Introduction

Moving and positioning lie within the broader context of manual handling. Positioning is a key aspect of patient care. Optimum positioning is a good starting point to maximise the benefit of other interventions, such as bed exercises and breathing exercises; it can also assist rest and mobility, thereby facilitating recovery, enhancing function and preventing secondary complications. However, although it is important, it must not be seen in isolation and is just one aspect of patient management where the overall goal is to optimise independence.

In medical terms, ‘position’ relates to body position or posture, thus positioning involves placing the patient into a specific static alignment, which can involve their entire body, or just a single body part or limb.  Positioning can be achieved either;

• actively by the patient, meaning they are able to move under their own volition, or
• passively, where the patient is placed into a specific position with assistance of one or more other persons. 

A major challenge to positioning is trying to place a dynamic body into a prolonged static position. The human body was made for movement, it does not tolerate prolonged periods of immobilisation well. This means the positioning must be comfortable and allow the patient to reposition as needed, while maintaining the purpose behind the positioning. It is essential to frequently evaluate the effect that positioning is having on the individual to ensure that the intervention is helping to achieve the desired result or goal. Consider whether the positioning procedure is being clinically effective and, where possible, is evidence based.

Purpose of Positioning

The purpose and indications for therapeutic positioning vary depending on the patient population being treated. Positioning is indicated for patients who have difficulty moving or require periods of rest when normal function is impaired. Patients should always be encouraged to move themselves where possible, but where assistance is required they should to do as much of the movement as they can themselves.

Contraindications

There are no general contraindications for positioning; however, some positions are contraindicated for specific conditions or situations, most typically seen within hospital settings, particularly in Intensive Care Units or on post surgical wards;

Prone	Trendelenburg	Reverse Trendelenburg
Absolute Contraindication Unstable Spinal Fracture or Spinal Instability Acute Bleeding (eg, Hemorrhagic Shock, Massive Haemoptysis) Raised intracranial pressure >30 mmHg or cerebral perfusion pressure <60 mmHg Tracheal Surgery or Sternotomy within two weeks	Intracranial Pressure (ICP) > 20 mm Hg Patients in whom increased intracranial pressure is to be avoided (eg, neurosurgery, aneurysms, eye surgery) Uncontrolled Hypertension Distended Abdomen Oesophageal Surgery Recent gross haemoptysis related to recent lung carcinoma treated surgically or with radiation therapy. Uncontrolled airway at risk for aspiration (tube feeding or recent meal)	Hypotension Vasoactive Medication
Relative Contraindication Raised Intracranial Pressure >30 mmHg or Cerebral Perfusion Pressure <60 mmHg Haemodynamic Instability Unstable Pelvic or Long Bone Fractures Open Abdominal Wounds

Clinical Considerations

• Baseline Posture
• Sources of Pressure
• Orthopaedic Considerations
  • Weightbearing Status
    • for lower or upper extremity: this is important for patients who assist in their repositioning to limit or avoid WB through the involved extremity.
  • Total Knee Arthroplasy
    • In supine, a pillow or roll should not be placed under the surgical knee. Evidence does suggest use of inactive CPM with hip and knee flexion of 30° may mitigate knee swelling and minimise blood loss, leading to early rehabilitation and improved post operative range of motion. Weightbearing through the surgical knee, such as in kneeling, should be avoided until the incision line is well healed and pain controlled.
  • Total Hip Arthroplasty
    • Associated movement precautions based on the method of surgical replacement.  Traditionally, these precautions stay in place for 6 weeks following the joint replacement, although current evidence does not support the routine use of these hip precautions for patients status post total hip arthroplasty for primary hip osteoarthritis to prevent dislocation.
      • Anterior Approach - Avoid hip external rotation, active abduction and flexion beyond 90°
      • Posterior Approach - Avoid hip internal rotation, adduction across midline, and flexion beyond 90°
      • Lateral Approach - Avoid hip external rotation, active abduction, and extension
  • Transtibial/Below Knee Amputation
    • Avoid shortening of hip and knee flexors
  • Transfemoral/Above Knee Amputation
    • Avoid shortening of hip flexors, abductors, and external rotation
  • Sternal Precautions
    • Following open heart surgery: Avoid shoulder flexion above 90 degrees, shoulder external rotation beyond neutral, and shoulder abduction past 90 degrees.  If patient able to reposition themselves, avoid excessive pulling or pushing with their upper limbs and one-sided upper limb activity.
  • Spinal Precautions
    • Following Spinal Surgery - Avoid forward flexion, maintain shoulders and hips in alignment with no rotation. 
    • Following Cervical Surgery - Avoid pillow under head/neck to prevent forward flexion of cervical spine.
    • Spinal Bracing - If required be aware of amount of bed elevation allowed before the brace must be applied - ensure regular pressure checks as brace can act as a source of pressure.
  • External Fixation
    • Bulky and Heavy - Impact Independent Positioning
    • Oedema Management - Require Elevation
• Neurological Considerations
  • Tone
    • Spasticity - Can limit positions available for therapeutic interventions secondary reduced ROM or tonal fluctuations
    • Flaccidity - Increased subluxation risk with improper positioning and require assistance with repositioning
    • Splints - Support tone management or extremity protection with proper alignment but can be source of pressure
  • Cognition
    • Can the patient understand the purpose behind the therapeutic positioning? 
    • Do they know when to call for assistance? 
    • Are they safe to be left in a specific position?
  • Sensation
    • Has the patient got impaired sensation? If so may not be able to feel the effects of prolonged immobilisation
• Cardiorespiratory Considerations
  • Aspiration Risk
    • Aspiration is when food, liquid, or some other foreign material enters the airway and lungs. Patients with a known aspiration risk should have the head of the bed elevated to at least 30 - 45 degrees for up to an hour after eating.
  • Pacemaker Precautions
    • To protect the newly implanted device, which has leads interacting with cardiac tissue are the same for sternal precautions with the additional precaution of limiting reaching behind the patient’s back such as a movement like fastening a bra strap.
• Circulation Considerations
  • Odema Management
    • Depending on the level of edema present, edematous limbs will require elevation – ideally above the level of the heart.  This needs to be taken into consideration when prioritizing other therapeutic positioning interventions.
• Mobility
  • Can the patient assist in their positioning, or will one or more staff members be required to assist? 
  • Will the patient be able to perform adequate pressure relief independently? 
  • Can they reach the call bell to call for assistance?

Principles of Positioning

When approaching any therapeutic intervention, it is important to fully assess your patient before proceeding with therapeutic positioning. A patient should never be placed in a static position which will cause them harm or pain. The main principles underpinning all interventions involving patient positioning should focus on their short‐ and long‐term goals of rehabilitation and management for each specific patient. It is imperative that a thorough assessment is carried out prior to any intervention in order to plan appropriate goals of treatment. Wherever possible, goal setting should be a joint patient and healthcare professional discussion. It may be necessary to compromise on one principle, depending on the overall goal.

Regular reassessment is necessary to allow for modification of plans to reflect changes in status. Communication and involvement of the multidisciplinary team will assist rehabilitation interventions as treatment can be incorporated during positional changes. This potentially allows an opportunity for multip-rofessional working and allows many individuals to act with a common purpose and with co‐ordinated activity.

Common Positions

Conclusion

Positioning is a useful therapeutic tool that can be individualised to a patient’s unique needs and limitations.  It is a natural continuation of the assessment skills you have reviewed in previous courses.  While positioning can appear simple and straightforward at the surface, I hope this course has provided some insight into the skill and mindfulness that goes into effective and safe positioning.
