Powered Mobility Manual - Cerebral Palsy Alliance

PRESCRIPTION | 5Controller / input device(alternate control)The important point is to ensure that the inputdevice, e.g. head array, is compatible with the controlsystem. This will be the case with demo systemstrialled, but the issue may arise when the poweredwheelchair and controller are chosen from differentsuppliers or ranges. Incompatibility would mean anexpensive error.ProgrammabilityAsk the supplier what can be altered and reprogrammedusing the controller itself vs. a handheldprogrammer vs. computer program. Access tothese programmes may be useful to the therapistinvolved in skill development work with the useror to a user in an isolated community. It may bedetrimental where others are able to alter andchange settings, e.g. children. Choices should bebased on individual need.Attendant controlDoes the carer need the control all the time or onlypart of the time? Is height and location of the controllerat the rear suitable for the carer or does it need to beadjustable for many? Does it need to be on the left orthe right?TransportCheck access, check clearance on hoist or ramp,check tie-downs or locking plates are compatiblewith powered wheelchair. Consider replacementsinto the future, check with supplier where these aresupplied.Battery chargeCheck with the supplier how often and how long thebatteries need to be charged. Retain instructionsprovided and follow routinely to ensure maximumbattery life and distance is achieved. Check withsupplier how far the battery should take the userbefore needing a recharge.Top speedTop speed is a point of comparison betweenpowered wheelchairs. However, according tothe RTA, to be able to use the wheelchair in anycommunity area, the speed must be under 10km/h.Compatibility with other assistivetechnologyCheck which other assistive technology equipmentis used and whether it needs to be interfaced(electronically connected to function together) orjust integrated into the same space as each otherand operated independently. See Section 9.2 oninterfacing for more information.Warranty periodThis should be recorded as it will be important forrepairing any fault that occurs.Tracking of equipmentIt is important to Cerebral Palsy Alliance that anyequipment prescribed can be tracked by the supplierin the event of a product recall, as some faults maycause injury if not addressed.Access to spare partsIt is of great benefit if the supplier has a servicedepartment available to offer specific parts, repairsand maintenance because powered wheelchairsneed to be well maintained for safety.Individual requirementsColour may not seem important but can besignificantly interwoven with a person’s self image,self-esteem and their acceptance of the equipment.It is important to discuss and include some ofthe more individual requirements for features toassist with self-care, work or leisure activities, likea cup holder, sports tyres, fishing rod holder or akeyboard support. Where possible these shouldbe accommodated to provide greater access andindependence in daily life.5.2.1 Performance Analysis -based on drive wheel locationThe following Performance Analysis tables weresourced from the International Seating Symposiumof 2005. The information is complex but useful whenfaced with the need to make a decision regardingdrive wheel location. For guidance, contact a seniortherapist or product supplier.The tables below rate indoor and outdoorperformance of powered wheelchairs, based on drivewheel location. A number of other factors can affectwheelchair performance, including power, powerdelivery and individual characteristics such as buildand ability of the user. Consider these in addition tothe information presented below. This informationwas sourced from ‘Power Wheelchairs A NewDefinition’, G.F.
