When the force exerted on one body levers by muscular action is insufficient for the production or control of movement, an external force may be added to augment it. Such type of exercises are known as active assisted exercises.
This presentation includes all the required information that a first year BPT student should know.

I hope this content helps you in understanding this condition. Thank You for sparing your precious time and going through this PowerPoint presentation.
3. Principles of Assistance
▪ When the force exerted on one body levers by muscular action is
insufficient for the production or control of movement, an external
force may be added to augment it.
▪ External force must be applied in the direction of the muscle action
but not necessarily at the same point, as a mechanical advantage can
be gained by increasing the leverage.
▪ The magnitude of assisting force must be sufficient only to augment
the muscular action and must not be allowed to act as a substitute.
▪ NOTE: Power of muscle increases, assistance must be decreased
proportionally.
5. Starting Position
•Should be stable so the patients who attention is concentrated on the pattern of movement and the effort
required to perform it.
Pattern of Movement
8. Effects and Uses
i. Early stages of neuro-muscular re-education
ii. Improving co-ordination
iii. Boosting confidence
iv. Maintaining movement in spite of pain in joint
v. Increase range of motion
9. Contraindications
i. Immediately post injury- to avoid further damage.
ii. Early unstable fracture
iii. Intolerable pain
iv. Intolerable muscle/ ligament tear
v. Compromised circulation (Example: DVT)
vi. Unable to co-operate with technique
