Risk Factors for Plantar Fasciitis Among Assembly Plant Workers.

OBJECTIVE: The objective of this study was to determine the relative contributions of work activity (time spent standing, walking, or sitting), floor surface characteristics, weight, body mass index, age, foot biomechanics, and other demographic and medical history factors to the prevalence of plantar fasciitis.

DESIGN: A cross-sectional observational study design was used. SETTING: The study site was an automobile engine assembly plant. PARTICIPANTS: Full-time employees of the assembly plant who had been working at least 6 months. ASSESSMENT OF RISK FACTORS: The independent variables included baseline demographics, medical history, ergonomic exposures, psychosocial factors, discomfort ratings, shoe characteristics, and foot biomechanics. MAIN OUTCOME MEASUREMENTS: The dependent variable was the finding of plantar fasciitis on physical examination.

RESULTS: The study demonstrated that forefoot pronation on physical examination, high metatarsal pressure on the gait assessment, increasing time spent standing on hard surfaces, increased time spent walking, medium tenure at the plant, and an increased number of times getting in and out of the vehicle (for the truck/forklift drivers) increased the risk of presenting with plantar fasciitis. Rotation of shoes during the work week was found to reduce the risk of presenting with plantar fasciitis. Increased supervisor support showed a trend toward reducing the prevalence of plantar fasciitis.

CONCLUSIONS: Plantar fasciitis is relatively common in the manufacturing setting. These findings suggest several options for primary and secondary prevention strategies. Shoe rotation may be an effective strategy that may be used as either a primary or secondary strategy. The use of shoe orthoses with a medial longitudinal arch and metatarsal pad may be used as a preventive or treatment strategy. Work stations that decrease the percentage of time walking or standing on hard surfaces (eg, allowing workers to alternate between sitting and standing postures or providing cushioning mats for concrete surfaces) may lower the risk for plantar fasciitis

Anyone have the full article they could share? Wouldn't mind a closer peek at the methodology etc. Always interested in a cross-sectional design which suggests causality...

Risk factors for foot and ankle disorders among assembly plant workers.
Werner RA, Gell N, Hartigan A, Wiggermann N, Keyserling WM.
Am J Ind Med. 2010 Sep 22. [Epub ahead of print]

BACKGROUND: Jobs that necessitate prolonged standing and walking activities are commonly associated with worker's complaints of foot and ankle pain. The objective of this study was to determine the relative contributions of work activity (time spent standing, walking, or sitting), floor surface characteristics, weight, BMI, age, foot biomechanics, and other demographic and medical history factors to the prevalence of foot and ankle disorders.

METHODS: A cross-sectional observational study design was used to evaluate employees of an engine manufacturing plant. The main outcome variable was foot or ankle disorders defined by pain and a positive physical examination. The independent variables included baseline demographics, medical history, ergonomic exposures, psychosocial factors, shoe characteristics and foot biomechanics.

RESULTS: Twenty-four percent of the cohort met the case definition of foot/ankle disorder with 10% defined as new cases. Fifty-two percent had symptoms of foot/ankle. An increased risk of presenting with foot/ankle disorders was associated with high metatarsal pressure on gait assessment, increased time spent walking, female gender, reported high job dissatisfaction, a history of rheumatoid arthritis, osteoporosis or vascular disorder. For the truck/forklift drivers, an increased number of times getting in and out of the vehicle was associated with a higher prevalence of ankle/foot problems.

CONCLUSIONS: An increased risk is associated with higher metatarsal pressure and increased time spent walking. These findings suggest several options for primary and secondary prevention strategies. The use of shoe orthoses with a medial longitudinal arch and metatarsal pad as well as including optional sit/stand workstations may be helpful

Assessment of musculoskeltal system pain complaints reported by forestry workers.
Choina P et al
Ann Agric Environ Med. 2018 Jun 20;25(2):338-344.

INTRODUCTION:
According to the European Occupational Diseases Statistics (EODS-2005) diseases related with musculoskeletal disorders occupy the first position on the obligatory list of occupational diseases. These disorders most frequently occur in the agriculture-hunting-forestry sector in such countries as: Finland, Holland, Germany, France and Spain (data: EU-OSHA).

MATERIAL AND METHODS:
The study included a selected group of males - 414 forestry workers, employees of the State Forests, aged 25-65, mean age 48. The control group were 119 office workers aged 23-64, mean age 45.8. The basic research instrument was a questionnaire designed by specialists concerning pain complaints occurring in 7 areas of the motor system: neck, arms, upper and lower back, hips, knees and feet.

RESULTS:
The results of the survey showed that in the selected group of forestry workers, among 7 investigated areas of the motor system, the most frequently reported pain complaints involved the lower part of the spine (272 persons, 65.7% of the total number of respondents). In the control group such pain complaints occurred in 55.5% (66) of office workers (p = 0.04). Forestry workers most often described this pain as permanent, radiating to the leg, or as an acute pain. According to the frequency of reporting pain, the area of the knees was placed on the second position (214 foresters; 51.7%).

CONCLUSIONS:
The work of a forester which consist, among other things, in relocation on foot or by vehicle over long distances along an uneven terrain and in various weather conditions, is a risk factor of the occurrence of musculosceletal disorders concerning the low back and knees.
