MMT OF CORE MUSCLES
Presented By: SYEDA TAHANI.
INTRODUCTIO
N
ļ‚ MMT is the procedure used to evaluate the function
and strength of an individual or group of muscles.
ļ‚ It is based on the efficiency of the performance of
the movement in relation to force of gravity or
manual resistance.
ļ‚ It helps to determine the extend and degree of
muscular weakness.
GRADES OF MMT
ļ‚ Grade 0 : No contraction or no movement.
ļ‚ Grade 1 : Flickering of contraction.
ļ‚ Grade 2 : Full ROM eliminating gravity.
ļ‚ Grade 3 : Full ROM against gravity.
ļ‚ Grade 4 : Full ROM against gravity with minimum
resistance.
ļ‚ Grade 5 : Full ROM against gravity with maximum
resistance.
TRUNK FLEXION
Muscles :
The muscles involved include:
•PRIME MOVERS:
•Rectus abdominis.
•ACESSORY MUSCLES:
•Internal abdominal oblique.
•External abdominal oblique.
PATIENT POSITION :
•Grade 5 (Normal): Supine with fingertips
lightly touching the back of the head
•For grade 4- Supine with arms crossed
over chest
•For grade 3- Supine with arms at side.
•For grade 0 to 2- Supine with arms at
sides and knees flexed.
THERAPIST POSITION :
•Grade 3 to 5- Standing at side of table at level
of patient's chest to be able to see whether
scapulae clear table during test
•grade 0 to 2- Standing at side of table with the
hand used for palpation is placed at the
midline of the thorax over the linea alba, and
the four fingers of both hands are used to
palpate the rectus abdominis
MOVEMENT :
•For grade 3 to 5- Patient flexes trunk
through complete range of motion. A
curl-up is emphasized and trunk is curled
until scapulae clear table
•For grade 2- Ask the patient to lift the head
from the table. If the scapulae do not clear
the table, the Grade is 2.
•For grade 0 and 1- therapist uses assisted
forward lean technique or coughing
technique in same position, while palpating
rectus abdominis.
TRUNK EXTENSION
ļ‚ The involved muscles are:
ļ‚  PRIME MOVERS:
ļ‚  Erector spinae, Iliocostalis thoracis,
Longissimus thoracis, Spinalis
thoracis, Iliocostalis lumborum,
Quadratus lumborum.
ļ‚  ACESSORY MUSCLES:
ļ‚  Semi spinalis, Multi fundus,
Rotators.
When testing the thoracic and lumbar
spine strength a few differences are
noted:
•The Grades 5 and 4 tests for spine
extension are different for the lumbar
and thoracic spines.
• Beginning at Grade 3, the tests for
both spinal levels are combined.
•Range of Motion are also different:
Thoracic spine: 0° to 10°: Lumbar spine:
LUMBAR SPINE
ļ‚  Position of Patient: Prone with hands clasped
behind head.
ļ‚  Position of Therapist: Standing so as to stabilize
the lower extremities just above the ankles if the
patient has Grade 5 hip extensor strength. The
weight of the head and arms essentially
substitutes for manual resistance by therapist.
ļ‚  Test: Patient extends the lumbar spine until the
entire trunk is raised from the table (clears
umbilicus).
ļ‚  Instructions to Patient: ā€œRaise your head,
shoulders, and chest off the table. Come up as
high as you can.ā€
Lumbar spine extension
THORACIC SPINE
ļ‚  Position of Therapist: Standing so as to stabilize the lower limbs at the
ankle.
ļ‚  Test: Patient extends thoracic spine to the horizontal.
ļ‚  Instructions to Patient: ā€œRaise your head, shoulders, and chest to table
level.ā€
• Grade 5 (Normal): Patient is able to raise the upper trunk quickly from
its forward flexed position to the horizontal (or beyond) with ease and
no sign of exertion
• Grade 4 (Good): Patient is able to raise the trunk to the horizontal level
but does it somewhat laboriously.
• Grade 3 (Fair): Patient completes the range of motion.
• Grade 2, Grade 1, and Grade 0: These tests are identical to the Grade 3
test except that the therapist must palpate the lumbar and thoracic
spine extensor muscle masses adjacent to both sides of the spine. The
individual muscles cannot be isolated.[3
Thoracic
extension .
TRUNK ROTATORS
ļ‚  PRIME MOVERS:
ļ‚  External abdominal oblique.
ļ‚  Internal abdominal oblique.
ļ‚  ACESSORY MUSCLES:
ļ‚  Latissimus dorsi.
ļ‚  Multifidus.
ļ‚  Semispinalis.
ļ‚  Rectus abdominis(combines trunk rotation
and flexion.) External abdominal
oblique
Internal abdominal oblique
PATIENT POSITION
ļ‚ Grade 5 : Supine with fingertips to the side of the
head.
ļ‚ Grade 4 : Supine with arms crossed over the
chest.
ļ‚ Grade 3 : Supine with arms placed above the
plane of the body.
ļ‚ Grade 2 : Sitting arms placed at the side.
ļ‚ Grade 0 and 1: supine with knees bent and arms
placed at the side of the body.
THERAPIST POSITION
ļ‚ Grade 3 to 5 : Standing at the side of the table
at the level of patients feet and stabilizing just
above the ankle and at the knee joint.
ļ‚ Grade 2: Standing at the side of the table and
stabilizing the pelvis.
ļ‚ Grade 0 and 1 : Standing at the level of
patients waist. Therapist palpates the muscles
with one hand and the other supports the
head.
MOVEMENT
ļ‚ Grade 2 to 5 : Patient rotates and
flexes thorax to one side and
repeat to opposite side.
ļ‚ Grade 0 and 1 : Palpate the
muscle contraction during the
attempt to rotate.
