Persistent vegetative state is regarded as "permanent", if it persists
for more than 1 year for traumatic aetiology, or for more than 3 months for other
aetiologies. This is also the case for patients in a minimally conscious state.
In order to investigate possible improvements after this period we treated and
observed 7 such patients over a period of 6 months. DESIGN AND METHODS: An
ABA-BAB study design was used, with sensory stimulation and social-tactile
intervention as treatment regimes. Changes were documented by clinical evaluation
and blind behavioural assessment through video monitoring. RESULTS: Clinical
scores improved significantly after treatment. Video assessment also indicated
significant changes in the patients' behaviour. During the initial period of
therapy, social tactile interaction improved patients' activity, while sensory
stimulation impaired activity. During the main part of therapy, both types of
treatment yielded similar positive results. CONCLUSION: This study indicates the
possibility of achieving behavioural improvements with regard to the
responsiveness of patients with long-lasting persistent vegetative state and
minimally conscious state by use of long-term treatment.
