A comparison of manual muscle testing and hand-held dynamometry as methods of muscle strength assessment following lumbar spine surgery
摘要
Background: After spine surgery, muscle strength assessment is important for detecting the outcomes and possible complications, such as post-operative spinal epidural hematoma that cause nerve compression. Manual muscle testing (MMT) is one of the most commonly used methods for assessing muscle strength. However, several studies have concluded that MMT fails to differentiate among patients with various degrees of muscle weakness as effectively as more objective methods such as hand-held dynamometry (HHD). Purpose: To determine whether HHD is more sensitive than MMT in patients who have undergone spinal surgery Methods: We used the Hoggan microFET2 dynamometer (Hoggan Scientific, LLC, Salt Lake City, UT, USA) to perform HHD assessments of muscle strength for 82 patients who underwent lumbar spine operations in our hospital from January 2017 to June 2017. We used both HHD and MMT to record the muscle strength of the lower limbs of these patients. Results: A positive relationship between the HHD and MMT results was found, but this relationship was only weak to moderate in strength. The HHD assessments indicated that the average pre-operative to post-operative change in muscle strength was significant. Conclusion: HHD is a sensitive, portable means of force evaluation, and in this study, the HHD results indicated a more significant preoperative to post-operative change in muscle strength than the MMT results. HHD is quick and easy to handle in clinical practice following lumbar spine surgery.
