- OBJECTIVE: We sought to examine the reliability and validity of the European Brain Injury Questionnaire as an evaluation tool in a stroke population by applying the Rasch methodology.METHODS: The European Brain Injury Questionnaire was distributed to 54 patients with stroke and 36 next of kin at discharge from the rehabilitation ward and at a 1-year follow-up. Rasch analysis was used for evaluating the psychometric characteristic and the quality of the measures produced with focus on reliability and validity. The reliability was determined by the separation. The construct validity was determined by examining the hierarchy of the tasks and by evaluating the fit of individual tasks to the latent construct. Analyses of differences across occasions, and across patients and next of kin, were made to examine the stability of the instrument.RESULTS: The reliability was good as the instrument met the criteria for separation. Two items at discharge and 5 items at 1-year follow-up were misfits. If not more than 5% of the items fail to fit the Rasch model the instrument can be considered unidimensional, which in this case only concerned the 1-year follow-up. The instrument was stable over time and across patients and next of kin.CONCLUSION: With some alterations the European Brain Injury Questionnaire seems to be a useful instrument in clinical practice and research, and a help to capture the social, emotional, and cognitive impacts of a stroke.

- Today's medical treatment of patients with end-stage renal failure has increased their opportunities for an active lifestyle. The aim of this study was to describe the muscle performance, level of physical activity, independence in activities of daily living and quality of life in patients treated with chronic peritoneal dialysis.The study investigated 33 patients (30-81 years old) treated with chronic peritoneal dialysis. The results were compared with an age-matched healthy reference group. Muscle mass was determined by measuring total body potassium, while maximal grip strength was measured with an electric force transducer. The ability to perform heel-lifts, walking speed and level of physical activity were also assessed, along with the extent to which patients were independent in activities of daily living (ADL) and satisfied with their health.Total body potassium was 97 +/- 11.6% of normal and correlated positively with the maximal grip strength (r = 0.658, p < 0.0002) and the maximal walking speed (r = 0.558, p < 0.0027). Maximal grip strength was 70% of the reference, the ability to perform heel-lifts was 49% of the reference, the walking speed was 85% the reference and the level of physical activity was 56% of expected. The patients were independent in ADL to a great extent and 52% of the patients were satisfied with their health.The peritoneal dialysis patients had a relatively good quality of life and were largely independent in ADL Further studies are needed to investigate whether it is possible to improve muscle performance and the level of physical activity with exercise and muscle training in these patients.

Virtual reality and haptics as a training device for movement rehabilitation after stroke: a single-case study
- 2004
-
In: Arch Phys Med Rehabil. - : Elsevier BV. ; 85:8, s. 1247-50
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: To investigate whether training in a virtual environment with a haptic device will improve motor function in the left hemiparetic arm of a stroke subject. DESIGN: Single case, A-B-A design. SETTING: University hospital research laboratory. PARTICIPANT: A man in his late fifties (right handed), with a right-hemisphere lesion that caused a deficit in the left upper extremity. INTERVENTION: The subject trained with a 3-dimensional computer game during a 4-week period that consisted of twelve 90-minute sessions. MAIN OUTCOME MEASURES: Three tests (Purdue pegboard test, dynamometer hand-grip strength, upper-extremity test) and a subjective interview were used to evaluate motor performance. RESULTS: Improvements were found in fine manual dexterity, grip force, and motor control of the affected upper extremity. The subject reported that there was a change in his day-to-day use of the upper extremity and that he was able to use it in activities that were previously impossible for him. CONCLUSIONS: Training with virtual reality and haptics can promote motor rehabilitation.

Virtual Reality in Stroke Rehabilitation with the assistance of Haptics and Telemedicine
- 2002

In: Proceedings of The 4th International Conference on Disability, Virtual Reality and Associated Technologies.

Conference paper (peer-reviewed)abstract
- A 3D-computer game was used as a training utility to promote motor relearning on a telemedicine platform in a laboratory setting. The subject suffered from a left arm paresis. He was evaluated before and after treatment with a specific hand function task, a standardized grip force measure test and an upper extremity task. Grip force, endurance and the movement pattern of the upper extremity improved after the treatment. The telemedicine platform allows the professional to record and evaluate progress. The findings implicate that training with Virtual Reality and Haptics can promote motor rehabilitation

Hydrotherapy--a new approach to improve function in the older patient with chronic heart failure
- 2003
-
In: Eur J Heart Fail. ; 5:4, s. 527-35
-
Journal article (peer-reviewed)abstract
- AIMS: Hydrotherapy, i.e. exercise in warm water, as a rehabilitation program has been considered potentially dangerous in patients with chronic heart failure (CHF) due to the increased venous return caused by the hydrostatic pressure. However, hydrotherapy has advantages compared to conventional training. We studied the applicability of an exercise programme in a temperature-controlled swimming pool, with specific reference to exercise capacity, muscle function, quality of life and safety. METHODS AND RESULTS: Twenty-five patients with CHF (NYHA II-III, age 72.1+/-6.1) were randomised into either 8 weeks of hydrotherapy (n=15), or into a control group (n=10). The training program was well tolerated with no adverse events. Patients in the hydrotherapy group improved their maximal exercise capacity (+6.5 vs.-5.9 W, P=0.001), isometric endurance in knee extension (+4 vs.-9 s, P=0.01) together with an improvement in the performance of heel-lift (+4 vs. -3 n.o., P=<0.01), shoulder abduction (+12 vs. -8 s, P=0.01) and shoulder flexion (+6 vs. +4, P=0.01) in comparison to patients in the control group. CONCLUSION: Physical training in warm water was well tolerated and seems to improve exercise capacity as well as muscle function in small muscle groups in patients with CHF. This new approach broadens the variety of training regimes for older patients with CHF.

Journal article (peer-reviewed)abstract
- OBJECTIVE: To measure walking speed and energy cost in patients with prior stroke with and without a carbon composite ankle foot orthosis. DESIGN: Within-group comparisons of 2 walking conditions. PARTICIPANTS: Convenience sample of 10 hemiparetic patients with a stroke at least 6 months earlier (average age 52 years) habituated to a carbon composite ankle foot orthosis. METHODS: Subjects walked on a treadmill at self-selected speed both with and without ankle foot orthosis for 5 minutes on each occasion. Energy expenditure was measured by breath-by-breath analysis and electrocardiography. Main outcome measures were walking speed, oxygen consumption, heart rate and energy cost per metre. RESULTS: Walking speed: without ankle foot orthosis 0.27 (SEM +/- 0.03) m/s, with 0.34 (+/- 0.06) m/s, difference 20%. Oxygen consumption: without ankle foot orthosis 8.6 (+/- 0.4) ml/kg/min, with 8.8 (+/- 0.5) ml/kg/min. Energy cost: without ankle foot orthosis 0.58 (+/- 0.07) ml/kg/m, with 0.51 (+/- 0.06) ml/kg/m, difference 12%. CONCLUSION: Use of a carbon composite ankle foot orthosis in patients with stroke may increase speed and decrease energy cost during walking.
