Fear of falling is associated with numerous negative health outcomes in older adults and can limit rehabilitation. Few treatments are effective in fear of falling. Hypnosis is now recognized as an effective treatment for a variety of conditions, especially anxiety and pain, which can be integrated safely with conventional medicine. Therefore, the objective was to assess the feasibility of a randomized controlled trial to examine whether hypnosis reduces fear of falling in an inpatient geriatric population. In this randomized pilot trial, patients hospitalized in geriatric rehabilitation wards were randomly allocated to either an intervention group (hypnosis plus usual rehabilitation program) or a control group (usual rehabilitation program only). Primary feasibility outcomes were recruitment rate, retention rate, and adherence to the intervention. Secondary outcomes concerned the impact of hypnosis in rehabilitation in fear of falling scores, functional scores, length of stay, and drugs.

This single-center randomized controlled feasibility trial was conducted in a 296 beds acute care and rehabilitation geriatric hospital of Geneva University Hospitals (Switzerland). After consent, patients were randomized to either the intervention group or the control group. The randomization sequence was computer-generated (ratio 1:1) and concealed until official patient enrolment. All study staff members, including physiotherapists and occupational therapists, were blinded to group allocation, with the exception of the hypnotherapist. All statistical analyses were performed by a blinded statistician. The intervention consisted of two hypnosis sessions of about 30 minutes, weekly provided, by a physician trained in medical hypnosis. Each session was realized as possible during walking, according to the agreement and the physical status of the participant. The intervention was provided in the complement of the usual rehabilitation program. Both the intervention and control groups received the usual rehabilitation program, a multifactorial fall-and-fracture risk-based assessment, and management intervention, which has been shown to be effective in improving physical parameters related to the risk of fall and disability among high-risk oldest-old patients. This program includes intensive physiotherapy for 2 weeks (i.e., focused on walking and enhancing balance exercises in group or individual and group) and patient education on the risk of falling and on prevention of falls. The target sample size was 30 participants (15 participants in each group, pilot study). The study was approved by the State of Geneva's Ethics Committee (2018-01550). All patients provided written informed consent before any study-related procedure. The feasibility of a randomized controlled trial with hypnosis in rehabilitation was assessed by recruitment rate, retention rate, adherence to hypnosis, and adverse events. Fear of falling was assessed by different validated scales. Each scale was completed by each participant three times (week 0 (at baseline): before intervention; week 1 (during intervention): between the two hypnosis sessions; week 2 (at the end of the study): after all interventions), with or without the help of the occupational therapist. Descriptive statistics were reported as mean ± standard deviation or number (percent). The hypnosis and the control groups were compared at baseline using t-tests or Fisher's exact test as appropriate. Longitudinal data were analyzed according to the intention-to-treat concept. Longitudinal data for fear of falling scores, Functional Independence Measure score, and Short Physical Performance Battery score, were analyzed using linear mixed-effects regression models, a negative binomial model for in-hospital falls, and t-tests for medications and length of stay. The incidence of in-hospital falls during hospital stay was analyzed using a negative binomial regression model.
