and profound hearing impairment treated by cochlear implants (CI). In this study we explore this relationship in sixteen Swedish children with CI. We found that over 60% of the children with CI performed at the level of their hearing peers in a reading comprehension test. Demographic factors were not predictive of reading comprehension, but a complex working memory task was. Reading percentile was significantly correlated to the working memory test, but no other correlations between reading and cognitive/linguistic factors remained significant after age was factored out. Individual results from a comparison of the two best and the two poorest readers corroborate group results, confirming the important role of working memory for reading as measured by comprehension of words and sentences in this group of children.

OBJECTIVE: To explore the long-term benefits of shortened constraint-induced movement therapy (CIMT) in the subacute phase poststroke. DESIGN: A 1-year follow-up after shortened CIMT (3h training/d for 2 wk) where the participants had been randomized to a mitt group or a nonmitt group. SETTING: A university hospital rehabilitation department. PARTICIPANTS: Poststroke patients (N=20, 15 men, 5 women; mean age 58.8 y; on average 14.8 mo poststroke) with mild to moderate impairments of hand function. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Sollerman hand function test, the modified Motor Assessment Scale, and the Motor Activity Log test. Assessments were made by blinded observers. RESULTS: One year after shortened CIMT, participants within both the mitt group and the nonmitt group showed statistically significant improvements in arm and hand motor performance and on self-reported motor ability compared with before and after treatment. No significant differences between the groups were found in any measure at any time. CONCLUSIONS: Shortened CIMT seems to be beneficial up to 1 year after training, but the restraint may not enhance upper motor function. To determine which components of CIMT are most effective, larger randomized studies are needed.

Construct Validity of a New Rating Scale for Self-Reported Impairments in Persons With Late Effects of Polio.
2013
Ingår i: PM & R : the journal of injury, function, and rehabilitation. - : Wiley. - 1934-1563 .- 1934-1482. ; 5:3, s. 176-181

OBJECTIVE: To evaluate the construct validity of a new rating scale for self-reported impairments in persons with late effects of polio. DESIGN: Psychometric analysis of data on self-perceived impairments in persons with prior polio. PARTICIPANTS: Two hundred and seventy-three persons with prior polio (119 men and 154 women; mean age, 63.5 years). METHOD: Rasch analysis of a 13-item rating scale with 5 response categories, in which the participants rated how much they have been bothered by various post-polio-related impairments during the past 2 weeks. RESULTS: The initial analysis showed disordered categories, misfit with some of the items, multidimensionality, and local dependency. After adjustment of the categories, which resulted in a 4-category rating scale, fit to the model was achieved, but the scale still showed signs of multidimensionality. Analyses of local dependency revealed correlations among some of the items, which resulted in a 5 testlet solution, which gave fit to the model and unidimensionality. CONCLUSION: After adjustment of the categories and local dependency, this new rating scale, Self-Reported Impairments in Persons With Late Effects of Polio, can be considered as unidimensional. The good psychometric properties implies that the Self-Reported Impairments in Persons With Late Effects of Polio scale could be a useful rating scale that would increase our understanding of the impairments that persons with late effects of polio can experience. With further refinements, this scale may assist in the planning and evaluation of appropriate rehabilitation interventions.

Effects of cardiorespiratory fitness and muscle-resistance training after stroke
2012
Ingår i: PM&R. - : Wiley. - 1934-1482 .- 1934-1563. ; 4:11, s. 901-907
Tidskriftsartikel (refereegranskat) abstract
Stroke is a leading cause of long-term disability. The physical and cognitive impairments after an ischemic or hemorrhagic stroke often lead to activity limitations and participation restrictions. Many persons after stroke have a sedentary lifestyle, are physically inactive, and have a low fitness level. Physical fitness training is known to be beneficial for persons with a number of comorbid conditions or risk factors for stroke. Although exercise and physical activity are considered valuable, the evidence of their benefits after stroke is still insufficient. In this review, we summarize published randomized controlled trials regarding the effects of cardiorespiratory fitness and muscle-resistance training after stroke on physical function, activity, participation, life satisfaction, and mood. We discuss various barriers that can impede the ability to perform exercise, and the importance of reducing these barriers to increase physical fitness levels after the completion of usual stroke rehabilitation, thereby enhancing leisure, well-being, and participation in society

Brogårdh C, Flansbjer U-B, Lexell J. No effects of whole-body vibration training on muscle strength and gait performance in people with late effects of polio: a pilot study. OBJECTIVE: To evaluate the feasibility and possible effects of whole-body vibration (WBV) training on muscle strength and gait performance in people with late effects of polio. DESIGN: A case-controlled pilot study with assessments before and after training. SETTING: A university hospital rehabilitation department. PARTICIPANTS: People (N=5; 3 men, 2 women; mean age, 64+/-6.7y; range, 55-71y) with clinically and electrophysiologically verified late effects of polio. INTERVENTIONS: All participants underwent 10 sessions of supervised WBV training (standing with knees flexed 40 degrees -55 degrees up to 60 seconds per repetition and 10 repetitions per session twice weekly for 5 weeks). MAIN OUTCOME MEASURES: Isokinetic and isometric knee muscle strength (dynamometer), and gait performance (Timed Up & Go, Comfortable Gait Speed, Fast Gait Speed, and six-minute walk tests). RESULTS: All participants completed the 5 weeks of WBV training, with no discernible discomfort. No significant changes in knee muscle strength or gait performance were found after the WBV training period. CONCLUSIONS: This pilot study did not show any significant improvements in knee muscle strength and gait performance following a standard protocol of WBV training. Thus, the results do not lend support to WBV training for people with late effects of polio.

Self-reported walking ability in persons with chronic stroke and the relationship with gait performance tests
2012
Ingår i: PM&R. - : Wiley. - 1934-1482 .- 1934-1563. ; 4:10, s. 734-738
Tidskriftsartikel (refereegranskat) abstract
Objective: To assess self-reported walking ability in individuals with chronic stroke and to determine the relationship with gait performance tests. Design: Descriptive analysis of a convenience sample. Setting: A university hospital rehabilitation medicine clinic. Participants: Fifty ambulatory community-dwelling poststroke individuals (mean age, 64 years [range, 44-74 years] and mean time since stroke onset 42 months [range, 6-101 months]). Main Outcome Measures: The Walking Impact Scale (the Walk-12) to assess self-reported walking ability, and the Timed "Up & Go" test, 10-m Comfortable Gait Speed and Fast Gait Speed tests, and 6-Minute Walk Test to assess gait performance. Results: A majority of the participants (94%) reported limitations in their walking ability. The most common limitations were related to standing or walking, walking speed and distance, effort, and gait quality aspects. The ability to run was reported as most affected, whereas the need for support indoors or outdoors was least affected. Significant correlations (. P < .01) were found between the Walk-12 and the 4 gait performance tests (ρ = -0.60 to 0.60). Conclusions: Persons with chronic stroke perceive limitations in their walking ability. The relationship between the Walk-12 and the 4 gait performance tests indicates that self-reports and quantitative assessments are associated. Because the Walk-12 reflects broader dimensions than the gait performance tests, it can be a complementary tool when walking ability in persons with chronic stroke is evaluated.

What is the long-term benefit of constraint-induced movement therapy? A four-year follow-up.
2009
Ingår i: Clinical Rehabilitation. - : SAGE Publications. - 1477-0873 .- 0269-2155. ; 23, s. 418-423
Tidskriftsartikel (refereegranskat) abstract
Objective: To evaluate the long-term benefits of constraint-induced movement therapy in chronic stroke.Design: A four-year follow-up after constraint-induced group therapy assessing arm and hand function and self-reported daily hand use.Subjects: Fourteen post-stroke individuals (six women and eight men; mean age 59.6 +/- 12.7 years, range 23-75 years) with mild to moderate impairments of hand function. OUTCOME MEASURES: The Sollerman hand function test and the Motor Activity Log test.Results: Four years after constraint-induced group therapy the participants had maintained their hand function, as measured by the Sollerman hand function test. The self-reported use and quality of movements of the more affected hand, as measured by the Motor Activity Log test, had decreased compared to post-treatment and three months follow-up (P < 0.01), but was still significantly higher than pre-treatment (P < 0.05).Conclusion: There seems to be a long-term benefit of constraint-induced group therapy. Hand function was maintained over time and daily hand use had increased compared to pre-treatment. To provide guidelines about the clinical use of constraint-induced movement therapy further, larger and controlled studies are needed.

Ankle dorsiflexor muscle performance in healthy young men and women: reliability of eccentric peak torque and work measurements
2001
Ingår i: Journal of Rehabilitation Medicine. - : Medical Journals Sweden AB. - 1651-2081 .- 1650-1977. ; 33:2, s. 90-96
Tidskriftsartikel (refereegranskat) abstract
The aims of this study were: (i) to assess the test-retest intrarater reliability of eccentric ankle dorsiflexor muscle performance in young healthy men and women using the Biodex dynamometer; and (ii) to examine different statistical indices for the interpretation of reliability. Thirty men and women (age 22.5 +/- 2.5 years, mean +/- S.D.) performed three maximal eccentric contractions at 30 degrees/second and 90 degrees/second, with 7-10 days between test sessions. Reliability was evaluated with three intraclass correlation coefficients (ICC1,1, ICC2,1 and ICC3,1), and was excellent for peak torque (ICC 0.90-0.96) and good to excellent for work (ICC 0.69-0.83), with no discernible differences among the three ICCs. Method errors, assessed by the standard error of the measurement (S.E.M.) and S.E.M.%, were low. The Bland & Altman graphs and analyses indicated no significant systematic bias in the data. In conclusion, measurements of eccentric ankle dorsiflexor muscle performance in young healthy individuals using the Biodex are highly reliable.

Test-Retest Reliability Of The Life Satisfaction Questionnaire (LISAT-11) And Association Between Items In Individuals With Chronic Stroke
2018
Ingår i: Journal of Rehabilitation Medicine. - : Medical Journals Sweden AB. - 1650-1977 .- 1651-2081. ; 50:8, s. 713-718
Tidskriftsartikel (refereegranskat) abstract
Objective: To evaluate the test-retest reliability of the Life Satisfaction Questionnaire (LiSat-11) and the association between items in individuals with chronic stroke. Design: Test-retest design. Subjects: Forty-five individuals (mean age 65 years) with mild to moderate disability at least 6 months post-stroke. Methods: LiSat-11, which includes 1 global item "Life as a whole" and 10 domain-specific items, was rated on 2 occasions, one week apart. Test-retest reliability was evaluated by kappa statistics, the percent agreement (PA) and the Svensson rank-invariant method. The association between items was evaluated with the Spearman's rank correlation coefficient (rho). Results: The kappa coefficients showed good to excellent agreement (0.59-0.97) and the PA <= 1 point was high (> 89%) for all items. According to the Svensson method, a small systematic disagreement was found for "Partner relationship". The other items showed no systematic or random disagreements. All domain-specific items, except one ("Sexual life") were significantly correlated with "Life as a whole" (rhos 0.29-0.80). Conclusion: LiSat-11 is considered reliable and can be recommended for assessing life satisfaction after stroke. The association between items indicates that LiSat-11 measures various aspects that can impact on an individual's life satisfaction.

2006
Ingår i: Archives of Physical Medicine and Rehabilitation. - : Elsevier BV. - 0003-9993 .- 1532-821X. ; 87:7, s. 974-80
Tidskriftsartikel (refereegranskat) abstract
OBJECTIVE: To assess the relation between knee muscle strength, gait performance, and perceived participation in subjects with chronic mild to moderate poststroke hemiparesis. DESIGN: Descriptive analysis of convenience sample. SETTING: University hospital. PARTICIPANTS: Fifty men and women (mean age, 58+/-6.4y) 6 to 46 months poststroke. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Isokinetic concentric knee extension and flexion strength was measured at 60 degrees /s. Gait performance was assessed by Timed Up & Go, comfortable and fast gait speed, stair climbing ascend and descend, and 6-minute walk test. Perceived participation was assessed with the Stroke Impact Scale. RESULTS: There was a significant correlation (P < .01) between knee muscle strength and gait performance for the paretic but not for the nonparetic lower limb. Strength for the paretic limb explained 34% to 50% of the variance in gait performance; the addition of strength for the nonparetic limb explained at most a further 11% of the variance in gait performance. There was a significant correlation (P < .01) between gait performance and perceived participation; gait performance explained 28% to 40% of the variance in perceived participation. CONCLUSIONS: Knee muscle strength is a moderate to strong predictor of walking ability in individuals with chronic mild to moderate poststroke hemiparesis. Walking ability influences perceived participation, but the strengths of the relations indicate that other factors are also important
