Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the experimental condition subjects received ReHand Tablet app as a home-based form of rehabilitation. A 4-week home exercise intervention was performed, which had to be carried out daily by the patient autonomously at home for at least 5 days per week, starting after baseline measurement, and beginning no more than 10 days after removal of immobilization or surgical intervention. The exercise program was individualized according to pathology (e.g. the program for those patients with distal radius fracture was different from the program for carpal tunnel release patients) and lasted approximately 25 minutes per day. ReHand is a Tablet application (Android and iOS) which has a battery of specific exercises for the recovery after a trauma injury to be done touching the Tablet screen. The adherence to treatment was monitored through ReHand dashboard.
Exercise example: Pinch exercise with the index finger, performing a controlled movement in a painless range guided by feedback during 25 seconds.

Rehabilitation
Comparator / control treatment
In the control condition subjects received the home exercise program on paper that is conventionally used in public hospitals (not available resource yet) to be done daily during 4 weeks. The exercise program was the conventionally prescribed one by the public service for all those pathologies and had a duration of 20-25 minutes. The exercises were focused on the mobility of the entire upper limb, with greater relevance of those exercises relating to the hand.
Exercise example: Contact each finger's pad with the thumb pad 15 times

Size= 660 patients.
Once the recorded data have been explored and refined, a descriptive statistical analysis will be carried out. The results derived from it will be expressed in number and percentage for the qualitative variables and centralisation measures (mean or median) and their corresponding dispersion measures (standard deviation or interquartile range) for the quantitative variables according to whether or not they follow a normal distribution (respectively).
Subsequently, a bivariate analysis will be carried out in which qualitative variables will be compared using contingency tables and Pearson's chi-square test, or Fisher's test (for tables in which there is at least an expected frequency of less than 5). To determine the existence of association between quantitative and qualitative variables, we will use the t-Student test or, if applicable, the Mann-Whitney U (non-parametric) if the qualitative variable is dichotomous or the ANOVA test or, if applicable, the Kuskal-Wallis test (non-parametric) if the qualitative variable is politomous (test for independent samples). To study the behaviour of two quantitative variables we will use techniques of
correlation analysis (Pearson or Spearman, according to their behaviour) and if the data allow it, multivariate study techniques will be carried out using regression techniques.
In order to compare the degree of improvement within each study group we will use repeated measurement tests such as the Student t test for related samples or, where appropriate, non-parametric tests for related samples according to the characteristics of the grouping variables. In case the results allow it, a subgroup analysis will be carried out according to the data obtained in the questionnaire carried out and valuing different grouping variables. We will use IBM SPSS Statistics 18 and EPIDAT 3.1 and 4.1; Significance levels below 0.05 (p<0.05) will be considered.

Summary
Brief summary
Traumatological injuries of the wrist, hand and fingers are one of the most common and one of the costliest. According to scientific evidence, program exercises are effective for the rehabilitation of this segment. However, the format of prescribing exercises on paper is inefficient, having a need for updating. ReHand is a Tablet application (Android and iOS) developed under the guidelines of various healthcare professionals (rehabilitators, hand surgeons, physiotherapists and occupational therapists) to enhance, through controlled active work, the dexterity and functionality of the wrist, hand and finger segment after a trauma injury. Subjects are selected through consecutive sampling, concretely patients over 18 years of age, no more than 10 days after surgery or removal of immobilization, with any of the following pathologies: distal radius fracture, 5th metacarpal fracture, carpal bone fracture, carpal tunnel syndrome surgically intervened, rhizarthrosis surgically intervened, and Dupuytren surgically intervened. In the experimental condition subjects received ReHand Tablet app as a home-based form of rehabilitation, while in the control condition subjects received the home exercise program on paper that is conventionally used in public hospital. The main hypothesis is that the use of ReHand is more effective than the conventional treatment used for these conditions. This is a multicenter study carried out in Virgen del Rocío and Virgen Macarena hospitals, and in San Juan de Dios Aljarafe Hospital. The overall trial start date was 25/04/2017 and the recruitment is expected to continue until 30/04/2019. During this time, results could be published. This study was supported by the Innovation Projects Grant #0143-2017 of the Health Council of Andalusian Government.
