About this study

Official title: Efficacy of Task-specific Training on Physical Activity Levels of People With Stroke: A Randomized Controlled Trial

The majority of people after stroke demonstrate mobility limitations, which may reduce their physical activity levels. Task-specific training has shown to be an effective intervention to improve mobility in individuals with stroke, however, little is known about the impact of this intervention on levels of physical activity. The main objective will be to investigate the efficacy of a task-specific training, focused on both upper and lower limbs, in improving physical activity levels and mobility in individuals with stroke. The secondary objective will be to investigate the effect of the training, in improving muscle strength, exercise capacity, and quality of life. A randomized controlled trial with blinded assessment will assign eligible participants to either: 1) experimental group or 2) control group. Participants will receive interventions three times per week over 12 weeks. The experimental group will undertake task-specific training, while the control group will undertake global stretching and memory exercises, and health education sessions. Primary outcomes will include measures of physical activity levels and mobility, whereas secondary outcomes will be muscle strength, exercise capacity, and quality of life. The outcomes will be measured at baseline, 12 weeks post-intervention, and four and 12 weeks follow-up. The findings of this trial have the potential to provide important insights regarding the effects of task-specific training, focused on both upper and lower limbs, in preventing secondary post-stroke complications and improving the participants' general health through changes in physical activity levels.

Read the detailed description

The sample size was calculated to detect a between-group difference of 0.15 m/s in gait speed, with 80% power, at a two-tailed significance level of 0.05. In an RCT with a similar population and intervention (Yang et al. 2006) gait speed for the control and experimental groups at baseline was 0.78±0.14 m/s and 0.84±0.13 m/s and after were 0.78±0.15 m/s (p=0.8) and 0.93±0.14 m/s (p<.001), respectively. Based on these values, 15 participants per group will be required (a total of 30 participants). Assuming a dropout rate of 15%,66 a total of 36 participants will be recruited (18 per group).

Data analyses will be performed by the SPSS for Windows® (release 17.0, SPSS Inc., Chicago, IL, USA). Descriptive statistics will be carried-out for all outcome variables. Differences between the groups at baseline will be investigated with the independent Student's t-tests for all variables related to the demographic and clinical characteristics. If differences between the groups at baseline exist, analysis of covariance will be used to eliminate the influence of extraneous factors.

The effects of the interventions will be analysed in two ways, namely from the data collected and by intention-to-treat analyses, where the last available value in the dropouts will be carried forward to represent the missing data. Analyses of variance with repeated measures (2×4) will be employed to investigate the mean and interaction effects between the groups (intervention×control) and the time (preintervention, postintervention, and follow-up) for the primary and secondary outcomes. Group descriptions will be presented as mean (SD) and effect sizes with 95% confidence intervals (CIs) will be reported.

The effect sizes will be calculated to determine the magnitude of the differences between the groups. The differences between the two mean values will be expressed in units of their SD, expressed as Cohen's d, or mean results for the experimental group minus the mean results for the control group, divided by the SD of the control group. Effect sizes between 0.2 and 0.5 will be considered small; between 0.5 and 0.8, medium; and above 0.8, large.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Task-specific trainingOther

    Also called Task-oriented training

    The task-specific training will be composed by 30 minutes for upper limb and 30 minutes for lower limb tasks. Subjects will performed five minutes of exercise in each station of the circuit and only the last station will last 10 minutes and will involve a walking training with auditory stimulation. Individuals will be encouraged to work as hard as possible at each station and verbal feedback and instructions aimed at improving performance will be taken. Between each task, the participants will be allowed to rest for at least 1-2 minutes, and individual adjustments will be carried out for better adaptations to the training.

  • Global stretching, memory exercises, health care orientationOther

    The control intervention will be composed by 40 minutes for global stretching, 20 minutes of memory exercises and health care orientation

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in Physical activity levels - physical activity monitor (time frame: At baseline, after 12 weeks post-intervention, four and 12 weeks of follow-up). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02937480, which also lists 28 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2019.
