Comparing the Efficacy of Acupressure and Foot Reflexology on Sleep Quality in Patients With Leukemia: A Comparative Clinical Trial.

BACKGROUND: Among leukemia patients, sleep disruptions are prevalent and can profoundly affect their overall quality of life. Acupressure and foot reflexology, modalities rooted in traditional Chinese medicine, have garnered attention for their potential to address sleep disturbances and mitigate associated symptoms. METHODS: This research utilized a randomized controlled trial with a pretest-posttest design involving 102 leukemia patients admitted to Imam Khomeini Hospital in Urmia. Participants were randomly allocated to 3 groups: acupressure (n = 34), reflexology (n = 34), or control (n = 34). Prior to the intervention, patients completed a demographic survey and the Pittsburgh Sleep Quality Index (PSQI) for baseline assessments. Acupressure involved stimulation of the SP6 point twice daily for 10 minutes over 4 weeks, while reflexology entailed daily 10-minute sessions with sweet almond oil on the soles for the same duration. The control group received standard care without additional interventions. Following the 4-week intervention period, post-intervention evaluations were conducted using identical measurement tools. RESULTS: The findings underscored the efficacy of both acupressure and foot reflexology in significantly improving sleep quality within the intervention groups (P < .001). Initially, there were no notable differences in sleep quality among the 3 groups (P > .05). Subsequently, pairwise comparisons adjusted with Bonferroni corrections revealed significant disparities in sleep quality between the acupressure and reflexology groups compared to the control group (P < .001). However, post-intervention analysis indicated no statistically significant variance in enhancing sleep quality between the acupressure and foot reflexology groups (P < .05). CONCLUSION: This study demonstrates that acupressure and foot reflexology interventions can enhance sleep quality in individuals with leukemia. These findings support the effectiveness of these complementary modalities, offering targeted relief and relaxation. While these non-invasive therapies show promise in improving well-being, further research is needed to confirm and expand upon these results due to study limitations.

A finite element model of human hindfoot and its application in supramalleolar osteotomy.

BACKGROUND: The majority of the ankle osteoarthritis cases are posttraumatic and affect younger patients with a longer projected life span. Hence, joint-preserving surgery, such as supramalleolar osteotomy becomes popular among young patients, especially those with asymmetric arthritis due to alignment deformities. However, there is a lack of biomechanical studies on postoperative evaluation of stress at ankle joints. We aimed to construct a verifiable finite element model of the human hindfoot, and to explore the effect of different osteotomy parameters on the treatment of varus ankle arthritis. METHODS: The bones of the hindfoot are reconstructed using normal CT tomography data from healthy volunteers, while the cartilages and ligaments are determined from the literature. The finite element calculation results are compared with the weight-bearing CT (WBCT) data to validate the model. By setting different model parameters, such as the osteotomy height (L) and the osteotomy distraction distance (h), the effects of different surgical parameters on the contact stress of the ankle joint surface are compared. FINDINGS: The alignment and the deformation of hindfoot bones as determined by the finite element analysis aligns closely with the data obtained from WBCT. The maximum contact stress of the ankle joint surface calculated by this model increases with the increase of the varus angle. The maximum contact stresses as a function of the L and h of the ankle joint surface are determined. INTERPRETATION: The relationship between surgical parameters and stress at the ankle joint in our study could further help guiding the planning of the supramalleolar osteotomy according to the varus/valgus alignment of the patients.

Discrepancies in plantar pressure distribution between affected and unaffected sides in patients with plantar fasciitis.

PURPOSE: A fundamental understanding of plantar pressure distribution is important for prescribing an appropriate orthosis and applying nonoperative methods, such as stretching exercises, for the treatment of plantar fasciitis. Despite existing research on plantar pressure distribution, discrepancies between affected and unaffected sides in unilateral plantar fasciitis patients warrant further investigation. This study aimed to evaluate the plantar pressure distribution in patients with unilateral plantar fasciitis by comparing it with that on the contralateral unaffected side. METHODS: We retrospectively reviewed records from 20 consecutive patients diagnosed with unilateral plantar fasciitis, using the unaffected side as the control. The emed® pedobarographic system was used to measure the plantar pressure distribution during gait. The analysis was performed using a 4-mask configuration (toes, forefoot, midfoot, and hindfoot). RESULTS: Both sides showed no significant differences in radiographic parameters. The affected side showed a significantly higher contact area, maximum force, and force-time integrals in the midfoot. However, the unaffected side demonstrated significantly higher maximum force and force-time integrals in the hindfoot. There was no difference in the distribution of the peak pressure and pressure-time integrals between the two sides in all mask regions. The increased contact area and maximum force in the midfoot on the side with plantar fasciitis may result from heel pain-induced weight transfer from the hindfoot. CONCLUSION: The findings of this study provide a basic understanding of plantar pressure distribution in the treatment of plantar fasciitis and highlight the importance of considering inter-side differences when designing treatment interventions or orthotic devices.

Cold hypersensitivity in the hands and feet is associated with erectile dysfunction in young Taiwanese men.

Cold hypersensitivity in the hands and feet (CHHF) is a protective or predisposing factor for many diseases; however, the relationship between CHHF and erectile dysfunction (ED) remains unclear. We aimed to investigate associations between CHHF and ED among young men of Southeast Asian origin. In this cross-sectional study, sexually active Taiwanese men aged 20-40 years were enrolled via an online questionnaire comprising general demographic information, comorbidities, subjective thermal sensations of their hands and feet in the past 6 months, and their erectile function using the International Index of Erectile Function-5 (IIEF-5). Participants who reported cold sensation of hands and feet were classified to have CHHF; those with IIEF-5 score ≤ 21 were considered to have ED. Total 54.2% and 27.9% of participants had ED and CHHF, respectively. Men with CHHF were significantly younger, had lower body mass index and IIEF-5 scores (p < 0.001), and a lower prevalence of diabetes mellitus (p = 0.033) along with higher prevalence of ED, psychiatric disorders, and insomnia (p < 0.001). After adjusting for predisposing factors of ED, CHHF (odds ratio 1.410, 95% confidence interval 1.159-1.714; p = 0.001) remained an independent predictor of ED. Thus, CHHF is independently associated with ED, affecting more than a quarter of young Taiwanese men. Autonomic dysregulation and subclinical endothelial dysfunction may be common pathophysiologies of CHHF and ED.

Impact of the medial displacement calcaneal osteotomy on foot biomechanics: a systematic literature review.

INTRODUCTION: Progressive collapsing foot deformity (PCFD), formally known as "adult-acquired flatfoot deformity" (AAFFD), is a complex foot deformity consisting of multiple components. If surgery is required, joint-preserving procedures, such as a medial displacement calcaneal osteotomy (MDCO), are frequently performed. The aim of this systematic review is to provide a summary of the evidence on the impact of MDCO on foot biomechanics. MATERIALS AND METHODS: A systematic literature search across two major sources (PubMed and Scopus) without time limitation was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) criteria. Only original research studies reporting on biomechanical changes following a MDCO were included. Exclusion criteria consisted of review articles, case studies, and studies not written in English. 27 studies were included and the methodologic quality graded according to the QUACS scale and the modified Coleman score. RESULTS: The 27 included studies consisted of 18 cadaveric, 7 studies based on biomechanical models, and 2 clinical studies. The impact of MDCO on the following five major parameters were assessed: plantar fascia (n = 6), medial longitudinal arch (n = 9), hind- and midfoot joint pressures (n = 10), Achilles tendon (n = 5), and gait pattern parameters (n = 3). The quality of the studies was moderate to good with a pooled mean QUACS score of 65% (range 46-92%) for in-vitro and a pooled mean Coleman score of 58 (range 56-65) points for clinical studies. CONCLUSION: A thorough knowledge of how MDCO impacts foot function is key in properly understanding the postoperative effects of this commonly performed procedure. According to the evidence, MDCO impacts the function of the plantar fascia and Achilles tendon, the integrity of the medial longitudinal arch, hind- and midfoot joint pressures, and consequently specific gait pattern parameters.

Validating the usefulness of Sudoscan in ATTRv: a single centre experience.

BACKGROUND: Variant transthyretin amyloidosis (ATTRv) can cause sensorimotor and autonomic neuropathy. Objective quantification of sudomotor function may be essential for early diagnosis and early initiation of treatment. The aim of this study is to evaluate the diagnostic value of the Sudoscan® in ATTRv. METHODS: Electrochemical skin conductance (ESC) was measured in V30M ATTRv patients, asymtomatic V30M carriers and healthy controls. Comparisons between the three groups were made using the Kruskal-Wallis test, and ROC curves were used to estimate the discriminatory power of ESC values between groups. RESULTS: ESC was measured in 52 ATTRv patients, 107 asymptomatic carriers and 40 healthy controls. ESC was significantly lower in ATTRv patients compared to asymptomatic carriers and healthy controls in both feet and hands; median values are as follows: 40 µS, 78 µS and 81 µS, respectively (p < 0.001), and 53 µS, 69 µS and 74 µS, respectively (p < 0.001). ESC in feet < 70.5 µS had a sensitivity of 89.7% and specificity of 84.6% to discriminate asymptomatic carriers from patients with ATTRv. CONCLUSION: The determination of ESC by Sudoscan® is a rapid, noninvasive and easily reproducible technique capable of discriminating patients with ATTRv from asymptomatic carriers and healthy controls with adequate sensitivity and specificity.

A Retrospective Study of the Risk Factors for Postoperative Foot or Ankle Pain in 90 Patients with Varus Osteoarthritis of the Knee who Underwent Total Knee Arthroplasty.

BACKGROUND The reasons for foot and ankle pain following total knee arthroplasty (TKA) for knee varus osteoarthritis are unknown. This retrospective study aimed to investigate the risk factors for postoperative foot and ankle pain in patients with varus osteoarthritis of the knee who underwent TKA. MATERIAL AND METHODS We enrolled 90 patients who underwent TKA for varus knee osteoarthritis. The visual analog scale (VAS) was used to evaluate patients' foot or ankle pain before and after surgery. The correlation between independent variables (eg, age, sex, body mass index [BMI], ankle osteoarthritis, and varus angle) and foot and ankle pain in patients with osteoarthritis of the knee was measured. Moreover, radiological changes were compared between the groups with and without worsened pain. RESULTS No significant difference in VAS was found between patients <60 and ≥60 years of age (P>0.05). Male sex and BMI <30 kg/m² were weakly correlated with preoperative foot or ankle pain. However, patients with varus of ≥6° and preexisting ankle osteoarthritis had a higher incidence of foot or ankle pain before surgery. Moreover, no significant differences in radiological changes were found between the groups with and without worsened foot or ankle pain after surgery (P>0.05). CONCLUSIONS In male patients with osteoarthritis of the knee, a BMI <30 kg/m², varus of <6°, and no preexisting ankle osteoarthritis were protective factors for foot and ankle pain. TKA corrected knee and ankle malalignment. Therefore, postoperative foot and ankle pain was not associated only with TKA surgery.

An untreated infection led to a series of unusual signs and symptoms that included difficulty walking.

Functional dystonia in the foot and ankle.

AIMS: To assess the characteristic clinical features, management, and outcome of patients who present to orthopaedic surgeons with functional dystonia affecting the foot and ankle. METHODS: We carried out a retrospective search of our records from 2000 to 2019 of patients seen in our adult tertiary referral foot and ankle unit with a diagnosis of functional dystonia. RESULTS: A total of 29 patients were seen. A majority were female (n = 25) and the mean age of onset of symptoms was 35.3 years (13 to 71). The mean delay between onset and diagnosis was 7.1 years (0.5 to 25.0). Onset was acute in 25 patients and insidious in four. Of the 29 patients, 26 had a fixed dystonia and three had a spasmodic dystonia. Pain was a major symptom in all patients, with a coexisting diagnosis of chronic regional pain syndrome (CRPS) made in nine patients. Of 20 patients treated with Botox, only one had a good response. None of the 12 patients who underwent a surgical intervention at our unit or elsewhere reported a subjective overall improvement. After a mean follow-up of 3.2 years (1 to 12), four patients had improved, 17 had remained the same, and eight reported a deterioration in their condition. CONCLUSION: Patients with functional dystonia typically presented with a rapid onset of fixed deformity after a minor injury/event and pain out of proportion to the deformity. Referral to a neurologist to rule out neurological pathology is advocated, and further management should be carried out in a movement disorder clinic. Response to treatment (including Botulinum toxin (Botox) injections) is generally poor. Surgery in this group of patients is not recommended and may worsen the condition. The overall prognosis remains poor. Cite this article: Bone Joint J 2021;103-B(6):1127-1132.

Differences in lower-extremity kinematics between the male military personnel with and without plantar fasciitis.

OBJECTIVE: To evaluate the factors that influence gait by comparing lower extremity kinematics during the stance phase of the gait cycle between individuals with and without plantar fasciitis. DESIGN: A cross-sectional study. SETTING: Motion analysis research laboratory. PARTICIPANTS: Thirty subjects with plantar fasciitis and 30 aged-matched controls. MAIN OUTCOME MEASURE(S): Range of motion of the lower extremity and multi-segment foot during gait using a three-dimensional motion analysis system. RESULTS: The plantar fasciitis group showed significant differences in motion in the multi-segment foot, ankle, knee, and hip from the control group during various subphases of the stance phase. Specifically, relative to the control group, the plantar fasciitis group had more rearfoot adduction, forefoot eversion, ankle abduction, and hip abduction. They also had less midfoot dorsiflexion, forefoot dorsiflexion, knee extension, knee external rotation, and hip extension (all Ps < 0.05). CONCLUSIONS: Individuals with plantar fasciitis exhibited more flexibility in the ankle-foot complex and poorer quality of lower-extremity movement than the group that did not have plantar fasciitis. Thus, differences in structures in both the ankle-foot complex as well as those in the hip and knee joints appear to be associated with the presence of plantar fasciitis.

The short-term effectiveness of Kinesiology Taping on foot biomechanics in patients with hallux valgus.

BACKGROUND: Hallux valgus, one of the most common foot disorders, contributes to the formation of pain and changes foot biomechanics. OBJECTIVE: To assess the impact of Kinesiology Taping (KT) on foot loading during gait in patients with hallux valgus. METHODS: Forty feet with hallux valgus were examined. Patients wore the KT for a month and the parameters of the foot during gait on a baropodometric platform were measured three times: before taping, immediately after application of taping and after one month's use. RESULTS: The taping had a statistically significant effect on dynamic foot measurements. The maximum and mean foot load (p< 0.001), foot surface (p< 0.001), ratio of forefoot to hindfoot load (p< 0.01) and the proportions of the lateral and medial foot loading (p< 0.05) all changed. During gait cycle, taping significantly increased the load and surface at the first metatarsal head (p< 0.001) while there was a decrease around the second to fifth (p< 0.001) metatarsal heads. CONCLUSIONS: Using KT to correct a hallux valgus is a procedure that has an impact on the dynamic parameters of the foot during gait. The use of this method could become an alternative to surgical treatment for those patients, who have any contraindication for surgery.

Mid-term foot function and pedobarographic analysis of 52 feet after polydactyly resection in childhood.

AIMS: The aims of this study is to report the clinical and radiological outcomes after pre-, central-, and postaxial polydactyly resection in children from a tertiary referral centre. METHODS: All children who underwent resection of a supernumerary toe between 2001 and 2013 were prospectively enrolled and invited for a single re-assessment. Clinical parameters and several dedicated outcome scores (visual analogue scale (VAS), Paediatric Outcomes Data Collection Instrument (PODCI), Activities Scale for Kids (ASK), and American Orthopaedic Foot and Ankle Society Score (AOFAS)) were obtained, as were radiographs of the operated and non-operated feet along with pedobarographs. RESULTS: In all, 39 children (52 feet) with a mean follow-up of 7.2 years (3.1 to 13.0) were included in the study. Resection of a duplicated great toe was performed in ten children, central polydactyly in four, and postaxial polydactyly in 26. The mean postoperative VAS (0.7; 0 to 7), ASK (93.7; 64.2 to 100), and AOFAS range (85.9 to 89.0) indicated excellent outcomes among this cohort and the PODCI global functioning scale (95.7; 75.5 to 100) was satisfactory. No significant differences were found regarding outcomes of pre- versus postaxial patients, nor radiological toe alignment between the operated and non-operated sides. Minor complications were observed in six children (15%). There were seven surgical revisions (18%), six of whom were in preaxial patients. In both groups, below the operation area, a reduced mean and maximum force was observed. Changes in the hindfoot region were detected based on the prolonged contact time and reduced force in the preaxial group. CONCLUSION: Excellent mid-term results can be expected after foot polydactyly resection in childhood. However, parents and those who care for these children need to be counselled regarding the higher risk of subsequent revision surgery in the preaxial patients. Also, within the study period, the plantar pressure distribution below the operated part of the foot did not return to completely normal. Cite this article: Bone Joint J 2021;103-B(2):415-420.

[Anatomy of foot perforator veins in surgery of varicose veins]. / Anatomiya perforantnykh ven stopy v khirurgii varikoznoi bolezni.

OBJECTIVE: To clarify the role of clinical anatomy of foot and ankle perforator veins (PV) in surgical treatment of varicose vein disease. MATERIAL AND METHODS: Anatomy of foot and ankle PV was assessed in 50 amputated lower extremities by anatomical dissection. RESULTS: There were 4-6 PVs at the medial surface of the foot. These veins connected medial marginal vein and vv. plantaris medialis (VPM). There were 2-3 PVs at the lateral surface of the foot. These veins connected lateral marginal vein and vv. plantaris lateralis (VPL). All PVs on the lateral surface of the foot constitute the neurovascular bundles. PVs flowing into vv. dorsalis pedis are localized on the medial surface of the medial marginal vein at the level of the ankle base. In most cases, we found an arterial branch nearby at the subfascial level. In anterior part of the plantar surface of the foot, we distinguished 4-5 small PVs (~1 mm) flowing into vv. digitales plantares through the commissural orifices of the aponeurosis. There were 6-9 vessels (~1 mm) along the fascial aponeurotic septa. These vessels connected superficial plantar venous network and plantar veins. Small arterial branch was found almost in all cases near these veins. Noteworthy is the area where the plantar veins lie on the quadratus plantae and are covered by a leaf of deep plantar fascia. This anatomy is similar to topography of posterior tibial veins. CONCLUSION: Foot perforator veins constitute the neurovascular bundles as a rule. Plantar vein topography and their relationship with PV confirm an existence of muscular-venous pump of the foot.

Case Report: Coral Reef Pathogen Aspergillus sydowii Causing Black Grain Mycetoma.

Mycetoma is an infrequent subcutaneous infection caused by true fungi (eumycetoma) or aerobic actinomycetes (actinomycetoma). We report the case of a 62-year-old man with eumycetoma involving the left foot and ankle. Skin biopsy revealed black-brown grains, and in culture, a white colony fungus grew at day 8. Molecular sequencing using ITS1-ITS4 primers identified the species as Aspergillus sydowii. The patient was treated with itraconazole 200 mg twice daily and terbinafine 250 mg daily for 8 months, with complete response and no recurrence after 2.5 years of follow-up. Aspergillus sydowii is a saprotrophic fungus that rarely causes skin or nail disease. No cases of eumycetoma caused by this agent have been previously reported. As its geographic distribution continues to expand, it may increasingly be recognized as a cause of human disease.

Simultaneous bilateral hallux valgus surgery: Percutaneous or conventional? Early results of a matched study from a tertiary institution.

BACKGROUND: Hallux valgus is bilateral in up to 84 % of cases. In the setting of simultaneous bilateral correction, we aim to evaluate if minimally invasive percutaneous surgery (MIS) provides any advantage compared to conventional open surgery. METHODS: 52 feet (26 patients) undergoing simultaneous bilateral MIS surgery were matched by severity of deformity to 52 feet (26 patients) undergoing simultaneous conventional open surgery. Patients were followed for a minimum of six months. Pre- and post-operative radiographs and clinical records were reviewed. RESULTS: There were no significant differences in pre-operative function or pain between both groups. Post-operatively, the mean hallux valgus angle (HVA) was significantly lower in the MIS group. (HVA MIS - 8.6; Open - 11.8, P = 0.013). There were no significant differences in post-operative outcome and patient satisfaction between both groups. CONCLUSION: This study demonstrates that simultaneous bilateral MIS hallux valgus surgery can be considered for patients with bilateral symptomatic hallux valgus.

Effects of anodyne treatment on local blood flow and cutaneous sensation of the foot in a patient with peripheral neuropathy secondary to acromegaly.

Acromegaly is an excessive amount of serum growth hormone, which may present with sensorimotor polyneuropathy, affecting sensation and/or blood flow in the limbs. Symptoms include numbness, tingling or pain with impaired sensation including kinesthesia and proprioception. We report here of a 48-year-old male with a defined diagnosis of acromegaly and surgical excision of a pituitary adenoma 20 years ago. Recently he reports feet stepping on, and not feeling, objects under foot and balance problems starting 10 years ago. This study used a single-subject A-B-A design to show that behavioral changes are evident only in the presence of an intervention. Intervention consisted of Monochromatic Infrared Light Energy (MIRE), delivered by the Anodyne Therapy System (ATS). The DRT-4 laser Doppler measured red blood cell flux (flow), concentration and velocity. Levels of significance utilized the two standard deviation band method. Peripheral sensation of eight sites on each foot assessed using Semmes-Weinstein monofilaments (SWM) revealed a lack of sensation in the feet. A treatment effect as exhibited by blood flow velocity and red blood cell concentration was detected after the third week of treatment indicating peripheral dilation of the microvasculature. MIRE was an effective intervention for the treatment of acromegaly - induced polyneuropathy in this patient.

Trends and Technologies in Rehabilitation of Foot Drop: A Systematic Review.

INTRODUCTION: Foot Drop (FD) is a condition, which is very commonly found in post-stoke patients; however it can also be seen in patients with multiple sclerosis, and cerebral palsy. It is a sign of neuromuscular damage caused by the weakness of the muscles. There are various approaches of FD's rehabilitation, such as physiotherapy, surgery, and the use of technological devices. Recently, researchers have worked on developing various technologies to enhance assisting and rehabilitation of FD. AREAS COVERED: This review analyzes different types of technologies available for FD. This include devices that are available commercially or still under research. 101 studies published between 2015 and 2020 were identified for the review, many were excluded due to various reasons, e.g., were not robot-based devices, did not include FD as one of the targeted diseases, or was insufficient information. 24 studies that met our inclusion criteria were assessed. These studies were further classified into two different categories: robot-based ankle-foot orthosis (RAFO) and Functional Electrical Stimulation (FES) devices. EXPERT OPINION: Studies included showed that both RAFO and FES showed considerable improvement in the gait cycle of the patients. Future trends are inclining towards integrating FES with other neuro-concepts such as muscle-synergies for further developments.

Attenuation of carrageenan-induced hind paw edema and plasma TNF-α level by Philippine stingless bee (Tetragonula biroi Friese) propolis.

Despite decades-long existence of the Philippine stingless bee industry, the biological activity of propolis from this native bee species (Tetragonula biroi Friese) remains poorly understood and sparingly investigated. Herein, we examined the potential anti-inflammatory efficacy of Philippine stingless bee propolis using the lambda (λ)-carrageenan-induced mice model of hind paw edema. Thirty (30), six-week-old, male ICR mice were randomly assigned into three treatment groups (n=10/group) as follows: distilled water group, diclofenac sodium group (10 mg/kg), and propolis group (100 mg/kg). All treatment were administered an hour prior to the injection of the phlogistic agent. As observed at 3 h post-injection, λ-carrageenan remarkably evoked the classical signs of hind paw edema exemplified grossly by swelling and hyperemia. The ameliorative effect of propolis became apparent at the onset of 6 h post-injection with a statistically significant finding evident at the 24-h period. This gross attenuation histologically correlated to a considerable and specific reduction of the dermal edema, which mirrored those of the diclofenac sodium group. Furthermore, both propolis and diclofenac sodium significantly attenuated the λ-carrageenan-induced increase in the protein expression levels of the pro-inflammatory cytokine tumor necrosis factor-α (TNF-α) depicting more than two-fold decrement relative to the distilled water group. Altogether, these suggest that Philippine stingless bee propolis also exhibited a promising in vivo anti-inflammatory property, which can be partly mediated through the inhibition of TNF-α.
