and clinical treatment of cLBP.

Trunk muscle activity during pressure feedback monitoring among individuals with and without chronic low Back pain.

BACKGROUND: Pressure biofeedback unit (PBU) is a widely used non-invasive device to assist core muscle training by providing pressure feedback. The aim this study was to compare the muscle activities of transverse abdominis (TA) and multifidus (MF) at different target pressures (50, 60 and 70 mmHg) of PBU between individuals with and without cLBP. METHODS: Twenty-two patients with chronic LBP (cLBP) and 24 age matched healthy individuals were recruited. Electromyography (EMG) signals were recorded from the TA and MF muscles while the TA and MF were contracted to achieve PBU pressure value of 50, 60 and 70 mmHg in random order. The average EMG amplitude (AEMG) of 3 replicate trials was used in the analysis after normalization to %MVIC. %MVIC is defined as the mean of the three AEMG divided by the AEMG of MVIC. Two-way ANOVA was performed to assess the effects of groups (healthy and cLBP) and the three different target pressures of PBU. Independent sample t-test was conducted to compare between the two groups. Spearman's correlation analysis was performed in the cLBP group to determine potential correlations between EMG activity, NPRS and ODI. RESULTS: The %MVIC of the TA and MF in the cLBP group were higher than the control group at each pressure value (P<0.05). During maximal voluntary isometric contraction (MVIC) of TA and MF, compared with healthy groups, cLBP subjects showed a decrease (TA mean = 47.61 µV; MF mean = 42.40 µV) in EMG amplitudes (P ≤ 0.001). The MVIC of MF was negatively correlated with Numerical Pain Rating Scale (r = - 0.48, P = 0.024) and Oswestry Disability Index (r = - 0.59, P = 0.004). CONCLUSIONS: We measured the trunk muscles activities at different PBU pressure values, which allows the individual to estimate trunk muscle contraction via PBU. Clinicians may be able to confer the data obtained through EMG recordings to adjust the exercise intensity of PBU training accordingly.

Postural effect on gait characteristics by using rolling walkers.

This study was to examine the effect of leaning-forward posture (LFP) on gait parameters while using a rolling walker (RW). A cross-sectional study was conducted in which 23 older female adults were asked to walk with a RW on the GaitRite walkway in two posture situations: upright posture, and LFP caused by pushing the RW forward and then following the RW. The temporal and spatial gait parameters were obtained for data analysis. Results showed that compared with the upright posture, participants with LFP demonstrated significantly increased cadence, decreased velocity and gait cycle time (both swing and stance time decreased). Of spatial parameters, both step and stride length significantly decreased, but the base of support increased significantly. These indicate that LFP during ambulation with a RW could lead participants to a shuffling-like (many steps on short distance) gait pattern. They may help clinicians find proper rehabilitation interventions and appropriate patient education for this specific postural presentation.

Effect of Intermittent Hypoxia Training for Dizziness: A Randomized Controlled Trial.

OBJECTIVE: To study the effect of intermittent hypoxia training (IHT) for dizziness. DESIGN: A single-blind, randomized controlled trial. All participants were recruited from a rehabilitation department in an acute university-affiliated hospital. INTERVENTION: Participants with dizziness were randomly assigned to 2 groups (IHT group and control group). The Dizziness Handicap Inventory, Activities-specific Balance Confidence Scale, and Vertigo Visual Analog Scale were conducted at baseline, end of the fourth week. RESULTS: Among 52 subjects, there were18 males and 34 females, ages 35 to 62 years old (mean [SD] = 46.9 [7.93]). Time length since onset ranged from 12 to 34 months (20.2 [7.15] mo). Dizziness Handicap Inventory, Activities-specific Balance Confidence Scale, Vertigo Visual Analog Scale scores, and attack frequencies of dizziness were improved after IHT intervention in the end of the fourth week. There were significant differences between the IHT group and the control group in the Dizziness Handicap Inventory, Activities-specific Balance Confidence Scale, Vertigo Visual Analog Scale scores, and attack frequencies of dizziness at the end of the fourth week (P < .05). No adverse events occurred during the study. CONCLUSION: IHT could improve dizziness after intervention at the end of the fourth week. IHT could be the effective method for treating dizziness.

Effects of intermittent pressure imitating rolling manipulation on calcium ion homeostasis in human skeletal muscle cells.

BACKGROUND: Homeostasis imbalance of intracellular Ca(2+) is one of the key pathophysiological factors in skeletal muscle injuries. Such imbalance can cause significant change in the metabolism of Ca(2+)-related biomarkers in skeletal muscle, such as superoxide dismutase (SOD), malondialdehyde (MDA) and creatine kinase (CK). Measurements of these biomarkers can be used to evaluate the degree of damage to human skeletal muscle cells (HSKMCs) injury. Rolling manipulation is the most popular myofascial release technique in Traditional Chinese Medicine. The mechanism of how this technique works in ameliorating muscle injury is unknown. This study aimed to investigate the possible Ca(2+) mediated effects of intermittent pressure imitating rolling manipulation (IPIRM) of Traditional Chinese Medicine in the injured HSKMCs. METHODS: The normal HSKMCs was used as control normal group (CNG), while the injured HSKMCs were further divided into five different groups: control injured group (CIG), Rolling manipulation group (RMG), Rolling manipulation-Verapamil group (RMVG), static pressure group (SPG) and static pressure-Verapamil group (SPVG). RMG and RMVG cells were cyclically exposed to 9.5-12.5 N/cm(2) of IPIRM at a frequency of 1.0 Hz for 10 min. SPG and SPVG were loaded to a continuous pressure of 12.5 N/cm(2) for 10 min. Verapamil, a calcium antagonist, was added into the culture mediums of both RMVG and SPVG groups to block the influx of calcium ion. RESULT: Compared with the CNG (normal cells), SOD activity was remarkably decreased while both MDA content and CK activity were significantly increased in the CIG (injured cells). When the injured cells were treated with the intermittent rolling manipulation pressure (RMG), the SOD activity was significantly increased and MDA content and CK activity were remarkably decreased. These effects were suppressed by adding the calcium antagonist Verapamil into the culture medium in RMVG. On the other hand, exposure to static pressure in SPG and SPVG affected neither the SOD activity nor the MDA content and CK activity in the injured muscle cells regardless of the presence of verapamil or not in the culture medium. CONCLUSION: These data suggest that the intermittent rolling pressure with the manipulation could ameliorate HSKMCs injury through a Ca(2+) dependent pathway. Static pressure did not lead to the same results.

Deep Diaphragmatic Breathing-Anatomical and Biomechanical Consideration.

Background: Deep diaphragmatic breathing (DDB) involves slow and fully contraction of the diaphragm with expansion of the belly during inhalation, and slow and fully contraction of the abdominal muscles with reduction of the belly during exhalation. It is the key component of the holistic mind-body exercises commonly used for patients with multimorbidity. Purpose: The purpose of this study was to re-visit and address the fundamental anatomical and biomechanical consideration of the DDB with the relevant literature. Method: Peer-reviewed publications from last the 15 years were retrieved, reviewed, and analyzed. Findings: In this article, we described the updated morphological and anatomical characteristics of the diaphragm. Then, we elucidated in a biomechanical approach how and why the DDB can work on the gastrointestinal, cardiopulmonary, and nervous systems as well as on regulating the intra-abdominopelvic pressure and mind-body interaction to coordinate the diaphragm-pelvic floor-abdominal complex for a variety of physical and physiological activities. Conclusion: Understanding of this updated DDB knowledge may help holistic healthcare professionals including holistic nurses provide better patient education and care management during the DDB or DDB-based mind-body intervention time.

Efficacy of Repetitive Transcranial Magnetic Stimulation over the Supplementary Motor Area on Motor Function in Parkinson's Disease: A Meta-Analysis.

OBJECTIVES: The objective of this study was to assess the effect of repetitive transcranial magnetic stimulation (rTMS) on the supplementary motor area (SMA) in motor function in Parkinson's disease (PD) patients. METHOD: Databases searched included 5 databases from October 7,2022 to January 4, 2023. The Cochrane Bias Risk Assessment Tool was used for quality assessment. Standardized mean differences (SMDs) were calculated using a random-effects model. Outcome measure is the motor function examination of the motor part of Unified Parkinson's Disease Rating Scale (UPDRS-III). RESULTS: Seven studies totaling 374 patients were included. Meta-analysis showed that stimulation of SMA significantly improved motor function in PD patients compared with sham stimulation (SMD = -1.24; 95% CI, -2.24 to -0.24; P = 0.02; I 2 = 93%). Stimulation of the same target (SMA), subgroup analysis showed that high-frequency rTMS (HF-rTMS) is more effective than low-frequency rTMS (LF-rTMS) in improving motor function in PD (SMD = -1.39; 95% CI, -2.21 to -0.57; P = 0.04; I 2 = 77.2%). CONCLUSIONS: Overall, rTMS over SMA had a statistically significant improvement in motor function in PD patients, and HF-rTMS is statistically significantly more effective than LF-rTMS.

Can cerebellar theta-burst stimulation improve balance function and gait in stroke patients? A randomized controlled trial.

BACKGROUND: The cerebellum is a key structure involved in balance and motor control, and has become a new stimulation target in brain regulation technology. Interference theta-burst simulation (iTBS) is a novel simulation mode of repetitive transcranial magnetic simulation. However, the impact of cerebellar iTBS on balance function and gait in stroke patients is still unknown. AIM: The aim of this study was to determine whether cerebellar iTBS can improve function, particularly balance and gait, in patients with post-stroke hemiplegia. DESIGN: This study is a randomized, double-blind, sham controlled clinical trial. SETTING: The study was carried out at the Department of Rehabilitation Medicine in a general hospital. POPULATION: Patients with stroke with first unilateral lesions were enrolled in the study. METHODS: Thirty-six patients were randomly assigned to the cerebellar iTBS group or sham stimulation group. The cerebellar iTBS or pseudo stimulation site is the ipsilateral cerebellum on the paralyzed side, which is completed just before daily physical therapy. The study was conducted five times a week for two consecutive weeks. All patients were assessed before the intervention (T0) and at the end of 2 weeks of treatment (T1), respectively. The primary outcome was the Berg Balance Scale (BBS), while secondary outcome measures included the Fugl Meyer Lower Limb Assessment Scale (FMA-LE), timed up and go (TUG), Barthel Index (BI), and gait analysis. RESULTS: After 2 weeks of intervention, the BBS, FMA-LE, TUG, and BI score in both the iTBS group and the sham group were significantly improved compared to the baseline (all P<0.05). Also, there was a significant gait parameter improvement including the cadence, stride length, velocity, step length compared to the baseline (P<0.05) in the iTBS group, but only significant improvement in cadence was identified in the sham group (P<0.05). Intergroup comparison showed that the BBS (P<0.001), FMA-LE (P<0.001), and BI (P=0.002) in the iTBS group were significantly higher than those in the sham group, and the TUG in the iTBS was significantly lower than that in the sham group (P=0.002). In addition, there were significant differences in cadence (P=0.029), strip length (P=0.046), gain velocity (P=0.002), and step length of affected lower limb (P=0.024) between the iTBS group and the sham iTBS group. CONCLUSIONS: Physical therapy is able to improve the functional recovery in hemiplegic patients after stroke, but the cerebellar iTBS can facilitate and accelerate the recovery, particularly the balance function and gait. Cerebellar iTBS could be an efficient and facilitative treatment for patients with stroke. CLINICAL REHABILITATION IMPACT: Cerebellar iTBS provides a convenient and efficient treatment modality for functional recovery of patients with stroke, especially balance function and gait.

Efficacy of Tai Chi on lower limb function of Parkinson's disease patients: A systematic review and meta-analysis.

Background: At present, the effect of Tai Chi (TC) on lower limb function in patients with Parkinson's disease (PD) is controversial. Therefore, we conducted a meta-analysis on the influence of TC on lower limb function in PD patients. Methods: According to the PRISMA guidelines, seven databases were searched. Randomized controlled trials (RCTS) were selected and screened according to inclusion and exclusion criteria. We assessed the quality of the studies using the Cochrane Risk of Bias tool and then extracted the characteristics of the included studies. The random effect model was adopted, and heterogeneity was measured by I 2 statistic. Results: A total of 441 articles were screened, and 10 high-quality RCTs were with a total of 532 patients with PD met Our inclusion criteria. Meta-analysis showed that compared To control groups TC improved several outcomes. TC significantly improved motor function (SMD = -0.70; 95% CI = -0.95, -0.45; p < 0.001; I 2 = 35%), although The results were not statistically significant for The subgroup analysis of TC duration (SMD = -0.70; 95% CI = -0.95, -0.45; p = 0.88; I 2 = 0%;). TC significantly improved balance function (SMD = 0.89; 95% CI = 0.51, 1.27; p < 0.001; I 2 = 54%), functional walking capacity (SMD = -1.24; 95% CI = -2.40, -0.09; p = 0.04; I 2 = 95%), and gait velocity (SMD = 0.48; 95% CI = -0.02, 0.94; p = 0.04; I 2 = 78%), But Did Not improve endurance (SMD = 0.31; 95% CI = -0.12, 0.75; p = 0.16; I 2 = 0%), step length (SMD = 0.01; 95% CI = -0.34, 0.37; p = 0.94; I 2 = 29%), and cadence (SMD = 0.06; 95% CI = -0.25, 0.36; p = 0.70; I 2 = 0%). Conclusion: TC has beneficial effects on motor function, balance function, functional walking ability, and gait velocity, but does not improve walking endurance, stride length, and cadence.

The mechanism of chemokine receptor ACKR2 in cognitive impairment in young rats with traumatic brain injury.

OBJECTIVE: To investigate the role of chemokine receptor ACKR2 in cognitive impairment in young rats with traumatic brain injury. METHODS: Seventy-five young rats were randomly divided into TBI group, TBI+Negative control (NC) group, TBI+Sensory integration (SI) group, TBI+Atypical chemokine receptor 2 (ACKR2) group and TBI+SI+ACKR2 group. We employed several techniques, including the water maze test, transmission electron microscope, HE staining, enzyme-linked immunosorbent assay, RT-PCR, western blotting to elucidate the role of ACKR2 in young rats with traumatic brain injury. RESULTS: We observed that the ability of learning and memory were significantly decreased, the serum inflammatory factors CCL2, IL-1ß and TNF-α were increased, the expression of Tau and NG2 was increased, and the expression of ACKR2 was decreased in TBI rats. After ACKR2 overexpression combined with SI, the learning ability and memory ability of TBI rats were improved, the levels of CCL2, IL-1ß, TNF-α were decreased, the expressions of Tau and NG2 were decreased, which were better than those of SI and ACKR2 groups. CONCLUSION: ACKR2 may be an effective method for improving the results after TBI in young rats.

Manual Therapy Treatment for Penile Pain- A Clinical Case Report with 6-Month Follow-up.

BACKGROUND: Male genital pain, which is neither related to genitourinary nor other obvious pathology, is an uncommon symptom in male patients and not frequently treated using manual therapy. The purpose of this case study is to describe a clinical reasoning process in combination with anatomy-based differential diagnosis and manual treatment for genital pain. CASE DESCRIPTION: A male patient with a 3-week acute onset of genital pain was hospitalized and referred for evaluation and treatment after unsuccessful treatment with medication and acupuncture. Clinical examination was performed indicating a possible nerve entrapment followed by interventions of ligamentous articular strain, high-velocity low-amplitude (HVLA) manipulation, and strain- and counterstain, coupled with soft tissue stretching to lumbar and inguinal areas to address a possible lumbar referral potentially from L1 and/or ilioinguinal nerve entrapment. OUTCOMES: After 4 consecutive days of manipulative treatment, pain decreased from 9/10 to 0/10 and the Barthel Index improved from 50 to 95. A 6-month follow-up revealed complete resolution of symptoms with no recurrence. DISCUSSION: This case illustrates that a detailed history and examination along with a reasoned diagnostic process to determine an appropriate intervention strategy may improve patient care using manual therapy techniques. CONCLUSION: By utilizing a deductive reasoning process related to the penile area, clinicians may better apply manual therapy techniques for successful treatment.

Effects of a short eight Tai Chi-forms for the pre-frail elderly people in senior living communities.

PURPOSE: To investigate effects of a short 8-form Tai Chi exercise on physical function, fear of falling, and depression in pre-frail elderly people living in senior communities. METHODS: This 8-week randomized controlled trial was conducted in senior living communities with qualified pre-frail elderly subjects in a Tai Chi group (TCG, n= 32) and a control group (CG, n = 33). The TCG received TC intervention: three times/week, 60 min each; while the CG did usual care only. Assessments of the 30-s chair rise test (CRT), 4.5-m walking speed (WS), fear of falling (FOF), and Geriatric Depression Scale (GDS), were all applied at baseline, end of 4th week, and end of 8th week. RESULTS: Between-group comparison at the 4th week showed significantly better outcomes in CRT (TCG: 14.56 ± 1.87; CG: 11.48 ± 2.83; P< .001) and WS (TCG: 4.28 ± 0.69; CG: 5.11 ± 1.16; P = .001) in the TCG than those in the CG, but not in FOF (TCG: 0.56 ± 0.56; CG: 0.79 ± 0.89; P = .228) and GDS (TCG: 7.91 ± 5.54; CG: 9.58 ± 6.85; P = .285). However, at the 8th week, significant differences (P< .001) were found in all four assessments: (1) CRT: TCG vs CG: 17.28 ± 2.00 vs 11.36± 2.94; (2) WS: TCG vs CG: 3.94 ± 0.59 vs 5.17 ± 1.22; (3) FOF: TCG vs CG: 0.16 ± 0.37 vs 1.00 ± 0.90; and (4) GDS: TCG vs CG: 3.84 ± 3.60 vs 9.97 ± 6.80, and the intervention effect of 8 weeks was better than at 4 weeks. For within-group comparison of the TCG, significant improvements were identified in CRT (P< .001), WS (P = .008), and FOF (P = .002); but not in GDS, P = .121 at the 4th week, and also in CRT (P< .001), WS (P< .001), FOF (P< .001), and GDS (P< .001) at the 8th week. On the other hand, there were no significant differences in the CG for pre- and post-comparison (CRT: P = .891; WS: P = .984; FOF: P = .636; GDS: P = .822). CONCLUSION: This short-form TC exercise could improve physical function (the lower limbs' strength and gait speed), fear of falling, and depression.

Sling Exercise Can Drive Cortical Representation of the Transversus Abdominis and Multifidus Muscles in Patients With Chronic Low Back Pain.

Objective: The transversus abdominis (TrA) and multifidus (MF) muscles are essential in preventing chronic low back pain (CLBP) recurrence by maintaining segmental stabilization and stiffness. Sling exercise is a high-level core stability training to effectively improve the activities of the TrA and MF muscles. However, the neural mechanism for sling exercise-induced neural plasticity change in the primary motor cortex (M1) remains unclear. This study aimed to investigate the role of sling exercise in the reorganization of the motor cortical representation of the TrA and MF muscles. Methods: Twenty patients with CLBP and 10 healthy individuals were recruited. For map volume, area, the center of gravity (CoG) location (medial-lateral location and anterior-posterior location), and latency, two-way ANOVA was performed to compare the effects of groups (the CLBP-pre, CLBP-post, and healthy groups) and the two muscles (the TrA and MF muscles). The Visual Analog Scale (VAS), the Oswestry Disability Index (ODI), and postural balance stability were assessed at baseline and at the end of 2 weeks of sling exercise. Linear correlations between VAS or ODI and CoG locations were assessed by Pearson's correlation test. Results: 2 weeks of sling exercise induced both the anterior-medial (P < 0.001) and anterior-posterior (P = 0.025) shifts of the MF muscle representation at the left motor cortex in patients with CLBP. Anterior-medial (P = 0.009) shift of the TrA muscle representation at the right motor cortex was observed in patients with CLBP. The motor cortical representation of the two muscles in patients with CLBP after sling exercise (TrA: 2.88 ± 0.27 cm lateral and 1.53 ± 0.47 cm anterior of vertex; MF: 3.02 ± 0.48 cm lateral and 1.62 ± 0.40 cm anterior of vertex) closely resembled that observed in healthy individuals (TrA: 2.83 ± 0.48 cm lateral and 2.00 ± 0.43 cm anterior of vertex; MF: 2.94 ± 0.43 cm lateral and 1.77 ± 0.48 cm anterior of vertex). The VAS and the ODI were reduced following the sling exercise (VAS: P < 0.001; ODI: P < 0.001). Conclusion: This study provides evidence that sling training can drive plasticity changes in the motor system, which corresponds with the reduction in pain and disability levels in patients with CLBP. This study was registered in the Chinese Clinical Trial Registry (Clinical Trial Registration Number: ChiCTR2100045904, http://www.chictr.org.cn/showproj.aspx?proj=125819). Clinical Trial Registration: ChiCTR2100045904.

Effect of acupuncture combined with rehabilitation on cognitive and motor functions in poststroke patients.

The aim of the study was to explore the effect of acupuncture combined with rehabilitation on cognitive and motor functions in poststroke patients. All patients were divided into Group A and Group B based on different interventions (Group A: acupuncture + conventional rehabilitation, Group B: conventional rehabilitation alone). Acupuncture was conducted once a day, five times a week for 8 weeks, and rehabilitation (including physical therapy and occupational therapy) was conducted for 2 hr per session, once a day, five times a week for 8 weeks. Mini-mental State Examination (MMSE) and Fugl-Meyer Assessment (FMA) were used to assess the motor and cognitive functions at baseline and the end of 8 weeks. After the intervention, FMA and MMSE scores were improved significantly in the two groups (p <.05), compared with the scores prior to intervention. After 8 weeks of intervention, a statistically significant difference in the FMA and MMSE scores was observed between the Group A and the Group B. The results suggested that the combined intervention is more effective than the conventional rehabilitation alone in improving cognitive and motor functions in poststroke patients.

Treatment effect and mechanism of Fu's subcutaneous needling among patients with shoulder pain: A retrospective pilot study.

Fu's subcutaneous needling (FSN) is a new acupuncture therapy developed from acupuncture and Traditional Chinese Medicine models. The aim of this study was to investigate the effect of FSN on shoulder pain. In this retrospective comparative study, patient case files with shoulder pain (Group A) treated with FSN were analyzed and compared with the same number of patients with shoulder pain (Group B) treated with conventional acupuncture and physical therapy. Motion-related pain (MRP), pain under pressure (PUP), and Range of motion (ROM) were collected before and after intervention. In the 68 patients, there were 39 males and 29 females, aged 21-53 years old (mean ± SD = 36.4 ± 8.15) with onset time ranging from 1 day to 7 days (mean ± SD = 3.15 ± 1.73). MRP, PUP, and ROM scores were improved after FSN intervention (p < .05). There were significant differences between group A and group B in MRP, PUP, and ROM scores after FSN intervention and 1 week follow-up (p < .05). No adverse events, such as fainting and sharp pain, occurred during the treatment process. FSN can be an effective rehabilitation intervention for improving shoulder pain and shoulder range of motion.

Effect of Sitting Ba-Duan-Jin Exercises on Balance and Quality of Life Among Older Adults: A Preliminary Study.

PURPOSE: The aim of this study was to ascertain whether ba-duan-jin (BDJ) can improve balance and enhance the quality of life among older adults. DESIGN: This pilot study was designed as a single group pre-post comparison test. METHODS: Sixteen older adults were qualified and recruited for this study at local retirement communities. Assessments for pre- and postintervention among the subjects included Single-Leg Stance, Chair Rising Test, Tinetti Balance Test, Modified Falls Efficacy Scale, and 12-Item Short Form Health Survey Questionnaire for quality of life. FINDINGS: After 12 weeks of BDJ training, significant improvements were identified in Single-Leg Stance, Tinetti Balance Test, Modified Falls Efficacy Scale, and 12-Item Short Form Health Survey (all p < .01); however not for the Chair Rising Test (p > .05). CONCLUSION: The results indicate that BDJ can improve balance, lower extremity strength, quality of life, and decrease fear of falling among older adults. CLINICAL RELEVANCE: BDJ is an effective rehabilitation training method and can improve balance and motor function among older people. Rehabilitation nursing plays a key role in functional rehabilitation of older people.
