Efficacy and safety of rehabilitation exercise in neuromyelitis optica spectrum disorder during the acute phase: a prospective cohort study

High-Intensity Gait Training in an Individual With Neuromyelitis Optica and Research Recommendations for Individuals With Multiple Sclerosis

BACKGROUND

Neuromyelitis optica (NMO), similar to multiple sclerosis (MS), is an autoimmune disorder affecting the central nervous system. In people with central nervous system diagnoses, high-intensity gait training (HIGT) can support neuroplasticity, improving functional mobility. While low- to moderate-intensity exercise is beneficial in improving outcomes in individuals with NMO and MS, the impact of HIGT has not been thoroughly explored. This case study explores the safety and efficacy of HIGT in an individual with NMO.

METHODS

A 43-year-old man with NMO participated in a HIGT program utilizing the least amount of body weight support necessary to achieve a target heart rate of 60% to 80% of heart rate reserve or a Borg Rating of Perceived Exertion score of 15 to 17 during an in-patient rehabilitation stay. Interventions incorporated stair training, gait variances, and virtual reality.

RESULTS

The patient successfully completed a 90-minute training session 4 to 7 times per week for 6 weeks following a HIGT regimen for 40% to 60% of each session. Meaningful gains in bed mobility, transfers, and gait allowed for discharge to his home.

CONCLUSIONS

This case suggests that HIGT in patients with NMO can be safe and effective in improving functional mobility. Due to the similarities between NMO and MS, this case provides a framework to assist clinicians in developing a HIGT plan of care for individuals with MS. Additional research is needed to clarify HIGT parameters, including intensity and duration, to improve functional mobility in individuals with MS.

The nutritional risk in patients with neuromyelitis optica spectrum disorder

BACKGROUND

The effect of nutrition on chronic autoimmune diseases is well known. This study is the first to assess the nutritional status of patients with neuromyelitis optica spectrum disorder (NMOSD) by administering the Mini Nutritional Assessment (MNA), to explore the impacts of nutrition on patients' quality of life and to identify the factors associated with the nutritional status of NMOSD patients.

METHODS

Our study enrolled 70 NMOSD patients and 66 healthy controls. The following data were assessed: demographic information, disease features, and composite evaluations of life status, including nutrition, sleep, anxiety/depression, fatigue, and quality of life. Then, statistical analysis was performed.

RESULTS

The MNA score of NMOSD patients was 20.4 ± 3.3, which was significantly lower than that of HCs (23.3 ± 2.5, P = 0.002), especially for the dimensions of global evaluation and anthropometric assessment. Nearly 85% of patients were at risk of malnutrition or had definite malnutrition. The total MNA score was positively correlated with the patient's quality of life (P<0.01). Lower MNA scores were correlated with gender (P = 0.02), longer disease duration (P<0.001), more severe anxiety (P = 0.004), more severe depression (P = 0.003), more severe sleep disturbances (P<0.001), and more severe fatigue (P = 0.01). Sleep disturbance was revealed to be a significant independent factor for the NMOSD patients' malnutritional risk (P = 0.001).

CONCLUSIONS

These results suggest that the risk of malnutrition is very high in NMOSD patients and that malnutrition is closely related to their quality of life. Malnutrition among NMOSD patients is caused by a combination of various physiological and psychological factors. A multifaceted and personalized intervention is required to improve the prognosis of NMOSD.

Impact of dysautonomic symptom burden on the quality of life in Neuromyelitis optica spectrum disorder patients

BACKGROUND

This study aimed to investigate the clinical risk factors of dysautonomic symptom burden in neuromyelitis optica spectrum disorder (NMOSD) and its impact on patients' quality of life.

METHODS

A total of 63 NMOSD patients and healthy controls were enrolled. All participants completed the Composite Autonomic Symptom Score 31 (COMPASS-31) to screen for symptoms of autonomic dysfunction. A comprehensive clinical evaluation was performed on NMOSD patients, such as disease characteristics and composite evaluations of life status, including quality of life, anxiety/depression, sleep, and fatigue. Correlated factors of dysautonomic symptoms and quality of life were analyzed.

RESULTS

The score of COMPASS-31 in the NMOSD group was 17.2 ± 10.3, significantly higher than that in healthy controls (P = 0.002). In NMOSD patients, the higher COMPASS-31 score was correlated with more attacks (r = 0.49, P < 0.001), longer disease duration (r = 0.52, P < 0.001), severer disability (r = 0.50, P < 0.001), more thoracic cord lesions (r = 0.29, P = 0.02), more total spinal cord lesions (r = 0.35, P = 0.005), severer anxiety (r = 0.55, P < 0.001), severer depression (r = 0.48, P < 0.001), severer sleep disturbances (r = 0.59, P < 0.001), and severer fatigue (r = 0.56, P < 0.001). The disability, total spinal cord lesions, and fatigue were revealed to be independently associated factors. Further analysis revealed that the COMPASS-31 score was independently correlated with scores of all the domains of patients' quality of life scale (P < 0.05).

CONCLUSIONS

Dysautonomic symptom burden is correlated with decreased quality of life and certain clinical characteristics such as disability, the burden of spinal cord lesions, and fatigue in NMOSD patients. Investigation and proper management of autonomic dysfunction may help to improve the quality of life in patients with NMOSD.
