Abstract

By the year 2050, it is expected that 3.6 million people will have upper limb amputations. Despite the increase in functionality provided by prostheses, a recent study found that 45% of children with upper limb deficiencies reject their prosthetic device. Training paradigms for acquired amputees and stroke survivors focus on interlimb transfer paradigms to transfer motor repertoires from the non-affected limb to the affected limb, consequently, increasing the use of the affected limb in day-to-day life. Thus, the purpose of this study is to assess the temporal synchrony of hand movement during a reaching task and gross manual dexterity after completing an 8-week home intervention. We hypothesized that bimanual coordination will be more synchronous and there will be an increase in unilateral gross manual dexterity after the completion of 8-week home intervention. The research subjects were given a 3D printed prosthesis which was designed and scaled to be as proportional and symmetric to the length and circumference of the participant’s non-affected limb. Box and Block and bimanual coordination assessments were performed at baseline and three months after the start of the study. Six subjects were given instructions to practice using their prosthetic at home for two hours a week while five were enrolled in an 8-week home intervention program. The home interventions consisted of two virtual-home visits per week where a training protocol was administered. The 8-week intervention program will ensure repetition of reaching movements and will create better outcomes in bimanual and gross manual dexterity motor assessments.
