• Conditions: Traumatic Brain Injury With Prolonged Loss of Consciousness
• Interventions: Other: Multisensory Stimulation; Other: Control

• Registration Number: NCT02589223
• Lead Sponsor: Unity Health Toronto

Brief Summary

St. Michael's Hospital (SMH) provides service to individuals with some of the most severe brain injuries and intensive care needs in Canada. These patients often require prolonged intensive care admissions, lengthy hospital stays, involvement of many health professionals, and long-term support for ongoing care requirements. Many hospitals face resource limitations, specifically involving the health disciplines and their ability to provide frequent intervention.

It has been proposed that multisensory stimulation (i.e. exposing the patient to various sights, sounds, smells, etc.) in the early stages of brain injury recovery may result in improved responsiveness/cognitive function.

Previous research has indicated a potential benefit for early multisensory stimulation intervention for patients with severe brain injury. However there is still not enough conclusive evidence to confirm whether the intervention is truly effective. The investigators are proposing a pilot randomized controlled study (placebo-controlled, double-blinded) to determine the feasibility and examine the effectiveness of early multisensory stimulation with patients following severe brain injury who remain in a coma, vegetative state, or minimally conscious state. Eligible patients will be randomized to a control group (standard care + family/caregiver education) or an intervention group (standard care + family/caregiver education + early sensory intervention). Data regarding number of patients enrolled, amount of intervention completed, percentage of outcome data collected, patient's level of responsiveness and cognitive function will be collected before and after the intervention period, using several outcome measures. The investigators hope to determine the feasibility of conducting this type of study within this clinical setting and the effectiveness of multisensory stimulation with this patient population.

Arm && Interventions

Group	Intervention	Description
Multisensory Stimulation Group	Multisensory Stimulation	Intervention sessions will occur 3 times per week, for approximately 30 minutes per session for a total of 4 weeks. Subjects assigned to the multisensory stimulation group will receive the multisensory stimulation protocol designed for the study, which will include a variety of techniques designed to awaken the individual. Stimulus provided may include: visual activities (i.e. presenting the individual with objects/pictures to look at), auditory information (i.e. playing music or speaking), tactile stimuli (i.e. touching the individual with materials of different textures), taste and smell stimuli (i.e. offering items for the individual to taste or smell).
Control Group	Control	Intervention sessions will occur 3 times per week, for approximately 30 minutes per session for a total of 4 weeks. During each session, subjects will be played a pre-recorded reading of complex material for 30 minutes, in order to assist with control/blinding.

Primary Outcome Measures

Name	Time	Method
Western Neurosensory Stimulation Profile - to assess change in alertness and cognitive functioning	To be administered pre intervention (once consent obtained and prior to intervention - to obtain baseline data) and post intervention (after 4 week intervention period to determine change in alertness/cognitive functioning post intervention).

Secondary Outcome Measures

Name	Time	Method
Glasgow Coma Scale	To be administered pre intervention (once consent obtained and prior to intervention - to obtain baseline data) and post intervention (after 4 week intervention period to determine change in alertness/responsiveness post intervention).
Duration of each intervention session (minutes)	To be collected at the end each intervention session throughout the 4 week intervention period.
Pre/post-intervention heart rate (beats/minute)	To be collected at the beginning and end of each intervention session throughout the 4 week intervention period.
Sp02 reading (percentage)	To be collected at the beginning and end of each intervention session throughout the 4 week intervention period.
ICU Mobility Scale Score	Daily scores are recorded and eventually averaged over 4 week intervention period.
Ranchos Los Amigos Levels of Cognitive Functioning Scale	To be administered pre intervention (once consent obtained and prior to intervention - to obtain baseline data) and post intervention (after 4 week intervention period to determine change in alertness/cognitive functioning post intervention).
Enrollment rates	To be collected during the patient enrollment process (study duration approximately 1 year).
Number of intervention sessions (control or multisensory stimulation) per patient over 4 week period	To be collected at the end of 4 week intervention period.
Barriers to enrollment	To be collected during the patient enrollment process (study duration approximately 1 year).
Respiratory Rate (breaths/minute)	To be collected at the beginning and end of each intervention session throughout the 4 week intervention period.
Date of patient transfer from TNICU to ward	To be collected when patient transferred from TNICU to ward (which may be at any time throughout study period, up to 6 months after study enrollment).
Discharge Destination	To be recorded when patient is discharged/transferred from hospital (which will be at any time, up to 6 months after study enrollment).
Barriers to intervention	To be collected (as applicable) at the end of each intervention session throughout the 4 week intervention period.
Patient length of stay (days)	To be collected when patient is discharged/transferred from hospital. (which will be at any time, up to 6 months after study enrollment).
