| Outline of Final Research Achievements |
To enhance the safety and detection sensitivity of an experimental hammering system developed for identifying lumbar spondylolysis, we redesigned and newly developed the system. The newly developed acoustic-vibration diagnostic system employs wavelet time-frequency analysis as its signal processing method, allowing for the detection of signals propagating exclusively within the bone. Evaluation using an artificial bone model demonstrated a significant reduction in signal power in spondylolysis cases compared to normal cases. Furthermore, when the system was applied to patients with lumbar spondylolysis, results consistent with those obtained from the artificial bone model were observed. These findings suggest that the acoustic-vibration diagnostic system possesses sufficient detection sensitivity for application to living subjects.

腰椎分離症はスポーツ傷害の一種であるが、主たる症状となる腰痛は初期においてスポーツ活動の高い運動量となる一瞬である。このため多くのスポーツ選手は、症状の増悪する進行期まで医療機関を受診することは少ない。腰椎分離症は進行に伴い、分離部の癒合の割合が減少するため、残存した腰椎分離症は成人期には腰痛が慢性化するだけでなく腰椎分離辷症へと進行し重度化する可能性がある。したがって、早期に腰椎分離症を発見し癒合を期待することができれば成人期に腰痛による社会的生産性を減弱することを抑制することが可能となる。
