Coma stimulation programs were developed on the premise that 
structured stimulation could prevent sensory deprivation and 
accelerate recovery.Sensory input 
may be provided through the vestibular, visual, tactile, auditory, 
and olfactory systems .Emphasis 
should be placed on selecting items that reflect the child's age 
and development, culture, personality, likes/dislikes, hobbies, 
significant relationships, and pets.However, controversy exists regarding the 
efficacy of stimulation used in the care of a comatose child.126 The 
first step is to select appropriate sensory stimuli.In addition, items that are 
selected should be reevaluated periodically, so that ineffective 
stimuli can be eliminatedThe rehabilitation team 
should involve the family in the selection of meaningful items to 
be used for stimulation to individualize the program.
