Modified Graded Motor Imagery for Musicians' Focal Dystonia: A Case Series.

PURPOSE: This study aimed to assess the effectiveness of the "modified graded motor imagery" (mGMI) protocol as a rehabilitative treatment of musician's focal dystonia (MFD). METHODS: Six musicians with MFD (age 43.83±17.24 yrs) performed the home-based mGMI protocol (laterality training, imagined hand movements and visual mirror feedback) once a day for 4 weeks. The mMGI protocol was designed to sequentially activate cortical motor networks and improve cortical organization. Subjects were evaluated before and after treatment with the dystonia evaluation scale (DES), arm dystonia disability scale (ADDS), Tubiana-Chamagne scale (TCS), and performing scale (PS). RESULTS: All participants were compliant with the mGMI treatment protocol without any adverse events. A significant improvement was measured in ADDS (p=0.047) and TCS scores (p=0.014) but not in DES (p=0.157). The severity of MFD decreased from moderate to mild in four patients. After mGMI treatment, all musicians were able to play easy pieces (TCS: median 3.5, IR 3.5-4). CONCLUSION: The findings from this pilot study suggest that home-based mGMI treatment is a feasible and promising rehabilitative approach for patients with mild to moderate MFD.

Sensorimotor Perceptive Rehabilitation Integrated (SPRInt) program: exercises with augmented movement feedback associated to botulinum neurotoxin in idiopathic cervical dystonia-an observational study.

BACKGROUND: Idiopathic cervical dystonia (ICD) is a focal dystonia affecting neck muscles. Botulinum neurotoxin (BoNT) is the first-line treatment of ICD and different physical therapies (including exercise) are often proposed as adjunct treatments. However, the actual effectiveness of exercise in ICD is unclear. The aim of the current work is to assess the potential effectiveness of the Sensorimotor Perceptive Rehabilitation Integrated (SPRInt) exercise program as adjunct therapy for ICD. METHODS: Fifteen ICD patients received BoNT injections in the neck muscles and, 12 weeks later, received BoNT a second time and SPRInt started. SPRInt consists in 18 exercise sessions in which augmented feedback of movement (including visual and acoustic feedback) is extensively used. Dystonia burden was measured by the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS). Patients were evaluated immediately before, 6 and 12 weeks after each BoNT injection. RESULTS: Six weeks after the first BoNT injection (i.e., at BoNT peak effect), TWSTRS total score was better than baseline and remained improved at 12 weeks. TWSTRS disability domain slightly improved 6 weeks after the first BoNT injection, but after 6 more weeks returned to its baseline level. Disability improved more at SPRInt end (i.e., 6 weeks after the second BoNT injection), being even lower than after toxin alone. With a single-subject analysis, 4/10 patients who did not improve disability after BoNT improved after SPRInt plus BoNT. CONCLUSIONS: SPRInt plus BoNT can be more effective than BoNT alone in improving cervical dystonia patients' difficulties in the activities of daily living.

Single-case study in rehabilitation with SaM method (Sense and Mind): a proposal and analysis.

OBJECTIVE: The aim of the present case report is to describe a new rehabilitation approach for traumatic brain injury (TBI). BACKGROUND: TBI is a heterogeneous disorder that could be associated with cognitive and behavioral impairments. The clinical complexity of TBI patients requires a specialized and integrated approach that involves several rehabilitation experts (Mazzucchi in La riabilitazione neuropsicologica, Elsevier-Masson, Milan, 2012). SaM method (SaMM) (Risoli in La riabilitazione spaziale, Carocci Faber, Rome, 2013) is a new rehabilitation approach based on "embodied cognition" theory (Gallese and Lakoff in Cogn Neuropsychol 22(3):455-479, 2005) and has the aim to improve spatial abilities through structured body exercises. MATERIALS AND METHODS: The patient was a 35-year-old male who had TBI 9 months before. The patient was evaluated, before and after the treatment, with neuropsychological tests (Rey Test copy and reproduction, Elithorn Test, Trail Making Test, Rey Auditory Verbal Learning Test), Lawton Index for IADL, level of cognitive functioning, and a qualitative process-oriented assessment with SaMM exercises. The patient was treated with SaMM for 4 months, three times a week. RESULTS: Several of the executed assessments showed an improvement after SaMM treatment. The patient also reported amelioration in some daily activities such as swimming and using phone and money. DISCUSSION: Further investigations are necessary, but the SaMM appeared to be a useful complementary restitutive approach for TBI patients.

The Technical Ability and Performing Scale (TAPS): A newly developed patient-reported functional rating scale for Musician's focal dystonia.

BACKGROUND: Musician's Focal Dystonia (MFD) is the most common adult-onset dystonia involving the hand and can cause a professional music career to end. MFD affects about 1% of professional musicians and is a challenging clinical condition to treat. This work aimed to validate the Technical Ability and Performing Scale (TAPS), a newly-developed patient-reported functional rating scale for the clinical assessment of the MFD burden. METHODS: Seventy-seven musicians with MFD (40.84 ± 13.14 years) who accessed "Sol Diesis Service" were consecutively enrolled. Each subject filled in the TAPS after playing six technical passages of different complexity for 45 s each. The clinicians also collected the Arm Dystonia Disability Scale (ADDS) and Tubiana-Chamagne Scale (TCS). Cronbach's α coefficient was used to assess reliability; concurrent validity was measured using correlation with validated tools (ADDS and TCS). RESULTS: Our results showed that the symptoms of dystonia appeared at around 33 years of age and lasted for at least three years. The Cronbach's α displayed good internal consistency (0.817) for Technical Ability (TA). The two TAPS scores, TA and Performing Score (PS), positively correlated with TCS total score and negatively with ADDS total score (concurrent validity). CONCLUSIONS: The TAPS is a reliable and valid tool for the clinical assessment of the MFD burden. This patient-reported outcome measure may facilitate patient engagement in decision-making about their care and can help healthcare professionals to monitor the musician's change during the rehabilitative intervention.
