Reacquisition of dressing skills after stroke

Errorless learning and assistive technology did not improve the negative prognosis for severe dressing impairment after stroke if persisting for two weeks: A randomized controlled trial

Following severe cerebrovascular accidents, patients are often unable to dress themselves. Little is known about the persistence and treatment of this impairment. Study 1 followed 23 patients who were (1) completely dependent on others for help with dressing (2) for two weeks continually until their discharge from the rehabilitation unit. Study 2, a randomized controlled trial of 24 patients, examined the effects of errorless learning and RehaGoal App-based dressing practice on recovery in dressing ability-impaired patients who also experienced visuospatial neglect and/or apraxia. The control and intervention groups both underwent a standard therapy in the rehab unit; the intervention group additionally received dressing training (seven sessions of 45 min). The primary outcome measure was the score on an adapted version of the Nottingham Stroke Dressing Assessment; secondary outcome measures were the Barthel Index and Functional Independence Measure. Less than one-third of the patients in Study1, showed improvement. In Study 2, the intervention produced no specific effect on patients' dressing ability. However, apraxia and neglect predicted improvement for both groups. If patients depend completely on assistance for dressing for two weeks, prospects for recovery are limited. Future studies should include additional intervention sessions and incorporate treatments for neglect or apraxia.

Occupational therapy for cognitive impairment in stroke patients

BACKGROUND

Cognitive impairment is a frequent consequence of stroke and can impact on a person's ability to perform everyday activities. Occupational therapists use a range of interventions when working with people who have cognitive impairment poststroke. This is an update of a Cochrane Review published in 2010.

OBJECTIVES

To assess the impact of occupational therapy on activities of daily living (ADL), both basic and instrumental, global cognitive function, and specific cognitive abilities in people who have cognitive impairment following a stroke.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register, CENTRAL, MEDLINE, Embase, four other databases (all last searched September 2020), trial registries, and reference lists.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials that evaluated an intervention for adults with clinically defined stroke and confirmed cognitive impairment. The intervention needed either to be provided by an occupational therapist or considered within the scope of occupational therapy practice as defined in the review. We excluded studies focusing on apraxia or perceptual impairments or virtual reality interventions as these are covered by other Cochrane Reviews. The primary outcome was basic activities of daily living (BADL) such as dressing, feeding, and bathing. Secondary outcomes were instrumental ADL (IADL) (e.g. shopping and meal preparation), community integration and participation, global cognitive function and specific cognitive abilities (including attention, memory, executive function, or a combination of these), and subdomains of these abilities. We included both observed and self-reported outcome measures.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies that met the inclusion criteria, extracted data, and assessed the certainty of the evidence. A third review author moderated disagreements if consensus was not reached. We contacted trial authors for additional information and data, where available. We assessed the certainty of key outcomes using GRADE.  MAIN RESULTS: We included 24 trials from 11 countries involving 1142 (analysed) participants (two weeks to eight years since stroke onset). This update includes 23 new trials in addition to the one study included in the previous version. Most were parallel randomised controlled trials except for one cross-over trial and one with a two-by-two factorial design. Most studies had sample sizes under 50 participants. Twenty studies involved a remediation approach to cognitive rehabilitation, particularly using computer-based interventions. The other four involved a compensatory and adaptive approach. The length of interventions ranged from 10 days to 18 weeks, with a mean total length of 19 hours. Control groups mostly received usual rehabilitation or occupational therapy care, with a few receiving an attention control that was comparable to usual care; two had no intervention (i.e. a waiting list). Apart from high risk of performance bias for all but one of the studies, the risk of bias for other aspects was mostly low or unclear.  For the primary outcome of BADL, meta-analysis found a small effect on completion of the intervention with a mean difference (MD) of 2.26 on the Functional Independence Measure (FIM) (95% confidence interval (CI) 0.17 to 4.22; P = 0.03, I2 = 0%; 6 studies, 336 participants; low-certainty evidence). Therefore, on average, BADL improved by 2.26 points on the FIM that ranges from 18 (total assist) to 126 (complete independence). On follow-up, there was insufficient evidence of an effect at three months (MD 10.00, 95% CI -0.54 to 20.55; P = 0.06, I2 = 53%; 2 studies, 73 participants; low-certainty evidence), but evidence of an effect at six months (MD 11.38, 95% CI 1.62 to 21.14, I2 = 12%; 2 studies, 73 participants; low-certainty evidence). These differences are below 22 points which is the established minimal clinically important difference (MCID) for the FIM for people with stroke. For IADL, the evidence is very uncertain about an effect (standardised mean difference (SMD) 0.94, 95% CI 0.41 to 1.47; P = 0.0005, I2 = 98%; 2 studies, 88 participants). For community integration, we found insufficient evidence of an effect (SMD 0.09, 95% CI -0.35 to 0.54; P = 0.68, I2 = 0%; 2 studies, 78 participants). There was an improvement of clinical importance in global cognitive functional performance after the intervention (SMD 0.35, 95% CI 0.16 to 0.54; P = 0.0004, I2 = 0%; 9 studies, 432 participants; low-certainty evidence), equating to 1.63 points on the Montreal Cognitive Assessment (MoCA) (95% CI 0.75 to 2.52), which exceeds the anchor-based MCID of the MoCA for stroke rehabilitation patients of 1.22. We found some effect for attention overall (SMD -0.31, 95% CI -0.47 to -0.15; P = 0.0002, I2 = 20%; 13 studies, 620 participants; low-certainty evidence), equating to a difference of 17.31 seconds (95% CI 8.38 to 26.24), and for executive functional performance overall (SMD 0.49, 95% CI 0.31 to 0.66; P < 0.00001, I2 = 74%; 11 studies, 550 participants; very low-certainty evidence), equating to 1.41 points on the Frontal Assessment Battery (range: 0-18). Of the cognitive subdomains, we found evidence of effect of possible clinical importance, immediately after intervention, for sustained visual attention (moderate certainty) equating to 15.63 seconds, for working memory (low certainty) equating to 59.9 seconds, and thinking flexibly (low certainty), compared to control.

AUTHORS' CONCLUSIONS

The effectiveness of occupational therapy for cognitive impairment poststroke remains unclear. Occupational therapy may result in little to no clinical difference in BADL immediately after intervention and at three and six months' follow-up. Occupational therapy may slightly improve global cognitive performance of a clinically important difference immediately after intervention, likely improves sustained visual attention slightly, and may slightly increase working memory and flexible thinking after intervention. There is evidence of low or very low certainty or insufficient evidence for effect on other cognitive domains, IADL, and community integration and participation.  Given the low certainty of much of the evidence in our review, more research is needed to support or refute the effectiveness of occupational therapy for cognitive impairment after stroke. Future trials need improved methodology to address issues including risk of bias and to better report the outcome measures and interventions used.

Effect of residual lower-extremity function on strategies and execution time for raising and lowering trousers in patients with hemiparetic stroke: a cross-sectional study

Background/aims

There are no established methods for patients with hemiparetic stroke to practice the raising and lowering of trousers. The aim of this study was to investigate the use of different strategies by patients with hemiparetic stroke for lowering and raising trousers by using the non-paretic upper limb in the standing position, based on residual motor function in the paretic lower limb.

Methods

A total of 28 patients with hemiparetic stroke were included in the study (n=10, 12, and 6 with lower-limb Brunnstrom stages III, IV and V respectively). Endpoints were execution time and frequency of changing the manipulation region.

Results

Lower-limb Brunnstrom stages III, IV and V were associated with execution times of 24.1 ± 11.1, 18.1 ± 6.5 and 16.9 ± 9.6 seconds respectively, and the mean frequency of manipulation of trousers on the posterior paretic side was significantly lower than those of the anterior paretic, anterior non-paretic, and posterior non-paretic sides in all patients (P<0.05).

Conclusions

Motor function of the paretic lower limb did not affect the strategies used for lowering and raising trousers with the non-paretic upper limb. Manipulation of trousers on the posterior paretic side was especially difficult.

An audit of dressing practice by occupational therapists in acute stroke settings in England

Introduction

Dressing independence is commonly affected after stroke, with clinical guidelines recommending that dressing practice should routinely be provided for those with dressing difficulties. The aim of this study was to update the literature on current practice in the treatment of dressing problems in stroke rehabilitation units.

Method

A questionnaire survey of occupational therapists experienced in stroke care was sent to 157 stroke units in England.

Results

Responses were received from 70 stroke units. Frequency and duration of dressing practice varied substantially between units, with respondents typically providing dressing practice for six to 10 patients per week and spending 30 to 45 minutes per treatment session. Only 17 respondents (24.3%) stated that they regularly used standardised assessments of dressing ability. The functional approach was used more widely than the remedial approach. Service priorities, working environment and limitations of time and staffing were reported to influence dressing practice.

Conclusion

There is widespread variability in dressing practice. There is a lack of use of standardised dressing assessments, and therapists’ rationale for their choice of approach is unclear.

Dressing after a Stroke: A Survey of Current Occupational Therapy Practice

The objective of this study was to determine occupational therapists' beliefs about the influence of cognitive impairment on dressing difficulties and to ascertain current practice when treating dressing problems. The study design was a questionnaire survey of occupational therapists experienced in stroke care who treated patients with dressing difficulties.

Out of 137 questionnaires sent, 76 (55.5%) were returned. The frequency of dressing practice provided by the occupational therapists ranged from two to four times a week. Only 43% of the therapists used standardised assessments and the most common one used was the Rivermead Perceptual Assessment Battery. Apraxia was reported by 76% of the therapists as influencing a patient's ability to dress, neglect by 71 % and memory problems by 63%. Seventy-six per cent of the therapists reported that orientating clothing and relating it to body parts was a major dressing difficulty. Other dressing difficulties reported were sequencing by 56% and failing to dress the affected side by 34%. Ninety-eight per cent of the therapists spent time providing the practice of specific functional skills on a repetitive basis; however, 60% continued to use table-top tasks aimed at targeting a particular cognitive impairment.

The majority of the therapists felt that cognitive impairment was a major reason for dressing difficulties in stroke patients. With the exception of one, all the therapists provided repetitive practice on dressing tasks and over half continued to use table-top tasks. The evidence to support the types of treatment used by occupational therapists remains controversial. Further research into this area is required.

Dressing Ability after Stroke: A Review of the Literature

Despite regular occupational therapy, many stroke patients remain dependent for dressing. The latter half of the 20th century has witnessed considerable debate in the literature as to the underlying deficits that influence a person's ability to relearn to dress. This paper critiques the relationship between cognitive and physical skills and recovery in dressing. The implications for occupational therapy are discussed.

Evaluation of dressing practice for stroke patients after discharge from hospital: a crossover design study

Objective: To determine whether giving dressing practice to patients at home with unresolved dressing problems following stroke reduces the problems.

Design: A randomized crossover study design was used, randomly allocating patients to receive no intervention for three months followed by three months' treatment, or the reverse.

Setting: All patients were at home, and treatment was given in the home.

Subjects: Patients at home with problems in dressing six months after acute stroke, having been discharged from hospital.

Intervention: A senior occupational therapist gave regular dressing practice to patients with their families. Specific techniques depended upon the problem.

Outcome measures: An independent assessor used the Nottingham Stroke Dressing Assessment, the Rivermead ADL, self-care section, and the Notting ham Health Profile to measure outcome.

Results: Fifteen patients were included in each group. Both groups showed statistically significant improvement during the treatment phase (Wilcoxon matched pairs test: z = 2.47, p = 0.01; z = 3.01, p = 0.002). Neither group showed any change during the non-treatment phase. Patients who received treatment in the first three months maintained their improvement (z= 0.90, p = 0.36).

Conclusion: Dressing practice given at home to patients who have residual problems in dressing six months after acute stroke leads to a sustained reduction in their problems.

The effect of personal care training at a medical department: a study in occupational therapy

The effectiveness of ADL (activities of daily living) training was evaluated in 26 older adult patients who received medical care and nursing on seven wards at a Swedish medical department. The patients were selected consecutively following their referral to the occupational therapists and were assigned alternately to an experimental group ( n=14) who underwent ADL training 2-13 times during an average of 12 days, and a control group ( n=12). The patients' level of dependence in ADL was assessed using the Klein-Bell ADL scale before and after the ADL training (experimental group) and at corresponding points for the control group. A significant difference between the experimental group and the control was demonstrated in the ADL area Bathing/Hygiene (F(1,22) = 8.29; p = 0.009). There were strong tendencies towards significant differences between the groups in the variables 'mobility' (F(1,22) = 3.69; p = 0.07) and 'Eating' (F(1,22) = 4.05; p = 0.06).

Approaches for improving the toileting problems of hemiplegic stroke patients with poor standing balance

[Purpose] Our objective was to evaluate the residual dynamic and static functionality in the sitting position of hemiplegic stroke patients who require help to pull their lower garments up and down during toileting. [Subjects and Methods] The subjects were 11 hemiplegic patients. We gathered data on the patients’ motor paralysis, sensory capacity, lower extremity muscle strength, trunk control, ability to roll and sit up from a lying position, sitting balance, and ability to pull the lower garments up and down. We then compared 2 groups: those able to pull the lower garments up and down independently while standing (the “independent group”), and those who were unable to do so (the “non-independent group”). [Results] Though the non-independent group had severely and significantly reduced trunk control and abilities as a whole, there was no significant difference from the independent group in static and dynamic sitting balance. [Conclusion] We conclude that, to enable hemiplegic patients with poor standing balance to pull their lower garments up and down, it is necessary to do these maneuvers in a sitting, rather than a standing, position, or to develop garments that are easier to put on and take off.

Improved underpants to reduce toileting problems in patients with poor standing balance

[Purpose] We developed and assessed improved underpants allowing patients to easily and completely open the crotch by pulling upward a string on the back of the underpants while seated. [Subjects and Methods] Healthy subjects tested commercial open-crotch underpants for disabled people and our improved open-crotch underpants by opening the crotch while seated. Measurement parameters included the percentage of crotch opening and the degree of genital or anal exposure before and after opening the crotch, as well as fit. The percentage of crotch opening and the degree of genital or anal exposure were recorded with a digital camera, and fit was determined with a visual analog scale. The measurements for both types of underpants were then compared. [Results] The commercial underpants for disabled people allowed opening of the crotch while seated, but the exposure of the genital and anal areas was insufficient to allow waste elimination. The improved underpants allowed sufficient opening of the crotch while seated and adequately exposed the genital and anal areas. The fit score of the improved underpants was significantly better than that of the commercial underpants. [Conclusion] The improved open-crotch underpants may allow for more effective opening of the crotch while seated than commercial open-crotch underpants for disabled people.

Reliability and validity of the upper-body dressing scale in Japanese patients with vascular dementia with hemiparesis

The purpose of this study was to examine the reliability and validity of the Upper-body Dressing Scale (UBDS) for buttoned shirt dressing, which evaluates the learning process of new component actions of upper-body dressing in patients diagnosed with dementia and hemiparesis. This was a preliminary correlational study of concurrent validity and reliability in which 10 vascular dementia patients with hemiparesis were enrolled and assessed repeatedly by six occupational therapists by means of the UBDS and the dressing item of the Functional Independence Measure (FIM). Intraclass correlation coefficient was 0.97 for intra-rater reliability and 0.99 for inter-rater reliability. The level of correlation between UBDS score and FIM dressing item scores was -0.93. UBDS scores for paralytic hand passed into the sleeve and sleeve pulled up beyond the shoulder joint were worse than the scores for the other components of the task. The UBDS has good reliability and validity for vascular dementia patients with hemiparesis. Further research is needed to investigate the relation between UBDS score and the effect of intervention and to clarify sensitivity or responsiveness of the scale to clinical change.

Cognitive rehabilitation for executive dysfunction in adults with stroke or other adult non-progressive acquired brain damage

BACKGROUND

Executive functions are the controlling mechanisms of the brain and include the processes of planning, initiation, organisation, inhibition, problem solving, self monitoring and error correction. They are essential for goal-oriented behaviour and responding to new and novel situations. A high number of people with acquired brain injury, including around 75% of stroke survivors, will experience executive dysfunction. Executive dysfunction reduces capacity to regain independence in activities of daily living (ADL), particularly when alternative movement strategies are necessary to compensate for limb weakness. Improving executive function may lead to increased independence with ADL. There are various cognitive rehabilitation strategies for training executive function used within clinical practice and it is necessary to determine the effectiveness of these interventions.

OBJECTIVES

To determine the effects of cognitive rehabilitation on executive dysfunction for adults with stroke or other non-progressive acquired brain injuries.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register (August 2012), the Cochrane Central Register of Controlled Trials (The Cochrane Library, August 2012), MEDLINE (1950 to August 2012), EMBASE (1980 to August 2012), CINAHL (1982 to August 2012), PsycINFO (1806 to August 2012), AMED (1985 to August 2012) and 11 additional databases. We also searched reference lists and trials registers, handsearched journals and conference proceedings, and contacted experts.

SELECTION CRITERIA

We included randomised trials in adults after non-progressive acquired brain injury, where the intervention was specifically targeted at improving cognition including separable executive function data (restorative interventions), where the intervention was aimed at training participants in methods to compensate for lost executive function (compensative interventions) or where the intervention involved the training in the use of an adaptive technique for improving independence with ADL (adaptive interventions). The primary outcome was global executive function and the secondary outcomes were specific components of executive function, working memory, ADL, extended ADL, quality of life and participation in vocational activities. We included studies in which the comparison intervention was no treatment, a placebo intervention (i.e. a rehabilitation intervention that should not impact on executive function), standard care or another cognitive rehabilitation intervention.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened abstracts, extracted data and appraised trials. We undertook an assessment of methodological quality for allocation concealment, blinding of outcome assessors, method of dealing with missing data and other potential sources of bias.

MAIN RESULTS

Nineteen studies (907 participants) met the inclusion criteria for this review. We included 13 studies (770 participants) in meta-analyses (417 traumatic brain injury, 304 stroke, 49 other acquired brain injury) reducing to 660 participants once non-included intervention groups were removed from three and four group studies. We were unable to obtain data from the remaining six studies. Three studies (134 participants) compared cognitive rehabilitation with sensorimotor therapy. None reported our primary outcome; data from one study was available relating to secondary outcomes including concept formation and ADL. Six studies (333 participants) compared cognitive rehabilitation with no treatment or placebo. None reported our primary outcome; data from four studies demonstrated no statistically significant effect of cognitive rehabilitation on secondary outcomes. Ten studies (448 participants) compared two different cognitive rehabilitation approaches. Two studies (82 participants) reported the primary outcome; no statistically significant effect was found. Data from eight studies demonstrated no statistically significant effect on the secondary outcomes. We explored the effect of restorative interventions (10 studies, 468 participants) and compensative interventions (four studies, 128 participants) and found no statistically significant effect compared with other interventions.

AUTHORS' CONCLUSIONS

We identified insufficient high-quality evidence to reach any generalised conclusions about the effect of cognitive rehabilitation on executive function, or other secondary outcome measures. Further high-quality research comparing cognitive rehabilitation with no intervention, placebo or sensorimotor interventions is recommended.

Transfer of training between distinct motor tasks after stroke: implications for task-specific approaches to upper-extremity neurorehabilitation

BACKGROUND

Although task-specific training is emerging as a viable approach for recovering motor function after stroke, there is little evidence for whether the effects of such training transfer to other functional motor tasks not directly practiced in therapy.

OBJECTIVE

The purpose of the current study was to test whether training on one motor task in individuals with chronic hemiparesis poststroke would transfer to untrained tasks that were either spatiotemporally similar or different.

METHODS

In all, 11 participants with chronic mild to moderate hemiparesis following stroke completed 5 days of supervised massed practice of a feeding task with their affected side. Performance on the feeding task, along with 2 other untrained functional upper-extremity motor tasks (sorting, dressing) was assessed before and after training.

RESULTS

Performance of all 3 tasks improved significantly after training exclusively on 1 motor task. The amount of improvement in the untrained tasks was comparable and was not dependent on the degree of similarity to the trained task.

CONCLUSIONS

Because the number and type of tasks that can be practiced are often limited within standard stroke rehabilitation, results from this study will be useful for designing task-specific training plans to maximize therapy benefits.

Using dual tasks to test immediate transfer of training between naturalistic movements: a proof-of-principle study

Theories of motor learning predict that training a movement reduces the amount of attention needed for its performance (i.e., more automatic). If training one movement transfers, then the amount of attention needed for performing a second movement should also be reduced, as measured under dual task conditions. The authors' purpose was to test whether dual task paradigms are feasible for detecting transfer of training between two naturalistic movements. Immediately following motor training, subjects improved performance of a second untrained movement under single and dual task conditions. Subjects with no training did not. Improved performance in the untrained movement was likely due to transfer, and suggests that dual tasks may be feasible for detecting transfer between naturalistic actions.

The Influence of Hand Use on Dressing Outcome in Cognitively Impaired Stroke Survivors

Introduction:

The daily task of dressing oneself requires multiple complex skills, which are often taken for granted by those free from ill-health or disability. Independence in dressing allows an individual to maintain a sense of dignity and choice over his or her appearance. Occupational therapy aims to restore independent functional performance in daily activities. Dressing independence requires both physical and cognitive skills. For survivors of stroke, impairment of such skills can pose great difficulty to their dressing performance.

Method:

The aim of this study was to examine the effect of arm paresis and cognitive impairment on upper body dressing ability using a cognitively impaired cohort of stroke participants (n = 70), and to explore the importance of bimanual activity when dressing in the presence of cognitive impairment. Dressing ability was assessed at baseline and immediately following a 6-week period of dressing practice with an occupational therapist.

Results:

Thirty-six participants were able to use a bimanual dressing method at baseline. The chi-square test for independence indicated a strong association between dressing method (bimanual or unimanual) and independence in upper body dressing, p<0.001. The dressing success of the bimanual group was significantly greater than that of the unimanual group at both assessment time points.

Conclusion:

Cognitively impaired stroke survivors do perform better at upper body dressing when they are able to use both hands as compared with one, but those with arm paresis preventing bimanual activity may still improve their dressing performance significantly with practice.

The DRESS trial: a feasibility randomized controlled trial of a neuropsychological approach to dressing therapy for stroke inpatients

OBJECTIVE

To investigate two approaches to treating patients with persistent dressing problems and cognitive difficulties following stroke.

DESIGN

Pilot randomized controlled trial.

SETTING

Inpatient stroke rehabilitation service.

SUBJECTS

Seventy consecutive stroke patients with persistent dressing problems and accompanying cognitive difficulties at two weeks after their stroke.

INTERVENTIONS

Patients were randomly allocated to six weeks of either a systematic neuropsychological approach, based on analysis of dressing problems and further cognitive testing, or to the control group who received conventional (functional) dressing practice. Both groups received treatment three times a week in accordance with two separately prepared manuals.

MAIN MEASURES

Nottingham Stroke Dressing Assessment (NSDA), Line Cancellation, 10-hole peg transfer test, Object Decision, Gesture Imitation. Patients were assessed at six weeks after randomization by an independent assessor masked to group allocation.

RESULTS

Both neuropsychological and functional groups improved performance on the NSDA over the treatment period (31% and 22%, respectively) but there was no significant difference between groups at six weeks. However, the neuropsychological group showed a significantly greater improvement on a line cancellation test of visual neglect (t(62) = 2.1, P < 0.05) and a planned subanalysis for those with right hemisphere damage showed a trend towards better dressing outcome (P = 0.07, one-tailed).

CONCLUSIONS

Results demonstrate the potential benefits of a systematic neuropsychological approach to dressing therapy, particularly for patients with right hemisphere damage. This study suggests the need for a phase III study evaluating the efficacy of a systematic neuropsychological approach in treating dressing difficulties, targeting patients with right hemisphere stroke and visuospatial impairments.

An Interrater Reliability Study of the Nottingham Stroke Dressing Assessment

Introduction:

Dressing problems after stroke are common. There is therefore a need to establish the psychometric properties of appropriate dressing outcome measures for use in clinical practice and research. The Nottingham Stroke Dressing Assessment (NSDA) is a validated assessment of post-stroke dressing ability. This study investigated the interrater reliability of the NSDA and the accompanying dressing error analysis form.

Method:

Twenty patients with persistent dressing difficulties at 2 weeks post-stroke were recruited to the study. Two research occupational therapists and one clinical occupational therapist acted as raters. They observed all 20 patients during dressing and independently completed the NSDA and error analysis form without discussion. A kappa (κ) test was performed to assess the level of agreement between the three raters on each dressing item assessed.

Results:

Of the 44 items tested, there was excellent agreement (κ > 0.75) on 29 items, good agreement (κ>0.6) on 8 items, fair agreement (κ>0.4) on 5 items and poor agreement (κ <0.4) on 2 items. The intraclass correlation coefficient between the three raters' final percentage score was 0.988, representing excellent agreement. The error analysis form also proved to have interrater agreement.

Conclusion:

The NSDA and error analysis form can be considered to have psychometrically proven interrater reliability.

Normal Movement and Functional Approaches to Rehabilitate Lower Limb Dressing following Stroke: A Pilot Randomised Controlled Trial

Dressing difficulties are common following stroke. However, specific interventions lack evidence. This pilot single-blind randomised controlled trial investigated normal movement and functional approaches to rehabilitate lower limb dressing, given to four eligible stroke inpatients. The Nottingham Stroke Dressing Assessment, Rivermead Motor Assessment and Canadian Occupational Performance Measure were taken at baseline, discharge and 8 weeks. The small sample lacked power. Preliminary results indicated that while all patients improved with occupational therapy, approaches may differ in rates of motor recovery, independence and treatment duration. A total sample of 30 is required for more conclusive research to inform lower limb dressing interventions.

Predicting Recovery of Upper-Body Dressing Ability After Stroke

OBJECTIVE

To identify predictors of the recovery of independent dressing ability after stroke.

DESIGN

Prospective cohort study.

SETTING

Rehabilitation unit at a university hospital.

PARTICIPANTS

Sixty-three consecutive stroke patients were enrolled in the study. Twelve patients were not able to complete the study because they were discharged or transferred to another hospital before study completion.

INTERVENTION

Fifty-one patients underwent and completed 15 days of dressing training based on the time-delay method, which included the 10 component actions of upper-body dressing and 4 cues given by therapists.

MAIN OUTCOME MEASURES

The dressing item of the FIM instrument, Brunnstrom motor recovery stages, presence or absence of deep and tactile sensation, Rey-Osterrieth complex figure test, Kohs block design test, body image test, Weintraub cancellation task, and presence or absence of the visual extinction phenomenon and the motor impersistence phenomenon.

RESULTS

The FIM upper-body dressing item score and the cancellation task score at the start of training were significantly better in patients who achieved independence in dressing within 15 training days than in patients who did not (P < .05). The motor impersistence phenomenon was found less frequently among patients who achieved independence in upper-body dressing than among patients who did not (P < .05). However, logistic regression analysis showed that only the FIM score for upper-body dressing on the first day of training was a significant independent predictor of dressing ability at the end of training (odds ratio, 4.33; 95% confidence interval, 1.51-12.37). The receiver operating characteristic curve indicated that a cutoff score of 3 would provide the best balance between sensitivity and specificity for the FIM upper-body dressing item. The positive predictive value of this cutoff score was .90, and the negative predictive value was .70.

CONCLUSIONS

Our findings indicate that the FIM upper-body dressing score on the first day of dressing training is an independent predictor of recovery of upper-body dressing ability after stroke.
