Body Language – From Commons Signs to Spotting Lies

Here is a fun exercise to help you practice your body language reading skills. Turn on a movie or tv show, but turn the sound off. It is amazing when there are no words to distract us, how much better we can read the body language and understand the feelings and emotions of the communication.

Physical Activity Linked to Healthier and Longer Life, but Highly Physically Active Workers Die Early

When working, we place a demand on the body and the body responds by adapting to meet those demands. However, every tissue, has a limit to the mechanical stress that it can accept during physical activity without injury. It would seem likely that the demands of some professions are too great for the human body.

Differences in Knee and Hip Adduction in Runners with Iliotibial Band Syndrome

This study seems to show a relationship between iliotibial band (ITB) syndrome and knee adduction (genu varum) and the activation of the TFL. A relationship can be two incidents that occur together, termed a “coincidence.” Or there can be a causal relationship between them; i.e., one causes the other to occur.

Genu Knee Valgus

Decreased Ankle Dorsiflexion is Associated with Dynamic Knee Valgus

A proposed biomechanical explanation is that restricted ankle joint dorsiflexion directly results in overpronation of the foot, which causes internal rotation of the lower extremity, which strains the external/abductor musculature, which can then no longer prevent femoral adduction; hence genu valgus.

Tight hip abductor and/or adductor musculature can change the frontal plane posture of the pelvis, resulting in a scoliosis. Permission Joseph E. Muscolino. Kinesiology - The Skeletal System and Muscle Function, 3ed (Elsevier, 2017)

How Can Tight Muscles of the Hip Joint Cause a Scoliosis?

So, if hip abductor group on one side is tighter at baseline tone than the hip adductor group on that side, the pelvis will be pulled into depression on that side, resulting in a lumbar scoliosis that is convex on that side. Similarly, tight opposite-side hip adductor musculature can cause the same scoliotic curve.

Does Carrying a Backpack Cause Back Pain in Adolescents?

And perhaps the biggest problem I have with this study about backpacks and adolescent back pain is that an overuse syndrome usually does NOT cause pain in the early stages. When the body is physically stressed by something like carrying a backpack, it often requires many years before the overuse results in pain.
