Physical tests offer uncertain forecasts for low back pain
A review found limited support for predicting later back-pain outcomes from strength, endurance or flexibility tests. The evidence was generally weak.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
This review asked whether physical test results could predict later outcomes in adults with low back pain. Several measures showed no predictive ability or inconsistent results, but the evidence was too weak for firm conclusions about their usefulness. The question was prognosis: the review did not test whether exercise or other treatments improve back pain.
This abstract-based account reflects evidence weakened by imprecise estimates, studies at high risk of bias and insufficient control of other influencing factors. The abstract also does not define the exact follow-up intervals or favorable outcomes.
Some tests lacked predictive support
Low-quality evidence suggested that higher back-extension endurance, stronger handgrip and higher fingertip-to-floor test results did not predict favorable long-term outcomes. Because certainty was low, this should not be read as definitive proof that these measures have no predictive value.
Other signals remain tentative
Results for lumbar extension, straight-leg raise and back-flexion endurance were inconsistent. Some measures in studies that could not be combined appeared promising, but the review did not establish them as reliable predictors of later outcomes.
