Instructions for use for patients ReHand 2.1.0

Revision Level: version 2
Revision Date: May 06th 2022

Welcome to ReHand!

Before starting with the Instructions for Use, we welcome you to ReHand. ReHand is the first evidence-based digital Tablet solution for the rehabilitation of wrist-hand-finger segment affectation. ReHand offers a rehabilitation service customised to both the physiological characteristics of the patient, their condition and time of recovery, as well as for the healthcare professional -hereafter referred to as the health professional or prescriber- who prescribes and monitors.

These instructions are intended to help and describe the intended use for the user -hereinafter user or patient- to start their treatment with ReHand. Likewise, the app presents explanatory videos at the beginning of each exercise and audio instructions, so we recommend that you use the app with the volume of your tablet device turned on and watch the videos before performing each exercise. In case your doubts are not resolved by this document, please contact us at [email protected].

WARNING: Read these instructions carefully before using ReHand. To prevent its misuse, it is necessary to obtain a prescription from a healthcare professional so the exercise program can be properly adapted to the patient’s condition and monitored.

ReHand programme can be carried out remotely at home or face-to-face in-room , with or without the direct supervision of a healthcare professional, but always under their indication and prescription.

1. The concept of ReHand

ReHand is a therapeutic exercise programme for wrist-hand-finger segment trauma, orthopaedic or neurological conditions. 

ReHand complements conventional therapies, e.g. pharmacotherapy, physiotherapy, occupational therapy or hand therapy. For example, ReHand can be used to reduce waiting time before the start of face-to-face (either in the clinic or at home as a complement to face-to-face therapy), or to continue the treatment after the end of face-to-face therapy.

WARNING: if you feel pain or excessive fatigue while performing the exercises or after the use of ReHand, stop the exercise and consult your healthcare professional.

The specific exercises of the programme for each patient are prescribed by their healthcare professional. These exercises are performed directly by touching and tapping the touch screen of a tablet device. This enables: the continuous adaptation of the exercises to the evolution of the patient’s abilities, the integration of a multisensory perspective in the exercise, and finally, to have an additional option for the visualisation of the patient’s exercise performance. The exercises contain video, audio and text instructions.

ReHand provides the patient with graphical data about their performance in their therapy and their adherence rate, including motivational messages for the patient in order to achieve optimal adherence levels. In addition, ReHand allows the patient to fill in the clinical questionnaires and scales that their healthcare professional has set up for them.

Progress reports can be downloaded both by the patient from the ReHand app and by the clinician from the ReHand Dashboard.The ReHand programme can be performed at home or in the clinic, with or without the direct supervision of a doctor, physiotherapist or therapist. Unless otherwise instructed by a healthcare professional, the ReHand exercises must be performed daily, at least three days a week. The daily execution time of the exercise programme is usually between 20-30 minutes (time per therapy unit). The duration of use depends on the type of condition and is therefore determined by the health care professional, but the duration of use is usually a maximum of 3 months.

Therapeutic exercise is the core of ReHand’s action, which also seeks to integrate the sensorimotor system approach through multisensory feedback to achieve an effect not only peripherally on the injured tissue, but also at the level of the central nervous system. Furthermore, the continuous adaptation of each of the exercises to the patient’s capabilities allows, on the one hand, to include a challenging and motivating component in the execution of the therapeutic exercise and, on the other hand, that the exercise is continuously adapted to the patient’s capabilities at each moment of his or her recovery. 

ReHand, by providing the patient with a therapeutic exercise programme, falls within the guidelines and updated scientific evidence for the treatment of these disorders, with a multitude of clinical trials demonstrating the positive effect of therapeutic exercise programmes on these disorders. Thus, ReHand’s exercises have been designed following this evidence, and have undergone previous clinical trials, demonstrating their effectiveness.

According to the results of the clinical trials conducted and the existing scientific evidence, its use would preliminarily lead to an early improvement in clinical variables such as functional ability, dexterity or strength. It has also shown improvements in other related variables, such as early return to work and fewer physiotherapy, rehabilitation or surgery consultations.

5.1 ReHand app

At the beginning of the ReHand app, the patient will be requested to enter an access code provided by the prescriber of the exercise programme. Once logged in, ReHand app will ask the patient to add an email address and password to set up their account. In addition, your patient will be asked to enter their first name, last name and age, and to accept the terms and conditions of use, privacy policy and instructions for use. We encourage you to use “strong” passwords (passwords that use a combination of upper and lower case letters, numbers and symbols).

Once the initial account setup is complete, you will be able to use the ReHand app.

6. Treatment System (ReHand app)

6.1 Initial instructions

Initially, once registered in the application, the following “Program” page appears:

A pop-up appears with a warning of a new initial scale that can be found in the ‘Scales’ section.

TUTORIAL ICON

An information icon is also available on the top left of the “Program” menu. When you click on it, the initial instructions are shown. They will be displayed as you click on the “next arrow” button.

HAND SELECTION

At the top of the ‘Program’ page there is a button to select the hand you wish to view the programmed exercises for. If no exercise card appears on the screen, this means there is no exercise configured for that selected hand.

EXERCISE CARD

Each exercise is represented by a card where the type of exercise and hand to be treated is reflected in an image. The name of the exercise appears immediately below, followed by the finger/area.

DAILY REPETITIONS

To keep track of the repetitions made during the day, the crosses represent the number of daily repetitions to be made. As each repetition is performed, each cross changes to a blue tick.

LEVEL

Each blue circle represents the level of the exercise you are in. Therefore, as you perform exercises with a good score, the level of the exercise increases. On the other hand, if you perform  the exercises with a low score, the level decreases.

SPEED BAR

To level up in the exercises, it is necessary to achieve a score greater than 90 for each repetition as the speed bar increases.

Finally, we recommend activating the sound while using the application. If you have any doubts or problems, we recommend consulting the “FAQs (Frequently Asked Questions)” section by clicking on the “Account” button or to write to us at [email protected].

6.2. Exercises
