This product has 2 adjustment mechanisms. One is adjustment mechanism of planter flexion braking force and the other one is adjustment mechanism of initial angle. You can set proper setting of orthosis for each user by adjusting these 2 mechanisms.
■ Adjustment of planter flexion braking force
You can change planter flexion braking force by rotating adjustment shaft in hydraulic unit and adjust open and close volume
of hydraulic valve.
of hydraulic valve.
1.Loosen set screw for adjustment shaft with hexagon wrench M1.6 in accessory and make adjustment shaft can rotate.
2. Rotate adjustment shaft with flathead screwdriver to set proper planter flexion braking force.
※ You can set planter flexion braking force voluntarily from weak (soft) to strong (semi fixed).
※ You can set planter flexion braking force voluntarily from weak (soft) to strong (semi fixed).
Markings from 1 to 4 are in the upper part of hydraulic unit.
You can adjust the braking force by using those markings for indication. (You can set detailed setting like 2.3 or 2.45).
You don’t need to count the number of rotations like spindle system because this adjustment shaft can change open and close volume of hydraulic valve in single rotation. The planter flexion braking force should be deferent from each user’s weight, body condition and gait or rehabilitation procedure. You should set proper planter flexion braking force from medical doctor’s prescription or observation of user’s gait in rehabilitation program.

3.Tighten set screw for adjustment shaft and fix adjustment shaft
■Adjustment of initial flexion
You can set initial flexion angle in 0 and 5 degree by replacing rod cap in hydraulic unit.
You can also set initial flexion angle toward planter flexion by carving cam.
You can also set initial flexion angle toward planter flexion by carving cam.
1.Loosen set screw for adjustment shaft with hexagon wrench M1.6 in accessory and make adjustment shaft can rotate.
2. Replace rod cap to the one with proper height
※You should adjust the initial flexion angle after checking toe clearance during swing phase while walking with shoes.

3.Tighten set screw for rod cap in reverse order of 1 and fix rod cap
4.Confirm initial flexion in standing position with shoes. In case that you observe strong pushing to cam, you should carve cam and set proper initial flexion angle.
