Development and 5-year Evaluation of Diagnosis-Specific Protocols for Visual Neuro-Rehabilitation in a Multicenter Inpatient Rehabilitation Network.

Objective: To provide a retrospective evaluation of a new eye and vision rehabilitation care pathway in a U.S. multi-site inpatient rehabilitation network involving the occupational therapy (OT) staff and a consulting doctor of optometry (OD) specializing in vision rehabilitation. Design: Retrospective study. Setting: Two Inpatient Rehabilitation Facilities (IRFs) and 1 Long Term Acute Care Hospital (LTACH). Participants: There were 2083 records reviewed (44% women, avg. age 59 years). The most common diagnoses were hemispatial neglect (19.2%), homonymous field defects (18.5%), and oculomotor cranial nerve palsies (16.7%) (N=2083). Interventions: Clinical care was reviewed where diagnosis-specific protocols were developed and training was provided to OTs in order to reinforce OD-prescribed interventions during daily treatment sessions, including (1) third, fourth, and sixth ocular cranial nerve palsies (OCNPs) with prisms fitted for full time, postural adaptation training, and oculomotor re-education using pursuits, saccades, head-rotations, and binocular vision exercises including alternate cover and vergence; (2) homonymous hemianopia with training awareness of field loss, eccentric viewing, and fitting of Peli lens for optical field expansion; and (3) prism adaptation therapy (PAT) for left hemispatial neglect. Main Outcome Measures: Frequency of diagnoses. Hypothesis: Diagnoses with developed protocols were most common. Secondarily, feasibility and efficacy by anonymous OT survey. Results: 2083 vision consults were performed over 5 years. The most common diagnoses were hemispatial neglect (n=399, 19.2%), homonymous field defects (n=386, 18.5%), and OCNPs (n=347, 16.7%). None of the OTs reported the protocols were infeasible and 63% (IQR 38%-69%) reported their patients benefited from the interventions. The survey suggested prism for OCNPs helped in 42%, and Peli lens and PAT both helped in 38%. Conclusions: Data support the feasibility of this inpatient eye and vision rehabilitation care pathway which may be used as a foundation for creating or refining similar programs elsewhere. Uniform administration of IRF-based visual neuro-rehabilitation care could provide a substrate for future clinical trials to evaluate efficacy.

Psychometric properties of light touch-pressure somatosensory measures in adults with neurological disorders: A systematic review.

OBJECTIVES: To critically appraise the psychometric properties of light touch-pressure somatosensory assessments to provide guidance for tool selection for research or clinical purposes. DATA SOURCES: MEDLINE, CINAHL, and PsycInfo were searched for research indexed from January 1990-November 2022. English language and human subject filters were applied. "Somatosensation", "psychometric property", and "nervous system-based health condition" search terms were combined. Grey literature and manual searches were conducted to ensure thoroughness. REVIEW METHODS: The reliability, construct validity, and/or measurement error of light touch-pressure assessments was reviewed in adult populations with neurological disorders. Reviewers individually extracted and managed data including patient demographics, assessment characteristics, statistical methods, and psychometric properties. Methodological quality of results was evaluated using an adapted version of the COnsensus-based Standards for the selection of health Measurement INstruments checklist. RESULTS: Thirty-three of 1938 articles were included for review. Fifteen light touch-pressure assessments demonstrated good or excellent reliability. Further, five of those 15 assessments achieved adequate validity and one of the 15 assessments achieved adequate measurement error. Over 80% of the summarized study ratings were determined to be of low or very low quality. CONCLUSION: We recommend using electrical perceptual tests, the Semmes-Weinstein Monofilaments, the Graded and Redefined Assessment of Strength, Sensibility, and Prehension, and the Moving Touch Pressure Test given that they demonstrated good to excellent results in three psychometric properties. No other assessment achieved adequate ratings in more than two psychometric properties. This review highlights a fundamental need to develop sensory assessments that are reliable, valid, and sensitive to change.

Inpatient Virtual Vision Clinic Improves Access to Vision Rehabilitation Before and During the COVID-19 Pandemic.

OBJECTIVE: To describe and evaluate a secure video call system combined with a suite of iPad vision testing apps to improve access to vision rehabilitation assessment for inpatients. DESIGN: Retrospective. SETTING: Two acute care inpatient rehabilitation hospitals and 1 long-term acute care (LTAC) hospital. PARTICIPANTS: Records of inpatients seen by the vision service. INTERVENTIONS: Records from a 1-year telemedicine pilot performed at acute rehabilitation (AR) hospital 1 and then expanded to AR hospital 2 and LTAC hospital during coronavirus disease 2019 (COVID-19) were reviewed. In the virtual visits, an occupational therapist measured the patients' vision with the iPad applications and forwarded results to the off-site Doctor of Optometry (OD) for review prior to a video visit. The OD provided diagnosis and education, press-on prism application supervision, strategies and modifications, and follow-up recommendations. Providers completed the telehealth usability questionnaire (10-point scale). MAIN OUTCOME MEASURES: Vision examinations per month at AR hospital 1 before and with telemedicine. RESULTS: With telemedicine at AR hospital 1, mean visits per month significantly increased from 10.7±5 to 14.9±5 (P=.002). Prism was trialed in 40% of cases of which 83% were successful, similar to previously reported in-person success rates. COVID-19 caused only a marginal decrease in visits per month (P=.08) at AR1, whereas the site without an established program (AR hospital 2) had a 3-4 week gap in care while the program was initiated. Cases at the LTAC hospital tended to be more complex and difficult to manage virtually. The telehealth usability questionnaire median category scores were 7 for Ease of Use, 8 for Interface Quality, 6 for Reliability, and 9 for Satisfaction and Future Use. CONCLUSIONS: The virtual vision clinic process improved inpatient access to eye and visual neurorehabilitation assessment before and during the COVID-19 quarantine and was well accepted by providers and patients.
