    Hi guys! Does anyone know the answer to this question?

    Describe and discuss the factors affecting the ground reaction forces in the vertical, anteroposterior and mediolateral directions of customary speed walking. Highlight what features of the force-time graphs are typically assessed to quantify aspects of an individual's gait, and give examples of how such features might differ e.g between different patient groups, different walking conditions/styles, or due to injury or gait abnormality.

    Thanks!

    Well, it's an essay question so it's rather difficult to give you "the" answer.

    Break the question down into chunks and answer what you can by yourself, and then we can push you further in the right direction:

    Describe factors affecting GRF in x, y, z axes:
    -what stuff affects how much force your feet are transmitting to the ground? Why might a 110kg rugby player have different GRFs than a 50kg gymnast?

    Force-time graphs in gait:
    -It's asking you what parts of force-time graphs give you information you can gleam from a graph of these two variables against each other. What can you tell about how the force changes over time - cadence is an obvious one that jumps out. What about other biomechanical variables? Like postural stability/sway? What features in graphs give you information on these?

    How would force-time graphs differ in different populations:
    -What does the graph look like in someone with a normal gait vs an ACL tear? Any differences with heel strike vs forefoot strike? Conditions like Parkinson's or stroke?
