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.

Motivational orientation of people participating in vocational rehabilitation

PURPOSE

The task of vocational rehabilitation is to support the employee's chances of continuing in working life. The study aimed to examine the motivational orientation of people participating in vocational rehabilitation and to find out what characteristics of the clients, their life situation, and their beliefs and perceptions were associated with it.

METHODS

A mail questionnaire was answered by 839 rehabilitation clients who had received an affirmative rehabilitation decision under the earnings-related pension scheme 12 months earlier (response rate 67 %). Two variables depicting motivational orientation were formed, i.e., motivation for continuing in working life and motivation for participating in vocational rehabilitation. Logistic regression analyses were applied in examining the factors associated with each motivation variable.

RESULTS

The results indicate that the two motivational orientations can be regarded as partly separate and partly overlapping constructs. The rehabilitation clients' motivational orientations were associated with their experiences and their perceptions on environmental factors and future possibilities, both those that precipitated the application for rehabilitation and those that are important in their current life situation and their perceived future possibilities.

CONCLUSIONS

In the planning of individual rehabilitation processes there is a clear need to sort out what factors may hide behind the client's weak contextual or situational motivation. In the course of the rehabilitation process, it is important to discuss these factors in order to alleviate the clients' uncertainty towards change and enhance their motivation to participate in rehabilitation and re-think their future prospects of returning to work.

When Should Physical Rehabilitation Commence after Stroke: A Systematic Review

Background

Knowing when to commence physical rehabilitation after stroke is important to ensure optimal benefit for stroke survivors and efficient health care. The aims of this review were to: determine the effects on mortality, function and complications when physical rehabilitation commences ‘early’ (within seven days of stroke); and describe the effects of early transfer to rehabilitation wards/hospitals when sustained rehabilitation is unavailable in acute stroke units.

Review summary

From 3751 potential articles we included 5 randomized controlled trials and 38 cohort studies. Meta-analysis was performed with 3 randomized controlled trials involving 159 people to investigate the effects of commencing physical rehabilitation within 24 h of stroke compared to 48 h. Commencing physical rehabilitation within 24 h trended towards greater mortality (Mantel-Haenszel odds ratio 2·58; 95% confidence interval 0·98 to 6·79, P = 0·06), with no differences in complications or health outcomes. The cohort studies provided evidence of benefits when physical rehabilitation was commenced on the day of admission ( n = 1), within 3 days of stroke ( n = 3), or ‘sooner rather than later’ (3 of 4 studies). The effect of earlier transfer to rehabilitation was reported in 32 cohort studies. In 23/26 (88%) cohort studies that accounted for age and stroke severity, results favored earlier transfer for improving post-stroke function, with no consensus on timeframes.

Conclusion

In summary, the benefits of commencing physical rehabilitation within 24 h of stroke remain unclear from the current literature. Commencing physical rehabilitation or transferring to rehabilitation services ‘early’ may provide better functional outcomes.

Discharge function and length of stay for patients with stroke are predicted by lower extremity muscle force on admission to rehabilitation

OBJECTIVE

We sought to determine the relative value of lower extremity muscle strength as a predictor of discharge function and length of stay of patients with stroke.

METHODS

We studied 72 patients undergoing inpatient rehabilitation after a stroke and documented their outcome using length of stay and function [as measured by the Functional Independence Measure (FIM) at discharge].

RESULTS

Knee-extension force and the total force of four lower extremity muscle actions (hip flexion, knee extension, knee flexion, and ankle dorsiflexion) were correlated significantly with discharge FIM and length of stay. The correlations involving the actions of the weaker side were higher. Admission FIM was also correlated significantly with discharge FIM and length of stay. Previous stroke and age were correlated significantly with discharge FIM but not length of stay. The set of variables offering the best explanation of discharge FIM (R = 0.867) was admission FIM, admission FIM squared, age, and total force of the weaker side. The set of variables offering the best explanation of length of stay (R = 0.812) was knee-extension force of the weaker side squared, admission FIM, admission FIM squared, and age.

CONCLUSIONS

Lower extremity muscle force of the weaker side on admission has value as a predictor of function at discharge and length of stay for patients with stroke admitted to inpatient rehabilitation. Muscle force, therefore, is a reasonable target of measurement and treatment. Knowledge of muscle force on admission can assist clinicians, patients, families, and others to anticipate patient outcomes after rehabilitation.

Predicting discharge destination for patients with severe motor stroke: important functional tasks

Many patients with severe stroke are capable of returning to the community after receiving rehabilitation services. The purpose of this study was to describe outcomes of patients with stroke in FIM-FRG STR1, a classification based on the Functional Independence Measure, and identify important functional tasks associated with discharge to home. FIM-FRG STR1 is one of nine subpopulations of stroke that have been identified based on motor/cognitive FIM subscale score and age. We reviewed the program evaluation data of 259 cases of stroke from 1993 to 1996. We performed a descriptive analysis of the data and a logistic regression analysis to determine which tasks measured by the FIM were associated with discharge destination, a key indicator of rehabilitation success. We found that three admission FIM variables (bladder management, toilet transfers, memory) and three discharge FIM variables (upper body dressing, bed/chair transfers, comprehension) were associated with discharge destination with up to 75% accuracy. The implications of these findings are discussed.

Predicting motor recovery of the upper limb after stroke rehabilitation: value of a clinical examination

BACKGROUND AND PURPOSE

Only a few studies have been conducted to predict motor recovery of the arm after stroke. The aims of this study were to identify which clinical variables, assessed at different points in time, were predictive of motor recovery, and to construct useful regression equations.

METHOD

One hundred consecutive stroke patients who had an obvious motor deficit of the upper limb were evaluated on entry to the study (two to five weeks post-stroke) and at two, six and 12 months after stroke. The Brunnström-Fugl-Meyer test was used as the outcome measure. Predictors included demographic data, overall disability, clinical neurological features, neuropsychological factors and secondary shoulder complications.

RESULTS

In multiple regression analyses, motor performance was invariably retained as the predictive factor with the highest R-square. Other significant predictive variables were overall disability, muscle tone, proprioception and hemi-inattention. Between 53% and 89% of the total amount of variance was accounted for in all selected models. The accuracy of prediction from clinical measurement in the acute phase diminished as the time span of measurement of outcome increased. Similarly, assessment of the variables at two and six months, rather than in the acute stage, resulted in a considerable improvement in the percentage variance explained at 12 months. The highest accuracy was obtained when predictions were made step-by-step in time.

CONCLUSIONS

It is possible to predict motor recovery of the upper limb accurately through the use of a few clinical measures. Predictive equations are proposed, the use of which are practicable in both clinical practice and research.
