A client with progressive multiple sclerosis reports that their powered mobility device performance worsens significantly on warm days. Which feature should the CMC prioritize when recommending a replacement device?
Answer: Increased battery capacity
While heat affects MS symptoms, increased battery capacity ensures the power wheelchair maintains consistent performance through a full day without voltage drops that worsen with heat-related fatigue.
According to ADA standards, what is the minimum required clear floor space for a forward approach to an accessible reach range control or operating mechanism?
Answer: 30 inches by 48 inches
ADA Standards for Accessible Design require a minimum 30-inch by 48-inch clear floor space for a forward approach to reach range elements.
A client who is deaf-blind requires an AAC system. Which output modality is specifically designed for individuals with this dual sensory impairment?
Answer: Refreshable Braille display
A refreshable Braille display converts digital text to tactile Braille output, making it accessible for individuals who are deaf-blind.
Which seating intervention is specifically indicated to redistribute pressure away from bony prominences and reduce the risk of pressure injuries in a wheelchair user?
Answer: Contoured foam cushion with pressure-mapping optimization
A contoured foam cushion, especially when fitted using pressure-mapping technology, redistributes interface pressure away from ischial tuberosities and coccyx to reduce pressure injury risk.
A CMC is evaluating vehicle modifications for a client who drives from their power wheelchair. Which securement system is the current industry standard for wheelchair-occupied vehicle transport?
Answer: Four-point strap tie-down with separate occupant restraint
The four-point strap tie-down system with a separate, vehicle-anchored occupant restraint (lap and shoulder belt) is the ANSI/RESNA standard for occupied wheelchair securement.
A client with ALS in early stages presents for AT evaluation. Why is early intervention particularly critical for AAC planning in this population?
Answer: Early voice banking preserves natural speech characteristics before dysarthria progresses
Voice banking during the early stages of ALS allows the client to record natural speech for use in speech-generating devices before dysarthria advances and voice quality deteriorates.
Which type of adaptive switch is activated by detecting muscle movement or skin surface EMG signals, making it appropriate for clients with very limited but consistent muscle activity?
Answer: Electromyography (EMG) switch
An EMG switch detects electrical signals generated by even minimal muscle contractions, enabling clients with very restricted motor function to activate assistive technology.
