Designed specifically for rehabilitation and retraining of gait for patients with neurologic and
orthopedic gait dysfunctions, the Biodex Gait Trainer 2 provides both the audio and visual feed-
back needed to progress patients quickly and safely to normal ambulation.
The Gait Trainer 2 is easy to use. The clinician need only select the patient’s age and height for the
treadmill to automatically calculate the exact speed needed to achieve desired step cycle. The
rhythmic movement and the audio feedback provide patients with added stimulus for retraining
of neural pathways to improve gait pattern.
The Gait Trainer 2 promotes correct stride length for early phase patients. By starting out slowly
(with the zero starting speed and small .1 step cycle speed increments) it is possible to manually
position the patient’s lower extremities in the desired patterns for gait, thus reinforcing the prop-
er techniques early in the rehabilitation process. As the patient progresses, correct stride length is
coupled to the correct step cycle. When belt speed is increased, the patient must either take longer
strides or more strides to stay on target. Normative data allows clinicians to compare patient
progress to baseline norms.
Of course, the Gait Trainer 2 can also be used for many other rehabilitation treadmill applications.
In treadmill mode, its unparalleled speed control, durability, incline and decline in both forward
and reverse directions, digital feedback, low profile, and choice of handrail configurations make
it the ideal choice for virtually any patient young or old.
The Biodex Gait Trainer 2 comes with a printer which is easy to install and resides on the printer
stand. Options include -3 to 12% incline/decline (ideal for work with back, posture, lumbar spine
and patella patients,) and a choice of handrails.
1. INTRODUCTION
—1-1 — INTRODUCTION
!
The following clinical considerations should be observed for all patients who exercise on the
Biodex Gait Trainer 2. Additional clinical considerations, specific to gait training, are provided in
the chapter titled: Clinical Applications and References.
1. All patients should consult a physician before beginning any rehabilitation program.
2. Instruct patient on proper use and all Gait Trainer 2 safety features before beginning exercise.
3. Always attach the Safety Lanyard to the patient’s clothing or wrist before allowing exercise to begin.
4. Ensure patient has stretched and warmed-up prior to starting exercise.
5. Do not allow any patient to exercise unattended on the Gait Trainer 2. Never leave the Gait Trainer 2
running unattended.
6. Periodically monitor the heart rate of patients exercising on the Gait Trainer 2.
7. Begin all exercise at a slow pace, increasing speed gradually to patient tolerance and progressing toward
exercise goals. Always inform the patient immediately prior to increasing or decreasing speed or eleva-
tion.
8. If reversing belt direction, bring the Gait Trainer 2 to a complete stop and inform patient that the belt
will begin moving in the opposite direction.
9. Immediately discontinue exercise if patient feels faint, dizzy or short of breath.
10. Never allow anyone to step onto the Gait Trainer 2 while the treadbelt is in motion. Always stop the
Gait Trainer 2 prior to allowing the patient to step up onto the treadbelt.
11. Instruct patients to use the handrails when first learning to walk on the Gait Trainer 2.
1. Tous les patients doivent voir leur médecin responsable avant d’entreprendre la séance de rééducation.
2. Expliquer au patient la bonne utilisation des systémes de sécurité du tapis avant de démarrer la séance.
3. Connector toujours la sangle de sécurité aux vêtements du patient ou poignet avant que le patient ne
commence à travailler.
4. Vérifier que la patient s’est échauffé et a fait des étirements avant de commencer l’entraînement sur le
tapis.
5. Ne pas laisser le patient seul sur le tapis pendant la séance. Ne jamais laisser le tapis tourner sans
patient et sans surveillance.
6. Surveiller de temps à autrela fréquence cardiaque du patient pendant la séance.
7. Démarrer les protocloes à une vitesse lente et augmenter progressivement la vitesse en fonction de la
tolérance du patient et progres uers les objectifs de la séance. Signaler avant de l’appliquer tonte aug-
mentation ou diminution de vitesse ou d’inclinaison.
8. Avant de changer la direction de déplacement du tapis, arrêter le tapis complétement et expliquer au
patient que le tapis va démarrer dans le sens opposé.
9. Arrêter la séance immédiatement en cas de dyspnée, d’étourdissements ou d’autres signes de malaise.
10. Ne jamais faire monter personne sur le tapis pendant que le tapis est en marche. Arrêter toujours le
tapis avant que le patient ne s’y positionne.
11. Donner la consigne au patient d’utiliser les barres horizontales lors de sa premiére séance sur le tapis.
2. CLINICAL CONSIDERATIONS FOR GENERAL USE
—2-1 — CLINICAL CONSIDERATIONS FOR GENERAL USE
Figure 3.1. Attaching the Safety Lanyard, printer cable and printer.
Included with the Gait Trainer 2 are a printer, printer stand and Safety Lanyard. These should all
be attached/installed prior to operation of the Gait Trainer 2.
CONNECTING THE PRINTER
(See Figure3.1.)
The printer cable should be connected to the printer receptacle at the back of the display with the
USB cable end. Attach the opposite end of the cable to the back of the printer.The cordshould run
down the back of the display and over the motor cover so as not to be in contact with the moving
belt. Place the printer on the printer stand. Ensurethat the printer stand is positioned next to the Gait
Trainer 2 but far enough away so as not to come in contact with the Gait Trainer 2’s moving parts.
Note: The printer receptacle is for the printer only. Do not plug anything else in this receptacle.
Nota: La prose pour imprimante est destinée à la seule imprimante. Ne brancher rien d’autre dans cette prise.
CONNECTING THE SAFETY LANYARD
(See Figure 3.1.)
A Safety Lanyard is provided. The Gait Trainer 2 will not operate unless the lanyard is attached.
Attach the Safety Lanyard at the left corner of the top cross bar supporting the Display panel. The
round end of the Safety Lanyard attaches to the unit via a Velcro® brand hook and loop fastener.
The clip end of the lanyard should be attached to the patient’s clothing or wrist in a way that does
not interfere with the patient’s exercise.
NOTE: Disconnecting the Safety Lanyard (left side of Display/Control Panel) or pressing the red Safety
Stop (atop the right side of the Support Bar) at any time will cause the treadbelt to immediately ramp down
to a full stop and reset to 0.0 mph. The Display will read <Safety Lanyard Removed> and the treadbelt will
not restart until the Safety Lanyard is once again in position and/or <Start> is pressed following use of the
Safety Stop. Display data is not lost in either case. Data accumulation will resume once the lanyard is recon-
nected and <Start> has been pressed.

—3-3 — SET-UP
The Biodex Gait Trainer 2 can be used for gait training applications, or as a rehabilitation tread-
mill. The following section describes use in the Gait Training Mode. Rehabilitation treadmill oper-
ation is described later in this manual.
THE GAIT TRAINING MODE
The Gait Training Mode is useful for the rehabilitation and retraining of gait for patients with neu-
ralgic and orthopedic gait dysfunctions. It provides both audio and visual feedback for patient
compliance. The rhythmic movement of the treadbelt along with the audio and visual biofeed-
back, provides the necessary stimulus for retraining neural pathways, thus improving the gait pat-
tern of the patient.
NOTE: It is recommended that the Biodex Unweighing System be used in conjunction with the Gait Trainer
2to provide a safe environment for the patient and clinician, and also to allow for proper patient position-
ing for weight distribution and coordination of balance.
POWER-UP
