Description of intervention(s) / exposure
PainReApp Group

Individuals of three different chronic pain conditions will be randomly selected: chronic low back pain, fibromyalgia and diabetic neuropathic pain.

The intervention group will complete a program of exercise guided by a m-health system for 24 weeks. Previously, their doctors determined whether patients would be able to exercise regularly.

A program of 60 min, 3 times per week, aimed to improve the general conditioning of the patients will be performed, following the recommendations of the American College of Sports Medicine for patients with chronic pain. The daily session will be divided into the warm-up, aerobic training, strengthening and calm down.

- Warm-up: It will consist of 5 min. walking in a way that allows the patient to have a conversation.
- Aerobic training: It will consist of 10 to 20 min. walking so the patient can have a conversation, but having to stop and breathe once in a while.
- Strengthening: It will be focused on 7 exercises. a) squats, b) stiff-legged deadlifts, c) lateral pull-down, d) reversed flies, e) flies, f) unilateral rows, and g) lateral raise.
- Calm down: It will consist of stretching exercises. a) shoulders, b) triceps, c) chest, d) quadriceps, e) hamstrings, and f) back.

Patients will have a first face-to-face session in which the use of the smartphone app and the conditioning program will be explained. This session will be performed in the Hospital Universitario Puerta del Mar (Cádiz, Spain). Strengthening exercises will be performed using an elastic band. During the first session, a physiotherapist will explain how to manage the elongation of the elastic band to increase or decrease the resistance intensity. The general recommendation will be 70-80% 1 repetition maximum that allows the patient to perform 8-10 repetitions. These home exercise sessions will be approximately 60 min. depending on the level of the patient. The PainReApp m-health system will provide videos and descriptions of exercises to be performed. The adherence to the intervention will be monitored through the PainReApp application.

Comparator / control treatment
Control group

Participants randomised from the three conditions (chronic low back pain, fibromyalgia and diabetic neuropathic pain) to the Control Group will receive the same intervention, but in paper format. Their doctors determined whether patients would be able to exercise regularly and they follow the same exercise program for 24 weeks.

This group also will receive a first face-to-face session in which the conditioning program will be explained by a professional physiotherapist. They will get a document with photos and descriptions about the exercises to be performed. The adherence to the intervention will be self-reported by patients when they will attend to the follow-up sessions.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomization by computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Through the Epidat 3.1 module of assignment of subjects to treatments, with groups of equal size, two lists (for each condition) of 50 random numbers between 1 and 100 will be obtained, without repetition. They will be used to determine in advance the group to which each patient will belong according to their order of arrival. In case of exceeding this initially estimated sample size, the randomisation process will continue to make use of the "balanced group" strategy, in which the probability of inclusion in each group will be inversely proportional to the number of subjects already in that group, so that, by probability, both groups will grow in a balanced way.

Statistical methods / analysis
A descriptive analysis of the data will be carried out, showing their distribution in terms of absolute frequencies (n) and relative frequencies (%) in the case of qualitative variables, and central tendency (mean) and dispersion (standard deviation) measures, in the case of quantitative variables. The normality of the distributions of the quantitative variables will be checked by means of the Kolmogorov-Smirnov test. Differences between groups (intervention vs. control) will be analysed by t-Student tests in case of normality, or Mann-Whitney U tests otherwise. Differences over time between groups will be analyzed by mixed ANOVA (with corrections such as Pillai's Trace, Roy's Largest Root, Greenhouse-Geiser or Lower Limit in case some assumption such as normality or equality of variances fails), where the intra-group factor will be the time and the inter-group factor will be the intervention group. In all cases, the confidence level will be set to 95%. To know the factors associated with the evolution of pain intensity and health-related quality of life, GEE models will be used, where the dependent variables will be the NPRS score and the SF-12 dimension score. In both cases, the independent variables will be the time itself, the intervention group, the scores of the HADs and MOS, the amount of exercise and the socio-demographic variables. The use of GEE models contemplates the case of missing values, due to the longitudinal nature of the measurement of these scales. Quasi-likelihood estimators will be used to estimate the model parameters. The structure of the correlation matrix will be defined according to the common structures and in accordance with the nature of the data (Independence, Interchangeable, Self-Regressive or No Structure). In addition, the model will be validated with the assumptions associated with the technique. The analyses will be carried out with the IBM SPSSv.24 statistical package.
