Assistive devices and adaptive technology play a critical role in maintaining independence and safety in corticobasal syndrome (CBS). As the disease progresses and functional abilities decline, appropriate selection and training with assistive devices can significantly extend the period of independent functioning and reduce caregiver burden. This page covers the range of assistive technologies available for individuals with CBS, organized by functional domain.

Overview

Unlike Parkinson's disease, where dopaminergic medications can maintain function for years, CBS shows minimal medication response, making assistive devices essential earlier in the disease course. The asymmetric presentation, cortical signs (apraxia, alien limb), and cognitive involvement create unique requirements for assistive technology selection[@niccolini2022].

The asymmetric presentation, cortical signs (apraxia, alien limb), and cognitive involvement create unique requirements for assistive technology selection[@niccolini2022].

Key considerations for CBS:

• Asymmetric function: Devices may be needed primarily for one side
• Apraxia: Requires simple, intuitive device designs
• Cognitive involvement: May limit ability to learn new technologies
• Rapid progression: Frequent reassessment needed
• Cortical sensory loss: Affects device use requiring tactile feedback

Mobility Devices

Canes and Walkers

Standard Canes

• Indicated for early disease with mild imbalance
• Standard quad cane provides wider base of support
• Specialty handles for reduced grip strength
• Height adjustment for proper elbow flexion

• Standard walker for moderate instability
• Two-wheeled (rolling) walker for shuffling gait
• Four-wheeled (rollator) for efficient ambulation
• Basket attachment for carrying items

• Asymmetric weakness favors unilateral support devices
• Cognitive impairment may limit walker use
• Apraxia may prevent proper walker navigation
• Environmental factors (stairs, narrow spaces)[@kelley2018mobility]

Wheelchairs

Manual Wheelchairs

• Appropriate when patient can self-propel
• Lightweight models preferred for caregiver transport

• Chin control for limited upper limb function
• Sip-and-puff for severe impairment
• Tilt-in-space for positioning

• Three-wheeled for indoor maneuverability
• Four-wheeled for outdoor stability
• Dismantling for vehicle transport
• Limited utility in CBS (upper limb weakness)

Evidence Summary

Assistive technology in CBS serves multiple functions:

The CBS-specific considerations (asymmetry, apraxia, cognitive involvement) require specialized assessment and device selection. Early intervention and regular reassessment optimize outcomes.
