“…During walking skin movement and furthermore detachment of the CEPG were recognized. These problems might be related to the high inter-subject variance for the hindfoot-tibia motion mainly in the frontal plane, which was found in this study, and which has also been reported by previous studies [28,29].…”

“…The investigator attached 2 rigid plastic plates of markers to the participant's shank using tape prewrap and attached 28 individual 9.5-mm reflective markers (MoCap Solutions, Huntington Beach, CA) using double-sided adhesive tape at specific anatomical landmarks. Marker placement was according to the Oxford foot model 22,23 : The examiner attached anatomical markers bilaterally on the lateral and medial femoral epicondyles, lateral and medial malleoli, proximal and distal fifth metatarsals, distal second metatarsals, proximal and distal first metatarsals, and lateral, medial and posterior calcanei. The Oxford foot model method is reliable for calculating adult hindfoot motion (ICC ¼ 0.90-0.97, SEM 90 ¼ 0.898-2.218).…”

Context: Why some individuals with ankle sprains develop functional ankle instability and others do not (ie, copers) is unknown. Current understanding of the clinical profile of copers is limited. Objective: To contrast individuals with functional ankle instability (FAI), copers, and uninjured individuals on both self-reported variables and clinical examination findings. Design: Cross-sectional study. Setting: Sports medicine research laboratory. Patients or Other Participants: Participants consisted of 23 individuals with a history of 1 or more ankle sprains and at least 2 episodes of giving way in the past year (FAI: Cumberland Ankle Instability Tool [CAIT] score = 20.52 ± 2.94, episodes of giving way = 5.8 ± 8.4 per month), 23 individuals with a history of a single ankle sprain and no subsequent episodes of instability (copers: CAIT score = 27.74 ± 1.69), and 23 individuals with no history of ankle sprain and no instability (uninjured: CAIT score = 28.78 ± 1.78). Intervention(s): Self-reported disability was recorded using the CAIT and Foot and Ankle Ability Measure for Activities of Daily Living and for Sports. On clinical examination, ligamentous laxity and tenderness, range of motion (ROM), and pain at end ROM were recorded. Main Outcome Measure(s): Questionnaire scores for the CAIT, Foot and Ankle Ability Measure for Activities of Daily Living and for Sports, ankle inversion and anterior drawer laxity scores, pain with palpation of the lateral ligaments, ankle ROM, and pain at end ROM. Results: Individuals with FAI had greater self-reported disability for all measures (P < .05). On clinical examination, individuals with FAI were more likely to have greater talar tilt laxity, pain with inversion, and limited sagittal-plane ROM than copers (P < .05). Conclusions: Differences in both self-reported disability and clinical examination variables distinguished individuals with FAI from copers at least 1 year after injury. Whether the deficits could be detected immediately postinjury to prospectively identify potential copers is unknown.

“…Bone models were obtained from previous researches of our research group [17]. In recent researches, foot has been widely modelled as multiple segments while the number of the segments range from 2 to 4 [18][19][20][21][22]. This paper has divided the foot into 4 parts: rear-foot composed of calcaneus and talus, mid-foot composed of navicular, cuneiforms, cuboid, fore-mid foot consisted of first to fifth metatarsal, fore-foot composed of phalanges.…”

Abstract. This paper aims to simulate two stretching methods adopted in plantar fasciitis treatment in MSC.ADAMS, Achilles tendon stretch and plantar fascia stretch. Clinical evidence has been accumulated that stretching is effective in relieving heel pain caused by plantar fasciitis. While plantar fascia stretching is conceived to be more effective than the traditional Achilles tendon stretch, the reason leading to this difference has not been identified yet. A multi-segment foot model consisted of ligaments, plantar fascia, plantar soft tissue was constructed and then validated by comparing the ground reaction forces and joint rotation angles obtained in a gait simulation with previous research results. The model was then applied in finding out the root cause in these two stretching methods by analysing the deformation of plantar fascia. Achilles tendon stretch was performed to collect kinematic data of tibia using NDI, which was used to drive the simulation. In the plantar fascia stretch, a rotational plate was placed beneath the fore-foot and had a range of motion from 0° to 20°. The forefoot was supported and lifted to simulate the stretching process. Deformation of the plantar fascia under two stretching methods were compared. The result shows that average deformation in Achilles tendon is smaller than that of plantar fascia stretch which may cause the therapeutic difference between these two stretch methods. This analysis method could also be applied in refining physical therapy treatment.
