Lower limb continuous passive motion device SL1

kneeankleupper limb

A patented, portable active training apparatus designed to accelerate recovery after knee surgery by allowing patients to perform controlled, safe and pain‑limited active and passive knee exercises. The device supports personalized training with adjustable angle, strength and duration and can be used in multiple body positions.

Clinical Background

• Addresses osteoarthritis (OA) and knee osteoarthritis (KOA) where cartilage degeneration leads to pain, limited movement and reduced quality of life.
• High prevalence in older adults; intended to support rehabilitation and reduce disability caused by KOA.

Clinical Advantages

• Enables active and assisted passive flexion and extension exercises after knee operations (e.g., TKA) to improve range of motion and knee function.
• Patient-adjustable training angle, strength, intensity and duration to match individual condition and pain tolerance, preventing damage from excessive exercise.
• Economical, stable and portable with accurate running track and intuitive scale/angle indicators for objective progress monitoring.
• Supports coordinated lower-limb training with upper-limb assistance to improve active movement, limb muscle strength, cardiopulmonary function and proprioception recovery.

Clinical Application

• Main functions: Lower extremity joint range-of-motion training and muscle strength training around the knee joint.
• Applicable departments: Orthopedics, rehabilitation, geriatrics, traditional Chinese medicine.
• Applicable people: Postoperative knee rehabilitation, nerve injury rehabilitation, sports injury recovery and other indications requiring controlled knee mobilization.

Features

• Combination of active and passive training; simultaneous joint mobility and upper & lower limb muscle-strength training.
• Clear scale and training counter to ensure measurable training effects.
• Patient-controlled angle, strength and training duration for safe, repeatable daily sessions that reduce therapist time requirements.

Technical Advantages

• Elevation angle adjustable from 0° to 38°.
• Height adjustable from 7 cm to 49 cm.
• Lower-limb stroke adjustable from 0 cm to 65 cm to meet different training programs.
• Professional ankle and foot fixation protector with double internal padding for comfort and safety.
• Usable in both sitting and lying positions to accommodate different patient needs.
• No external power required; lightweight and portable for use in clinic or home settings.
