LATERAL SUBSYSTEM (LSS)


Human movement consists of a number of subsystems to create performances. If one subsystem is not working optimally the rest can not function efficiently.

🔺The LATERAL SUBSYSTEM is one of the four subsystems that stabilise the pelvis. …

🔺This system is made up of:

– Gluteus medius (your butt)

– Tensor fascia latae (side butt)

– Hip adductors (groin) (adductor brevis, adductor longus, adductor magnus, pectenius and gracilis) – Contralateral (opposite side) Quadratus Lumborum (lower back)

🔺it’s ROLE is frontal plane stability. In other words, the subsystem is a major stabiliser of the pelvis and spine in single leg movements such as walking 🚶🏼, running 🏃🏼‍♀️,lunges, step ups, etc. In more words, that means EVERYONE is ALWAYS using this subsystem 👥👥.

🔺When the weight is transferred on one side (let’s say the right side), the right gluteus medius (butt) works with the QL (lower back) on the opposite side to provide stability.

🔺During single leg stance, the gluteus medius (butt) is responsible for keeping the hips level. 

A weak or inhibited right glute means a drop ⬇️ in the left hip. 

Tightness, spasms and compression at the lower back, increased pronation of the knee, hip or feet are all common dysfunctions due to compensation in this system 😫 

These dysfunctions can be seen in dynamic (running, walking) or static postures. …

🔺Pain 💉often presents itself through knee pain, tendonitis, chronic tightness in the ITB, hip pain, plantar fasciitis, pulled groin and adductor injuries, lower back pain, ankle injury and sacroiliac joint pain. …
