Root theory: With Dr. Root’s classification of a “normal” foot in mind, We choose to discuss 3 of the 8 criteria of normalacy could be applied to the case study. 1) While it was difficult to observe (due to long pants), the client appeared to be knock-kneed or genu valgum, thus the bisection of the distal third of her lower limb is was not vertical. 2) During midstance she could not maintain neutral position. 3) Finally there rotational influences from the lower limbs present, which affected the position of her foot. These are most likely due to hip muscular imbalances and/or weaknesses (Daniel & Colda, 2012).
Stress theory: Concepts from this theory can be applied to the client’s areas of OA. Reducing friction between bone/cartilage within the knee joint, midfoot, and patella tracking is paramount for relief. In additional, cushion can be implemented to reduce forces where fat pad atrophy has occurred.
Sagittal Plane theory: A study by Baliunas et al. (2002), discovered that subjects with OA had a tendency to have a greater than normal peak external knee adduction moment. Clearly this deviation of knee alignment in the sagittal plane has caused there to be extra stress on the medial compartment of the knee which can lead to knee osteoarthritis. …show more content…
While observing the client 's biomechanics is was noted that there may be patella articulation issues. If the patella is not tracking properly within the “groove” of the femoral trochlea, patellofemoral pain syndrome (PFPS) may be cause her symptoms (Servi, 2009). A literature review conducted by Prins and Van Der Wurff discovered that females with weak hip musculature (extensors, abductors, and external rotators) are prone to develop PFPS (Prins & Van Der Wurff, 2009), the client’s gait analysis displayed signs of hip muscular
