Evaluation of the Keeogo™ Dermoskeleton

Area of Science:

• Rehabilitation Engineering
• Neuroscience
• Biomechanics

Background:

• Mobility impairments due to neurological conditions significantly impact daily living.
• Dermoskeletons offer potential assistance for individuals with such impairments.
• Identifying suitable candidates and quantifying device benefits is crucial for effective rehabilitation.

Purpose of the Study:

• To identify functional characteristics predicting successful use of the Keeogo™ dermoskeleton.
• To quantify the functional benefits provided by the Keeogo™ dermoskeleton to users.
• To explore the impact of the dermoskeleton on specific mobility and daily living tasks.

Main Methods:

• Recruited thirteen individuals with neurological mobility impairments.
• Assessed baseline function using Berg Balance Scale (BBS) and Timed Up and Go (TUG) tests.
• Evaluated walking performance (6-min walk test, 25-foot walk test) with and without Keeogo™.
• Analyzed a chronic stroke survivor's performance on stair climb, chair stand, and sit-to-stand tasks with and without the device, including muscle activity and kinetics.

Main Results:

• Successful Keeogo™ users demonstrated moderate functional levels (BBS: 46-51s, TUG: 8-12s).
• The dermoskeleton enhanced performance in stair climbing and chair stand tests.
• A stroke survivor showed improved motor control, kinetics, and postural control during sit-to-stand tasks when using Keeogo™.

Conclusions:

• This study provides initial data to identify individuals with neurological impairments who may benefit from Keeogo™.
• The Keeogo™ dermoskeleton offers functional benefits including improved walking, endurance, and performance in activities of daily living.
• Moderately impaired individuals show the greatest potential for benefiting from this assistive device.
