Abstract
A method for assessing and reversing exercise impairment in adults having peripheral vascular disease includes quantifying a musculoskeletal deoxygenation level (MDL) of a human subject provided by a wearable near infrared spectroscopy system configured to measure the deoxygenation level during exercise, comparing the quantified MDL to a range of pre-determined healthy MDL values for the subject, and, if the quantified MDL is outside of the pre-determined target MDL values, determining a corrective exercise intensity level or ‘dose’ effective to bring the MDL of the subject within the target MDL values and reverse the exercise impairment.
Core Innovation
The invention relates to an EXERT platform and a method for assessing and reversing exercise impairment in adults having peripheral vascular disease. The method quantifies a musculoskeletal deoxygenation level (MDL) of a human subject using a wearable near infrared spectroscopy system configured to measure the deoxygenation level during exercise, and compares the quantified MDL to a range of pre-determined healthy MDL values for the subject.
When the quantified MDL is outside the range of pre-determined healthy MDL values, the method determines a corrective exercise intensity level effective to bring the subject’s MDL within the pre-determined healthy MDL values and reverse the exercise impairment. The method instructs the human subject to increase or decrease an exercise intensity level, or to change to a different exercise when the quantified MDL is outside the range.
The human subject has a chronic disease, and the determination of the range of pre-determined healthy MDL values is customized based upon the chronic disease. The platform stores reference MDL values in an electronic database and uses a processor to compare with the quantified MDL and generate comparison/control outputs.
The described system includes wearable hardware and wireless transfer of the measured deoxygenation level to remote guidance, including a remote receiver and an electronic device with a digital dashboard or trainer. The wearable near-infrared spectroscopy system includes an infrared light source and a detector arranged to receive infrared light after it passes through selected skin tissue, and is optionally implemented with one or more physiological sensors.
Claims Coverage
The document provides two independent claims covering a method to assess and reverse exercise impairment using wearable near infrared spectroscopy quantified musculoskeletal deoxygenation level (MDL), with corrective exercise instruction based on comparison to pre-determined healthy MDL ranges customized for chronic disease. Each independent claim contains multiple inventive features that address measurement during exercise, subject-specific comparison, corrective exercise determination, and chronic-disease customization; one independent claim further covers instructing change to a different exercise.
Wearable near infrared spectroscopy quantifying musculoskeletal deoxygenation level during exercise
Quantifying a musculoskeletal deoxygenation level (MDL) of a human subject provided by a wearable near infrared spectroscopy system configured to measure said deoxygenation level during exercise.
Comparing quantified MDL to pre-determined healthy MDL range
Comparing said quantified MDL to a range of pre-determined healthy MDL values for said subject.
Corrective exercise intensity to bring MDL within healthy MDL range and reverse impairment
If said quantified MDL is outside of said range of pre-determined healthy MDL values, determining a corrective exercise intensity level effective to bring said MDL of said subject within said range of pre-determined healthy MDL values and reverse said exercise impairment.
Instructing increase or decrease of exercise intensity
Instructing said human subject to increase or decrease an exercise intensity level.
Customization of healthy MDL range based on chronic disease
Wherein said human subject has a chronic disease, and wherein a determination of said range of pre-determined healthy MDL values are customized based upon said chronic disease of said human subject.
Instructing change to a different exercise when MDL is outside range
Instructing said human subject to change to a different exercise if said quantified MDL value is outside of said range of pre-determined healthy MDL values.
Across the independent claims, the core coverage is a closed-loop assessment-and-response method: wearable near-infrared spectroscopy quantifies musculoskeletal deoxygenation level during exercise, the quantified MDL is compared to a pre-determined healthy MDL range that is customized based on chronic disease, and when outside the range a corrective exercise intensity and, in one independent claim, a different exercise, is determined and used to reverse exercise impairment.
Stated Advantages
Allows assessing and reversing exercise impairment in adults having peripheral vascular disease by bringing a subject’s MDL within pre-determined healthy MDL values.
Provides customized healthy MDL ranges based on chronic disease.
Documented Applications
Assessing and reversing exercise impairment in adults having peripheral vascular disease during exercise using wearable near infrared spectroscopy quantified musculoskeletal deoxygenation level (MDL).
