Plantar pressure distribution during walking after specific soft tissue heel injury - Case study

Popis výsledku v původním jazyce

Calcaneal injuries are injuries, affecting the all-aged population. The abnormalities in the gait pattern after calcaneal injuries are very common many months after the injury. These abnormalities can be evaluated by different biomechanical methods. Pedobarography detects differences in plantar pressure distribution between injured (INJ) and uninjured foot (UIN) while walking. The aim of our study was to compare plantar pressure distribution and trajectory of centre of pressure (CoP) in the stance phase during walking 6 and 12 months after the heel injury in a patient after the necrotic tissue removal. This study was a case interpretation. The participant was 9-years old young girl after a car accident. The measurement was performed 6 and 12 months after the injury and after a soft necrotic tissue removal. Measurement of plantar pressure distribution and pressure values was performed while walking on the pedobarography measurement platform (EMED ®-c50/R, Novel, Munich, Germany) with the frequency of 50 Hz. The measurement was done during the stance phase while walking. For each step, loading variables and temporal variables and also trajectory of CoP were observed. The mean of 5 steps for each variable was used to compare INJ and UIN. The loading variables normalized to body mass included peak pressure, representing the maximum pressure recorded under the foot, maximum vertical force and trajectory of CoP. Peak pressure values were higher on the UIN (6 months: 10.4% and 12 months: 8.2%). At maximum vertical force, the values on the UIN were lower (6 months: 3% and 12 months 2.5%). Peak pressure values under the heel were higher on the UIN in both measurements. Six and 12 months after the injury, the trajectory of CoP on the INJ was similar. It started in the midfoot, continued in the direction to the hindfoot and then tended over the metatarsal head to the toes area. Trajectory of CoP in UIN has changed when 6 months after the injury the trajectory was similar to the healthy subjects (starting in the hindfoot and continuing through the midfoot, metatarsal heads to the big toe area) but 12 months after the injury was the trajectory of CoP more similar to the trajectory at the INJ. Plantar pressure distribution asymmetry between the INJ and UIN occurred in both measurements (6 and 12 months follow up). The trajectory of CoP on the UIN in 6 months follow up measurement was similar to the healthy subjects in previous studies but it has changed during the next 6 months. Unfortunately the correct gait stereotype on the UIN has lost and patient tended to use the wrong gait stereotype according the INJ. According to our study we recommend to use orthopaedic insoles with various heel support to eliminate the differences between the plantar pressure distribution under the injured and uninjured foot and to ensure the right gait stereotype.
