Lesson notes

Learning Objectives

Indicator: 2.3.2.LI.1 - Explain the use of prostheses and orthoses to manage, correct and treat disabilities.

By the end of the lesson, learners can:

Define prosthesis and orthosis in their own words and distinguish clearly between the two terms.
Identify at least four types of prostheses and four types of orthoses, stating the site of application for each.
Explain the causes of limb loss and functional impairment, including pathological effects, trauma, malformation and congenital loss.
Relate specific functional losses of the upper and lower limbs to appropriate prosthetic or orthotic solutions.
Justify the choice of a prosthesis or orthosis for a given patient case, considering the cause of the disability and the functional need.

Exemplars (from the NaCCA curriculum)

Exploratory Learning: Individually, conduct a research on the Internet about the usage of prostheses and orthoses.
Cooperative Learning: Engage in a class discussion to arrive on the definition and functions of prothesis and orthosis, using examples from videos, pictures and experiences of learners. Discuss the pathological effects of disease, trauma, malformation and loss of the lower and upper limbs and relate them to functional loss. Talk about examples of prostheses and orthoses and their sites of application.
Project-Based Learning: Learners research and identify examples of functional losses of the limbs, deduce whether these effects are as a result of pathological effects, trauma, malformation or loss of upper/lower limbs and propose solutions to these effects using prosthesis or orthoses.
Collaborative Learning: Make group presentations to the class based on the findings.
