Figure 1. 5 year old child had a Ewing's sarcoma of the proximal tibia resected and reconstructed with an allograft. 10 years later the growth in the tibia was maintained |
Video 1. Child walks with a barely imperceptible drop on the right leg |
Figure 2. 14 year old boy had a resection preserving his tibial growth plate for osteosarcoma of the distal femur involving the growth plate |
Video 2. A year later weight bearing is full but he has developed a curious walking stance which appears to be habitual as there is no loss in muscle power clinically |
Figure 3. 14 year old girl had a resection preserving her femoral growth plate for osteosarcoma of the proximal tibia involving the growth plate |
Video 4. 3 years later weight bearing is full and gait is normal |
|
Figure 4. High flexion knee replacement surgery down for arthritis
|
Video 4. 3 months later a mild limp due to hip weakness was readily detected by motion analysis and corrected with simple hip strengthening exercises |
|
Figure 5. Flat footed 12 year old child underwent a subtalar distraction procedure
|
Video 5. 3 months later the flat-footed gait was corrected and subsequently hip and knee deformities seen here normalised |
Video 6.1. The patient underwent anterior cruciate ligament surgery |
Video 6.2. At 6 months it is already difficult to tell which side was operated on |
|
Figure 7. The parametrics provided in the software permit the breakdown of complex movements involved in sporting activity
|
Video 7. The system lends itself well to evaluating the perfect golf swing |
|
Figure 8.1. Martial art movements are specifically difficult to track due to extremely fast movement
|
Video 8. The system has a rapid response rate that is able to track kicking at high speed |
Figure 8.2. In this analysis the point of contact force of both feet were identical however this was achieved through sheer power projection at the right hip and more of a whip action on the left hip. |
