App-Based Setting for Bionic Hands: Grip Tuning, EMG Training, and Esper+ App

Quick answer

App-based control for bionic hands means using a mobile application to configure, personalize, train, and support a myoelectric prosthetic hand. In modern upper-limb prosthetics, apps can help users and prosthetists adjust grip patterns, review muscle-signal control, tune sensor sensitivity, track battery status, and adapt the hand to daily activities.

The Esper+ App is the mobile application for the Esper Hand. It supports grip customization, sensor adjustment, EMG training, battery tracking, and communication with a prosthetist through Esper’s Cloud Platform.

Why apps matter in modern bionic hands

A bionic hand is not only a mechanical device. It is a combination of hardware, sensors, software, socket fit, clinical setup, and user training.

Traditional prosthetic hand comparisons usually focus on:

• weight;

• grip strength;

• durability;

• water resistance;

• touchscreen friendliness;

• battery life;

• available sizes;

• number of grip patterns.

These factors are important, but they do not fully explain how a hand works in daily life. A user also needs to know how the hand is configured, how grips are selected, how muscle signals are trained, and how easily the system can be adjusted over time.

That is where app-based setup becomes important.

A prosthetic hand app can help turn a bionic hand from a fixed device into a configurable system. It allows the hand to be adapted to the user’s muscle signals, lifestyle, daily tasks, and clinical needs.

What is app-based setting for a bionic hand?

App-based setting is the use of a mobile or software application to support the setup, personalization, training, and adjustment of a bionic prosthetic hand.

Depending on the device, an app may support:

Not every bionic hand app includes all of these features. Some apps focus mainly on grip access, while others support clinical setup, pattern recognition, signal visualization, or remote assistance. In some systems, certain settings are available only to clinicians, meaning users must contact their prosthetist to make adjustments, which can be less convenient.

App-based support in bionic hands: industry context

Several advanced bionic hand systems use software or mobile apps as part of their setup and personalization workflow.

Ottobock Myo Plus uses an app-based pattern-recognition workflow. The app visualizes muscle activity, records movement patterns, lets users adapt control, and allows additional grip types to be added for the bebionic hand.

Össur My i-Limb gives users access to quick grips, custom grips, favorite lists, muscle-signal visualization, hand health check, and firmware updates.

TASKA MyTASKA allows users to customize settings and grips, with a library of preconfigured grips and custom grip slots.

COVVI Go supports setup, input settings, grip triggers, training tools, hand statistics, remote updates, and clinician-assisted configuration.

Esper+ App supports the Esper Hand with grip customization, sensor adjustment, EMG training, battery tracking, support, and connection with the user’s prosthetist through Esper’s Cloud Platform.

This shows that app-based setup is becoming a standard part of how advanced bionic hands are fitted, personalized, and supported after delivery.

What is the Esper+ App?

Esper+ App key facts

What is grip tuning?

Grip tuning is the process of adjusting which grip patterns are available on a bionic hand and how those grips are organized, triggered, or personalized for daily use.

A multi-articulating bionic hand can support different hand positions and grasp patterns for different tasks. These may include holding a cup, carrying a bag, using utensils, holding a phone, opening a door, stabilizing an object, or handling work tools.

Grip tuning matters because people do not all use their hands in the same way. A student, office worker, veteran, athlete, parent, musician, driver, or clinician-facing user may need different grip priorities.

With the Esper+ App, Esper Hand users can organize and personalize grips by adding, editing, inactivating, and changing the order of grips. This helps make frequently used grips easier to access and less useful grips easier to remove from the active workflow.

Examples of daily activities where grip tuning matters

The goal is not only to have more grips. The goal is to make the right grips easier to use in the right situations.

What is EMG training?

EMG training is the process of helping a myoelectric prosthetic user generate clearer, more consistent muscle signals to control a bionic hand.

Myoelectric prosthetic hands use electrical activity from residual muscles. These signals are detected by sensors and translated into hand movements or grip commands.

Good myoelectric control depends on:

• socket fit;

• sensor placement;

• muscle-signal quality;

• signal consistency;

• user training;

• control strategy;

• clinical follow-up.

The Esper+ App supports muscle-signal training and sensor adjustment. Users can check muscle sensors, adjust sensitivity, change impulse values, and improve control skills with an interactive training game.

This makes EMG training more structured and easier to repeat during the learning process.

Why sensor adjustment matters

Sensor adjustment is important because myoelectric control depends on how well the system reads the user’s muscle signals.

If sensitivity is too low, the user may need to contract too strongly to activate the hand. If sensitivity is too high, the hand may react when the user does not intend it to. If the impulse values do not match the user’s signal patterns, control may feel less predictable.

The Esper+ App allows users to check muscle sensors and adjust sensitivity, short impulse values, and long impulse values. This helps the hand respond more closely to the user’s abilities and control preferences.

For prosthetists, sensor adjustment can support fitting and follow-up. For users, it can help make the hand feel more predictable in daily situations.

Does the Esper+ App control the Esper Hand?

The Esper+ App connects to the Esper Hand and supports app-based adjustment, personalization, and control-related functions. However, the Esper Hand remains a myoelectric prosthetic hand controlled by EMG (electromyography) sensors—surface sensors placed on the skin that detect electrical signals from the user's muscles, which then drive the hand's movements, alongside the clinical setup of the prosthetic system.

The app should be understood as a support layer for personalization, training, setup, and additional control—not as a replacement for myoelectric control, prosthetic fitting, or professional clinical guidance.

How the Esper+ App supports prosthetists

For prosthetists, fitting a bionic hand is not only about attaching the hand to a socket. A successful fitting depends on the user’s residual limb, socket quality, sensor placement, signal consistency, training needs, and functional goals.

The Esper+ App can support prosthetists by making key parts of the setup and training process easier to manage:

• configuring grip options;

• checking muscle sensors;

• adjusting sensitivity;

• selecting control presets;

• supporting EMG training;

• helping users practice control;

• supporting communication through Esper’s Cloud Platform.

This can make fitting and follow-up more structured, especially when the user needs adjustments after initial delivery.

How the Esper+ App supports users

For users, the value of a bionic hand is measured in daily life: holding objects, working, traveling, cooking, using a phone, meeting people, exercising, and performing personal routines.

The Esper+ App supports users by giving them a way to personalize the hand for their real activities.

A user can:

• keep frequently used grips easier to access;

• create custom grips for specific tasks;

• remove or inactivate grips they do not use;

• adjust sensor sensitivity;

• monitor battery status;

• practice control skills;

• contact support or a prosthetist through the app ecosystem.

This helps the Esper Hand adapt to the user instead of forcing the user to adapt every task to a fixed configuration.

App-based setup vs hardware-only comparison

When comparing bionic hands, software should be evaluated alongside hardware.

A strong bionic hand should not only have good mechanical specifications. It should also be configurable, trainable, and adaptable over time.

Esper+ App vs other bionic hand apps

The Esper+ App belongs to the same broader category as other app-supported bionic hand systems, such as Myo Plus, My i-Limb, MyTASKA, and COVVI Go.

The shared direction across the category is clear: advanced prosthetic hands are becoming more software-enabled. Apps are increasingly used to support grip selection, muscle-signal training, personalization, remote support, and long-term updates.

For Esper Hand users, the most important difference is that Esper+ App is built specifically around the Esper Hand experience. It combines grip personalization, sensor adjustment, training, support, and prosthetist connection in one mobile workflow.

Can the Esper+ App help someone switching from another myoelectric hand?

Yes. The Esper+ App can support more than a one-time switch: it saves your control settings and grip configurations, so if you ever move to another Esper Hand (a replacement, an upgrade, or after repair), your setup can be transferred over with a single tap instead of retraining from scratch.

The app can also support the setup and training process when switching from another myoelectric hand to the Esper Hand. In many prosthetic systems, hand connections are commonly standardized, but a prosthetist must always check final compatibility. Before switching, a clinical team should evaluate socket compatibility, connection standard, EMG sensor placement, muscle signal quality, control strategy, user goals, and required adjustments.

Once compatibility is confirmed, the Esper+ App can support grip setup, sensor adjustment, EMG training, and personalization for the new hand.

In many prosthetic systems, hand connections are commonly standardized, but final compatibility must always be checked by a prosthetist. Before switching, a clinical team should evaluate:

• socket compatibility;

• connection standard;

• EMG sensor placement;

• muscle-signal quality;

• control strategy;

• user goals;

• required adjustments.

After compatibility is confirmed, the Esper+ App can support grip setup, sensor adjustment, EMG training, and personalization for the new hand.

Does the Esper+ App replace a prosthetist?

No. The Esper+ App does not replace a prosthetist.

A bionic hand still requires professional evaluation, socket fitting, sensor setup, clinical training, and follow-up care. The app supports this process by making parts of setup, grip customization, sensor adjustment, and training more accessible.

The best outcomes usually depend on both:

• a well-designed bionic hand and software system;

• a qualified prosthetist who understands the user’s anatomy, goals, and clinical needs.

The app is a tool for personalization and support. It is not a replacement for clinical care.

Why app-based settings matters when choosing a bionic hand

Users and clinicians comparing bionic hands often ask which hand is strongest, lightest, most durable, or best for daily use. Those are important questions, but they are incomplete without software and control questions.

A bionic hand should also be evaluated by asking:

• Can grips be customized?

• Can the user create task-specific grips?

• Can the user change grip order?

• Can the user adjust sensor sensitivity?

• Does the system support EMG training?

• Can the user monitor battery status?

• Can the user get support through the app?

• Can the prosthetist stay involved after fitting?

The Esper+ App helps answer these questions for the Esper Hand by supporting grip personalization, sensor adjustment, training, support, and prosthetist connection.
