Hello, my name is doctor elliot smithson and I’m a physical therapist in the esports
industry. I have worked with many players across different titles and today we will be
discussing some of the benefits of instability training for core strength.

Pathophysiology of lumbar spine conditions is covered extensively in the medical
course but as a brief recap we will provide details here of lower crossed
syndrome.
Lower crossed syndrome (LCS) is a postural condition that primarily affects the
lower back and pelvis. It is characterized by muscle imbalances and
dysfunction in the muscles surrounding the hip and lumbar spine. While LCS is
not exclusive to gamers, spending prolonged periods in a seated position,
such as during gaming sessions, can contribute to the development of this
syndrome.
Gamers, like individuals who spend long hours working at a desk, can be at risk of
developing lower crossed syndrome due to several factors:
1. Sedentary Lifestyle: Gamers often spend extended periods sitting in front of a
computer or console, which can lead to weakened muscles and poor posture
over time.
2. Muscle Imbalances: Lower crossed syndrome involves imbalances between
tight and weak muscles. The tight muscles typically include the hip flexors
(front of the hip) and the lumbar erector spinae muscles (lower back). The
weak muscles typically involve the gluteal muscles (buttocks) and the
abdominal muscles.
