Instructions for use ReHand 2.0.0

Revision Level: version 5

Revision Date: December 1st 2021

Welcome to ReHand!

Before starting with the Instructions for Use, we welcome you to ReHand. ReHand is the result of the teamwork of professionals from different specialities (hand surgeons, physiotherapists, engineers, doctors, occupational therapists…) which will allow you to carry out the treatment prescribed by your healthcare professional.

These instructions are intended to assist the user in starting their treatment with ReHand. The app also includes 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 turned on and watch the videos before performing each exercise. In case your doubts are not solved with this document, please contact us at [email protected].

WARNING: Read these instructions carefully before using the app. To prevent its misuse, it is necessary to obtain a prescription from a healthcare professional so the exercise program can be properly adapted to your condition and monitor you.

1. The concept of ReHand

REHAND APP is a rehabilitation app for the wrist, hand and finger segment that includes a battery of exercises that address the recovery of different functionalities of this segment, through a series of routes on the touchscreen of tablet devices. These routes through the screen are guided by circles, each one with a colour depending on the finger, that makes contact with the screen. Prior to each exercise, there is a double adjustment that allows the exercise to be adapted to the size of the hand and to the patient´s limitation.

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

Likewise, these exercises have a gamification system that makes the difficulty of the exercises increase as the patient obtains better scores when performing the exercises, increasing the speed of the exercises and decreasing the size of the circles. The exercises adapted to the limitation of each patient have been designed in accordance with current scientific evidence regarding the improvement of the functional limitation of the hand.

ReHand App also has a page of questionnaires and scales, where the patient periodically receives a series of questionnaires and scales relating to parameters such as functional ability or pain. In addition, ReHand App has a progress page on which statistics and graphs of patient adherence/performance are displayed and messages are given based on these, allowing patient motivation and generating continuous feedback on their evolution. At the same time, these statistics are sent to the therapist, so that the professional can periodically monitor his/her patient.

2. Intended Use

ReHand´s indications is hand-wrist-finger conditions. The scope of such indication includes: 

1.- WRIST AND CARPAL FRACTURES

2.- METACARPAL AND PHALANGES BONES FRACTURES

3.- NERVE PATHOLOGY

4.- NON-SURGICAL OPERATED SOFT TISSUE PATHOLOGY

5.- SOFT TISSUE SURGERY

6.- ELBOW PATHOLOGY

7.- DISLOCATIONS, CONTUSIONS, SPRAINS IN THE WRIST, HAND AND FINGERS

8.- POST-SURGICAL REHABILITATION

9.- NEUROVEGETATIVE PATHOLOGY

10.- RHEUMATIC PATHOLOGY

11.- NEUROLOGICAL PATOLOGHY

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.

3. Contraindications

— Any circumstance in which the exercise implies the interruption of the tissue healing process. Symptoms such as increased pain, erroneous movements, swelling or flushing, will be a determining factor in the interruption of the therapy.

— Presence of severe muscular or joint pain during the execution of your program or that is maintained beyond 24 hours after its execution.

— Acute infectious and inflammatory processes in the wrist-hand-finger segment undergoing therapy.

— Haematomas or other signs of traumatism appearance in the wrist-hand-fingers segment undergoing therapy.

Afterwards, 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 green 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 performs 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 to activate the sound while using the application. If you have any doubts or problems, we recommend to consult the ‘FAQs (Frequently Asked Questions)’ section by clicking on the ‘Account’ button or to write to us at [email protected].

4.2 Exercises

Furthermore, before carrying out the exercise, the following instructions are given, complementing the text with audio messages for execution.

A. START OF ADJUSTEMENT

When you click on an exercise card, you enter it and are given instructions on how to adjust the position. Before starting the adjustment, you will be given the opportunity to watch a video explaining the procedure.

B. EXPLANATORY VIDEO

The correct way to perform the adjustment and the exercise is described in the explanatory video.

C. POSITION ADJUSTMENT

During the first adjustment, a gif explaining how to adjust the position is displayed.

D. POSITION ADJUSTMENT II

In this first step, a position adjustment is performed. In this adjustment you have to place a certain hand-finger segment on the tablet screen and this position is recorded.

E. MOVEMENT ADJUSTEMENT GIF

During the second adjustment, a gif explaining how to make the movement adjustment is displayed.

F. MOVEMENT ADJUSTMENT

In this second step a movement adjustment is made. You must perform three times the movement of the exercise in a non-painful parameter. This non-pain range, optimal for the execution of the exercise, is recorded, and will be used later for the execution of the exercise.

G. EXERCISE EXECUTION

The exercise is carried out by moving or tapping on the screen, in the range configured by the movement adjustment. The exercise is timed and a performance score is reported based on how well the exercise was performed.

H. EXERCISE RESULT

At the end of the exercise, you will be informed of the score obtained in the exercise.

4.3 Progress

Clicking on the ‘Progress’ icon shows the page of the work carried out, where all the exercises performed are represented in a progress chart over time and each colour block corresponds to one of those exercises. Clicking on the blocks displays the name of each exercise, the hand related to it, the number of repetitions performed, and a dashed line at the top, representing the number of daily repetitions expected throughout the treatment.

The percentage of adherence is calculated from the number of expected and performed repetitions, and shown next to the feedback messages of the application itself.
