What is the consequence of high calcium levels on muscle activity during rehabilitation for a stroke patient?

1. Increased muscle tone

2. Decreased coordination

3. Prolonged fatigue

4. No significant impact

The correct answer is: Increased muscle tone

High calcium levels in the body can lead to increased muscle tone, a condition also known as hypertonicity. This occurs because elevated calcium levels contribute to the excitability of muscle cells, making them more prone to contract. In the context of rehabilitation for stroke patients, increased muscle tone can result in stiffness and resistance to passive movement, which can significantly affect the patient's ability to perform movements and engage in therapy. When muscle tone is elevated, it can complicate therapy efforts aimed at improving mobility, coordination, and functional independence. Stroke rehabilitation often focuses on reducing spasticity and improving control of movement, so high calcium levels leading to increased muscle tone can pose challenges for therapists and hinder the overall rehabilitation process. Improving muscle relaxation through various therapeutic interventions may be necessary to counteract the effects of high calcium levels, facilitating better outcomes for the stroke patient. Understanding the impact of calcium on muscle tone is crucial for tailoring rehabilitation approaches effectively.
