Muscle Energy Techniques to Increase Craniocervical Mobility
Muscle energy (ME) uses the application of sub maximum,
isometric contractions of muscles whose line of pull can cause the desired
accessory motion of a joint:
ME techniques are designed to improve joint
mobility. The patient holds the gentle muscle contraction
against the therapist's graded resistance for 3 to 5 seconds and then relaxes.
This process is repeated for three to five repetitions. When
performed correctly, ME techniques are extremely safe and are indicated for
most joint restrictions resulting from musculoskeletal disorders.
PRECAUTION:
Great care should be used when applying the
following techniques so as not to occlude the vertebral artery The therapist
should test the integrity of the vertebral artery prior to performing the
following ME techniques.

Do not perform ME techniques if the patient reports an
altered sensation in either upper extremity or a feeling of dizziness or
light-headedness during the set-up of these techniques.
Patient position: Supine, with hands placed comfortably at
the side.
Therapist position, hand placement, and patient effort:
Stand at the head of the treatment table. Support the occiput with one hand and
place the other hand across the forehead.
Ask the patient to look upward gently
as if nodding the head back wards and apply resistance against the patient's
occiput, creating a gentle isometric contraction in the suboccipital muscles.
When the patient relaxes, take up the slack by passively nodding the head
through any new range.
Alternate technique:
Sit on a stool at the head of patient
with your forearms resting on the treatment table. One hand stabilizes the C2
vertebra by grasping the transverse processes between the proximal portions of
the thumb and index finger;
the other hand supports the occiput. Passively nod
the patient's head with the hand under the occiput to take up the slack of the
suboccipital muscles; then
ask the patient to roll the eyes up ward. This
causes a gentle isometric contraction of the subococcipital muscles. The
patient keeps looking upwards for 3 to 5 seconds and then relaxes.
After the
patient relaxes, take up the slack by passively nodding the head through any
new range,
Repeat this procedure three to five times or until the
desired outcome is achieved. Only motion between the occiput and C2 should
occur.
The contraction is gentle in order not to cause overflow into the
multi-segmental erector spinae and upper trapezius muscles. This technique uses
a gentle hold-relax, of the rectus capitis posterior minor muscle.
