[Scale for the assessment and rating of ataxia (SARA): translation and cultural adaptation to German-speaking areas]

BACKGROUND/OBJECTIVE

The scale for the assessment and rating of ataxia (SARA) is a feasible assessment for the classification and evaluation of therapeutic interventions. In order to provide access to the SARA in German, the aim of this work was to translate the SARA into German and to adapt it according to international guidelines for German-speaking countries.

METHOD

The process involved six steps. The comprehensibility of the scale was assessed using interviews with potential users.

RESULTS

A total of nine physiotherapists and six physicians working in various clinical settings were interviewed, seven of them worked in Germany and four each in Austria and Switzerland. The interviews led to a refined version of the translation. The comprehensibility testing revealed no country-specific differences.

CONCLUSION

A German version of the SARA authorized by the co-author of the original publication, is now available. The results provide methodological insights into the translation process of observation-based standardized assessments.

Validity of assessing level walking with the 2D motion analysis software TEMPLO and reliability of 3D marker application

In gait analysis, knowledge on validity and reliability of instruments and influences caused by the examiner's performance is of crucial interest. These measurement properties are not yet known for commonly used, low-cost two-dimensional (2D) video-based systems. The purpose of this study was to assess the concurrent validity of a video-based 2D system against a three-dimensional (3D) reference standard, as well as the inter-rater reliability, and test-retest reliability of 3D marker application. Level walking was captured simultaneously by a 2D and a 3D system. Reflective markers were applied independently by three raters and repeated by one rater on a second day. We assessed the agreement between the two systems, as well as reproducibility, and inter-rater agreement of derived spatio-temporal parameters and sagittal kinematics. Nineteen healthy participants completed this study. 2D gait analysis provides a possibility to accurately assess parameters such as stride time, stride length, gait velocity, and knee RoM. Interrater and test-retest reliability of 3D gait analysis are generally acceptable, except for the parameters toe-off and pelvic RoM. This is the first study to publish measurement properties of a commercially available 2D video-based gait analysis system, which can support interpretation of gait pattern near the sagittal plane.

Group-based circuit training to improve mobility after stroke: a cross-sectional survey of German and Austrian physical therapists in outpatient settings

BACKGROUND

A contextual transferability analysis identified group-based circuit training (GCT) as an optimal intervention in German and Austrian outpatient physical therapy to improve mobility post-stroke. GCT incorporates task-oriented, high-repetitive, balance, aerobic and strength training and allows for increased therapy time without increasing personnel.

OBJECTIVE

To determine the extent to which German and Austrian physical therapists (PTs) use GCT and its components in the outpatient treatment of stroke-related mobility deficits and to identify factors associated with using GCT components.

METHODS

A cross-sectional online survey was conducted. Data were analyzed descriptively and using ordinal regression.

RESULTS

Ninety-three PTs participated. None reported using GCT moderately to frequently (4- 10/10 patients). The percentage of PTs reporting frequent use (7- 10/10 patients) of task-oriented, balance, strength, aerobic, and high-repetitive training was 45.2%, 43.0%, 26.9%, 19.4%, and 8.6%, respectively. Teaching or supervising students, time for evidence-based practice activities at work, and working in Austria was associated with using GCT components frequently.

CONCLUSION

German and Austrian PTs do not yet use GCT in outpatient physical therapy for stroke. Almost half of PTs, however, employ task-oriented training as recommended across guidelines. A detailed, theory-driven and country-specific evaluation of barriers to GCT uptake is necessary to inform implementation.

Task-Oriented Circuit Training for Mobility in Outpatient Stroke Rehabilitation in Germany and Austria: A Contextual Transferability Analysis

People with stroke cite mobility deficits as one of the most burdensome limitations. National and international stroke guidelines recommend physical therapy based on task-oriented practice, with high numbers of repetitions to improve mobility. In the outpatient setting in Germany and Austria, these principles have not yet been established. The purpose of this study was to identify an evidence-based intervention that could help reduce this research-practice gap. A stepwise approach proposed by Voigt-Radloff and colleagues and Cochrane Germany was used. First, the specific health service problem in the German and Austrian physical therapy outpatient context was identified. Second, a promising intervention was identified using a systematic search in the Cochrane Library and by grading the quality of the evidence using the Grading of Recommendations Assessment, Development and Evaluation. Finally, the transferability of the promising intervention into the local context was evaluated using predefined questions from the Cochrane guide and reports from health insurances, professional organizations, and national stroke guidelines. Task-oriented circuit training reviewed by English and colleagues was chosen. The review showed clinically important improvements in walking distance and speed. The quality of the evidence was graded high for these 2 outcomes. We identified contextual challenges for implementation at the setting level (eg, insufficient reimbursement for group therapy by insurance companies), the participant and therapist level (eg, unknown motivation for group therapy due to the established 1:1 patient-therapist ratio), and the outcome measure level (eg, lack of standardized, cross-culturally translated manuals). Although task-oriented circuit training is scientifically well established, barriers to implementation into routine care in Germany and Austria can be expected. In a next step, research using knowledge translation methodology will focus on the detailed evaluation of barriers and facilitators with relevant stakeholders.

[Translation of the evidence-based practice confidence (EPIC) scale into German and its cross-cultural adaption for Switzerland, Austria and Germany]

BACKGROUND

The Evidence-based Practice Confidence (EPIC) scale is a self-report questionnaire for health professionals. The EPIC scale was developed in Canada and is based on Bandura's self-efficacy theory. It comprises 11 statements on the organization and implementation of evidence-based practice (EBP) steps. The aim of the study was to translate the EPIC scale into German, to test its comprehensibility in German-speaking countries and to interculturally adapt the scale.

METHODS

The translation process followed international guidelines. After two independent translations into German and two independent back translations had been conducted, an expert committee discussed discrepancies in view of intercultural comprehensibility and agreed on a preliminary German version. The comprehensibility of this version was evaluated with physical therapists from Switzerland, Austria and Germany. They were recruited using purposeful sampling and interviewed via telephone using a semi-structured questionnaire (cognitive interviewing). The interviews were recorded and analyzed independently by two authors using a structured evaluation scheme. Based on these results, the final version was created. All changes were discussed with the author of the EPIC scale.

RESULTS

Sixteen physical therapists of the three German-speaking countries were interviewed. Demographic data showed a balanced distribution of country of origin, age group, qualification and years of work experience. In general, participants reported a good overall comprehensibility. However, they reported that (too) many scientific terms caused comprehension problems and that some of these terms were unknown to participants. During the intercultural adaptation attention was paid to simplify and shorten sentences and to paraphrase terms that were difficult to understand. Moreover, the instructions were expanded to address partial lack of knowledge of scientific terms.

CONCLUSION

The EPIC scale was successfully translated and interculturally adapted to the German language. The scale evaluates self-efficacy in EBP activities and could potentially be used to assess courses or be integrated into surveys. In the next step, the validity and reliability of the German scale should be established involving other health care professionals in this process.

Intrarater and Interrater Reliability of Angular Measures Using TEMPLO Two-dimensional Motion Analysis Software

OBJECTIVE

The purpose of this study was to assess the intrarater and interrater reliability of marking 2 angles with the TEMPLO software and to provide relevant information for clinical practice.

METHODS

A prospective test-retest study has been conducted. Four raters took measures on 2 days, with 2 weeks in between. Craniovertebral angle and trunk forward lean were drawn on 22 video frames using TEMPLO. Reliability was examined using intraclass correlation coefficients including standard errors of measurement and minimal detectable change values as measures of precision expressed in the unit of the test (°).

RESULTS

Intraclass correlation coefficients for intrarater and interrater reliability ranged from 0.98 to 1.00. Standard errors of measurement and minimal detectable change values ranged from 0.4° to 0.8° and 0.8° to 2.3°, respectively.

CONCLUSION

These results indicate excellent reliability for craniovertebral angle and trunk forward lean assessed with TEMPLO software. Changes exceeding 2.3° may be expected to fall outside the test's variability.

Blended learning versus traditional teaching-learning-setting: Evaluation of cognitive and affective learning outcomes for the inter-professional field of occupational medicine and prevention / Blended Learning versus traditionelles Lehr-Lernsetting: Evaluierung von kognitiven und affektiven Lernergebnissen für das interprofessionelle Arbeitsfeld Arbeitsmedizin und Prävention

Blended learning is characterised as a combination of face-to-face teaching and e-learning in terms of knowledge transfer, students’ learning activities and reduced presence at the teaching facility. The present cohort study investigated long-term effects of blended learning regarding cognitive outcomes as well as self-indicated estimates of immediate learning effects on the affective domain in the inter-professional field of occupational medicine. Physiotherapy students (bachelor degree) at FH Campus Wien – University of Applied Sciences completed the course Occupational Medicine/Prevention either in a traditional teaching-learning setting entirely taught face-to-face (control-group, n=94), or with a blended learning model (intervention-group, n=93). Long-term effects (1.5 year follow-up) on the cognitive learning outcomes were assessed according to four levels of Bloom’s learning objectives. In addition, students estimated potential benefits resulting from blended learning based on four Krathwohl’s learning objectives for the affective domain by means of a six-option Likert scale (n=282). Concerning cognitive outcomes, significant results favouring both groups were found with effect sizes from small to medium. The traditional teaching-learning setting resulted in significantly better results in the upmost aspired learning objective (analysis) at the long-term (p<0,01; r=-0,33). In contrast, the intervention group resulted in significantly better long-term results on learning objective levels 1 (knowledge) and 2 (understanding) (p=0,01; r=-0,20 and, p=0,02; r=-0,17, respectively). Hence, no general recommendation favouring either the classical setting or blending learning can be drawn regarding the cognitive domain. However, students’ self-indications on the affective domain give preference to blended learning, particularly if inter-professional teamwork is a course objective.

Clinical relevance of the effects of reach-to-grasp training using trunk restraint in individuals with hemiparesis poststroke: A systematic review

OBJECTIVE

To evaluate the evidence for, and clinical relevance of, immediate and long-term effects of trunk restraint during reach-to-grasp training poststroke on movement patterns and functional abilities within the framework of the International Classification of Functioning, Disability and Health.

DATA SOURCES

PubMed, Web of Science, CINAHL, Embase, PEDro, Cochrane Library (publication dates January 1985 to March 2015).

STUDY SELECTION

Randomized controlled trials comparing training using trunk restraint with any other exercise training.

DATA EXTRACTION

Data were extracted by one researcher and checked by two other researchers. The Cochrane Collaboration's tool for assessing risk of bias and the Physiotherapy Evidence Database scale were used by two researchers to assess study quality and risk of bias.

DATA SYNTHESIS

Eight studies met the inclusion criteria. Five studies found better recovery of movement patterns (trunk displacement, elbow extension, and/or shoulder flexion - body function/structure) at post-test in the experimental compared with the control groups. Functional abilities (activity/participation) improved more in the experimental groups in 3 studies at post-test. Long-term effects were found in one study after 4 weeks.

CONCLUSION

Trunk restraint has immediate and some long-term effects in adults with chronic stroke. However, these effects are not consistently clinically relevant when referring to minimal detectable change or minimal clinically important difference values.
