Physical Rehabilitation
The X-iser Machineā„¢ is a superb rehabilitation tool
Knee Rehabilitation

* Closed kinetic chain exercise (portability allows non-weight bearing and weight bearing use) 

* Non-impact therapy with patented non-rebound smooth hydraulic system

* Very easy to step on to and allows only an 8 inch step height through a safe range of motion

* Adjustable resistance with unilateral capabilities and responsive to force exerted

* Strengthens both agonist and antagonist muscles, thus enhancing neuromuscular coordination
  and proprioception required during functional activities

* Various levels of progressive rehabilitation techniques (i.e. seated exercises, standing with parallel bar assistance,
  hands-free use, and advanced techniques for athletes)

Lumbar Stabilisation 
* Promotes balance and improved posture through strengthening of the deep intrinsic stabilisers and
  incorporation of the neutral pelvic position

* Low stress on back
Clinical Application & Benefits
* Therapeutic muscular strength and conditioning

* Cardiovascular conditioning

* Neuromuscular conditioning

“X-iser engages vestibulospinal afferents as well as activating all muscle spindle cells of the intrinsic spinal muscles and the joint proprioceptors of the spine to create a massive afferent barrage to the cerebellum and then the frontal cortex.

A higher functioning cerebellum regulates the cardiopulmonary centers of the pons because the cerebellum is an embryological out-pouching of the pons. A higher functioning cortex will inhibit the temporal lobes and the HPA (hypothalamic-pituitary-adrenal) axis to shut off the stress response.

- Decreases sensitivity to pain
- Activates extensors over flexors (better posture)
- Increases digestion
- Increases immune system
- Improves mood."

Minimal Clinic/Training Room Space Required

* Portable design (folds to 20.5"x13"x4" and weighs only 14 pounds) also enables the unit to be taken home
  (purchased or rented from the clinic) increasing the time spent rehabilitating the injury.


 "A few years ago, following ACL reconstruction on my right knee, it took a full year before I played full contact rugby.  However, after the same reconstructive surgery on my left knee last year, I was able to play full contact rugby after only four and a half months.  The only difference in my rehab was the use of the X-iser machine.  As well as the amazing functional rehab the unit provides, the portability and convenience of the Short Bout Exercise Program allowed me to significantly increase the time put in to rehabilitating my knee.  Without a doubt, the dramatic difference in my rehab time between my two ACL reconstructions can be attributed to the X-iser Machine."

 ACL Rehabilitation Incorporating The X-iser® Machine and Sprint Interval Training
      By Mark J. Smith, Ph.D.


Closed Chain ACL Rehabilitation with New York Jets Linebacker Marvin Jones

Rehabilitation after anterior cruciate ligament (ACL) reconstruction has become more and more aggressive over the last two decades.

The keys to any rehabilitation program are to reduce postoperative swelling, achieve full extension, maintain patella mobility, regain
quadriceps control and minimise patellofemoral symptoms.

Most orthopedic surgeons, therapists, and athletic trainers agree that closed chain exercises are beneficial in ACL rehabilitation. Closed chain exercises minimise patellofemoral stress, stabilise the tibiofemoral joint, and reduce anterior translation of the tibia on the femur.

High intensity exercise of short duration has numerous benefits to muscular development. These include stimulation of human growth hormone, an activator of muscle growth, and utilisation of both type I and type II muscle fibers.

Using The X-iser® Machine, Merrick J. Wetzler, M.D. (South Jersey Orthopedic Associates, Voorhees, NJ) and Thomas E. Maxwell, MA, A.T.C. (Athletic Department, Rutgers-Camden University, Camden, NJ) conducted a pilot study incorporating Sprint Interval Training (SIT – intermittent 60-second high intensity exercise) into a standard aggressive ACL reconstruction rehabilitation protocol.

Weighing in at only 14 pounds, the X-iser permits closed kinetic chain exercise using a smooth non-rebound hydraulic system that minimises impact and joint reactive forces thereby reducing stress across the patello-femoral joint.

In addition, the adjustable resistance and independent responsiveness of each foot pedal allows less resistance for the operative limb during initial rehabilitation.

Without handrails the machine also enhances neuromuscular coordination and proprioception required during functional activities. Further the portability of the machine enables increased rehabilitation via in-home therapy.

The preliminary study consisted of eight athletes, who under went sub-acute ACL reconstruction (> six weeks post injury) using autologous bone-patella tendon-bone.

There were five females and three males (average age - 19.3 years). All began rehabilitation within three days post-op.

In addition to the standard protocol they began rehabilitation on the X-iser® Machine in a seated position as soon as 60 degrees of flexion was achieved.

Once the subjects had quadriceps control and could do a straight leg raise they began using the X-iser® Machine in a specialised standing position (go to “Demos” to view “Short Burst Stepping”). Initially subjects supported themselves using parallel bars, a table, or a walker.

When the athletes were comfortable on the machine they utilised a doorway for balance and support, but only if necessary. The athletes began with four, 30-second intervals at a sub-maximal effort and progressed to 1-minute intervals at maximum effort.

Once independent with the machine, the subjects began home-based SIT that consisted of four, 1-minute intervals at maximum effort with at least 30-minutes rest between intervals.

At four weeks an additional interval-training program was incorporated into their rehabilitation in the training room. The athletes maintained the home based SIT program on the other days.

All athletes achieved independent use of the machine by three weeks and had excellent compliance with the machine.

At 12 weeks full range of motion was achieved & all girth measurements were within 2.5 cm of the uninvolved thigh.

Isokinetic testing was within 20% of the uninvolved knee at 16 weeks.

Subjective fitness level was excellent at 12 weeks and none of the athletes complained of patellofemoral pain at six, 12 or 24 weeks.

A significant amount of the quadriceps hypertrophy and strength was attributed to the unique hydraulic system and specialised form.

Together they obtain a simultaneous concentric and eccentric contraction of the opposing legs resulting in no half-cycle recoveries typically seen with other stepping activities. This study and numerous case studies have demonstrated cost effective benefits to ACL rehabilitation and overall cardiovascular fitness using the X-iser® Machine.

The size and portability of the unit, along with its unique hydraulic system, also make it an excellent tool for the rehabilitation of other orthopedic conditions such as the rehabilitation of the ankle, hip and shoulder. It can further be used for the rehabilitation of conditions that have compromised balance. The machine has been used by industry professionals for rehabilitation since its inception into the marketplace in the early 1990s.

"The X-iser Machine provides safe, effective closed kinetic chain and aerobic conditioning for a variety of conditions. Its portable capabilities make it an excellent choice for home exercise programs for our ACL patients.”
