Five Prerequisites of Gait (Ans- -stability in stance -clearance in swing -preposition of the foot in terminal swing -adequate step length -energy conservation Three Goals of TT Biomechanics (Ans- -Increase weight bearing capacity -Maintain ML stability at midstance on prosthetic side by providing a varus moment -encourage knee flexion throughout the stance phase on the prosthetic side TT Biomechanics - Increased Weight Bearing (Ans- -load pressure tolerant areas and relieve pres...

What are the benefits of having a lower AP trim line on a socket? (Ans- Reduces resistance to hip flexion/extension and allows for more muscle bulk What are the advantages/disadvantages of a partial suction socket? (Ans- Advantages: limb volume adjustment, good for initial prosthesis Disadvantages: requires auxiliary suspension What are the advantages/disadvantages of a total suction socket? (Ans- Advantages: very secure, less bulky Disadvantages: minimal adjustment possible If a sock i...

What are the two most common contractures with a transfemoral amputee? (Ans- hip flexion, hip abduction When do you begin transfer training with a transfemoral amputee patient? (Ans- day 1 What is the treatment plan for a post transfemoral amputation? (Ans- - Day 1 = transfer training - Rigid dressing post op - Stump shrinker post suture removal (3wks) - Prosthetic dependent on healing What positional education should you really emphasize with a transfemoral amputee patient? (Ans- ...

What happens at the knee if the COG is anterior to the ankle joint? (Ans- Knee extension What are 3 benefits of flexing the socket 5-15°? (AnsMaintains IT on posterior brim (quadrilateral socket) Increases weight bearing on posterior wall (more tolerant) Helps generate extension more easily (puts glutes on stretch) What are 3 benefits of adducting the socket about 10°? (AnsPlaces foot under pelvis for normal BOS Increases weight bearing on lateral wall (more tolerant) Helps Generate a...

What are the types of prosthetic knees available in order of least stability to most stability (likewise, most voluntary control to least voluntary control)? (AnsOutside hinges Single axis-constant friction Weight activated stance control Polycentric Manual locking What type of prosthetic knee is this describing? "Used with long residual limbs. Free motion in the sagittal plane. Exoskeleton designs. Least stability, most voluntary control." (Ans- Outside hinges What type of pro...

What are the four advantages to using anatomic suspension? (AnsEasy to don/doff Very efficient/functional design Pediatric patients and disarticulation Cost effective What type of suspension system is this describing? "A distal valve permits the air to escape, but does not allow air back in. Increases proprioception. Minimizes pistoning. However, if a person has excessive volume fluctuations or cannot complete donning, this suspension system isn't for them" (Ans- Suction suspe...

Which of the following amputation levels requires the highest energy expenditure when using the appropriate prosthesis? a. Vascular transfemoral amputation b. Traumatic transfemoral amputation c. Vascular transtibial amputation d. Symes amputation (Ans- a. vascular transfemoral amputation Which of the following transferal gait deviation would MOST likely be caused by knee bolt malrotation in external rotation? a. Hip hiking b. lateral heel whip at eh benign of swing phase c. Foot slap...

why is it important to know landmarks that are pressure tolerant vs. pressure intolerant = (Ans- redness in areas that are intolerant to pressure indicative of poor prosthesis fitting major weight bearing area w/ quadrilateral socket = (Ans- ischial tuberosity For quadrilateral socket, height of the posterior wall is at the level of (Ans- ischial tuberosity Disadvantages of quad socket (Ans- •Little or no ML control of pelvis •Un-stabilized femur in socket •Undue concentration ...

How many Salter-Harris classifications for physis fractures are there? (Ans- 5 (T1-T5) What area of bone does a T1 fracture impact? (Ans- physis only (growth plate only) What area of bone does a T2 fracture impact? (Ans- Physis and metaphysis What area of bone does a T3 fracture impact? (Ans- Physis and epiphysis What area of bone does a T4 fracture impact? (Ans- Physis, metaphysis, and epiphysis What does T5 fracture indicate? (Ans- a complete crush of the physis, the w...
