Comprehensive Overview of Assistive Devices and Ambulation Techniques

QUESTION

1. Discuss the following assistive devices (level of stability/patient that would benefit from each, how to properly fit each to a patient, etc.) . Walker, Axillary Crutches, Forearm/Lofstrand Crutches, Cane 2. Define and Describe each weight bearing status (NWB, TTWB, PWB, WBAT, FWB) 3. Recommend an assistive device for the following patients. . Mr. Michaels is an active 27 yo male with injured his R ankle while playing basketball. The doctor in the ER has recommended he be NWB on R LE for 1 week. He lives in a 2-story walk-up apartment with no elevator. He works out of his very small, confined apartment. . Mrs. Adele is a 78 yo female who is now 1-day s/p R TKA. She has significant pain and swelling in her R knee and requires assistance for bed mobility and transfers. She is currently WBAT. . Mr. Jones is a 74 yo male who is currently being seen in outpatient PT for recent balance issues. He states he has not yet fallen, but often loses his balance just walking around the house. He comes to PT independently and does not currently use an assistive device. He enjoys walking in his neighborhood and wants to continue this but feels a bit unsteady. 4. Explain how you would instruct a patient to use a unilateral assistive device, and provide a rationale for your instructions. 5. Describe how you would guard a patient ambulating on a level surface or on stairs and when moving from a sitting to a standing position and from a standing to a sitting position. 6. Describe how you would monitor a patient’s response to ambulation activities and how you would use the findings to plan the patient’s treatment.

ANSWER

 Comprehensive Overview of Assistive Devices and Ambulation Techniques

Introduction

Assistive devices play a crucial role in promoting mobility and independence for individuals with varying levels of physical challenges. Proper selection and usage of assistive devices are essential for ensuring safety and optimizing functional outcomes. This essay will discuss different types of assistive devices, weight-bearing statuses, recommendations for specific patient scenarios, instructions for using unilateral assistive devices, guarding techniques, and monitoring patient response during ambulation activities.

Assistive Devices and Their Applications

Walker
Level of Stability: High stability; suitable for individuals with impaired balance or lower extremity weakness.
Patient Profile:Elderly, those with neurological disorders, post-surgery patients.
Fitting:Adjust walker height so that patient’s elbows are slightly flexed when holding the handles.

Axillary Crutches
Level of Stability: Moderate stability; individuals with non-weight bearing status.
Patient Profile: Those with temporary injuries, post-surgery patients.
Fitting: Crutches should be adjusted to ensure two to three fingers fit between the axilla and top of the crutch.

Forearm/Lofstrand Crutches
Level of Stability: Moderate stability; allows more arm movement than axillary crutches.
Patient Profile: Individuals with good upper body strength, long-term users.
Fitting: Adjust crutch height so that the cuff rests 1-1.5 inches below the elbow.

Cane
Level of Stability:Low stability; provides minimal support.
Patient Profile: Mild balance issues, slight lower extremity weakness.
Fitting: Length should be adjusted so that the cane handle aligns with the patient’s wrist crease when standing.

Weight-Bearing Status

NWB (Non-Weight Bearing): No weight is allowed on the affected limb.
TTWB (Toe-Touch Weight Bearing): Minimal weight allowed; only the toes touch the ground.
PWB (Partial Weight Bearing): Limited weight allowed; usually expressed as a percentage.
WBAT (Weight Bearing as Tolerated): Patient can bear full weight as long as it is comfortable.
FWB (Full Weight Bearing): Patient can fully bear weight on the affected limb.

Recommendations for Patients
Mr. Michaels: Knee Scooter or Hands-Free Crutch; suitable for stairs and small spaces.
Mrs. Adele: Standard Walker with Front Wheels; offers stability post-total knee arthroplasty.
Mr. Jones: Single-Point Cane; provides balance support during neighborhood walks.

Instructing Patients for Unilateral Assistive Device Use

Provide clear step-by-step instructions:
Gait Pattern: Demonstrate correct gait pattern (e.g., tripod gait) for stability.
Weight Shift: Instruct patient to shift weight to the assistive device side before stepping with the affected leg.
Stairs: Teach how to use the unaffected leg to step up first and the affected leg to step down first.

Guarding Techniques

Level Surface: Stand slightly behind and to the side of the patient, ready to catch them if they stumble.
Stairs: Stand in front of or behind the patient based on ascent or descent.
Sitting to Standing: Assist by providing a steady hand and verbal cues.
Standing to Sitting:Assist patient in bending at the hips and knees before sitting.

Monitoring Patient Response
Observe for signs of fatigue, shortness of breath, or dizziness during ambulation.
Monitor gait pattern, balance, and weight-bearing compliance.
Document any difficulties or improvements and adjust the plan accordingly.

Conclusion

Assistive devices play a vital role in enhancing mobility and quality of life for individuals with various physical limitations. Proper selection, fitting, and training are essential for maximizing their benefits. Understanding weight-bearing statuses, providing patient-specific recommendations, offering clear instructions, implementing guarding techniques, and monitoring patient response are integral aspects of effective ambulation and rehabilitation strategies.
