Background

The provision of therapeutic footwear, to prevent the development of diabetic foot ulcers by re-distributing high peak plantar pressure is frequently prescribed for patients with diabetes. Areas of interest (ROI) are identified by placing boxes on the visualised pressure movie. The aims were to evaluate the inter-reliability of the placements of seven ROI boxes and to explore how the box placement affected peak pressure in the seven ROIs.

Methods

Plantar pressure movies from 20 of a total of 40 movies were selected for the analysis. Boxes were placed at ROIs, the heel, the lateral midfoot, the metatarsal phalangeal heads (5, 3–4, 2 and 1) and the hallux. The box placements were registered for the left vertical position (L) and the top horizontal position (T) for each of the ROIs, based on registrations by two certified prosthetists and orthotists.

Findings

The inter correlation coefficient of the placement of the boxes ranged from 1.00 to 0.12 (heel_L and metatarsal phalangeal head 2_L respectively). Of the 14 positions of the boxes; four were excellent, four were good, two were moderate and four were poor. No significant differences in the mean peak pressure corresponding to the box placements were found between the CPOs.

Interpretation

The inter-reliability of eight of the 14 registered placements, made by prosthetists and orthotists, of the boxes in Scan® was good to excellent. A variation of 1.00–0.12 was present. Despite the variation, no significant differences in the corresponding mean peak pressure between prosthetists and orthotists was found.

Introduction

Chronic ankle instability (CAI) is a disorder that occurs after one or more acute ankle sprains and is characterised by persistent symptoms which include episodes of ‘‘giving way’’ a sensation of instability, recurrent ankle sprains, and functional deficits. Despite of effective treatment strategies a comprehensive approach is needed that can break this continuum of disability and improve the postural control. A systematic review with meta-analysis assessing the effectiveness of interventions targeting plantar cutaneous receptors for improving postural control in individuals with chronic ankle instability.

Methods

The systematic review with meta-analysis was performed following PRISMA guidelines. Outcome measure used to evaluate the improvement in which static postural control was assessed on SLBT (Single limb balance test) and COP (Centre of pressure) whereas dynamic postural control was assessed on SEBT (star excursion balance test) and scores expressed as mean ± SD and random-effects model were performed, and heterogeneity between the studies was calculated using the I² statistic.

Results

A total of 168 CAI populations were included among the 8 selected studies in the meta-analysis. In which,5 studies using Plantar massage and 3 studies using foot insole were assessed, with moderate to high quality on the Pedro scale (range 4–7). For single and six-sessions of plantar massage showed insignificant effect on SLBT COP and for the single session of custom moulded FO showed insignificant effect on SEBT.

Conclusion

The meta-analysis showed non-significant pooled results for plantar massage and foot orthotics on static and dynamic postural control when assessed on postural outcome measures. Further high-quality evidence-based trials would be required to highlight the importance of sensory targeted approaches to treat the postural instability in CAI patients.

Background

Even after corrective casting and bracing, clubfoot recurrence is challenging throughout childhood, with around 14–40 % recurrence rates. Most of the literature on recurrence was attributed to various factors, and minimal research was conducted to know the role of foot evertor muscle activity and its stimulation benefits. This study aimed to assess the role of foot evertor muscle activity in idiopathic congenital clubfoot recurrence by using clinical, sonographic, and electromyographic parameters.

Methods

A prospective cohort study was conducted at our tertiary care hospital from 2020 to 2022. The patient’s demographic data, Pirani, Dimeglio, Clinical Evertor Muscle Activity scores, sonographic cross-sectional areas of leg muscle, and evertor motor activity using surface electromyography were recorded in adherence to the pre-defined intervals.

Results

In total, 51 patients (51 feet) were included in the study, and the overall recurrence rate was 27.5 % (14/51). In this study, around 47 % (24/51) of children had mild or poor clinical evertor activity; among them, 58 % (14/24) children had a recurrence, and the insufficient clinical evertor activity and recurrence were strongly correlated (p = 0.01). Evertor muscle cross-sectional area ratio, motor unit potentials, and recruitment were comparatively less in the recurred group; however, only the cross-sectional area ratio was statistically significant (p = 0.02).

Conclusion

Early detection of evertor muscle weakness can help to individualize the treatment plans by predicting recurrence. Therefore, it should be included in routine clinical evaluations. Further research is required to determine the advantages of evertor muscle-strengthening activities in preventing idiopathic clubfoot deformity.

Level of Clinical Evidence

A prospective cohort study, Level of evidence-II

Pressure measurement systems have numerous applications in healthcare and sport. The purpose of this review is to: (a) describe the brief history of the development of pressure sensors for clinical and sport applications, (b) discuss the design requirements for pressure measurement systems for different applications, (c) critique the suitability, reliability, and validity of commercial pressure measurement systems, and (d) suggest future directions for the development of pressure measurements systems in this area. Commercial pressure measurement systems generally use capacitive or resistive sensors, and typically capacitive sensors have been reported to be more valid and reliable than resistive sensors for prolonged use. It is important to acknowledge, however, that the selection of sensors is contingent upon the specific application requirements. Recent improvements in sensor and wireless technology and computational power have resulted in systems that have higher sensor density and sampling frequency with improved usability – thinner, lighter platforms, some of which are wireless, and reduced the obtrusiveness of in-shoe systems due to wireless data transmission and smaller data-logger and control units. Future developments of pressure sensors should focus on the design of systems that can measure or accurately predict shear stresses in conjunction with pressure, as it is thought the combination of both contributes to the development of pressure ulcers and diabetic plantar ulcers. The focus for the development of in-shoe pressure measurement systems is to minimise any potential interference to the patient or athlete, and to reduce power consumption of the wireless systems to improve the battery life, so these systems can be used to monitor daily activity. A potential solution to reduce the obtrusiveness of in-shoe systems include thin flexible pressure sensors which can be incorporated into socks. Although some experimental systems are available further work is needed to improve their validity and reliability.

Aim

This study aimed to investigate the clinical efficacy of externally applied Traditional Chinese Medicine (TCM) on diabetic foot.

Methods

We searched the China Knowledge Network (CNKI), Wanfang Database, PubMed and Web of Science from inception to July 31, 2022, to find all randomized control trials (RCTs) related to externally applied TCMs in diabetic foot treatment. Information about the total effective rate, healing rate, and healing time were extracted. In addition, the relative risk (RR)/odds ratio (OR) or standardized mean difference (SMD) and 95 % confidence interval (CI) were calculated.

Results

Finally, a total of 34 RCTs including 3758 patients were included in this meta-analysis. There were 5 articles that reported hydropathic compress with astrogalin, 14 articles that reported MEBO burn cream, 9 articles that reported compound cortex phellodendri liquid and 6 articles that reported Shengji Yuhong ointment. Compared with the basic treatment, the externally applied TCM (astrogalin, MEBO burn cream, compound cortex phellodendri liquid and Shengji Yuhong ointment) combined with basic treatment improved the total effective rate (RR = 1.31 [1.20, 1.42], P < 0.0001) and healing rate (RR = 1.84 [1.56, 2.17], P < 0.0001) and shortened the healing time (SMD = − 2.51 [− 3.39, − 1.63], P < 0.0001).

Conclusion

Our systematic review and meta-analysis revealed that common TCM applied externally could significantly improve the clinical efficacy comparing to the basic treatment.

The etiology of plantar heel pain is multifactorial. Myofascial trigger points of abductor hallucis muscle one of the muscles that should be carefully evaluated and treated in patients diagnosed with plantar fasciitis.

Background

Abnormal kinematics and kinetics in the lower extremity during gait may be improved by modulating the center of force trajectory of the foot. This study aimed to confirm whether short-interval training using plastic hemispherical protruding stickers (diameter: 5 mm; height: 2 mm) attached to the plantar surface of the foot to enhance plantar sensory feedback can help actively control the center of force trajectory during gait.

Methods

Twenty healthy female subjects underwent three-dimensional barefoot gait analysis under control conditions and two post-training conditions. Before the measurements under post-training conditions, the subjects underwent a 5-minute training to control the center of force trajectory with two protruding stickers attached to the plantar surface of the right foot. During training, the subjects were asked to put their weight on the stickers. The attachment positions of the stickers were the heel and either the first or fifth metatarsal head, which was randomly determined although both were tested.

Results

The center of pressure trajectory during the right stance phase of the gait shifted in the direction of the protruding stickers attached in the last training, although the stickers had already been removed.

Conclusions

The study results confirmed that a 5-minute training with protruding stickers attached to the plantar surface of the foot can help actively control the center of pressure trajectory during gait.

Objective

This study aimed to determine whether the prolonged duration of diabetic foot ulcers was associated with an increased incidence of diabetic foot osteomyelitis.

Study design

A retrospective cohort study

Methods

The medical records of all patients who participated in the diabetic foot clinic between January 2015 and December 2020 were reviewed. Patients with new diabetic foot ulcers were monitored for diabetic foot osteomyelitis. The collected data included the patient’s profile, comorbidities and complications, the ulcer profile (area, depth, location, duration, number of ulcers, inflammation, and history of the previous ulcer), and outcome. Univariate and multivariate Poisson regression analyses were used to assess risk variables for diabetic foot osteomyelitis.

Results

Eight hundred and fifty-five patients were enrolled; 78 developed diabetic foot ulcers (cumulative incidence 9% over 6 years, average annual incidence 1.5%) and among these diabetic foot ulcers, 24 developed diabetic foot osteomyelitis (cumulative incidence 30% over 6 years, average annual incidence of 5%, incidence rate 0.1/person-year). Statistically significant risk factors for the development of diabetic foot osteomyelitis were ulcers that were deep to the bone (adjusted risk ratio 2.50, p = 0.04) and inflamed wounds (adjusted risk ratio 6.20, p = 0.02). The duration of diabetic foot ulcers was not associated with diabetic foot osteomyelitis (adjusted risk ratio 1.00, p = 0.98).

Conclusion

The duration was not an associated risk factor for diabetic foot osteomyelitis, while bone-deep ulcers and inflamed ulcers were found to be significant risk factors for the development of diabetic foot osteomyelitis.

Introduction

Healing of Diabetic Foot ulcer is crucial to prevent amputation. Offloading is key treatment of diabetic foot ulcers, but choosing which offloading modality is still not clear. Besides, other factors that control ulcer healing, is a question that needs to be determined. Objective: to assess factors that affect ulcer healing, comparing two commonly used offloading devices, removable walker and cast-shoe.

Methods

This is a Randomized Clinical Trial which recruited 87 patients with active diabetic foot ulcers randomly assigned to either a removable walker (W-arm) or a cast-shoe (C-arm) at 3:2 ratio. Both groups received the routine ulcer care, and were followed-up for 24 weeks. Different possible factors related to healing were assessed, and a regression model was built for the most predictive factors.

Results

The 24-week healing rate was 81% for the walker group and 62 % for the cast-shoe group. The mean adherence was 55 % ± 26 % and 46 % ± 29 for the walker and cast shoe groups respectively. Ulcer healing was significantly positively associated with: better adherence, device type (walker), less SINBAD score (2 or less), absence of ischemia, absence of infection, smaller ulcer area, superficial ulcer, better 4-week area reduction, and better blood glucose control. The most important predictors were adherence, total SINBAD score and 4-week area reduction.

Conclusion

SINBAD score at initial presentation and the degree of adherence to offloading device, are two major determinants of ulcer healing. Ulcer area reduction at 4 weeks represents an important clinical parameter to predict and guide the success of ulcer management.

Purpose

Subtalar arthroereisis is a minimally-invasive technique for the treatment of flexible flatfoot. Some issues regarding the procedure are still debated, such as post-operative management. The aim of this study is to offer a review of the pertaining literature to identify current post-operative protocols and describe possible differences among them.

Methods

We searched the PubMed database for all papers related to subtalar arthroereisis in children specifying the post-operative protocols. After reviewing all studies according to excluding criteria, 50 articles were selected for analysis.

Results

Based on the literature review, different post-operative protocols emerged in the treatment of patients undergoing subtalar arthroereisis, in particular regarding length of hospital stay, type and duration of immobilization, weight-bearing management, adopted rehabilitation scheme, sport resumption and implant removal.

Conclusions

The most important finding was the existence of a wide variety in post-operative management after subtalar arthroereisis in children, thus confirming that no clear consensus still exists in this field.
