Final answer:
To help Sharon tone and strengthen her body with a herniated disc, gentle, controlled movements are recommended in Pilates. Lifting heavy objects can worsen herniation and cause limb pain due to increased spinal pressure. Controlled force and good posture in exercise are crucial for strengthening muscles without additional injury.
Step-by-step explanation:
The best method for Sharon's Pilates teacher to use in helping her achieve her goal of toning and strengthening, particularly with a herniated disc, is c) Gentle, controlled movements. Heavy resistance training and high-impact exercises could potentially exacerbate her condition, while dynamic stretching may not provide the targeted strengthening Sharon is seeking. It is critical to avoid exercises that can cause strain on the lumbar spine where the injury is located.
Lifting a heavy object can produce pain in a lower limb due to the increased pressure and shear forces exerted on the spine and the intervertebral discs. Such activities could worsen her herniation, increasing the risk of aggravating the sciatic nerve, which can lead to radiating pain in the lower limb.
It is essential for individuals with spinal injuries to maintain good posture and engage in exercise routines that strengthen muscles without undue stress on the spine and its supporting structures. Physical therapy exercises, especially those designed to be carried out in water, can significantly assist in this process by applying a controlled force and torque that strengthen muscles while minimizing the risk of further injury.
