Brief Summary

Diabetic foot ulcers (DFU) are one of the most serious complications of diabetes and can lead to amputations in 85% of cases, resulting in physical, psychological, family, social and economic consequences. Psychological interventions can contribute to the improvement of wound healing and, relaxation, in particular, seems to contribute to faster wound healing. More research is needed to assess the effectiveness of different types of intervention on different types of wounds, in particular on chronic wounds such as DFU. This is a Pilot Randomised Controlled Study of a Psychological Intervention that aims to evaluate the feasibility and acceptability of a muscle relaxation intervention with guided imagery (experimental group - EG) compared to a neutral guided imagery placebo (active control group - ACG) and a group that does not receive any psychological intervention (passive control group - PCG), to inform a future definitive Randomised Controlled Study (RCT) that tests its effectiveness. This study will also examine, qualitatively, the perspectives of patients with DFU on the relaxation intervention, in order to check its acceptability and applicability; as well as the perspectives of health professionals on this adjuvant therapy, its applicability and integration into the care system of multidisciplinary diabetic foot consultations. Participants have a diagnosis of Diabetes Mellitus and Diabetic Foot; one or two chronic ulcers active at the time of assessment; and clinical levels of stress or anxiety or depression. Participants will be randomized by the three conditions - EG, ACG and PCG - and assessed on the day of the first consultation or nursing treatment for chronic DFU (T0), two months later (T1), and six months later (T2; follow-up). Two weeks after T1, an interview will be conducted with patients with DFU that benefited from the relaxation sessions and to the health professionals who provided them the DFU care. The results of the present study will contribute for a better understanding of DFU progression, healing, prevention of re-ulceration and future amputations and, consequently, for the improvement of patients' quality of life.

Outcome Measures

Primary Outcomes (7)

  • Rate of eligibility

    This rate will result from the proportion between the number of eligible patients and the total number of observed patients, in percentage.

    Baseline (T0)

  • Rate of recruitment

    This rate will result from the proportion between the number of patients who accepted to participate and the number of eligible patients, in percentage.

    Baseline (T0)

  • Rate of refusal

    This rate will result from the proportion between the number of patients who rejected to participate in the study and the number of patients invited to participate, in percentage.

    Baseline (T0)

  • Rate of adherence to the study protocol

    This rate will result from the proportion between the number of patients who performed the assessments/intervention sessions and the number of patients who completed the baseline assessment (T0), in percentage.

    Through study completion, an average of 6 months

  • Rate of participation in follow-up

    This rate will result from the proportion between the number of patients who participated in follow-up assessment and the number of patients who completed the baseline assessment (T0), presented in percentage.

    Through study completion, an average of 6 months

  • Rate of dropout

    This rate will result from the proportion between the number of patients who dropout the study and the number of patients who completed the baseline assessment (T0), presented in percentage.

    Through study completion, an average of 6 months

  • Patient satisfaction with the relaxation intervention

    The degree of patients´ satisfaction with the relaxation intervention will be assessed through questions developed for this purpose, including the degree of general satisfaction with the sessions; the impact on stress, anxiety and depression, and wound healing after the four sessions; the degree of usefulness for patients with DFU; the desire to participate in future sessions; and the recommendation of the sessions to other patients with DFU. All the questions will be assessed on a Likert scale from 1 (very unsatisfied/ none/ totally disagree) to 5 (very satisfied/ extreme/ totally agree).

Study Arms (3)

Muscle Relaxation with Guided Imagery

EXPERIMENTAL

The participants in Experimental Group will receive four individual 45-minute sessions, every two weeks, of progressive muscle relaxation intervention with guided imagery focused on ulcer healing, carried out by the Psychologist responsible for implementing the project, on the day of the Diabetic Foot appointments.

Behavioral: Muscle Relaxation with Guided Imagery

Active Control Group

PLACEBO COMPARATOR

Participants in the Active Control Group will receive four individual 45-minute sessions of neutral guided imagery placebo, carried out by the Psychologist responsible for implementing the project, on the day of the Diabetic Foot appointments.

Behavioral: Neutral Guided Imagery

Passive Control Group

NO INTERVENTION

The participants in the Passive Control Group will not receive any intervention nor placebo session.

Interventions

Relaxation intervention session begins with diaphragmatic breathing, followed by Jacobson's progressive muscle relaxation, which involves the contraction and subsequent relaxation of the 16 muscle groups of the body (forearm, arm, upper forehead, eye, mouth, jaw and throat, neck, shoulder, chest, stomach, thigh, leg and foot). The contraction is performed for 7 seconds while the relaxation lasts for about 40 to 50 seconds. The relaxation of the foot muscle group is only performed on the healthy foot, because dressing and bandages may bandage the foot with the DFU, which together with the typical joint stiffness of the diabetic foot, make it difficult to perform. After muscle relaxation, begins the guided imagery focused on DFU healing. The patient is instructed to think about his/her current state of health and to imagine the DFU as a dark area and the healing relaxation as a light associated to pleasant sensations, which will focus on the foot with DFU to heal it.

Muscle Relaxation with Guided Imagery

This placebo consists on neutral guided imagery focused on themes of the patient's daily life before having DFU. Each session has a theme associated with the patient's life - family, work, friends and leisure. Initially, the patient is asked to think about an event related to the theme of the session of his/her choice, be it positive or negative, which occurred before patient has the current DFU. Then, questions are asked which allow a more detailed reconstruction of the event and the patient is asked to imagine according only to the instructions given. When the whole episode is remembered, the patient is asked to tell what he or she imagined/remembered in each of the questions given.

Masking Details
Eligible participants will be randomised into the three groups into blocks of variable size, multiples of three; and will be stratified according to: i) data collection site; ii) Chronic Renal Disease; and iii) Peripheral Arterial Disease; because they are factors of poor prognosis in the DFU healing (Ferreira et al., 2014). This procedure will be performed using an online random number generator, by a researcher external to the team involved in the implementation of this study, in order to ensure the concealment of the allocation of participants by the various groups (Pandis, 2012). After this procedure, it will not be possible to conceal the group to which the patient belongs from the researcher who will perform the psychological intervention. However, health professionals (doctors and nurses) will be blinded during the entire procedure, because they fill in the RESVECH 2.0, which assesses the DFU healing.

Intervention Model
PARALLEL
Model Details: This is a Pilot Randomised Controlled Study of a Psychological Intervention (Eldridge et al., 2016; Grant et al., 2018). This study will use a mixed-methods approach nested in a pilot 3-arm randomized control design. Qualitative and quantitative data will be collected in order to provide better understanding about the feasibility and acceptability of the relaxation intervention in patients with DFU. Participants will be randomised at a ratio of 1:1 for the three conditions - EG, ACG and PCG; and will be evaluated on the day of the first chronic DFU appointment or nursing treatment (T0), two months later (at the end of the intervention in EG and ACG; T1), as well as six months later (T2) in a follow-up evaluation. Participants from all three groups will undergo standard treatment for the DFU, according to the guidelines of the Portuguese General Health Direction (DGS, 2010) and the International Working Group on the Diabetic Foot (IWGDF, 2015).
