A system for operating a traction device to detect blood flow patterns for intraneural facilitation, the system comprising: one or more processors; one or more traction devices to control traction, by the one or more processors, so as to position a subject in one or more positions when positioned on one or more areas of the subject; one or more probes connected to the one or more processors to supply signals when applied to one or more areas of the subject; and one or more memory devices in communication with the one or more processors and including instructions that, when executed by the one or more processors, cause the system to: receive first signals from the probe when the probe is positioned at the first area of the subject and when the traction device is positioned in a first position; process the received first signals to provide a first display of a first 2D flow pattern measuring blood flow when being supplied from a first artery to a second artery supplying the blood flow to one or more nerves of the subject; move the traction device to a second position based at least in part on the determined first 2D flow pattern, thereby to control the blood flow for a first predetermined period of time; receive second signals from the probe when the probe is positioned at one or more second areas of the subject and when the traction device is positioned in the second position thereby to control the blood flow for a first predetermined period of time; process the received second signals to provide a second display of a second 2D flow pattern measuring the blood flow from the first artery to the second artery; and compare the first 2D flow pattern and the second 2D flow pattern to determine a first change in the blood flow through the second artery, thereby to provide vascular changes in the subject via INF. one or more processors; one or more traction devices to control traction, by the one or more processors, so as to position a subject in one or more positions when positioned on one or more areas of the subject; one or more probes connected to the one or more processors to supply signals when applied to one or more areas of the subject; and one or more memory devices in communication with the one or more processors and including instructions that, when executed by the one or more processors, cause the system to: receive first signals from the probe when the probe is positioned at the first area of the subject and when the traction device is positioned in a first position; process the received first signals to provide a first display of a first 2D flow pattern measuring blood flow when being supplied from a first artery to a second artery supplying the blood flow to one or more nerves of the subject; move the traction device to a second position based at least in part on the determined first 2D flow pattern, thereby to control the blood flow for a first predetermined period of time; receive second signals from the probe when the probe is positioned at one or more second areas of the subject and when the traction device is positioned in the second position thereby to control the blood flow for a first predetermined period of time; process the received second signals to provide a second display of a second 2D flow pattern measuring the blood flow from the first artery to the second artery; and compare the first 2D flow pattern and the second 2D flow pattern to determine a first change in the blood flow through the second artery, thereby to provide vascular changes in the subject via INF. receive first signals from the probe when the probe is positioned at the first area of the subject and when the traction device is positioned in a first position; process the received first signals to provide a first display of a first 2D flow pattern measuring blood flow when being supplied from a first artery to a second artery supplying the blood flow to one or more nerves of the subject; move the traction device to a second position based at least in part on the determined first 2D flow pattern, thereby to control the blood flow for a first predetermined period of time; receive second signals from the probe when the probe is positioned at one or more second areas of the subject and when the traction device is positioned in the second position thereby to control the blood flow for a first predetermined period of time; process the received second signals to provide a second display of a second 2D flow pattern measuring the blood flow from the first artery to the second artery; and compare the first 2D flow pattern and the second 2D flow pattern to determine a first change in the blood flow through the second artery, thereby to provide vascular changes in the subject via INF.
