OBJECTIVE: To assess the clinical effectiveness of the Odstock dropped foot stimulator by analysis of its effect on physiological cost index (PCI) and speed of walking. This functional electrical stimulation (FES) device stimulates the common peroneal nerve during the swing phase of gait. DESIGN: A retrospective study of patients who had used the device for 4 1/2 months. SUBJECTS: One hundred fifty-one patients with a dropped foot resulting from an upper motor neuron lesion. SETTING: A medical physics and biomedical engineering department of a district general hospital specializing in the clinical application of FES and a neurophysiotherapy department at a separate hospital. MAIN OUTCOME MEASURES: Changes in walking speed and effort of walking, as measured by PCI over a 10-meter course. RESULTS: There was a 92.7% compliance with treatment. Stroke patients showed a mean increase in walking speed of 27% (p<.01) and reduction in PCI of 31% (p<.01) with stimulation, and changes of 14% (p<.01) and 19% (p<.01), respectively, while not using the stimulator. Multiple sclerosis patients gained similar orthotic benefit but no "carry-over." CONCLUSIONS: The measured differences in walking with and without stimulation were statistically significant in the stroke and multiple sclerosis groups. In this study use of the stimulator improved walking. Those with stroke demonstrated a short-term "carry-over" effect. 相似文献

ObjectivesTo explore experiences, preferences and choices relating to the use of ankle foot orthoses (AFOs) and functional electrical stimulation (FES) for foot-drop by people who have suffered a stroke and their carers, with the aim of informing clinical decision-making. DesignSemi-structured interviews explored individual experiences through a phenomenological approach. The Interpretative Phenomenological Analysis framework was used to enable organisation and interpretation of qualitative interview data. SettingParticipants who had used both transcutaneous FES and one of several types of AFO were recruited from a single FES clinic. ParticipantsNine people who had suffered a stroke and four carers were recruited purposively, including people between 2 and 9 years post stroke, with different degrees of difficulty in walking. ResultsParticipants described experiences, preferences and choices relating to AFO and FES use. All but one person expressed a preference for FES use and related this to being able to move the ankle more freely; walk more normally, safely and independently; and greater comfort. Several people also used AFOs when the FES equipment failed, when travelling and near water. One person rationed their use of FES on a daily basis due to allergic reactions. ConclusionsThe consensus in this sample demonstrated positive and negative experiences of both FES and AFO use. Participants weighed up the pros and cons, and despite predominant preferences for FES, many also used AFOs due to some drawbacks of FES. Further research and development are required to reduce drawbacks and further explore users’ experiences. 相似文献

Purpose: A constructivist phenomenological study explored impacts of ankle foot orthoses (AFOs) or functional electrical stimulation (FES) on people with foot-drop from multiple sclerosis (MS). Method: Focus groups following topic guides were analysed using interpretative phenomenological analysis, with researcher reflexivity, participant verification and peer checking of analysis. Participants with sustained use of the devices (under 2 y) were invited from two quantitative studies that (a) investigated immediate FES effects ( n?=?12) and (b) compared habitual use of AFO ( n?=?7) or FES ( n?=?6). Two focus groups addressed AFO ( n?=?4) and FES ( n?=?6) experiences. Results: Similar numbers of positive and negative aspects were described for AFO and FES. Both reduced fatigue, improved gait, reduced trips and falls, increased participation, and increased confidence; greater balance/stability was reported for AFOs, and increased walking distance, fitness and physical activity for FES. Barriers to both included avoiding reliance on devices and implications for shoes and clothing; a non-normal gait pattern was reported for AFO, and difficulties of application and limitations in the design of FES. However, participants felt the positives outweighed the negatives. Conclusions: Participants felt benefits outweighed the drawbacks for AFO and FES; greater understanding of user preferences and satisfaction may increase likelihood of usage and efficacy. - Implications for Rehabilitation
Interventions to reduce the impacts of foot-drop in people with multiple sclerosis (MS) are important to optimise physical activity participation and participation in life; they include ankle foot orthoses (AFOs) and functional electrical stimulation (FES). Research is lacking regarding user satisfaction and perceived outcomes, therefore, two separate focus groups were conducted from a constructivist phenomenological perspective to explore the impacts of AFOs (n?=?4) and FES (n?=?6) on people with foot-drop from MS. Some similar positive aspects of AFO and FES use were described, including reduced fatigue, improved gait and fewer trips and falls, while common barriers included finding the device cumbersome, uncomfortable, and inconvenient, with some psychological barriers to their use. On balance, the impacts of the devices on improving activities and participation were more important for participants than practical barriers, highlighting the importance of combining understanding of individual experiences and preferences with clinical decision-making when prescribing a device to manage foot-drop. 相似文献

[Purpose] This study sought to identify the gait aspects according to the FES
stimulation position in stroke patients during gait training. [Subjects and Methods] To
perform gait analysis, ten stroke patients were grouped based on 4 types of gait
conditions: gait without FES stimulation (non-FES), gait with FES stimulation on the
tibialis anterior (Ta), gait with FES stimulation on the tibialis anterior and quadriceps
(TaQ), and gait with FES stimulation on the tibialis anterior and gluteus medius (TaGm).
[Results] Based on repeated measures analysis of variance of measurements of gait aspects
comprised of gait speed, gait cycle, and step length according to the FES stimulation
position, the FES stimulation significantly affected gait aspects. [Conclusion] In
conclusion, stimulating the tibialis anterior and quadriceps and stimulating the tibialis
anterior and gluteus medius are much more effective than stimulating only the tibialis
anterior during gait training in stroke patients using FES.Key words: Stroke, FES, Gait 相似文献

OBJECTIVES: To explore the impact of two methods of post-hospital stroke rehabilitation on both carers' perceptions of the health services offered and their quality of life. SETTING: East Dorset Health Authority. SUBJECTS: Forty-six informal carers were recruited from a sample of 106, initially identified from stroke patients participating in a larger randomized controlled trial. DESIGN: Qualitative methods. METHODS: Semi-structured interviews were used at baseline and six months to explore carers' perception of a good therapy, the advantages and disadvantages of the different services and their fulfilment with the services. In-depth thematic analysis was carried out to explore the impact of the two different methods of service delivery on carers' quality of life. RESULTS: Day hospitals provided carers with respite opportunities, whilst domiciliary stroke teams provided carers with better educational opportunities to be involved in therapy. No qualitative difference was found in the impact that the different services had on carers' quality of life, which were influenced by factors such as the degree of disruption that caring had on their lives, the loss of a shared life and the availability of social support. Ultimately, carers saw the services as providing benefit for survivors and not themselves. CONCLUSIONS: Domiciliary stroke teams provided informal stroke carers with skills that could help improve postdischarge stroke rehabilitation amongst stroke survivors. Informal carers also benefited from the respite elements of day hospital. A mixed model using both domiciliary care and day hospital care, could provide carers with the benefits of education, convenience and respite. 相似文献

Functional electrical stimulation (FES) can improve the gait of stroke patients by stimulating the peroneal nerve in the swing phase of the affected leg, causing dorsiflexion of the foot that allows the toes to clear the ground. A sensor can trigger the electrical stimulation automatically during the stroke gait. We previously used a heel sensor system, which detects the contact pressure of the heel, in FES to correct foot drop gait. However, the heel sensor has disadvantages in cosmetics and durability. Therefore, we have replaced the heel sensor with an acceleration sensor that can detect the swing phase based on the acceleration speed of the affected leg, using a machine learning technique (Neural Network). We have used a signal for heel contact in a gait using the heel sensor before training with the Neural Network. The accuracy of the Neural Network detector was compared with a swing phase detector based on the heel sensor. The Neural Network detector was able to detect similarly the swing phase in the heel sensor. The largest difference in timing of the swing phase was less than 60 milliseconds in normal subjects and 80 milliseconds in stroke patients. We were able to correct foot drop gait using FES with an acceleration sensor and Neural Network detector. The present results indicate that an acceleration sensor positioned on the thigh, which is cosmetically preferable to systems in which the sensor is farther from the entry point of the electrodes, is useful for correction of stroke gait using FES. 相似文献

In Australia, more than 346,000 individuals who experience a stroke return to living in their homes with varying degrees of disability. They rely on emotional and physical support from informal carers, typically family members. Informal carers have an indispensable role in patient care poststroke, and the ability of carers to manage this role effectively is crucial for stroke survivors to be able to return home. The aim of this study was to examine the impact of the caring role on carers of stroke survivors, particularly the services provided and the levels of depression and well-being experienced. The study used a longitudinal design incorporating survey methods. Stroke survivors were assessed for functional ability, quality of life, and depression using three assessment tools: the Stroke Impact Scale, World Health Organization Quality of Life-BREF scale, and Zung Self-Rating Depression Scale. A total of 26 people were surveyed: 13 stroke survivors and their 13 carers. Carer knowledge of stroke support services was also explored. Information was collected by using survey methods and structured interviews at 3 weeks and at 3 months postdischarge. The main finding was that depression scores for carers and stroke survivors were below Australian norms at both assessment time points. The major concern identified by carers was poor follow-up procedures for initiating rehabilitation in the home. This study highlighted that a lack of appropriate discharge planning, in conjunction with early discharge of stroke survivors, can have an impact on the rehabilitation process and place increased and unrealistic demands on carers. 相似文献

OBJECTIVE: There is limited research on the relationship between chronic pain and occupation. This phenomenological research study explored the lived occupational experiences of people who have chronic pain. METHOD: Via demographic questionnaires, semistructured interviews, and field notes, data were collected on 13 participants with various types of pain. RESULTS: Thematic analysis yielded one main theme: "Chronic Pain Is Life Changing." The following subthemes also emerged: "Chronic Pain Triggers Emotional Distress"; "Chronic Pain Reveals the Strength of Relationships"; "Chronic Pain and Occupation Are Reciprocally Related Forces"; and "Chronic Pain Elicits Innovative Adaptive Responses." Study participants reported experiencing myriad troubling emotions; however, they resourcefully modified their routines and tasks and found enhanced meaning in favored occupations. CONCLUSIONS: This study illuminates the importance of therapeutic listening, the innovativeness of people who have chronic pain, and the possible therapeutic potential of occupation. 相似文献

It is well known that patients who have suffered a stroke have problems with balance and have feelings of unsteadiness. The aim of this study was to analyse the correlation between how patients estimate their perceived confidence in task performance without falling and the objective assessment of balance made by a physiotherapist, and whether the Falls Efficacy Scale (FES(S)) is to be recommended for use in patients in the acute phase of stroke. Sixty patients divided into two groups assessed their belief to perform daily life activities without fear of falling using the FES(S) and were assessed by using the Berg Balance Scale (BBS) and Timed Up and Go (TUG) by a physiotherapist. Group 1 assessed themselves before, whereas Group 2 assessed themselves after the objective assessment. The correlation between the FES(S) and the TUG was moderate to good, but these two scales consider different aspects and dimensions of balance, ability, and belief and are therefore not interchangeable. The correlation between FES(S) and BBS was low to moderate. The conclusion of this study was that the FES(S) is not to be recommended as a single measurement in the acute phase of stroke because it does not measure actual balance function. 相似文献

BackgroundFunctional electrical stimulation (FES) for patients with stroke and foot drop is an alternative to ankle foot orthoses. Characteristics of FES responders and nonresponders have not been clarified.Objectives(1) To investigate the effects of treatment with FES on patients with stroke and foot drop and (2) to determine which factors may relate to responders and nonresponders.DesignMulticenter, nonrandomized, prospective study.SettingMulticenter clinical trial.ParticipantsParticipants included those who experienced foot drop resulting from stroke, were older than 20 years, and could provide consent to participate; they were enrolled from hospitals between January 2013 and September 2015 and performed rehabilitation with FES.MethodsStroke Impairment Assessment Set Foot-Pat Test (SIAS-FP), Fugl-Meyer Assessment for Lower Extremity (FMA-LE), Modified Ashworth scale (MAS) for ankle joint dorsiflexion and plantar flexion muscles, range of motion (ROM) for ankle joint, 10-m walking test (10mWT), Timed Up & Go test (TUG), and 6-minute walking test (6MWT) were evaluated pre- and postintervention. Age, gender, type of stroke, onset times of stroke, paretic side, Brunnstrom stage of the lower extremity (Br. stage-LE), Functional Independence Measure (FIM), Functional Ambulation Category (FAC), poststroke months, number of interventions, total hours of interventions, and whether a brace was used were extracted from patients’ medical records and collected on the physiological examination day.Main Outcome MeasurementsThe authors examined 10mWT and age, gender, type of stroke, onset times of stroke, paretic side, Br. stage-LE, FIM, FAC, poststroke months, number of interventions, total hours of interventions, whether a brace was used, SIAS-FP, FMA-LE, MAS, ROM, TUG, and 6MWT before intervention. Participants were divided into nonresponders and responders with a change in 10mWT of <0.1 and ≥0.1 m/s, respectively. Single and multiple regression analyses were used for data analysis. Additionally, the changes between groups were compared.ResultsFifty-eight responders and 43 nonresponders were enrolled. The between-group differences, compared for changes between pre- and postintervention, were significant in terms of changes in SIAS-FP (P = .02), 10mWT (P < .001), 10-m gait steps (P < .001), TUG (P = .04), and 6MWT (P = .006). In the adjusted regression model, gender (odds ratio [OR], 3.92; 95% confidence interval [CI], 1.426-12.25; P = .007), number of interventions (OR, 1.028; 95% CI, 1.003-1.070; P = .03), and active ankle joint dorsiflexion ROM (OR, 1.047; 95% CI, 1.014-1.088; P = .005) remained significant.ConclusionThe factors related to 10mWT showing changes beyond the minimal clinically important difference were found to be patient gender, number of interventions, and active ankle joint dorsiflexion ROM before intervention. When patients with stroke who have greater active ankle joint ROM, and are female, use FES positively, they may benefit more from using FES.

Background and Purpose. This study tested the safety and ability of subjects with chronic hemiplegia to tolerate intensive training using a motorized cycle combined with functional electrical stimulation (FES) system. Methods. A case series of 10 subjects with chronic stroke participated in 30‐minute three times per week cycling on a stationary motorized cycling system combined with FES (RT300 TM). The stimulation activated the dorsal and plantar flexors, the quadriceps and the hamstrings using four channels and a stimulation pattern that assisted cycling motion of the paretic lower limb. Patients were instructed to cycle as close as possible to 60 rpm and the resistance to cycling was gradually increased using a computer‐based algorism. The training lasted eight weeks. Results. All 10 participants completed the training without adverse reactions to the training or the FES. The kcal utilized during the training increased significantly ( p = 0.0003) between session 1 (2.2 ± 0.47), session 12 (4.3 ± 1.2) and session 24 (7.5 ± 1.8). Peak pedaling power increased from 6.5 ± 0.5 W pre‐training to 18.0 ± 5.4 W post‐training. Locomotion variables that improved significantly were time to complete the get up and go test (45.4 ± 54.9 seconds vs. 34.0 ± 31.8 seconds) a 24.6% improvement ( p = 0.03) and gait velocity, which increased 25.0% from 0.4 ± 0.3 m/sec to 0.5 ± 0.4 m/sec ( p = 0.01). Conclusion. Using a motorized cycle combined with FES intensive training appears safe and can be tolerated by patients with chronic stroke of wide age range, diverse severity of cardio‐pulmonary deconditioning, motor loss and locomotor deficits.

PURPOSE: To calculate the impact of stroke in Italy in 1998, expressed in terms of disability adjusted life years (DALYs) according to the WHO Global Burden of Disease (GBD) Study. METHOD: The data on first-ever stroke incidence (FES), remission rate and case fatality derived from the health information system and a research on post-FES disability of the Friuli Venezia-Giulia (FVG) Region, were used to compute the years of life lived with disability (YLDs), which were added to the years of life lost due to premature mortality (YLLs), calculated from stroke mortality data, to obtain the DALYs. The results were extrapolated to the rest of Italy after examination of national stroke registries data. RESULTS: Standardized estimated incidence of FES in FVG in 1998 was lower (135 cases of FES per 100 000 inhabitants) than that reported in other published national and international studies. Estimated case fatality rate and distribution of post-FES disability did not differ from other similar studies. About 100 000 YLLs and 273 000 YLDs due to FES were estimated in 1998 for Italy. CONCLUSIONS: The estimated proportion of the YLDs on total DALYs (27%) is comparable with that obtained in the EURO-A group (the European area including Italy) of the GBD 2000 Study (31%), and the Australian BoD Study (35%). 相似文献

van Swigchem R, Weerdesteyn V, van Duijnhoven HJ, den Boer J, Beems T, Geurts AC. Near-normal gait pattern with peroneal electrical stimulation as a neuroprosthesis in the chronic phase of stroke: a case report.In recent years, the use of functional electrical stimulation (FES) of the peroneal nerve has increased as an alternative for an ankle-foot orthosis (AFO) to treat stroke-related drop foot. We present a chronic stroke patient demonstrating an almost normal gait pattern with peroneal FES as a neuroprosthesis. A 60-year-old survivor of a right hemisphere infarction 21 months ago, who regularly used a polypropylene AFO, was provided with a surface-based peroneal FES device for severe drop foot. In a second instance, he received an implanted FES system because of skin problems with the surface stimulator. With both FES devices, the patient achieved an adequate foot elevation. Moreover, his hip and knee flexion angles during walking increased to normal values and his ankle push-off power increased. His gait pattern became almost symmetrical and less variable than with the AFO. Furthermore, his ability to avoid a sudden obstacle improved to normal values with FES. Our patient showed benefits from peroneal FES beyond what can be attributed to improved foot lift alone. With regard to the potential working mechanisms underlying this response to FES, biomechanical benefits related to improved ankle push-off are suggested as the main mechanism. 相似文献

[Purpose] The purpose of this study was to determine the effects of brain-computer
interface (BCI)-based functional electrical stimulation (FES) on balance and gait function
in patients with stroke. [Subjects] Subjects were randomly allocated to a BCI-FES group
(n=5) and a FES group (n=5). [Methods] The BCI-FES group received ankle dorsiflexion
training with FES according to a BCI-based program for 30 minutes per day for 5 days. The
FES group received ankle dorsiflexion training with FES for the same duration. [Results]
Following the intervention, the BCI-FES group showed significant differences in Timed Up
and Go test value, cadence, and step length on the affected side. The FES group showed no
significant differences after the intervention. However, there were no significant
differences between the 2 groups after the intervention. [Conclusion] The results of this
study suggest that BCI-based FES training is a more effective exercise for balance and
gait function than FES training alone in patients with stroke.Key words: Brain-computer interface, Functional electrical stimulation, Gait 相似文献
