Hydrotherapy in the Rehabilitation of Lower Limb Stress Fractures
Stress fractures can occur anywhere but manifest predominately in the lower limbs particularly the tibia. Other anatomical sites include the fibula, metatarsals, navicular, calcaneus, femur, patella, pars interarticularis, and ribs. The precise pathophysiology has not been clearly defined but appears related to mechanical overload. If the applied stress stimulates excessive bone resorption in relation to formation then micro-factures may result. Such altered stresses may result from repetitive compression; torsion, ligament tension, muscle hyperactivity or muscle fatigue impairing force attenuation. There may also be intrinsic contributing factors previously discussed. The fundamental principle of rehabilitation is progressive, pain-free activity.
Some Hydrotherapy techniques for stress fracture therapy:
o 'Conventional' method and Bad Ragaz patterns for joints above and below the fracture site and hydrodynamic exercise.
o Progression from buoyancy assisted to buoyancy resisted exercise with alterations of lever length.
o Bad Ragaz patterns, from isometric to isotonic and increasing amounts of turbulence appropriately placed around the athlete in while in sitting and standing orientations will stimulate muscle activity as well as balance mechanisms.
