Background: Patients whohave knee instability that isassociated with neuromuscular disease(NMD) and
central nervous system (CNS) conditions can betreated using orthoses, suchas knee–ankle–foot
orthoses (KAFOs).
Objectives: To assess existing evidence on the effectiveness of orthoses; patient perspectives;
types of orthotic devicesprescribed in the UK NHS; and associated costs.
Methods: Qualitative study of views of orthoses users –aqualitative in-depth interview study was
undertaken. Data were analysed for thematic content. A coding scheme was developed andan inductive
approach was used to identify themes. Systematic review – 18databases were searched up to November
2014: MEDLINE, MEDLINE In-Process &Other Non-Indexed Citations, Cumulative Index to Nursing and
Allied Health, EMBASE, PASCAL, Scopus, Science Citation Index, BIOSIS Previews, Physiotherapy Evidence
Database, RecalLegacy, Cochrane Database of Systematic Reviews, Databaseof Abstracts of Reviews of
Effects, Health Technology Assessment database, Cochrane Central Register of Controlled Trials,
Conference Proceedings Citation Index: Science, Health Management Consortium, ClinicalTrials.gov,
International Clinical Trials Registry Platform and NationalTechnical Information Service. Studies of adults
using anorthosis for instability of theknee related to NMD or aCNS disorder were included. Data were
extracted and quality was assessed by two researchers. Narrative synthesis was undertaken. Survey and
costing analysis –aweb surveyof orthotists, physiotherapists and rehabilitation medicine physicians was
undertaken. Telephone interviews with orthotists informed acosting analysis.

ABSTRACT
Results: Qualitative study –atotal of 24 people participated. Potential for engagement indaily activities
was of vital importance to patients; theextent to which their deviceenabled thiswas the yardstick by
which itwas measured. Patients’prime desiredoutcome was areduction in pain, falls or trips, with
improved balance and stability. Effectiveness, reliability, comfort and durability were themost valued
features of orthoses. Many expressed frustration with perceived deficiencies in service provision relating to
appointment and administrative systems andreferral pathways. Systematic review –atotal of 21 studies
(478 participants) were included of people who had post-poliosyndrome, inclusion bodymyositis, were
post strokeor had spinal cordinjury. The studies evaluated KAFOs (mainly carbon fibre), stance control
KAFO and hipKAFOs. All of the studies were at risk of bias and, in general, were poorlyreported. Survey
and costing analysis –in total, 238 health-care professionals responded. Arange of orthoses isprescribed
for knee instability that is related to NMD or CNS conditions, approximately half being custom-made.
At least 50% of respondents thought that comfort and confidence inmobility were extremely important
treatment outcomes. The cost of individual KAFOs was highly variable, ranging from £73 to £3553.
Conclusions: Various types of orthoses are used inthe NHS to manage patients with NMD/CNS conditions
and knee instability, both custom-made and prefabricated, of variable cost. Evidence onthe effectiveness
of theorthoses is limited, especially in relation to theoutcomes that are important to orthoses users.
Limitations: The population includedwas broad, limiting anyin-depth consideration of specific conditions.
The response rate to thesurvey was low, and thecosting analysis was based on someassumptions that
may notreflect the true costs of providing KAFOs.
Future work: Future work should include high-quality research on the effectiveness and cost-effectiveness
of orthoses;development of acoreset of outcome measures; further exploration of theviews and
experiences of patients; and thebest models of service delivery.
Study registration: This study isregistered as PROSPERO CRD42014010180. The qualitative study is
registered as Current Controlled Trials ISRCTN65240228.
Funding: TheNational Institute for Health Research HealthTechnology Assessment programme.
