6Training tips
The device must be adjusted to the ergonomic conditions of the user before the first training session.
The adjustment of the training device for the user is the responsibility of the qualified personnel.
•To avoid injuries and to make the training more effective, a general and special warm-up
program should be completed. This prepares the circulation and musculature for the loads.
•Select a safe and firm sitting position, with the pelvis and spine close to the seat. The back,
especially the lumbar spine, must be stabilised as best as possible during the exercise. If
available, the backrest is used to stabilise the spine.
•The equipment allows for a double-legged or single-legged or double-armed or single-armed
workout.
•The correct positioning of the patient in the starting position contributes greatly to the quality,
effectiveness and safety of the exercise performance. The device axes and pivot points must be
adjusted as precisely as possible to the movement axes of the joints to be exercised in order to
avoid the occurrence of compression and shear forces.
•Perform the movement slowly and in a controlled manner.
•The intensity of the load should be chosen lightly at the beginning of the training. Increase the
load gradually to avoid overload and discomfort.
•The equipment allows for a double-legged or single-legged or double-armed or single-armed
workout.
•If mobility is restricted or pain occurs, immediately reduce the load and/or the extent of
movement.
•Training and therapy only take place in the pain-free area.
CAUTION
Improper or excessive training can lead to health problems.
CAUTION
Pressurized breathing and the associated increase in intrathoracic pressure
can lead to damage to the vascular system in people at risk. Perform
movement slowly and in a controlled manner.
WARNING
If you experience symptoms such as rapid heartbeat, dizziness, shortness of
breath, nausea or chest pain, profuse sweating or headache, stop exercising
immediately.

17
•During fast-impact exercises, the weight can be moved explosively. Controlled movement must
be ensured, especially with this training method, so that incorrect loads and injuries are avoided.
Usually concentric and eccentric ways of working the muscles are combined.
•Different training methods are used. If training is done according to the repetition method,
several series of exercises are performed with appropriate breaks.
•The load intensity is based on the load capacity of the individual indications, the rehabilitation
phase and the treatment goal. For example, in order to adapt and accustom the injured structure
(connective tissue, cartilage, tendons, ligaments and joint capsule), the focus can be on weight
bearing with low training intensity, before the training of special strength skills, such as strength
endurance or maximum strength, begins with increasing intensity.
•In order to be able to reproduce the training positions made by a therapist/trainer at a later,
possibly independent training, all adjustment devices are provided with scales and numbered
alphabetically (A, B, C, ...).
•With all devices there is the possibility to stabilize the patient*/customer* optimally during the
training.
WARNING
Risk of injury. Keep a safety distance of at least 60 centimetres from moving parts.

7Device descriptions
7.1 compass®MTT International Back Trainer
Intended use
Compass ®MTT International Back Trainer is designed for muscular stabilization of the back muscles. In
the lateral position of the user, the compass®MTT International Back Trainer is designed for muscular
stabilization of the lateral flexors.
Application
Depending on the training condition of the patient, different starting positions can be set via the manual
adjustment. This makes the back trainer suitable for beginners as well as for people who are already
trained. The degree of difficulty of the exercise is increased when the training position is increasingly
changed to horizontal and the patient works more against gravity. A scale is provided to help control
the training position. This means that the same starting position can be adopted again for the next
workout. The height of the support pad on the abdomen can be adjusted to the patient's height - this
ensures that the axis of rotation is optimally set up according to the training goal. Optional: For training
the lateral flexors, the patient positions himself laterally in the device. An additional pelvic stabilization
pad prevents twisting and overstretching of the lumbar spine during exercise. As with training the back
extensors, the degree of difficulty can be changed by altering the starting angle.

7.2 compass®MTT Crunch Bench
Intended use
Compass®MTT Crunch Bench is designed for muscular stabilization of the ventral
musculature/abdominal musculature.
Application
It is trained in the supine position, the legs are fixed in a 90° position on the lower leg pad. The leg
length can be individually adjusted by adjusting the lower leg pad by means of locking bolts on the back
of the device. A grab handle helps when getting on and off the machine. The back padding can be
adjusted according to the patient's training condition. To adjust, pull out the locking bolt under the pad
and bring the back pad into the desired position. An increasingly vertical adjustment facilitates the
exercise; if the backrest is lowered, the demand on the muscles involved increases. Due to the convex
shape of the backrest pad, the abdominal muscles are trained from a pre-stretching position. The lower
back should always remain in contact with the pad during the exercise. The pelvis can be fixed to the
device with the help of the safety belt attached to the side of the device. The arm position is independent
of the patient's performance status. In order to optimally stabilize the shoulder girdle during training,
the arms are held turned outwards next to the torso. If the patient is in a very good training condition,
the arms can also be held next to or behind the head. Tensile stress on the cervical spine must be avoided
at all costs. If training is to take place only in the restricted range of motion, the back pad is placed in an
upright position in order to reduce the angle between the trunk and the legs, depending on the patient's
training condition.
