Brief Summary:

The study aims to demonstrate improvement of daily life functioning and improvement of cognitive tests in post traumatic brain injury (TBI) patients suffering from working memory deficit, by a 3-month specific cognitive rehabilitation program, in comparison with patients with usual non-specific rehabilitation of same duration.

As secondary objectives, the study aims to:

  • demonstrate improvement of specific neuropsychological tests of working memory;
  • demonstrate improvement of non-specific tasks involving working memory;
  • assess the evolution in not-targeted domains by the specific rehabilitation, which would give evidence of a global cognitive stimulation effect;
  • demonstrate improvement of social integration ability and quality of life;
  • demonstrate persistence of effects at 3 months and 6 months after the end of treatment;
  • demonstrate the acceptability, the tolerance and the feasibility of rehabilitation.

Detailed Description:

Working memory is an essential cognitive function which allows to store briefly and treat simultaneous informations, but is often altered after a moderate to severe TBI. This alteration results in disabilities and social integration difficulties in the post TBI patients. The study team had developped a standardized and hierarchized rehabilitation program of working memory. Several experiments have shown the efficacy of the program which is now used in routine care by speech-language pathologists and neuropsychologists. However it is necessary to provide a robust demonstration of its efficacy in improving function in daily life.

This randomized multicenter study will be performed in 6 centers in the area of Île-de-France. 54 patients will be randomized 1:1 to receive either specific rehabilitation of working memory or non-specific rehabilitation. A 10-month follow-up is planned for patients of the two arms.

Arm Intervention/treatment
Experimental: Specific rehabilitation of working memory
Specific rehabilitation of working memory according to hierarchized rehabilitation.
Other: Specific rehabilitation

Experimental rehabilitation of working memory:

3 sessions per week during 3 months, for a total 36 sessions.


Active Comparator: Control group
Non-specific rehabilitation of working memory, usual therapy.
Other: Non-specific rehabilitation
Usual non-specific rehabilitation treatment for moderate to severe TBI in healthcare facilities: 2-3 sessions per week for 3 months.




Primary Outcome Measures :
  1. Proportions of simultaneous responders [ Time Frame: 3 months after the first rehabilitation session ]

    A patient will be considered as a responder if he improves simultaneously on the Working Memory Questionnaire (WMQ) and the Brown-Peterson Task.

    Proportions will be calculated of patients simultaneously improving on the Working Memory Questionnaire (WMQ) and the Brown-Peterson Task:

    • increase of at least 12 points on WMQ scale,
    • at least 13% score improvement on the verbal or visuo-spatial Brown-Peterson Task.


Secondary Outcome Measures :
  1. Working Memory Questionnaire during rehabilitation program [ Time Frame: At baseline, 3 months, 6 months and 9 months ]

    The Working Memory Questionnaire (WMQ), an auto-questionnaire elaborated by the study team, will be used.

    The WMQ is a self-administered scale, addressing three dimensions of working memory: short-term storage, attention, and executive control.

    It is a self-assessment questionnaire comprising 30 questions scored on a five-point Likert scale, ranging from 0 ("no problem at all") to 4 ("very severe problem in everyday life"). The total score will be used.


  2. Cognitive task of working memory [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    Working memory span tasks

  3. Cognitive task of working memory [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    Verbal and visuospatial working memory.

  4. Cognitive task of working memory [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    n-back task

  5. Cognitive task of working memory [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    Brown-Peterson Visual.

  6. Cognitive task of working memory [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    reading span task.

  7. Cognitive task of working memory [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    Working Memory Index (WISC-IV).

  8. Cognitive task of working memory [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    divided attention task

  9. Arithmetic resolution [ Time Frame: At baseline, 3 months and 6 months ]
    Non-specific tasks involving working memory: arithmetic resolution ability by WAIS index

  10. Non-targeted cognitive measurements [ Time Frame: At baseline, 3 months and 6 months ]
    Executive functions will be assessed.

  11. Non-targeted cognitive measurements [ Time Frame: At baseline, 3 months and 6 months ]
    Long-term memory will be assessed.

  12. Non-targeted cognitive measurements [ Time Frame: At baseline, 3 months and 6 months ]
    The speed of treatment will be assessed.

  13. Social functioning assessement [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    Assessed by Manual for Sydney Psychosocial Reintegration Scale (SPRS)

  14. Quality of life assessment [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    Assessed by Qolibri scale

  15. Quality of life assessment [ Time Frame: At baseline, 3 months, 6 months and 9 months ]
    Assessed by EQ5D-5

  16. Acceptability [ Time Frame: At baseline, 3 months and 6 months ]
    Compliance of rehabilitation program: duration of training of speech-language pathologist and psychologist to the rehabilitation program.

  17. Acceptability [ Time Frame: At baseline, 3 months and 6 months ]
    Compliance of rehabilitation program: duration of session.

  18. Acceptability [ Time Frame: At baseline, 3 months and 6 months ]
    Compliance of rehabilitation program: patient's satisfaction of care (Client Satisfaction Questionnaire (CSQ-8)).

  19. Acceptability [ Time Frame: At baseline, 3 months and 6 months ]
    Compliance of rehabilitation program: presence during rehabilitation session of working memory.
