Institution Department Biomechanics Assessment and Gait Analysis The following is a report on biomechanical assessment and observational analysis of Cameron Bennet in respect to the function of lower limbs both in static and in motion in relation to gait. Biomechanics assessment is used to provide a larger comprehension of the function of the lower limb. Open kinetic chain (OKC) refers to the talus acting as an extension of the leg which allows the calcaneus to move then the forefoot to follow. Closed kinetic chain (CKC) is where the calcaneus moves in the frontal plane with limited transverse and sagittal plane motion as a result of reactions from the ground force. The main action of the foot is to assist in shock absorption and propel the body across the plane. OKC and CKC are vital in the assessment of both structural and functional characteristics of the foot. In close evaluation of Cameron’s functional and structural foot type the following clinically significant findings were known; Talar head palpation traverse for the rearfoot, frontal inversion of the calcaneus, traverse bulge of the forefoot in the region of the TNJ, flexible range of motion, subtalar joint (STJ), flexible first ray range of motion, loose mid tarsal joint (MTJ), and forefoot valgus due to size being small. A functional deformity can be seen in an open kinetic chain (OKC), non-weight bearing position, rather than a structural deformity. On assessment of Cameron’s OKC results it was determined that his STJ assessment indicated a loose quality of motion bilaterally due to his being hypermobile. A score of 8 was obtained on the Beighton-Carter-Wilkinson scale that confirmed hypermobility. A greater angle of ankle dorsiflexion was measured when the knee was in a flexed position as compared to when the knee was extended. The normal dorsiflexion of the knee is 10 and the results obtained
