1.1 Fields of application

1.3 Indications

The ARTROMOT® ACTIVE-K is a motorized physiotherapy unit. It combines the benefits of CPM therapy (= Continuous Passive Motion), post-operative mobilization, and CAM therapy (= Controlled Active Motion), neuromuscular training to reduce functional instability. With these features, it promotes rehabilitation by allowing both, continuous passive motion and, after initial therapy, controlled active motion of the knee and hip joints. The ARTROMOT® ACTIVE-K physiotherapy unit should not be considered as an exercise machine, but as a therapy unit for early mobilization, offering active exercising to promote coordination and preservation of functional strength at an early stage.

The physiotherapy unit is indicated in the treatment of most injuries and diseases of the knee and hip joints as well as in postoperative treatment after knee and hip joint surgery. Examples:

The ARTROMOT® ACTIVE-K physiotherapy unit is an important supplement to medical and therapeutic treatment for use in hospitals, clinics, general practices and rental services.

– endoprosthetic implants

1.2 Therapy objectives

Do NOT use ARTROMOT® ACTIVE-K on patients with:

– joint distortion and contusion – arthrotomy and arthroscopy procedures in combination with synovectomy, arthrolysis, or other intra-articular interventions – mobilization of joints in anesthetized patients – operative treatment of fractures, pseudoarthrosis, and osteotomy – cruciate ligament replacement or reconstruction

1.4 Contraindications

– acute inflammatory processes in the joints, unless on the order of a physician

CPM therapy with the ­ARTROMOT® ACTIVE-K is mainly used to prevent the negative effects of immobilization, to allow patients to regain painless mobility of joints at an early stage, and to promote healing and achieve a positive functional result. Furthermore, the active component of the therapy unit is intended to enhance proprioception at an early stage and thus improve coordination following joint surgery.

– spastic paralysis – unstable osteosynthesis

1.5 Secondary effects Currently, there is no evidence of desired or undesired secondary effects of CPM or CAM units.

Other objectives of therapy include: – improvement of joint metabolism – prevention of joint stiffness – promotion of the regeneration and healing of cartilage and damaged ligaments – faster hematoma/fluid resorption – improved lymph and blood circulation – thrombosis and embolism prophylaxis – bridging the gap between passive motion and active training with exercise machines during rehabilitation – enhancing coordination/sensory perception after surgery Supplied by EME Services Ltd

1. How to use the physiotherapy unit (Intended Use)

The motorized physiotherapy unit permits active and passive motion of the knee joint in the form of extension / flexion in the range of –10 – 0 – 120 degrees and of the hip joint in the form of extension / flexion in the range of 0 – 10 – 115 degrees The range of motion can be set very precisely in steps of 1 degree. Additionally, in the active mode, a resistance in the direction of motion or in the opposite direction can be set individually in the range from 1 kg to 30 kg in steps of 1 kg. Furthermore, the physiotherapy unit comes with special protocols to enhance proprioception, i.e., coordination, and functional stability at an early stage. These are some of the ARTROMOT® ACTIVE-K features: – anatomically correct setup – physiological movements – control pendant for precise adjustment of patient-specific therapy values – symbols for easy operation of the control pendant – chip card for storage of the programmed therapy parameters Biocompatibility Those parts of the ARTROMOT® ACTIVE-K that come into contact with the patient when the device is used as intended, are designed to fulfil the biocompatibility requirements of the applicable standards.
