Recent advances in custom moulded seating, based on orthotic and prosthetic principles, have significantly expand the potential for custom seating applications across a broader range of needs, including for early custom seating interventions. Unique strategies for early custom seating interventions can successfully address mobility, function, and skin care in active and functional users. The session covers design of custom seats and back supports, the importance of optimal wheelchair configuration and seating interfaces – including the correct orientation of seating for a constructive relationship with gravity! It will also cover client assessment, simulation, tips for fitting, and strategies for documentation.
