During the pectoralis major length assessment, what does it indicate if a client feels stretch tension in the right pectoralis major?

If a client feels stretch tension in the right pectoralis major during the length assessment, it indicates stiffness or shortening in that muscle. This sensation suggests that the muscle is not able to reach its full extended position, which can be a sign of tightness or restrictions in length. When muscles are shortened or stiff, they can contribute to postural imbalances and may lead to compensation patterns that can affect movement and function.

In this context, identifying stiffness or shortening is critical for developing an appropriate corrective exercise program. The goal would be to address the flexibility of the pectoralis major to restore optimal function and alignment, which may involve specific stretching and strengthening exercises that target both the pectoralis major and any associated muscles.

The other options do not accurately describe the situation given the client's reported tension. Normal flexibility would indicate little to no stretch sensation, excessive mobility suggests that the muscle is too flexible and may contribute to instability, while joint instability refers to a lack of control around a joint rather than a specific muscle's flexibility. Recognizing stiffness and intervening appropriately is essential for effective corrective exercise programming.
