What type of exercise is used in the early phases of rehab when a joint is immobilized?

In the early phases of rehabilitation, especially when a joint is immobilized, isometric exercises are the recommended choice. Isometric exercises involve the contraction of muscles without any movement in the affected joint. This type of exercise helps maintain muscle strength and stability around the immobilized joint without placing stress on it.

During the initial stages of rehab, the primary goal is to prevent muscle atrophy and maintain some strength while allowing the joint to heal. Because there is no movement involved, isometric exercises can be performed safely in situations where range of motion is restricted, such as after an injury or surgical procedure where immobilization is necessary.

In contrast, dynamic exercises typically involve movement of the joint and are more appropriate in later phases of rehabilitation, when the joint has regained some range of motion and stability. Aerobic exercises usually require more mobility and are not suitable for the early stages of rehabilitation when a joint is immobilized. Flexibility exercises are also not recommended when a joint is under restriction, as they would require movement that could disrupt healing. Thus, isometric exercises are the most suitable and beneficial choice during this phase of the rehabilitation process.
