RESUMEN

OBJECTIVE: To examine the cardiorespiratory effects of a forced-rate aerobic exercise (FE) intervention among individuals with chronic stroke compared with an upper extremity repetitive task practice (UE RTP) control group. DESIGN: Secondary analysis of data from a randomized controlled trial. SETTING: Research laboratory. PARTICIPANTS: Individuals with chronic stroke (N=60). INTERVENTIONS: Participants completed 24 sessions of FE followed by RTP (FE+RTP, N=30) or time matched RTP alone (N=30). The FE+RTP group was prescribed exercise at 60%-80% of heart rate reserve on a motorized stationary cycle ergometer for 45 minutes followed by 45 minutes of RTP. The control group completed 90 minutes of RTP. MAIN OUTCOME MEASURES: Metabolic exercise stress tests on a cycle ergometer were conducted at baseline and post-intervention. Outcomes included peak oxygen consumption (peak V̇o2) and anaerobic threshold (AT). RESULTS: Fifty participants completed the study intervention and pre/post stress tests. The FE+RTP group demonstrated significantly greater improvements in peak V̇o2 from 16.4±5.7 to 18.3±6.4 mL/min/kg compared with the RTP group (17.0±5.6 to 17.2±5.6 mL/min/kg, P=.020) and significantly greater improvements in AT from 10.3±2.8 to 11.5±3.6 mL/min/kg compared with the RTP group (10.8±3.9 to 10.4±3.2 mL/min/kg, P=.020). In analyzing predictors of post-intervention peak V̇o2, the multivariable linear regression model did not reveal a significant effect of age, sex, body mass index, or beta blocker usage. Similarly, bivariate linear regression models for the FE group only did not find any exercise variables (aerobic intensity, power, or cycling cadence) to be significant predictors of peak V̇o2. CONCLUSIONS: While the aerobic exercise intervention was integrated into rehabilitation to improve UE motor recovery, it was also effective in eliciting significant and meaningful improvements in cardiorespiratory fitness. This novel rehabilitation model may be an effective approach to improve motor and cardiorespiratory function in persons recovering from stroke.

RESUMEN

OBJECTIVE: The aim of this study was 1) to describe the rate of intrathecal baclofen (ITB)-associated complications at a large tertiary center, and 2) to evaluate the impact of patient-related factors on the likelihood of developing such complications. METHODS: A retrospective single-center study was carried out. A total of 301 eligible patients were included in the analysis. Univariate regression models were used to evaluate the impact of age, sex, diagnosis, ambulation status, modified Ashworth scale score, body mass index, diabetes status, and pain level on the likelihood of developing a device-related infection, pump malfunction, catheter malfunction, and other clinically significant complications. RESULTS: Overall, 27% of patients experienced an ITB-related complication. The most common complications included infection (6%, 18/301), pump malfunction (7.3%, 22/301), and catheter malfunction (14%, 42/301). The univariate analyses revealed that the patient's ambulatory status had a significant impact on the likelihood of developing a catheter-related malfunction. Furthermore, a trend toward significance was identified between patients' preoperative body mass index and device-related infection. Finally, the risk of suffering any ITB-related complications was statistically correlated with the number of years that had passed since the initial pump implantation. CONCLUSIONS: The authors' analysis reveals a previously underrecognized association between ambulatory status at the time of ITB pump implantation and the incidence of catheter-related complications, and confirms the impact of time since surgery on the risk of developing any ITB-related complication. The patient's age, sex, diagnosis, diabetes status, or pain level at baseline were not associated with the risk of complications. Collectively, these insights contribute novel information to the existing literature, providing practical value for physicians in guiding patient selection for ITB therapy.

RESUMEN

BACKGROUND: Physical therapists (PTs) are consulted to address functional deficits during hospitalization, but the effect of PT visit frequency on patients' outcomes is not clear. OBJECTIVE: The objective of this study was to examine whether PT visit frequency is independently associated with functional improvement, discharge home, and both outcomes combined. RESEARCH DESIGN: This was a retrospective cohort study. SUBJECTS: Patients discharged from hospitals in 1 health system between 2017 and 2020, stratified by diagnostic subgroup: cardiothoracic and vascular, general medical/surgical, neurological, oncology, and orthopedic. MEASURES: PT visit frequency was categorized as ≤2, >2-4, >4-7, >7 visits/week. Functional improvement was defined as ≥5-point improvement in Activity Measure for Post-Acute Care mobility score. Other outcomes were discharge home and both outcomes combined. RESULTS: There were 243,779 patients included. Proportions within frequency categories ranged from 11.0% (>7 visits/wk) to 40.5% (≤2 visits/wk) and varied by subgroup. In the full sample, 36% of patients improved function, 64% were discharged home, and 27% achieved both outcomes. In adjusted analyses, relative to ≤2 visits/week, the adjusted relative risk (aRR) for functional improvement increased incrementally with higher frequency (aRR=1.20, 95% confidence interval: 1.14-1.26 for >2-4 visits to aRR=1.78, 95% confidence interval: 1.55-2.03 for >7 visits). For all patients and within subgroups, the higher frequency was also associated with a greater likelihood of discharging home and achieving both outcomes. CONCLUSIONS: More frequent PT visits during hospitalization may facilitate functional improvement and discharge home. Most patients, however, receive infrequent visits. Further research is needed to determine the optimal delivery of PT services to meet individual patient needs.

RESUMEN

STUDY DESIGN: A multisite, randomized, controlled, double-blinded phase I/II clinical trial. OBJECTIVE: The purpose of this clinical trial is to evaluate the safety, feasibility and efficacy of pairing noninvasive transcranial direct current stimulation (tDCS) with rehabilitation to promote paretic upper extremity recovery and functional independence in persons living with chronic cervical spinal cord injury (SCI). SETTING: Four-site trial conducted across Cleveland Clinic, Louis Stokes Veterans Affairs Medical Center of Cleveland and MetroHealth Rehabilitation Rehabilitation Institute of Ohio, and Kessler Foundation of New Jersey. METHODS: Forty-four adults (age ≥18 years) with tetraplegia following cervical SCI that occurred ≥1-year ago will participate. Participants will be randomly assigned to receive anodal tDCS or sham tDCS given in combination with upper extremity rehabilitation for 15 sessions each over 3-5 weeks. Assessments will be made twice at baseline separated by at least a 3-week interval, once at end-of-intervention, and once at 3-month follow-up. PRIMARY OUTCOME MEASURE(S): Primary outcome measure is upper extremity motor impairment assessed using the Graded Redefined Assessment of Strength, Sensibility and Prehension (GRASSP) scale. Functional abilities will be assessed using Capabilities of Upper Extremity-Test (CUE-T), while functional independence and participation restrictions will be evaluated using the self-care domain of Spinal Cord Independent Measure (SCIM), and Canadian Occupational Performance Measure (COPM). SECONDARY OUTCOME MEASURES: Treatment-associated change in corticospinal excitability and output will also be studied using transcranial magnetic stimulation (TMS) and safety (reports of adverse events) and feasibility (attrition, adherence etc.) will also be evaluated. TRIAL REGISTRATION: ClincalTrials.gov identifier NCT03892746. This clinical trial is being performed at four sites within the United States: Cleveland Clinic (lead site), Louis Stokes Cleveland Veterans Affairs Medical Center (VAMC) and MetroHealth Rehabilitation Institute in Ohio, and Kessler Foundation in New Jersey. The U.S. Army Medical Research Acquisition Activity, 820 Chandler Street, Fort Detrick MD 21702-5014 is the awarding and administering acquisition office.

RESUMEN

BACKGROUND: Intrathecal baclofen (ITB) is traditionally reserved for non-ambulatory patients. OBJECTIVE: To investigate outcomes of ITB in ambulatory multiple sclerosis (MS) patients. METHODS: Changes in outcome measures were estimated by a mixed effect model, while the complication rate was calculated using a logistic regression. Predictors of non-ambulatory status were identified by Cox model. RESULTS: In all, 256 patients received an ITB test injection and 170 underwent ITB surgery. Aggregate Modified Ashworth Scale (MAS) scores for the ambulatory ITB cohort decreased from 13.5 ± 6.96 to 4.54 ± 4.18 at 5 years (p < 0.001). There was no significant change in walking speed 1 year post ITB surgery (0.45 m/second ± 0.30 vs 0.38 m/second ± 0.39, p = 0.80) with 77.8% of patients remaining ambulatory which decreased to 41.7% at year 5. Longer MS disease duration (hazard ratio (HR): 1.04; 95% confidence interval (CI): 1.01-1.07; p = 0.018) and lower hip flexor strength (HR: 0.40; 95% CI: 0.27-0.57; p < 0.001) predicted non-ambulatory status after surgery. Complications were more likely in the ambulatory cohort (odds ratio (OR): 3.30, 95% CI: 2.17-5.02; p = 0.017). CONCLUSION: ITB is effective for ambulatory MS patients without compromising short-term walking speed, although a higher complication rate was observed in this cohort.

RESUMEN

Transcranial magnetic stimulation (TMS) is used to investigate corticomotor neurophysiology associated with functional recovery in individuals with spinal cord injury (SCI). There is insufficient evidence about test-retest measurement properties of TMS in SCI. Therefore, we investigated test-retest agreement and reliability of TMS metrics representing corticomotor excitability, output, gain, map (representation), and inhibition in individuals with cervical SCI. We collected TMS metrics from biceps and triceps muscles because of the relevance of this proximal muscle pair to the cervical SCI population. Twelve individuals with chronic C3-C6 SCI participated in two TMS sessions separated by ≥ 2 weeks. Measurement agreement was evaluated using t tests, Bland-Altman limits of agreement and relative standard error of measurement (SEM%), while reliability was investigated using intra-class correlation coefficient (ICC) and concordance correlation coefficient (CCC). We calculated the smallest detectable change for all TMS metrics. All TMS metrics except antero-posterior map coordinates and corticomotor inhibition were in agreement upon repeated measurement though limits of agreement were generally large. Measures of corticomotor excitability, output and medio-lateral map coordinates had superior agreement (SEM% < 10). Metrics representing corticomotor excitability, output, and inhibition had good-to-excellent reliability (ICC/CCC > 0.75). The smallest detectable change for TMS metrics was generally high for a single individual, but this value reduced substantially with increase in sample size. We recommend use of corticomotor excitability and recruitment curve area owing to their superior measurement properties. A modest group size (20 or above) yields more stable measurements, which may favor use of TMS metrics in group level modulation after SCI.

RESUMEN

OBJECTIVES: To determine the efficacy of high-intensity cycling to improve walking capacity in individuals with chronic stroke, identify variables that predict improvement in walking capacity, and quantify the relationship between the 6-minute walk test (6MWT) and cardiopulmonary exercise (CPX) test variables. DESIGN: Secondary analysis of data from 2 randomized controlled trials. SETTING: Research laboratory. PARTICIPANTS: Individuals with chronic stroke (N=43). INTERVENTIONS: Participants were randomized to 1 of the following time-matched interventions, occurring 3 times per week for 8 weeks: (1) forced aerobic exercise and upper extremity repetitive task practice (FE+RTP [n=16]), (2) voluntary aerobic exercise and upper extremity repetitive task practice (VE+RTP [n=14]), or (3) a non-aerobic control group (n=13). MAIN OUTCOME MEASURE: Change in walking capacity as measured by the 6MWT from baseline to the end of treatment (EOT). RESULTS: Significant increases were observed in distance traveled during the 6MWT at the EOT compared with baseline in the FE+RTP (P<.001) and VE+RTP (P<.001) groups, but not in the control group (P=.21). Among aerobic exercise participants, a multivariate regression analysis revealed that cycling cadence, power output, and baseline 6MWT distance were significant predictors of change in walking capacity. CONCLUSIONS: An 8-week aerobic cycling intervention prescribed at 60% to 80% of heart rate reserve and moderate to high cadence and resistance led to significant improvements in walking capacity in our cohort of individuals with chronic stroke. Individuals with low baseline walking capacity levels may benefit most from aerobic cycling to improve over ground locomotion. Although the 6MWT did not elicit a cardiorespiratory response comparable to the maximal exertion CPX test, the 6MWT can be considered a valid and clinically relevant submaximal test of cardiorespiratory function in individuals with chronic stroke.

RESUMEN

BACKGROUND: People with multiple sclerosis (MS) often experience fatigue, which is aggravated by inactivity. Identifying mediators of changes in physical activity (PA) and fatigue self-management (FSM) behaviors could optimize future interventions that reduce the impact of MS fatigue. PURPOSE TO: examine the effects of telephone-delivered interventions on Social Cognitive Theory constructs and test whether these constructs mediated secondary outcomes of PA and FSM behaviors. METHODS: Participants with MS (n = 208; Mean age = 52.1; Female = 84.6%) were randomized into contact-control intervention (CC), PA-only intervention, and PA+FSM intervention. Step count (Actigraphy) and FSM behaviors as well as self-efficacy, outcome expectations, and goal setting for PA and FSM were measured at baseline, post-test (12 weeks), and follow-up (24 weeks). Path analyses using bias-corrected bootstrapped 95% confidence intervals (CI) determined whether constructs at post-test mediated behaviors at follow-up when adjusting for baseline measures. RESULTS: Path analysis indicated that PA-only (ß = 0.50, p < .001) and PA+FSM interventions (ß = 0.42, p < .010) had an effect on goal setting for PA, and that PA + FSM intervention had an effect on self-efficacy for FSM (ß = 0.48, p = .011) and outcome expectations for FSM (ß = 0.42, p = .029). Goal setting for PA at post-test mediated the effects of PA-only (ß = 159.45, CI = 5.399, 371.996) and PA + FSM interventions (ß = 133.17, CI = 3.104, 355.349) on step count at follow-up. Outcome expectations for FSM at post-test mediated the effects of PA + FSM intervention on FSM behaviors at follow-up (ß = 0.02, CI = 0.001, 0.058). CONCLUSIONS: Goal setting for PA and outcome expectations for FSM may be important constructs to target in telephone-delivered interventions designed to reduce the impact of MS fatigue. TRIAL REGISTRATION: Clinicaltrials.gov (NCT01572714).

RESUMEN

OBJECTIVE: To compare the effectiveness of telephone-delivered interventions on fatigue, physical activity, and quality of life outcomes in adults with multiple sclerosis (MS). DESIGN: A single-blinded, randomized controlled trial. Participants were randomized to contact-control intervention (CC), physical activity-only intervention (PA-only), and physical activity plus fatigue self-management intervention (FM+). Outcomes were measured at baseline (2wk prerandomization), posttest (14wk postrandomization), and follow-up (26wk postrandomization). SETTING: Telephone-delivered in Midwest and Northeast regions of the United States. PARTICIPANTS: Inactive adults with MS (N=208) and moderate-to-severe fatigue. INTERVENTIONS: Three or 6 group teleconferences followed by 4 individually tailored phone calls delivered during 12 weeks. An occupational therapist and research assistant delivered the teleconferences and tailored phone calls, respectively. MAIN OUTCOME MEASURES: Primary outcomes were self-report fatigue and physical activity measured with the Fatigue Impact Scale and Godin Leisure-Time Exercise Questionnaire, respectively. Secondary outcomes included quality of life measured with the Multiple Sclerosis Impact Scale and moderate-to-vigorous exercise and step count measured with an accelerometer. RESULTS: Linear mixed effects models showed FM+ significantly improved self-reported fatigue (ß=-11.08; P=.03) and physical activity (ß=0.54; P=.01) compared with CC at posttest. However, FM+ had nonsignificant differences compared with PA-only on self-report fatigue (ß=-1.08, P=.84) and physical activity (ß=0.09; P=.68) at posttest. PA-only had significant improvements compared with CC on moderate-to-vigorous exercise (ß=0.38; P=.02) at posttest and step count at posttest (ß=1.30; P<.01) and follow-up (ß=1.31; P=.01) measured with an accelerometer. FM+ and PA-only had nonsignificant differences compared with CC on quality of life. CONCLUSIONS: Group teleconferences followed by tailored phone calls have a small yet statistically significant effect in promoting physical activity and reducing fatigue impact in people with MS.

RESUMEN

OBJECTIVES: Stiff-person syndrome (SPS) is associated with axial rigidity superimposed on sustained muscle spasms. These symptoms commonly interfere with the performance of activities of daily living including ambulation. This retrospective case series evaluates the outcomes of screening tests and chronic infusion of intrathecal baclofen (ITB) in patients diagnosed with SPS treated in our spasticity clinic. MATERIALS AND METHODS: Patients were identified from an institutional review board-approved clinical registry of ITB therapy. Data from clinical encounters were extracted from the registry and from the patients' electronic medical record. All patients with medically refractory spasticity related to SPS screened with an ITB injection were included. In addition to pertinent demographic and clinical information, data from validated outcome measures routinely used in the clinic were collected: pain Numeric Rating Scale, Spasm Frequency Scale, lower extremity Modified Ashworth Scale (MAS), and Timed 25 Foot Walk. Outcomes data for chronic ITB infusion were assessed at early (<6 months) and late follow-up (6-12 months) visits after surgery. RESULTS: Nine patients were included, and seven received chronic ITB infusion. MAS scores were improved at early and late follow-up, and five patients experienced a reduction in pain scores. Walking performance remained stable in previously ambulatory patients. Four patients experienced complications related to ITB implantation, which resolved with medical or surgical treatment. CONCLUSION: Consistent with other case series, our results suggest that ITB is an effective therapy for medically intractable spasticity due to SPS, and symptom reduction can be achieved without compromising ambulation.

RESUMEN

BACKGROUND: Cognitive dysfunction is common in multiple sclerosis (MS) patients and has important consequences for daily activities, yet, unlike motor function, is not routinely assessed in the clinic setting. We developed the Processing Speed Test (PST), a self-administered iPad®-based tool to measure MS-related deficits in processing speed. OBJECTIVE: To determine whether the PST is valid for screening cognitive dysfunction by comparing it to the paper-and-pencil Symbol Digit Modalities Test (SDMT). METHODS: We assessed PST test-retest reliability, sensitivity of PST and SDMT in discriminating MS patients from healthy controls (HC), convergent validity between PST and SDMT, correlations between T2 lesion load and PST and SDMT, and PST performance with and without technician present during administration. RESULTS: PST had excellent test-retest reliability, was highly correlated with SDMT, was slightly more sensitive than SDMT in discriminating MS from HC groups, and correlated better with cerebral T2 lesion load than did SDMT. Finally, PST performance was no different with or without a technician in the testing environment. CONCLUSION: PST has advantages over SDMT because of its efficient administration, scoring, and potential for medical record or research database integration. PST is a practical tool for routine screening of processing speed deficits in the MS clinic.

RESUMEN

BACKGROUND: Multiple sclerosis (MS) is a chronic, progressive, and disabling disease of the central nervous system with dramatic variations in the combination and severity of symptoms it can produce. The lack of reliable disease-specific health-related quality of life (HRQL) measures for use in clinical trials prompted the development of the Neurology Quality of Life (Neuro-QOL) instrument, which includes 13 scales that assess physical, emotional, cognitive, and social domains, for use in a variety of neurological illnesses. OBJECTIVE: The objective of this research paper is to conduct an initial assessment of the reliability and validation of the Neuro-QOL short forms (SFs) in MS. METHODS: We assessed reliability, concurrent validity, known groups validity, and responsiveness between cross-sectional and longitudinal data in 161 recruited MS patients. RESULTS: Internal consistency was high for all measures (α = 0.81-0.95) and ICCs were within the acceptable range (0.76-0.91); concurrent and known groups validity were highest with the Global HRQL question. Longitudinal assessment was limited by the lack of disease progression in the group. CONCLUSIONS: The Neuro-QOL SFs demonstrate good internal consistency, test-re-test reliability, and concurrent and known groups validity in this MS population, supporting the validity of Neuro-QOL in adults with MS.

RESUMEN

BACKGROUND: In Phase 3 double-blind trials (MS-F203 and MS-F204), dalfampridine extended release tablets 10 mg twice daily (dalfampridine-ER; prolonged-release fampridine in Europe; fampridine modified or sustained release elsewhere) improved walking speed relative to placebo in patients with multiple sclerosis (MS). OBJECTIVES: Evaluation of long-term safety and efficacy of dalfampridine-ER in open-label extensions (MS-F203EXT, MS-F204EXT). METHODS: Patients received dalfampridine-ER 10 mg twice daily; and had Timed 25-Foot Walk (T25FW) assessments at 2, 14 and 26 weeks, and then every 6 months. Subjects were categorized as dalfampridine-ER responders or non-responders, based on their treatment response in the double-blind parent trials that assessed T25FW. RESULTS: We had 269 patients enter MS-F203EXT and 154 patients complete it; for a maximum exposure of 5 years. We had 214 patients enter MS-F204EXT and 146 complete it; for a maximum exposure of 3.3 years. No new safety signals emerged and dalfampridine-ER tolerability was consistent with the double-blind phase. Improvements in walking speed were lost after dalfampridine-ER was discontinued in the parent trial, but returned by the 2-week assessment after re-initiation of the drug. Throughout the extensions, mean improvement in walking speed declined, but remained improved, among the double-blind responders as compared with non-responders. CONCLUSIONS: The dalfamipridine-ER safety profile was consistent with the parent trials. Although walking speed decreased over time, dalfampridine-ER responders continued to show improved walking speed, which was sustained compared with non-responders.

RESUMEN

Botulinum toxin (BT) is a neurotoxin that paralyzes muscles by inhibiting release of acetylcholine from presynaptic vesicles at the neuromuscular junction. In people with multiple sclerosis (MS), clinical experience and research studies show that local injection of minute quantities of BT can temporarily control skeletal muscle spasticity, bladder detrusor hyperreflexia, and tremor. Specifically, BT injections have been shown to reduce muscle tone and improve passive function, and possibly improve active function, in patients with spasticity. Injection of BT into the bladder wall is a uniquely effective, safe, and durable treatment in patients with neurogenic detrusor hyperreflexia due to MS who have insufficient response or who do not tolerate oral antimuscarinic medications. This procedure has markedly reduced the need for indwelling catheters and bladder surgery. In addition, a recent study suggests BT may be effective for select patients with MS-associated upper extremity tremor. Appropriate use of BT can improve quality of life for many patients with MS.

RESUMEN

OBJECTIVE: Investigate the feasibility and potential efficacy of a customized print-based intervention to promote physical activity and symptom self-management in women with multiple sclerosis. DESIGN: A randomly allocated two-group repeated measures design, with a delayed-treatment contact group serving as the control. Participants were randomized to receive the intervention immediately (n =14) or receive it at week 12 (n =16). Outcome measures were administered at weeks 1, 12, and 24. SETTING: Community-based in metropolitan area. SUBJECTS: Thirty women with multiple sclerosis. INTERVENTION: Prescribing a home-exercise program and following up with customized pamphlets, which are matched to participants' stage of readiness to change physical activity behavior and physical activity barriers (e.g. encouraging self-management of symptoms). MAIN MEASURES: Physical Activity and Disability Survey-revised, Godin Leisure-Time Exercise Questionnaire, SF-12, Symptoms of Multiple Sclerosis Scale, and 6-minute walk test. RESULTS: Intent-to-treat analyses using mixed multivariate analysis of variance (MANOVA) were conducted on (1) physical activity levels and (2) health and function outcomes. The mixed MANOVAs for physical activity levels and health and function outcomes indicated significant improvements in the immediate group compared with the delayed group (i.e. condition by time interaction was significant, Wilks' λ = 0.59, F(2, 27) = 9.31, P = 0.001 and Wilks' λ = 0.70, F(4, 25) = 2.72, P = 0.052, respectively). The intervention had moderate to large effect sizes in improving physical activity levels (d = 0.63 to 0.89), perceptions of physical function (d = 0.63), and 6-minute walk test (d=0.86). CONCLUSION: This pilot study indicates that a customized print-based intervention shows promise in improving physical activity levels and health and function in women with multiple sclerosis.

RESUMEN

Inactivity is a prevalent problem in the population affected with multiple sclerosis (MS). Thus, there is a need to develop and test physical activity (PA) interventions that can be widely disseminated. We conducted a formative evaluation as part of a randomized controlled trial of a pamphlet-based PA intervention among 30 women with MS. Pamphlets were customized to sub-sets of participants who shared similar symptoms and barriers to PA. Mixed methods were used to examine the intervention's influence on self-efficacy, social support, processes of change and stages of change placement, as well as explore participants' perceived barriers, motivators and strategies for engaging in a PA program. Results indicated that the intervention group significantly improved stages of change placement (F = 16.64, P < 0.01) and social support (F = 4.08, P = 0.05) in comparison to the control group. Fatigue, pain and lack of time were the commonly cited barriers to engage in the PA program; whereas the pamphlets, phone calls and action planning were cited as motivators. Participants used fatigue management strategies, enlisted social support and modified their environment to routinely engage in the PA program. Strategies were identified to improve the PA intervention in future research.

RESUMEN

PURPOSE: People with multiple sclerosis (MS) may face challenges maintaining their subjective well-being, life satisfaction, happiness, and positive emotions. This scoping review's purpose was to summarize studies on these positive psychological constructs among people with MS. METHODS: Observational and interventional studies that included measures of subjective well-being, life satisfaction, happiness, or positive affect were identified. Variables associated with these constructs were classified using the International Classification of Functioning, Disability and Health (ICF). RESULTS: The review included 22 observational and 10 interventional studies. Variables were categorized into each of the ICF domains. Cognitive behavior therapy was the most common intervention, with content and dosing varying widely. CLINICAL RELEVANCE: Subjective well-being, life satisfaction, happiness, and positive affect are crucial components of community and individual health. The findings of this scoping review highlight the complex interplay between function, personal factors, and environmental conditions in influencing positive psychological constructs. Given the limited evidence, rehabilitation nurses should leverage their skills in delivering holistic care and adopt data-driven approaches to integrate positive psychological strategies into care plans. CONCLUSION: Further research is needed to measure and compare interventions aimed at improving these constructs and to examine the influence of personal and environmental factors among diverse MS populations.

RESUMEN

Background: Healthcare workers are concerned with promoting behavior changes that enhance patients' health, wellness, coping skills, and well-being and lead to improved public health. The purpose of this randomized controlled trial was to determine if participation in an 8-week arts-based program leads to improved mood, health, resilience, and well-being in individuals with chronic health conditions as compared to a wait list control group. Methods: Self-report questionnaires for well-being, mental health, physical health, overall health, social health, mood, coping, and resilience were administered at baseline, Week 8 (end of program), and Week 16 (8-week follow-up). Results: Statistically significant improvements were noted in all outcome measures for the treatment group, as well as in most areas compared to the control group. Many of the positive results at Week 8 were either maintained or further improved at Week 16. Discussion: These results suggest that arts-based programming can have a positive effect on the mood, health, resilience, and well-being of individuals with chronic health conditions. Therefore, arts-based programming should be utilized more frequently in the management of chronic conditions in community-dwelling individuals. These benefits should be further assessed in larger clinical trials.

RESUMEN

BACKGROUND: Spasticity is a common and potentially debilitating symptom of multiple sclerosis (MS) with a highly variable presentation. Understanding, quantifying, and managing MS-associated spasticity (MSS) is a challenge for research and in clinical practice. The tetrahydrocannabinol:cannabidiol oromucosal spray nabiximols has demonstrated beneficial effects in the treatment of MSS in clinical studies as well as real-world observational studies, and is approved for the treatment of MSS in 29 countries globally. Most randomized studies evaluated the efficacy of nabiximols using the change in average daily spasticity scores reported by patients using the spasticity Numeric Rating Scale as a primary endpoint. This study, RELEASE MSS1 (NCT04657666), was conducted using a prespecified primary endpoint of change in spastic muscle tone (Modified Ashworth Scale Lower Limb Muscle Tone-6 [MAS LLMT-6]) to corroborate the efficacy of nabiximols as adjunctive therapy observed with the patient-measured spasticity Numeric Rating Scale primary endpoint in the previous pivotal studies. METHODS: This was a phase 3, multicenter, randomized, double-blind, placebo-controlled, 2-treatment, 2-period, crossover trial. Because of the prevalence and functional impact of lower limb spasticity on the individual patient's overall experience of MS spasticity, the MAS LLMT-6 was derived from the clinician-rated MAS. The MAS LLMT-6 is the average transformed MAS score of 6 muscle groups (knee flexors, knee extensors, and ankle plantar flexors; all assessed bilaterally). Secondary measures included MAS LLMT-4 scores, defined as the average of the 4 individual MAS-transformed scores of knee flexors and knee extensors bilaterally. Patients had a diagnosis of MS and an untransformed MAS score of at least 2 in ≥2 of 6 LLMT-6 muscle groups despite current treatment with ≥1 of the following oral antispasticity agents: baclofen, tizanidine, or dantrolene. Eligible participants were randomly assigned to 1 of 2 treatment sequences. Each treatment sequence consisted of two treatment periods, each consisting of a 14-day dose titration phase followed by a 7-day dose maintenance phase. RESULTS: Of 68 patients enrolled, 33 were assigned to nabiximols followed by placebo and 35 were assigned to placebo followed by nabiximols. Least squares mean changes in MAS LLMT-6 scores from baseline to day 21 were -0.23 for nabiximols and -0.26 for placebo; the least squares mean treatment difference in MAS LLMT-6 scores for nabiximols versus placebo was 0.04, which was not statistically significant (P = 0.7152). Mean changes in MAS LLMT-4 scores from baseline to day 21 also were not significantly different between the nabiximols and placebo groups. Safety results in this study were consistent with the known safety profile of nabiximols in patients with MSS. CONCLUSION: Despite the established efficacy of nabiximols in MSS observed using patient-reported measures, the primary endpoint was not met in this study. The findings from this study reflect and emphasize some of the challenges in the evaluation and treatment of MS spasticity. CLINICAL TRIAL REGISTRATION NUMBER (CLINICALTRIALS.GOV): : NCT04657666.

RESUMEN

BACKGROUND: Individuals with Parkinson disease (PD) can improve their overall mobility and participation in daily activities as they engage in frequent exercise. Despite the need for individually tailored exercises, persons with PD often face barriers to accessing physical rehabilitation professionals who can provide them. Telerehabilitation (TR) may facilitate access to necessary and individually tailored rehabilitation for individuals with PD. OBJECTIVE: The purpose of this study was to assess the feasibility of TR for individuals with PD and explore clinical outcomes compared to in-person care. METHODS: This was a pilot randomized controlled trial conducted at 2 outpatient neurorehabilitation clinics with 3 study groups: clinic+TR, TR-only, and usual care (UC). TR was administered using a web-based application with a mobile app option. One-hour interventions were performed weekly for 4 weeks, in-person for the clinic+TR and UC groups and virtually for the TR-only group. Home exercises were provided on paper for the UC group and via the web-based platform for the clinic+TR and TR-only groups. Feasibility was assessed by recruitment and retention success and patient and therapist satisfaction, as rated in surveys. Clinical outcomes were explored using performance and patient-reported measures in between- and within-group analyses. RESULTS: Of 389 patients screened, 68 (17.5%) met eligibility criteria, and 20 (29.4% of those eligible) were enrolled (clinic+TR, n=6; TR-only, n=6; and UC, n=8). One patient (TR-only) was withdrawn due to a non-study-related injurious fall. Regardless of group allocation, both patients and therapists generally rated the mode of care delivery as "good" or "very good" across all constructs assessed, including overall satisfaction and safety. In the analysis of all groups, there were no differences in clinical outcomes at the discharge visit. Within-group differences (from baseline to discharge) were also generally not significant except in the UC group (faster 5-time sit-to-stand time and higher mini balance evaluation systems test balance score) and clinic+TR group (higher mini balance evaluation systems test balance score). CONCLUSIONS: High satisfaction amongst patients and clinicians regardless of group, combined with nonsignificant between-group differences in clinical outcomes, suggest that TR is feasible for individuals with PD in early-moderate stages. Future trials with a larger sample are necessary to test clinical effectiveness. As larger trials enroll patients with diverse characteristics (eg, in terms of age, disease progression, caregiver support, technology access and capacity, etc), they could begin to identify opportunities for matching patients to the optimal utilization of TR as part of the therapy episode.
