Evaluation of the Efficiency of Touch Massage on the Quality of Life at Work of Nursing Staff Working in a Cancer Center. (Pause "Toucher Massage (TM)")

• Touch Massage (Other): The practitioner performs the touch-massage for 15 minutes on clothed personnel in a seated position on an ergonomic massage chair. The massage focuses on the back, neck and arm areas. It's a precise, technical sequence of pressure, stretching and sweeping movements that follows the following pattern: * Basic anti-stress maneuvers to relieve tension, * Relaxation of the upper torso with weightless movements to loosen shoulders and arms, * Stretching, * Redynamization through rapid friction on the back. Burnout, anxiety, affect, and musculoskeletal disorders (MSDs) will be assessed in participants using the following questionnaires at different times of the study.

Primary outcomes

• Burn out [At enrolment and at the end of the 6th session of touch massage (1 session per week for 6 weeks)]: Burnout is assessed using the Maslach Burnout Inventory (MBI) questionnaire, which consists of 3 scales (emotional exhaustion, depersonalisation and personal accomplishment). This score is obtained by adding items 1, 2, 3, 6, 8, 13, 14, 16 and 20, each of which is rated on a 7-point Likert scale (from 0=never to 6=every day). * Total < 17: low burnout * Total between 18 and 29: moderate burnout * Total > 30: high burnout

Secondary outcomes

• Anxiety [At enrolment, at the end of the 6th session of touch massage (1 session per week for 6 weeks) and 6 months after randomisation]: Anxiety will be assessed using the State Trait Anxiety Inventory (STAI TRAIT) questionnaire. The questionnaire consists of 20 items that participants answer on a 4-point scale. Scores range from 20 to 80, with higher scores indicating greater anxiety.
• Affect [At enrolment, at the end of the 6th session of touch massage (1 session per week for 6 weeks), at 3 and 6 months after randomisation]: Affect will be assessed using the Positive And Negative Affectivity Scale (PANAS). The questionnaire consists of 10 items assessing positive and negative affectivity. For each item, the participant responds on an ordered scale of 1 to 5, making it possible to calculate a score ranging from 10 to 50 for each dimension.
• Musculoskeletal disorders [At enrolment, at the end of the 6th session of touch massage (1 session per week for 6 weeks), at 3 and 6 months after randomisation]: Musculoskeletal disorders will be assessed using the Nordic Musculoskeletal Questionnaire (NMQ). This questionnaire is used to record problems such as pain, discomfort and numbness in different parts of the body over the past 12 months and also over the past 7 days. It can also be used to assess the intensity of the problem at the time the questionnaire is completed.
