Precision Targeted Movement - PTM Method

The scapula serves as a mechanical interface between the upper limb and the axial skeleton. Its orientation is governed by the interaction of cervical alignment, thoracic curvature, rib cage configuration, trunk control, and pelvic positioning.

Human biomechanics and structure reflect a complex interaction of physics, biology, neurology, and adaptation. Therefore, applying generic, one-size-fits-all training methodologies to multifactorial human systems may be overly reductionist.

WRIST
Acting as a hinge, the wrist articulates with the forearm and the bones of the hand. Together, the 27 bones in the wrist and hand allow the precise finger movements needed to perform many necessary tasks, such as typing, writing, and eating. Distally, the radius and ulna make the distal radioulnar joint, which interacts with the carpal bones. The carpus, or wrist, is composed of eight small bones arranged in two rows. The proximal row contains the scaphoid, lunate, triquetrum, and pisiform. This row interacts with the ulna and radius. The distal row contains the trapezium, trapezoid, capitate, and hamate. This row interacts with the five metacarpal bones of the hand (Moore et al., 2013).

The pelvic girdle (hip girdle) is formed by a single bone, the hip bone or coxal bone (coxal = “hip”), which serves as the attachment point for each lower limb. Each hip bone, in turn, is firmly joined to the axial skeleton via its attachment to the sacrum of the vertebral column. The right and left hip bones also converge anteriorly to attach to each other. The bony pelvis is the entire structure formed by the two hip bones, the sacrum, and, attached inferiorly to the sacrum, the coccyx.

Trong thai kỳ, bụng lớn dần làm trọng tâm cơ thể dịch ra trước, thường làm tăng độ ưỡn cột sống thắt lưng lên đến 41%. Đồng thời, hormone như relaxin làm dây chằng lỏng hơn, còn cơ bụng bị kéo giãn làm giảm ổn định vùng core, từ đó tăng áp lực lên cột sống và góp phần gây đau lưng dưới.
___________
During pregnancy, the growing abdomen shifts the center of gravity forward, often increasing lumbar lordosis by up to 41%. Hormones like relaxin loosen ligaments, while stretched abdominal muscles reduce core stability, increasing strain on the spine and contributing to low back pain.

Joint hypermobility is not inherently pathological. It is a physical trait that may offer advantages, create challenges, or remain irrelevant depending on the individual and the demands placed upon the body. Effective management depends on accurate assessment, appropriate loading, and recognition that not all joints require the same strategy.

Joint Hypermobility, Pain, and Early Degenerative Change Joint hypermobility exists across a broad spectrum and is found in both active and general populations. It refers to joints that move beyond expected physiological ranges because of differences in …

“Inter-individual variation in skeletal geometry, joint kinematics, and tissue properties drives unique alignment and movement strategies ‘neutral’ exists as a functional range, not a fixed state.”
