A diagnosis system for the spinal column nerve damaged patients
1Department of Biomedical Engineering, Inje University, Kimhae, 621-749 Korea.
Summary
Detecting spinal column nerve damage is challenging, as visible signs appear in only 14% of patients. This study explores using a humidity sensor array to identify damaged autonomic nerves by measuring sweat response to bladder pressure.
Area of Science:
- Neurology
- Biomedical Engineering
- Sensor Technology
Background:
- Spinal column damage is often not visibly apparent, with only 14% of patients showing clear signs.
- Accurate localization of spinal column autonomic nerve damage is crucial for effective treatment.
Purpose of the Study:
- To investigate the efficacy of a humidity sensor array for detecting spinal column autonomic nerve damage.
- To correlate sweat response, induced by urinary bladder pressure, with specific damaged nerve regions.
Main Methods:
- A humidity sensor array (HDP-05) was attached to pre-assigned regions along the patient's spinal column nerves.
- Sweating was induced by applying pressure to the urinary bladder.
- Humidity values were measured to identify potentially damaged autonomic nerve regions.
Main Results:
- Humidity sensor readings showed potential for differentiating between normal and damaged spinal column autonomic nerve regions.
- A challenge was observed where some damaged regions exhibited similar humidity values to normal regions.
Conclusions:
- Humidity sensing presents a potential, non-invasive method for assessing spinal column autonomic nerve integrity.
- Improvements in sensor attachment methods and sensor sensitivity are needed for enhanced diagnostic precision.

01:26Spinal Cord
The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.
01:23Spinal Nerves: Anatomy
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...

01:54The Spinal Cord
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.
01:14Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
01:15Spinal Cord: Gross Anatomy
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...
01:10Spinal Cord: Information Processing
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...
