Neurologic music therapy combined with EEG-tDCS for upper motor extremity performance in patients with corticobasal syndrome: Study protocol for a novel approach.

BACKGROUND: Corticobasal syndrome (CBS) is an atypical parkinsonian disorder that involves degeneration of brain regions associated with motor coordination and sensory processing. Combining transcranial direct current stimulation (tDCS) with rehabilitation training has been shown to improve upper-limb performance in other disease models. Here, we describe the protocol investigating whether tDCS with neurologic music therapy (NMT) (patterned sensory enhancement and therapeutic instrumental music performance) enhances functional arm/hand performance in individuals with CBS. METHODS: Study participants are randomly assigned to six 30-min sessions (twice per week for 3 weeks) of NMT + either sham tDCS or active tDCS. We aim to stimulate the frontoparietal cortex, which is associated with movement execution/coordination and sensory processing. The hemisphere contralateral to the more affected arm is stimulated (total stimulation current of 2 mA from 5 dime-sized electrodes). Individualized NMT sessions designed to exercise the upper limb are provided. Participants undergo gross/fine motor, cognitive and emotional assessments at baseline and follow-up (one month after the final session). To investigate the immediate effects of tDCS and NMT training, gross /fine motor, affective level, and kinematic parameter measurements using motion sensors are collected before and after each session. Electroencephalography is used to collect electrical neurophysiological responses before, during, and after tDCS+NMT sessions. The study participants, neurologic music therapist and outcome assessor are blinded to whether participants are in the sham or active tDCS group. CONCLUSION: This noninvasive and patient-centered clinical trial for CBS may provide insight into rehabilitation options that are sorely lacking in this population.

Music Listening as a Postanesthesia Care Unit (PACU) Nursing Intervention for Laparoscopic Radical Prostatectomy Patients: A Randomized Comparative Clinical Trial.

PURPOSE: Randomized comparative mixed method approach with qualitative inquiry study's aim sought to determine if there was a difference in pre/post-intervention State-Trait Anxiety Inventory (STAI) scores and postanesthesia pain scores between two music listening groups of laparoscopic radical prostatectomy patients. DESIGN: Prospective randomized comparative mixed method approach with a qualitative inquiry. METHODS: Sample size of 77 male participants assigned by a table of random numbers to Spotify patient-preferred music selection Group I (n = 37) or minimalist hypnotic music with guided relaxation breathing (MHMGRB) instructional narrative Group II (n = 40). Outcome measures used patients' STAI questionnaire and reported PACU admission and discharge pain scores. RESULTS: Both Groups I and II had reduced pain scores at discharge as compared to admission; both groups had a significant reduction (P = .046 Group I, and Group II (P = .002), but changes for comparative groups (I and II) were not significant between the two groups (P = .53). CONCLUSIONS: Study revealed that both patient-preferred selected music and MHMGRB can meaningfully reduce patients' anxiety and PACU pain scores.

Scrambler Therapy for the Treatment of Multiple System Atrophy-Parkinsonian Subtype Pain: A Case Report.

The management of pain in patients with multiple system atrophy (MSA) is often inadequate, and treatments commonly result in adverse effects. A 63-year-old man with the parkinsonian subtype of MSA presented with bilateral neck, shoulder, upper extremity, lower extremity, and low back pain of 6 years' duration. His baseline pain was 5 of 10 with flares to 10 of 10. After 4 35-minute scrambler therapy (ST) treatments, his pain was reduced to 0 of 10. His pain relief after 4 ST sessions lasted for 6 weeks. No complications or adverse effects occurred. ST deserves further study for patients with atypical parkinsonism.

Music Therapy and Music-Based Interventions for Movement Disorders.

PURPOSE OF REVIEW: There is emerging evidence that music therapy and other methods using music and rhythm may meaningfully improve a broad range of symptoms in neurological and non-neurological disorders. This review highlights the findings of recent studies utilizing music and rhythm-based interventions for gait impairment, other motor symptoms, and non-motor symptoms in Parkinson disease (PD) and other movement disorders. Limitations of current studies as well as future research directions are discussed. RECENT FINDINGS: Multiple studies have demonstrated short-term benefits of rhythmic auditory stimulation on gait parameters including gait freezing in PD, with recent studies indicating that it may reduce falls. Demonstration of benefits for gait in both dopaminergic "on" and "off" states suggests that this intervention can be a valuable addition to the current armamentarium of PD therapies. There is also emerging evidence of motor and non-motor benefits from group dancing, singing, and instrumental music performance in PD. Preliminary evidence for music therapy and music-based interventions in movement disorders other than PD (such as Huntington disease, Tourette syndrome, and progressive supranuclear palsy) is limited but promising. Music therapy and other music and rhythm-based interventions may offer a range of symptomatic benefits to patients with PD and other movement disorders. Studies investigating the potential mechanisms of music's effects and well-controlled multicenter trials of these interventions are urgently needed.

Macular pigment and lutein supplementation in ABCA4-associated retinal degenerations.

PURPOSE: To determine macular pigment (MP) optical density (OD) in patients with ABCA4-associated retinal degenerations (ABCA4-RD) and the response of MP and vision to supplementation with lutein. METHODS: Patients with Stargardt disease or cone-rod dystrophy and known or suspected disease-causing mutations in the ABCA4 gene were included. All patients had foveal fixation. MPOD profiles were measured with heterochromatic flicker photometry. Serum carotenoids, visual acuity, foveal sensitivity, and retinal thickness were quantified. Changes in MPOD and central vision were determined in a subset of patients receiving oral supplementation with lutein for 6 months. RESULTS: MPOD in patients ranged from normal to markedly abnormal. As a group, patients with ABCA4-RD had reduced foveal MPOD, and there was a strong correlation with retinal thickness. Average foveal tissue concentration of MP, estimated by dividing MPOD by retinal thickness, was normal in patients, whereas serum concentration of lutein and zeaxanthin was significantly lower than normal. After oral lutein supplementation for 6 months, 91% of the patients showed significant increases in serum lutein, and 63% of the patients' eyes showed a significant augmentation in MPOD. The retinal responders tended to be female and to have lower serum lutein and zeaxanthin, lower MPOD, and greater retinal thickness at baseline. Responding eyes had significantly lower baseline MP concentration than did nonresponding eyes. Central vision was unchanged after the period of supplementation. CONCLUSIONS: MP is strongly affected by the stage of ABCA4 disease leading to abnormal foveal architecture. MP could be augmented by supplemental lutein in some patients. There was no change in central vision after 6 months of lutein supplementation. Long-term influences of this supplement on the natural history of these macular degenerations require further study.
