RESUMO

BACKGROUND: Stepping in place (SIP) is a useful locomotor training intervention. The purpose of this study was to investigate the effects of single auditory-cued SIP training on cortical excitability, rhythmic movements and walking ability in patients with Parkinson's disease(PD). METHODS: Cross-over randomized control trial. Each participant completed two interventions with at least one-week washout period in between: (1) SIP with concurrent auditory cues (AC condition) and (2) SIP without auditory cues (NC condition). RESULTS: In the primary outcome, the cortical silent period (CSP) duration increased (P = .005), whereas short intracortical inhibition (SICI) decreased after training (P = .001). Freezers demonstrated enhanced inhibition in the resting motor threshold and CSP duration. SICI and intracortical facilitation were modulated in both groups under the AC condition. In the secondary outcomes, the stepping variability decreased significantly (AC: P = .033; NC: P = .009), whereas walking cadence increased after training (AC: P = .019; NC: P = .0023). CONCLUSIONS: Auditory-cued SIP training improved the lower-limb movement variability and modulated the cortical excitability in patients with PD. Freezers may benefit more from this training than nonfreezers.

RESUMO

Objective: To investigate the influence of different variable combinations of the carrying system on gait and muscle fatigue during weight-bearing walking on both shoulders and back, and to optimize daily carrying experience. Methods: From September to December, 2018, 6 male college students were selected as subjects; the electromyographic signal of the anterior tibial muscle and plantar pressure were measured during weight-bearing walking under six different variable combinations of the carrying system (with the three variables of gravity center, single or double shoulders, and waist cushion), and a subjective evaluation test was performed for the degree of fatigue. The electromyographic data and plantar pressure data were processed and compared to evaluate behavior and fatigue. Results: Different variable combinations of the carrying system had significant influence on the degree of fatigue and gait (P<0.05). Both subjective and objective analyses found that the carrying system with different heights of gravity center and single-or double-shoulder carrying mode had great influence on human fatigue and walking gait, while the hardness of waist cushion had little influence. Compared with the other groups, the group with a high gravity center, a double-shoulder carrying mode, and a soft waist cushion had a significantly smaller slope of average electromyographic amplitude, a significantly larger slope of median frequency, and a significantly lower degree of plantar pressure curve disorder. Conclusion: The carrying system with a relatively high gravity center, a double-shoulder carrying mode, and a soft waist cushion can significantly relieve fatigue, with low influence on walking gait.

RESUMO

Introduction: The effects of hyperbaric oxygen (HBO2) therapy on sprains, ligament injuries, and muscle strains have been reported in several animal studies. In a dog model of compartment syndrome and in a rat contused skeletal muscle injury model, the significant effects of HBO2 therapy on the reduction of edema and muscle necrosis have been reported. In basic research HBO2 therapy stimulated fibroblast activity to improve the healing process. Because of this it expected that HBO2 therapy might improve focal edema and pain in the acute phase and accelerate the healing of injured tissues in athletes with a medial collateral ligament (MCL) injury of the knee. This study aimed to examine the short-term effects of HBO2 application subjectively, and the long-term effects of HBO2 therapy in Japanese professional or semi-professional rugby players with grade 2 MCL injury of the knee. Methods: Thirty-two professional or semi-professional rugby players with grade 2 MCL injury of the knee were investigated. First, in the HBO2 group (n=16), HBO2 therapy was performed during the acute phase. Visual analog scales (VASs) immediately before and after HBO2 therapy on the same day were compared. Next, we retrospectively evaluated the time to return to play in the HBO2 (n=16) and non-HBO2 (n=16) groups. Results: VAS scores for pain while walking immediately before and after HBO2 therapy on the same day were 37.4 ± 20.1 (mean ± standard deviation) and 32.4 ± 21.8, respectively (p⟨0.001). The VAS scores for pain while jogging were 50.7 ± 25.6 and 43.9 ± 25.0, respectively (p⟨0.001). The time to return to play was 31.4 ± 12.2 days in the HBO2 group and 42.1 ± 15.8 days in the non-HBO2 group, indicating a significant difference between the groups (p⟨0.05). Conclusion: HBO2 therapy may reduce pain and accelerate the return to play in athletes with grade 2 MCL injury of the knee in this non-randomized study.

RESUMO

BACKGROUND: Sedentary lifestyle leads to worse health outcomes with aging, including frailty. Older adults can benefit from regular physical activity, but exercise promotion in the clinical setting is challenging. OBJECTIVES: The objective of this clinical demonstration project was to implement a Geriatric Walking Clinic for older adults and determine whether this clinical program can lead to improvements in characteristics of frailty. DESIGN: This was a clinical demonstration project/quality improvement project. SETTING: Outpatient geriatrics clinic at the South Texas Veterans Health Care System (STVHCS). PARTICIPANTS: Older Veterans, aged ≥60 years. INTERVENTION: A 6-week structured walking program, delivered by a registered nurse and geriatrician. Patients received a pedometer and a comprehensive safety evaluation at an initial face-to-face visit. They were subsequently followed with weekly phone calls and participated in a final face-to-face follow-up visit at 6 weeks. MEASUREMENTS: Grip strength (handheld dynamometer), gait speed (10-ft walk), Timed Up and Go (TUG), and body mass index (BMI) were assessed at baseline and follow-up. Frailty status for gait speed was assessed using Fried criteria. RESULTS: One hundred eighty five patients completed the program (mean age: 68.4 ±7 years, 88% male). Improvements from baseline to follow-up were observed in average steps/day, gait speed, TUG, and BMI. Improvement in gait speed (1.13 ±0.20 vs. 1.24 ± 0.23 meter/second, p<0.0001) resulted in reduced odds of meeting frailty criteria for slow gait at follow-up compared to the baseline examination (odds ratio = 0.31, 95% confidence interval: 0.13-0.72, p = 0.01). CONCLUSIONS: Our findings demonstrate that a short duration, low-intensity walking intervention improves gait speed and TUG. This new clinical model may be useful for the promotion of physical activity, and for the prevention or amelioration of frailty characteristics in older adults.

RESUMO

Gait disturbance is a major symptom in patients with multiple sclerosis. The Expanded Disability Status Scale (EDSS) was first used in clinical trials of multiple sclerosis for the assessment of disability, however it has become more and more widely used in clinical practice as well. Nowadays its use is essential in application of the new diagnostic criteria, the new clinical form classification and in monitoring the efficacy of therapies. EDSS is based on a standardised neurological examination, but focuses on those symptoms that are frequent in multiple sclerosis. Based on the examination it assesses seven functional systems: visual, brainstem, pyramidal, cerebellar, sensory, bowel-bladder and cerebral functions. EDSS scores can be determined based on the scores given in the functional systems and on testing the walking distance. In newer versions the "Ambulation score" has been added. This chapter clarifies the scores based on the maximal walking distance and the need for a walking aid to walk this distance. The Neurostatus/EDSS training method improves the reproducibility of the standardised neurological examination that forms the basis of the EDSS scoring. Of the tests assessing walking, the Timed-25 Foot Walk Test and the self-administered 12-Item Multiple Sclerosis Walking Scale are suitable for routine evaluation of walking performance. An increase of more than 20% in the Timed-25 Foot Walk may be considered a significant change in gait.

RESUMO

Evidence suggests that mental health is associated with multiple factors such as physical activity, sedentary behavior, and physical function in older adults. The present study used latent profile analysis to identify classes of older adults based on their health profile among a representative sample of Korean older adults with hypertension. Differences in mental health between these classes were also examined.Seven hundred and sixty seven participants (mean age = 70.23, SD = 6.08; men 45.6%) were included in the analysis.There were 3 latent classes (class 1: a physically inactive lifestyle with low physical function and body perception; class 2: a physically moderate lifestyle with moderate physical function and low body perception; class 3: a physically active lifestyle with high physical function and body perception). According to class comparisons, older adults in class 3 had significantly lower anxiety/depression levels than classes 1 and 2. Older adults in class 3 had significantly lower stress levels than class 1.It is possible that among older adults, having a positive attitude of one's body shape may also be important for improving anxiety/depression along with having a physically active lifestyle and maintaining physical function.

RESUMO

BACKGROUND: The potential for full rehabilitation following amputation among end-stage renal disease patients is poor. OBJECTIVES: To evaluate the functional outcomes and survival among amputees treated with hemodialysis at the end of the rehabilitation procedure. METHODS: We recruited 46 patients after lower limb amputation. Of these individuals, 19 (41.3%) were treated with dialysis and 27 (58.7%) were non-dialysis-dependent patients (NDDP). Both groups were divided into three sub-groups according to their independence with regard to activities of daily living (ADL) and their ability to walk with prostheses. RESULTS: The survival of lower limb amputees treated with dialysis was shorter compared to NDDP. Survival after amputation among the NDDP who were fully or partially independent in ADL and with regard to mobility, was longer compared to the non-mobile amputees as with the patients treated with dialysis. CONCLUSIONS: Survival was significantly longer in lower limb amputees NDDP and shorter in patients who did not achieve a certain level of functioning.

RESUMO

Most studies on patients with normal pressure hydrocephalus (NPH) regard pre-post Tap test and long-term follow-up after shunt surgery. Quantitative and qualitative assessment tools specific to rehabilitation medicine can provide an objective measurement of the benefit of the neurosurgical intervention at 1-month follow-up. The aim of this retrospective study was to assess the early benefit of the ventriculoperitoneal shunt with low or medium pressure valve on the gait capacity of persons with NPH, one month after surgery. This is a retrospective study reviewing 19 inpatients with NPH who underwent neurosurgery for ventriculoperitoneal shunt with low or medium pressure valve, one month after a positive result on a tap test, in a 5-year period. The assessments regarding the gait abilities were performed 24 hours before the surgical intervention and one month after surgery. Assessment tools used were: the 3 meters Timed Up and Go Test (TUG), the 10 Meters Walking Test (10MWT) and the Berg Balance Scale. A positive response to the tap test predicted improvements of gait and balance in patients with NPH after shunt surgery. Best results in regards to gait and balance are achieved when early diagnosis and intervention are performed. Complex comorbidities generate and enhance significant and persistent gait impairment.

RESUMO

AIM: The study was aimed at assessing efficacy and safety of treatment with Aducil® (cilostazol) compared with Trental® 400 in patients with moderate-to-severe intermittent claudication due to peripheral atherosclerosis. PATIENTS AND METHODS: The study included a total of one hundred and forty-five 36-to-75-year-old patients. The participants were distributed into 2 groups according to the inclusion/exclusion criteria in a 2 to 1 proportion: patients in group 1 received Aducil® 100 mg BID, in group 2 - Trental® 400 TID for 12 weeks. 142 subjects completed the protocol. RESULTS: Analysis of the effectiveness of treatment according to the primary criterion showed a better effectiveness of Aducil® as compared with Trental® 400. Subjects who received Aducil® had a higher increase in the absolute maximum walking distance after 12 weeks of treatment as compared with those taking Trental® 400: 126±110 m versus 45±39 m, respectively (р<0.001). Subjects who received Aducil® had a statistically significant improvement in quality of life parameters such as physical and mental health components according to the SF-36 questionnaire after 12 weeks of treatment (р≤0.01). Subjects in Aducil® group had better quality of life with an increase from 34 to 40 points according to the physical component score, while patients in Trental® 400 group demonstrated minor positive changes (from 35 to 37 points); mean mental component score increased from 45 to 48 points in Aducil® group as compared with an increase from 45 to 47 points in Trental® 400 group. While self-reported physical health status was similar between the groups at baseline, subjects in Aducil® group reported better physical functioning after treatment (р=0.016). Two adverse events were registered in two subjects in Aducil® group. CONCLUSION: Analysis of the study endpoints demonstrated that Aducil® had better treatment effectiveness in patients with chronic lower limb ischemia stage IIB according to the classification of A.V. Pokrovsky-Fontaine as compared with Trental® 400, while the safety profile and drug tolerance were similar between the two.

RESUMO

The authors tested 4 young healthy subjects walking with a powered knee exoskeleton to determine if it could reduce the metabolic cost of locomotion. Subjects walked with a backpack loaded and unloaded, on a treadmill with inclinations of 0° and 15°, and outdoors with varied natural terrain. Participants walked at a self-selected speed (average 1.0 m/s) for all conditions, except incline treadmill walking (average 0.5 m/s). The authors hypothesized that the knee exoskeleton would reduce the metabolic cost of walking uphill and with a load compared with walking without the exoskeleton. The knee exoskeleton reduced metabolic cost by 4.2% in the 15° incline with the backpack load. All other conditions had an increase in metabolic cost when using the knee exoskeleton compared with not using the exoskeleton. There was more variation in metabolic cost over the outdoor walking course with the knee exoskeleton than without it. Our findings indicate that powered assistance at the knee is more likely to decrease the metabolic cost of walking in uphill conditions and during loaded walking rather than in level conditions without a backpack load. Differences in positive mechanical work demand at the knee for varying conditions may explain the differences in metabolic benefit from the exoskeleton.

RESUMO

OBJECTIVE: To determine the safety and efficacy of aerobic exercise on activities of daily living in the subacute phase after stroke. DESIGN: Multicentre, randomised controlled, endpoint blinded trial. SETTING: Seven inpatient rehabilitation sites in Germany (2013-17). PARTICIPANTS: 200 adults with subacute stroke (days 5-45 after stroke) with a median National Institutes of Health stroke scale (NIHSS, range 0-42 points, higher values indicating more severe strokes) score of 8 (interquartile range 5-12) were randomly assigned (1:1) to aerobic physical fitness training (n=105) or relaxation sessions (n=95, control group) in addition to standard care. INTERVENTION: Participants received either aerobic, bodyweight supported, treadmill based physical fitness training or relaxation sessions, each for 25 minutes, five times weekly for four weeks, in addition to standard rehabilitation therapy. Investigators and endpoint assessors were masked to treatment assignment. MAIN OUTCOME MEASURES: The primary outcomes were change in maximal walking speed (m/s) in the 10 m walking test and change in Barthel index scores (range 0-100 points, higher scores indicating less disability) three months after stroke compared with baseline. Safety outcomes were recurrent cardiovascular events, including stroke, hospital readmissions, and death within three months after stroke. Efficacy was tested with analysis of covariance for each primary outcome in the full analysis set. Multiple imputation was used to account for missing values. RESULTS: Compared with relaxation, aerobic physical fitness training did not result in a significantly higher mean change in maximal walking speed (adjusted treatment effect 0.1 m/s (95% confidence interval 0.0 to 0.2 m/s), P=0.23) or mean change in Barthel index score (0 (-5 to 5), P=0.99) at three months after stroke. A higher rate of serious adverse events was observed in the aerobic group compared with relaxation group (incidence rate ratio 1.81, 95% confidence interval 0.97 to 3.36). CONCLUSIONS: Among moderately to severely affected adults with subacute stroke, aerobic bodyweight supported, treadmill based physical fitness training was not superior to relaxation sessions for maximal walking speed and Barthel index score but did suggest higher rates of adverse events. These results do not appear to support the use of aerobic bodyweight supported fitness training in people with subacute stroke to improve activities of daily living or maximal walking speed and should be considered in future guidelines. TRIAL REGISTRATION: ClinicalTrials.gov NCT01953549.

RESUMO

BACKGROUND: Assistance systems serving the locomotion of older people interact in many ways with the culture of a society. Since early modern times at the latest, walking aids were tantamount to human frailty; however, the cane also symbolized governmental power or reputation. Nowadays, the cane, the wheelchair, and the rollator have not only a functional significance in terms of a better mobility, they also enable people to take an active part in social life. OBJECTIVE: This study aimes at tracing back these provisional insights into the history of civilization and thereby analyze the roots, new forms and pictures of the handling and metaphors of these assistance systems. The goal in the context of this special issue is to decipher a central textual and pictorial symbol of old age, comparing it with more recent symbols of assistance in old age. MATERIAL AND METHODS: Methodologically, the text combines approaches of philology and history of medicine with those of the history of art. It analyzes (after a brief retrospection of ancient times and the Middle Ages) by means of textual and pictorial sources from the sixteenth to the twenty-first centuries the historical development of these aids of locomotion for older people. Additionally, it explores the cultural relevancy of these assistance systems. RESULTS AND DISCUSSION: In history the medical profession paid relatively late and then only minor attention to the assistive systems analyzed here. Its semantic diversity is closely related to the age roles and stereotypes of age prevailing in certain epochs. The more the respective assistive tool is used by old people, the more suitable it is as a symbol of old age and the more biased and negative the semantic connotation seems to be. The development of a symbol of age connoting frailty, at present symbolized most clearly by the rollator, tends to refer to a pejorative image of age in a society. The cultural historical analysis suggests that a contrasting development will only be possible when the assistive systems will again fulfil a diversity of alternative functions and semantics.

RESUMO

Introduction: This study evaluates characteristics and risk factors of traumatic spinal injuries (TSIs) treated at a trauma center in Abuja, Nigeria. TSIs are a global concern. They are frequently disabling, leading to economic, workforce, and quality of life strain. Little is known of the epidemiology of TSIs in Nigeria. Methods: Data were collected from National Hospital Abuja's trauma registry on 3025 patients treated at the hospital between 2014 and 2017. Patient characteristics were compared between spinal and nonspinal injury groups. Multiple logistic regression was used to identify risk factors of TSIs. Results: 15% (452) of all injuries were spinal. Road traffic crashes were a significantly greater cause of spinal (77.4%) than nonspinal (59.4%) injuries (p<0.0001). Pedestrians were involved in 19% (356) of total crashes, occupying a significantly larger proportion of spinal (18.6%) than nonspinal (10.6%) injuries (p<0.0001). Three variables were modeled as risk factors of crash-related TSIs: mode of transportation, age, and gender. Only mode of transportation demonstrated statistical significance, with involvement as a pedestrian showing an adjusted odds ratio of 1.38 (95% confidence interval: 1.03-1.85, p=0.0329). Conclusion: Determining characteristics and risk factors of TSIs is an essential step in addressing this health concern in Nigeria. Crashes are a significant cause of TSIs, and a quarter of TSI patients involved in a crash are pedestrians. Involvement in a crash as a pedestrian is associated with high risk of TSI. These results can help guide both the development of spinal injury prevention policies and the allocation of resources.

RESUMO

Physical inactivity is a social problem related to health. Based on the concept of health communication, this study aims to construct a mechanism to provide continuous information to improve physical activity. We built a "home digital signage system" which consists of a function of collecting the localized information from the websites and distributing to the tablets. The results of the introduction of this system have been suggested to promote walking by increasing media exposure.

RESUMO

AIM: To study the efficacy of the developed approach to the specialized Spa-rehabilitation of motor disorders in patients with cerebral palsy (spastic diplegia). MATERIAL AND METHODS: The study included 86 patients (45 (52,33%) women and 41 (47.67%) men), aged from 10 to 16-years, mean 13,02±2,13. All patients were divided into 2 groups depending on the method of treatment. RESULTS AND CONCLUSION: Administration of minimally invasive procedures during the course of rehabilitation can effectively restore the volume of movements in the limbs, stimulate motor development in children and form a new stereotype of walking. An analysis of the follow-up data one year after the treatment confirms the efficacy of the proposed approach to rehabilitation.

RESUMO

In order to detect freezing of gait of Parkinson's patients automatically, a system based on inertial measurement unit to detect freezing of gait for Parkinson's patients is established. The two inertial measurement units are respectively fixed on the left and right ankles of the patient to be measured, the freezing index is calculated by windowed Fourier transform, the freezing threshold is calculated based on the freezing index during normal walking, and the freezing index and the freezing threshold are compared to complete the detection of freezing of gait. The experimental results show that the number of freezing of gait occurrences in Parkinson's patients is accurately detected, and it has high sensitivity and specificity, which can assist doctors to objectively assess the patient's condition.

RESUMO

BACKGROUND: Children's ability to control the speed of gait is important for a wide range of activities. It is thought that the ability to increase the speed of gait for children with cerebral palsy (CP) is common. This study considered 3 hypotheses: (1) most ambulatory children with CP can increase gait speed, (2) the characteristics of free (self-selected) and fast walking are related to motor impairment level, and (3) the strategies used to increase gait speed are distinct among these levels. METHODS: A retrospective review of time-distance parameters (TDPs) for 212 subjects with CP and 34 typically developing subjects walking at free and fast speeds was performed. Only children who could increase their gait speed above the minimal clinically important difference were defined as having a fast walk. Analysis of variance was used to compare TDPs of children with CP, among Gross Motor Function Classification System (GMFCS) levels, and children in typically developing group. RESULTS: Eight-five percent of the CP group (GMFCS I, II, III; 96%, 99%, and 34%, respectively) could increase gait speed on demand. At free speed, children at GMFCS I and II were significantly faster than children at GMFCS level III. At free speed, children at GMFCS I and II had significantly greater stride length than those at GMFCS levels III. At free speed, children at GMFCS level III had significantly lower cadence than those at GMFCS I and II. There were no significant differences in cadence among GMFCS levels at fast speeds. There were no significant differences among GMFCS levels for percent change in any TDP between free and fast walking. DISCUSSION: Almost all children with CP at GMFCS levels I and II can control the speed of gait, however, only one-third at GMFCS III level have this ability. This study suggests that children at GMFCS III level can be divided into 2 groups based on their ability to control gait speed; however, the prognostic significance of such categorization remains to be determined. LEVEL OF EVIDENCE: Diagnostic level II.

RESUMO

BACKGROUND: Affective responses experienced during exercise are a significant determinant on exercise adherence. We have previously demonstrated that consumption of New Zealand (NZ) blackcurrants preserves cognition by attenuating the feeling of fatigue. This positive affective response correlated with the ability of blackcurrant polyphenols to support monoamine neurotransmission via inhibition of monoamine oxidase-B (MAO-B) activity. Here we explore how the consumption of a NZ blackcurrant juice (BJ) influenced affective responses and potential ergogenic action on the motivation to adhere to a low impact walking exercise. METHODS: In a parallel randomized controlled study (Trial registration #: ACTRN12617000319370p, registered 28th February 2017, http://www.anzctr.org.au/ ), 40 healthy sedentary male and female participants drank a BJ or matched placebo (PLA) (n = 20 per group), 1 h prior to a self-motivated treadmill walk, where heart rate and affective responses (exertion [ES] or feeling / mood [FS]) scores) were recorded at 3 or 5 min intervals. Blood glucose, lactate, malondialdehyde (MDA) and platelet MAO-B activity were measured pre- and post-exercise and comparisons were conducted using with Student's t-tests. Subjective data were analysed using 2-way ANOVA with appropriate post hoc tests. RESULTS: Consuming a BJ 1 h prior to exercise caused a 90% decline in platelet MAO-B activity. The exercise had no significant (p > 0.05) effect on blood lactate, glucose or plasma MDA levels. Assessment of affective responses over the first 60 mins (adjusting for participant drop-out) revealed a time-dependent ES increase in both groups, with ES reported by participants in the BJ group consistently lower than those in the PLA group (p < 0.05). FS declined in PLA and BJ groups over 60 mins, but an inverse relationship with ES was only observed within the PLA group (r2 = 0.99, p = 0.001). Whilst the average time walked by participants in the BJ group was 11 mins longer than the PLA group (p = 0.3), and 30% of the BJ group achieving > 10 km compared to only 10% for the PLA group (p = 0.28), statistical significance was not achieved. CONCLUSION: Our findings demonstrate that drinking a polyphenolic-rich NZ blackcurrant juice 1 h prior to exercise supports positive affective responses during a self-motivated exercise.

RESUMO

Walking and running have fundamentally different biomechanics, which makes developing devices that assist both gaits challenging. We show that a portable exosuit that assists hip extension can reduce the metabolic rate of treadmill walking at 1.5 meters per second by 9.3% and that of running at 2.5 meters per second by 4.0% compared with locomotion without the exosuit. These reduction magnitudes are comparable to the effects of taking off 7.4 and 5.7 kilograms during walking and running, respectively, and are in a range that has shown meaningful athletic performance changes. The exosuit automatically switches between actuation profiles for both gaits, on the basis of estimated potential energy fluctuations of the wearer's center of mass. Single-participant experiments show that it is possible to reduce metabolic rates of different running speeds and uphill walking, further demonstrating the exosuit's versatility.
