Clinical Trial Summary

The efficacy of an innovative rehabilitation treatment for deficit in time processing is tested in right brain damaged patients.

Patients with a focal lesion following a stroke and without general cognitive impairment will be submitted to computerized tests assessing the ability to estimate time duration (intervals around 7500 ms) and to mental travel in time. Moreover, the impact of the deficit in time processing in everyday life will be evaluated by using ad hoc questionnaires.

Patients will perform tasks before and after two weeks of a new rehabilitation treatment, combining a training for one week with prismatic googles inducing prismatic adaptation (PA) plus Virtual Reality (VR) and a training for one week with neutral googles inducing no-adaptation (NA) plus Virtual Reality. Participants will be randomized into two groups. Each group will be submitted to both treatments in a different order, accordingly with a crossover design.

A greater amelioration in time processing after PA+VR than NA+VR training should be found. Moreover, an improvement in everyday life activities is expected accordingly with the amelioration in time processing.

Description:

Time processing involves different abilities - i.e. estimating the duration of an event and moving in past and future time - and it is a fundamental ability in everyday life. However, in neuropsychology, time processing is routinely neglected in the assessment of cognitive deficits in brain-damaged patients. This is surprising since time is an important function that permeates our activities: we perceive mismatches in lip reading (milliseconds), we estimate how long it takes to be ready for work (minutes), and we plan how long it will take a manuscript to be accepted (usually months). Thus, impairment in processing time has important consequences in daily life.

For instance, it is known that right brain damaged (RBD) patients with spatial attentional deficit (neglect) are impaired in estimate the duration of a time interval as well as in the ability of mentally moving in time (Mental Time Travelling).

Previous studies have demonstrated an improvement of time estimation and mental time travel after a leftward shift of spatial attention induced by a single session of prismatic adaptation (PA). Moreover, a recent study investigated the long-term duration of the benefits induced by 10 daily sessions of PA treatment on mental time travel and functional abilities in neglect patients. Results suggest that the PA treatment induces a long-lasting and stable ameliorations of mental time travel and functional competences.

To generalize the effects of PA treatment to everyday life, here we propose to combine PA with a virtual reality training (VR). VR has recently been used as an effective tool both for the assessment and rehabilitation of cognitive deficits, because it allows post-stroke patients to interact with ecological environments similar to the real ones, but in a safe and controlled condition.

Aim of this study is to set up a rehabilitation procedure for temporal deficits, combining a well-established PA procedure with an innovative, more engaging and ecological VR approach.

Patients will perform tasks before and after two weeks of a new rehabilitation treatment, combining a training for one week with prismatic googles inducing prismatic adaptation (PA) plus Virtual Reality (VR) and a training for one week with neutral googles inducing no-adaptation (NA) plus Virtual Reality. Participants will be randomized into two groups. Each group will be submitted to both treatments in a different order, accordingly with a crossover design.

A greater amelioration in time processing after PA+VR than NA+VR training should be found. Moreover, an improvement in everyday life activities is expected accordingly with the amelioration in time processing.

Intervention

Behavioral:
• Prismatic googles inducing prismatic adaptation (PA) associated to Virtual Reality (VR)
The experimental condition consists of PA procedure associated to VR task: the pointing task will be followed by 5 sessions of VR task. Pointing task. Patients will perform a session of 90 pointing movements toward a visual target presented in a variety of positions on the right, the left or at the center of the visual field. This pointing task will be performed with prismatic googles inducing a rightward shift of the visual field (experimental condition). After lenses removal, a leftward shift of spatial attention will be produced. Virtual Reality task consists of a 3D computer-generated virtual environment that will be displayed on a desktop VR computer monitor. A joystick will provide the graphical interface for patients by allowing user-friendly exploration of virtual scenarios. Patients will be presented 16 actions, with dynamic simulations of real life situations. They will verbally estimate and reproduce the duration of each previously presented action.

Other:
• Neutral googles inducing no-adaptation (NA) associated to Virtual Reality (VR)
The sham condition of this study consists of NA procedure associated to VR task: the pointing task will be followed by 5 sessions of VR task. Pointing task. Patients will perform a session of 90 pointing movements toward a visual target presented in a variety of positions on the right, the left or at the center of the visual field. This pointing task will be performed with neutral goggles (control condition), which should not induce a shift of the visual field and of spatial attention. Virtual Reality task consists of a 3D computer-generated virtual environment that will be displayed on a desktop VR computer monitor. A joystick will provide the graphical interface for patients by allowing user-friendly exploration of virtual scenarios. Patients will be presented 16 actions, with dynamic simulations of real life situations. They will verbally estimate and reproduce the duration of each previously presented action.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Mental Time Travel Ability on the Mental Time Travel (MTT) Task	In the MTT task participants are listened to auditory stimuli consisting of brief descriptions of personal and non-personal events. They are required to project themselves in the past (10 years ago), present or future (10 years from now) and to verbally determine whether each event has already happened (relative past event) or is yet to happen (relative future event) with respect to the specific self-location in time (past, present and future).; Error rates and reaction times will be recorded and analyzed. The improvement will be defined as changes in the Inverse Efficiency (IE) ability: reaction times/accuracy.	baseline, after one week treatment (T1), after two weeks treatment (T2), one week after the end of treatment (follow-up)
Primary	Change in Time Estimation Ability on the Time Estimation Task	The Time Estimation task consists of a red square that is displayed for different durations (3500, 5500, 7500, 9500, 11500 ms) on the computer screen. Participants are instructed to verbally judge whether the duration of each stimulus is "short" or "long" with respect to previously acquired pair of reference durations (3500 and 11500 ms).; A psychophysical response function will be created for each participant by calculating the proportion of "long" responses: the Point of Subjective Equality (PSE) is the duration at which a participant is equally likely to classify the stimuli as short or long. An increase of "long" response after treatment, as compared to baseline performance, induces a decreased PSE, reflecting a relative shift towards overestimation of temporal midpoint. Conversely, an increase of "short" responses after treatment, as compared to baseline performance, induces an increased PSE, reflecting a relative shift towards underestimation of temporal midpoint.	baseline, after one week treatment (T1), after two weeks treatment (T2), one week after the end of treatment (follow-up)
Primary	Change in Time Reproduction Ability on the Time Reproduction Task	In the Time Reproduction task a blue square is presented for a variable time interval (3500, 5500, 7500, 9500, 11500 ms) on the computer screen. Next, a red square appears on the screen and participants are instructed to reproduce the entire duration of the preceding blue square by pressing the space bar on the keyboard.; For each subject, the reproduced time intervals before PA will be subtracted from the reproduced time intervals after PA. Thus, this difference will be positive when reproduced time will be longer after than before treatment (underestimation of time duration) and negative when reproduced time will be shorter after than before treatment (overestimation of time duration).	baseline, after one week treatment (T1), after two weeks treatment (T2), one week after the end of treatment (follow-up)
Secondary	Assessment of General Cognitive Functioning on the Mini Mental State Examination (MMSE)	The MMSE is a 30-point questionnaire that examines functions including registration (repeating named prompts), attention and calculation, recall, language, ability to follow simple commands and orientation. The score ranges from 0 to 30 (cut-off = 24).	baseline
Secondary	Assessment of Verbal Comprehension on the Token Test	The Token Test is a test of auditory language processing in which participants are asked to manipulate tokens of different shapes, sizes, and colors in response to increasingly complex instructions. One point is credited for a correct performance on the first presentation and 0.5 point if the performance is correct only on the second presentation. The score ranges from 0 to 36 (cut-off = 26,50).	baseline
Secondary	Assessment of Unilateral Spatial Neglect on the Behavioral Inattention Test (BIT)	The BIT is composed of two scales, the Conventional scale and the Behavioral scale. Participants will be administered the Conventional scale, which includes 6 tasks: line crossing, letter cancellation, star cancellation, figure and shape copying, line bisection and representational drawing. The score ranges from 0 to 146 (cut-off = 129).	baseline
Secondary	Assessment of Frontal Functions on the Wisconsin Card Sorting Test (WCST)	In the WCST, people have to classify cards according to different criteria. There are four different ways to classify each card, and the only feedback is whether the classification is correct or not. The classification rule changes every 10 cards. Three scores will be calculated: global score, perseveration errors and non-perseveration errors. The global score is computed by subtracting from the total number of administered trials the number of categories completed multiplied by ten = [n° of trials - (n° of achieved categories x 10)].; The score ranges from 128 to 0, i.e. the lower the score, the better the performance.	baseline
Secondary	Assessment of Memory on the Rey's 15 Words Auditory Learning Test	The test is designed as a list-learning paradigm in which the participant hears a list of 15 nouns and is asked to recall as many words from the list as possible (five repetitions of free-recall). After a 15 min delay, the participant is asked to again recall the words from the list. It provides two scores: immediate (range 0-75) and delayed recall (range 0-15), i.e. the higher the score, the better the performance.	baseline
Secondary	Change in Unilateral Spatial Neglect on the Bells Cancellation Test	The subject is required to cross out the bells that are scattered among several different shapes on a sheet of paper. Two indices of neglect will be calculated: total number of omissions (cut-off < 5) and number of left omissions (cut-off < 5), i.e. the difference between the number of targets crossed out on the right side and the number of targets crossed out on the left side (asymmetry score).	baseline, after two weeks treatment (T2), one week after the end of treatment (follow-up)
Secondary	Change in Unilateral Spatial Neglect on the Apples Cancellation Test	This is a cancellation task in which outline drawings of 150 apples are shown pseudorandomly scattered over a sheet of A4 paper presented in a landscape orientation. All of the apples are presented in an upright position. One-third of the apples are full (targets) and two-thirds are open on either the left or the right side (distractors). Participants are asked to cross out all the full apples and to ignore the distractors. Three scores will be calculated: full apples barrage (cut-off = 45), full apples asymmetry (cut-off = 2), and incomplete apples asymmetry (cut-off = 1).; The full apples asymmetry (the difference between the number of targets selected on the right side and the number of targets selected on the left side) represents the score for egocentric neglect. The incomplete apples asymmetry (total left openings minus total right openings) represents the score for allocentric neglect.	baseline, after two weeks treatment (T2), one week after the end of treatment (follow-up)
Secondary	Change in Frontal Functions on the Frontal Assessment Battery (FAB)	The FAB is a brief battery of six neuropsychological tasks designed to assess frontal lobe function at bedside. The six tasks explore: conceptualization and abstract reasoning, lexical verbal fluency and mental flexibility, motor programming and executive control of action, self-regulation and resistance to interference, inhibitory control, and environmental autonomy.; Each task scores from 0 (pathologic) to 3 (best performance), for a total maximum score of 18.	baseline, after two weeks treatment (T2)
Secondary	Change in Verbal Estimation Ability on the Time and Weight Estimation Test (STEP)	The STEP assesses aspects of executive functioning related to cognitive estimation ability. The questionnaire is composed of two distinct ten-item sections, focusing on time (e.g., How long does it take to have a shower?) and weight (e.g., How heavy is a pair of jeans?) estimations. Each item scores from 0 (bizarre estimation) to 3 (best estimation), for a total maximum score for each section of 30, with a cut-off value for normality above 20 for each section.	baseline, after two weeks treatment (T2)
Secondary	Change in Verbal Estimation Ability on the Cognitive Estimation Task (CET)	The test comprised 21 questions that required participants to give oral, numerical responses. Two different scoring procedures will be considered: absolute error score and bizarreness. The total score for all 21 items ranges from a best of zero to a worst of 42. The greater the error score, the poorer the performance on the CET (cut-off = 18). The total bizarreness score ranges from 0 and 21 (cu-off = 4). The higher the bizarreness score, the greater the impairment in cognitive estimation.	baseline, after two weeks treatment (T2)
Secondary	Change in Functional Abilities on the Questionnaire of Temporal Ability	The Questionnaire of temporal ability is a new instrument to measure the ability to locate daily activities in time.	baseline, after two weeks treatment (T2), one week after the end of treatment (follow-up)
Secondary	Change in Functional Abilities on the Motricity Index	The Motricity Index is a standardized mobility scale, designed to measure the motor impairment of the trunk and the right and left upper and low limbs. Each component part of the index expresses the strength of the part of the body that is evaluated. The score ranges from 0 (low motor functions) to 100 (high motor functions).	baseline, after two weeks treatment (T2)
Secondary	Change in Functional Abilities on the Activities of Daily Living (ADL)	Eleven ADL areas, such as walking, dressing, cleaning, and feeding, are assessed to measure the degree of independence in activities of daily living. Each activity is evaluated through a 5-points questionnaire (1 = completely independent, 5 = completely dependent), with a total score ranging from 11 (high independence in ADL) to 55 (high dependence in ADL).	baseline, after two weeks treatment (T2), one week after the end of treatment (follow-up)
Secondary	Change in Functional Abilities on the Functional Independent Measure (FIM)	The FIM is an 18-item, 7-level scale developed to uniformly assess severity of patient disability and medical rehabilitation functional outcome. Scores range from 18 (lowest) to 126 (highest) indicating level of function.	baseline, after two weeks treatment (T2)
Secondary	Change in Spatial Working Memory on the Spatial Working Memory Test	Participants are presented with a paper sheet composed of 24 identical Os and 24 different drawings of common objects and they are instructed to cancel all Os, marking each once only. The score is the number of re-cancellations, that will be scored for any additional cross (an extra single line is scored as 0.5 re-cancellation).	baseline, after two weeks treatment (T2)
