The Author: Vilma Gaucyte, II year student of VU Rehabilitation program Academic advisor: dr. Svetlana Lenickiene, Vilnius University, Department of Rehabilitation, Physical and Sports Medicine. Keywords: knee osteoarthritis, knee pain, backward walking, gait, knee adduction moment. The aim of research work: to evaluate the impact of backward walking in patients with knee osteoarthritis. Tasks of work: 1. To evaluate and compare the impact of backward and forward walking patterns on the damaged knee joint pain, range of motion and lower limb muscle isometric force. 2. To evaluate and compare the impact of backward and forward walking patterns on functional status and functional capacity. 3. To establish realations between differents knee function parameters. Materials and methods: This research was organised involving 30 outpatients with diagnosed II ° - IV ° degree of knee osteoarthritis in Vilnius University Hospital, Physical Medicine and Rehabilitation Centre from September 2015 to April 2016. Patients were randomly selected and divided into two groups: experimental and control. Participants performed a program of physical therapy lasting 10 days. An additional 10 min forward walking on monitorized tredmill was added to conrol group, while experimental group had additional 10 min backward walking on the same device.It was measured : active knee flexion and extension (up to the patient’s tolerated pain sensation), range of motion of active and passive knee flexion and extension, isometric strength of hip flexors and extensors, knee flexors and extensors, ankle flexors and extensors, functional status of lower extremity and lower functional capacity. Data analysis was performed using statistical analysis SPSS 20.0 for Windows and Excel 2010 programs. Results:This study estimated that results of patients' functional status belongs to strong linear relations correlated with pain sensation and isometric muscle strength of ankle flexors and extensors.Conclusions: 1.Physical therapy program supplemented by backward ant forward walking models decrease siginificantly pain sensation in the knee joint during flexion. It also increase significantly isometric muscle force of hip flexor, hip extensor, knee flexor, knee extensor, ankle flexor and ankle. The backward walking reduce significantly pain sensation in the knee joint during extension and increase isometric muscle strength of hip extensors and ankle flexors. 2.The physical therapy program, supplemented by backward or forward walking improved significantly functional condition of the knee joint and patients’ functional capacity. 3.Patients with knee osteoarthritis functional condition depends on the muscle strength of hip, knee, ankle flexors and extensors as well as on knee joit pain score. Damaged knee joint pain inverse relationship is related to the major lower extremity muscle group weakness, lower limb functional status and functional capacity limitations. |
