Study Notes
Timing for Emphasis (TE) in PNF
- One technique used in Timing for Emphasis (TE) is the quick stretch, which involves a rapid increase in resistance to maximize muscle contraction.
Purpose of Resistance in PNF
- The purpose of using resistance in PNF is to facilitate muscle contraction, thereby increasing strength and promoting motor learning.
Overflow or Irradiation in PNF
- Overflow or irradiation in PNF refers to the spread of muscle contraction from one muscle group to adjacent muscle groups, resulting in increased muscle activity and strength.
Manual Contacts (MC) in PNF
- The purpose of using manual contacts (MC) in PNF is to provide proprioceptive input, facilitate muscle contraction, and enhance motor control.
Importance of Therapist Position and Body Mechanics
- Therapist position and body mechanics are important in PNF because they enable the therapist to effectively apply resistance, maintain proper body alignment, and reduce the risk of injury to both the therapist and the patient.
