8. WHAT IS UPPER &
LOWER CROSSED
SYNDROME
ORIGINALLY IDENTIFIED BY THE
ESTEEMED CZECH PHYSIOTHERAPIST
VLADIMIR JANDA, THESE
SYNDROMES ARE CHARACTERISED
BY ALTERNATING PATTERNS OF
MUSCLE INHIBITION (WEAKNESS)
AND FACILITATION (TIGHTNESS).

9. UPPER CROSSED
SYNDROME
IN UPPER CROSSED SYNDROME, THERE'S
A DISTINCT PATTERN OF MUSCLE
IMBALANCES: THE DEEP NECK FLEXORS
AND LOWER TRAPEZIUS BECOME WEAK,
WHILE THE UPPER TRAPEZIUS, LEVATOR
SCAPULAE, AND PECTORALS BECOME
TIGHT.
THIS IMBALANCE OFTEN LEADS TO
POSTURAL DISTORTIONS SUCH AS
FORWARD HEAD POSTURE,
GENERALIZED NECK AND SHOULDER
TENSION, AND AN INCREASED RISK OF
SYMPTOMS SUCH AS TENSION-TYPE
HEADACHES.

10. LOWER CROSSED
SYNDROME
LOWER CROSSED SYNDROME IS
CHARACTERISED BY WEAKNESS IN THE
DEEP ABDOMINAL AND GLUTEAL
MUSCLES, COUPLED WITH TIGHTNESS IN
THE HIP FLEXORS (ILIOPSOAS) AND LOWER
BACK EXTENSORS (ERECTOR SPINAE).
THIS MUSCLE IMBALANCE OFTEN LEADS
TO POSTURAL DISTORTIONS SUCH AS AN
EXAGGERATED LUMBAR CURVE
(HYPERLORDOSIS), ANTERIOR PELVIC TILT,
AND PROTRUDING ABDOMEN.
INDIVIDUALS WITH THIS CONDITION MAY
EXPERIENCE LOWER BACK PAIN,
STIFFNESS, AND AN INCREASED RISK OF
HIP, KNEE, AND ANKLE ISSUES.

11. TARGETED STRENGTHENING EXERCISES
FOR WEAKENED MUSCLE GROUPS,
COMBINED WITH STRETCHING
ROUTINES AND, WHEN APPROPRIATE,
REMEDIAL OR DEEP TISSUE MASSAGE
FOR TIGHT MUSCLES, CAN
SIGNIFICANTLY ALLEVIATE DISCOMFORT
AND RESTORE FUNCTIONAL BALANCE.
