Recover mobility and confidence with the Artromot-S4, a Continuous Passive Motion (CPM) device engineered for anatomical precision in shoulder rehabilitation. Designed to support patients through the critical phases of postoperative recovery, this system mimics the natural mechanics of the human shoulder to restore range of motion effectively. By combining advanced motorized technology with ergonomic design, the Artromot-S4 ensures that therapy is not only effective but also comfortable, allowing for a personalized rehabilitation experience that adapts to the specific needs of every patient.

The Artromot-S4 is not only beneficial for postoperative recovery, but it also has other applications in the field of physical therapy. Its advanced motorized technology and ergonomic design make it a valuable tool for treating a variety of shoulder injuries and conditions, such as frozen shoulder, rotator cuff injuries, and shoulder dislocation.

Key Features and Benefits

Intuitive Touchscreen Control: The handheld controller features a bright display with clear, descriptive icons, allowing medical professionals to program exact motion ranges directly. This simplifies the setup process, ensuring the therapy protocol matches the patient's specific needs without complex menu navigation.
Comprehensive 3-Motor Movement: Three separate motors work in unison to cover all physiological movement axes. Whether the therapy requires anteversion and retroversion, adduction and abduction, or internal and external rotation, the device handles it with precision. It even accommodates extension and flexion (elevation) with the arm either extended or flexed.
Enhanced Patient Safety: Safety is paramount during automated therapy. The adaptive load reversal feature detects resistance—such as a muscle spasm—and automatically reverses the motion to protect the patient from pain or injury. The sensitivity of this feature can be adjusted to suit individual pain thresholds.
Quick and Easy Conversion: Maximizing efficiency in a clinical setting is vital. The Artromot-S4 offers clear user guidance for converting the device between left and right shoulder treatments, significantly minimizing downtime between patient sessions.
Optimized Comfort and Stability: The reinforced armrest provides a secure, stable platform for the patient's arm. With fully adjustable width and height settings, the device ensures a custom fit for patients of varying sizes, enhancing comfort during longer therapy sessions.

Comprehensive Range of Motion

The Artromot-S4 is designed to handle complex shoulder movements essential for full recovery. Its multi-axis system supports:

Anteversion & Retroversion: Controlled forward and backward movement.
Adduction & Abduction: Safe movement of the arm toward and away from the body.
Internal & External Rotation: Crucial rotational therapy for restoring functional reach.
Extension & Flexion (Elevation): Vertical movement with the arm either extended or flexed.
PNF & Wave Exercises: Specialized movements that combine axes to simulate natural physiological patterns, promoting better neuromuscular re-education.

Patient Safety and Comfort

Safety is paramount in post-operative care. The Artromot-S4 features a sturdy, reliable design that stabilizes the patient during use, minimizing the risk of incorrect positioning. The handheld programming unit allows for precise control over speed, range of motion, and force, ensuring the therapy remains within comfortable limits. Additionally, the integrated patient chip card stores individual treatment data, allowing therapists to monitor progress and adjust protocols accurately without manual logging errors.

Indications for Use

This device is suitable for a wide range of post-operative and non-surgical conditions, including:

Rotator cuff repairs
Total shoulder replacement
Frozen shoulder (adhesive capsulitis) release
Fracture stabilization and fixation
Acromioplasty and decompression surgery

Experience a rehabilitation tool that combines clinical precision with user-centric design, helping you regain strength and range of motion effectively.

Types of CPM Devices

Continuous Passive Motion devices come in a variety of types, each with their own unique features and benefits. Here are some common types of CPM devices that you may encounter in clinical settings:

Handheld CPM Devices: These compact and portable devices are designed to target specific joints such as the wrist or hand. They are lightweight and easy to operate, making them ideal for patients who require mobility during their rehabilitation process.
Tabletop CPM Machines: These larger machines are commonly used for major joints like the knee, shoulder, or elbow. They typically have adjustable settings and can accommodate a wide range of motion patterns.
Motorized CPM Machines: These machines are powered by a motor and can continuously move the joint in a controlled manner. They are often used for post-surgery rehabilitation and can help improve range of motion and reduce stiffness.
Gravity-Assisted CPM Machines: These machines use gravity to assist with joint movement, making them suitable for patients who have limited muscle strength or range of motion.
Passive vs Active CPM Machines: Passive CPM machines move the joint without any effort from the patient, while active CPM machines require some level of patient participation. The type of machine recommended will depend on the specific needs and abilities of the patient.
