Background: Stroke is one of the leading causes of disability worldwide, with low- and middle- income countries (LMICs) representing 69% of stroke incidence. Technology-based interventions offer potential for improving motor function and rehabilitation adherence; however, their impact in LMICs remains unknown.

Objective: To measure the efficacy of technological interventions compared to conventional physical rehabilitation in improving post- stroke upper limb motor function in LMICs.

Methods: We conducted a systematic review (PROSPERO registration: CRD42020213333) of randomized clinical trials (RCTs) from PubMed, Global Index Medicus, and Physiotherapy Evidence Databases. Studies included stroke survivors receiving technological interventions for upper limb rehabilitation. Effectiveness outcomes included upper limb motor function, performance for activities of daily living, and quality of life. A meta-analysis was performed using mean differences (MD) and 95% confidence intervals (95% CI). Risk of bias was assessed using the Cochrane Collaboration tool for RCTs.

Results: Fifty studies were included after the screening phase, comprising a total of 2646 participants. Nine technological interventions were evaluated, including: virtual reality (40%), robotics (22%), telerehabilitation (10%), among others. Meta-analysis showed significant effect of immersive virtual reality on upper limb function using the Fugl-Meyer Scale (MD 5.65; 95% CI 4.88 to 6.43) and on daily activity performance using the Functional Independence Measure (MD 4,82; 95% CI 2,45-7,19). A significant difference was also found between telerehabilitation and conventional therapy using the modified Barthel index (MD of 3.28; 95% CI 0.86 to 5.70).

Conclusions: Immersive virtual reality and telerehabilitation are effective interventions compared to conventional rehabilitation in LMICs.

Upper extremity injuries in baseball players demand advanced prevention. Our study analyzed clinical features using machine learning techniques to provide precise and individualized injury risk assessment and prediction. We recruited 98 baseball players and collected data on glenohumeral internal/external rotation, posterior capsule thickness, supraspinatus tendon thickness, acromiohumeral distance, and occupation ratio.

Background: Orthopaedic procedures often cause intense postoperative pain, posing challenges for effective management. Brachial plexus blocks offer relief but optimising analgesia with minimal local anaesthetic is still challenging. Perineural dexamethasone, with anti-inflammatory effects, shows promise in lower doses but lacks sufficient research.

Genome-Wide Scan of Fifth Finger Clinodactyly.

Mol Genet Genomic Med

March 2025

Center for Craniofacial and Dental Genetics, Department of Oral and Craniofacial Sciences, University of Pittsburgh, Pittsburgh, Pennsylvania, USA.

Background: Fifth finger clinodactyly describes the conspicuous curvature of the fifth digit toward the other digits of the hand. Phenotypic expression can range from mild and almost imperceptible to severe, where function is impacted, and clinical intervention may be required. Although classically considered an autosomal dominant trait based on early family studies, no genes have been mapped for the trait.

Case Series: Free vascularized costochondral grafts in upper extremity reconstruction.

Front Surg

February 2025

Department of Plastic, Reconstructive, Aesthetic and Hand Surgery, University Hospital Basel, Basel, Switzerland.

Introduction: Costochondral grafting is well-known reconstructive option for the temporomandibular joint. In the upper extremity, non-vascularized costochondral grafts have been used for radial head reconstruction, for osteoarthritis of the trapeziometacarpal joint and proximal pole reconstruction of the scaphoid. Evidence suggests that vascularization of bone grafts lead to a higher union rate and a faster time to union.

Rare multiple schwannomas of the left upper extremity: A case report.

Oncol Lett

April 2025

Department of Orthopedics, The First Clinical Medical College, Guangdong Medical University, Zhanjiang, Guangdong 524023, P.R. China.

Schwannomas are rare benign neoplasms originating from Schwann cells of peripheral nerve sheaths. The current study presents a distinctive case involving multiple schwannomas along the peripheral nerves of the left upper extremity. The patient exhibited multiple gradually enlarging subcutaneous masses distributed along the nerves of the left upper limb, without pain, neurological deficits or a positive Tinel's sign upon physical examination.
