Elasticords
Located within the carriage, under the head-end are eight lanyards. Once attached they engage
the Elasticord for resistance.
Elasticord Maintenance ​ - Always detach the Elasticords when machine is not in use. This
prevents premature stretching of the Elasticords and greatly extends their life.
Attaching the Elasticords​ - To increase resistance attach Elasticords one by one to the slotted
plate at the head end of the carriage.
Detaching the Elasticords​ - To decrease resistance, detach Elasticords and gently let them
retract into the carriage.
Elasticord Resistance - ​ E ach Elasticord provides 6-25 lbs of starting resistance depending on
cord type. Resistance increases as Elasticords stretch. As skill and strength improve, more
Elasticords may be added. When all Elasticords are attached they will provide up to 300 lbs of
resistance at full extension (depending on machine).
Standard Spring Scale Force Monitoring - ​ A bathroom spring scale adjusted to zero while
placed vertically on the kickplate under the patient's foot is helpful in verifying kickplate forces
generated by the Elasticords.
