The Causes: Lower cross syndrome develops by the shortening of spinal muscles crossed with the growing shortening of hip flexors, weak buttocks, and abdominal muscles (muscles on the front).

Which muscles are typically overactive in association with lower crossed syndrome?
Lower Crossed Syndrome
- Overactive lumbar erectors.
- Overactive hip flexors (iliopsoas and rectus femoris)
- Underactive glutes (gluteus maximus, gluteus medius, gluteus minimus)
- Underactive abdominals.
What muscles are lengthened in anterior pelvic tilt?
Anterior pelvic tilt is caused by the shortening of the hip flexors, and the lengthening of the hip extensors. This leads to an increased curvature of the lower spine, and of the upper back. The hip flexors are the muscles that attach the thigh bone to the pelvis and lower back.
What is the difference between upper and lower cross syndrome?
Upper cross syndrome refers to the upper part of the body, namely the neck/upper back/chest/shoulder areas. Lower cross syndrome refers to the lower part of the body surrounding the pelvis/lower back/abdominal/upper thigh areas.
Which muscles are typically underactive in association with upper crossed syndrome Nasm?
Meanings of ‘Crossed’ and ‘Countercrossed’ The other side of the X now depicts the underactive muscles, with the deep cervical flexors down toward the mid/lower trapezius, rhomboids and serratus anterior.
What are common underactive lengthened muscles in the lower body?
Conversely, underactive, lengthened, and weak muscles include (but are not limited to) the following:
- gluteus maximus.
- gluteus medius.
- transversus abdominus.
- internal oblique.
- anterior tibialis.
- posterior tibialis.
Which muscles are typically underactive in association with pes planus distortion syndrome?
Functionally weakened or inhibited areas include the posterior tibialis, anterior tibialis, gluteus medius and gluteus maximus.
What muscles work during posterior pelvic tilt?
The motion of a posterior pelvic tilt is produced by a force-couple created by the abdominal muscles and the hip extensors (Fig. 9.26). The interaction of these two groups of muscles provides enhanced control of the hip and pelvis in a wide variety of postures.
Which muscles are tight in posterior pelvic tilt?
The typical muscle imbalance scenario that causes posterior pelvic tilt involves tight hamstrings, glutes and lower abdominal muscles coupled with weak quadriceps, psoas and lower back muscles. Tight muscles exert a pull on body structures that is not counterbalanced by the pull of weak muscles.
Does anterior pelvic tilt make you look fatter?
When you have a weak posture, this can cause an anterior pelvic tilt, where your pelvis tilts forward – and when this happens, your lower back arch becomes pronounced, your bum sticks out and your stomach protrudes, which creates the illusion of a larger stomach.
What muscles are weak with lower cross syndrome?
The lower crossed syndrome involves weakness of the trunk muscles: rectus abdominis, obliques internus abdominis, obliques externus abdominis and transversus abdominis, along with the weakness of the gluteal muscles: gluteus maximus, gluteus medius and gluteus minimus.
What muscles are weak in upper crossed syndrome?
In the condition known as UCS, mid-back muscles (serratus and lower trapezius) become very weak. As a result, the pectoral and neck muscles tighten. This causes pain throughout the upper body, including shoulder pain and neck pain, as well as a reduced range of motion.
What are phasic muscles?
Phasic muscles contain mostly fast-twitch muscle fibres, and are therefore more suited to movement. They are prone to inhibition. Postural muscles tend to shorten in response to over-use, under-use or trauma, whereas phasic muscles tend to lengthen and weaken in response to these types of stimuli.
Which muscles are typically underactive with knee valgus during the single leg squat?
The most common compensation observed in a single leg squat is seeing the knee move inward with torso rotation. Your knee caving inward (valgus) can be a sign of overactive adductor complex (lack of groin flexibility) and underactive gluteus medius.
Which muscles are typically underactive with knee valgus during the overhead squat?
A common improper movement pattern observed during a squat is knee valgus (knees caving inward). This is typically the result of strong hip adductor muscles (located on the inner thigh) overpowering the weak hip abductors (gluteus minimus and gluteus medius).
Which muscles are typically underactive when the feet turn out?
When your foot (or feet) turn out, this means that you probably have some overactive calf muscles (soleus and lateral gastrocnemius) and bicep femoris (part of your quadricep) as well as underactive calf muscles (medial gastrocnemius), hamstrings and adductors.
