US 12,708,290 B2 · Asymmetrical rhythmic auditory cueing based gait modification

Abstract

A method, apparatus, or system for modifying and assessing gait asymmetry is disclosed. The method, apparatus, or system may include measuring a first baseline step time for a first leg of an individual and a second baseline step time for a second leg of the individual and determining a first target step time for the first leg and a second target step time for the second leg. The first target step time can be different from the second target step time. The method may further include generating a series of auditory cues comprising a first cue duration corresponding to the first target step time and a second cue duration corresponding to the second target step time for synchronizing the first baseline step time and the second baseline step time with the first target step time and the second target step time, respectively. Other aspects, embodiments, and features are also claimed and described.

Dependent claims

A method for treating gait asymmetry of a patient having asymmetric gait impairment comprising:

measuring a first baseline step time for a first leg of the patient and a second baseline step time for a second leg of the patient, the first baseline step time being shorter than the second baseline step time;
determining an asymmetrical rhythm tolerance for the patient;
determining a first target step time for the first leg and a second target step time for the second leg, the first target step time being different from the second target step time at a first time;
generating a series of auditory cues based on the asymmetrical rhythm tolerance, the series of auditory cues comprising interleaved first cues for the first leg and second cues for the second leg and having:
a first cue cadence based on the first baseline step time and the first target step time, and
a second cue cadence, different from the first cue cadence, based on the second baseline step time and the second target step time;
administering the series of auditory cues to the patient;
measuring patient gait data responsive to the patient walking in accordance with the series of auditory cues;
and
monitoring the patient gait data.
