Rehabilitation Sciences Test Bank
Course Introduction
Rehabilitation Sciences is an interdisciplinary field that focuses on the study and application of theories and techniques to restore, maintain, and enhance physical, cognitive, and social function in individuals affected by injury, illness, or disability. Emphasizing evidence-based practice, this course explores topics including human movement, neuroscience, psychology, and health care systems, and introduces assessment and intervention strategies used by professionals such as physical therapists, occupational therapists, and speech-language pathologists. Students will gain an understanding of the holistic and patient-centered approaches that guide rehabilitation processes and prepare them for roles in clinical, research, and community settings dedicated to improving health outcomes and quality of life.

Sample Questions
Q1) As your patient abducts her shoulder from 90° to 120°,the moment arm decreases.If the torque from the deltoid remains constant,the force of the deltoid would ________________as the shoulder abducted.
A) remain the same
B) increase
C) decrease
D) become 0 N
Answer: B
Q2) The relative line of gravity changes with changes in body position.
A)True
B)False
Answer: True
Q3) Explain how anatomical pulleys affect the magnitude and direction of a muscle force (Fms).
Answer: Anatomical pulleys (always single pulleys)do not affect the magnitude of Fms but do change the direction of pull.The change in action line generally brings the action line away from the joint axis,thus increasing the moment arm or rotatory component of the applied force.

Sample Questions
Q1) How is the synovial fluid within a joint formed? Of what is it composed?
Answer: Synovial fluid,which is produced by the synovial layer of the capsule,is composed primarily of plasma and hyaluronic acid,with a glycoprotein called lubricin.Hyaluronate is responsible for reducing friction between the synovium and joint surfaces,and lubricin reduces friction between the joint surfaces (cartilage-on-cartilage).
Q2) What are the characteristics of viscoelasticity,and which of the following tissues exhibits viscoelasticity: ligaments,tendons,hyaline cartilage,fibrocartilage,or bone? Answer: Viscoelastic materials exhibit elasticity (ability to deform and return to its original shape immediately)and viscosity (ability to resist shear).Viscosity gives the tissues time and rate-dependent properties; that is,the deformation response of the tissue varies according to the duration of load and the rate of load.Each of the tissues listed above is viscoelastic.
Q3) Define stress and strain.
Answer: Stress is the force applied to a tissue per unit area.Strain is the deformation that occurs in a tissue in response to an applied stress and is expressed as the change in shape (length,width)over its original shape (length or width).Stresses and strains may be tensile,compressive,shear,or torsional.

Sample Questions
Q1) What must happen before a motor unit will fire (discharge)? What occurs immediately after discharge of the motor unit?
Answer: In order for a motor unit to discharge,there must be sufficient facilitation (buildup of charges)at the anterior horn cell (AHC).Once threshold is reached,an impulse is conducted down the axon and all innervated fibers contract.Immediately after firing and fiber contraction,the motor unit goes through latency,or a refractory period,during which depolarization cannot occur.
Q2) What protects the muscle from overcontraction or overstretch? What "monitors" length of a muscle?
Answer: Overcontraction and overstretch are prevented by the "abort" receptors,the Golgi tendon organs (GTOs).It is generally believed that these will not fire unless there is a reasonable threat to the muscle.The active and passive lengths of a muscle are monitored by the muscle spindle.It is the spindle that is responsible for a muscle's tone,or resistance to passive stretch.
