170K1 FreeWalk

FreeWalk
Reference number 170K1
Function Stance Control Orthoses
Movement with swing

The FreeWalk orthosis can give patients with neurological indications new confidence while walking. It provides support even if a partial loss of muscle function has made it impossible for them to stabilise the knee joint in the anterior-posterior direction on their own.

  • The fact that the orthosis joint is locked during the stance phase and unlocked during the swing phase results in a gait pattern that is as natural as possible:
    • The orthosis system unlocks automatically when the user extends his or her knee shortly before the toes leave the ground while walking, prompting dorsiflexion of the ankle.
    • This allows the patient to flex the leg and let it swing through freely.
    • The orthosis joint locks automatically when the knee is extended prior to heel strike.
  • The FreeWalk features a manual lock release, which the orthosis wearer can use when sitting, for example.
  • The orthosis, which is simultaneously lightweight and stable, lightens the load on the back, hips and knee joint through its functionality.
  • There are numerous therapeutic benefits for users with paralysis: contractures and joint damage caused by immobilisation can be reduced, and muscle atrophy can be reduced. Cardiovascular ability can be retained for everyday activities.

Indications, how it works, features and benefits
Function Stance Control Orthoses
Indications Treatment with the FreeWalk orthosis is indicated for pareses and paralyses of the muscles and muscle groups of the lower limb. These may develop in the context of the following underlying diseases: Central nervous system disorders,
Condition following a stroke,
Condition following brain tumours,
Condition following encephalitis/brain abscesses,
Condition following serious craniocerebral trauma (CCT),
Multiple sclerosis,
Ataxia in the context of diseases involving the cerebellum (sporadic delayed atrophy of the cerebellar cortex, inherited cerebellar ataxia),
Diseases affecting the peripheral nervous system,
Radicular syndromes (for example, condition following spinal disc herniation, radiculitis and poly[neuro]radiculitis, Guillain-Barré syndrome),
Condition following lesions of the lumbar and sacral plexuses,
Peripheral nerve lesions (e.g. femoral nerve, sciatic nerve, tibial nerve, obturator nerve, superior and inferior gluteal nerves),
Polyneuropathy (e.g. asymmetrical diabetic polyneuropathy, alcoholic neuropathy, parainfectious and paraneoplastic polyneuropathy),
Diseases of the spinal cord,
Condition after spinal cord injury (e.g. incomplete paraplegia),
Incomplete hemispinal cord syndrome (Brown-Séquard syndrome),
Condition following spinal cord tumours and spinal meninges tumours,
Condition following transverse myelitis, abscesses,
Progressive spastic spinal paralysis (Erb-Charcot-Strümpell),
Amyotrophic lateral sclerosis (ALS),
Progressive spinal muscular atrophy,
Condition following acute poliomyelitis,
Post-polio syndrome,
Degenerative diseases (such as spinal stenosis, stenosis of the intervertebral foramen, spondylolisthesis),
Abnormalities of the spinal cord (such as vertebral arch defects with spondylolisthesis, spina bifida cystica, meningocele, myelomeningocele),
Funicular myelosis,
Syringomyelia,
Neural muscular atrophy,
Anterior spinal artery syndrome,
Affection of the muscles (myopathies),
Progressive muscular dystrophy,
Condition following polymyositis/dermatomyositis,
Other myopathies (also in the context of other underlying diseases such as Cushing’s myopathy),
How it works In contrast to the gait cycle of a healthy person, patients whose knee stabilising muscles do not function adequately require an orthosis to stabilise their knee joints. The FreeWalk orthosis provides stability only in the phase where it is needed. The swing phase is not compromised. Between heel contact and toe-off, i.e. as long as the foot is bearing weight on the ground, the FreeWalk orthosis stabilises the knee joint and supports the knee stabilising muscles. During the entire stance phase, the orthosis remains locked. The orthotic joint only releases the knee joint for the swing phase, between the terminal stance phase and the pre-swing phase.
Features & benefits Due to the low weight and the functionality of the FreeWalk orthosis, significantly less torque affects the knee joints of both legs. As a result, the mechanical stress is lower and the risk of osteoarthritis reduced. Gait analyses have shown that users require less oxygen and thus expend less energy with the FreeWalk. This creates cardiovascular reserves for greater physical performance. The FreeWalk is:
Lightweight,
Secure in the stance phases, like locked orthoses,
Movable during the swing phases, due to the disengaging of the orthotic knee joint (thus making the user’s gait pattern very similar to a physiological gait pattern),
Easy to put on and off thanks to frontal pads and handy quick-release closures,
Cosmetically inconspicuous,
Additional benefits,
Reduced formation of pressure points as a result of less skin contact and/or fewer rubbing points,
Quick exchange of worn parts,
Individual fabrication,
No medial joint interferes when sitting or walking,
Comfortable sitting thanks to flexible straps

The FreeWalk can be ordered quickly and easily online or by mail with a few measurements and outline drawings The tool kit and datasheets are needed for the dimensions. You can rent a test orthosis from us to carry out a functional test on your patient. Please contact our customer service for further information.
