• They are constructed out of
strong fabrics or elastic
materials with a variety of
RIGID SPINAL ORTHOTICS
• They are used when greater
control of motion or
posture is required.
• They are fabricated from
thermoplastics or light
• There are wide varieties
with a broad selection of
pads and coverings.
THERAPUETIC BENEFITS OF
• TO INCREASE INTRA ABDOMINAL PRESSURE
-They create cylinder effect, exert pressure on
the abdomen, and raise intra-cavitary pressure
and reduce the intra-discal pressure especially
during forward bending.
• MUSLE RELAXATION
-Support the vertebral column and relaxing the
abdominal and erector spinae muscles
-Decreasing the need for contractile support of
the vertebral column may relax the muscles and
reduce existing pain.
• RESTRICTION OF MOTION
-The primary method employed for motion
control is the three point pressure system.
A rigid system is used when cervical, thoracic
and lumbosacral motions are sought to be
limited to the greatest possible degree.
-Reduction of motion will reduce pain and spinal
instability and offer constant proprioceptive
feedback, reinforcing positive behaviors.
• POSTURAL REALIGNMENT
-↑intra abdominal pressure, relaxation in
muscle spasm, and restriction of movement can
assist in facilitation of improved posture and
reduce compensatory posture related pain.
• SACROILIAC CORSET
-Made from a combination of fabrics, elastic, laces and
velcro offering multiple adjustments
-Encircle the waist from the iliac crest to the greater
trochanter and extending anteriory to the symphysis
-Provide postural stability and reinforcement.
• LUMBOSACRAL CORSET
-Made from heavy fabrics with laces and hooks.
-It is designed to limit motion, maintain three point
pressure system and to reduce pain
• DORSO LUMBO
-The same construction
and function of
lumbosacral corset except
it includes a shoulder
strap to restrict spinal
motion to the thoracic
region as well as to the
• TAYLOR SPINAL BRACE
-a pelvic band connects with two posterior uprights
terminating at the midscapular level of the thoracic
region, with an anterior abdominal closure and axillary
straps. Two three point pressure systems are coupled
together to limit both flexion and extension of the
lumber and thoracic spine.
-it increases the movement at the lumbo sacral
• FISHER SPINAL BRACE
- A pelvic band to which two pelvic hoops,& two
posterior upright rods connected. Another horizontal
rod at the level of infra scapular area connects the
long rods. It also has long lateral rods
- It does not designed for axillary weight
- Limits forwards flexion & extension of the lower
thoracic and upper lumbar spine. Lateral flexion
limited more than taylors brace.
ANTERIOR HYPEREXTENSION BRACE
-a three-point pressure system is created with two
pads, one across the sternum and one at the symphysis
pubis, providing the counterforce with a single pad
posteriorly to promote hyper extension and restricting
CORRECTIVE SPINAL ORTHOSES

- Used in pts with
structural scoliosis who is

• BOSTON BRACE
- The pelvic corset opens
- It is designed for
treatment of dorso-
lumbar scoliosis in

ORTHOSES FOR C-SPINE
• SOFT COLLAR
-made from soft foam, the collar
provides mechanical restraint for
cervical flexion and extension
and, to a lesser degree, lateral
flexion and rotation.
- Although the soft collar provides
minimal restriction of
movement, it is a good
transitional appliance from more
rigid orthoses, and acts as a
proprioceptive reminder to the
wearer to limit head and neck
• HARD COLLARS
-Constructed from semirigid and rigid plastics.
Hard collars provide more rigid stabilization of the
cervical spine and typically offer some type of chin
and occipital support, with the inferior collar
extending to the sternal notch and to the T3
spinous process posteriorly.
- Generally, hard collars such as the Philadelphia
collar limit motion much more than soft collars, but
on average still permit 40 to 50 percent of normal
• SOMI BRACE
-it does not have the back plate, thus allows the pt to
lie comfortably on bed.
-it has a chest plate and two shoulder extensions.
- three adjustable uprights, two for the occiput and
one for the mandibular support.
- More effective in controlling of flexion at upper c-
spine. But not so effective for extension an lateral
rotation of cervical spine.
• FOUR POST CERVICAL COLLAR
- It consists of two padded plastic plates one anteriorly
over chest one posteriorly between interscapular
- Also contain one chin cup and one occipital cup.the
ant&post cups are connected by plates with two
- Limts flexion ,extension& lateral rotation of lower
and middle parts of c-spine.
• HALO BODY
-if a lesion present in the
upper most part of c-spine
along with c-spine the
forehead also include in
