“X-iser engages vestibulospinal afferents
as well as activating all musclespindle cells of the
intrinsic spinal muscles and the joint proprioceptors ofthe spine to create a massive afferent barrage to the cerebellum and
thenthe frontal cortex.
A higher functioning cerebellum regulates thecardiopulmonary centers of the pons because thecerebellum is anembryological out-pouching of the pons. A higher functioning cortex
willinhibit the temporal lobes and the HPA
(hypothalamic-pituitary-adrenal) axisto shut off
the stress response.
- Decreases sensitivity to pain - Activates extensors over flexors (better posture) - Increases digestion - Increases immune system - Improves mood."

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

Incorporating The X-iser® Machine and Sprint Interval

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
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
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
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
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.

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
