Tru-Trac® Traction Unit

This manual has been written for the operators of the Tru-Trac traction unit. It contains general instructions for operation, precautionary instructions, and maintenance recommendations. In order to obtain maximum life and efficiency from your Tru-Trac traction unit, and to assist in the proper operation of the unit, read and understand this manual thoroughly. The specifications put forth in this manual were in effect at the time of publication. However, owing to Chattanooga Group's policy of continuous improvement, changes to these specifications may be made at any time without obligation on the part of Chattanooga Group. Before administering any treatment to a patient, you should become acquainted with the operating procedures, as well as the indications, contraindications, cautions, warnings, and dangers. Consult other resources for additional information regarding the application of traction therapy.

Product Description The Tru-Trac traction unit is a simple to use digital touch screen user interface traction unit that offers static, intermittent, and cyclic traction with user definable hold, rest, and treatment times. Patient Pain Profiles are recorded before and after treatment with a Numeric Pain Scale, VAS (Visual Analog Scale), and Pain Map for each patient. Once treatment parameters are customized for a patient, clinicians can store them as either the default user protocol or as one of ten user defined protocols. The Tru-Trac traction unit contains a Patient Data Card port, providing access to store the above session parameters on Patient Data Cards.

ABOUT TRACTION THERAPY

Tru-Trac® Traction Unit Static Traction Therapy This term denotes that a steady amount of traction is applied for periods from a few minutes up to 99 minutes. The shorter duration is usually coupled with more weight. Static lumbar traction is most effective if a split table is utilized to reduce friction. It is important that it is the type that maintains constant tension. This way, any slack developed as the patient relaxes during the traction therapy is automatically taken up and the desired amount of traction is maintained. Static traction is sometimes referred to as sustained traction.

OVERVIEW OF TRACTION THERAPY Effects of Traction Therapy The Tru-Trac traction device provides a treatment in static, intermittent, and cyclic distraction forces to relieve pressures on structures that may be causing pain of skeletal or muscular origin (cervical, thoracic, lumbar, hip, wrist, shoulder). Therapeutic distraction can be applied in a variety of programmable patterns, cycles and functions.

COMMON TERMS Progressive Traction Progressive traction refers to a traction phase during the treatment when the tension gradually increases.

Intermittent Traction Therapy This form of traction alternates traction tension between tension levels - Maximum and Minimum - every few seconds throughout the timed treatment. It is also most effective if a split table is used to reduce friction when giving lumbar traction. In the progressive and regressive phases, the traction unit pulls to the calculated tension, holds for the set hold time, then drops to 50% of this tension, holds the set rest time and then repeats this step for the number of steps selected. However, once the minimum level is reached, the traction unit uses the minimum level for the rest time.

Regressive Traction Regressive traction refers to a traction phase during the treatment when the tension gradually decreases. TX (Traction) TX (Traction ) refers to the type of traction used during a treatment. There are three modes to choose from: Static, Intermittent or Cyclic Traction Mode. Steps The term “step” refers to the increment in which the traction tension is either increased or decreased during therapy.

Cyclic Traction Cyclic traction refers to progressive (gradually increasing traction tension) and regressive (gradually decreasing traction tension) phases of the traction program being repeated continuously throughout the entire course of the traction treatment.

INDICATIONS

CONTRAINDICATIONS

The Tru-Trac traction device provides traction and mobilization of skeletal structures and skeletal muscles.

Traction is contraindicated for the following: • Structural disease secondary to tumor or infection

The Tru-Trac traction device may be used to relieve peripheral radiation/ sciatica and pain associated with: • Protruding discs • Bulging discs • Herniated discs • Degenerative disc disease • Posterior facet syndrome • Acute facet problems • Radicular pain • Prolapsed discs

• Patients with vascular compromise • Any condition for which movement is contraindicated

• Spinal root impingement • Hypomobility • Degenerative joint disease • Facet syndrome • Compressions fracture • Joint pain • Discogenic pain

• Patients with acute strains, sprains, and inflammation which would be aggravated by traction therapy • Patients with joint instability of the spine • Pregnancy • Osteoporosis • Hiatus hernia • Claustrophobia

The Tru-Trac traction device achieves these effects through decompression of intervertebral discs, that is, unloading due to distraction and positioning.
