DESIGN AND DEVELOPMENT OF AN ADJUSTABLE DYNAMIC HAND SPLINT
Journal Title: Engineering and Technology Journal - Year 2022, Vol 7, Issue 09
Abstract
Introduction: Radial nerve injury is comparatively a common occurrence. Recovery, however, depends on the level of injury. Medication, rest and surgery are among treatment regime, although, Orthotic splints are frequently used in its management to compensate for failure of motor power. The aim of this study was to modify existing design and fabricate an adjustable Dynamic Hand Splint utilizing locally sourced materials for the management of radial nerve palsy. Materials and Mathods: Autodesk Revit software and the cast of a patient were used for both the schematic designs and to obtain the measurements for the device. The cast was transferred to the lamination jig were it was moulded with EVA foam (ethylene vinyl acetate) under heat from electric oven, epoxy resin was also applied all over the EVA foam and the plastic lamination, fibre glass and stockinet was done. The final product was able to fit optimally on patients with varying circumferences and could be used for both the left and right sides of the upper extremities. Discussion: The mean of maximum active flexion was 98.70 this is within the range of standard maximum flexion and gives an idea of the quantity of rehabilitative force our device generates when the patient pushes the spring and its efficiency. Conclusion: The splint was used on 5 subjects, the angle of extension in degrees obtained at normal wrist when at rest and measured with a goniometer range from 300 to 350 with mean of 32.60 while the maximum Active Flexion range from 950 with a maximum finger flexion of 1000.
