Each innominate bone (ilium) joins the femur (thigh bone) to form the hip joint; thus the sacroiliac joint moves with walking and movement of the torso. [9] In this joint, hyaline cartilage on the sacral side moves against fibrocartilage on the iliac side. The sacroiliac joint contains numerous ridges and depressions that function in stability.
Rigid spine syndrome, also known as congenital muscular dystrophy with rigidity of the spine (CMARS), is a rare and often debilitating neuromuscular disorder. It is characterized by progressive muscle stiffness and rigidity, particularly in the spine, which can severely limit mobility and impact quality of life. This condition is typically ...
The bones provide stability to the body. Muscles keep bones in place and also play a role in the movement of bones. To allow motion, different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly onto each other. Muscles contract to move the bone attached at the joint.
The leg muscles acting on the foot are called the extrinsic foot muscles whilst the foot muscles located in the foot are called intrinsic. [28] Dorsiflexion (extension) and plantar flexion occur around the transverse axis running through the ankle joint from the tip of the medial malleolus to the tip of the lateral malleolus.
In these appointments, my physical therapist and I discovered that the most intense pain was coming from my right sacroiliac (SI) joint, which links the pelvis and lower spine. We worked on ...
Pressing on an affected muscle can often refer pain. Clusters of trigger points are not uncommon in some of the larger muscles, such as the gluteus group (gluteus maximus, gluteus medius, and gluteus minimus). Often there is a heat differential in the local area of a trigger point. [citation needed]
Eventually, rigidified muscles reduce the affected person's range of motion, slow their voluntary movements, and may cause them to have abnormal posture, particularly lumbar hyperlordosis (a distinctive curve in the lower back). [6] Rigid trunk muscles can also prevent the chest and abdomen from expanding, causing shortness of breath and early ...
Muscle memory helps you get back into shape faster after a break, makes complex movements feel more intuitive, and allows you to transition between similar activities easier (think: from tennis to ...
