Abstract
Stroke rehabilitation, which demands consistent, intensive, and adaptable intervention in the long term, faced significant challenges due to the COVID-19 pandemic. During this time, telerehabilitation emerged as a noteworthy complement to traditional rehabilitation services, offering the convenience of at-home care delivery and overcoming geographical and resource limitations. Self-help rehabilitation robots deliver repetitive and intensive physical assistance, thereby alleviating the labor burden. However, robots have rarely demonstrated long-term readiness for poststroke telerehabilitation services. The transition from research trials to general clinical services presents several challenges that may undermine the rehabilitative gains observed in these studies. This perspective discusses the technological readiness of personal use robots in the context of telerehabilitation and identifies the potential challenges for their clinical translation. The goal is to leverage technology to seamlessly integrate it into standard clinical workflows, ultimately enhancing the outcomes of stroke rehabilitation.

[PMID: 37741026 DOI: 10.1016/j.msard.2023.105008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 08/28/2023] [Accepted: 09/13/2023] [Indexed: 09/25/2023]
Abstract
BACKGROUND Rehabilitation is the mainstay of management for people with disabilities of neurological origin to maximize function and reduce disability. Access to in-patient rehabilitation is usually reserved for people after crises or those who are discharged from acute care such as in stroke or trauma. Access to people with Multiple Sclerosis (MS) differs across countries and unknown for Canada. With the progression of MS, quality of life (QOL) becomes more closely coupled with independence and hence timely access to rehabilitation is important. The objectives of this paper are (i) to characterize the disability profiles of people with MS admitted to in-patient rehabilitation in Canada; and (ii) to estimate the extent to which disability profiles differ from admission to discharge. METHODS A longitudinal study of a rehabilitation admission-to-discharge cohort of 3500 people with MS was conducting using latent class analysis on the five Functional Independence Measure (FIM) subscales for Self-care, Transfers, Locomotion, Bladder/Bowel, and Cognition. The extent to which age, sex, and calendar time was associated with latent class membership, at both admission and discharge, was estimated using ordinal logistic regression, and proportional odds model was calculated for each age and sex. RESULTS At admission five classes were identified. The two most prevalent classes included people with total or moderate dependency in all FIM subscales except cognition (n = 1205 and n = 1099). The third most common was dependent in ambulation only (n = 523), followed by dependence in ambulation with varying degree of limitation in self-care and transfers (n = 465, and n = 208). At discharge four classes were identified with the largest class comprising of people dependent in ambulation and to a lesser degree in transfers (n = 1010). The second most prevalent class was no dependency (n = 946), followed by two classes with varying dependency in all subscales but cognition (n = 678 and n = 771). CONCLUSION Overall 62.3% of admissions transitioned to a more functional class by discharge. By discharge 28% of the population was characterized by no dependencies; however, 23% remained with dependencies in all areas. Those in the most dependent classes showed the greatest probability of transitioning to a better class at discharge highlighting the importance of reserving scarce rehabilitation services to those with more disability.

Abstract
Rehabilitation robots are helpful in poststroke telerehabilitation; however, their feasibility and rehabilitation effectiveness in clinical settings have not been sufficiently investigated. A non-randomized controlled trial was conducted to investigate the feasibility of translating a telerehabilitation program assisted by a mobile wrist/hand exoneuromusculoskeleton (WH-ENMS) into routine clinical services and to compare the rehabilitative effects achieved in the hospital-service-based group (n = 12, clinic group) with the laboratory-research-based group (n = 12, lab group). Both groups showed significant improvements (p ≤ 0.05) in clinical assessments of behavioral motor functions and in muscular coordination and kinematic evaluations after the training and at the 3-month follow-up, with the lab group demonstrating better motor gains than the clinic group (p ≤ 0.05). The results indicated that the WH-ENMS-assisted tele-program was feasible and effective for upper limb rehabilitation when integrated into routine practice, and the quality of patient-operator interactions physically and remotely affected the rehabilitative outcomes.

Home-based self-help telerehabilitation of the upper limb assisted by an electromyography-driven wrist/hand exoneuromusculoskeleton after stroke. J Neuroeng Rehabil 2021; 18:137. [PMID: 34526058 PMCID: PMC8442816 DOI: 10.1186/s12984-021-00930-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 08/31/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Most stroke survivors have sustained upper limb impairment in their distal joints. An electromyography (EMG)-driven wrist/hand exoneuromusculoskeleton (WH-ENMS) was developed previously. The present study investigated the feasibility of a home-based self-help telerehabilitation program assisted by the aforementioned EMG-driven WH-ENMS and its rehabilitation effects after stroke. METHODS Persons with chronic stroke (n = 11) were recruited in a single-group trial. The training progress, including the training frequency and duration, was telemonitored. The clinical outcomes were evaluated using the Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), Motor Functional Independence Measure (FIM), and Modified Ashworth Scale (MAS). Improvement in muscle coordination was investigated in terms of the EMG activation level and the Co-contraction Index (CI) of the target muscles, including the abductor pollicis brevis (APB), flexor carpi radialis-flexor digitorum (FCR-FD), extensor carpi ulnaris-extensor digitorum (ECU-ED), biceps brachii (BIC), and triceps brachii (TRI). The movement smoothness and compensatory trunk movement were evaluated in terms of the following two kinematic parameters: number of movement units (NMUs) and maximal trunk displacement (MTD). The above evaluations were conducted before and after the training. RESULTS All of the participants completed the home-based program with an intensity of 63.0 ± 1.90 (mean ± SD) min/session and 3.73 ± 0.75 (mean ± SD) sessions/week. After the training, motor improvements in the entire upper limb were found, as indicated by the significant improvements (P < 0.05) in the FMA, ARAT, WMFT, and MAS; significant decreases (P < 0.05) in the EMG activation levels of the APB and FCR-FD; significant decreases (P < 0.05) in the CI of the ECU-ED/FCR-FD, ECU-ED/BIC, FCR-FD/APB, FCR-FD/BIC, FCR-FD/TRI, APB/BIC and BIC/TRI muscle pairs; and significant reductions (P < 0.05) in the NMUs and MTD. CONCLUSIONS The results suggested that the home-based self-help telerehabilitation program assisted by EMG-driven WH-ENMS is feasible and effective for improving the motor function of the paretic upper limb after stroke.

Abstract
Background: Surface electromyography (sEMG) based robot-assisted rehabilitation systems have been adopted for chronic stroke survivors to regain upper limb motor function. However, the evaluation of rehabilitation effects during robot-assisted intervention relies on traditional manual assessments. This study aimed to develop a novel sEMG data-driven model for automated assessment. Method: A data-driven model based on a three-layer backpropagation neural network (BPNN) was constructed to map sEMG data to two widely used clinical scales, i.e., the Fugl-Meyer Assessment (FMA) and the Modified Ashworth Scale (MAS). Twenty-nine stroke participants were recruited in a 20-session sEMG-driven robot-assisted upper limb rehabilitation, which consisted of hand reaching and withdrawing tasks. The sEMG signals from four muscles in the paretic upper limbs, i.e., biceps brachii (BIC), triceps brachii (TRI), flexor digitorum (FD), and extensor digitorum (ED), were recorded before and after the intervention. Meanwhile, the corresponding clinical scales of FMA and MAS were measured manually by a blinded assessor. The sEMG features including Mean Absolute Value (MAV), Zero Crossing (ZC), Slope Sign Change (SSC), Root Mean Square (RMS), and Wavelength (WL) were adopted as the inputs to the data-driven model. The mapped clinical scores from the data-driven model were compared with the manual scores by Pearson correlation. Results: The BPNN, with 15 nodes in the hidden layer and sEMG features, i.e., MAV, ZC, SSC, and RMS, as the inputs to the model, was established to achieve the best mapping performance with significant correlations (r > 0.9, P < 0.001), according to the FMA. Significant correlations were also obtained between the mapped and manual FMA subscores, i.e., FMA-wrist/hand and FMA-shoulder/elbow, before and after the intervention (r > 0.9, P < 0.001). Significant correlations (P < 0.001) between the mapped and manual scores of MASs were achieved, with the correlation coefficients r = 0.91 at the fingers, 0.88 at the wrist, and 0.91 at the elbow after the intervention. Conclusion: An sEMG data-driven BPNN model was successfully developed. It could evaluate upper limb motor functions in chronic stroke and have potential application in automated assessment in post-stroke rehabilitation, once validated with large sample sizes.

Abstract
This article presents a novel electromyography (EMG)-driven exoneuromusculoskeleton that integrates the neuromuscular electrical stimulation (NMES), soft pneumatic muscle, and exoskeleton techniques, for self-help upper limb training after stroke. The developed system can assist the elbow, wrist, and fingers to perform sequential arm reaching and withdrawing tasks under voluntary effort control through EMG, with a lightweight, compact, and low-power requirement design. The pressure/torque transmission properties of the designed musculoskeletons were quantified, and the assistive capability of the developed system was evaluated on patients with chronic stroke (n = 10). The designed musculoskeletons exerted sufficient mechanical torque to support joint extension for stroke survivors. Compared with the limb performance when no assistance was provided, the limb performance (measured as the range of motion in joint extension) significantly improved when mechanical torque and NMES were provided (p < 0.05). A pilot trial was conducted on patients with chronic stroke (n = 15) to investigate the feasibility of using the developed system in self-help training and the rehabilitation effects of the system. All the participants completed the self-help device-assisted training with minimal professional assistance. After a 20-session training, significant improvements were noted in the voluntary motor function and release of muscle spasticity at the elbow, wrist, and fingers, as indicated by the clinical scores (p < 0.05). The EMG parameters (p < 0.05) indicated that the muscular coordination of the entire upper limb improved significantly after training. The results suggested that the developed system can effectively support self-help upper limb rehabilitation after stroke. ClinicalTrials.gov Register Number NCT03752775.

Functional Recovery Rate: A Feasible Method for Evaluating and Comparing Rehabilitation Outcomes Between Skilled Nursing Facilities. J Am Med Dir Assoc 2020; 22:1633-1639.e3.

Abstract
OBJECTIVES The recovery of patients' physical function and the rate at which this occurs are important parameters for evaluating value in post-acute care (PAC). However, no metrics are presently used to compare skilled nursing facilities (SNFs) based on the functional recovery rates (FRRs) for patients in their care. The objectives of this study were to examine whether the average FRR differed significantly among SNFs and to compare the FRR to other measures currently used to assess care quality in SNFs. DESIGN Retrospective observational study. SETTING AND PARTICIPANTS 3913 patients discharged from hospitals in one health system to one of 10 partner SNFs between January 2017 and September 2019. METHODS The FRR-the difference in Activity Measure for Post-Acute Care 6-Clicks basic mobility score from SNF admission to discharge relative to the SNF length of stay (in days)-was the primary outcome. Secondary outcomes included metrics from the SNF Quality Reporting Program (functional recovery alone, discharge to the community, and 30-day hospital readmission). Differences in patients' outcomes between SNFs were tested using multiple regression in order to adjust for patient characteristics. RESULTS Across the 10 SNFs, the highest adjusted mean FRR was 0.70 [95% confidence interval (CI): 0.55, 0.90] and the lowest was 0.39 (95% CI: 0.33, 0.46) points per day. Two SNFs had an adjusted mean FRR statistically higher, and 2 had an FRR statistically lower, than the sample mean (0.50, 95% CI: 0.48-0.52). SNF rankings varied by metric. CONCLUSIONS AND IMPLICATIONS Individual SNFs vary in their mean FRR for patients making it a potentially useful measure of value for comparing SNFs. Standardized measurement and reporting of FRR could be beneficial to patients and their families as they consider specific SNFs for necessary post-acute rehabilitation and to hospital systems seeking to identify high-value PAC providers with whom to partner in collaborative care models.

Abstract
Background Different mechanical supporting strategies to the joints in the upper extremity (UE) may lead to varied rehabilitative effects after stroke. This study compared the rehabilitation effectiveness achieved by electromyography (EMG)-driven neuromuscular electrical stimulation (NMES)-robotic systems when supporting to the distal fingers and to the proximal (wrist-elbow) joints. Methods Thirty subjects with chronic stroke were randomly assigned to receive motor trainings with NMES-robotic support to the finger joints (hand group, n = 15) and with support to the wrist-elbow joints (sleeve group, n = 15). The training effects were evaluated by the clinical scores of Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), and Modified Ashworth Scale (MAS) before and after the trainings, as well as 3 months later. The cross-session EMG monitoring of EMG activation level and co-contraction index (CI) were also applied to investigate the recovery progress of muscle activations and muscle coordination patterns through the training sessions. Results Significant improvements (P < 0.05) in FMA full score, FMA shoulder/elbow (FMA-SE) and ARAT scores were found in both groups, whereas significant improvements (P < 0.05) in FMA wrist/hand (FMA-WH) and MAS scores were only observed in the hand group. Significant decrease of EMG activation levels (P < 0.05) of UE flexors was observed in both groups. Significant decrease in CI values (P < 0.05) was observed in both groups in the muscle pairs of biceps brachii and triceps brachii (BIC&TRI) and the wrist-finger flexors (flexor carpi radialis-flexor digitorum) and TRI (FCR-FD&TRI). The EMG activation levels and CIs of the hand group exhibited faster reductions across the training sessions than the sleeve group (P < 0.05). Conclusions Robotic supports to either the distal fingers or the proximal elbow-wrist could achieve motor improvements in UE. The robotic support directly to the distal fingers was more effective than to the proximal parts in improving finger motor functions and in releasing muscle spasticity in the whole UE.

Abstract
Background Impaired hand dexterity is a major disability of the upper limb after stroke. An electromyography (EMG)-driven neuromuscular electrical stimulation (NMES) robotic hand was designed previously, whereas its rehabilitation effects were not investigated. Objectives This study aims to investigate the rehabilitation effectiveness of the EMG-driven NMES-robotic hand-assisted upper-limb training on persons with chronic stroke. Method A clinical trial with single-group design was conducted on chronic stroke participants (n = 15) who received 20 sessions of EMG-driven NMES-robotic hand-assisted upper-limb training. The training effects were evaluated by pretraining, posttraining, and 3-month follow-up assessments with the clinical scores of the Fugl-Meyer Assessment (FMA), the Action Research Arm Test (ARAT), the Wolf Motor Function Test, the Motor Functional Independence Measure, and the Modified Ashworth Scale (MAS). Improvements in the muscle coordination across the sessions were investigated by EMG parameters, including EMG activation level and Co-contraction Indexes (CIs) of the target muscles in the upper limb. Results Significant improvements in the FMA shoulder/elbow and wrist/hand scores (P < 0.05), the ARAT (P < 0.05), and in the MAS (P < 0.05) were observed after the training and sustained 3 months later. The EMG parameters indicated a significant decrease of the muscle activation level in flexor digitorum (FD) and biceps brachii (P < 0.05), as well as a significant reduction of CIs in the muscle pairs of FD and triceps brachii and biceps brachii and triceps brachii (P < 0.05). Conclusion The upper-limb training integrated with the assistance from the EMG-driven NMES-robotic hand is effective for the improvements of the voluntary motor functions and the muscle coordination in the proximal and distal joints. Furthermore, the motor improvement after the training could be maintained till 3 months later. Trial registration ClinicalTrials.gov. NCT02117089; date of registration: April 10, 2014.

Abstract
BACKGROUND Recovery after stroke is long-term and demanding. Optimising community-residing stroke survivors' capability to self-manage their health is integral. Recent systematic reviews have shown that stroke self-management programmes were associated with significant improvement in stroke survivors' health-related quality of life and self-efficacy. However some programmes were not designed with an underpinning theoretical framework. The aim of this study is to compare the effectiveness of a nurse-led stroke self-management programme with usual care on recovery of community-residing stroke survivors. METHODS/DESIGN A single-blinded, two-arm, randomised controlled trial will be conducted. Patients with a history of first or recurrent ischaemic or haemorrhagic stroke who will be discharged to home settings will be recruited from acute stroke units of three acute public hospitals in Hong Kong. The estimated sample size is 160 (80 participants per group). Eligible participants will be randomised to receive either usual care or a 4-week nurse-led community-based self-management programme plus usual care after discharge. The programme, underpinned by Bandura's constructs of self-efficacy and outcome expectation, includes one individual home visit, two community-based group sessions, and three follow-up phone calls. Primary outcomes include stroke survivors' self-efficacy and outcome expectation of performing self-management behaviours. Secondary outcomes include health-related quality of life, satisfaction with performance of self-management behaviours, depressive symptoms, and community reintegration. Participants will be assessed at baseline and at 8 weeks after randomisation. Generalised estimating equations will be performed to evaluate the significance of changes in outcomes over time by treatment condition. Research ethics approvals were obtained. DISCUSSION It is expected that stroke survivors receiving the stroke self-management programme will have improved self-efficacy, outcome expectation, and performance of stroke self-management behaviours. Enhanced quality of life and level of community reintegration, and decreased depressive symptoms are also expected. The study results will provide valuable evidence to inform future identification and evaluation of best approach to deliver stroke self-management programmes to enhance community-residing stroke survivors' recovery.

Abstract
INTRODUCTION Health locus of control is a measure of an individual's beliefs in factors that are thought to determine health experiences. Scores are generated and form a graduated linear scale from external to internal control, with respect to their views on health causality. Health locus of control has been considered to be a relatively stable entity. However, it is not clear if this status changes in the advent of serious health challenges, such as coronary artery bypass graft surgery. The aim of this study is to explore the variability of health locus of control and its association with postoperative health in this context. METHODS In a longitudinal cohort study of patients undergoing coronary artery bypass graft surgery, a purposive sample ( n=215) were recruited from the waiting list and followed up postoperatively, at approximately one year and seven years later. RESULTS Patients undergoing coronary artery bypass graft surgery demonstrated marked fluctuations in health locus of control in their peri-operative and rehabilitative phases. Mean health locus of control became more external (often associated with poorer outcomes) peri-operatively, and more internal (generally associated with better health outcomes) in the rehabilitative period. CONCLUSIONS Health locus of control scores were shown to be changeable during a major health care intervention, with possible consequences for patient outcomes and care needs. The significant health belief upheaval demonstrated in this cohort should be considered in assessing patients preoperatively, and managed as part of the patients' clinical journey by both acute and rehabilitation staff. It is likely to have particular importance in individualised assessment and management of future prevention advice for patients.

Abstract
Background The importance of long term rehabilitation for people with stroke is increasingly evident, yet it is not known whether such services can be materialised in countries with limited community resources. In this study, we explored the perception of rehabilitation professionals and people with stroke towards long term stroke rehabilitation services and potential approaches to enable provision of these services. Views from providers and users are important in ensuring whatever strategies developed for long term stroke rehabilitations are feasible and acceptable. Methods Focus group discussions were conducted involving 15 rehabilitation professionals and eight long term stroke survivors. All recorded conversations were transcribed verbatim and analysed using the principles of qualitative research. Results Both groups agreed that people with stroke may benefit from more rehabilitation compared to the amount of rehabilitation services presently provided. Views regarding the unavailability of long term rehabilitation services due to multi-factorial barriers were recognised. The groups also highlighted the urgent need for the establishment of community-based stroke rehabilitation centres. Family-assisted home therapy was viewed as a potential approach to continued rehabilitation for long term stroke survivors, given careful planning to overcome several family-related issues. Conclusions Barriers to the provision of long term stroke rehabilitation services are multi-factorial. Establishment of community-based stroke rehabilitation centres and training family members to conduct home-based therapy are two potential strategies to enable the continuation of rehabilitation for long term stroke survivors.

Abstract
BACKGROUND The most effective and efficient model for providing organized stroke care remains uncertain. This study aimed to compare the effect of two models in a randomized controlled trial. METHODS Patients with acute stroke were randomized on day one of admission to combined, co-located acute/rehabilitation stroke care or traditionally separated acute/rehabilitation stroke care. Outcomes measured at baseline and 90 days postdischarge included functional independence measure, length of hospital stay, and functional independence measure efficiency (change in functional independence measure score ÷ total length of hospital stay). RESULTS Among 41 patients randomized, 20 were allocated co-located acute/rehabilitation stroke care and 21 traditionally separated acute/rehabilitation stroke care. Baseline measurements showed no significant difference. There was no significant difference in functional independence measure scores between the two groups at discharge and again at 90 days postdischarge (co-located acute/rehabilitation stroke care: 103.6 ± 22.2 vs. traditionally separated acute/rehabilitation stroke care: 99.5 ± 27.7; P = 0.77 at discharge; co-located acute/rehabilitation stroke care: 109.5 ± 21.7 vs. traditionally separated acute/rehabilitation stroke care: 104.4 ± 27.9; P = 0.8875 at 90 days post-discharge). Total length of hospital stay was 5.28 days less in co-located acute/rehabilitation stroke care compared with traditionally separated acute/rehabilitation stroke care (24.15 ± 3.18 vs. 29.42 ± 4.5, P = 0.35). There was significant improvement in functional independence measure efficiency score among participants assigned to co-located acute/rehabilitation stroke care compared with traditionally separated acute/rehabilitation stroke care (co-located acute/rehabilitation stroke care: median 1.60, interquartile range: 0.87-2.81; traditionally separated acute/rehabilitation stroke care: median 0.82, interquartile range: 0.27-1.57, P = 0.0393). Linear regression analysis revealed a high inverse correlation (R(2) = 0.89) between functional independence measure efficiency and time spent in the acute stroke unit. CONCLUSION This proof-of-concept study has shown that co-located acute/rehabilitation stroke care was just as effective as traditionally separated acute/rehabilitation stroke care as reflected in functional independence measure scores, but significantly more efficient as shown in greater functional independence measure efficiency. Co-located acute/rehabilitation stroke care has potential for significantly improved hospital bed utilization with no patient disadvantage.

Abstract
OBJECTIVES To (1) identify all available rehabilitation impact indices (RIIs) based on their mathematical formula, (2) assess the evidence for independent predictors of each RII and (3) propose a nomenclature system to harmonise the names of RIIs. DESIGN Systematic review. DATA SOURCES PubMed and references in primary articles. STUDY SELECTION First, we identified all available RII through preliminary literature review. Then, various names of the same formula were used to identify studies, limited to articles in English and up to 31 December 2011, including case-control and cohort studies, and controlled interventional trials where RIIs were outcome variable and matching or multivariate analysis was performed. RESULTS The five RIIs identified were (1) absolute functional gain (AFG)/absolute efficacy/total gain, (2) rehabilitation effectiveness (REs)/Montebello Rehabilitation Factor Score (MRFS)/relative functional gain (RFG), (3) rehabilitation efficiency (REy)/length of stay-efficiency (LOS-EFF)/efficiency, (4) relative functional efficiency (RFE)/MRFS efficiency and (5) revised MRFS (MRFS-R). REy/LOS-EFF/efficiency had the most number of supporting studies, followed by REs and AFG. Although evidence for different predictors of RIIs varied according to the RII and study population, there is good evidence that older age, lower prerehabilitation functional status and cognitive impairment are predictive of poorer AFG, REs and REy. CONCLUSIONS 5 RIIs have been developed in the past two decades as composite rehabilitation outcome measures controlling premorbid and prerehabilitation functional status, rate of functional improvement, each with varying levels of evidence for its predictors. To address the issue of multiple names for the same RII, a new nomenclature system is proposed to harmonise the names based on common mathematical formula and a first-named basis.

Abstract
OBJECTIVE To study the functional outcome of stroke rehabilitation from 2 units that are similar in most aspects except for location: freestanding rehabilitation units (FSRU) versus acute care hospital (acute hospital rehabilitation unit [AHRU]). DESIGN An observational retrospective cohort study. SETTING Rehabilitation units in university-affiliated hospitals in Australia. METHODS Five-year data on functional outcomes of stroke rehabilitation and rehabilitation process measures from an FSRU were compared with data from the subsequent 5 years after the same unit was relocated to an AHRU. MAIN OUTCOME MEASUREMENTS Time from stroke onset to rehabilitation assessment, time to transfer to rehabilitation, length of stay (LOS), Functional Independence Measure (FIM) score, Motor Assessment Scale (MAS) score, transfer back to acute care, walking velocity, and discharge destination. RESULTS Data on 357 patients from an FSRU and 372 patients from an AHRU who completed the rehabilitation program are presented. Baseline characteristics, such as age, gender, stroke location, stroke type, and risk factors, were similar in the 2 groups. There was no difference in outcomes such as FIM score, MAS score, walking velocity, or discharge destination. On regression analysis, the patients in an FSRU had a longer LOS (37.6 versus 35.9 days) and were more likely to be transferred to acute care than from an AHRU (12.4% versus 5.4%). The episode LOS (total LOS in acute and rehabilitation units) was nearly identical in the 2 settings at 52.6 days (15 in acute care + 37.6 days in an FSRU and 16.7 in acute care + 35.9 days in an AHRU). CONCLUSIONS Stroke rehabilitation effectiveness is not related to the proximity of a rehabilitation facility to acute medical services. However, the increased need for the transfer of patients with medical complications from FSRU to acute care, longer LOS in an FSRU, and greater difficulty in obtaining consultations from other medical specialties persuade us to recommend a unit co-located with acute care services instead of an FSRU.
