“…The first loading pattern peaked at 300 N, which was kept the same over the healing period and used for validation of the model. The second loading pattern was created to simulate, in general, in vivo experimental loading regimes with increasing peak loads as healing progressed (Aranzulla et al, 1998;Duda et al, 1998). The initial magnitude of the load was 100 N, but was then adapted in a biofeedback-loop, as a function of the interfragmentary movement in the previous iteration.…”

“…9 Additional well aligned outcomes were described in early work by Aranzulla, whereby a single patient with a severe OTF was shown to experience a plateau in preferred walking speed at 30-weeks, with continued improvement in walking quality through 48-weeks and beyond. 10 Revised manuscript Jan '15…”

“…Aranzulla implemented a portable yet cumbersome gait analysis apparatus in 3 patients with tibial fractures. 10 One of those patients with a severe open tibial fracture exhibited a plateau in walking speed at 30-Revised manuscript Jan '15 weeks (6-months) and improved quality of gait (weight bearing) at 48-weeks (12-months) post-operatively. Unfortunately sample size limitations prevent much from being established aside from the feasibility of such assessment methodology.…”

The aim of this study was to quantify and characterise the return of functional mobility following open tibial fracture (OTF) using the Hamlyn Mobility Score (HMS). Twenty patients who had undergone post-traumatic lower limb reconstruction were followed up at 3-month intervals for 1-year. An ear-worn motion sensor (e-AR, Imperial College London) was used to assess the performance of subjects during a short activity protocol. The HMS and its constituent kinematic features were calculated longitudinally, allowing mobility analysis throughout recovery as well as between subjects with varying severity of injury. Functional mobility of the cohort improved throughout the full follow-up period. Patients with more severe fractures appeared to recover at a slower rate, with Gustilo-1 (G1) completing the majority of their recovery within the first 3-months, G2 until 6-months, G3 patients until 9-months. Gait analysis revealed walking quality continues to improve 12-months postoperatively, whereas walking capacity plateaus after 6-months. Late complications were detected where subject recovery trajectories deviated >0.5 SD below that of the cohort. This is the first objective, longitudinal assessment of functional recovery in the OTF cohort, providing multidimensional evidence which begins to clarify the differences in prognosis associated with fracture severity. 4Revised manuscript Jan '15

“…In particular, orthopedic patients with uncemented total hip arthroplasty, fracture, or osteotomy are often instructed to bear partial weight on their injured or postoperative lower limb4,5,6,7 ) . The common level of partial weight bearing training prescribed by the orthopedic surgeon ranges from 20% to 50% of the patient’s entire body weight8 ) .…”

Comparison of the Plantar Pressure Distributions at Different Degrees of Tilting: A Preliminary Report

[Purpose] The purpose of this study was to investigate the amount of plantar pressures on the lower limb during tilt table standing and to indicate the ideal degree of tilting for partial weight bearing. [Subjects and Methods] Fifteen healthy subjects between the ages of 20 and 30 were recruited as volunteers for this study. All the measurements were taken while standing on a tilt table according to different inclination angles. [Results] The plantar pressures for 60° tilt table standing were lower by 7–9% of total body weight than the pressures during tilt table standing at 90°, and the pressures for 30° tilt table standing were lower by 18–20% of total body weight than the pressures for tilt table standing at 90°. [Conclusion] Standing training on a 60° tilt table might be equivalent to 80% of full weight bearing training, and tilt table standing training at 30° might be equivalent to 60% of full weight bearing training.
