Autonomic Dysreflexia
Autonomic dysreflexia is a potentially life-threatening medical condition that can arise as a secondary health complication after a spinal cord injury (SCI) as the body’s regulation of blood pressure is compromised.
It entails a sudden surge in blood pressure coupled with alterations in heart rate and additional symptoms such as headaches and perspiration. Autonomic dysreflexia triggers a sudden, and potentially dangerous, elevation in blood pressure above an individual’s normal systolic blood pressure. Given that the baseline blood pressure of people living with SCI tends to be lower compared to those without SCI, the rapid elevation in blood pressure may fall within the range typically deemed “normal” or “slightly elevated,” yet it could still be excessively high for the individual.
Autonomic dysreflexia commonly affects individuals with SCI at T6 and higher levels (occasionally extending as low as T8). Generally, those with higher-level injuries and complete impairments are at heightened risk of experiencing autonomic dysreflexia. This condition can manifest at any point following the occurrence of the SCI. This spike in blood pressure is often accompanied by various symptoms, which can vary widely in severity from mild discomfort to severe, life-threatening conditions.
Autonomic dysreflexia can be triggered by various types of stimuli below the level of SCI. This includes anything that would typically be considered uncomfortable, irritating, or painful if it could be felt, such as wounds. Additionally, normal bodily functions that exert strong stimulation, like having a full bladder or sexual arousal, can also prompt autonomic dysreflexia.
Autonomic dysreflexia occurs due to dysfunction of the autonomic nervous system due to SCI, resulting in poorly controlled blood pressure responses.
The autonomic nervous system oversees unconscious bodily processes like blood pressure, heart rate, and digestion. It comprises two divisions:
- The sympathetic nervous system, known as the ‘fight or flight’ system, readies the body for action by increasing heart rate and constricting blood vessels.
- The parasympathetic nervous system, dubbed the ‘rest and digest’ system, allows the body to recuperate by slowing heart rate and relaxing blood vessels.
These systems have distinct effects on organs and work in tandem to regulate bodily functions.
Blood pressure is meticulously regulated to ensure proper circulation. The body monitors blood pressure and adjusts it by constricting or dilating blood vessels and altering heart rate.
During autonomic dysreflexia, strong stimulation below the level of the SCI activates the sympathetic nervous system, causing blood vessels in the lower body to constrict, leading to a rise in blood pressure. Normally, the brain would signal to relax blood vessels and slow heart rate, restoring blood pressure to normal. However, in SCI, the signal to relax blood vessels is blocked from reaching the lower body, resulting in sustained constriction of blood vessels and uncontrolled elevation of blood pressure.
Autonomic dysreflexia is a medical emergency and requires immediate treatment. Initial steps involve sitting upright, loosening tight clothing, and addressing the trigger, such as emptying a full bladder or bowel. If blood pressure remains high, emergency medical attention is necessary. Emergency treatments may include medications to rapidly lower blood pressure.
Preventing autonomic dysreflexia involves identifying triggers and taking preventive measures. Strategies include maintaining bladder and bowel routines, managing reflex spasms, preventing irritation during procedures, and considering surgical interventions for chronic issues.
Pressure Injuries
Pressure injuries, also referred to as pressure wounds, ulcers or bed sores, occur when pressure, friction or shear leads to skin and tissue breakdown. Individuals with spinal cord injuries (SCI) are particularly vulnerable due to changes in how their body functions and the increased likelihood of prolonged pressure on specific areas like the sit bones, heels, elbows and tailbone. These injuries can lead to various complications, including difficulty in healing, infections (potentially leading to sepsis), prolonged hospital stays, reduced independence and mobility, decreased life satisfaction and increased reliance on caregivers.
Pressure injuries result from a combination of internal and external factors. Internal factors include changes in skin elasticity, loss of sensation and movement and reduced ability to fight infections. External factors include prolonged pressure on specific areas, friction, shear forces, moisture, body weight changes and unsupportive surfaces.
Pressure injuries are classified into stages based on their severity, ranging from Stage 1 (minor redness) to Stage 4 (deep tissue injury exposing bone, tendon, or muscle) with the more severe injuries classified as unstageable wounds and deep tissue injuries. Early identification of the stage is crucial for determining treatment.
Diagnosis involves regular skin checks, physical examinations and, if necessary, additional tests like blood tests or ultrasound imaging to assess tissue damage and potential infections. Early identification of pressure injuries allows for prompt intervention and treatment.
Prevention is paramount and involves various strategies. These include maintaining good skin care through regular skin checks, using appropriate equipment and seating to reduce pressure, implementing pressure relief techniques, adopting a healthy lifestyle and seeking peer support. Regular exercise, proper nutrition and avoiding smoking are crucial components of prevention.
Treatment options depend on the severity of the injury. They may include wound care, dressings, medications (such as antibiotics), energy-based therapies (like electrical stimulation and ultraviolet C light), debridement (removal of dead tissue), flap reconstruction surgery, amputation (in severe cases), negative pressure wound treatments and other medical or physical interventions tailored to the individual’s needs.
Preventing pressure injuries is paramount for individuals with SCI. Through a combination of preventive measures and timely treatment, the risk of complications can be minimized, allowing individuals to maintain their quality of life and independence. Regular communication with healthcare providers is essential to identify and address potential pressure injury risks effectively.
Respiratory Dysfunction
Spinal cord injury (SCI) can profoundly affect breathing and coughing functions, presenting challenges that require acute management strategies.
- SCI disrupts the intricate network of nerves responsible for coordinating respiratory muscles, leading to impaired breathing function.
- Muscle paralysis or weakness resulting from SCI hampers the ability to engage in deep breathing and effective coughing, crucial for clearing airways.
- Reduced lung compliance complicates the process of expanding the lungs fully, impacting oxygen intake and carbon dioxide elimination.
- Compromised coughing ability increases susceptibility to respiratory infections such as pneumonia, posing further challenges to respiratory health.
- Swallowing difficulties post-SCI heighten the risk of aspiration, where food or liquid enters the lungs instead of the stomach, exacerbating respiratory complications.
- Secretion removal techniques, including postural drainage and assisted coughing, play a pivotal role in clearing mucus from the airways, preventing congestion and infections.
- Respiratory muscle training regimens aim to enhance the strength and endurance of breathing muscles, facilitating more efficient ventilation.
- Bronchodilators, though cautiously used due to potential side effects, can help alleviate airway constriction and improve breathing function.
- Mechanical ventilation serves as a critical intervention in severe cases, providing essential respiratory support either invasively through intubation or non-invasively through masks or nasal prongs.
- Atelectasis, characterized by partial or complete lung collapse, is a common complication post-SCI, impairing oxygen exchange and necessitating prompt intervention.
- Pneumonia, often exacerbated by compromised coughing ability and weakened immune function, poses a significant threat to respiratory health.
- Pulmonary embolism, resulting from blood clots traveling to the lungs, presents a risk, particularly in the early stages post-injury, necessitating vigilant monitoring and preventive measures.
- Pulmonary edema, marked by fluid accumulation in the lungs, and respiratory failure, where oxygen levels plummet and carbon dioxide accumulates, underscore the complexity of respiratory complications post-SCI.
- Lifestyle modifications, including smoking cessation and adequate hydration, are vital for maintaining respiratory health and minimizing infection risk.
- Vaccination against influenza and pneumonia is imperative to bolster immune defenses and prevent respiratory infections.
- Regular exercise regimens tailored to individuals with SCI strengthen respiratory muscles and promote overall lung function.
- Incorporation of secretion removal techniques and specialized equipment in daily respiratory care routines enhances long-term respiratory health.
- Emerging research exploring electrical stimulation techniques offers promising avenues for assisting breathing post-SCI, underscoring the importance of ongoing advancements in respiratory management strategies.
Respiratory dysfunction following SCI encompasses a spectrum of challenges that require a multifaceted and tailored approach to management. By comprehensively understanding the intricacies of respiratory complications post-SCI and implementing effective interventions, individuals can optimize respiratory function, mitigate risks, and enhance overall well-being.
Bowel & Bladder
Spinal cord injury (SCI) can significantly impact bowel and bladder function, leading to various challenges in daily life. Understanding these changes is crucial for effective management and improving quality of life. This comprehensive guide explores the types, symptoms, diagnosis, management, and complications of bowel and bladder dysfunction after SCI.
Bowel Dysfunction After SCI:
The gastrointestinal (GI) tract plays a vital role in extracting nutrients from food and eliminating waste from the body. However, after SCI, nerve signals between the brain and the bowel may be disrupted, resulting in neurogenic bowel dysfunction. This can lead to:
- Reduced sensation
- Slow movement of stool
- Loss of bowel control
Types of Bowel Dysfunction:
- Spastic Bowel: Occurring with injuries at or above the T12 level, this involves retained bowel reflexes, but a loss of control from the brain. Symptoms include constipation and difficulty passing stool.
- Flaccid Bowel: Typically occurring with injuries below the T12 level, this involves a loss of bowel reflex activity and muscle tone, leading to involuntary leaking of stool.
Bladder Dysfunction After SCI:
Neurogenic bladder, another consequence of SCI, manifests in various ways:
- Spastic Bladder: This overactive bladder type occurs with injuries above the T12 level, causing symptoms such as incontinence, frequent urination and reduced bladder sensation.
- Flaccid Bladder: Occurring with injuries below the T12 level, this underactive bladder type results in urinary retention, incomplete emptying and bladder wall damage.
Diagnosis:
Comprehensive evaluation is crucial for diagnosing bowel and bladder changes after SCI. This includes:
- Medical history
- Symptoms assessment
- Physical examination
- Tests like urodynamic testing, imaging, and cystoscopy.
Management Strategies:
Effective management of bowel and bladder dysfunction after SCI involves:
- Bowel Management: Implementing a regular bowel routine including diet, lifestyle changes and techniques like digital stimulation. Surgical options like colostomy may be considered in severe cases.
- Bladder Management: Developing personalized bladder care routines utilizing catheters, medications, surgical procedures and other interventions to manage symptoms and prevent complications.
Complications:
Complications related to bowel and bladder changes after SCI include:
- Urinary tract infections
- Kidney and bladder stones
- Kidney damage
- Bladder cancer

Regular monitoring and proactive management are essential for individuals with SCI to prevent complications and maintain overall health and quality of life. If you have concerns about bowel or bladder changes after SCI, consult with a healthcare professional for personalized guidance and support.
Sexual Function
Sexual health often changes after a spinal cord injury (SCI), affecting many aspects of an individual’s life.
It includes physical, emotional, mental and social well-being as a sexual being, enabling participation in healthy, meaningful sexual activities tailored to personal needs and values. Post-SCI, individuals may experience altered sexual desire, sensation, arousal and orgasm due to the injury. Other injury-related changes, such as those affecting bladder and bowel control, movement, self-image and life roles, can also impact sexual health. Various treatments and techniques, including medications, physical treatments and adaptive devices, can help improve sexual arousal and satisfaction.
Understanding the functioning of sex organs helps in comprehending changes post-SCI. For men, erections involve increased circulation to the penis; for women, arousal involves vaginal lubrication and increased circulation to the vagina and clitoris. SCI can disrupt nerve signals between the brain and sex organs, affecting sexual responses in various ways. Common issues include reduced or altered sensations, erectile dysfunction in men, and difficulties with arousal and orgasm in women. Both genders may experience changes in sexual desire due to physical and emotional factors.
Self-image and confidence can be impacted after SCI, affecting sexual attractiveness and comfort. Relationships may also be affected, with changes in roles and caregiving responsibilities influencing sexual health. Fertility issues are more common in men, often requiring medical interventions for sperm retrieval, while women’s fertility is usually unaffected, though menstruation might be temporarily disrupted.
Bowel and bladder control loss can lead to accidents during sex, causing anxiety and self-consciousness. Maintaining a regular care routine, emptying the bladder and bowel before sexual activity, and using waterproof sheets can help manage these issues. Communication with partners about these concerns is beneficial. Positioning and movement during sex might become challenging due to changes in movement control and flexibility, making assistive devices and different positions useful.
There are various medical treatments and techniques available to help improve sexual arousal and satisfaction after SCI. For men, treatments for erectile dysfunction include medications like Viagra, Levitra, Cialis, injectable medications, vacuum devices, surgical implants, pelvic floor exercises and vibration techniques. Women can benefit from clitoral stimulation, vacuum devices and experimental treatments aimed at enhancing sexual arousal and response.
Autonomic dysreflexia, a serious condition characterized by a sudden rise in blood pressure, can occur during sexual activity in individuals with injuries at T6 and above and requires immediate attention. Some medications for SCI symptoms, such as Baclofen for spasticity, may have sexual side effects, necessitating discussions with healthcare providers. Skin care during sexual activity is crucial to avoid pressure injuries.
A sexual health assessment for individuals with SCI, conducted by specialized healthcare providers, includes reviewing general and sexual health history, focusing on the SCI, functional abilities, other health conditions, medications, and current treatments. The assessment may also involve a physical exam to test movement control, muscle tone, sensation in the pelvic region and genital reflexes.
Neuropathic Pain
Neuropathic pain, stemming from nerve damage, is a prevalent and severe issue for individuals with SCI.
Unlike other types of pain, neuropathic pain may manifest as burning, tingling, shooting or electric shock sensations, often occurring spontaneously or in response to non-painful stimuli.
Types of Neuropathic Pain:
- At-Level SCI Pain: Felt at or near the level of injury, typically as a band of pain around the torso, neck or along the arms or legs.
- Below-Level SCI Pain: Experienced in areas below the level of injury, including regions lacking other sensation.
- Other Neuropathic Pain: Arising from nerve injuries unrelated to the SCI, such as carpal tunnel syndrome.
Chronic neuropathic pain persists for extended periods, altering the nervous system’s perception of pain and making it challenging to manage effectively. This type of pain often requires specialized treatment approaches.
Several medications, including anticonvulsants, antidepressants, anesthetics and cannabinoids, offer relief from neuropathic pain by targeting specific pain pathways in the nervous system. Psychological therapies like cognitive-behavioral therapy and biofeedback can also help individuals manage neuropathic pain by addressing psychological contributors.
Physical therapies such as acupuncture, and transcutaneous electrical stimulation provide additional options for neuropathic pain management. These treatments aim to modulate pain signals in the nervous system and improve overall pain perception.
In severe cases, surgical procedures like dorsal rhizotomy or myelotomy may be considered to interrupt pain signals transmitted by damaged nerves. However, surgery is typically reserved for cases where other treatments have proven to be ineffective.
Neuropathic pain presents unique challenges for individuals with SCI, requiring specialized approaches for effective management. By combining medication, psychological therapies, physical treatments and surgical interventions as needed, individuals can alleviate neuropathic pain and improve their quality of life post-injury.
Spasticity
Spasticity is a common secondary health complication experienced by individuals with spinal cord injury (SCI), affecting movement control due to damage or improper development of the brain and spinal cord.
It’s characterized by involuntary muscle spasms, increased muscle tone and overactive reflexes. Spasticity can significantly impact daily life, causing movement difficulties, pain, fatigue and more.
The triggers for spasticity vary widely, ranging from movement and position changes to emotional stress and health issues like bladder or bowel problems. Effective management involves identifying and addressing these triggers, along with utilizing conservative treatments such as positioning, stretching and avoiding aggravating factors.
Treatment approaches for spasticity encompass a range of modalities. Oral medications like baclofen and tizanidine are commonly prescribed to manage widespread spasticity, while botulinum toxin injections (Botox) can target localized areas. Physical therapy techniques, including stretching, range of motion exercises and functional electrical stimulation, aim to reduce spasticity and prevent complications like contractures. In severe cases where other treatments fail, surgical interventions such as tendon releases or myelotomy may be considered.
While spasticity presents challenges, it also provides some advantages for individuals living with SCI. It enhances mobility by providing support for standing, walking and transferring, while also preventing muscle wasting due to inactivity. Moreover, the involuntary muscle contractions improve circulation, reducing the risk of blood clots and promoting overall blood flow. Spasticity can also assist in certain aspects of daily living. Intentionally triggered spasms can facilitate bowel and bladder emptying and reflex erections during sexual activity can occur enhancing sexual function for some individuals. Changes in spasticity levels can serve as warning signs for potential infections or other health issues.
Managing spasticity after SCI requires a comprehensive approach involving various treatments tailored to individual needs. Collaborating with healthcare providers to assess symptoms, identify triggers and explore treatment options can help individuals effectively manage spasticity and improve their quality of life.
With no known cure, a spinal cord injury (SCI) is a lifelong medical condition. An SCI is more than just sensory and mobility paralysis, it also affects every physiological system in the body. On average, a person with an SCI experiences 15 secondary health complications at any given time, which range from mild daily occurrences to severe life-threatening conditions, which are the leading causes of death for individuals with a spinal cord injury.
Many of the secondary complications of SCI are shared with other chronic health conditions. Despite being costly to manage and an ongoing concern to millions of Canadians, most secondary complications of SCI have out-dated and, in many cases, ineffective solutions that greatly limit the quality of life for many Canadians.
