The effect of insoles on the incidence and severity of low back pain among workers whose job involves long-distance walking

“…It was understood that the prolonged standing position led to an increased sensitivity in the plantar region 23,31 . According to Shabat et al 12 and King 9 , the use of insoles provided a greater sense of comfort to the feet, which, in turn, led to a subjective feeling of improvement in complaints triggered by standing postures. This is an obvious but relevant conclusion in this discussion, and the literature suggests that standing on a soft surface is less fatiguing and more comfortable than on a hard surface 8,9 .…”

“…However, only Basford and Smith 11 studied the use of insoles to verify the reduction in complaints, but without associating them with changes in weight load or other mechanical explanations. Sobel et al 6 and Shabat et al 12 examined the use of insoles in the workplace, but in populations who walked during work. In this sense, there are gaps for interventions aimed at standing and static positions in symptomatic workers, especially those related to plantar performance and comparisons of insoles found in the national market.…”

“…The use of plantar orthoses has been recommended to reduce painful conditions related to the feet [13][14][15] and spine 12,16 . It is suggested that these devices may affect the distribution of plantar loads in contact with rigid surfaces, thus reducing the absorption of shocks and minimizing pain in the lower limbs and lumbar spine 6 because a better distribution of body weight on the plantar area provides proper alignment to the pelvis and, therefore, to the spine 17 .…”

“…Jannink et al 14 evaluated the effectiveness of customized insoles in patients with degenerative foot problems and concluded that they were effective in reducing symptoms and plantar pressure. Shabat et al 12 found positive effects of the use of insoles on the painful conditions of the lumbar spine in people whose work involved long-distance walking. In contrast, Sahar et al 16 concluded that there was a need for better tests to confirm the associations between insoles and back pain prevention.…”

“…Few studies have evaluated the effectiveness of insole use 6,11,12 within the work environment, an appropriate setting for the manifestation of ergonomic symptoms. Furthermore, no studies have compared different types of insole materials in the work environment.…”
