What factor related to the residual limb is crucial for ensuring proper alignment of a prosthetic device?

• Residual limb shape

• Body weight

• Footwear type

• Age of the patient

Which of the following best describes the purpose of the MRC scale in muscle testing?

• To evaluate joint stability

• To assess sensory perception

• To measure muscle power

• To determine bone strength

A transtibial socket that covers the knee is called a:

• Total contact socket

• Patellar tendon-bearing socket

• Supracondylar socket

• SACH socket

A pin/lock suspension system involves:

• Using suction for suspension

• Securing the residual limb with a pin

• Strapping the socket to the residual limb

• Securing the socket using laces

How does a polycentric knee unit differ from a single-axis knee unit?

• It allows only one type of movement

• It has a lower weight limit

• It provides greater stability

• It has multiple pivot points

A single-axis knee prosthesis is typically defined by:

• Simple mechanical design

• Enhanced stability

• Limited adaptability

• Low weight

What is the primary advantage of a single-axis knee unit?

• High stability

• Microprocessor control

• Enhanced energy return

• Increased pivot points

The K-level classification system is used to determine:

• Socket design

• Limb coloration

• Functional ability

• Residual limb length

A K3-level amputee has the potential to:

• Only walk on level surfaces

• Engage in high-impact sports

• Not use a prosthetic limb

• Perform only basic activities

What are the key factors in achieving optimal functionality with prosthetic limbs?

• Cosmetic appearance and socket fit

• Cost and durability

• Functional needs and user comfort

• Prosthetic foot design and socket material
