This study employed a single-blind, randomized controlled trial design involving participants aged 11\u201330 years within 10 days of a concussion. Participants with receded NPC (i.e., mean NPC \u22655 cm) were randomized to either BSVT or UC. The BSVT group was prescribed BSVT exercises (5 reps, 2\u00d7 daily, using \u223c3 meters string with three colored beads). The UC group was prescribed symptom-specific management strategies (i.e., breaks during reading or other visual tasks) and behavioral management (e.g., sleep, hydration, diet) until follow-up (7\u201314 days post-enrollment). Two-way mixed effects analyses of variance examined the interaction between group (BSVT, UC) and time (enrollment, follow-up) on mean NPC (primary outcome) and secondary outcomes (e.g., Concussion Clinical Profile Screen [CP Screen]). Fifty participants were enrolled, with 25 in BSVT (age = 15.8\u2009\u00b1\u20094.1, 44% F, 84% sport-related concussion [SRC]) and 25 in UC (age = 17.9\u2009\u00b1\u20094.8, 36% F, 60% SRC). Results supported an interaction in the BSVT group for NPC (F[1, 48] = 5.3,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = 0.026, \u03b7\n                    <jats:sub>p<\/jats:sub>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.10) and CP Screen Neck (F[1, 43] = 4.9,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = 0.033, \u03b7\n                    <jats:sub>p<\/jats:sub>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.10). The BSVT group exhibited greater improvement in mean NPC distance (\u22128.9 cm, 95% confidence interval [CI] = \u221212.1, \u22125.7,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; 0.001) than the UC group (\u22123.8 cm, 95% CI = \u22126.9, \u22120.6,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = 0.02), and greater improvement in CP Screen Neck symptoms (\u22120.6, 95% CI, \u22121.1, \u22120.03,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = 0.039) than the UC group (0.27, 95% CI, \u22120.3, 0.8,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = 0.32). BSVT improved mean NPC distance compared with UC, suggesting that this simple, inexpensive, and early intervention may be effective for treating receded NPC following concussion.\n                  <\/jats:p>\n                  <jats:sec>\n                    <jats:title>Trial registration:<\/jats:title>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"http:\/\/www.clinicaltrials.gov\">www.clinicaltrials.gov<\/jats:ext-link>\n                      ; identifier: NCT04076657\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/08977151251359960","type":"journal-article","created":{"date-parts":[[2025,9,17]],"date-time":"2025-09-17T01:59:16Z","timestamp":1758074356000},"page":"1708-1718","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Randomized Controlled Trial of Brock String Vision Therapy for Receded Near Point of Convergence Following Concussion"],"prefix":"10.1177","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4539-7120","authenticated-orcid":false,"given":"Alicia M.","family":"Trbovich","sequence":"first","affiliation":[{"name":"UPMC Sports Medicine Concussion Program, Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0663-7320","authenticated-orcid":false,"given":"Aaron J.","family":"Zynda","sequence":"additional","affiliation":[{"name":"UPMC Sports Medicine Concussion Program, Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tori","family":"Togashi","sequence":"additional","affiliation":[{"name":"UPMC Sports Medicine Concussion Program, Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chris","family":"Burley","sequence":"additional","affiliation":[{"name":"UPMC Sports Medicine Concussion Program, Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne","family":"Mucha","sequence":"additional","affiliation":[{"name":"UPMC Rehabilitation Institute, Pittsburgh, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael W.","family":"Collins","sequence":"additional","affiliation":[{"name":"UPMC Sports Medicine Concussion Program, Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony P.","family":"Kontos","sequence":"additional","affiliation":[{"name":"UPMC Sports Medicine Concussion Program, Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,10,6]]},"reference":[{"key":"e_1_3_8_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2023-106898"},{"key":"e_1_3_8_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2023.03.036"},{"key":"e_1_3_8_4_2","doi-asserted-by":"publisher","DOI":"10.1249\/JSR.0000000000000573"},{"key":"e_1_3_8_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546515606430"},{"key":"e_1_3_8_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/JSM.0000000000001102"},{"key":"e_1_3_8_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/0009922815594367"},{"key":"e_1_3_8_8_2","doi-asserted-by":"publisher","DOI":"10.1227\/NEU.0000000000000505"},{"key":"e_1_3_8_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/OPX.0b013e3182772dce"},{"key":"e_1_3_8_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.csm.2010.09.001"},{"key":"e_1_3_8_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbr.2004.06.003"},{"key":"e_1_3_8_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2015.12.010"},{"key":"e_1_3_8_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2019.04.008"},{"key":"e_1_3_8_14_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546514543775"},{"key":"e_1_3_8_15_2","doi-asserted-by":"publisher","DOI":"10.1097\/HTR.0000000000000536"},{"key":"e_1_3_8_16_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546517705640"},{"key":"e_1_3_8_17_2","doi-asserted-by":"publisher","DOI":"10.1080\/02699052.2019.1658131"},{"key":"e_1_3_8_18_2","doi-asserted-by":"publisher","DOI":"10.1123\/jsr.2019-0428"},{"issue":"99","key":"e_1_3_8_19_2","first-page":"52648","article-title":"Vision training methods for sports concussion mitigation and management","volume":"99","author":"Clark JF","year":"2015","unstructured":"Clark JF, , Colosimo A, , Ellis JK, et al.
