Investigative and Usability Findings of the Move-D Orthotic Brace Prototype for Upper Extremity Tremors in Pediatric Patients: An Unblinded, Experimental Study

Tremors affect pediatric and adult populations, with roughly 3% of people worldwide experiencing essential tremors. Treatments include medication, deep brain stimulation, occupational/physical therapy, or adaptive equipment. This unblinded experimental pre-test–post-test study was performed (April–September 2021) at Children’s Health Orange County, evaluating the effectiveness Move-D, a novel orthotic brace, on Ten participants (14–19 years old) upper extremity tremors (5 essential, 2 dystonic, 1 coarse, postural, unspecified) were enrolled. Participants completed usability survey performance measured utilizing Bruininks–Oseretsky Test Motor Proficiency, second edition, without using one-sided t-tests mean differences. Move-D improved age-equivalent scores for fine motor precision by 20.5 months limb coordination 15.1 months. Manual percentile rankings increased 2.9%. dexterity unaffected. The revealed that 7/10 agreed strongly they could move their arm freely while wearing brace reduced tremors, felt comfortable home. Through standardized testing findings from survey, showed an improvement functional abilities in population
