Postural supports are specifically designed to assist individuals in achieving proper body positioning, balance, and alignment. These devices can include items such as cushions, restraints, or supports that help maintain the body in a neutral position, preventing discomfort and potential injury from poor alignment. The use of postural supports is particularly important in health care settings where patients may be immobilized or have limited mobility, as maintaining proper posture can aid in overall comfort and support bodily functions.

While the other options listed serve important functions in medical care, they do not directly relate to body positioning or alignment. An IV pump is used to deliver fluids and medications intravenously, and an ECG machine is utilized to monitor the heart's electrical activity, neither of which contributes to positioning. A postural corrector may be beneficial, but it is more specific to alignment correction and doesn't encompass the broader range of devices used for support as effectively as postural supports do.
