For individuals with upper-limb amputations, everyday life presents countless challenges.
Even the simplest actions — like grasping an object or opening a door — can be difficult.
Myoelectric prosthetic hands are changing this reality.
By combining technology with human intent, they support hand movement and independence, helping users reclaim control over daily life.
Thanks to advances in Artificial Intelligence (AI) and Electromyography (EMG),
modern prosthetic hands are becoming more intuitive, accessible, and personalized than ever before.
At Refind Inc., we specialize in myoelectric prosthetics designed around the needs of real users.
In this post, we’ll explore how prosthetic hands are transforming rehabilitation — and how Refind’s technology is shaping that change.
A Partner in Motion: How Myoelectric Hands Work
Myoelectric hands detect electrical signals from muscles (EMG) to interpret a user’s movement intentions,
allowing natural, fluid hand motions to follow.
This enables users to perform essential tasks — holding a pen, eating a meal, or using an electronic device —
while also helping restore hand strength through repetitive exercise and training.
EMG technology analyzes muscle signals in real time to control fine finger movements,
and AI continuously learns from these patterns, refining motion accuracy with every use.
More than just an assistive device, a myoelectric hand offers independence, confidence, and dignity.
Refind’s Myoelectric Hand Solutions
Refind designs every product with user comfort and usability in mind.
The OHand utilizes up to eight EMG channels to reproduce complex hand motions with precision.
Users can perform daily actions such as holding a cup or turning a doorknob naturally and efficiently.
The OHandLite, weighing only 363.5g, provides simple two-channel control for lightweight, all-day comfort.
Both models offer intuitive operation, helping users adapt quickly to daily routines.
Motion Modes Based on Thumb Position
Refind’s hands allow flexible mode changes depending on thumb orientation:
•
Lateral Mode: Enables Fist, Mouse, Key Grip, Pointing, Column, Plate, Salute, and Chopstick movements.
•
Opposition Mode 1: Allows Pinch and Power Grip modes.
•
Opposition Mode 2: Enables Three-Finger Grip, Power, Lift, and Hold movements.
These adaptive control schemes let users perform a variety of motions suited to real-world tasks.
Beyond the Hand: Refind’s Rehabilitation Solutions
Refind also develops assistive systems that complement prosthetic use and upper-limb rehabilitation.
•
ORE-3000 (Wearable Upper-Limb Exerciser): Supports elbow motion during recovery.
•
OYFM-7000 (Finger Exercise Device): Aids finger mobility with Passive, Assistive, and Active training modes.
•
Dynamic Arm Support: Provides 3D movement assistance and adjustable support for daily activities and therapy.
These devices are designed for both clinical and home-based programs,
enhancing the practicality and integration of myoelectric hands in everyday life.
From Rehabilitation to Real Life
Prosthetic hands play a crucial role in both therapy and daily living.
In rehabilitation centers, specialists use Refind’s OHand to train patients in essential grasping movements —
helping them gradually relearn actions they once took for granted.
At home, users employ their prosthetic hands for tasks such as eating or operating electronic devices,
regaining independence step by step.
One therapist noted,
“Myoelectric hands accelerate patient recovery and empower them to return to daily life — they’re more than tools; they’re enablers of freedom.”
Through a blend of accessibility, precision, and practicality, Refind’s solutions are improving quality of life for many.
The First Step Toward a Better Everyday
A myoelectric hand is more than technology — it’s a bridge connecting motion and life.
At Refind, we’re building that bridge with user-centered innovation, helping individuals regain independence and confidence.
