    • Background For some of the most commonly used motor measures, psychometric properties, and minimal detectable change (MDC95) remain largely unknown, limiting the interpretability of tests. Objective The aim was to establish intrarater reliability, MDC95 and floor- and ceiling effects for a modified version of the Motor Assessment Scale (M-MAS UAS-99). Methods Data was derived from an intervention study that enrolled 41 individuals with chronic stroke. Test scores from two subsequent assessments with 3 weeks apart were used for establishing the floor and ceiling effect, the intraclass correlation coefficient (ICC[2,1]), standard error mean (SEM) and the MDC95 for the total score, and subdomains of the M-MAS UAS-99. Results The intrarater reliability was excellent with an ICC[2,1] between 0.970 and 0.995 for both total score and subdomains. The MDC95 for the M-MAS UAS-99 total score was 1.22 which means >= 2.0 points on an individual basis. For bed mobility subdomain, a ceiling effect was seen, but not for the total score of the test. No floor effect was seen for the test. Conclusion M-MAS UAS-99 has excellent intrarater reliability. Any individual increase in test scores must reach 2.0 to be considered a true change.

  • Comfortable and Maximum Gait Speed in Individuals with Chronic Stroke and Community-Dwelling Controls
  • 2021
  • Ingår i: Journal of Stroke and Cerebrovascular Diseases. - : Elsevier BV. - 1052-3057 .- 1532-8511. ; 30:10
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The relationship between maximum and comfortable gait speed in individuals with mild to moderate disability in the chronic phase of stroke is unknown. Objective: This study examines the relationship between comfortable and maximum gait speed in individuals with chronic stroke and whether the relationship differ from that seen in a community-dwelling elderly population. Further, we investigate the influence of age, gender, time post-stroke and degree of disability on gait speed. Materials and methods: Gait speed was measured using the 10-meter walk test (10MWT) and the 30-meter walk test (30MWT) in 104 older individuals with chronic stroke and 154 community-dwelling controls, respectively. Results: We found that the maximum gait speed in individuals with stroke could be estimated by multiplying the comfortable speed by 1.41. This relationship differed significantly from that of the control group, for which the corresponding factor was 1.20. In the stroke group, age, gender and time post-stroke did not affect the relationship, whereas the degree of disability was negatively correlated with maximum speed - but not when included in the multiple analysis. In the community-dwelling population, higher age and female gender had a negative relationship with maximum gait speed. When correcting for those parameters, the coefficient was 1.07. Conclusions: The maximum gait speed in the chronic phase of stroke can be estimated by multiplying the individual's comfortable gait speed by 1.41. This estimation is not impacted by age, gender, degree of disability and time since stroke. A similar but weaker relationship can be seen in the community-dwelling controls.

  • Effects of enriched task-specific training on sit-to-stand tasks in individuals with chronic stroke
  • 2024
  • Ingår i: NEUROREHABILITATION. - 1053-8135 .- 1878-6448. ; 54:2, s. 297-308
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Approximately 80% of stroke survivors experience motor impairment of the contralateral limb that severely affects their activities of daily living (ADL). OBJECTIVE: To evaluate whether an enriched task-specific training (ETT) program affected the performance and kinetics of sit-to-stand (STS) tasks. METHODS: The study was part of an exploratory study with a within-subject, repeated-measure-design, with assessments before and after a three-week-long baseline period, and six months after the intervention. Forty-one participants underwent assessments of strength and endurance measured by the 30-second-chair-stand test (30sCST). The STS-kinetics, including the vertical ground reaction force (GRF) during STS, were analysed in an in-depth-subgroup of three participants, using a single-subject-experimental-design (SSED). For kinetic data, statistical significance was determined with the two-standard deviation band method (TSDB). RESULTS: After the baseline period, a small increase was seen in the 30sCST (from 5.6 +/- 4.5 to 6.1 +/- 4.9, p = 0.042). A noticeable significant change in the 30sCST was shown after the intervention (from 6.1 +/- 4.9 to 8.2 +/- 5.4, p < 0.001), maintained at six months. The in-depth kinetic analyses showed that one of three subjects had a significant increase in loading of the affected limb post-intervention. CONCLUSION: ETT can produce long-term gains in STS performance. Weight-bearing strategies could be one of several factors that contribute to improvements in STS performance in the chronic phase after stroke.

  • Enriched, task specific therapy in the chronic phase after stroke
  • 2021
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Recovery and improvement of motor functions and abilities after stroke depend on the spontaneous recovery process but also on the reorganization of neural mechanisms. In animal studies, an Enriched Environment (EE) has proved to be an effective intervention for boosting brain plasticity and recovery after stroke. Until recently, an EE has been a laboratory phenomenon with few attempts of translation to the clinical setting. The overall aim of this thesis was to study whether enriched task-specific therapy (ETT) contributed to any changes with respect to function, activity, participation and different aspects of health in individuals with chronic stroke. This thesis includes four papers. In study I, a longitudinal uncontrolled observational study, with a within-subject, repeated-measures design, we studied whether ETT contributed to any motor or health-related changes, in individuals with chronic stroke. The ETT-interventions was a 3-week, high intensity, task specific training program in an EE in Spain, where also social and sensory components was included. The 39 participants who completed the ETT program did improve their functional motor ability, balance, gait speed and walking endurance, and were shown to achieve gains in multiple dimensions of health. The improvements were sustained at the 6-month follow-up. In study II, we explored the experiences of individuals who participated in the ETT program using focus group interviews. The analyses, which was performed using qualitative content analysis, showed that ETT may lead to perceived improvements in function, knowledge, new insights and perceptions of rehabilitation needs and can have enriching emotional impacts. In study III, a longitudinal observational study with a single-subject experimental design, we studied the gait and movement pattern in a three dimensional gait lab. Four participants were studied, of whom two had significant improvements in gait kinematics, symmetry, and spatiotemporal variables after the intervention. In study IV, a cross-sectional observational controlled study, we studied the relationship between comfortable and maximum gait speed in individuals with chronic stroke, and in a community dwelling elderly control group. We found that the maximum gait speed in the stroke individuals can be predicted by the comfortable gait speed, with a coefficient at 1.41, which differed from the control group, which uncorrected coefficient was found to be 1.20. In conclusion, this thesis shows that, ETT applied to individuals in a chronic phase after stroke, had impacts on functional motor ability, gait speed, balance, multiple dimensions of health and led to different emotional impacts. Further, ETT might affect the kinematic gait pattern, but in order to understand the underlying mechanisms of recovery and improvement, further research is needed.

    • There is a need to translate promising basic research about environmental enrichment to clinical stroke settings. The aim of this study was to assess the effectiveness of enriched, task-specific therapy in individuals with chronic stroke.This is an exploratory study with a within-subject, repeated-measures design. The intervention was preceded by a baseline period to determine the stability of the outcome measures. Forty-one participants were enrolled at a mean of 36 months poststroke. The 3-week intervention combined physical therapy with social and cognitive stimulation inherent to environmental enrichment. The primary outcome was motor recovery measured by Modified Motor Assessment Scale (M-MAS). Secondary outcomes included balance, walking, distance walked in 6 minutes, grip strength, dexterity, and multiple dimensions of health. Assessments were made at baseline, immediately before and after the intervention, and at 3 and 6 months.The baseline measures were stable. The 39 participants (95%) who completed the intervention had increases of 2.3 points in the M-MAS UAS and 5 points on the Berg Balance Scale (both P < 0.001; SRM >0.90), an improvement of comfortable and fast gait speed of 0.13 and 0.23 m/s, respectively. (P < 0.001; SRM = 0.88), an increased distance walked over 6 minutes (24.2 m; P < 0.001; SRM = 0.64), and significant improvements in multiple dimensions of health. The improvements were sustained at 6 months.Enriched, task-specific therapy may provide durable benefits across a wide spectrum of motor deficits and impairments after stroke. Although the results must be interpreted cautiously, the findings have implications for enriching strategies in stroke rehabilitation.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A304).

  • Experience of enriched rehabilitation in the chronic phase of stroke
  • 2022
  • Ingår i: Disability and Rehabilitation. - : Informa UK Limited. - 0963-8288 .- 1464-5165. ; 44:3, s. 412-419
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose:In this study, we explored the experiences of patients who participated in an enriched task-specific therapy (ETT) program in the chronic phase after stroke. Method:Focus group interviews were conducted with twenty participants with a mean time since stroke of 30 months and mean age 61 years, who completed the ETT program including task-specific training and environmental enrichment. ETT was delivered 3.5-6 h per day, 51/2 days per week for 3 weeks in a climate suitable for both indoor and outdoor activities. The training consisted of repetitive mass practice of gradually increasing difficulty. Directly after the intervention, qualitative interviews were conducted in six focus groups. The interviews were analysed with qualitative content analysis. Results:Three main categories describing the informants' experiences of the ETT program were identified. These categories were; 1.The program-different and hard- highlighting the participants view of the ETT as strenuous and different in nature; 2.My body and mind learn to know better- describing positive changes in participants' body function and functional ability as well as behavioural changes experienced throughout the ETT; and 3.The need and trust from others- emphasizing the perceived importance of trust in rehabilitation clinicians and the support of family and other participants. From these categories, a main theme emerged:It's hard but possible-but not alone! Conclusion:A therapy program including task-specific training and environmental enrichment may provide late-phase stroke survivors with perceived improvements in functional ability, knowledge insights, perceptions of rehabilitation needs and enriching emotional impacts.

  • Gait Kinematics and Spatiotemporal Variables after Enriched, Task-Specific Therapy in the Chronic Phase after Stroke. A Single-Subject Experimental Design Study
  • 2021
  • Ingår i: Archives of Clinical and Medical Case Reports. - : Fortune Journals. - 2575-9655. ; 5:2, s. 325-341
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: In this single-subject experimental design study, we investigated the effect of late-phase stroke rehabilitation on gait pattern. Methods: A subgroup from a previous clinical study, four men in the chronic phase after stroke, received 3 weeks of enriched and task-specific therapy (ETT) consisting of task-specific exercise, socialization, sensory and cognitive stimulation in a Mediterranean climate. Spatiotemporal gait variables, kinematics and symmetry were measured before and after the intervention in an advanced gait laboratory. Statistical significance was determined with the two-standard deviation band method. Results: Subject 1 had kinematic improvements (increased knee flexion during swing and dorsiflexion during stance) and spatiotemporal gains (increased speed, double-limb support, stride length and cadence) after ETT. Subject 2 had improved swing time symmetry ratio but no spatiotemporal or kinematic improvements. Subject 3 had gains in speed, stride width and length, and knee flexion during swing. Subject 4 had a change in cadence but no gain in kinematics, nor symmetry. Conclusions: Two of the four participants had significant improvements in gait kinematics, symmetry, and spatiotemporal variables after the intervention. Future research should consider the potential effects of ETT with the aim of validating the conclusions that can be drawn from this study.
