Long-term studies about orthostatic training after high spinal cord injury

Area of Science:

• Neurology
• Cardiovascular Physiology
• Rehabilitation Medicine

Background:

• Patients with paraplegia, particularly those with upper lesions, often experience significant challenges with circulatory regulation.
• Prolonged bed rest in these individuals can exacerbate autonomic dysfunction, impacting cardiovascular stability.

Purpose of the Study:

• To investigate the long-term circulatory behavior of paraplegics with upper lesions during orthostatic tilt-table testing.
• To assess the effectiveness of therapeutic repositioning in achieving circulatory stabilization in this patient group.

Main Methods:

• Long-term observation of paraplegic patients with upper lesions.
• Inclusion of patients who were completely bedridden for several months prior to the study.
• Utilizing orthostatic tilt-table exercise for circulatory assessment over a minimum of 7 weeks.

Main Results:

• Decisive circulatory stabilization was not achieved in most paraplegic patients with upper lesions.
• There was generally no significant improvement in adaptation to varying orthostatic intensity.
• Marked fluctuations in orthostatic adaptation were observed, with peak circulatory lability sometimes occurring weeks after repositioning to sitting.

Conclusions:

• Paraplegics with upper lesions exhibit persistent circulatory lability and poor orthostatic adaptation.
• Extended periods of orthostatic observation are crucial for accurately assessing the circulatory system's response in these patients.
• Current therapeutic repositioning strategies may not be sufficient for achieving stable circulatory function in this population.
