Multiple Imputation for Nonresponse in Surveys

As people get older, they may fall more often for a variety of reasons including problems with balance, poor vision, and dementia. Up to 30% may fall in a year. Although one in five falls may require medical attention, less than one in 10 results in a fracture.
This review looked at the healthcare literature to establish which fall prevention interventions are effective for older people living in the community, and included 159 randomised controlled trials with 79,193 participants.  
Group and home-based exercise programmes, usually containing some balance and strength training exercises, effectively reduced falls, as did Tai Chi. Overall, exercise programmes aimed at reducing falls appear to reduce fractures.
Multifactorial interventions assess an individual's risk of falling, and then carry out treatment or arrange referrals to reduce the identified risks. Overall, current evidence shows that this type of intervention reduces the number of falls in older people living in the community but not the number of people falling during follow-up. These are complex interventions, and their effectiveness may be dependent on factors yet to be determined.  
Interventions to improve home safety appear to be effective, especially in people at higher risk of falling and when carried out by occupational therapists. An anti-slip shoe device worn in icy conditions can also reduce falls.
Taking vitamin D supplements does not appear to reduce falls in most community-dwelling older people, but may do so in those who have lower vitamin D levels in the blood before treatment.  
Some medications increase the risk of falling. Three trials in this review failed to reduce the number of falls by reviewing and adjusting medications. A fourth trial involving family physicians and their patients in medication review was effective in reducing falls. Gradual withdrawal of a particular type of drug for improving sleep, reducing anxiety, and treating depression (psychotropic medication) has been shown to reduce falls.
Cataract surgery reduces falls in women having the operation on the first affected eye. Insertion of a pacemaker can reduce falls in people with frequent falls associated with carotid sinus hypersensitivity, a condition which causes sudden changes in heart rate and blood pressure.
In people with disabling foot pain, the addition of footwear assessment, customised insoles, and foot and ankle exercises to regular podiatry reduced the number of falls but not the number of people falling.
The evidence relating to the provision of educational materials alone for preventing falls is inconclusive.

The Pharmacological Basis of Therapeutics

First metatarsophalangeal (MTP) joint osteoarthritis (OA) is a common and painful problem that causes significant disability. There is limited research on assessment and treatment options, and the efficacy of current management strategies is unknown. The aim of this study was to determine how podiatrists and physical therapists in Australia and the United Kingdom (UK) manage people with first MTP joint OA. A survey of podiatrists and physiotherapists was conducted. Potential respondents were recruited through professional representative organisations in Australia and the UK. Participants completed a bespoke online survey regarding the assessment and treatment approaches they most commonly use for patients with first MTP joint OA. Descriptive statistics were calculated and differences between professions compared using chi-square. Two hundred respondents (n = 113 (57%) podiatrists and n = 140 (70%) from Australia) completed the survey. Assessment tests were similar between professions and included x-ray (n = 151/164; 92%), range of motion (n = 127/141; 90%), and a pain scale (n = 78/99; 79%). Podiatrists were more likely than physical therapists to discuss over-the-counter medication (42% vs 17%; p < 0.001), prescribe orthoses (97% vs 66%; p < 0.001), particularly custom orthoses (78% vs 42%; p < 0.001), and provide advice on footwear (92% vs 78%; p < 0.01) when treating first MTP joint OA. In contrast, physical therapists used more exercise-based approaches to treatment, including exercise therapy (91% vs 34%; p < 0.001), increasing general activity (70% vs 49%; p < 0.01), and advice to pace activities (83% vs 48%; p < 0.001). Podiatrists and physical therapists use an array of assessment and treatment approaches for people with first MTP joint OA, albeit there is limited evidence to support their clinical utility. Treatment strategies differ between professions, particularly with respect to medication, orthoses and exercise. It is unclear whether these commonly-used strategies improve symptoms associated with first MTP joint OA.

Falls in Older People: Environmental risk factors for falls

Despite research supporting its validity in predicting falls, simple reaction time (SRT) is not typically included in a clinical falls assessment battery because there is no standardised, clinically feasible testing protocol with published cutoff scores. This study aimed to determine whether SRT scores obtained using a clinically viable protocol could discriminate between multiple and single fallers. SRT scores were obtained from 147 participants (88 women and 59 men) over the age of 65 years (mean 80.1 years; SD 8.4 years) who had reported one or more falls in the previous 12 months. Forty-eight single and 99 multiple fallers were recruited from the subacute public hospital sector. SRT scores significantly discriminated between faller groups (Wilk's λ = 0.89, p = 0.05), with SRT score being the dominating predictor between groups. A receiver operating characteristic (ROC) curve showed good diagnostic accuracy with the area under curve = 0.78. A cutoff score of 394.5 ms provided the best balance between s...

Objective. Abnormal foot posture and function have been proposed as possible risk factors for low back pain, but this has not been examined in detail. The objective of this study was to explore the associations of foot posture and foot function with low back pain in 1930 members of the Framingham Study (2002–05).

Methods. Low back pain, aching or stiffness on most days was documented on a body chart. Foot posture was categorized as normal, planus or cavus using static weight-bearing measurements of the arch index. Foot function was categorized as normal, pronated or supinated using the centre of pressure excursion index derived from dynamic foot pressure measurements. Sex-specific multivariate logistic regression models were used to examine the associations of foot posture, foot function and asymmetry with low back pain, adjusting for confounding variables.

Results. Foot posture showed no association with low back pain. However, pronated foot function was associated with low back pain in women [odds ratio (OR) = 1.51, 95% CI 1.1, 2.07, P = 0.011] and this remained significant after adjusting for age, weight, smoking and depressive symptoms (OR = 1.48, 95% CI 1.07, 2.05, P = 0.018).

Conclusion. These findings suggest that pronated foot function may contribute to low back symptoms in women. Interventions that modify foot function, such as orthoses, may therefore have a role in the prevention and treatment of low back pain.

Foot posture, foot function and low back pain: the Framingham Foot Study

First metatarsophalangeal (MTP) joint osteoarthritis (OA) is a painful and debilitating condition affecting nearly one in 10 people aged over 50 years. Non-drug, non-surgical treatments are recommended by OA clinical guidelines, yet there have only ever been two randomised controlled trials (RCTs) evaluating such strategies in people with first MTP joint OA. Foot orthoses are a common non-drug, non-surgical strategy used by allied health professionals for people with first MTP joint OA, however, it is unknown whether these devices are effective in improving the symptoms associated with the condition. This clinical trial aimed to determine whether contoured foot orthoses lead to greater reductions in first MTP joint pain on walking compared to sham flat insoles in people with first MTP joint OA. The FORT trial (Foot ORthoses for big Toe joint osteoarthritis) is a two-arm participant- and assessor-blinded, multi-site RCT conducted in Melbourne, Sydney, Brisbane and the Gold Coast, Australia. We are recruiting 88 community-dwelling people with symptomatic radiographic first MTP joint OA. Following baseline assessment, participants are randomized to receive either: i) contoured foot orthoses; or ii) sham flat insoles following baseline assessment. Participants have two visits with a study podiatrist where they are provided with their allocated insoles, to be worn daily for 12 weeks at all times when wearing shoes. The primary outcome is self-reported first MTP joint pain on walking (numerical rating scale), assessed at baseline and 12 weeks. Secondary outcomes include additional measures of first MTP joint and foot pain, physical function, quality of life, participant-perceived global ratings of change (pain and function), and level of physical activity. This study will provide novel evidence about whether contoured foot orthoses improve pain and other symptoms compared to sham insoles in people with first MTP joint OA. Outcomes will help to inform clinical guidelines and practice about the use of foot orthoses for managing symptoms in this under-researched group of people with OA.
