NCT00430703

Brief Summary

The aim of this study is to determine whether passive gait training increases arousal, demonstrated as changes in EEG (electroencephalogram) activity. Hypotheses: 1) Passive gait training increases EEG-frequency in patients with impaired consciousness due to severe traumatic brain injury. 2\) Passive gait training increases conductivity speed of the cognitive P300-component of ERP in patients with impaired consciousness due to severe traumatic brain injury.

Outcome Measures

Primary Outcomes (1)

  • EEG: difference in the frequency spectrum after training.

    0-30 minutes after training end

Secondary Outcomes (5)

  • EEG: absolute power i every frequency band; median frequency;

    0-30 minutes after training end

  • frequency ratios: Alpha versus delta;delta and theta versus alpha and beta;

    0-30 minutes after training end

  • ERP: amplitude of P300-component.

    30-60 minutes after training end

  • ERP: latency of P300-component.

    30-60 minutes after training

  • clinical measure: RLAS (Rancho Los Amigos Scale)

Study Arms (2)

1

EXPERIMENTAL

Patients with severe traumatic brain injury

Behavioral: body weight support treadmill training

2

EXPERIMENTAL

Healthy volunteers

Behavioral: body weight support treadmill training

Interventions

Gait training: Gait robot (Lokomat®, Hocoma, Switzerland) is adjusted to the patient/healthy volunteer individually with chest strap, pelvic straps, harness, leg cuffs and foot lifters. Weight is adjusted individually, so there is a minimum weight support (i.e. when one foot is standing on the treadmill the other foot lifts free from the treadmill thereby simulating normal gait). Gait speed is 1,7-2,3 km/hour (speed can be changed and adjusted that the normal step length is achieved).The duration of the training session is 20 minutes.Blood pressure and pulse are monitored.
