Background and purposeChemotherapy-induced peripheral neuropathy (CIPN) occurs in 19%–85% of patients undergoing cancer treatment. Due to the high symptom burden, specifically pain in the soles of feet, we explore the role of elastic therapeutic (ET) taping for treatment of CIPN.Case descriptionWe report two cases of patients with CIPN-induced foot pain while admitted to the hospital. Their background information, including chemotherapy history, treatments trialed and effects of ET on their pain, is discussed. Each patient underwent ET using the epidermis, dermis, fascia technique for CIPN. An occupational therapist applied ET to the plantar surface of both feet to the ankle with 0% stretch on the tape for 24–96 hours. We also showed the effect of symptom improvement in their individualized rehabilitation session following application of ET.OutcomesPain score, verbally documented by 10 point numerical pain rating scale, decreased by >50% in both patients within 24 hours of application. This reflects a substantial improvement in pain with the intervention of ET. This allowed for improved tolerance in engaging in functional mobility, with improvement in distances ambulated.DiscussionET taping of the distal leg and foot showed pain improvement for these two patients. Our findings suggest that a clinical trial aimed at better characterising the role of ET in these patients is justified.

Prior studies have shown that self- and manual massage (SMM) increases flexibility in non-adjacent body areas. It is unclear whether this also influences performance in terms of force generation. Therefore, this study investigated the effect of SMM on the plantar surface on performance in the dorsal kinetic chain. Seventeen young participants took part in this within-subject non-randomized controlled study. SMM was applied on the plantar surface of the dominant leg, but not on the non-dominant leg. A functional performance test of the dorsal kinetic chain, the Bunkie Test, was conducted before and after the intervention. We measured the performance in seconds for the so-called posterior power line (PPL) and the posterior stabilizing line (PSL). The performance of the dominant leg in the Bunkie Test decreased significantly by 17.2% from (mean ± SD) 33.1 ± 9.9 s to 27.4 ± 11.1 s for the PPL and by 16.3% from 27.6 ± 9.8 s to 23.1 ± 11.7 s for the PSL. This is in contrast to the non-dominant leg where performance increased significantly by 5.1% from 29.7 ± 9.6 s to 31.1 ± 8.9 s for the PPL and by 3.1% from 25.7 ± 1.5 s to 26.5 ± 1.7 s for the PSL. SMM interventions on the plantar surface might influence the performance in the dorsal kinetic chain.

Reconstruction of posterior heel defects is important because it requires thick and durable skin that can withstand pressure and shear from shoe and bed contact. Therefore, the sensate flap could be a better option for the defect. This paper reports on the safety of a medial plantar sensory flap for these defects as well as an objective measurement of the sensation of the medial plantar flap and the plantar surface distal to the donor site. Twelve patients had soft-tissue defects in the posterior heel and underwent reconstructive surgery using a proximally based sensate medial plantar sensory flap. Cases of plantar defects involving not posterior heel were excluded. For wider flap coverage, special neurovascular dissection was required. We evaluated levels of sensation quantitatively using Semmes–Weinstein (SW) monofilaments and a two-point discriminator at the final follow-up. All flaps survived without major complications. Postoperative follow-up was 12 to 64 months (mean 26 months). All 12 flaps healed without postoperative complications. There was no significant difference in minimal two-point discrimination and SW evaluator size between the transferred medial plantar flap area and the contralateral heel area or between the plantar area distal to the donor site and the contralateral side. Patients could walk normally and sleep without protective shoes or brace. A proximally based sensate medial plantar flap is a good option for the reconstruction of posterior heel defects. It can restore the characteristics of the posterior heel for shoe wearing and sleeping.

Background: Diabetic foot ulcers (DFUs) are a leading cause of disability and morbidity. There is an unmet need for a simple, practical, home method to detect DFUs early and remotely monitor their healing. Method: We developed a simple, inexpensive, smartphone-based, “ Foot Selfie” system that enables patients to photograph the plantar surface of their feet without assistance and transmit images to a remote server. In a pilot study, patients from a limb-salvage clinic were asked to image their feet daily for six months and to evaluate the system by questionnaire at five time points. Transmitted results were reviewed weekly. Results: Fifteen patients (10 male) used the system after approximately 5 minutes of instruction. Participants uploaded images on a median of 76% of eligible study days. The system captured and transmitted diagnostic quality images of the entire plantar surface of both feet, permitting clinical-management decisions on a remote basis. We monitored 12 active wounds and 39 pre-ulcerative lesions (five wounds and 13 pre-ulcerative lesions at study outset); we observed healing of seven wounds and reversal of 20 pre-ulcerative lesions. Participants rated the system as useful, empowering, and preferable to their previous methods of foot screening. Conclusions: With minimal training, patients transmitted diagnostic-quality images from home on most days, allowing clinicians to review serial images. This system permits inexpensive home foot screening and monitoring of DFUs. Further studies are needed to determine whether it can reduce morbidity of DFUs and/or the associated cost of care. Artificial intelligence integration could improve scalability.

AbstractInvestigating the morphological differences of the calcaneus in humans and great apes is crucial for reconstructing locomotor repertories of fossil hominins. However, morphological variations in the calcaneus of the great apes (chimpanzees, gorillas, and orangutans) have not been sufficiently studied. This study aims to clarify variations in calcaneal morphology among great apes based on three-dimensional geometric morphometrics. A total of 556 landmarks and semilandmarks were placed on the calcaneal surface to calculate the principal components of shape variations among specimens. Clear interspecific differences in calcaneal morphology were extracted, corresponding to the degree of arboreality of the three species. The most arboreal orangutans possessed comparatively more slender calcaneal tuberosity and deeper pivot region of the cuboid articular surface than chimpanzees and gorillas. However, the most terrestrial gorillas exhibited longer lever arm of the triceps surae muscle, larger peroneal trochlea, more concave plantar surface, more inverted calcaneal tuberosity, more everted cuboid articular surface, and more prominent plantar process than the orangutans and chimpanzees. These interspecific differences possibly reflect the functional adaptation of the calcaneus to locomotor behavior in great apes. Such information might be useful for inferring foot functions and reconstructing the locomotion of fossil hominoids and hominids.

Mechanical and thermal stimuli were used to evaluate neuropathic pain-like behavior in animal models usually. Mechanical stimulation of paw plantar surface is commonly used to determine mechanical allodynia. In the present study, paw withdrawal response to plantar surface stimulation was compared with paw withdrawal response to dorsal surface stimulation. To this end, a total of 30 female Wistar rats (180-220 g), were assigned randomly to three groups as intact (without any manipulation), sham (incision of skin and muscles without nerve injury), and neuropathy (sciatic nerve lesion) with 10 in each group. To induction of neuropathy (chronic constriction injury), four movable ligations were established around the sciatic nerve using catgut chromic suture with a distance of one millimeter apart and then wound incision was closed. In the sham group, the incision site was closed without nerve ligation. Mechanical allodynia was examined by Von Frey filaments for four weeks. The findings indicated that the paw withdrawal threshold following dorsal surface stimulation was significantly reduced compared to the sham group at day 21 post-surgery. Moreover, paw withdrawal threshold following plantar surface stimulation significantly decreased compared to the sham group at day 21 post-surgery. The present results regarding the sham group showed that the paw withdrawal threshold after mechanical stimulation of the plantar surface was not significantly different from that of the dorsal surface paw. In addition, and there was no significant difference between the paw withdrawal response to plantar surface and dorsal one. In conclusion, paw withdrawal threshold to plantar surface mechanical stimulation was not significantly different from one in dorsal surface following neuropathic pain induced by chronic constriction injury.

The effectiveness of adding plantar-surface texture to improve balance has been demonstrated in a variety of demographics. It is critical to investigate whether textured insoles can improve balance in people with knee osteoarthritis (OA), who have compromised the somatosensory function of the affected joint and, as a result, are at a higher risk of falling. Thus, this study investigated the degree of benefit from the use of textured insoles for improving balance and compared the balance of people with knee OA to healthy matched peers. This study included eighteen people with knee OA and eighteen healthy, aged, gender, height, weight, and BMI matched controls who were assessed on balance using the sensory organization test and the motor control test. Balance was improved in both groups when the textured insoles were worn, and the healthy knee group demonstrated significantly better balance performance than the knee OA group. The benefits of this study for individuals with knee OA are that it may lead to the development of an evidence-based footwear intervention that is noninvasive, simple to use, and inexpensive, in addition to allowing the user to self-manage and the ability to reduce the risk of falls, thereby improving their quality of life.

We report the case of a 60-year-old woman with a schwannoma of the medial plantar nerve. She presented with the complaint of pain for about 2 years and a painful lesion in the medial plantar region of the left forefoot and on the second toe. Physical examination showed well-defined, firm tumor masses painful to palpation on the medial and plantar surface of the left forefoot and second toe. We surgically explored the area and excised 3 lesions, resulting in complete pain relief and no aesthetic complaints. Schwannomas of the medial plantar nerve are rare tumors, with only a few reports of cases extending to the forefoot. The finding of multiple schwannomas may be a red flag for the possible existence of local, painful, nerve lesions despite a negative Tinel sign. Appropriate surgical planning contributed to our successful intervention, without aesthetic, painful, or functional sequelae for the patient.

Background: Painful lesions affecting the plantar aspect of the foot are routinely encountered in daily practice, and plantar wart, corn, and callus are the most common conditions. Although the clinical examination is sufficient to clinch an accurate diagnosis, atypical presentations indicate the need for invasive investigations like skin biopsy. Here we evaluated dermoscopic patterns of painful lesions affecting the plantar surface. Objectives: The current study aimed to, firstly, investigate the dermoscopic patterns and differentiate between painful papules and plaques on the foot, and, secondly, to analyze the histopathological correlation of these dermoscopic patterns. Methods: Following a cross-sectional design, the current study was carried out on patients with the clinical diagnosis of painful lesions of foot suggestive of plantar wart, corn, and callus referring to a tertiary care center from June 2019 to Jan 2020. Dermoscopy analysis and biopsy were performed for all participants. Results: Among 92 patients with painful plantar lesions, 56, 22, and 15 had a plantar wart, corn, and callus, respectively. Dermoscopy of warts revealed red dots (89.28%) and yellow halo (82.14%). A translucent central core (100%) and whitish ring (81.81%) on dermoscopy of patients with corn. Dermoscopy of callus demonstrated opaque yellow area in all (100%) the patients. Dermatoglyphics were absent in plantar wart in contrast to corn and callus, wherein they were preserved. Conclusions: Dermoscopy can be considered as a rapid, non-invasive, diagnostic tool in the daily practice of a dermatologist. Here, it assisted in distinguishing clinically akin painful plantar papules and plaques. These dermoscopic patterns also were well correlated histopathologically.
