Exercise Therapy MCQS | part #1

1. d ) Law of Parallelogram: - Draws a parallelogram with the two exercise vectors as sides. - The resultant vector is the diagonal of the parallelogram. This method accurately determines the combined effect of multiple exercises in exercise therapy. 2. a) 35 kg Traction Force: . 40 kg force applied at an angle of 30 degrees. . Effective distal force (F) = Traction force (T) x cos(θ). Calculation: F = 40 kg x cos(30°) = 40 kg x 0.866 = 34.64 kg ≈ 35 kg 3. d) All of the above. Force opposing motion between two surfaces in contact. Depends on: - Area of surface in contact (directly proportional) - Nature of the surface (surface roughness, texture) - Weight (normal force) of the moving object (directly proportional) 4. d) All of the above. Mechanical devices changing the direction or magnitude of force. Used to: - Make work easier (mechanical advantage) - Alter the direction of motion - Gain mechanical efficiency 5. b) 90 degrees to the moving bone. At 90 degrees, the force applied to the pulley is perpendicular to the moving bone, resulting in maximum resistance. Optimal mechanical advantage: 90-degree angle provides the greatest mechanical advantage, maximizing the resistance force. 6. c) 3rd. 3rd-class lever: Speed multiplier (e.g., fishing rod) - Fulcrum at one end, load at the other - Speed increases, force decreases 7. C) Third-order lever. Knee Flexion in Prone Lying: - Fulcrum (pivot point): Hip joint or lower back - Effort (force): Hamstring muscles contracting - Load (weight): Lower leg and foot 8. D) Efficiency. 2nd-Class Lever: - Fulcrum at one end - Effort at the other end - Load between fulcrum and effort Characteristics: - Mechanical advantage: Multiplies force, making tasks easier - Efficient use of energy: Less effort required for a given load 9. C) Third order lever Standing on Toes: - Fulcrum: Ankle joint - Effort: Calf muscles contracting - Load: Body weight 10. C) Third-Class Levers: Most abundant in the human body e.g Elbow joint , Shoulder joint , ,Knee joint, Ankle joint. Third-class levers: - Amplify speed and range of motion - Suitable for precise, quick movements - Efficient for daily activities (e.g., walking, running, grasping) 11. b) Second-Class Lever: - Known as the "lever of power" - Characterized by: - Fulcrum at one end - Effort at the other end - Load between fulcrum and effort - Multiplies force, but reduces speed 12. 13. b) The brachioradialis muscle elbow flexion remains a 3rd-class lever, optimized for speed. and precision. 14 b) 2. MCP (Metacarpophalangeal) Joint of Finger: - Degrees of Freedom (DoF): 2 - Movements: 1. Flexion/Extension (1 DoF) 2. Abduction/Adduction (1 DoF) 15. Sagittal plane and frontal axis. Ankle Dorsiflexion and Plantarflexion: - Movement plane: Sagittal plane (anteroposterior) - Axis of rotation: Frontal axis (mediolateral) keywords MCQS, physiotherapy , education, ppsc ,NTS , physiotherapy license exam, haad , MOH, DHA, exercise therapy, #physiotherapyvideos #medicalquestions #physio #medicalmcq #medicalvoltage #drnidailahipt #exercisetherapy #therapeuticexercise #movementtherapy
