Plain English Summary
Background and study aims
The spinal cord is a soft bundle of nerves that extends from the base of the brain to the lower back, through which the brain sends movement commands and receives sensory information. Spinal cord injury (SCI) is a catastrophic event associated with disruptions to the movement, sensory, cardiovascular (heart), and respiratory (breathing) systems. The aim of this study is to assess the effects of SCI on breathing function and the muscle power of the limbs, and whether treatment reverses these changes during the 6-month follow-up period.
Who can participate?
Acute Spinal Cord Injury (SCI) patients aged 20-70
What does the study involve?
Patients participate in a 12-week exercise rehabilitation program at least three times per week for 20 to 30 minutes, and a 12-week respiratory (breathing) muscle training program. At the start of the study and after 2 weeks, 1 month, 3 months and 6 months, participants undergo measurements including: breathing function, muscle power, heart rate, blood pressure, blood tests and brain MRI scans.
What are the possible benefits and risks of participating?
The blood test may cause short-term discomfort, bleeding or swelling. The other tests are not invasive and do not involve any risks for the patient.
Where is the study run from?
Chang Gung Memorial Hospital - Kaohsiung Branch (Taiwan)
When is the study starting and how long is it expected to run for?

Study information
Scientific title
Early aggressive respiratory therapy and rehabilitation interventions in the role of the prognosis of patients with acute traumatic spinal cord injury and explore oxidative stress, inflammation, DNA damage, leukocyte apoptosis and endothelial dysfunction, and its association with cardiovagal function and cerebral autoregulation
Acronym
Study hypothesis
Hypothesis: Endothelial oxidative stress and inflammation are increased, endothelium repair capacity are reduced, leukocyte apoptosis are decreased, and decreased gain of baroreflex sensitivity and cerebral autoregulation in patients with acute SCI compared with healthy subjects, and treatment reverses these biomarkers alterations, and changes of baroreflex sensitivity and cerebral autoregulation during the 6-month follow-up period.
The study will also explore which signaling pathways involved in the apoptosis of EPCs. The successful translation of these approaches to the clinics offers the promise of not only predicting the outcome but also assessing the impact of these factors on therapeutic efficacy.

Condition
Acute spinal cord injury
Intervention
Rehabilitation treatment: Patients participated in a 12-week exercise program. They performed mobility, strength, range of motion, aerobic resistance, and ambulation training. A minimum exercise frequency of 3 times per week and a minimum duration of 20 to 30 minutes, and an exercise intensity of 70% to 80% of heart rate reserve is necessary to produce training effects.
Respiration treatment: Patients participated in a 12-week respiratory muscle training (RMT) program, including maximal expiratory pressure (MEP) and maximal inspiratory pressure (MIP) monitor.

Primary outcome measure
Measured at baseline, 2 weeks, 1 month, 3 months and 6 months:
1. Mechanical ventilation free rate (no mechanical ventilator used) at discharge
2. Respiratory function:
2.1. Maximal inspiratory pressure (MIP) measured with a pressure manometer
2.2. Maximal expiratory pressure (MEP) measured with a pressure manometer
2.3. Rapid shallow breathing index (RSBI, respiratory rate/tidal volume) measured using Haloscale
3. Muscle power of limbs, measured using Japanese Orthopaedic Association (JOA) cervical spine myelopathy functional assessment score
Secondary outcome measures
Measured at baseline, 2 weeks, 1 month, 3 months and 6 months:
1. Endothelial oxidative stress, measured using ELISA
2. DNA damage, measured using RT-PCR
