1
Q

What is a therapeutic exercise?

A

Systematic, planned performance of bodily movements, postures, or physical activities intended to provide a patient/client with the means to:
• Remediate or prevent impairments
• Improve, restore, enhance physical function
• Prevent or reduce health-related risk factors
• Optimize overall health status, fitness & sense of well being

138
Q

  • Proprioceptive Neuromuscular Facilitation (PNF)
146
Q

What is static/passive stretching?

“Relaxed stretching”, One where you assume a position and you hold it with some other part of the body or with the assistance of a partner or an apparatus(can be the floor)

147
Q

A

Typically 3 sets of 20-30 seconds

148

152
Q

There is none. It is neither safe nor indicated and can be harmful

153
Q

What are the things associated with ballistic stretching?

A

Decreased performance, and more muscle injuries

154
Q

What is dynamic stretching?

A

The involvement of moving parts of the body, gradually moving to increase reach, speed of movement, or both

155
Q

What does dynamic stretching consist of?

A

Controlled leg and arm swings that take you gently to the limits of ROM.

156
Q

What is PNF stretching?

A

The integration of active muscle contractions into stretching in order to either inhibit or facilitate muscle activation and increase the likelihood of the muscle to be lengthened while remaining relaxed as its stretched

157
Q

What is the traditional underlying mechanism of PNF?

A

The reflexic relaxation occurs during the stretching maneuvers as a result of the autogenic reciprocal inhibition, thus leading to decreased tension of muscle fibers, therefore decreased resistance, and increased elongation by the contracture elements of muscle when its stretched

158
Q

What is the modern underlying mechanism of PNF?

A

Sensorimotor processing, which is a combination of visco-elastic adaptation of the musculo-tendinous unit as well as changes in the patients tolerance of the stretching maneuver

159
Q

What are the basic PNF stretches?

A
  • Hold- Relax
  • Contract - relax
  • Hold relax with agonist contraction
160
Q

How does hold- relax PNF stretch work?

A

After assuming a passive stretch, the muscle being stretched is isometrically contracted for anywhere between 6-15 secs, and then the muscle is briefly relaxed for another 2-3 secs, then passively stretch the muscle even further than it was before and hold for the same amount of time

161
Q

How does contract- relax PNF stretch work?

A

There is a concentric activation of the muscle being stretched, and there is active movement

162
Q

How does hold relax with agonist contraction PNF stretch work?

A

Identical to hold relax, but in the 3rd phase, there is concentric action of the agonist muscle in addition to passive stretch to add more force. Final stretch should be greater

163
Q

___ and ___ stretching tends to induce small to moderate decreases in performance for short term after stretching

A

Static and PNF stretching tends to induce small to moderate decreases in performance for short term after stretching
