Performance of activities of daily living in multiple sclerosis

Tablet app-based dexterity training in multiple sclerosis (TAD-MS): a randomized controlled trial

PURPOSE

Mobile health applications (mHealth apps) may lead to health benefits. In recent years, the use of apps in multiple sclerosis (MS) has increased. Apps to train and improve dexterity in MS are scarce. This study investigated the effectiveness of a tablet app-based home-based training to improve dexterity in individuals with MS.

MATERIALS AND METHODS

In a randomized controlled trial, two standardized 4-week home-based interventions focussing on different aspects of dexterity and upper limb function were compared. Assessments were done at baseline, post-intervention and 12-week follow-up. The primary endpoint was the Arm Function in Multiple Sclerosis Questionnaire, a dexterity-related measure of patient-reported activities of daily living. Secondary endpoints were dexterous function, grip strength and health-related quality of life.

RESULTS

Forty-eight individuals were randomly assigned to a tablet app-based program (n = 26) or a control strengthening exercise program (n = 22). No significant differences were found for the primary endpoint (p = 0.35). Some significant differences in favour of the app-group were found in fine coordinated finger movements and strength. No significant differences were found at the 12-week follow-up for all endpoints. Adherence in both groups was above 90%.

CONCLUSIONS

App-based training was not superior compared to a control strengthening exercise program concerning the arm- and hand function from the participant's perspective. However, app-based training was found to be effective in improving specific dimensions (finger movements and strength), and can easily be applied at home. Therefore, individuals living with MS with impaired dexterity should consider app-based training.

Translation, Cross-Cultural Adaptation, and Feasibility of the NHPT-E of Manual Dexterity for the Spanish Population

The Nine-Hole Peg Test (NHPT) is considered a "gold standard" for the measurement of manual dexterity. The aim of this study was the translation and culturally adapting the original version of the NHPT.

MATERIALS AND METHODS

The adaptation was carried out following the standardized translation-retrotranslation guidelines and procedures referred to in the literature and in the International Test Commission (CIT). The final Spanish version of the NHPT (NHPT-E) was administered to 40 healthy adults. We evaluated its feasibility by means of a questionnaire elaborated according to Iraossi's checklist proposal for the pilot test process.

RESULTS

Modifications of expression in the grammatical mode of the verbs were performed, as well as the adaptation of some terms used in the three sections of the original version of the test (General Information, Installation, and Application Instructions). In the pilot study, for 95% of the participants, the NHPT-E is a comfortable test to take, and, for 100% of the evaluators, the test includes all the necessary information, with clear instructions and interpretation of the results.

CONCLUSIONS

The cross-cultural adaptation and pilot study enabled the development of a suitable and viable version of the NHPT-E for use in the Spanish population.

Assessing everyday functional activity in cognitively impaired people with multiple sclerosis: The use of Actual RealityTM

BACKGROUND

There is considerable evidence that persons with multiple sclerosis (PwMS) who experience cognitive impairments (CIs) are at risk of having significant limitations in activities of daily living (ADLs). However, ADL assessment often consists of proxies or self-report of ADLs. This study examined whether the performance of instrumental ADLs (I-ADL) is impaired in PwMS with and without CI.

METHODS

Participants included 72 PwMS and 48 matched healthy controls (HCs). PwMS were divided into MS-CI (n = 25) and MS-not-impaired (n = 47) groups based on the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) scores. All participants performed the Actual RealityTM (AR) test, measuring I-ADL using authentic websites.

RESULTS

The MS-CI performed significantly worse on AR compared with HC and MS-not-impaired. In addition, the MS-not-impaired performed significantly worse than HC on AR. AR differentiates well between PwMS with and without CI.

CONCLUSIONS

While CI in MS results in significant limitations in the performance of I-ADL, PwMS who do not show evidence of CI can have limitations in I-ADL. AR assessment is a valid and reliable tool sensitive to CI. It should be used in addition to traditional cognitive assessments to detect early functional deterioration through the course of MS.

The effect of exercise on walking economy in patients with chronic neurological conditions: A systematic review and meta-analysis

Introduction

To investigate the effect of exercise on the walking economy (WE) of patients with chronic neurological conditions (CNCs) and to determine the type of physical activity that best improves the WE of patients with CNCs.

Methods

Four electronic databases were searched until December 2022 (Web of Science, PubMed, Cochrane, and CINAHL). Studies were screened using the following inclusion criteria: 1. randomized controlled or non-randomized controlled trials; 2. exercise interventions >4 weeks in duration; 3. patients aged ≥18 years with a diagnosis of CNCs. 4. walking economy of patients measured before and after the intervention. The PEDro scale was used to assess the methodological quality of the included studies.

Results and discussion

Twenty-two studies met the inclusion criteria. Meta-analysis results showed that exercise significantly improved WE (g = -0.352, 95% CI, -0.625 to -0.078, P = 0.012). Subgroup analysis revealed that patients who received exercise showed better WE compared with those who underwent no control intervention (g = -0.474, 95% CI, -0.636 to -0.311, P < 0.001). However, exercise therapy did not show a significant improvement of WE compared with control groups (g = -0.192, 95% CI, -0.451 to 0.067, P = 0.146). In addition, we found that endurance combined with resistance, high-intensity intermittent, and other training modalities resulted in better WE compared with the pre-intervention. Of these, interval training has the greatest effect on improving WE. In conclusion, exercise can improve WE in patients with CNCs. More randomized controlled trials are necessary for the future.

Motor and respiratory functions are main challenges to patients with multiple sclerosis

Abstract Introduction People with multiple sclerosis (MS) present wide and varied symptoms. Objective To investigate the impact of MS on subjects’ motor and respiratory functions. Methods One hundred one participants were enrolled in this study. The subjects had previous diagnosis of relapsing-remittent MS (n = 48) or presented no neurologic diseases (n = 53, control group). Assess-ments involved mobility (Timed Get Up and Go) and balance (Berg Balance Scale) tests. A force platform was used to evaluate postural stabilometry. Respiratory functions were assessed with a portable spirometer and a digital manovacuometer. Data analyses were carried out with Student´s t-tests, chi-square, and Pearson correlation index. Significance was set at 5%. Results Compared to control peers, participants with MS showed higher motor dysfunctions affecting mobility, balance, and postural stability. Spirometry indicated normal parameters for pulmonary flows and lung capacities in both groups. The manovacuometer, differently, pointed to a respiratory muscle weakness in 48% of participants with MS. Correlation analyses highlighted that respiratory functions are more associated to dynamic than to static motor tests. Conclusion Pathological changes in MS lead to motor dysfunction on mobility, balance and postural stability. Respiratory tests showed normal pulmonary flows and lung capacities in patients with MS, but with commitment of respiratory muscle strength. Respiratory functions were more impacted by dynamic tasks rather than static motor tasks.

Capturing cognitive changes in multiple sclerosis by performance-based functional and virtual reality assessments

Cognitive impairment (CI) has been recognized as one of the core multiple sclerosis (MS) symptoms that profoundly impact lives of people with MS (PwMS). Clinical trials have begun to focus on cognition as a primary or secondary outcome, but translating improvements in cognitive testing scores to functioning in the real world is difficult. Performance-based functional assessments and virtual reality (VR) assessments, which incorporate real-world challenges, have been proposed as a way to better assess functional cognition (i.e., cognitive performance and its impact on real-life cognitive functioning of PwMS) and could address the difficulty in evaluating the impact of a treatment on real-world functioning. In this narrative review, we identify and summarize some of the promising recent research applications of performance-based functional assessments and VR tools to assess functional cognition in MS. Overall, most of the studies suggest that functional and VR assessments can detect cognitive differences between people with and without MS and between PwMS with and without CI. Furthermore, performance on some of the functional and VR assessments was associated with performance on standard cognitive assessments. However, developing any guidelines on how to implement these assessments in clinical practice is difficult because of the relatively small sample size across these studies. Performance-based functional and VR assessments represent an innovative approach to increasing sensitivity of how cognitive impairments/abilities present in the daily life of PwMS. More studies, with a larger sample size, robust research methods, and pre- and post-treatment assessments, are warranted to validate relevant, accessible functional and VR assessments before implementing these assessment approaches in clinical practice.

Health-related quality of life of patients with multiple sclerosis: Analysis of ten years of national data

BACKGROUND

Multiple sclerosis (MS) is a progressive autoimmune disease of the central nervous system. Both the physical and mental burden of MS affect patients' health-related quality of life (HRQoL). However, there is limited research at the national level evaluating the humanistic burden among MS patients.

OBJECTIVES

This study evaluated the HRQoL and functional limitations among MS patients using ten years of national survey data.

METHODS

Guided by the conceptual framework of the Wilson and Cleary model, this study compared HRQoL between adults diagnosed with MS (Clinical Classification Code= "080″) and non-MS adults using the 2006-2015 Medical Expenditure Panel Survey (MEPS) data. The humanistic burden included HRQoL and functional limitations. The HRQoL was evaluated using physical component summary (PCS) and mental component summary (MCS) based on the Short Form Health Survey (SF-12). The study applied the multivariable Generalized Linear Models (GLM) to estimate the marginal differences in PCS and MCS based on the SF-12. In addition, seeking help for activities of daily living (ADL) and instrumental activities of daily living (IADL) were modeled with multivariable logistic regression.

RESULTS

According to the MEPS, the estimated annual prevalence of MS was 0.52 million (95% Confidence Interval [CI]: 0.42-0.60). MS patients were mainly female (71.90%), middle aged (50-64 years, 40.21%), non-Hispanic whites (78.29%), and enrolled in private insurance plans (68.93%). The average PCS scores in MS and non-MS groups were 35.70 and 49.48, respectively. The average MCS scores were 45.58 and 51.25 for MS and non-MS groups, respectively. In addition, 18.26% of MS patients sought help for ADL, and 27.08% sought help for IADL. After adjusting for individual, biological, and environmental characteristics, the multivariable GLM with Poisson distribution indicated that the marginal difference of PCS score was 11.10 (95% CI: 9.50-12.61) units lower, and the MCS score was 4.89 (95% CI: 3.44-6.30) units lower among MS patients. In addition, MS patients were 17.32 (95% CI: 11.61-25.84) and 14.43 (95% CI: 10.09-20.65) times more likely to request assistance for ADL and IADL, respectively.

CONCLUSIONS

MS was associated with lower physical and mental HRQoL than their non-MS counterparts and MS patients were more likely to request help for ADL and IADL. More work is needed to evaluate the effect of treatment strategies on improving the HRQoL and functional limitations in MS.

Performance of Activities of daily living in people with multiple sclerosis

OBJECTIVE

Multiple sclerosis (MS) may result in activity and participation limitations, including the performance of activities of daily living (ADL). This study aims at systematically investigate ADL performance by using Assessment of Motor and Process Skills (AMPS) in people with MS (PwMS) of all disease types and within the Kurtzke Expanded Disability Status Scale (EDSS) range from 1.0 - 8.0.

METHODS

Eight multiple sclerosis (MS) centres participated in data collection of a consecutive sample of PwMS. Participants were referred for assessment to occupational therapy (OT) by treating physician or recruited from neurology department in each hospital and assessed by EDSS and AMPS. The AMPS is an observational, criterion referenced ADL assessment, providing values for a person's ADL performance in terms of motor and process skills. Criterion referenced cut-off scores were established at 2.0 for motor skills and at 1.0 for process skills and both values above the cut-off score indicate competent (independent, safe, efficient and effortless) ADL performance. Process skills refer to the act of carrying out a series of actions and is summarized in terms of efficiency, like initiating without pauses, continuing actions through to completion, performing actions in logical order (sequences), choosing, and completing the task as planned (heeds).

RESULTS

Two hundred and ten PwMS were recruited (48 +/- 13 years of age, 145 women/65 men, average disease duration was 11.8 +/- 9.6 years, average EDSS was 4.8+/-1.8). Average motor skills score was 1.01+/- 1.12 (indicating need for assistance with evidence of increased clumsiness/physical effort) and average process skills score was 1.02 +/- 0.66 (risk zone, questionable efficiency and more likely to need assistance). Overall, motor skills and process skills decreased with increasing EDSS score. No need for assistance in motor skills was indicated in subjects with lower EDSS scores (1.0 - 2.5). In higher EDSS group (≥4.5), 57% of subjects needed assistance in motor skills and 27% in process skills. The competency in process skills was either questionable or reduced within all EDSS scores. However, 33-38% of subjects with higher EDSS scores (6.0-8.5) showed competent performance in process skills. Overall correlation between motor and process scores was moderate (r = 0.56, p<0.0001), but no significant relationships between motor and process skills were found in the lower EDSS (1-2.5) and high EDSS scores (8-8.5). Further, EDSS and disease type were significant predictors, explaining 52.7% of motor skills and 22.3% of process skills performance.

CONCLUSION

Problems in ADL performance were found in EDSS categories 1.0 to 8.0 and in all disease types, therefore it is advisable to screen all PwMS for ADL deficits and provide relevant rehabilitation interventions.

Advancing motor rehabilitation for adults with chronic neurological conditions through increased involvement of kinesiologists: a perspective review

Many people with neurological conditions experience challenges with movement. Although rehabilitation is often provided acutely and sub-acutely following the onset of a condition, motor deficits commonly persist in the long-term and are exacerbated by disuse and inactivity. Notably, motor rehabilitation approaches that incorporate exercise and physical activity can support gains in motor function even in the chronic stages of many neurological conditions. However, delivering motor rehabilitation on a long-term basis to people with chronic neurological conditions is a challenge within health care systems, and the onus is often placed on patients to find and pay for services. While neurological motor rehabilitation is largely the domain of physical and occupational therapists, kinesiologists may be able to complement existing care and support delivery of long-term neurological motor rehabilitation, specifically through provision of supported exercise and physical activity programs. In this perspective style review article, we discuss potential contributions of kinesiologists to advancing the field through exercise programming, focusing on community-based interventions that increase physical activity levels. We conclude with recommendations on how kinesiologists' role might be further optimized towards improving long-term outcomes for people with chronic neurological conditions, considering issues related to professional regulation and models of care.

Understanding the impact of cognitive impairment and disease severity on activities of daily living in MS patients with different disability levels

OBJECTIVE

Physical impairments seen in people with multiple sclerosis (PwMS) affect the level of independence in activities of daily living (ADL). However, physical problems are insufficient to explain some debilitating conditions experienced by PwMS in daily life, especially in activities that require high cognitive ability. The aim of this study was to investigate the impact of cognitive impairment and disease severity on ADL in MS patients with different disability levels.

METHODS

Seventy PwMS were enrolled and divided into three groups according to their disability status. Cognitive functions were assessed with the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) and independence level in ADL was assessed with Functional Independence Measure (FIM).

RESULTS

There were significant differences between groups in FIM and FIM motor (FIMm) scores (p < 0.001), however no significant differences were found between groups in terms of FIM cognitive (FIMc) and LOTCA scores (p = 0.195 and p = 0.348 respectively). There was a moderate positive correlation between FIM and LOTCA total scores (p < 0.001) for overall sample. While there was a low correlation between LOTCA and FIMm (p = 0.008), high correlation was found between LOTCA and FIMc (p < 0.001).

CONCLUSION

Although most of the limitations in ADL can be explained by the severity of the disability in MS, the ability to perform ADL including cognitive skills was found to be similar for all disability levels. Cognitive problems should be taken into consideration as well as motor problems in the process of planning treatment programs for PwMS with any levels of disability.

The International Classification of Functioning, Disability, and Health (ICF) as a community participation model for people with multiple sclerosis: A hierarchical regression analysis

Multiple sclerosis (MS) is a central nervous system disorder that impacts more than 400,000 people in the U.S. The disease results in multiple functional impairments that are diverse and varied across individuals. Additonally, MS has a profound impact on community participation which, like other rehabilitation outcomes, cannot be explained on the basis of functional limitations alone. The purpose of this study was to develop and evaluate a model of community participation for people living with MS using the World Health Organization (WHO) International Classification of Functioning, Disability, and Health (ICF) framework. The model focused on the roles that personal factors have as predictors of community participation, while also serving as mediators and moderators for the relationship between activity limitation and participation. Results from the hierarchical regression analysis indicated that demographic characteristics (i.e. MS type), personal factors (i.e. core self-evaluations (CSE), MS self-management, resilience, and social skills), and activity limitations accounted for 64% of the variance in participation. Further, mediation analysis indicated that CSE mediated the relationship between activity limitation and community participation. Finally, moderation analysis indicated an interaction effect between educational attainment and MS self-management. Implications for future research in rehabilitation and clinical application are discussed.

A Descriptive Cross-Sectional Study of Manipulative Dexterity on Different Subtypes of Multiple Sclerosis

Background

Manipulative dexterity impairments affect 76% of individuals with multiple sclerosis (MS). Patients with MS can experience reduced skill when performing both basic activities of daily living and instrumental activities of daily living. Many studies consider that physical rehabilitation leads to a decrease in the level of disability, especially at the mild and moderate stages of the disease. However, most studies fail to distinguish between the different MS subtypes.

Purpose

Our aims were (1) to describe the manipulative skills of people according to the different subtypes of MS, (2) to analyze the correlation between dexterity and self-perception variables, and (3) to identify possible predictors of functionality. Study Design. A descriptive cross-sectional study.

Methods

30 individuals with MS. The measurement tools used were the ABILHAND, the Purdue Pegboard Test (PPT), the Nine-Hole Peg Test, and the Box and Block Test.

Results

All subtypes of MS obtained lower scores for manipulative dexterity compared to normal skill levels, with individuals with primary progressive MS displaying the lowest values. However, the analysis of differences between the different subtypes did not reveal statistically significant intragroup differences. In addition, differences were found regarding the effect size of practically all the variables analyzed for both manipulative dexterity (PPT, NHPT, and BBT) and the self-perception of ADLs (ABILHAND), for which high values (d _r = 0.72) and very high values (d _r = 1.46) were obtained.

Conclusions

Although no significant differences were found between the different types of MS, the assessment of manual dexterity and perceived efficacy of daily activities must be considered as prognostic factors in the progression of the disease. These findings may help support further research on targeted interventions to improve dexterity deficiencies, as well as promote an improved quality of therapeutic interventions.

New applications for independent activities of daily living in measuring disability in multiple sclerosis

BACKGROUND

Disability outcome measures in multiple sclerosis (MS) focus heavily on ambulation; however, limitations in performing everyday activities encompass another type of disability.

OBJECTIVES

The aim of this study was to examine the ability of instrumental activities of daily living (IADL) scale to discriminate between different levels of disability and to predict disability progression.

METHODS

The North American Research Committee on Multiple Sclerosis (NARCOMS) registry fall 2006 semi-annual survey asked participants to complete the RAND-12, Performance Scales, Patient Determined Disease Steps (PDDS), and IADL questionnaires. We modeled the trajectory of disability change, using the PDDS, over 12 years. Analyses used linear and repeated measures regression methods.

RESULTS

Of respondents (n = 9931), 9559 (96%) completed the PDDS and IADL scale. Respondents were mostly female (76%), Caucasian (92%), and 52.3 (10.5) years old with moderate disability (median PDDS 4 (early cane)). Mean (SD) IADL total score was 20.5 (3.7). Discriminant ability of the IADL scale was higher than other measures considered at higher levels of disability. Adjusted longitudinal models showed that needing greater assistance on IADLs was independently predictive of trajectories of greater disability change.

CONCLUSION

IADL scale had a greater ability to discriminate between higher disability levels than RAND-12 domains. The IADL scale may provide a useful and clinically relevant tool to measure disability in progressive MS populations.

Evaluating functional electrical stimulation (FES) cycling on cardiovascular, musculoskeletal and functional outcomes in adults with multiple sclerosis and mobility impairment: A systematic review

BACKGROUND

People with Multiple Sclerosis (PwMS) are at an increased risk of diseases associated with low levels of physical activity (PA). Deconditioning may lead to an acceleration in the development of secondary complications from MS, impairing physical function and exacerbating disease progression. Functional Electrical Stimulation (FES) Cycling may provide a suitable lower limb exercise intervention for PwMS with mobility impairment. The effects of FES cycling on cardiovascular, musculoskeletal and functional outcomes for PwMS with mobility impairment are yet to be investigated to date.

OBJECTIVE

The objective of this review was to systematically examine the outcomes of PwMS with mobility impairment following FES cycling intervention.

METHODS

A systematic search of four electronic databases (MEDLINE, Web of Science, CINAHL and PEDro) from their inception to 8th January 2019 was performed. Inclusion criteria was (1) include human participants with definite diagnosis of MS (2) participants had to be aged 18 years or older (3) include participants with mobility impairment (determined as an average participant EDSS ≥ 6.0) (4) evaluate FES cycling as an intervention study.

RESULTS

Initial searches found 1163 studies. 9 of which met the full inclusion criteria: 5 pre-post studies with no control group, 2 randomised controlled trials (RCTs), 1 retrospective study and 1 case study. Two studies had the same participant group and intervention but reported different outcomes. Outcome data was available for n = =76 unique participants, with n = =82 completing a FES cycling intervention. Of the n = =4 papers with clear dropout rates, pooled dropout rate was 25.81%. Two papers reported non-significant improvements in aerobic capacity following a FES cycling intervention. Four papers reported no change in lower limb strength and two papers reported significant reductions in spasticity post training. Four studies failed to provide information regarding adverse events with the other studies reporting n = =10 adverse events across 36 participants.

CONCLUSION

Findings suggest FES cycle training may reduce CVD risk alongside trends for a reduction in spasticity post training, however the low quality of the literature precludes any definitive conclusions. FES cycle training appears to be well tolerated in PwMS with mobility impairment, with no serious adverse events.

The Association between ADL Ability and Quality of Life among People with Advanced Cancer

BACKGROUND

Occupational therapy and occupational science are founded on the theoretical core assumption that occupation and quality of life (QoL) are closely related. However, such theoretical core assumptions must be supported through empirically based research.

OBJECTIVE

To investigate the association between QoL and occupation, here self-reported and observed ADL abilities as a part of occupation, among people with advanced cancer, including determining whether self-reported or observed ADL ability had the stronger association with QoL.

METHODS

The study was nested in a cross-sectional study. The association between ADL ability and QoL among 108 people with advanced cancer was investigated using the ADL Interview (ADL-I), the Assessment of Motor and Process Skills (AMPS), and the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC-QLQ-C30).

RESULTS AND CONCLUSIONS

Results showed that high observed ADL motor ability was associated with high QoL. In contrast, observed ADL process ability and self-reported ADL ability were not significantly associated with QoL. Oppositely expected, observed ADL ability had a stronger association with QoL than self-reported ADL ability. Thereby, the study to some extent contributes knowledge confirming the theoretical core assumptions about the relation between occupation, here performance of ADL, and QoL.

Tablet App Based Dexterity Training in Multiple Sclerosis (TAD-MS): Research Protocol of a Randomized Controlled Trial

Introduction: Patients with Multiple Sclerosis exhibit disturbed dexterity, leading to difficulties in fine motor skills such as buttoning a T-shirt or hand-writing. Consequently, activities of daily living and quality of life are affected. The aim of the present study is to investigate the effectiveness of a tablet app-based home-based training intervention to improve dexterity in patients with Multiple Sclerosis. Methods: An observer-blinded randomized controlled trial will be performed. Seventy patients with Multiple Sclerosis with self-reported difficulties in dexterity while executing activities of daily living will be recruited. After baseline assessment, participants are randomized to either an intervention group (n = 35) or control group (n = 35) by a computerized procedure. Blinded assessments will be done at baseline, post-intervention (after 4 weeks) and 12 weeks follow-up. The home-based intervention consists of a 4-week tablet app-based dexterity program. The app contains six dexterity games in which finger coordination, tapping, pinch grip is required. The control group will receive a Thera-band training program focused on strengthening the upper limb. The primary outcome is the Arm function of Multiple Sclerosis Questionnaire, a measure of patient-reported activities of daily living related dexterity. Secondary outcomes are dexterous function, hand strength, and quality of life. Discussion: This study will evaluate the effects of tablet app-based training for dexterity in patients with Multiple Sclerosis. We hypothesize that a challenging app-based dexterity program will improve dexterity both in the short term and the long-term. The improved finger and hand functions are expected to generalize to improved activities of daily living and quality of life.

Aerobic Fitness and Instrumental Activities of Daily Living in People with Multiple Sclerosis: A Cross-sectional Study

Background

There is ample evidence that aerobic fitness is reduced in people with multiple sclerosis (MS), and this may yield a reduction in independence in instrumental activities of daily living (IADLs). This study examined the association between aerobic fitness and self-reported IADLs in persons with MS.

Methods

Sixty-two adults with MS completed an incremental exercise test as a measure of aerobic fitness (peak oxygen consumption), a demographic questionnaire, and an IADL scale and underwent a neurologic examination for characterization of disability level (ie, Expanded Disability Status Scale) in a single session.

Results

The analysis revealed a weak but significant association between aerobic fitness and total IADL score (r = 0.28 [95% CI, 0.03-0.49], P = .033). Those reporting dependence in different IADL categories (eg, shopping, food preparation, housekeeping, laundry, and responsibility for own medication) presented with lower aerobic fitness compared with those reporting independence, although the difference was not statistically significant.

Conclusions

These findings extend previous studies on activities of daily living in people with MS and underscore the need for studies examining the potential effect of aerobic exercise interventions on independence regarding IADLs in this population.

Tasks of activities of daily living (ADL) are more valuable than the classical neurological examination to assess upper extremity function and mobility in multiple sclerosis

BACKGROUND

Accurate clinical assessment in multiple sclerosis (MS) is challenging. The Assess MS system is being developed to automatically quantify motor dysfunction in MS, including upper extremity function (UEF) and mobility.

OBJECTIVE

To determine to what extent combinations of standardized movements included in the Assess MS system explain accepted measures of UEF and mobility.

METHODS

MS patients were recruited at four European MS centres. Eight movements were selected, including tasks of activities of daily living (ADL) and classical neurological tests. Movements were recorded on video and rated by experienced neurologists (n = 5). Subsequently, multivariate linear regression models were performed to explain the variance of the Nine-Hole Peg Test (9HPT), Arm Function in Multiple Sclerosis Questionnaire (AMSQ) and Timed-25 Foot Walk test (T25WT).

RESULTS

In total, 257 patients were included. The movements explained 62.9% to 80.1% of the variance of the 9HPT models, 43.3% and 44.3% of the AMSQ models and 70.8% of the T25WT. In all models, tasks of ADL contributed most to the variance.

CONCLUSION

Combinations of movements are valuable to assess UEF and mobility. Incorporating ADL tasks into daily clinical practice and clinical trials may be more valuable than the classical neurological examination of UEF and mobility.

Minimum number of days required for a reliable estimate of daily step count and energy expenditure, in people with MS who walk unaided

BACKGROUND AND PURPOSE

The purpose of this study was to examine the minimum number of days needed to reliably estimate daily step count and energy expenditure (EE), in people with multiple sclerosis (MS) who walked unaided.

METHODS

Seven days of activity monitor data were collected for 26 participants with MS (age=44.5±11.9years; time since diagnosis=6.5±6.2years; Patient Determined Disease Steps=≤3). Mean daily step count and mean daily EE (kcal) were calculated for all combinations of days (127 combinations), and compared to the respective 7-day mean daily step count or mean daily EE using intra-class correlations (ICC), the Generalizability Theory and Bland-Altman.

RESULTS

For step count, ICC values of 0.94-0.98 and a G-coefficient of 0.81 indicate a minimum of any random 2-day combination is required to reliably calculate mean daily step count. For EE, ICC values of 0.96-0.99 and a G-coefficient of 0.83 indicate a minimum of any random 4-day combination is required to reliably calculate mean daily EE. For Bland-Altman analyses all combinations of days, bar single day combinations, resulted in a mean bias within ±10%, when expressed as a percentage of the 7-day mean daily step count or mean daily EE.

CONCLUSIONS

A minimum of 2days for step count and 4days for EE, regardless of day type, is needed to reliably estimate daily step count and daily EE, in people with MS who walk unaided.

Psychometric evaluation of the Finnish version of the impact on participation and autonomy questionnaire in persons with multiple sclerosis

OBJECTIVE

The objective of this study was to evaluate the psychometric properties of the impact on participation and autonomy (IPA) questionnaire. The Finnish version of IPA (IPAFin) was translated into Finnish using the protocol for linguistic validation for patient-reported outcomes instruments.

METHODS

A total of 194 persons with multiple sclerosis (MS) (mean age 50 years SD 9, 72% female) with moderate to severe disability participated in this study. A confirmatory factor analysis (CFA) was used to confirm the four factor structure of the IPAFin. The work and educational opportunities domain was excluded from analysis, because it was only applicable to 51 persons. Internal consistency was investigated by calculating Cronbach's alpha.

RESULTS

CFA confirmed the construct validity of the IPA (standardized root mean square residual (SRMR) = 0.06, comparative fit index (CFI) = 0.93, Tucker-Lewis index =0.93, root mean square error of approximation (RMSEA) = 0.06), indicating a good fit to the model. There was no difference in the models for females and males. Cronbach's alpha for the domains ranged between 0.80 and 0.91, indicating good homogeneity.

CONCLUSIONS

The construct validity and reliability of the IPAFin is acceptable. IPAFin is a suitable measure of participation in persons with MS.

Exploring Occupational Adaptation through the Lives of Women with Multiple Sclerosis

Multiple sclerosis (MS) affects people's physical capabilities and the lives of people with MS are constantly changing (Finlayson et al 2005), yet how people adapt to the disease from an occupational perspective has received little attention. This study explored the occupational adaptation of women with MS.

Seven women with MS were recruited from the Multiple Sclerosis Society of Ireland. Each participant completed the Modified Interest Checklist (Kielhofner and Neville 1983), the Role Checklist (Oakley et al 1985) and the Occupational Questionnaire (Smith et al 1986). Qualitative data were also collected, using the Occupational Performance History Interview – II (Kielhofner et al 2004).

The findings from all four tools were amalgamated and analysed. Three main themes emerged: the impact of MS on (i) performance capacity, (ii) roles and (iii) interests. The participants adapted by performing interests and roles differently and developing new meaningful interests and roles that were congruent with their performance capacity.

The findings highlight the importance of having an understanding of the impact of different types of MS on the occupational adaptation process. A greater understanding will facilitate occupational therapists in enabling people with MS to adapt to their condition by engaging in meaningful occupations throughout the lifespan.

Measurement properties of the Arm Function in Multiple Sclerosis Questionnaire (AMSQ): a study based on Classical Test Theory

PURPOSE

The construct validity, test-retest reliability, and measurement error of the Arm Function in Multiple Sclerosis Questionnaire (AMSQ) were examined. Additionally, the influence of administration-method on reliability and measurement error was investigated.

METHOD

112 Dutch adult MS-patients from an academic- and a residential care-facility participated. Questionnaires were administered on paper, online or as interview, and patients performed several performance tests. Construct validity was assessed by testing pre-defined hypotheses. Reliability was assessed using Intraclass Correlation Coefficients (ICCs), Standard Error of Measurements (SEMs) and Smallest Detectable Changes (SDCs).

RESULTS

For construct validity (N = 105) 9 of 13 hypotheses were confirmed (69%). As expected, the AMSQ showed moderate to strong relationships with the instruments measuring similar constructs. The test-retest reliability coefficient was 0.96 (95% Confidence Interval 0.94-0.97); SEM was 6.3 (6.3% of scale range); SDC was 17.5 (on a sale from 0 to 100). Different administration-methods showed good reliability (ICC 0.88-0.94) and small standard errors (SEM 5.6-7.2).

CONCLUSION

The AMSQ shows satisfying results for validity and excellent reliability; allowing for proper use in research. Due to a large SDC value, caution is needed when using the AMSQ in individual patient care. Further research should determine whether the SDC is smaller than the minimal important change. Implications for Rehabilitation The Arm Function in Multiple Sclerosis Questionnaire (AMSQ) measures activity limitations due to hand and arm functioning in patients with Multiple Sclerosis (MS). Results of this study confirm adequate validity and reliability of the AMSQ in patient with MS. The equivalence of scores from online, paper or interview administration is supported. A change score of ≥18 points on the scale of the AMSQ (on a scale 0-100) needs to occur to be certain a change beyond measurement error has occurred in an individual patient.

Activities of daily living and social activities in people with multiple sclerosis in Stockholm County

Objective: To describe independence in personal and instrumental activities of daily living (ADL), and frequency of social/lifestyle activities in a population-based sample of people with multiple sclerosis in Stockholm.

Design: Population-based survey.

Setting: Data collection in home environment.

Subjects: One hundred and sixty-six people with multiple sclerosis.

Interventions: Data were collected using measurements and structured interviews.

Main measures: Independence in ADL was assessed by the Barthel Index; independence in personal and instrumental ADL by the Katz Extended ADL Index; and frequency of social/lifestyle activities by the Frenchay Activities Index.

Results: The mean age was 519 ± 12 years in the included 166 people with multiple sclerosis, of whom 71% ( n = 118) were women. Fifty-two per cent ( n = 85) were independent in personal ADL, 30% ( n = 50) in instrumental ADL, and 35% ( n = 57) had normal frequency of social/lifestyle activities. Most frequently affected ADL items were cleaning indoors and outdoors transportation (62%, n = 102) and the social/lifestyle items of household maintenance (59%, n = 97), walking outside (59%, n = 97), heavy housework (61%, n = 100), and gardening (68%, n = 112).

Conclusions: ADL and social/lifestyle activities were affected in two-thirds of people with multiple sclerosis in Stockholm. The most affected items were items that could be classified as mobility-related and physically demanding, underlining the importance of developing and using evidence-based exercise treatments and rehabilitation to increase independence in people with multiple sclerosis in Stockholm.

Home functioning profiles in people with multiple sclerosis and their relation to disease characteristics and psychosocial functioning

BACKGROUND

For people with multiple sclerosis (MS), limitations in performing activities of daily living can have a significant impact on personal independence, residential safety, and quality of life. In this study we explored the utility of the Home Functioning Scale in identifying home functioning profiles and generating rehabilitation interventions.

OBJECTIVE

The objective of this study was to determine whether distinctive and meaningful home functioning profiles could be identified among adults with MS based on Home Functioning Scale scores.

METHODS

Home Functioning Scale scores and additional data from a representative national sample of 3,834 adults were analyzed. We used cluster analysis and MANOVA to identify and evaluate group differences.

RESULTS

Three distinct home functioning profiles emerged in the analysis: (1) minimal impairment (31.1% of participants); (2) moderate impairment (52.4%); and (3) severe impairment (16.5%). The three groups exhibited significant differences on demographic and MS related characteristics, perceived cognitive function, perceived MS impact on physical and psychological function, and life satisfaction.

CONCLUSION

The profile characteristics of the identified groups are presented and the implications of the results for rehabilitation practitioners and the investigation of home functioning in activities of daily living are discussed.

The Arm Function in Multiple Sclerosis Questionnaire (AMSQ): development and validation of a new tool using IRT methods

PURPOSE

We developed the Arm Function in Multiple Sclerosis Questionnaire (AMSQ) to measure arm and hand function in MS, based on existing scales. We aimed at developing a unidimensional scale containing enough items to be used as an itembank. In this study, we investigated reliability and differential item functioning of the Dutch version.

METHOD

Patients were recruited from two MS Centers and a Dutch website for MS patients. We performed item factor analysis on the polychoric correlation matrix, using multiple fit-indices to investigate model fit. The graded response model, an item response theory model, was used to investigate item goodness-of-fit, reliability of the estimated trait levels (θ), differential item functioning, and total information. Differential item functioning was investigated for type of MS, gender, administration version, and test length.

RESULTS

Factor analysis results suggested one factor. All items showed p-values of the item goodness-of-fit statistic above 0.0016. The reliability was 0.95, and no items showed differential item functioning on any of the investigated variables.

CONCLUSION

AMSQ is a unidimensional 31-item questionnaire for measuring arm function in MS. Because of a well fit in a graded response model, it is suitable for further development as a computer adaptive test. Implications for Rehabilitation A new questionnaire for arm and hand function recommended in people with multiple sclerosis (AMSQ). Scale characteristics make the questionnaire suitable for use in clinical practice and research. Good reliability. Further development as a computer adaptive test to reduce burden of (repetitive) testing in patients is feasible.

A pilot mixed methods investigation of the use of Oswestry standing frames in the homes of nine people with severe multiple sclerosis

PURPOSE

People with multiple sclerosis (MS) commonly experience muscle weakness which limits their ability to stand. Supported standing may minimise the secondary complications of prolonged sitting but evidence for this is scarce. This study investigated the effects of regular standing in an Oswestry frame on some secondary complications of immobility and explored the lived experience of standing.

METHODS

Nine people with MS participated in a mixed-methods study over 48 weeks. Single-case experiments were used. Outcomes included: Amended Motor Club Assessment, Canadian Occupational Performance Measure, Penn Spasm Scale, bowel frequency and a numerical pain-scale. The qualitative strand used a case-study approach with a phenomenological perspective.

RESULTS

Significant improvements (p < 0.05) were demonstrated for individuals in strength, ADL and spasms but not in bowel frequency or pain. Subjective improvements occurred in continence, clonus and fall-rate. Being upright or strengthened by standing enabled participants to re-engage with activities and re-establish themselves within relationship roles. This engendered a sense of achievement and increased optimism.

CONCLUSION

This study provides preliminary evidence of the effectiveness of regular frame-standing in improving strength, function, spasms, continence and fall-rate in people with severe MS. Standing reinstated a sense of belonging and optimism by restoring important life-roles and feelings of normality as participants regained previously valued activities. Implications for Rehabilitation Regular standing in an Oswestry frame may improve functional ability in people with severe MS. Regular frame standing may have a positive psychological effect on people with severe MS. Self-management of a standing regime may be feasible.

Activities of daily living and self-care agency in patients with multiple sclerosis for the first 10 years

PURPOSE

The aim of the study was to present the effects of the disease and analyze the relationship between activities of daily living (ADL) and self-care in multiple sclerosis (MS) patients who have had the disease for the first 10 years.

DESIGN

This study was a descriptive cross-sectional study.

METHODS

A total of 67 patients who fit the inclusion criteria of the study and volunteered to participate were included in the sample. Data were collected using the Exercise of Self-Care Agency Scale and the Barthel Index.

FINDINGS

The mean age was 38.43±9.92. There was a statistically significant correlation between participants'educational backgrounds and self-care scores and between disease duration and Barthel index score (p<.05).

CONCLUSIONS

The self-care levels of patients who have had MS for the first 10 years are medium, and they tend to be mildly dependent in performing their ADL. The duration of MS is positively correlated with level of ADL.

CLINICAL RELEVANCE

In this study, it was shown that the duration of the disease in MS patients should be taken into account by rehabilitation nurses to implement effective nursing care.

Assessing upper limb function in multiple sclerosis

The need to fully assess upper limb function in multiple sclerosis (MS) has become increasingly clear with recent studies revealing a high prevalence of upper limb dysfunction in persons with MS leading to increased dependency and reduced quality of life. It is important that clinicians and researchers use tailored outcome measures to systematically describe upper limb (dys)function and evaluate potential deterioration or improvement on treatment. This topical review provides a comprehensive summary of currently used upper limb outcome measures in MS, classified according to the levels of the International Classification of Functioning (ICF). The clinical utility, strengths, weaknesses and psychometric properties of common upper limb outcome measures are discussed. Based on this information, recommendations for selecting appropriate upper limb outcome measures are given. The current shortcomings in assessment which need to be addressed are identified.

Dexterity, visual perception, and activities of daily living in persons with multiple sclerosis

ABSTRACT The purposes of this study were to compare dexterity, visual perception, and abilities to carry out activities of daily living (ADL) in persons with different multiple sclerosis (MS) subtypes and to determine what relationships exist between the three variables. Fifty-six persons with MS were administered tests of dexterity, visual perception, and ADL ability. Demographic variables and scores on Kurtzke's Expanded Disability Status Scale were also collected. Scores from the chronic-progressive group were significantly higher than those of the benign and progressive-relapsing groups for the Nine-Hole Peg Test-Left Hand, Grooved Peg Test, and Functional Status Index (except Functional Status Index-Pain). There were no differences between the MS groups for any demographic variables except on the Expanded Disability Status Scale. Visual perception did not correlate with dexterity or ADL ability, and only dexterity scores for the left hand correlated with ADL ability. Persons with the severer subtype of MS were significantly impaired compared with the least severe group for dexterity and ADL ability. Decreased dexterity was associated with needing more assistance and having more perceived difficulty with ADL.

Self-perceived performance and satisfaction with performance of daily activities in persons with multiple sclerosis following interdisciplinary rehabilitation

PURPOSE

To assess self-perceived performance and satisfaction with performance of daily activities in persons with multiple sclerosis (MS) on admission to and at discharge from interdisciplinary rehabilitation.

METHOD

A retrospective study with a pre-post design. Twenty-seven women and 16 men with MS (mean age 51 years; median EDSS 6.5) participated in an individualised, goal-oriented, interdisciplinary, rehabilitation programme (average length 4 weeks). The Canadian Occupational Performance Measure (COPM) was used on admission to rehabilitation and at discharge.

RESULTS

On admission, the persons prioritised 216 activities that they perceived difficult to perform (mean number 3, range 2-8). Of these, 136 (63%) were in the COPM area of self-care, 52 (24%) in productivity and 28 (13%) in leisure. The lowest mean ratings of performance were found in the subgroups active recreation, community management and socialisation, and for satisfaction in the subgroup socialisation. For about 60% of the 216 prioritised activities, ratings of COPM performance as well as satisfaction were higher at discharge than on admission. For 18 (42%) and 24 (56%) persons, respectively, the mean change scores of performance and of satisfaction were equal to or greater than 2.0 at discharge, indicating a clinically significant change.

CONCLUSIONS

Persons with MS can experience problems with all types of daily activities upon admission to rehabilitation, but also perceive improvements in their performance and satisfaction with performance in these activities at discharge from rehabilitation. Using patient-reported outcome measures, such as the COPM, may contribute to a broader understanding of the benefits of interdisciplinary rehabilitation in persons with MS. Implications for Rehabilitation Persons with MS can perceive problems with all types of daily activities which have to be considered during interdisciplinary rehabilitation. Following interdisciplinary rehabilitation, persons with MS can perceive improvements in their performance and satisfaction with performance in all types of daily activities. Patient-reported outcome measures can contribute to a broader understanding of the benefits of interdisciplinary rehabilitation in persons with MS.

HIV and disability: a pilot study exploring the use of the Assessment of Motor and Process Skills to measure daily life performance

Introduction

Limitations in performing activities of daily living (ADL) are important indicators of health and overall wellness, yet relatively few studies specifically identify the ADL abilities of people living with HIV/AIDS (PHAs). Given the wide range of abilities and ages of PHAs, there is an urgent need to utilize an assessment of ADL ability that can validly evaluate those who are very able, as well as those who are very disabled, without the presence of ceiling or floor effects, to provide sensitive measures to detect change.

Purpose

The purpose of this study was to gather preliminary evidence of the validity of using the Assessment of Motor and Process Skills (AMPS) with PHAs.

Methods

By utilizing existing data records of PHAs from the international AMPS database, we explored (a) demographic factors; (b) person response validity by examining person and individual item goodness-of-fit to the AMPS measurement model; and (c) trends in ADL abilities of PHAs.

Findings

There were 137 data records in the international AMPS database (0.08% of the database). Goodness-of-fit analyses revealed that >90% of the individuals in the sample fit AMPS measurement model and >99% of the individual item ratings fit the model. More than 80% of the data record had ADL motor abilities that were significantly lower than age expectations, and 67% had ADL process ability measures that were significantly lower than age expectations.

Conclusions

The findings indicate that the AMPS is a valid measure of ADL ability for PHAs. Coupled with the lower than expected number of AMPS data records for PHAs and the significant ADL ability challenges that were encountered by this sample, this pilot study may indicate that PHAs encounter barriers to accessing rehabilitation services and/or may not receive referrals until significant ADL challenges are encountered.

[Spasticity and everyday life in multiple sclerosis]

Spasticity is one of the most commonly seen symptoms in patients with multiple sclerosis. However, evaluation of the symptom often uses clinical scales that do not incorporate its impact on activities of daily living and quality of life. The everyday life of patients is affected primarily in actions related to mobility and walking capacity, such as the use of transport, gardening, household activities and, ultimately, basic activities such as bathing and dressing. Yet, so far, no study has described the impact of spasticity on the daily life of patients with multiple sclerosis. Nevertheless, assessing the effects of spasticity on such a young population would appear to be essential for meeting the needs of these patients with appropriate therapeutic interventions.

The relationship between walking, manual dexterity, cognition and activity/participation in persons with multiple sclerosis

Background: Multiple sclerosis has a vast impact on health, but the relationship between walking, manual dexterity, cognition and activity/participation is unclear.

Objective: The specific aims were to explore the discriminative ability of measures of walking, manual dexterity and cognition, and to identify cut-off values in these measures, for prediction of independence in personal and instrumental activities of daily living (ADL) and activity/participation in social and lifestyle activities.

Methods: Data from 164 persons with multiple sclerosis were collected during home visits with the following measures: the 2 × 5 m walk test, the Nine-hole Peg Test, the Symbol Digit Modalities Test, the Katz Personal and Instrumental ADL Indexes, and the Frenchay Activities Index (measuring frequency in social and lifestyle activities).

Results: The 2 × 5 m walk test and the Nine-hole Peg Test had high and better discriminative and predictive ability than the Symbol Digit Modalities Test. Cut-off values were identified. The accuracy of predictions was increased above all by combining the 2 × 5 m walk test and the Nine-hole Peg Test.

Conclusion: The proposed cut-off values in the 2 × 5 m walk test and the Nine-hole Peg Test may be used as indicators of functioning and to identify persons risking activity limitations and participation restrictions. However, further studies are needed to confirm the usefulness in clinical practice.

Observation-based assessment of functional ability in patients with chronic widespread pain: a cross-sectional study

Knowledge about functional ability, including activities of daily living (ADL), in patients with chronic widespread pain (CWP) and fibromyalgia (FMS) is largely based on self-report. The purpose of this study was to assess functional ability by using standardised, observation-based assessment of ADL performance and to examine the relationship between self-reported and observation-based measures of disability. A total of 257 women with CWP, 199 (77%) fulfilling the American College of Rheumatology tender point criteria for FMS, were evaluated with the Assessment of Motor and Process Skills (AMPS), an observation-based assessment providing linear measures of ADL motor and ADL process skill ability (unit: logits). A cutoff for effortless and independent ADL task performance is set at 2.0 for the motor scale and 1.0 for the process scale. A total of 248 (96.5%) had ability measures below the 2.00 ADL motor cutoff and 107 (41.6%) below the 1.00 ADL process cutoff, indicating increased effort and/or inefficiency during task performance as well as a potential need of assistance for community living. Mean ADL motor ability measure was 1.07 and was significantly lower in patients diagnosed with FMS than plain CWP (1.02 vs 1.27 logits, P=.001). Mean ADL process ability measure was 1.09 logits and was without difference between FMS and plain CWP (1.07 vs 1.16 logits, P=.064). Only weak to moderate correlations between self-reported functional ability and observation-based AMPS ability measures were observed. The results of the study support the notion of considerable performance difficulties in women with CWP. The everyday life problems are substantial and place the individual at risk of need of support for community living.

Impact of loss of mobility on instrumental activities of daily living and socioeconomic status in patients with MS

OBJECTIVE

To assess the effects of mobility loss on instrumental activities of daily living (IADL) and socioeconomic status in multiple sclerosis (MS) patients.

METHODS

Participants were active registrants in the North American Research Committee on Multiple Sclerosis registry completing the Fall 2006 (IADL analysis, n = 10,396) or Spring 2007 (socioeconomic analysis, n = 8180) surveys. Cross-sectional correlations and linear and logistic regression were performed using sociodemographic factors, mobility scales, and Patient Determined Disease Steps as independent variables and IADLs as the response.

RESULTS

Mobility loss was significantly correlated with decreased IADL scores (r = -0.74; p < 0.0001); this correlation remained significant after adjustment for covariates. Mobility loss also negatively correlated with employment (r = -0.48 for women; r = -0.50 for men, both p < 0.0001) and annual income (r = -0.29; p < 0.0001). These correlations were all significant even with mild mobility loss. The relationships derived from the regression models suggest that the effect of mobility on employment is greater than the effect of demographic variables, and a small but direct effect on annual income that is independent of effects mediated through employment. The self-reported diagnosis of MS for study inclusion and use of single-item ordinal scales for mobility and disability can potentially be criticized as study limitations, although the diagnosis and the scales were previously validated.

CONCLUSION

Mobility loss independently correlated with IADL, and associated with reduced socioeconomic status in people with MS. These correlations were significant with mild mobility loss, supporting early treatment.

The complexity of daily occupations in multiple sclerosis

The aims of this study were to describe which self-care, productivity, and leisure occupations individuals with multiple sclerosis (MS) perceive as difficult to perform on admission to rehabilitation and the individuals' own perception of the importance of, performance of, and satisfaction with these occupations. Whether the reported self-care, productivity, and leisure occupations were related to sex, age, disease severity, and living arrangements was also investigated. Forty-seven men and women (mean age 49.4 years) were assessed with the Canadian Occupational Performance Measure (COPM) on admission to rehabilitation. The individuals reported 366 occupations (median 8, range 3-15), which were categorized as self-care (51%), productivity (30%), and leisure (19%). Three COPM subcategories--household management (26%), personal care (21%), and functional mobility (20%)--accounted for two-thirds of the reported occupations. All prioritized occupations (n = 238; (median 5, range 2-7) had high ratings for importance and the ratings for performance and satisfaction were generally low. Men reported significantly more occupations related to self-care than women, but no significant difference between the sexes could be found for productivity and leisure. No significant differences between the occupational areas were found when age, disease severity, or/and living arrangements were included in the analysis. In conclusion, individuals with MS perceive difficulties with occupations related to all aspects of daily life. This underscores the need to use assessment tools that capture the complexity of daily occupations.

Use of cognitive aids and other assistive technology by individuals with multiple sclerosis

PURPOSE

To investigate the use of assistive technology (AT), unmet needs for AT, and examine correlates of use of memory aids and cognitive strategies among individuals with multiple sclerosis (MS).

METHOD

A cross-sectional study of 1,063 community dwelling adults with MS in Washington State. A self-report survey assessed use of AT as well as depression, fatigue, mobility, and other demographic and disease related variables.

RESULTS

Some 70% of respondents reported using memory strategies and 50.7% reported using electronic memory aids. The strongest correlate of use of electronic memory aids was endorsement of difficulties thinking (OR: 2.09, p < 0.001) though younger age, higher education, and report of higher fatigue were also significant. Fatigue (OR: 1.27, p < 0.001) and depression (OR: 0.89, p < 0.001) were highly associated with use of memory strategies. Subjects who were older, unemployed, more depressed, and have more mobility disability were less likely to use memory strategies.

CONCLUSIONS

Use of AT for memory is widespread and further research should be conducted on efficacy of AT. Many individuals who might be presumed to need AT for memory most (older, less educated, more disability) are least likely to report use. Healthcare providers are urged to ask about memory AT and make appropriate referrals.

Measures of physical functioning predict self-reported performance in self-care, mobility, and domestic life in ambulatory persons with multiple sclerosis

OBJECTIVE

To determine the associations between clinically measured physical functioning variables and self-reported performance in mobility, self-care, and domestic life in ambulatory persons with multiple sclerosis (MS), using the International Classification of Functioning, Disability and Health (ICF) as a framework.

DESIGN

Survey study.

SETTING

Community setting in Finland.

PARTICIPANTS

A population-based sample of 120 ambulatory persons with MS (30 men, 90 women) with mean age 45.0+/-10.8 years (range, 20-71 y), mean disease duration from symptom onset 12.3+/-8.8 years (range, 1-39 y), and mean Expanded Disability Status Scale 2.8+/-2.0 (range, 0-6.5).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The primary dependent variables were self-reported performance in self-care, mobility, and domestic life from the Functional Status Questionnaire. The physical functioning variables were drawn from the ICF activities (n=9) and body functions (n=14) categories. Age- and sex-adjusted odds ratios from multinomial logistic regression were estimated for the physical functioning variables associated with activities of daily living (ADL) performance.

RESULTS

Overall, of this cohort 31% reported difficulties or dependence in self-care, 52% in mobility, and 68% in domestic life. The most significant predictors of perceived difficulties or dependence in ADL performance were: (1) lower scores in the Box and Block Test; (2) lower Berg Balance Scale scores; (3) greater velocity moment when standing with eyes open; (4) slower ten-meter walk test times and shorter stride length at normal speed; and (5) shorter distance in the six-minute walk test.

CONCLUSIONS

Perceived difficulties and dependence were most prominent in domestic life. In particular, measures of activities predicted difficulties in ADL performance. Monitoring of physical functioning should be extended to those independent MS persons reporting difficulties in ADL performance.
