However, some patients present with positional symptoms compatible with BPPV yet show no observable nystagmus on the DHT. We introduced the Head Rotation Sit-up Test (HRST) as a symptom-based maneuver and hypothesized that it would identify DHT-negative patients who nonetheless benefit from canalith repositioning. This study aimed to explore the potential role of the HRST. It was introduced as a complementary, symptom-based maneuver for evaluating non-classical vertigo presentations. Materials and Methods: We retrospectively reviewed patients clinically suspected of having BPPV by the attending physicians at Nara Medical University Hospital (August 2018\u2013July 2022). All underwent both the DHT and HRST; those positive on either test received the Epley maneuver and were included. Patients were categorized as Group 1: DHT(\u2212)\/HRST(+), and Group 2: DHT(+), irrespective of the HRST, for the purpose of comparing patients who were positive on the HRST with those positive on the DHT. Post-treatment symptom severity was assessed on a 0\u201310 scale, with the patient\u2019s most severe pre-treatment symptom defined as 10, and responder rates (post-Epley score &lt; 5) were compared. Results: Among 179 patients with suspected BPPV, 80 were test-positive and were treated with the Epley maneuver. Group 1 comprised 31 patients, who more commonly reported non-rotational symptoms such as floating or unsteadiness, whereas rotational vertigo predominated in Group 2 (n = 49). Median post-Epley scores were significantly lower after treatment in both groups (Group 1: 2 [IQR 0\u20133]; Group 2: 3 [IQR 0\u20135]). Group 1 demonstrated a higher responder rate than Group 2 (90.3% vs. 65.3%, p = 0.016). Within Group 2, outcomes did not differ significantly between DHT(+)\/HRST(+) and DHT(+)\/HRST(\u2212) subgroups. Conclusions: The HRST identified a clinically relevant subgroup of DHT-negative patients who nevertheless responded favorably to the Epley maneuver. Incorporating the HRST alongside the DHT may expand the diagnostic reach for BPPV, particularly among patients with non-classical symptoms or without observable nystagmus. These findings support the HRST as a useful complementary maneuver for detecting Epley responsive, symptom based positional vertigo.<\/jats:p>","DOI":"10.3390\/medicina62010217","type":"journal-article","created":{"date-parts":[[2026,1,20]],"date-time":"2026-01-20T15:18:32Z","timestamp":1768922312000},"page":"217","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Exploring
