There are a large number of different taping techniques that can be used for different anatomical locations.
Taping is used in two main areas:
In the acute phase immediately following an injury. This is to prevent further movement which may aggravate the injury and also to provide compressive support in an effort to control the amount of swelling.
During the active rehabilitation period to provide mechanical support and proprioceptive feedback to the damaged joint in an effort to reduce the risk of re-injury.
Your therapist may use taping to:
Decrease pain during sport or activity
Aid healing of injuries
Correct patella alignment
Allow an earlier return to sport or activity following injury
Reduce the likelihood of injury aggravation
Prevent injuries during high risk sports (such as netball, basketball, football, etc.)
