7 Fitting Advice

The correct alignment (A-P position), range of motion (distribution of plantar to dorsi flexion) and
adjustment of the hydraulic settings are critical in achieving a smooth roll over and correct slope
adaptation (see 6.3).
The springs for the echelon foot will be supplied assembled with heel and toe springs of the
same category. If after following the instructions below you still have problems with the function
please contact the sales team in your area for advice.
Any of the following:
• Incorrect spring selection
• Incorrect A-P shift alignment
• Incorrect distribution of plantar and dorsi flexion range will have a negative effect on
function and stability
1. Sinking at heel strike
Difficulty in achieving a smooth
progression to mid stance
User feels they are walking up hill
or forefoot feels excessively long
2.
Progression from heel strike to mid
stance is too rapid
Difficulty in controlling the energy
return from the foot at the heel
strike (reduced knee stability)
User feels heel is too hard, fore foot
is too short
3. Heel contact and progression feel
OK but:
Forefoot feels too soft
Forefoot feels too short
User feels they are walking down
hill, possibly with reduced knee
stability
Lack of energy return
Symptoms:
1. Increase plantar flexion resistance
2. Check A-P shift alignment; ensure foot is not too
anteriorly positioned
3. Check distribution of plantar and dorsiflexion
movement; ensure that the plantarflexion range
is not excessive
4. Check spring category is not too soft,
if so fit a higher rate spring
1. Reduce plantarflexion resistance
2. Check A-P shift alignment; ensure foot is not too
posteriorly positioned
3. Check distribution of plantar and dorsiflexion
movement; ensure that there is adequate
plantarflexion range
4. Check the spring category is not too high for the
weight and activity of the patient, if so fit lower
rate spring
1. Increase dorsiflexion resistance
2. Check A-P shift alignment;
ensure foot is not too posteriorly positioned
3. Check distribution of plantar and dorsiflexion
movement; ensure that there is not excessive
dorsiflexion range
4. Check the spring category is not too soft for the
weight and activity of the patient, if so fit higher
rate spring
