Chapters & learning objectives

Pathophysiology of Muscle Injury

1. Pathophysiology of Muscle Injury

This chapter will go over normal muscle anatomy and how it functions. We will review the sliding filament theory and the interaction between actin and myosin. Next, it will provide information on how myofibrils function during different contraction types and their response to injury.

Muscle Injury Types

2. Muscle Injury Types

This chapter will review the different types of muscle injuries. In addition, it will review the Microtrauma at the site of injury, the mechanism of injury, the symptoms of injury, the physiological repair process of muscle and its risk for further injury.

Muscle Strain Macrotrauma

3. Muscle Strain Macrotrauma

This chapter will go over the Macrotrauma of muscle strain. It will provide valuable clinical information on how to create an optimal healing environment for the muscle to get better. Early treatment strategies will be provided for the clinician.

Early and Late Treatment Guidelines

4. Early and Late Treatment Guidelines

The goal of this chapter will be to provide the reader with advanced principals for rehabilitating muscle injury. This chapter will go over the new principal of lengthened state eccentrics as a mechanism for prevention of a reinjury by shifting the length tension curve.
