Brief Summary:
This study will explore physical and physiological responses to mobilization of patients with acquired brain injuries in subacute phase using a classic standing frame and a standing device with simultaneous passive movement of legs, Innowalk Pro.

Condition or disease Intervention/treatment Phase
Brain Injuries Device: Use of standard standing frame Device: Use of a new device;Innowalk Pro Not Applicable

Detailed Description:

Several studies underline the importance of early mobilization of patients with brain injuries, leading to shorter hospital stays, less contractures, and improved general function.

The routine mobilization treatment in the rehabilitation of patients with severe brain injuries in Sunnaas Rehabilitation hospital is initial use of a tilt table where tilt angle is gradually increased, and when tolerated standing in a classic standing frame where the pasient's lower body is fixed to the device in an upright standing position.

Innowalk Pro is a robotic standing device where legs are fixed, but passively moved by electric motors in an upright standing position. An assumption is that standing in Innowalk pro might be better tolerated at an earlier stage of rehabilitation than standing in a classic standing frame.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 25 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Intervention Model Description: All together each included patient will attend five sessions. First session includes an orthostatic test and other baseline measurements. In order to describe test-to-test variation (reliability) when using the devices, two sessions are held in standard standing table (A) and two sessions in Innowalk Pro (B), preferably within the same week. If, for practical reasons, this is not feasible, training is allowed in the following week. The order of the workouts is block randomized to ABAB or BABA at inclusion. The orthostic test and the training session are estimated to last approx. 1 hour including all measurements.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Responses on Use of Standing Frame and Innowalk Pro in Subacute Patients With Severe Functional Deficits Due to Aquired Brain Injury.

Primary Outcome Measures :
  1. Standing time in minutes [ Time Frame: Up to one week ]
    Tolerated maximal standing time in each standing device.

  2. Blood pressure [ Time Frame: up to one week ]
    Blood pressure is monitored continuously

Secondary Outcome Measures :
  1. Heart rate [ Time Frame: up to one week ]
    Heart rate will be monitored continously 5 minutes before and during intervention with Polar 5000

  2. Muscle activity in legs [ Time Frame: up to one week ]
    Any muscle activity in legs during standing session will be monitored by EMG using Musclelab (Ergotest Innovations) on vastus medialis, hamstrings, tibialis ant. and gastrocnemius muscles

  3. Spasticity [ Time Frame: up to one week ]
    Spasticity in knee flexors and ankle flexors will be mearured by Modified Ashworth scale (0-4 where 0= no increase in tone and 4 = rigid limb)

  4. Percieved exertion [ Time Frame: up to one week ]
    For patients who are cognitive capable, percieved exertion willl be registrated on Borg Scale of percived exertion

  5. number of patients reporting pain [ Time Frame: up to one week ]
    Negative impact during training

  6. rate of skin issues [ Time Frame: up to one week ]
    The number of patients reporting

  7. number of near faints will be registered by the staff. [ Time Frame: up to one week ]
    Negative impact during training
