Powered Knee Orthosis

First robotic knee orthosis with adaptable stiffness, which interprets the needs of the patient and provides the strength, mobility and stability necessary to be able to walk. Sensors provides biomechanical analysis of the patient’s gait and works to improve it.

Clinical benefits

Reduction in the recovery time of patients with total knee arthroplasty by 66% compared to conventional treatment.

Reduction of pain during the sessions and, consequently, a lower rate of attrition of the rehabilitation treatment, thus providing the patient with a maximum recovery.

Reduction of pain during sessions, thanks to the customization and adaptation of the exercises. This motivates patients to exercise the intervened area and consequently inflammation and pain are reduced.

Obtaining objective and standard data both in the initial evaluation of the rehabilitation and in the evolution. Identification of deviations both in angles and in force.

Personalization of the exercise for each patient and execution of the therapy with total precision and repetition.

Higher degree of recovery and satisfaction.

Features  MAK ACTIVE KNEE

Indications MAK ACTIVE KNEE

MAK Active Knee has CE clearance and indicated for use in gait rehabilitation in patients affected by hemiplegia or knee weakness. Currently tested successfully in:

  • Rehabilitation after total knee arthroplasty

MAK is currently under clinical trial for extending its use for:

  • Rehabilitation of brain damage (stroke)
  • Treatment of Multiple Sclerosis
  • Treatment of Muscular Atrophies
  • Treatment of Muscular Dystrophies
  • Assistance in cases of muscle weakness due to age

User requirements

  • Max weight 100 Kg
  • Contraindication: Osteoporosis, severe spasticity and skin conditions negatively affected by orthotics

Clinical Evidence

To date, 3 clinical studies have been conducted with the MAK exoskeleton.

Study at Aita Menni Hospital

  • Title: Assessment of the effect on gait related outcome measures for neurological patients (MAKNEURO)
  • Trial site: Aita Menni Hospital
  • Aim: The aim of this study was to observe if a user with a neurological impairment obtained better gait-related outcomes compared with not wearing the device. Whilst also assessing for AE´s.
  • Study Design: : Open label, non-comparative, Pilot study.
  • Sample Size: N-5 (x 4 stroke, x 1 MS)
  • Outcome Measures: 10MWT, G.A.I.T, QUEBEC 2.0.
  • Results: When using the MAK the following improved where observed; Gait pattern, Step length, Centre of Pressure (COP). No AE´s where noted.
  • No se aprecian AE.
  • Conclusion: MAK is safe to use for neurological patients with tolerance at acceptable levels. MAK shows promise in improving a patients gait whilst being worn. Further research is required to determine transferability and any carry over effect.

Lines of investigation

Study at Hospital Universitario La Zarzuela

  • Title: Marsi Active Knee
  • Trial site: Hospital Universitario la Zarzuela (Sanitas is part of Bupa)
  • Aim: To observe the feasibility of the use of MAK for the rehabilitation of the joint after the arthroplasty operation and if it reduces the recovering time compared to usual rehabilitation.
  • Study design: Pilot study
  • Sample size: N-10
  • Outcome measures: MRC Modified Muscular Force Scale, ROM, Perceiced pain (EVA), number of intravenous analgesia boluses needed, registration of the debit in the drainage, Post-operative inflammation by measuring the perimeter 10 cm from the upper pole of the kneecap, Timed Up and Go, 6MWT.
  • First Patient First Visit (FPFV) : 30/05/19

Study at Hospital Universitario La Paz

  • Title: : Study of the usefulness of the makv1 active knee device in the rehabilitation of patients after stroke.
  • Trial site: Hospital Universitario La Paz
  • Aim: To verify the viability of the MAKv1 device in a stroke rehabilitation program.
  • Study Design:Pre-post study
  • Sample size: N-26 Stroke <6months, motor alteration.
  • Outcome measures: 6MWT, 10MWT, 5TST, Time to step up and down stairs, QUEST2.0 partial.
  • First Patient First Visit (FPFV): : TBD
