Formatted abstract
Bone sarcomas are the fourth most common cancer in individuals under 25 years of age. Limb salvage procedures have become increasingly popular for the treatment of osteosarcomas as they have functional and physiological benefits over traditional amputative procedures. The purpose of this study was to assess locomotor patterns post lower limb salvage surgery via electromyographic and energetic measurement techniques on a group of intra-articular knee osteosarcoma patients greater than one year post surgery. A retrospective outcome study was undertaken on 20 limb salvage patients (10♀, 10♂) recruited from the Queensland Bone Tumour Registry. Results showed prolonged activation of rectus femoris and prolonged co-contraction of the rectus femoris and hamstring muscles (p > 0.05) in the affected limb
of the limb salvage group compared to a control group. Prolonged rectus femoris activation and co-contraction was also evident in the unaffected lower limb suggesting alterations in gait programming within higher neuronal centres. The results are important for the development of rehabilitation programs as they suggest an overall reprogramming of the gait pattern, thereby limiting the impact of conventional strength and stretching interventions.
