Product Details :

The Active-K is a motorized physiotherapy unit that delivers a unique mix of rehabilitation therapies through a single device. Combining the benefits of CPM (Continuous Passive Motion), CAM therapy (Controlled Active Motion) and the onboard protocols, the patient is able to regain coordination and reduce proprioceptive deficit.

Using the Active-K allows patients to regain painless mobility of hip and knee joints at an early post-operative stage and stimulates the healing process.

Additionally, the active component of the therapy unit is intended to enhance proprioception and functional stability (strength) as mentioned at an early stage and thus improve coordination following joint surgery.

The Active-K has the capacity to allow clinicians to perform therapeutic strengthening exercises by allowing muscular contractions using the following methods:

  • Concentric
  • Eccentric
  • Isokinetic
  • Isometric
  • Range of Motion
  • Extension/Flexion “Knee”: 10°/0°/120°
  • Extension/Flexion “Hip”: 0°/7°/115° Functions
  • “Passive” Mode
  • “Active” Mode
  • “Coordination” Mode Additional therapeutic benefits for patients:
  • Enhancement of joint metabolism
  • Prevention of joint stiffness
  • Promotion and regeneration of cartilage and damages ligaments
  • Faster hematoma reabsorption
  • Improved blood & lymph circulation
  • Prophylaxis for thrombus and embolism syndromes
  • Bridging the gap from passive motion to active training with resistive therapy during rehabilitation
  • Expedites coordination & sensory perception following surgery
