Neuropsychological and Electrophysiological Effects of Dance Therapy With People With Severe Mental Disorders

A single-centre prospective randomised controlled trial will be conducted with a minimum of 47 patients with severe mental disorder (SMD) who will be randomly assigned into two groups, 1 intervention group receiving dance therapy (n=26) and 1 control group who will not receive any intervention or added treatment apart from continuing with their usual treatment (pharmacological), but will not receive intervention with dance therapy (n=21).

In summary, the groups are:

* Experimental group (n=26): people with SMD receiving dance therapy.
* Control group (n=21): people with SMD who do not receive the dance therapy intervention but do receive their usual pharmacological treatment.

Tests will be administered before the start of the study and at the end of the study, as well as 3 months after the end of the study in order to compare the results between groups.

All the tests (BASC, MoCA, PANSS and EEG) will be carried out with the 47 patients with SMD to find out their baseline status. The people with SMD will be randomly assigned to an experimental group (dance therapy program) or a control group (without intervention in dance therapy but with regular pharmacological treatment). The study will last approximately 1 year between the administration of tests, the program and the analysis of results. The dance therapy program will last 20 sessions over 10 weeks. The sessions will take place at the headquarters of the Canarian Association of Creative Therapies (ASCATEC) in the 21st century space in Santa Cruz de Tenerife.

The 26 people with SMD in the experimental group will participate in a 10-week intervention program with 2 sessions per week in which they will work for 1 hour on memory, attention and executive functions through dance and movement, ending with 10 minutes of Mindfulness.

The 21 people in the control group will not receive any type of dance therapy intervention, but will continue with their usual pharmacological treatment.

The effects will be measured after a treatment of 20 sessions (twice a week). Results will be obtained by analysing EEG parameters (EEG amplitude and frequency) and cognitive functions (BACS and MoCA). On the other hand, at the end of the 20-session programme, tests will also be administered to assess the symptomatology of the severe mental disorder suffered by the person (PANSS) to assess the effects of the program on these variables.
