Evaluation of functional capacity after stroke as a basis for active intervention. Presentation of a modified chart for motor capacity assessment and its reliability.

For patients with cerebrovascular disease a chart for motor capacity assessment modified after that of Fugl-Meyer et al. has been developed. The chart comprises assessment of the ability to perform active movements and rapid movement changes, mobility, balance, sensation, joint pain and passive range of motion. Both the paretic and the non-paretic sides are evaluated. An internal consistency reliability test was performed, using the standardized item alpha coefficient calculated from the values of 231 patients with stroke on admission. The coefficients were between 0.84 and 0.99 for all the different parts of the chart, except for pain, for which they were somewhat lower. This confirms that the chart and its different parts have high homogeneity and that the test situations were adequate. Bilateral evaluation provides important information on the functional ability, especially when the "non-paretic" side is also impaired.

Evaluation of functional capacity after stroke as a basis for active intervention. Validation of a modified chart for motor capacity assessment.

A chart for assessing motor capacity after acute stroke modified after Fugl-Meyer et al. (3) has been constructed. Construct validity was investigated by factor analysis performed on admission values of 231 patients with acute stroke. Three factors representing upper and lower extremity function and standing leg movements, respectively, explained 90-92% of the variance of the variables. On estimation of the convergent/concurrent validity by the Spearman's rank-difference correlation method, high coefficients were found between the modified chart and the other main instruments used in the study. The predictive validity of the motor scoring on admission was significant. In addition, functional group on admission gave some information concerning what type of care the patients might need after discharge. The modified chart for assessment of motor capacity has proved to be a valid tool with a satisfactory predictive capacity for survival and the outcome of the motor function.

Attitudes of nursing staff in general medical wards towards activation of stroke patients.

The attitudes and motivation of the nursing staff towards activation of stroke patients were studies. Staff members from two experimental wards received an educational programme on stroke. Concurrently the patients on their wards received an individually adapted nursing programme with emphasis on activation. The attitudes of the nursing staff on these wards and on two identical control wards in the same hospital were examined at 3-month intervals with the help of a 24-item questionnaire. There was a significant change in attitudes, judged on a scale constructed from 14 items, among the staff of the experimental wards during a 6-month period. There were also positive changes in individual items such as attitudes to long-term care. Fewer changes were noted among the untrained auxiliaries than among the trained staff. The high rate of turnover, especially among the untrained staff, led to certain difficulties in the collection and interpretation of data. In conclusion, the educational programme and also perhaps, the other activities of the experimental wards seemed to have affected the attitude of the staff to some extent in a positive direction.

Muscle strength and balance in post-stroke patients.

Isokinetic torque of the knee and elbow during maximal extension and flexion and isometric strength of the handgrip, as well as balance and some circulatory variables, were tested in 37 patients one year after an acute stroke. Correlations with locomotion, household work and other activities of daily living (ADL) were tested. Male patients who had received special activation on the ward for up to 4 weeks after the stroke showed a significantly smaller difference in strength between the paretic and non-paretic knee at an angular velocity of 90 degrees per second than males who had received only routine activation on their ward. There was a high correlation between locomotion and the isokinetic torque of the paretic knee and also between locomotion and balance. The correlations between elbow strength and ADL functions were weaker. It was concluded that the evaluation of the isokinetic muscle torque of the knee and the balance tests are valid instruments for estimating functional capacity after a stroke.

II. Early activation in stroke: does it make a difference?

The effect of early systematic activation in daily nursing care was studied in an experimental group of patients with acute stroke. The staff had received an educational programme on stroke and its care. Sixty stroke patients were admitted to two general medical wards during a period of 9 months. Fifty-two stroke patients from two other such wards formed a control group. The functional capacity was measured by a specially constructed Activity Index (AI) at regular intervals in all patients. The functional capacity of the experimental group improved significantly with the special care in hospital up to 4 weeks after the stroke, while the change in the control group was non-significant according to the chosen level of significance. During the remainder of the 3-month study period with routine care in both groups, the two groups improved more equally. The activation programme may thus have had a stimulation effect while it was in progress.

III. One year after stroke: a follow-up of an experimental study.

The long-term effect of an early activation programme in nursing care (APN) during the first four weeks after a stroke was studied in 33 survivors one year after the stroke. Twenty-six patients formed a control group. Functional capacity was tested with an Activity Index (AI). All patients except three were interviewed concerning household work, locomotion, and psychosocial and intellectual activities before and after the stroke. There were no significant differences in functional capacity between the experimental (E) and control (C) groups one year after the stroke. In both groups AI had improved considerably compared with the values on admission. Comparison of the pre- and post-stroke performance revealed that the decrease in median scores was most prominent in household work and psychosocial functions in both groups. A long-term effect of the APN was not proved. The ADL part of the AI had a strong predictive value for one-year survival.

I. Evaluation of the functional capacity of stroke patients through an activity index.

An evaluation instrument, the Activity Index (AI), has been constructed for measuring the functional capacity of stroke patients from the acute phase of the disease onwards. The Index consists of 16 variables divided into three main parts: mental capacity, motor activity, and ADL function. The maximum score is 92. In a group of 112 stroke patients the Cronbach alpha reliability coefficient for the total AI was 0.94, indicating a high degree of homogeneity of the test. The Spearman rank correlation coefficient between the AI and the Rankin disability scale was -0.94. The results of a bivariate linear regression analysis between the values of the Activity Index on admission (about 48 hours after the stroke) and the scoring on later test occasions, grouped as dead, low score, medium score, high score, respectively, indicated the instrument's high predictive validity. The AI can be used by different categories of trained staff in clinical practice or clinical research.
