SAFETY INFORMATION
WARNINGS & CAUTIONS
- Carefully read fitting instructions and warnings prior to use. To ensure proper performance of the brace, follow all instructions. Failure to properly position the brace and fasten each strap will compromise performance and comfort.
- This device will not prevent or reduce all injuries. Proper rehabilitation and activity modification are also essential part of a safe treatment program. Consult your licensed health care professional regarding safe and appropriate activity levels while wearing this device.

e-vive Knee Brace
The e-vive knee brace is used with e-vive knee conductive garment, refer to
e-vive NMES System User’s Manual for information related to the conductive
garment.
The following picture shows the e-vive knee brace and the main components. The
hinge can be locked out at full extension or a specific angle, or adjusted to
limit knee range of motion. 
Instructions for Applying the Knee Brace
Position the Brace:
Sit on the edge of a stable chair
With the straps undone, place the brace behind the knee
Position the hinge brace bars to the midline of the knee
Center the hinges with the knee cap
Secure the Brace:
Be careful to maintain the lateral and medial positions of the hinge bars.
Starting with brace strap A, feed strap through its associated loop and attach
so the brace is snug against the leg.
Attach remaining brace straps in order:
- Brace strap B
- Brace strap C
- Brace strap D
Verify that the brace bars are aligned along with the midline of the leg.
The brace should fit snug to the leg.
Clinician may trim excess material as needed. The Alligator strap tabs enable
easy strap trimming.
To Trim the Straps:
Remove the Alligator tab from strap ends by pulling up on the fabric adjacent
to the rubber logo tab on both sides of the strap.
Trim excess material starting from the end of the strap– take care to not cut
too short.
Replace the Alligator tab by re-attaching the fabric onto both ends of the
strap with the hook-and-loop material facing down.
Secure straps.
Using the lockout feature of the e-vive knee brace:
The e-vive knee brace can be locked out at 0° (extension) via the slide lock
to prevent knee motion.
Locking the knee brace in extension:
To lock out the brace in extension, fully extend your leg and align the slide
lock between the two white lines on the hinge. When positioned, move the slide
lock towards your foot to secure. Ensure that the slide lock is fully seated
into its mating slot on the hinge. Repeat for both knee brace hinges. Confirm
the slide lock is fully seated on each hinge.
Unlocking the knee brace:
With your leg fully extended, move the slide lock on both brace hinges towards
your thigh. Carefully, retract the slide lock to ensure it is completely
removed from the mating slot on the hinge.
Instructions for Operating the e-vive KneeBrace
The e-vive knee brace can be used to limit or lockout the flexion and
extension range of motion of the knee. Each brace has an independent hinge on
both sides of the knee joint. The hinge dial is used to adjust the extension
and flexion range of motion of its associated hinge. The extension limit can
be set to -15° (hyperextension) or from 0° to 90° in 15° increments. The
flexion limit can be set from 15° to 135° in 15° increments.
NOTE: The knee brace hinge dials on both sides should always be adjusted
to the identical settings prior to use.
Setting the e-vive knee brace extension and flexion limits:
Removing the extension limit:
Rotate the hinge dial towards the EXTENSION setting until the locking disc
pops out and releases the extension limit.
Setting the extension limit:
Rotate the hinge dial to the desired EXTENSION setting and push in the locking
disc firmly until seated.
Removing the flexion limit:
Rotate the hinge dial towards the FLEXION setting until the locking disc pops
out and releases the flexion limit.
Locking
the Hinge Dial
Once the desired EXTENSION and FLEXION Limits have been set, the hinge dial
should be rotated to the LOCK position to prevent unintentional rotation of
the hinge dial.
NOTE: To lock the hinge at any setting (in 15° increments), set the extension and flexion limits to the same number. To accomplish this, set flexion limit first, then set the extension limit. To unlock, disengage the extension first, and then the flexion limit.
3.5 Instructions for Detaching the e-vive KneeBrace
Your doctor may request to use the knee brace for a period of weeks. The knee brace may be removed from the e-vive conductive garment. To do this, detach the straps and remove from the associated loops. Then, peel the brace bars, straps, and pockets away from the sides of the conductive garment. The parts removed may be discarded or stored as desired.
