Mechanical Immobilization
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Mechanical Immobilization
• Some people are inactive and physically immobile due to
overall debilitating conditions.
• Others have impaired mobility resulting from trauma or
its treatment.
– Orthoses
• Orthopedic devices used to support or align a body
part and prevent/correct deformities
• Splints,immobilizers, braces, slings, casts, etc.
• Caring for individuals with orthopedic devices requires
specialized training
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Purposes
• Most who require mechanical immobilization have
suffered trauma to the musculoskeletal system
• Such injuries are painful and heal slower than injuries to
soft tissue
• Require a period of inactivity to allow new cells to restore
integrity to damaged structures
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Purposes
• Mechanical immobilization of body part is
used to accomplish the following:
– Reduce pain and muscle spasms; support
and align skeletal injuries
– Restrict movement and maintain
functional position while injuries heal;
allow activity while restricting movement
of injured area
– Prevent further structural
damage/deformity
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Mechanical Immobilizing Devices
• The use of various devices can achieve
therapeutic benefits
• Examples include splints, slings, casts, and
traction
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Splints
• Splints
– Device to immobilize/protect an
injured body part
– Used before or instead of casts
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Splints
• Splint types include:
– Emergency
• First aid for suspected sprains/fractures
– Commercial
• More effective than improvised splints
• Variety of designs depending on injury
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Splints
– Inflatable
• Also called “pneumatic splints”
• Become rigid when filled with air
• Limit motion, control bleeding/swelling
• Injured part inserted into deflated splint
• Air infused and splint molds to injured body part
• Fill to point which allows indentation with
fingertips
• Injury should be checked and treated within
30-45 minutes after application
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Splints
– Traction
• Metal devices that immobilize and pull on
contracted muscles
• Not as easy to apply as inflatable splints
• May require special training for application to
prevent further injury

Ambulatory Aids
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
• Debilitated clients require physical
conditioning before they can ambulate
again
• Some techniques for increasing strength
and weight bearing include
– isometric exercises for lower limbs
– Isotonic for upper arms
– Dangling at bedside
– Use of a tilt table
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Preparing for Ambulation
• Isometric exercises:
– Promote muscle tone and strength
– 2 types include:
– Quadriceps setting: client alternately tenses and
relaxes the quadriceps muscles
– Gluteal setting: client contracts and relaxes the
gluteal muscles to strengthen and tone them
Easily performed in bed or chair
Initiated long before ambulation begins
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Quadriceps and Gluteal Setting
Exercises
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Preparing for Ambulation
• Upper arm strengthening: flexion and
extension of the arms and wrists; raising and
lowering weights with the hands; squeezing
a ball or spring grip; modified hand push-ups
in bed
• Dangling: normalizes blood pressure
• Using a tilt table
Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
Assistive Devices
• Devices to support and assist walking:
– Parallel bars (handrails) provide practice
in ambulating
– Walking belt applied around client’s
waist provides secure grip to prevent
injury while ambulating
