Staged magnetic resonance-guided focused ultrasound thalamotomy for the treatment of bilateral essential tremor and Parkinson's disease related tremor: a systematic review and critical appraisal of current knowledge.

Introduction: Essential tremor (ET) and Parkinson's Disease (PD) are debilitating neurodegenerative disorders characterized by tremor as a predominant symptom, significantly impacting patients' quality of life. Magnetic Resonance-guided Focused Ultrasound (MRgFUS) Thalamotomy is an innovative therapeutic option for the treatment of unilateral medically refractory tremor with fewer adverse effects compared to traditional surgical interventions. A recent CE approval allows appropriate patients to have their second side treated. Objective: The objective of this systematic review was to analyze available current knowledge about the use of MRgFUS for the treatment of bilateral ET and PD related tremor, to identify the effectiveness and the risks associated with bilateral treatment. Methods: Eligible studies were identified by searching published studies in PubMed and Scopus databases from May 2014 to January 2024 and by identifying ongoing studies registered on the clinicaltrials.gov website. Data were summarized by considering the following information topics: the number of patients involved, the selected lesion target, the assessment tool used to evaluate clinical changes, the observed improvement, the reported side effects, and the time interval between the two treatments. The study was registered in PROSPERO (ID: CRD42024513178). Results: Nine studies were eligible for this review, 7 for ET and 2 for PD. The involved population included a variable number of patients, ranging from 1 to 11 subjects for ET and from 10 to 15 subjects for PD. The main lesional targets were the ventral intermediate nucleus of the thalamus, the pallidothalamic tract and the cerebellothalamic tract bilaterally. All studies investigated the tremor relief through the Clinical Rating Scale for Tremor (CRST) in patients with ET, and through the Unified Parkinson's Disease Rating Scale (UPDRS) in patients with PD. A variable degree of improvement was observed, with all patients expressing overall satisfaction with the bilateral treatment. Adverse events were mild and transient, primarily involving gait disturbances, dysarthria, and ataxia. A standardized protocol for administering the two consecutive treatments was not identifiable; typically, the timing of the second treatment was delayed by at least 6 months. Conclusion: Available evidence supports the effectiveness and safety of staged bilateral MRgFUS treatments for ET and PD-related tremor.

A novel manual therapy approach for managing acute interscapular pain following median sternotomy for open cardiac surgery: A clinical comparative analysis.

INTRODUCTION: Acute interscapular pain is a frequent postoperative complication observed in patients who have undergone median sternotomy. This study aimed to assess a novel approach to manual therapy utilizing the Regional Interdependence (RI) concept for managing interscapular pain in post-sternotomy patients. MATERIALS AND METHODS: In an observational study, a cohort of 60 consecutively admitted patients undergoing median sternotomy was enrolled. Data collection involved standardized clinical evaluations conducted at specific time points: prior to manual treatment (T0), following five manual treatments (T5), and at post-treatment days 10 (T10) and 30 (T30). The Experimental Group (EG) received manual treatment based on the RI concept, performed in a seated position to accommodate individual clinical conditions and surgical wound considerations. The Control Group (CG) received simulated treatment involving identical exercises to the EG but lacking the physiological or biomechanical stimulation. RESULTS: Among the initial 60 patients, 36 met the inclusion criteria, while 24 were excluded due to one or more exclusion criteria. Treatment outcomes revealed a statistically significant improvement in the EG compared to the CG, not only in terms of pain reduction but also in functional recovery and consequent disability reduction. DISCUSSION: The RI concept emerges as a potentially valuable therapeutic approach for addressing interscapular dysfunction, particularly in highly complex post-sternotomy patients. This study highlights the clinical relevance of the RI concept in the management of interscapular pain and highlights its potential utility in improving patient outcomes in the challenging context of sternotomy surgery.

Rehabilitation Interventions for Improving Balance in Parkinson's Disease: A Narrative Review.

INTRODUCTION: Postural instability is one of the latest clinical manifestations of Parkinson disease. Because of the limited therapeutic effect of pharmacological therapies, a favorable consideration has now become toward rehabilitation interventions. Thus, this study aimed to synthesize literature evidence to summarize the effects of rehabilitation interventions for improving balance in Parkinson disease. MATERIALS AND METHODS: We conducted a narrative review of randomized-controlled clinical trials comparing the effects of interventions, control interventions, and no interventions on balance-related outcomes. A comprehensive search using the MEDLINE database was conducted from January 2000 to September 2021. This review included the following causes of balance-related impairments: inability to control body weight in the base of support, impaired attention and focus on balance, postural deformities, proprioceptive deficiency, sensory-motor integration, and coordination disorders, including visual and auditory-motor coordination. RESULTS: Twenty randomized-controlled clinical trials were included in the review. Various balance-related outcomes were included. The included studies focused on the effectiveness of different rehabilitation interventions, including physical therapy, virtual reality and telerehabilitation, treadmill training, hydrotherapy, action observation training, balance and cues training interventions, and cognitive rehabilitation. CONCLUSIONS: The results suggest that most of the included rehabilitation interventions have promising therapeutic effects in improving balance in Parkinson disease.
