Dual Energy X-ray Absorptiometry (DEXA) scan will be used to assess hip bone mineral density (BMD) at femoral head region. Isokinetic PT of hip flexors, extensors, abductors and adductors and knee flexors and extensors will be measured using Biodex System 3 Isokinetic Dynamometer. The measured outcomes will be evaluated at an angular velocity of 60°/sec in a concentric mode of muscle contraction for five successive repetitions. Isokinetic testing will be done at the Isokinetic Laboratory, Faculty of Physical therapy, Cairo University.
