Prismatic Adaptation for Rehabilitation of Postural Imbalance After Stroke

France28 participantsStarted 2017-12-04

Plain-language summary

Postural imbalance after stroke leads to limitations of activity and a worse autonomy. The postural imbalance is increased in right supratensorial stroke (RSS) compared to left supratensorial stroke. The evidences for the rehabilitation of postural imbalance are weak. Likewise, disorders of spatial reference frames are increased in RSS. The postural imbalance is correlated with the disorders of spatial reference frames in RSS patients. Prismatic adaptation (PA) is often used for the rehabilitation of unilateral spatial neglect after RSS. Several studies have demonstrated a peculiar expansion of sensorimotor after-effects to spatial cognition. An immediate effect of reduction in postural imbalance have been showed in acute RSS. Therefore, it is interested to investigate the immediate and delayed effects of PA on the postural balance and the spatial reference frames in chronic RSS to purpose a new therapeutic approach. The hypothesis of the study is that PA would improve the postural balance (activity) of chronic RSS patients by a reduction in mediolateral postural asymmetry, resulting from a " bottom-up " action of PA on spatial reference frames.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

Balance: The inter-group difference of within-group changes for the Berg Balance Scale (BBS)

Timeframe: Change from baseline (mean of the 2 pre-tests) at 7 days after the end of treatment (3 weeks about after the baseline)
