Bed mobility activities are designed to adjust the body position of a recumbent patient to prevent the development of joint contractures or skin breakdown. In contrast, depending on the patient's medical condition, such as after total joint replacement, there may be mobility restrictions or contraindications that affect bed mobility.
A number of medical conditions can result in mobility and position restrictions or contraindications. These include:
This patient population is prescribed a positioning device, a triangular foam cushion, which is strapped between the legs to keep the hip in an abducted position. It is important to remember that these range-of-motion restrictions apply in relation to both hip and trunk motion. For example, both lifting the knee while sitting or leaning forward at the waist result in hip flexion beyond 90°. From a clinical perspective, extra care must be taken when the patient is moving from supine to sitting to prevent both excessive hip flexion and excessive hip adduction.
Hemiplegia: rolling from supine to sidelying on the hemiplegic side is relatively straightforward, but rolling to lie on the stronger side presents a greater challenge.
Spinal cord injury (SCI): the functional ability of the patient who is post SCI depends on the level and degree of injury (Table 10-1). With respect to bed mobility, an injury at the level of the sixth cervical vertebra (C6) will typically allow a patient to achieve independent performance of bed mobility.
