Study summary

The purpose of the current study is to investigate the effects of powered exoskeleton (EKSO) on cardiovascular performance as measured by resting blood pressure and heart rate, peak oxygen consumption during walking, energy expenditure, whole and regional body composition assessments. The effects of exoskeleton training on walking kinematics including stand-up time, walking time, distance covered and speed of walking will also be evaluated.

Read the detailed description

Powered exoskeletons using robotic suits have recently been introduced for the rehabilitation of persons with spinal cord injury (SCI). Exoskeletons offer a unique opportunity for persons with SCI to experience standing and walking at a low metabolic cost. Evidence suggested that exoskeleton assisted walking can decrease spasticity and improve bowel movement. Training may also improve the level of physical activity as well as psychological parameters that are likely to interfere with rehabilitation outcomes. Previous studies reported that a frequency of 2-3 times per week or more for 1-2 hours may be beneficial in the rehabilitation of persons with SCI. Using exoskeletal-assisted walking to improve the level of physical activity may be appealing to persons with SCI.

Exoskeleton training for 12 weeks may enhance energy expenditure, parameters of physical activity and result only on modest effects on both cardiovascular and body composition parameters. In other words, persons with tetraplegia may have greater cardiovascular and body composition adaptations compared to persons with paraplegia. Twenty subjects will participate in a powered exoskeleton (EKSO) for one or twice a week for 12 weeks. The program will involve walking with the robotic suits for 1 hour for persons with complete (n=10) and persons with incomplete (n=10) SCI.

What researchers measure

Primary outcomes

  1. Blood Pressure (mmHg)

    Resting blood pressure and post-exercise blood pressure will be measured every visit.

    Time frame: 12 weeks

  2. Walking time (minutes)

    The robotic unit will measure standing up time, walking time and walking distance for every visit.

    Time frame: 12 weeks

  3. Oxygen uptake (l/min)

    Oxygen uptake will be measured during sitting, standing and walking at the beginning and at the end of the training program.

    Time frame: 12 weeks

  4. Body Composition (kg)

    Body composition using dual energy x-ray absorptiometry anthropometrics' will be measured during sitting, standing and walking at the beginning and at the end of the training program.

    Time frame: 12 weeks

Secondary outcomes

  1. Six minute-walk Test (meter)

    The test will competed at the beginning and at the end of study to measure distance.

    Time frame: 12 weeks

  2. Walking Index for Spinal Cord Injury II (WISCI II)

    The test will competed at the beginning and at the end of study

    Time frame: 12 weeks

  3. Electromyography (EMG) activity of 6 muscle groups (mV)

    The test will competed at the beginning and at the end of study

    Time frame: 12 weeks

  4. Mitochondrial health using near infra-red spectroscopy (seconds)

    The test will competed at the beginning and at the end of study

    Time frame: 12 weeks

  5. 10 meter walk Test (m/sec)

    The test will competed at the beginning and at the end of study to measure speed.

    Time frame: 12 weeks
