Exploring the Feasibility of the Use of Sphygmomanometer for Assessing Hip Abductor Muscle Strength in Avascular Necrosis Patients – A Pilot Study

Abstract

Background Avascular necrosis of the femoral head is a degenerative disorder brought on by a disruption in the blood supply to the subchondral region, which in turn causes the disintegration of cells and eventual destruction of the femoral head. We decided to design a pilot study to see if a sphygmomanometer was an accurate technique to test the muscular strength of the hip abductors considering no research had measured the strength of the abductor muscles beforehand or following surgery.  Methodology The patients were selected based on the conditions for inclusion, and a sphygmomanometer was utilised for assessing each patient's hip abductor muscle strength on three separate occasions. Three times the readings were carried out at these intervals to measure the strength of the abductor muscles in each lower limb. The average value of each of these instances was used to get the final measurement. Subsequently, changes in the mercury's value were noted.  Results According to the findings, the results stated that the feasibility of a sphygmomanometer to assess hip abductors' muscle strength in individuals with femoral head avascular necrosis was formulated.  Conclusion The conclusion of this study demonstrates that the sphygmomanometer is a reliable tool for evaluating hip abductor muscle strength among people with femoral head avascular necrosis.
