The development of a clinical practice stroke guideline for physiotherapists in The Netherlands: a systematic review of available evidence

Purpose. To develop a clinical practice guideline for the physiotherapy management of patients with stroke as support for the clinical decision-making process, especially with respect to the selection of appropriate interventions, prognostic factors and outcome measures.

Introduction. Physiotherapists have a high caseload of patients with stroke, so there is a need to identify effective evidence-based physiotherapy procedures. The availability of a guideline that includes information about prognostic factors, interventions, and outcome measures would facilitate clinical decision-making.

Method. A systematic computerized literature search was performed to identify evidence concerning the use of: (i) prognostic factors related to functional recovery; (ii) physiotherapy interventions in patients with stroke; and (iii) outcome measures to assess patients' progress in functional health. Experts, physiotherapists working in the field of stroke rehabilitation, and a multidisciplinary group of health professionals reviewed the clinical applicability and feasibility of the recommendations for clinical practice and their comments were used to compose the definitive guideline.

Results. Of 9482 relevant articles, 322 were selected. These were screened for methodological quality. Seventy-two recommendations for clinical practice were retrieved from these articles and included in the guideline: Six recommendations concerned the prediction of functional recovery of activities of daily living (ADL), including walking ability and hand/arm use; 65 recommendations concerned the choice of physiotherapy interventions; and 1 recommendation concerned the choice of outcome instrument to use. A core set of seven reliable, responsive, and valid outcome measures was established, to determine impairments and activity limitations in patients with stroke.

Conclusions. The guideline provides physiotherapists with an evidence-based instrument to assist them in their clinical decision making regarding patients with stroke. As most of the recommendations included in the guideline came from studies of patients in the post acute and chronic phase of stroke, and in general involved patients with less severe and uncomplicated stroke, more needs to be learned about the more complex cases.     

Reliability and sources of variation of the ABILHAND-Kids questionnaire in children with cerebral palsy

Purpose: To determine reliability of the ABILHAND-Kids, explore sources of variation associated with these measurement results, and generate repeatability coefficients.

Method: A reliability study with a repeated measures design was performed in an ambulatory rehabilitation care department from a rehabilitation center, and a center for special education. A physician, an occupational therapist, and parents of 27 children with spastic cerebral palsy independently rated the children’s manual capacity when performing 21 standardized tasks of the ABILHAND-Kids from video recordings twice with a three week time interval (27 first-, and 25?second video recordings available). Parents additionally rated their children’s performance based on their own perception of their child's ability to perform manual activities in everyday life, resulting in eight ratings per child.

Results: ABILHAND-Kids ratings were systematically different between observers, sessions, and rating method. Participant?×?observer interaction (66%) and residual variance (20%) contributed the most to error variance (9%). Test–retest reliability was 0.92. Repeatability coefficients (between 0.81 and 1.82 logit points) were largest for the parents’ performance-based ratings.

Conclusion: ABILHAND-Kids scores can be reliably used as a performance- and capacity-based rating method across different raters. Parents’ performance-based ratings are less reliable than their capacity-based ratings. Resulting repeatability coefficients can be used to interpret ABILHAND-Kids ratings with more confidence.

• Implications for Rehabilitation

• The ABILHAND-Kids is a valuable tool to assess a child's unimanual and bimanual upper limb activities.

• The reliability of the ABILHANDS-Kids is good across different observers as a performance- and capacity-based rating method.

• Parents' performance-based ratings are less reliable than their capacity-based ones.

• This study has generated repeatability coefficients for clinical decision making.

     

Retention of "safe" blood donors. The Retrovirus Epidemiology Donor Study

BACKGROUND: There are obvious advantages to increasing donor retention. However, for reasons of blood safety, certain donors may, in fact, be more desirable to retain than others. “Safe” donors are defined as those who provided a blood donation that was negative on all laboratory screening tests and who subsequently reported no behavioral risks in response to an anonymous survey. This study identifies the most important factors affecting the intention of “safe” donors to provide another donation. STUDY DESIGN AND METHODS: An anonymous survey asking about donation history, sexual history, injecting drug use, and recent donation experience was mailed to 50,162 randomly selected allogeneic donors (including directed donors) who gave blood from April through July or from October through December 1993 at one of the five United States blood centers participating in the Retrovirus Epidemiology Donor Study. Before mailing, questionnaires were coded to designate donors with nonreactive laboratory screening tests at their most recent donation. RESULTS: A total of 34,726 donors (69%) responded, with substantially higher response among repeat donors. According to reported intentions only, the vast majority of “safe” donors indicated a high likelihood of donating again within the next 12 months. Only 3.4 percent reported a low likelihood of donating again. A comparison of those likely to return and those unlikely to return reveals significant differences in demographics and in ratings of the donation experience. A higher proportion of those unlikely to return were first-time donors, minority-group donors, and donors with less education. The highest projected loss among “safe” donors was seen for those who gave a fair to poor assessment of their treatment by blood center staff or of their physical well-being during or after donating. CONCLUSION: These data suggest that efforts to improve donors' perceptions of their donation experience, as well as attention to the physical effects of blood donation, may aid in the retention of both repeat and first-time donors.     

The statistical efficiency for detecting sinusoidal modulation of average dot density in random figures

The average density of randomly placed dots was modulated according to a spatial sinusoid and estimates were made of the signal/noise ratio (d′) of the sensory representation of the pattern from subjects responses. This was compared with the signal/noise ratio of the targets and the results are expressed as the efficiency (F) with which the statistical information in the targets is utilized. For single-barred gratingsF can reach 50% and it decreases as the number of bars increases. For many-barred gratingsd′ is an accelerating function of modulation depth. These results can be partly interpreted in terms of a model using “and” and “or” operations to match the image with a caricature of the expected pattern that the subject holds in his mind.     

A new dimension: robotic reconstruction in plastic surgery

Background  

Robot-assisted surgery was first approved by the Federal Drug Administration in 1994. The robotic system has the advantages of three-dimensional visualization of the operating field, 7° range of motion, tremor elimination, 360°of freedom at 10-mm distance, and a comfortable, seated operating posture. The purpose of this paper is to present a new surgical tool, the robot, for use in reconstructive surgery.     

Everyday physical activity in adolescents and young adults with meningomyelocele as measured with a novel activity monitor.

We measured the extent of hypoactivity in adolescents and young adults with meningomyelocele with an activity monitor. The activity monitor is based on long-term ambulatory monitoring of signals from body-fixed accelerometers during everyday life and is aimed at the assessment of mobility-related activities. Measurements were performed during 2 consecutive weekdays in 14 patients with meningomyelocele (aged 14 to 26 years) and in 14 matched, healthy subjects. Mean duration of dynamic activities (composite measure) was less in the patients (6.5 +/- 2.3%) than in comparison subjects (12.7 +/- 4.3%, P =.001). Number of walking or wheelchair-driving periods was 122 +/- 48 in the patients and 185 +/- 65 in the comparison subjects (P =.01). Resting heart rate was higher in the patients (70 +/- 7 beats/min vs 64 +/- 5 beats/min, P =.01). Time spent with dynamic activities was correlated with ambulatory status (r(s) = 0.55, P <.05). Adolescents and young adults with meningomyelocele, particularly the nonambulators, are considerably hypoactive.
