Course Description

This program features an overview of somatosensory function and development, the role of postural control in movement acquisition and physiologic adaptation of neuromusculoskeletal tissues, and features of orthopedic development of the trunk and selected aspects of the extremities. The content has relevance to pediatric rehabilitation clinicians who set treatment goals and design management strategies to optimize upper and lower limb use in children with neuromotor dysfunction and deficits in sensory processing and postural control. 

The first two sessions span an overview of biomechanical, kinesiologic, and physiological sciences at work in orthopedic and sensorimotor development, both typical and pathologic. The operating mechanisms of movement-based modeling of the growing skeleton are reviewed and applied to children with unilateral and bilateral cerebral palsy, and to the upper extremity in children with brachial plexus palsy.  The mechanisms at work in the acquisition of - and the role of - postural control are reviewed in the context of building effective limb use, with suggestions for assisting a child to develop this essential foundation. 

Instructor describes selected musculoskeletal assessments and the clinical implications of their findings and brings them to therapeutic and orthotic management planning designed to optimize bone and joint development via building postural control and movement skills. The relevance of the findings obtained in the musculoskeletal assessment to target selected interventions is made evident in videotaped cases.

Course Objectives

Here is a partial list of course objectives. (See Course Description [link] for full list.) Participants completing this course are expected to be able to:

  • Describe these features of normal, postnatal immaturity of skeletal structure and alignment: thoracolumbar kyphosis, scapular and upper limb segment alignment, hip flexion contracture, increased femoral anteversion, increased femoral antetorsion, coxa valga, genu varum, and leg and foot rotation.

  • Distinguish between strain and load and apply this distinction to the skeletal modeling process and to modeling potential in an aging child.

  • Relate movement-based loading history to bone growth rate in children. Explain the significance of the innate drive for verticality.

  • Explain the presence of symmetry in supine and prone positions at age 4 months as evidence of fundamental postural control.

  • Describe how the normal neonatal hip flexion contracture influences the early modeling of the lumbar spine in the sagittal plane.

  • Relate ideal, full‐term neonatal lower limb joint alignment to the acquisition of skilled transitions between quadruped and sitting positions.

  • Relate the achievement of competent weight shifting in the frontal plane to emerging upper and lower limb use.

  • Describe the torsional status of the radius and ulna of the affected side in children with hemiplegic cerebral palsy.

  • Describe the upper limb modeling errors in brachial plexus palsy that limit shoulder lateral rotation and forearm supination.

  • Discuss the components of Targeted Training that apply to the enhancement of upper limb use.
