Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Ease of walking, as assessed by Timed up and Go test (3 metre) (timed, as well as qualitative comments on gait initiation, speed and safety on turning), on 3 different floor surfaces. These include at least 2 low impact flooring systems and 1 control (standard vinyl on subflooring of concrete).
The 3 low impact floor systems to be tested are (1) Smart Cell flooring which is a standard vinyl laid on a low impact subflooring approx 15mm deep (2) Omnisport Excell floor which is 8-10mm thick and has the vinyl combined with the softer subflooring and is laid as one surface (3) Kradal floor tiles which are again a combined product of vinyl fused with with the low impact layer.
Each patient will be observed twice on each floor type
Patients will be Parkinson's patients or stroke patients and a control group of older rehabilitation patients already in hospital, but who do not have Parkinson's or stroke

Eligibility
Key inclusion criteria
Current inpatients from any of 5 Older Persons health inpatient wards will be recruited aiming to select a convenience sample that includes: Parkinson’s patients (N=20), Stroke patients with either motor deficits such as hemiplegia with foot drop, poor foot clearance or proprioceptive loss (N= 20) and Control group-non stroke and non-Parkinson’s (N=20)
Minimum age
65 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Patients need be mobile with or without a walking aid (can be with one person assistance) to be included. Those less mobile, such as those requiring 2 people for walking or hoist transfers are excluded, but could be included later when their mobility has improved.

Study design
Purpose of the study
Prevention
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Convenience sample of current inpatients who have either Parkinson's disease or Stroke (both groups postulated to have greater difficulty walking on low impact flooring.
The order of allocation to each floor type will be randomised.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation for the order which floor type tested (random number table from statistics book)
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Single group
Other design features
Each patient will be video recorded during their walking tests. These will be assessed by at least 2 different observers (unable to be blinded due to floor surfaces appear different)
Phase
Not Applicable
Type of endpoint/s
Safety
Statistical methods / analysis
Exploratory study only to see whether anecdotal comments about Parkinson's patients on these low impact floors are real or not
Between group (PD vs Stroke vs control) and between floor type (low impact floor 1 vs low impact floor 2 vs control floor) comparisons. Both quantative (timed TUG) and qualitative assessment of gait will be compared.
TUG times will be compared using students T test (if normal) or Non parametric (such as MWU) if not normal distribution.
Visual analague scores for patient subjective views on comfort and stability whilst walking on these floors will be compared with students t-tests or non paramaetric if data not normal distribution

Summary
Brief summary
Falls in hospital are common. Between 35-42% of falls cause injuries and 1 – 3% result in a fracture. These fractures are usually hip or pelvis fractures which threaten life and/or independence. Whilst there are some effective fall prevention strategies for falls in hospitals, fall rates and fall related injuries remain high. It is generally not possible to predict which falls or patients will have injurious falls. One approach is to tackle the whole population at risk by using energy absorbing or low impact flooring (LIF) to prevent injury.

One trial to investigate the practical aspects LIF has already been completed and another is ongoing investigating falls and fall related injuries. For both, 3 different LIFs have been laid in one ward at PMH (total of 12 bed spaces) whilst 8 bed spaces have standard vinyl flooring (SF). During the trial, staff noted that 1 Parkinson’s patient appeared to have more gait initiation difficulties on the LIF. Parkinson’s patients often have gait initiation problems. Staff have commented that some other patients were thought to have “sticky feet” on LIF.
Softer surfaces (includes carpets or LIF), could potentially worsen gait in patients with existing poor balance (eg Parkinson’s and stroke patients). Thus the aim of this exploratory study is to examine gait characteristics on LIFs compared to SF in different patient diagnostic groups.
