Decline in Lumbar Extensor Muscle Strength in Older Adults
Decline in Lumbar Extensor Muscle Strength in Older Adults
In conclusion, significant correlations were found between age, thoracic kyphosis and fibre angles of the lumbar muscles and lumbar muscle strength; fibre angles of the lumbar extensors muscles with their strength. However, only age and gender appeared in the regression analysis in older adults. In the regression equation for younger adults, gender was the only predictor for lumbar extensor muscles. These results suggest that the decline in the lumbar extensor muscle strength might depend on different factors across the ages and different models are required for older adults.
Quantitative assessment of lumbar extensor muscle strength in older adults can be difficult and may be influenced by many factors. The regression analysis equation in the study could become a useful clinical tool after it has been refined through gathering of more normative data to predict lumbar extensor muscles strength, in situations where direct measurement of muscle strength would be inappropriate. This regression equation can also be used to compare normative data with the clinical population such as low back pain, osteoporosis and spinal deformities. Thus, it provides an estimate for the clinical judgment of the amount of lumbar extensor muscle deficit present.
