Career Summary

Biography

Senior Physiotherapist in Neurosciences at the John Hunter Hospital and current PhD candidate in the School of Health Sciences. Ryan's PhD  is focusing on improving the accuracy of identifying patients with Idiopathic Normal Pressure Hydrocephalus (iNPH) who would benefit from Neurosurgery.

iNPH is an uncommon condition resulting in walking, memory and continence issues for sufferers which can be treated with a Neurosurgical intervention to drain excessive cerebrospinal fluid which is the characteristic sign of the condition. However not all patients with iNPH will improve from surgery and identify sufferers who improve and who will not is currently challenging. Ryan's study aims to identify tests of walking, balance, memory and fine motor control along with radiological measurements which can better identify and hopefully predict who will benefit from surgery.

This study is being completed at the John Hunter Hospital in Newcastle.

© 2018 Elsevier B.V. Objectives: To determine which cognitive and upper limb assessments can identify change in patients undergoing a Cerebrospinal fluid (CSF) tap test (TT) diagnosed with idiopathic Normal Pressure Hydrocephalus (iNPH). Patients and methods: Prospective observational study of 74 iNPH patients undergoing a CSF TT for consideration of a ventricular peritoneal shunt. Patients who were offered surgical intervention were classified as responders. Patients were assessed with a battery of cognitive and upper limb assessments prior to and following a CSF TT. The Timed up and go cognition (TUG-C), Montreal Cognitive assessment (MoCA) and 9-hole peg test were utilised. Results: 40 patients were classified responders. Significant differences were identified for responders for the MoCA (0.62 points) and TUG-C (-6.02 s). Only the executive function and orientation sub scores of the MoCA showed significant changes for responders. The 9 hole peg test mean change of 4.33 s for responders was not significant. Non-responder change scores for the MoCA (0.22 points), TUG-C (0.3 s) and 9 hole peg test (2.58 s) were not significant. Conclusion: The TUG-C has the potential to identify change in patients resulting from a CSF TT. While statistically significant change was found for the MoCA, a mean change of less than 1 point on this scale is unlikely to be clinically relevant. Similarly, the 9 hole peg test cannot be endorsed as an assessment tool for identifying changed performance in iNPH.

© 2018 American Congress of Rehabilitation Medicine Objectives: To identify in patients with idiopathic normal pressure hydrocephalus (iNPH) undergoing a cerebrospinal fluid (CSF) tap test (TT) for consideration of a ventricular peritoneal (VP) shunt: (1) gait and balance measures, which identify symptom change; (2) differences present between pre¿ and post¿CSF TT scores between patients classified as responders and nonresponder; (3) ability of patients with iNPH to accurately quantify change in their gait and balance symptoms from a CSF TT. Design: Prospective observational study. Post¿CSF TT assessment was completed 2-4 hours post. Setting: Tertiary referral neurological and neurosurgical hospital. Participants: Patients (N=74) with iNPH receiving a 30 mL CSF TT for consideration of a VP shunt. Interventions: Patients underwent a battery of gait and balance measures pre¿ and post¿CSF TT and indicated their perceived change on a global rating of change (GRC). Patients deemed to improve and offered VP shunt insertion by a neurologist or neurosurgeon were labeled responders. Main Outcome Measures: Performance oriented mobility assessment (Tinetti), Berg Balance Scale (BBS), timed Up and Go (TUG), 10-meter walk test (10MWT), GRC. Results: Forty patients were classified responders, 34 nonresponders. Significant differences were identified for responders: Tinetti (3.88 points), TUG (3.98 seconds), 10MWT (0.08 m/sec), and BBS (5.29 points). Significant differences were found for nonresponders for the Tinetti (0.91 points) and BBS (2.06 points). Change scores for responders and nonresponders were significantly different for all tests between responders and nonresponders. GRC scores for gait (+2 for responders, 0 for nonresponders) and balance (+2.5 for responders, 0 for nonresponders) were both significantly different. Conclusions: The Tinetti, BBS, and TUG can identify change in patients undergoing a CSF TT for iNPH. Patients appear to be able to accurately identify if change has occurred.
