A COMPARISON OF TRUNK EXTENSOR STRENGTH AND SQUAT LIFTING ABILITY

Back testing devices are frequently utilized in the clinic to assess f unction and return to work readiness in place of the job task, yet lit tle research on their validity has been reported. This study was condu cted to determine ii correlations exist between squat lilting and isoi nertial and isometric trunk extensor strength, torso length and isoine rtial and isometric trunk extensor strength, and body weight and isoin ertial and isometric trunk extensor strength. Twenty-eight subjects pa rticipated in two sessions involving B200 testing and 30.5 cm to knuck le lifting ability. Regression and correlations were performed The res ults indicate that body weight and torso length do not demonstrate a r elationship with trunk extensor strength, and isometric and isoinertia l trunk extensor strength cannot be used accurately to estimate one's 30.5 cm to knuckle lifting ability. In conclusion, other anthropometri c measures should be investigated ii anthropometrics are used to estim ate strength, and functional testing should be used to evaluate functi on.
