A spinal cord injury(SCI) is a complex and life-altering condition that occurs when there is damage to the spinal cord, resulting in a range of neurological impairments.
Incomplete spinal cord injuryrefers to cases where the spinal cord is partially damaged, leading to varying degrees of sensory and motor function loss.
This condition can have a profound impact on a person's life, requiring comprehensive medical care and rehabilitation. In this article, we'll delve into the causes, symptoms, and treatment options for incomplete spinal cord injury.
What Is An Incomplete Spinal Cord Injury?
Damage to the spinal cord that partly affects signal transmission between the brain and muscles is referred to as an incomplete spinal cord injury.
The spinal cord and peripheral nerves transmit messages between the brain and the body. Signals can no longer reach their intended destination when brain circuits that convey signals are disrupted.
As a consequence, motor impulses from the brain that initiate movement may be unable to reach locations below the level of spinal cord damage. Similarly, sensory impulses (signals that help the brain experience touch) from places below the degree of damage may be blocked. As a result of a spinal cord injury, people lose feeling and motor control below their level of damage.
Some neuronal circuits at the level of damage remain intact when a spinal cord injury is partial. As a consequence, people may retain some feeling and/or motor control in places where they have been injured.
A complete spinal cord injury occurs when all neuronal circuits at the level of damage are compromised. As a consequence, no sensory or motor functions survive below the degree of harm.
In general, the more spared brain pathways a person has after damage, the better their recovery prospects. The next section will go over some of the most prevalent causes of incomplete spinal cord injury.
Complete Vs. Incomplete Spinal Cord Injury
When others talk about your spinal cord injury, one of the terminology that you are likely to hear a lot is "complete" or "incomplete."
When the spinal cord sustains just partial damage, it is able to continue its normal function of sending and receiving signals to and from the brain. This is referred to as an incomplete injury. In addition, below the level of the damage, it is possible for there to be some feeling (even if it is mild) as well as movement.
An injury is considered to be complete when there is no longer any sensory or motor function below the level of the damage.
If there is no motor or sensory function below the wounded location, this does not necessarily indicate that there are no intact axons or nerves crossing the injury site; rather, it simply means that these structures are not working as they should as a consequence of the trauma.
"Complete" and "Incomplete" Spinal Cord Injuries
Classification Of Incomplete Spinal Cord Injuries
Incomplete spinal cord injuries may be caused by a wide variety of traumas. These many kinds of spinal injuries are often categorized according to where on the spinal cord was injured: the front, the middle, the back, or the side.
Central Cord Syndrome
An injury to the spinal cord's central nervous system, as the term suggests. In this situation, it is usual for victims to experience numbness and a lack of motor control in their lower extremities.
However, in contrast to leg weakness, arm weakness is more common after this kind of damage. With the help of counseling and occupational/physical therapy, some patients with this form of incomplete spinal cord injury may be able to recover some function.
Anterior Cord Syndrome
When the spinal cord is injured in its anterior portion, this is known as anterior cord syndrome. Touch, pain, and temperature perceptions are often hampered as a result. With rehabilitation, most people who suffer an anterior cord damage may regain some mobility.
Posterior Cord Syndrome
When the spinal cord is injured in its rear (or posterior). Typically associated with injuries sustained from impacts to the back. In spite of having impaired coordination, most people who have survived a back injury have decent posture, strong muscles, and relatively normal ranges of motion.
Cauda Equina Syndrome
Lesions in the cauda equine nerve roots (the lumbar spinal nerve bundle) often lead to cauda equina syndrome. Left untreated, cauda equina lesions may cause severe lower back pain, motor weakness, sensory loss, and even paralysis, as stated by the American Association of Neurological Surgeons (AANS).
If the lesions are treated, the patient won't have any more, more serious symptoms. Although there is no certainty of recovery from any spinal cord injury, early treatment may avoid irreversible damage.
Brown-Sequard Syndrome
Incomplete spinal cord injury that damage just one side of the spinal cord (known as Brown-Sequard syndrome) are asymmetrical in nature.
The most common outcomes of this form of spinal cord injury are paralysis of a single limb (usually the leg) or paralysis of both arms and legs on one side of the body, with corresponding alterations in pain and temperature sensitivity on the unaffected side.
One side of the body below the injury site may be rendered immobile or weak while the other side is mostly unaffected.
Causes Of Incomplete Spinal Cord Injury
Traumatic Accidents
Incomplete spinal cord injuries can occur as a result of traumatic accidents, such as car crashes, falls from heights, sports injuries, and workplace accidents. The force and impact from these incidents can damage the spinal cord's structure and function, leading to incomplete injury.
Falls
Falling from a significant height or experiencing a sudden impact can result in incomplete spinal cord injuries. The spine's vertebrae may compress or fracture, causing damage to the spinal cord and disrupting its communication with the brain.
Sports Injuries
High-impact sports, like football, rugby, and extreme sports, can expose individuals to the risk of incomplete spinal cord injuries. Collisions, tackles, and falls during these activities can lead to trauma to the spinal cord and subsequent damage.
Medical Conditions
Certain medical conditions, such as tumors, infections, and degenerative disorders of the spine, can contribute to incomplete spinal cord injuries. These conditions may cause pressure on the spinal cord or compromise its blood supply, resulting in impaired function.
Violent Acts
Acts of violence, including gunshot wounds, stabbings, and physical assaults, can lead to incomplete spinal cord injuries. The intentional force applied to the spinal cord can cause damage, leading to various degrees of impairment.
Diseases
Some diseases, like multiple sclerosis and transverse myelitis, affect the spinal cord's healthand function. Incomplete spinal cord injuries can occur if these diseases lead to inflammation, demyelination, or other structural damage.
Medical Procedures
In rare cases, medical procedures involving the spine, such as spinal surgeries or interventions, can result in incomplete spinal cord injuries due to complications or unforeseen outcomes.
Natural Disasters
Natural disasters like earthquakes or severe accidents can cause buildings and structures to collapse, leading to traumatic injuries, including incomplete spinal cord injuries, for those caught in the disaster.
Symptoms Of Incomplete Spinal Cord Injury
Symptoms of an incomplete spinal cord injury can vary widely based on the location and severity of the injury, as well as the individual's overall health.
In incomplete injuries, some level of sensory or motor function remains below the level of the injury. Here are some common symptoms associated with incomplete spinal cord injuries:
- Sensory Changes - Altered sensation such as tingling, numbness, or hypersensitivity below the injury site. Sensory loss or changes in temperature perception, touch, and pressure.
- Motor Function Changes - Muscle weakness or paralysis in specific muscle groups. Difficulty with coordinated movements and muscle control. Spasticity, which is a condition where muscles become stiff and may contract involuntarily.
- Loss of Reflexes - Reflexes may be diminished, exaggerated, or absent depending on the injury's location and severity.
- Pain - Neuropathic pain, which is characterized by shooting, burning, or stabbing sensations. Phantom pain, where pain is felt in an area that no longer has sensation due to the injury.
- Bladder and Bowel Dysfunction - Loss of bladder and bowel control, requiring catheterization or bowel management strategies. Increased risk of urinary tract infections and other related complications.
- Respiratory Issues - Depending on the level of injury, individuals might experience difficulty breathing, requiring assistance or interventions to maintain proper lung function.
- Sexual Dysfunction - Changes in sexual function, including reduced libido, erectile dysfunction, and difficulty achieving orgasm.
- Spasticity - Muscle stiffness, involuntary muscle contractions, and spasms that can impact mobility and comfort.
- Changes in Blood Pressure and Heart Rate - Blood pressure and heart rate regulation might be affected, leading to potential issues with orthostatic hypotension (a sudden drop in blood pressure upon standing).
- Autonomic Dysfunction - Changes in autonomic functions, such as temperature regulation, sweating, and digestion.
- Fatigue and Weakness - Individuals with incomplete spinal cord injuries may experience fatigue and weakness due to disrupted nerve pathways.
Treatment And Rehabilitation
Medical Stabilization
The immediate priority after an incomplete spinal cord injury is medical stabilization. This involves ensuring the patient's safety, assessing their overall condition, and addressing any life-threatening injuries. Stabilization can include immobilization of the spine to prevent further damage.
Surgery
In some cases, surgery may be necessary to address any fractures, dislocations, or compressions of the spine that resulted from the injury. Surgery can help relieve pressure on the spinal cord and stabilize the spine's structure.
Medications
Medications may be prescribed to manage pain, reduce inflammation, and prevent complications such as infections or blood clots. In cases of nerve damage, medications to manage neuropathic pain or muscle spasms may also be prescribed.
Physical Therapy
Physical therapy plays a crucial role in the rehabilitation of individuals with incomplete spinal cord injuries. Physical therapists design customized exercise programs to improve strength, flexibility, balance, and coordination. These exercises help individuals regain function and enhance their mobility.
Occupational Therapy
Occupational therapists work with patients to regain the skills needed for daily activities such as dressing, grooming, and eating. They teach techniques and provide adaptive tools to enhance independence and quality of life.
Speech Therapy
For individuals with cervical or high thoracic spinal cord injuries, speech therapy may be necessary to address any respiratory or speech difficulties. Techniques and exercises are used to improve breathing, swallowing, and speech production.
Assistive Devices
Assistive devices like wheelchairs, braces, and walking aids can help individuals with incomplete spinal cord injuries regain mobility and independence. These devices are often customized to meet the specific needs of each patient.
Electrical Stimulation
Functional electrical stimulation (FES) involves the use of electrical currents to stimulate muscles and nerves, helping individuals with incomplete spinal cord injuries regain movement and function. FES may be used during physical therapy sessions or as part of a home exercise program.
Psychotherapy And Counseling
Emotional and psychological support is crucial for individuals coping with the challenges of an incomplete spinal cord injury. Psychotherapy and counseling can help patients address depression, anxiety, and the psychological impact of the injury.
Support Groups
Joining support groups and connecting with others who have experienced similar injuries can provide valuable emotional support, encouragement, and practical advice for adapting to life with an incomplete spinal cord injury.
Lifestyle Modification
Rehabilitation often includes education on lifestyle modifications, such as proper nutrition, skin care, and bladder and bowel management, to prevent complications and maintain overall well-being.
Ongoing Care
An incomplete spinal cord injury requires ongoing medical care, regular check-ups, and potential adjustments to the treatment plan as the individual's condition improves.
A multidisciplinary approach involving healthcare professionals from various fields ensures comprehensive care and maximizes the chances of recovery and improved quality of life.
