Traumatic brain injury (TBI) is one of the leading causes of serious, life-long disability among adolescents and young adults. Especially the cognitive, emotional, and motors deficits caused by TBI often impair everyday psychosocial functioning, quality of life and ability to work. The purpose of the study is to determine the long-term effect of music-based rehabilitation on cognitive, motor, emotional, and social recovery after TBI in adolescents and young adults, and to study the neural mechanisms that underlie behavioural recovery and the efficacy of music.

Traumatic brain injury (TBI) is one of the leading causes of serious, life-long disability among adolescents and young adults. Especially the cognitive, emotional, and motors deficits caused by TBI often impair everyday psychosocial functioning, quality of life (QoL) and ability to work dramatically, thereby bringing about a lot of suffering and burden to the patients and their families as well as substantial social and economic costs to the society. Early rehabilitation is highly important for restoring lost skills and functioning, but often very difficult given the severity and extent of the TBI symptoms and the high strain that the available rehabilitation methods put on the patients. Music therapy is a highly motivating, versatile, and applicable form of TBI rehabilitation, but currently there is little scientific evidence for its efficacy or mechanisms in the TBI population. The purpose of the present project is to determine the long-term effect of Music-based Neurological Rehabilitation (MBNR) on cognitive, motor, emotional, and social recovery after TBI in adolescents and young adults, and to study the neural mechanisms that underlie behavioural recovery and the efficacy of music. The study is a single-blind, cross-over randomized controlled trial (RCT) involving 60 adolescents and young adults with a subacute moderate / severe TBI. During an 18-month follow-up, the patients receive MBNR (30 session, 3 x week, 1 hour sessions) and/or Standard Care (SC). The MBNR intervention utilizes structured cognitive-motor training with drums and creative musical expression (music playing, song writing) with piano that are geared towards engaging and training attention, executive functions, working memory, and upper-extremity functions and for enhancing emotional self-expression, adjustment, and mood after TBI. The SC consists of other types of conventional rehabilitation (e.g., physical therapy, neuropsychological rehabilitation) and medical care for TBI provided in private or public health care. Half of the patients receive the MBNR intervention during the first 10-week period and half during the second 10-week period (in addition, all patients receive SC during the whole follow-up period). Outcome measures comprise neuropsychological tests (measuring executive functions, attention, reasoning, and working memory and learning), neurological scales (measuring neurological symptoms, functional outcome, adjustment, and participation), motor tests (measuring motor dexterity, coordination, and upper limb functioning), and structural and functional magnetic resonance imaging (MRI/fMRI, measuring gray and white matter structure and integrity and auditory-motor neural processing) performed at the start of the study (baseline), after the first 10-week period (3-month stage) and after the second 10-week period (6-month stage). At these time points as well as 12 months later (18-month stage), the patients and their caregivers are also given questionnaires measuring executive functions, depression symptoms, quality of life, and caregiver well-being and burden.

The patients receive 10 weeks of Music-based Neurological Rehabilitation (MBNR) and Standard Care (SC) followed by 10 weeks of SC only.

The patients receive 10 weeks of Standard Care (SC) only followed by 10 weeks of Music-based Neurological Rehabilitation (MBNR) and SC.

Music-based Neurological Rehabilitation (MBNR) will involve 10 weeks of individual training (30 sessions, 1 hour per session, 3 days per week) given by a trained music therapist. The MBNR protocol utilizes structured cognitive-motor training with drums (drum set, djembe drums) and creative musical expression (music playing, song writing) with piano that are geared towards engaging and training attention, executive functions, working memory, and upper-extremity functions and for enhancing emotional self-expression, adjustment, and mood after TBI.

Standard Care (SC) consists of other types of conventional rehabilitation (physical therapy, occupational therapy, speech therapy, and/or neuropsychological rehabilitation) and medical care for TBI that the patients receive in Finnish private or public health care.

Executive Functions (EF) are assessed using the Behavior Rating Inventory of Executive Functions (BRIEF-A, both self-report and informant-report versions) questionnaire and following cognitive tests: Frontal Assessment Battery (FAB, measure of overall EF), Number-Letter Task (measure of set-shifting ability), Simon Task (measure of inhibition), and Auditory N-back Task (measure of working memory updating). The cognitive tests are performed at the baseline, 3-month, and 6-month stages and the BRIEF-A is performed at the baseline, 3-month, 6-month, and 18-month stages. Changes from baseline to each follow-up point (3-month / 6-month / 18-month) and between the follow-up points are evaluated.

Focused and Sustained Attention is assessed using the Sustained Attention to Response Task (SART) performed at the baseline, 3-month, and 6-month stages. Changes from baseline to each follow-up point (3-month / 6-month) and between the follow-up points are evaluated.

Verbal Working Memory and Learning are assessed using the Digit Span subtest of the Wechsler Adult Intelligence Scale IV (WAIS-IV) and the Word List I & II subtests of the Wechsler Memory Scale III (WMS-III) performed at the baseline, 3-month, and 6-month stages. Changes from baseline to each follow-up point (3-month / 6-month) and between the follow-up points are evaluated.

Verbal and Non-Verbal Reasoning are assessed using the Similarities and Block Design subtests of the Wechsler Adult Intelligence Scale IV (WAIS-IV) performed at the baseline, 3-month, and 6-month stages. Changes from baseline to each follow-up point (3-month / 6-month) and between the follow-up points are evaluated.

Upper-Extremity Motor Functions are assessed using the Purdue Pegboard Test (PPT, measure of fine and gross motor dexterity and coordination), the Action Research Arm Test (ARAT, measure of fine and gross upper limb functioning), and the Box and Block Test (BBT, measure of unilateral manual dexterity) performed at the baseline, 3-month, and 6-month stages. Changes from baseline to each follow-up point (3-month / 6-month) and between follow-up points are evaluated.

Depression is assessed using the Beck Depression Inventory II (BDI-II, self-report version) questionnaire performed at the baseline, 3-month, 6-month, and 18-month stages. Changes from baseline to each follow-up point (3-month / 6-month / 18-month) and between the follow-up points are evaluated.

Quality of Life is assessed using the Quality of Life after Brain Injury (QOLIBRI, both self-report and informant-report versions) questionnaire performed at the baseline, 3-month, 6-month, and 18-month stages. Changes from baseline to each follow-up point (3-month / 6-month / 18-month) and between the follow-up points are evaluated.

Emotional Well-being of Family Members is assessed using the General Health Questionnaire (GHQ) and the Modified Caregiver Appraisal Scale (MPAI) given to the family member of the patient at the baseline, 3-month, 6-month, and 18-month stages. Changes from baseline to each follow-up point (3-month / 6-month / 18-month) and between the follow-up points are evaluated.

Structural and Functional Neuroplasticity is measured using structural and functional magnetic resonance imaging (MRI/fMRI) scanning performed at the baseline, 3-month, and 6-month stages. Overall, the purpose of the MRI/fMRI is to determine the exact location and size of the lesions and other pathological changes caused by the TBI and to study the changes in grey matter volume (using voxel-based morphometry, VBM), white matter volume and organization (using diffusion tensor imaging, DTI), and auditory-motor activity and connectivity (using fMRI) that take place in different brain areas during the 6-month follow-up and to correlate these changes to behavioral recovery. Changes from baseline to each follow-up point (3-month / 6-month) and between the follow-up points are studied.
