Usability of a telehealth-nurse supported home-based walking training for peripheral arterial disease - The Keep Pace! pilot study.

Background: Guidelines recommend walking trainings for peripheral arterial disease (PAD) management. Supervised walking training is superior to walking advise to improve the walking distance. Telehealth service with nurse support may close this gap. Patients and methods: This study introduces a telehealth service, "Keep pace!", which has been developed for patients with symptomatic PAD (Fontaine stage IIa and IIb), enabling a structured home-based walking training while monitoring progress via an app collecting unblinded account of steps and walking distance in self-paced 6-minute-walking-tests by geolocation tracking to enhance intrinsic motivation. Supervision by nurses via telephone calls was provided for 8 weeks, followed by 4 weeks of independent walking training. Patient satisfaction, walking distance and health-related quality of life were assessed. Results: 19 patients completed the study. The analysis revealed an overall high satisfaction with the telehealth service (95.4%), including system quality (95.1%), information quality (94.4%), service quality (95.6%), intention to use (92.8%), general satisfaction with the program (98.4%) and health benefits (95.8%). 78.9% asserted that the telehealth service lacking nurse calls would be less efficacious. Pain-free walking distance (76.3±36.8m to 188.4±81.2m, +112.2%, p<0.001) as well as total distance in 6-minute-walking test (308.8±82.6m to 425.9±107.1m, +117.2%, p<0.001) improved significantly. The telehealth service significantly reduced discomfort by better pain control (+15.5%, p=0.015) and social participation (+10.5%, p=0.042). Conclusions: In conclusion, patients were highly satisfied with the telehealth service. The physical well-being of the PAD patients improved significantly post vs. prior the telehealth program.

Effects of robot-assisted walking training on balance, motor function, and ADL depending on severity levels in stroke patients.

BACKGROUND: Despite the explosive increase in interest regarding Robot-Assisted Walking Training (RAWT) for stroke patients, very few studies have divided groups according to the severity levels of patients and conducted studies on the effects of RAWT. OBJECTIVE: The purpose of this study was to present a definite basis for physical therapy using the robot-assisted walking device through a more detailed comparison and analysis and to select the optimal target of RAWT. METHODS: This study was designed as a prospective and randomized controlled trial to investigate the effect of RAWT on balance, motor function, and Activities of Daily Living (ADL) depending on severity levels in stroke patients. 100 participants were randomly divided into study and control groups in equal numbers. The study group was 49 and the control group was 47. One from the study group and three from the control group were eliminated. The study period is four weeks in total, and RAWT is performed five times a week for 40 minutes only for study group. During the same period, all group members had 30 minutes of Conventional Physiotherapy (CP) five times a week. RESULTS: The results of this study clearly confirmed that RAWT combined with CP produces more significant improvement in patients with stroke than the CP alone. And they indicated that RAWT had a more considerable effect in the poor or fair trunk control group for trunk balance and in the high fall risk group for balance. In motor function, RAWT showed its value in the severe and marked motor impairment group. The total or severe dependence group in ADL experienced more improvements for RAWT. CONCLUSION: This study can be concluded that the lower the level of physical functions, the more effective it responds to RAWT. As demonstrated in the results of this study, the potential of current robotic technology appears to be greatest at very low functional levels of stroke patients. Patients with low functional levels among stroke patients may benefit from robot rehabilitation.

A 12-Week Ballroom Dance Training Improves Physical Fitness Performance More Than Walking Training in Older Women, Regardless of Vitamin B12 or D Adequacy.

AIM: This study aimed to compare the effects of Ballroom Dancing (BD) versus Walking Training (WT) on the physical fitness performance in physically independent older women with adequate or inadequate levels of vitamins B12 and D. METHODS: Forty-three sedentary women aged 68.5 ± 6.5 years, were allocated to the BD (n = 23) or WT (n = 20) groups. They took part in a 12-week intervention, performed 3 times a week, for about 50 minutes with moderate effort intensity. Data were collected through Short Physical Performance Battery (SPPB), 6 minutes Walk Test (6MWT), Hand Grip Test (HGT), Isokinetic tests for lower limbs and blood tests to detect serum levels of vitamins B12 and D. RESULTS: The BD group performed better after the intervention in relation to the WT in the Sit and Stand Test (SST) (BD pre = 3.1 score vs post = 3.8 score; WT pre = 2.8 score vs post = 3.4 score; P = .02) and in the Peak Torque 180° extension (PKTOQ 180° extension) (BD pre = 56.7 Nm vs post = 61.2 Nm, WT pre = 56.7 Nm vs post = 56.1; P < .01). CONCLUSION: A time effect was observed in all other variables, with the exception of HGT. Both interventions improved physical fitness performance, regardless of the adequacy of vitamins B12 and D, but the older women from BD obtained significant improvements in more variables than the WT.

Effects of backward walking training on balance, gait, and functional mobility in people with multiple sclerosis: A randomized controlled study.

BACKGROUND: Backward walking training (BWT) can have a positive effect on balance, gait, and functional mobility in neurological diseases; however, the effectiveness of BWT has not been examined in multiple sclerosis (MS). Therefore, the study aimed to investigate the effects of BWT on balance, gait, and functional mobility in people with MS (PwMS). METHOD: Nineteen PwMS were randomly allocated to either the experimental group (n=10) and the control group (n=9). The experimental group received BWT in addition to conventional walking training (CWT) while the control group only received CWT. Both groups performed training three times a week for 8 weeks. Participants were assessed with the Berg Balance Scale (BBS), four square step test (FSST), activities-specific balance confidence scale (ABC), timed 25-foot walk test (T25FW), dynamic gait index (DGI), 3-meter backward walk test (3MBWT), Multiple Sclerosis Walking Scale-12 (MSWS-12), and timed up and go test (TUG) before and after training. RESULTS: After training, both groups showed significant improvements on the T25FW, and TUG (p<0.05) while only the experimental group showed significant improvements on the BBS, FSST, ABC, DGI, 3MBWT, and MSWS-12 (p<0.05). The experimental group significantly improved more than the control group in all outcomes (p<0.05) except for the T25FW (p=0.202). CONCLUSION: BWT in addition to CWT is an effective way to improve balance, gait, and functional mobility for PwMS. These results suggest that BWT may be a potentially useful treatment approach when added to CWT in the rehabilitation of MS.

Systematic review and network meta-analysis of robot-assisted gait training on lower limb function in patients with cerebral palsy.

OBJECTIVE: This study aimed to evaluate the effectiveness of robot-assisted gait training (RAGT) in treating lower extremity function in patients with cerebral palsy (CP) and compare the efficacy differences between different robotic systems. METHODS: PubMed, Web of Science, Cochrane Library, Embase, CNKI, VIP, CBM, and Wanfang databases were searched to collect randomized controlled trials of RAGT for lower extremity dysfunction in patients with CP from the time the databases were created until December 26, 2022. The D and E of Gross Motor Function Measure-88 (GMFM-88) assessed lower limb motor function. Berg Balance Scale (BBS) was used to assess balance function. Walking endurance and speed were assessed using the 6-minute walk test (6MWT) and walking speed. The modified Ashworth Scale (MAS) was used to assess the degree of muscle spasticity in the lower extremities. The Cochrane Risk Assessment Scale and the Physiotherapy Evidence Database (PEDro) scale were used for qualitative assessment in the studies included. RevMan 5.4 was used for data merging and statistical analysis. R 4.2.0 and ADDIS 1.16.8 were used to map the network relationships and to perform the network meta-analysis. RESULTS: A total of 14 studies were included in the review. The meta-analysis showed that RAGT significantly improved GMFM-88 D and E, BBS, and 6MWT scores in CP patients compared with conventional rehabilitation. However, for walking speed and MAS, the intervention effect of RAGT was insignificant. The network meta-analysis showed that the best probability ranking for the effect of the 3 different robots on the GMFM-88 D score was LokoHelp (P = 0.66) > Lokomat (P = 0.28) > 3DCaLT (P = 0.06) and the best probability ranking for the GMFM-88 E score was LokoHelp (P = 0.63) > 3DCaLT (P = 0.21) > Lokomat (P = 0.16). CONCLUSION: RAGT positively affects walking and balance function in patients with CP, while efficacy in improving gait speed and muscle spasticity is unknown. The best treatment among the different robots is LokoHelp. Future high-quality, long-term follow-up studies are needed to explore the clinical efficacy of RAGT in depth.

Gait quality after robot therapy compared with physiotherapy in the patient with incomplete spinal cord injured: A systematic review.

Background: Spinal cord injury results in the interruption of neuronal conduction in the spinal cord, a condition that occurs in 0.1% of the world's population. This results in severe limitations in autonomy including locomotor function. Its recovery can be pursued through conventional isolated physiotherapeutic rehabilitation (overground walking training - OGT) or associated with Robot-assisted gait training - RAGT (e.g.: Lokomat ®). Aim: The aim of this review is to compare the effectiveness of RAGT combined with conventional physiotherapy. Methods: The databases consulted, from March 2022 to November 2022, were PubMed, PEDro, Cochrane Central Register of Controlled Trials (Cochrane Library) and CINAHL. RCT studies of people with incomplete spinal cord injuries treated with RAGT and/or OGT with the aim of improving walking were analysed. Results: Among the 84 RCTs identified, 4 were included in the synthesis, with a total of 258 participants. The outcomes analysed concerned both locomotor function through lower limb muscle strength and the need for assistance in walking, using the WISCI-II scale and the LEMS. Robotic treatment stimulated the greatest improvements in the four studies; however, they were not always statistically significant. Conclusion: A rehabilitation protocol combining RAGT with conventional physiotherapy is more effective than isolated OGT in improving ambulation in the subacute phase.

A robotic treadmill system to mimic overground walking training with body weight support.

Introduction: Body weight support overground walking training (BWSOWT) is widely used in gait rehabilitation. However, existing systems require large workspace, complex structure, and substantial installation cost for the actuator, which make those systems inappropriate for the clinical environment. For wide clinical use, the proposed system is based on a self-paced treadmill, and uses an optimized body weight support with frame-based two-wire mechanism. Method: The Interactive treadmill was used to mimic overground walking. We opted the conventional DC motors to partially unload the body weight and modified pelvic type harness to allow natural pelvic motion. The performance of the proposed system on the measurement of anterior/posterior position, force control, and pelvic motion was evaluated with 8 healthy subjects during walking training. Results: We verified that the proposed system was the cost/space-effective and showed the more accurate anterior/posterior position than motion sensor, comparable force control performance, and natural pelvic motion. Discussion: The proposed system is cost/space effective, and able to mimic overground walking training with body weight support. In future work, we will improve the force control performance and optimize the training protocol for wide clinical use.

Effect of Nordic Walking Training on Physical Fitness and Self-Assessment of Health of People with Chronic Non-Specific Lower Back Pain.

In order to determine the impact of a four-week cycle of Nordic Walking (NW) training on the physical fitness of people with chronic non-specific lower back pain and the impact of this form of activity on their self-assessment of health quality, the study included 80 men and women aged 29 to 63 years. The subjects were divided into two equal (40-person) groups: experimental and control. In both study groups the degree of disability in daily activities caused by back pain was assessed with the FFb-H-R questionnaire, the physical fitness was evaluated with the modified Fullerton test and the sense of health quality was assessed with the SF-36 questionnaire. The same tests were repeated after four weeks. In the experimental group NW training was applied between the two studies. During four weeks, 10 training units were carried out, and each training session lasted 60 min with a two-day break between each training. The four-week NW training resulted in a statistically significant sense of disability due to back pain (p < 0.001), significant improvement of physical fitness expressed by improvement in upper (p < 0.001) and lower (p < 0.01) body strength, upper and lower body flexibility (p < 0.001) and ability to walk a longer distance in a 6-min walk test (p < 0.001). The training participants also showed significant improvements in health quality in both physical (p < 0.001) and mental (p < 0.001) components. The four-week NW training has a positive impact on the physical fitness of men and women with chronic lower back pain. Participation in NW training also contributes to a significant reduction in the sense of disability caused by back pain and improvement in the self-assessment of health quality.

Evidence for the Efficacy of Commercially Available Wearable Biofeedback Gait Devices: Consumer-Centered Review.

BACKGROUND: The number of wearable technological devices or sensors that are commercially available for gait training is increasing. These devices can fill a gap by extending therapy outside the clinical setting. This was shown to be important during the COVID-19 pandemic when people could not access one-on-one treatment. These devices vary widely in terms of mechanisms of therapeutic effect, as well as targeted gait parameters, availability, and strength of the evidence supporting the claims. OBJECTIVE: This study aimed to create an inventory of devices targeting improvement in gait pattern and walking behavior and identify the strength of the evidence underlying the claims of effectiveness for devices that are commercially available to the public. METHODS: As there is no systematic or reproducible way to identify gait training technologies available to the public, we used a pragmatic, iterative approach using both the gray and published literature. Four approaches were used: simple words, including some suggested by laypersons; devices endorsed by condition-specific organizations or charities; impairment-specific search terms; and systematic reviews. A findable list of technological devices targeting walking was extracted separately by 3 authors. For each device identified, the evidence for efficacy was extracted from material displayed on the websites, and full-text articles were obtained from the scientific databases PubMed, Ovid MEDLINE, Scopus, or Google Scholar. Additional information on the target population, mechanism of feedback, evidence for efficacy or effectiveness, and commercial availability was obtained from the published material or websites. A level of evidence was assigned to each study involving the device using the Oxford Centre for Evidence-Based Medicine classification. We also proposed reporting guidelines for the clinical appraisal of devices targeting movement and mobility. RESULTS: The search strategy for this consumer-centered review yielded 17 biofeedback devices that claim to target gait quality improvement through various sensory feedback mechanisms. Of these 17 devices, 11 (65%) are commercially available, and 6 (35%) are at various stages of research and development. Of the 11 commercially available devices, 4 (36%) had findable evidence for efficacy potential supporting the claims. Most of these devices were targeted to people living with Parkinson disease. The reporting of key information about the devices was inconsistent; in addition, there was no summary of research findings in layperson's language. CONCLUSIONS: The amount of information that is currently available to the general public to help them make an informed choice is insufficient, and, at times, the information presented is misleading. The evidence supporting the effectiveness does not cover all aspects of technology uptake. Commercially available technologies help to provide continuity of therapy outside the clinical setting, but there is a need to demonstrate effectiveness to support claims made by the technologies.

Changes in miRNA expression in patients with peripheral arterial vascular disease during moderate- and vigorous-intensity physical activity.

BACKGROUND: Walking is the preferred therapy for peripheral arterial disease in early stage. An effect of walking exercise is the increase of blood flow and fluid shear stress, leading, triggered by arteriogenesis, to the formation of collateral blood vessels. Circulating micro-RNA may act as an important information transmitter in this process. We investigated the acute effects of a single bout of 1) aerobic walking with moderate intensity; and 2) anaerobic walking with vigorous intensity on miRNA parameters related to vascular collateral formation. METHODS: Ten (10) patients with peripheral arterial disease with claudication (age 72 ± 7 years) participated in this two-armed, randomized-balanced cross-over study. The intervention arms were single bouts of supervised walking training at (1) vigorous intensity on a treadmill up to volitional exhaustion and (2) moderate intensity with individual selected speed for a duration of 20 min. One week of washout was maintained between the arms. During each intervention, heart rate was continuously monitored. Acute effects on circulating miRNAs and lactate concentration were determined using pre- and post-intervention measurement comparisons. RESULTS: Vigorous-intensity walking resulted in a higher heart rate (125 ± 21 bpm) than the moderate-intensity intervention (88 ± 9 bpm) (p < 0.05). Lactate concentration was increased after vigorous-intensity walking (p = 0.005; 3.3 ± 1.2 mmol/l), but not after moderate exercising (p > 0.05; 1.7 ± 0.6 mmol/l). The circulating levels of miR-142-5p and miR-424-5p were up-regulated after moderate-intensity (p < 0.05), but not after vigorous-intensity training (p > 0.05). CONCLUSION: Moderate-intensity walking seems to be more feasible than vigorous exercises to induce changes of blood flow and endurance training-related miRNAs in patients with peripheral arterial disease. Our data thus indicates that effect mechanisms might follow an optimal rather than a maximal dose response relation. Steady state walking without the necessity to reach exhaustion seems to be better suited as stimulus.

Clinical Effects of MOTOmed Intelligent Exercise Training Combined with Intensive Walking Training on the Rehabilitation of Walking, Nerve and Lower Limb Functions among Patients with Hemiplegia after Stroke.

Objectives: To investigate the clinical effects of MOTOmed intelligent exercise training combined with intensive walking training on the rehabilitation of walking, nerve and lower limb functions among patients with hemiplegia after stroke. Methods: Randomized controlled trial was used in this study. Fifty-two patients with hemiplegia after stroke treated in 82nd Army Group Military Hospital from February 2017 to February 2018 were selected as the subjects and randomly divided into the control group and the observation group, each with 26 cases. The control group underwent intensive walking training, and the observation group underwent MOTOmed intelligent exercise training on the control group basis. Both groups' rehabilitation of walking function, nerve function and lower limb function were observed. Results: Both groups had significantly increased FAC score and 10-m maximum walking speed (P < 0.05), and the observation group had significantly higher results than those of the control group (P < 0.05); both groups had significantly higher FMA scores than before treatment (P < 0.05), and the observation group had significantly higher scores than those of the control group (P < 0.05); both groups after two months of treatment had significantly increased NGF, NT-3 and BDNF (P<0.05), and the observation group had significantly higher levels than those of the control group (P<0.05). Conclusion: MOTOmed intelligent exercise training combined with intensive walking training can significantly improve the walking function, nerve function and lower limb function among patients with hemiplegia after stroke.

Effects of Yogurt Intake on Cardiovascular Strain during Outdoor Interval Walking Training by Older People in Midsummer: A Randomized Controlled Study.

We examined whether post-exercise yogurt intake reduced cardiovascular strain during outdoor interval walking training (IWT) in older people during midsummer. The IWT is a training regimen repeating slow and fast walking at ~40% and ≥70% peak aerobic capacity, respectively, for 3 min each per set, ≥5 sets per day, and ≥4 days/wk. We randomly divided 28 male and 75 female older people (~73 yr), who had performed IWT ≥12 months, into a carbohydrate group (CHO-G) consuming jelly (45 g CHO, 180 kcal) and a yogurt group (YGT-G) consuming a yogurt drink (9.3 g protein, 39 g CHO, 192 kcal) immediately after daily IWT for 56 days while monitoring exercise intensity and heart rate (HR) with portable devices. We analyzed the results in 39 subjects for the CHO-G and 37 subjects for the YGT-G who performed IWT ≥ 4 days/wk, ≥60 min total fast walking/wk, and ≥4 sets of each walk/day. We found that the mean HR for fast walking decreased significantly from the baseline after the 30th day in the YGT-G (p < 0.03), but not in the CHO-G (p = 1.00). There were no significant differences in training achievements between the groups. Thus, post-exercise yogurt intake might reduce cardiovascular strain during outdoor walking training in older people.

Backward Walking Training Impacts Positive Effect on Improving Walking Capacity after Stroke: A Meta-Analysis.

Objective: The meta-analysis aimed to investigate the potential effect of backward walking training (BWT) on walking function improvement among stroke patients. Data sources: Eligible studies were systematically searched in PubMed, Embase, Web of Science, and Cochrane Library. Methods: Heterogeneity among enrolled studies was assessed. Weighted mean difference (WMD) with its 95% confidence interval (CI) was used to pool the outcomes. Results: Seven articles were included. BWT significantly improved motor functions of stroke patients including 10-meter walk test (WMD (95% CI) = 0.11 (0.01, 0.21) meters/second; p = 0.03); cadence (WMD (95% CI) = 4.00 (0.99, 7.02) step/minute; p < 0.01); Berg balance scale (WMD (95% CI) = 4.38 (2.60, 6.15); p < 0.01); paretic step length (WMD (95% CI) = 5.32 (1.97, 8.67) cm; p < 0.01); and stride length (WMD (95% CI) = 6.61 (0.70, 12.51) cm; p = 0.03) as compared with control group. Conclusion: Our study revealed that BWT had a positive influence on walking function improvement among patients after stroke.

Effectiveness of walking training on balance, motor functions, activity, participation and quality of life in people with chronic stroke: a systematic review with meta-analysis and meta-regression of recent randomized controlled trials.

PURPOSE: To review and quantify the effects of walking training for the improvement of various aspects of physical function of people with chronic stroke. METHODS: We conducted a systematic search and meta-analysis of randomized controlled trials (RCTs) of chronic stroke rehabilitation interventions published from 2008 to 2020 in English or French. Of the 6476-screened articles collated from four databases, 15 RCTs were included and analyzed. We performed a meta-regression with the total training time as dependent variable in order to have a better understanding of how did the training dosage affect the effect sizes. RESULTS: Treadmill walking training was more effective on balance and motor functions (standardized mean difference (SMD)=0.70[0.02, 1.37], p = 0.04) and 0.56[0.15, 0.96], p = 0.007 respectively). Overground walking training improved significantly walking endurance (SMD = 0.38[0.16, 0.59], p < 0.001), walking speed (MD = 0.12[0.05, 0.18], p < 0.001), participation (SMD = 0.35[0.02, 0.68], p = 0.04) and quality of life (SMD = 0.46[0.12, 0.80], p = 0.008). Aquatic training improved balance (SMD = 2.41[1.20, 3.62], p < 0.001). The Meta-regression analysis did not show significant effect of total training time on the effect sizes. CONCLUSION: Treadmill and overground walking protocols consisting of ≥30 min sessions conducted at least 3 days per week for about 8 weeks are beneficial for improving motor impairments, activity limitations, participation, and quality of life in people with chronic stroke.Implications for rehabilitationTreadmill walking training is effective for improving balance and motor functions.Overground walking training improved significantly walking endurance, walking speed, participation and quality of life.Treadmill and overground walking protocols consisting of ≥30 min sessions conducted at least 3 days per week for about 8 weeks are beneficial for improving motor impairments, activity limitations, participation, and quality of life in patient with chronic stroke.

Effects of walking training on risk markers of cardiovascular disease in individuals with chronic spinal cord injury.

OBJECTIVE: To investigate the effects of an 8-week walking training program on glycemic control, lipid profile, and inflammatory markers in individuals with chronic spinal cord injury (SCI). DESIGN: A pilot, single-group, pretest-posttest study. SETTING: A neuromuscular research laboratory. PARTICIPANTS: Eleven participants with chronic SCI. INTERVENTION: An 8-week walking training program using a treadmill, a body weight-supported system, and an assistive gait training device. OUTCOME MEASURES: Levels of glycated hemoglobin (HbA1c), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP), and interleukin-6 were assessed before and after the walking training. RESULTS: Following the walking training, there was a statistically significant decrease in HbA1c level (P<0.01) of uncertain clinical significance. The lipid profile improved after training, as shown by a statistically and clinically significant increase in HDL-C level (P<0.01) and a statistically significant decrease in LDL-C level (P<0.1) of no clinical significance. The ratio of LDL-C to HDL-C was significantly reduced (P<0.01). In regard to inflammatory markers, concentrations of IL-6 showed a significant reduction after training (P=0.05) of unknown clinical significance, while those of CRP trended to decrease (P=0.13). CONCLUSION: The findings of this pilot study suggest that an 8-week walking training program may produce favorable changes in risk markers of cardiovascular disease in individuals with chronic SCI as shown by clinically meaningful improvements in HDL-C, and small changes in the right direction, but uncertain clinical significance, in HbA1c, LDL-C and IL-6. A randomized controlled trial is needed to compare the effects of walking training on these outcome measures with those of other exercise modalities suitable for this population, and to see if more prolonged exercise exposure leads to favorable parameters of significant size to justify the exercise modality.

Effects of standing and walking training using a laser pointer based on stimulus-driven attention for behavioural outcome in spatial neglect: A single-case study.

The therapy for unilateral spatial neglect (USN) is unclear. This case report investigated the effect of standing and walking training using a laser pointer based on stimulus-driven attention for USN. The patient was a right-handed 79-year-old man with cardiogenic cerebral embolism in the right middle and posterior cerebral arteries. Initially, we evaluated the absence of hemiparalysis in the lower limb and sensory disorder; almost all daily activities were performed independently. Intervention effects were verified using the BABA method. The course of the four phases (B1, A1, B2, A2) was conducted for 5 days. In the B1 and B2 phases, standing and walking training using a laser pointer was performed additionally to conventional physical therapy. Outcomes were measured using the Behavioural Inattention Test conventional subtest (BIT-c), Catherine Bergego Scale (CBS), and modified Posner task (MPT). The BIT-c remained unchanged in each phase. CBS scores improved after B1 and B2. In the MPT, the reaction time in the left space reduced after B1 and B2 compared with those in the A1 and A2 control phases. In this case, training may have contributed to the improvement in the response to the neglected space and behavioural assessment of USN.

Lokomat training can significantly improve the walking ability of stroke survivors with lower limb spasm / 中华物理医学与康复杂志

Objective:To explore the effect of Lokomat training on the walking ability of stroke survivors with lower limb spasm.Methods:Eighty stroke survivors with lower limb spasm were randomly divided into an observation group and a control group, each of 40. Their routine rehabilitation treatment included normal limb positioning, passive joint movement, turnover training and inclined bed standing training. In addition, the control group underwent flat-ground walking training, while the observation group was given Lokomat training 3 times a week for 8 weeks. Both groups were evaluated after 4 and 8 weeks of treatment in terms of their walking ability, degree of lower limb spasm, lower limb motor functioning, balance and ability in the activities of daily life.Results:After 4 and 8 weeks the number of patients walking independently was significantly greater in the observation group. Their average stride frequency, step length on the affected side, support phase time and proportion of weight borne on the affected side were all significantly better than the control group′s averages. At both time points significantly more patients of the observation group had normal lower limb muscle tone. The observation group′s average Fugl-Meyer score, Berg Balance Scale score and modified Barthel Index score had improved significantly compared with those before the treatment, and were significantly better than the control group′s averages at the same time point. After 8 weeks of treatment the average walking speed of the observation group was faster than that of the control group.Conclusions:Lokomat training can significantly improve the walking ability of stroke survivors with lower limb spasm in the short term. Longer-term training can consolidate the effect and further improve the walking speed, motor function in the lower limbs, balance and even facility in daily life activities, as well as relieving spasm.

Effect of track body weight support walking training on lower limb motor function in stroke patients: based on ICF Core Set for Stroke / 中国康复理论与实践

ObjectiveTo evaluate the effect of track body weight support walking training on lower limb motor function in stroke patients using International Classification of Functioning, Disability and Health (ICF) Core Sets for Stroke. MethodsFrom April to October, 2021, 15 stroke patients from Wudang Mountain Hospital received track body weight support walking training everyday for 30 minutes, five times a week for four weeks. Before and after treatment, they were evaluated with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Berg Balance Scale (BBS), 6-minute Walking Test (6MWT), ICF Core Set for Stroke (gait), and three-dimensional gait analysis. ResultsAfter treatment, the ICF gait function qualifier, FMA-LE score, BBS score, the distance of 6MWT, gait speed, gait symmetry and and the maximum motion angle of hip and knee increased (|t| > 4.141, P < 0.01). ConclusionTrack body weight support walking training could improve the lower limb motor function and gait of stroke patients.

Effects of 5-aminolevulinic acid with iron supplementation on respiratory responses to graded cycling and interval walking training achievement in older women over 75 yrs.

BACKGROUND: Exercise training above a given intensity is necessary to prevent age-associated physical disability and diseases; however, the physical and psychological barriers posed by deteriorated physical fitness due to aging may hinder older people from performing daily exercise training. Because 5-aminolevulinic acid (ALA), a precursor of heme, reportedly improves mitochondrial function, we examined whether ALA, combined with sodium ferrous citrate (SFC) for enhancement, improved aerobic capacity and voluntary exercise training achievement in older women aged over 75 yrs. METHODS: The study was conducted using a placebo-controlled, double-blind crossover design. Fifteen women aged ~78 yrs. with no exercise habits underwent two trials for 7 days each where they performed interval walking training (IWT), repeating fast and slow speeds of walking for 3 min each, at >70% and at ~40% of peak aerobic capacity for walking, respectively, with ALA+SFC (100 and 115 mg/day, respectively) or placebo supplement intake (CNT), with a 12-day washout period. Before and after each trial, subjects underwent a graded cycling test while having their oxygen consumption rate (V·O2), carbon dioxide production rate (V·CO2), and plasma lactate concentration ([Lac-]p) measured. Furthermore, during the supplement intake period, exercise intensity for IWT was measured by accelerometry. RESULTS: In ALA+SFC, the increases in V·O2 and V·CO2 during the graded cycling test were attenuated (both, P < 0.01) with a 13% reduction in [Lac-]p (P = 0.012) while none of these attenuated responses occurred in CNT (all, P > 0.46). Furthermore, energy expenditure and time during fast walking for IWT were 25% (P = 0.032) and 21% (P = 0.022) higher in ALA+SFC than in CNT. CONCLUSION: Thus, ALA+SFC supplementation improved aerobic capacity and thus increased fast-walking training achievement in older women.

Effect of Rhythm of Music Therapy on Gait in Patients with Stroke.

AIM: This study aims to analyze the effects of rhythm of music therapy on gait in patients with ischemic stroke, and explore the value of music therapy in walking training in stroke. METHODS: The present study is a prospective clinical study. Sixty patients with ischemic stroke, who were admitted to our hospital from October 2017 to December 2018, were enrolled. These patients were divided into two groups, according to the method of the random number table, with thirty patients in each group: control group and study group. Patients in the control group received conventional drug therapy, rehabilitation training and walking training, while the patients in the study group were given music therapy on the basis of the above mentioned therapies for four weeks, during which Sunday was regarded as a rest day, and the music therapy was suspended. The main outcome measures included indexes in evaluating the walking ability of patients in these two groups. At each time point, the Fugl-Meyer Assessment (FMA), Berg Balance Scale (BBS) and stroke rehabilitation treatment satisfaction questionnaire were used. RESULTS: The results revealed that the stride length, cadence and maximum velocity were higher in patients in the study group, when compared to patients in the control group, at the second week and end of the therapy, and the difference in step length between the affected side and healthy side was significantly lower in the study group than in the control group. These differences were statistically significant (P < 0.05). In the second week of therapy and at the end of therapy, the FMA and BBS scores were higher in the study group than in the control group, and the difference was statistically significant (P < 0.05). The total satisfaction rate was higher in the study group than in the control group, and the difference was statistically significant (P < 0.05). CONCLUSION: Under the stimulation of music rhythm, applying music therapy to patients with ischemic stroke can improve their gait, walking ability, lower limb motor function, balance ability and treatment satisfaction.
