Aconcagua is the highest peak in South America and the Southern hemisphere. My husband Stan and I have enjoyed climbing many mountains and decided to tackle Aconcagua, without a guide.

Testing of Lumbar Function If the identification and resulting prevention of the incidence of low back disorders is to become a real possibility, meaningful testing of the lumbar muscles must be produced. Testing must not only include the measurement of the specific strength of these muscles but their range of motion and their “typing” with [...]

For the sake of retaining reasonable length to this article it must be sufficient to state that the lumbar region of the human spine is subject to enormous and continuous mechanical forces which create an increased likelihood of potential injury.

According to Hollingsworth and Watson, age is moderately correlated with performance on the Depression scale of MMPI and sex is negatively correlated with performance on the Hysteria scale of the MMPI. According to the multiple regression analysis utilized, no interrelationships of particular strength or significance was found with regard to the set of predictor variables.

Preventive Training Approaches Since the majority of low back traumas occur as a result of an acute or chronic exposition of the musculo-skeletal system to forces which supersede the momentary potential of the affected anatomical region, it makes very good sense to condition those historically vulnerable areas.

The incidence of low back disorders in the U. S. has been substantially documented in the literature and described as epidemic in magnitude. The cost of low back related treatment and disability has been estimated at approximately ten billion dollars annually.
