BackgroundChronic ankle conditions affect approximately 20% of Australian adults. Although there is a plethora of research on chronic hip and knee conditions, there is limited understanding of the impact of ankle problems. Thus, the significance of chronic ankle conditions is not clear. The aim of this study was to compare self-reported function, disability, instability, physical activity and quality of life (QoL) between adults with and without ankle symptoms. A secondary aim was to explore factors associated with QoL.MethodIndividuals with symptoms of ankle pain and stiffness (symptomatic individuals) and controls with no ankle pain or stiffness (asymptomatic individuals) completed a cross-sectional online survey. The survey included the Ankle Osteoarthritis Scale (AOS), Foot and Ankle Ability Measure (FAAM), Cumberland Ankle Instability Tool (CAIT), International Physical Activity Questionnaire (IPAQ), Assessment of QoL (AQoL-6D), and questions about ankle injury history.ResultsA total of 394 individuals (270 symptomatic and 124 asymptomatic) with mean age of 48.8 (standard deviation (SD): 12.1) years and body mass index of 28.7 (7.7) kgm− 2completed the survey. Standardized mean differences (SMD) were large to very large (1.45 to 3.20) for greater disability (AOS) and instability (CAIT), and poorer function (FAAM) in symptomatic compared to asymptomatic individuals. Individuals with ankle symptoms had higher body mass index and lower QoL (medium effect: SMD > 1). There were no differences in self-report physical activity between groups. Lower activities of daily living (ADL) function (FAAM-ADL) best explained QoL in a multiple regression model (R2 = 0.66, p = 0.001).ConclusionIndividuals with ankle symptoms reported ankle instability, greater disability, compromised function and worse QoL compared to asymptomatic individuals. There was a strong relationship between ankle function and QoL. Ankle-specific ability during ADL best explained the reduced QoL in individuals with ankle symptoms. Clinicians and researchers should consider ankle function as an antecedent to poorer QoL in patients who have ankle symptoms.

Background The Australian wine industry is a valuable part of the wider Australian economy worth approximately A$45 billion annually and employs 163,790 people either full time or part time. Australian agricultural industries are amongst the nation’s most dangerous workplaces with joint, ligament, muscle and tendon injuries being commonplace along with wounds, lacerations and musculoskeletal diseases. It is therefore important to try and minimise the risk of injuries to workers. The aims of this study were to (1) identify whether lower limb problems occur in the Australian wine industry and (2) identify the types of safety footwear worn. Methods Participants were recruited from the Australian wine industry. The study was a cross-sectional anonymous survey of 82 questions with n = 207 respondents. Questions related to job role performed, types of lower limb problems experienced, level of pain, restriction of activities, types of footwear worn, general health and physical health. Results The main working roles were winery (73.4%), vineyard (52.2%), laboratory (39.6%), cellar door (32.4%) and office (8.2%), with 63.3% of participants working in more than one role. Lower back pain was the most commonly reported problem at 56% followed by foot pain (36.7%), knee pain (24.6%), leg pain (21.3%), ankle pain (17.9%), hip pain (15.5%), toe pain (13%) and heel pain (11.1%). The most popular footwear used by participants were elastic sided safety boots, followed by high cut lace up safety boots with side zip. Overall, although the pain experienced was moderate, it did not impact the workers ability to perform their duties and the majority self-reported as being in very good general and physical health. Conclusion To date no data have been published on the types of lower limb problems or the types of safety footwear worn in the Australian wine industry. This study is the first to demonstrate that elastic sided safety boots were the most popular amongst respondents and that lower limb problems occur with workers. Therefore, further research into the safety footwear used in the Australian wine industry is needed to better support workers health while working in their varied roles and conditions.

Background While the prevalence and impact of musculoskeletal problems are high, most attention has been directed towards the back, knee and hip disorders. Foot pain is known to be common in older adults and accounts for a significant burden on health services. The aim of this study was to assess the impact of foot and ankle joint pain, considering age, presence of co-morbidities and other site joint pain, in a large community sample. Methods In the North Yorkshire Health study, 16,222 people over 55 years participated in a detailed survey of the prevalence and impact of lower limb joint problems. Self-assessment of overall body pain and functional activities of daily living were assessed. Participants indicated the presence of joint pain, stiffness or swelling during the last 3 months which had lasted for more than 6 weeks on a manikin: data were captured on the foot and the ankle. Results The prevalence of self-reported foot and ankle joint pain was substantial: 184.33 per 1000, second only to knee problems. While foot pain was common, it was mostly associated with joint pain at other sites; only 1 in 11 of those with foot and ankle pain reported it only in the foot. Logistic regression modeling revealed while established factors such as co-morbidities, knee and hip problems contributed to functional impairment, foot and ankle problems contributed to an additional increased risk of having difficulty standing and walking by two fold (OR = 2.314, 95%CI 2.061–2.598), going up and down stairs by 71% (OR = 1.711, 95%CI 1.478–1.980) and getting up from a seated position by 44% (OR = 1.438, 95%CI 1.197–1.729). Conclusion These results suggest that not only are foot problems in the over 55 age group extremely prevalent, they have a considerable impact on functional abilities.

There was an increasing requirement for novel treatments of osteoarthritis (OA). The aim was to compare the efficacy of intraarticular Botulinum toxin type A (BoNT-A) and intraarticular hyaluronate plus rehabilitation exercise in patients with ankle OA. This was a prospective, randomized, assessor-blinded study with a 6-month follow-up period, conducted in the outpatient rehabilitation department at a university-affiliated tertiary care medical center. Seventy-five patients with symptomatic ankle OA (Kellgren-Lawrence grade 2) were randomized to receive either a single 100-unit BoNT-A injection into the target ankle (n = 38) or a single hyaluronate injection plus 12 sessions of rehabilitation exercise (30 minutes/day, 3 times/week for 4 weeks) (n = 37). The primary outcome measure was the Ankle Osteoarthritis Scale (AOS). Secondary outcome measures included American Orthopedic Foot and Ankle Society (AOFAS) Ankle/Hindfoot Score, visual analog scale (VAS) for ankle pain, single leg stance test (SLS), Timed “Up-and-Go” test (TUG), consumption of rescue analgesics and global patient satisfaction. There were no significant between-group differences in total AOS scores, pain subscale and disability subscale scores (adjusted mean difference AMD = -0.2, 95% CI = (-0.5, 0.2), p = 0.39; AMD = -0.1, 95% CI = (-0.5, 0.3), p = 0.57; AMD = -0.2, 95% CI = (-0.6, 0.2), p = 0.36). The 2 groups showed no significant differences in AOFAS, VAS, SLS, TUG scores and consumption of rescue analgesics at each follow-up visit, except that the hyaluronate group improved more in SLS than the BoNT-A group at 1-month follow-up. Patients’ satisfaction rate was high, with no serious adverse events. There was no difference in adverse events between the two groups (p = 1.00). Treatment with intraarticular BoNT-A or hyaluronate injection plus rehabilitation exercise was associated with improvements in pain, physical function and balance in patients with ankle OA. These effects were rapid at 2 weeks and might last for at least 6 months. There was no difference in effectiveness between the two interventions. The trial was registered at clinical trials.gov (Registry number NCT01760577 ).

Foot pain is highly prevalent in the community. Foot pain and ankle pain occurring on most days are reported by 25% and 15% of older adults, respectively. Both foot and ankle pain are more prevalent in women than men but no consistent relationship with age has been identified. Pain within the foot most commonly occurs at the toes or forefoot, followed by the arch or ball, with the heel and hindfoot least frequently affected. Foot pain is commonly associated with locomotor disability. Almost two-thirds of adults aged 50 years and over with foot pain report problems related to physical function. Eight percent of older adults without disabling foot pain experience its onset over a three-year period whereas resolution appears to be uncommon, with 70% of those with disabling symptoms still having them three years later. Onset of physical impairment associated with foot pain most commonly relates to increased reliance on vehicular transport, and difficulty walking and standing. Furthermore, foot pain is also associated with poor balance and risk of falling. Although musculoskeletal foot problems account for a substantial number of consultations in primary care, it appears that only a minority of people with foot problems consult about them. Eight percent of primary care musculoskeletal consultations (290 primary care consultations per 10,000 registered patients per year) involve musculoskeletal foot problems. However, only 20% of people with musculoskeletal foot problems see their family doctor over a three-year period and a similar proportion of those with foot pain see a podiatrist over twelve months. Primary care consultation with a musculoskeletal foot problem is more likely in those with foot pain, those who consult frequently about other problems, and those who believe effective treatments are available. Most primary care consultations for musculoskeletal foot problems are categorized by family doctors using non-specific terms describing pain location, eg foot pain or ankle pain, with specific diagnostic codes, eg plantar fasciitis, used less frequently. In summary, foot pain is a common problem both in the community and in primary care, and frequently associates with locomotor disability. However, only a small proportion of those with musculoskeletal foot problems consult about them. Further studies are needed to explore why people choose to consult a particular health care professional about their foot problem, how the decision to consult can be influenced, and how foot pain and problems are managed in different healthcare settings.

Symptoms associated with pes planovalgus or flatfeet occur frequently, even though some people with a flatfoot deformity remain asymptomatic. Pes planovalgus is proposed to be associated with foot/ankle pain and poor function. Concurrently, the multifactorial weakness of the tibialis posterior muscle and its tendon can lead to a flattening of the longitudinal arch of the foot. Those affected can experience functional impairment and pain. Less severe cases at an early stage are eligible for non-surgical treatment and foot orthoses are considered to be the first line approach. Furthermore, strengthening of arch and ankle stabilising muscles are thought to contribute to active compensation of the deformity leading to stress relief of soft tissue structures. There is only limited evidence concerning the numerous therapy approaches, and so far, no data are available showing functional benefits that accompany these interventions. After clinical diagnosis and clarification of inclusion criteria (e.g., age 40–70, current complaint of foot and ankle pain more than three months, posterior tibial tendon dysfunction stage I & II, longitudinal arch flattening verified by radiography), sixty participants with posterior tibial tendon dysfunction associated complaints will be included in the study and will be randomly assigned to one of three different intervention groups: (i) foot orthoses only (FOO), (ii) foot orthoses and eccentric exercise (FOE), or (iii) sham foot orthoses only (FOS). Participants in the FOO and FOE groups will be allocated individualised foot orthoses, the latter combined with eccentric exercise for ankle stabilisation and strengthening of the tibialis posterior muscle. Participants in the FOS group will be allocated sham foot orthoses only. During the intervention period of 12 weeks, all participants will be encouraged to follow an educational program for dosed foot load management (e.g., to stop activity if they experience increasing pain). Functional impairment will be evaluated pre- and post-intervention by the Foot Function Index. Further outcome measures include the Pain Disability Index, Visual Analogue Scale for pain, SF-12, kinematic data from 3D-movement analysis and neuromuscular activity during level and downstairs walking. Measuring outcomes pre- and post-intervention will allow the calculation of intervention effects by 3×3 Analysis of Variance (ANOVA) with repeated measures. The purpose of this randomised trial is to evaluate the therapeutic benefit of three different non-surgical treatment regimens in participants with posterior tibial tendon dysfunction and accompanying pes planovalgus. Furthermore, the analysis of changes in gait mechanics and neuromuscular control will contribute to an enhanced understanding of functional changes and eventually optimise conservative management strategies for these patients.

Background The analysis of internet search traffic may present the opportunity to gain insights into general trends and patterns in information seeking behaviour related to medical conditions at a population level. For prevalent and widespread problems such as foot and ankle pain, this information has the potential to improve our understanding of seasonality and trends within these conditions and their treatments, and may act as a useful proxy for their true incidence/prevalence characteristics. This study aimed to explore seasonal effects, general trends and relative popularity of internet search terms related to foot and ankle pain over the past decade. Methods We used the Google Trends tool to obtain relative search engine traffic for terms relating to foot and ankle pain and common treatments from Google search and affiliated pages for major northern and southern hemisphere English speaking nations. Analysis of overall trends and seasonality including summer/winter differences was carried out on these terms. Results Searches relating to general foot pain were on average 3.4 times more common than those relating to ankle pain, and twice as common as searches relating to heel pain. Distinct seasonal effects were seen in the northern hemisphere, with large increases in search volumes in the summer months compared to winter for foot (p = 0.004, 95 % CI [22.2–32.1]), ankle (p = 0.0078, 95 % CI [20.9–35.5]), and heel pain (p = 0.004, 95 % CI [29.1–45.6]). These seasonal effects were reflected by data from Australia, with the exception of ankle pain. Annual seasonal effects for treatment options were limited to terms related to foot surgery and ankle orthoses (p = 0.031, 95 % CI [3.5–20.9]; p = 0.004, 95 % CI [7.6–25.2] respectively), again increasing in the summer months. Conclusions A number of general trends and annual seasonal effects were found in time series internet search data for terms relating to foot and ankle pain. This data may provide insights into these conditions at population levels.

Methods We performed prospective analysis and followed up 76 patients enrolled from January 2012 to December. 2013 for at least 6 months excepting the 5 patients who were lost follow-up, 71 patients (bilateral: 9, unilateral: 62, total 80 cases) were analyzed. There were 8 men, 63 women and the average age were 69.6 years old (56-79). All surgery were performed by one operator and posterior cruciate ligament stabilized knee arthroplasty was done in all cases. Subjective ankle pain was evaluated by visual analogue scale (VAS) and clinical results were evaluated by AO-FAS ankle-hindfoot scale and SF-36. We described radiologic parameters around the hindfoot and ankle joint including talar tilt, tibial-ankle surface angle, medial clear space, frontal tibial ground angle, frontal talar gound angle, hindfoot alignment view angle and measured the amount of change of knee alignment by comparing preoperative and postoperative X-rays. We divided cases into 4 groups, two with increased ankle pain postoperatively in previous ankle pain group and newly developed pain postoperatively. Pain was aggrevated compared preoperatively was other subgroup, and the other had no change. We compared 4 groups in each parameter and analyzed statistically (SPSS v13.0).
