Due to current measurement, sizing and fitting approaches, poor bra fit is prevalent amongst larger breasted women. The impact of improving bra fit hasn't yet been explored. This pre-clinical study aimed to explore immediate and short-term biomechanical responses to changing breast support garment. Asymptomatic participants (n=24) performed a static standing task, drop jumps and seated typing whilst kinematic data from the breasts and spine were recorded. Three breast support conditions were assessed: Usual, professionally fitted bra in the immediate term (PFB), and the same professionally fitted bra after four weeks wear (PFB). Bra fit assessments were included for both bras. All participants failed the bra fit assessment when wearing the Usual bra and 67% (n=16) failed when wearing the PFB. Less bra fit issues were present in the PFB, resulting in immediate biomechanical changes relating to breast support and spinal posture, yet nothing in the short term (PFB). This research sets the foundations for future work to investigate whether the implementation of better fitting breast support garments can influence musculoskeletal pain amongst larger breasted women, whilst attributing potential improvement of symptoms, objective measures of breast support and spinal posture.
由于目前的测量、尺寸和适配方法,大乳房女性的胸罩适配不良较为普遍。改善胸罩适配的影响尚未得到探索。这项临床前研究旨在探索改变乳房支撑服装后即刻和短期的生物力学反应。无症状参与者(n=24)在静态站立任务、跳落和坐姿打字时进行了测试,同时记录了乳房和脊柱的运动学数据。评估了三种乳房支撑条件:通常情况下的胸罩、短期内专业适配的胸罩(PFB),以及佩戴四周后的相同专业适配的胸罩(PFB)。对这两款胸罩都进行了胸罩适配评估。所有参与者在佩戴通常的胸罩时都未能通过胸罩适配评估,而在佩戴 PFB 时,有 67%(n=16)未能通过。PFB 中的胸罩适配问题较少,导致与乳房支撑和脊柱姿势相关的即刻生物力学变化,但在短期内没有变化(PFB)。这项研究为未来的工作奠定了基础,以调查更好的胸罩支撑服装的实施是否可以影响大乳房女性的肌肉骨骼疼痛,同时归因于症状、乳房支撑和脊柱姿势的客观改善。
