Orthotic fitter exam study guide QUESTIONS WITH COMPLETE 100% VERIFIED SOLUTIONS 2024/2025 What muscles make up the hamstrings semimembranosus, semitendinosis, bicep femoris Chondromalasis patella may be caused by over pronated foot, weak vastus medialis obliquis, weak gluestus medius What is Bursistis Inflammation of the bursa, causing swelling and pain What are bursa fluid filled sacs between tissues What is eccentric controlled movement in which you move toward an opposing force, rather than away. Lengthening of the muscle Example of eccentric muscle contraction lowering a weight, walking down stairs What is apropulsive gait foot drop, partial foot amputation or soft tissue dysfunction Proprioception rehabilitation can on occur during controlled motion when weight bearing Normally____, when torn loose by a sudden ____, seldom break in the middle rather, they _____ away from the _____ at the _____ Normally tendons, when torn loose by a sudden force, seldom break in the middle rather, they pull away from the bone at the end What is antalgic gait a gait in which the stance phase is shorter than the swing phase. It is a good indicator of weight bearing pain What is Ataxic gait an unsteady, uncoordinated walk with a wide base and the feet thrown out, coming down first on the heel and then the toes with a double tap What is the popliteal fossa cavity posterior to the knee What is the function of the skeletal system to provide a flexible foundation and manufacture red blood cells What is a shoulder joint ball and socket joint, muscle dominated joint and can move in all planes Joint stability requires adequate strength, appropriate ROM and adequate proprioception What is a closed kinetic chain a series of connected joints in which the distal segment is in fixed, weight bearing position. Orthotics can aid in eccentric muscle activity, reactive muscle activity and concentric muscle activity What is concentric muscle activation (contraction) that causes tension on your muscle as it shortens, generating enough force to move an object Example of concentric muscle contraction Bicep curl What is double-step gait a gait in which there is a noticeable difference in length/timing of alternate steps What are sacomeres overlapping work units within muscle structures How can the posterior cruciate ligament can be injured excessive ankle dorsiflexion and a so called dash-board injury. What is Chondromalasis of the patella roughening of the articulating surface of the patella What is an articulation forms a joint What is a collateral ligament any ligament running along the medial/lateral sides of a joint The foot/ankle complex serves what 3 purposes flexible adaptor to the terrain, flexible stabilizer during ROM and a rigid lever arm to propel off the terrain What is pronation motion in 3 joints at the same time in 1 plane What is Drag-to gait gait in which feet are dragged rather than lifted toward the crutches What is Haglands deformity a bone protuberance at the back of the heel that can be inflamed and cause pain. Usually occurs with high arched feet or high heeled shoes. AKA - Pump-bump Functional Orthotic semi-rigid balancing device designed to slip inside the shoe and control abnormal motion of the foot/ Device is made by taking a mold while it is held in the correct position What is proprioception LCL, on the lateral side of the knee joint, limits the amount the knee moves from side to side anterior cruciate ligament ACL, on the anterior part of the knee, stops the tibia from moving forwards in front of the femur posterior cruciate ligament PCL, on the posterior side of the knee joint, control the forward and backward movements of the knee anterior talofibular ligament ankle sprain ligament, most often damaged when the ankle is rolled, stabilizes the ankle joints and keeps it from rotating inward deltoid ligament fan shaped band of connective tissue on the medial side of the ankle, take a lot of force to tear calcaneofibular ligament starts at the tip of the fibula and runs along the outside of the ankle into the calcaneous posterior talofibular ligament runs from the back lower part of the fibula and into the outer back portion of the calcaneous, stabilizes the ankle and subtalar joints anterior inferior tibial fibular ligament high ankle sprain ligament, positioned on the lower front of the ankle and helps keep tibia and fibula together interosseous membrane made of strong fibrous tissue and runs along the tibia and fibula and keeps them moving as one unit plantar calcaneonvicular ligament spring ligament on the underside of the foot that connects the calcaneus with the navicular plantar aponeurosis plantar fascia, layer of fascia along the sole of the foot, maintains the foots arch what are the joints of the foot and ankle ankle, talocrural, chopart joint, lisfranc, metatarsalphalengeal, interphalangeal joint what are the ankle joints posterior talofibular, anterior interior tibiofibular, anterior talofibular, deltoid, calcaneofibular origin of a muscle where is begins insertion of a muscle where it ends longus lower leg muscles that evert the foot also abduct the foot muscles that invert the foot also adduct the foot movements in the toes flexion, extension, abduction and adduction hallucis foot hallux great toe extrinsic muscles move the entire foot intrinsic muscles move the toes/ support the arch gastrocnemius above medial condyle of femur plantarflexes the ankle, stabilizes knee and ankle when standing, soleus upper fibula, plantar flexes the foot plantaris above lateral head of gastrocnemius of femur, plantar flexes the foot popliteus lateral femoral head, laterally rotates femur on tibia and unlocks the knee flexor digitorum longus flexes the 2nd-5th toes posterior tibialis stabilizes ankle, inversion and adduction of foot flexor hallucis longus flexes the big toe peroneus longus eversion and abduction of the foot peroneus brevis eversion and abduction of the foot
