contact with their means of access to the ECS through relative motion, otherwise
they are unable to make further movements independently or summon assistance
if required.
There are also technical aspects to EC of beds and chairs associated with the
connection to the motor set. This is now only undertaken using specific interface
leads or connection modules produced by the bed or chair manufacturer. In some
instances a replacement handset is required to retain all movement functions.
Appliance Control
As with beds/chairs, control of other appliances can introduce risks, which require
evaluation and explanation. Control of a heater or air conditioning unit can result in a
detrimental extreme temperature if the user loses contact with their means of access
or falls asleep.
Door entry control through EC can greatly enhance independence of living
and sense of autonomy over one’s own home. However, risks come from correctly
identifying visitors before allowing entry and from the security of the electrically
powered lock release. Door entry control is likely to be unsuitable for an individual
with cognitive, memory or personality disorder, which might result in them allowing
access inappropriately.
Position and Orientation Mounting of EC Equipment
The EC controller and some of the peripheral units are often carefully positioned
for the user to be able to view satisfactorily using stands and mounting equipment.
In particular, various mounting systems have been developed to allow EC and other
EAT units to be mounted onto wheelchairs, in which many EC users spend much of
their day. The modular systems allow a bespoke solution to meet the needs and usage
pattern of the individual. As a consequence, an individualised risk assessment is
required. This includes the user both understanding and accepting the responsibility
for any limitations of use.
Internet Access
A key functional goal of providing access to computer technologies is likely to be
access to the internet for web browsing, email, social media and applications.
There are inherent risks to the individual from various sources (e.g., malware,
viruses, inappropriate social contact, financial deception or extortions and viewing
inappropriate material). Prior to provision of equipment to allow this, it is necessary
to determine that the intended user comprehends and accepts the responsibility for
these risks and any limitation of use arising. This is often achieved with a prescriber/
user agreement.

Following on from the assessment which will have identified the need and some of
the steps to facilitate the solution, the specialist EC services will formulate a prescription
identifying the most appropriate technology solution. This will then be actioned, with
referrals and requests made to relevant organisations and services as needed prior to the
technology being issued.
