KIN-10 Lecture Notes - Lecture 12: Plantar Fasciitis, Chondromalacia Patellae, Basic (Dance Move)
Document Summary
Characteristics of walking gait in older adults. Shorter step length and relative swing time. Decreased maximum walking speed, joint range of motion, and cadence. Increased base of support, double limb support, and use of visual scanning. Does not gave a period of double support. Alternating periods of single support separated by a double float phase of flight phase. Trendelenburg gait: weakness or paralysis of hip abductors resulting in pelvic drop on contralateral side. Acl deficiency altered gait mechanics and compensatory adaptations, including a quadriceps avoidance strategy. Cerebral palsy (cp) nonprogressive condition of muscle dysfunction and paralysis caused by brain injury at or near birth resulting in gait with abnormally flexed, adducted, and internally rotated hips, hyper-flexed knee. Gluteus maximus active at end of swing phase to slow hip flexion. Hamstring active in late swing to slow knee extension. In early stance, gluteus maximus, quadriceps, and gastrocnemius active to resist flexion of lower extremity joints.
