Investigation of Possible Use of the Measurement Value of Maximum Expiratory Pressure as Trunk Superficial Flexor Muscle Strength Assessment: Can it be used as Flexor Muscle Strength Assessment in Elderly Persons with Dysspondylism ?

Abstract

The purpose of this study was to investigate the possible use of the measurement value of maximum expiratory pressure(MEP) as trunk superficial flexor muscle strength assessment. Respiratory muscle strength assessment, muscle strength assessment, walking ability assessment, subjective assessment of life views, exercise performance assessment and the number of sit-ups were conducted in 235(male46, female189) home-bound elderly persons. There was significant correlation between MEP and the number of sit-ups. The number of sit-ups, % grip strength, % maximal muscle strength of the quadriceps, toe grasp power, maximal walking speed, timed up and go test, walking time on 10-m hurdle, 6-minute walk distance, active ability were significantly superior in the High-value group of MEP than in the low-value group. Intensity of influencing factor was 1.13 odds ratio on the number of sit-ups. We considered that MEP could inflect as trunk superficial flexor muscle strength assessment.
