The effects of vibrating shoe insoles on standing balance, walking, and ankle-foot muscle activity in adults with diabetic peripheral neuropathy. Gait Posture 2024; 111:8-13. [PMID: 38603968 DOI: 10.1016/j.gaitpost.2024.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Revised: 04/07/2024] [Accepted: 04/08/2024] [Indexed: 04/13/2024]
Abstract
BACKGROUND Peripheral neuropathy is one of the most common complications of type 2 diabetes, which can lead to impaired balance and walking. Innovative footwear devices designed to stimulate foot sensory receptors, such as vibrating insoles, could offer a new route to improve motor impairments in people with diabetic peripheral neuropathy (DPN). RESEARCH QUESTION Does wearing vibrating insoles for the first time alter measures of balance, walking, and ankle-foot muscle activity, in people with DPN? METHODS A randomised cross-over study was conducted with 18 ambulant men and women with a diagnosis of DPN. Participants performed tests of standing balance (Bertec® force platform) under four conditions (foam/firm surface, eyes open/closed) and level-ground walking (GAITRite® instrumented walkway), whilst wearing vibrating and non-vibrating (control) insoles on two separate occasions (one insole/session). Electromyography (EMG) was used to assess soleus, medial gastrocnemius, tibialis anterior, peroneus longus activity during balance tests. Outcomes included centre of pressure (CoP) sway, EMG amplitude, spatiotemporal gait patterns, and Timed Up and Go test. One sample t-tests were used to explore %differences in outcomes between insole conditions. RESULTS Wearing vibrating insoles led to a reduction (improvement) in CoP elliptical area, when standing on a foam surface with eyes closed, relative to non-vibrating insoles (P=0.03). Applying perceptible vibrations to the soles of the feet also reduced the EMG amplitude in soleus (P=0.01 and P=0.04) and medial gastrocnemius (P=0.03 and P=0.09) when standing with eyes closed on firm and foam surfaces. SIGNIFICANCE Our findings of signs of improved balance and altered muscle activity with suprasensory vibrating insoles provides new insights into how these devices can be used to inform innovative rehabilitation approaches in individuals with DPN. This will be strengthened by further research into possible clinical benefits of these devices - given that the effects we detected were small with uncertain clinical meaning.

Study protocol for a randomized controlled trial on the effect of the Diabetic Foot Guidance System (SOPeD) for the prevention and treatment of foot musculoskeletal dysfunctions in people with diabetic neuropathy: the FOotCAre (FOCA) trial I. Trials 2020; 21:73. [PMID: 31931855 PMCID: PMC6958734 DOI: 10.1186/s13063-019-4017-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Accepted: 12/19/2019] [Indexed: 01/29/2023] Open
Abstract
BACKGROUND This study is part of a series of two clinical trials. Taking into account the various musculoskeletal alterations of the foot and ankle in people with diabetic peripheral neuropathy (DPN) and the need for self-care to avoid more serious dysfunctions and complications, a self-manageable exercise protocol that focuses on strengthening the foot muscles is presented as a potentially effective preventive method for foot and gait complications. The aim of this trial is to investigate the effect of a customized rehabilitation technology, the Diabetic Foot Guidance System (SOPeD), on DPN status, functional outcomes and gait biomechanics in people with DPN. METHODS/DESIGN Footcare (FOCA) trial I is a randomized, controlled and parallel two-arm trial with blind assessment. A total of 62 patients with DPN will be allocated into either a control group (recommended foot care by international consensus with no foot exercises) or an intervention group (who will perform exercises through SOPeD at home three times a week for 12 weeks). The exercise program will be customized throughout its course by a perceived effort scale reported by the participant after completion of each exercise. The participants will be assessed at three different times (baseline, completion at 12 weeks, and follow-up at 24 weeks) for all outcomes. The primary outcomes will be DPN symptoms and severity classification. The secondary outcomes will be foot-ankle kinematics and kinetic and plantar pressure distribution during gait, tactile and vibration sensitivities, foot health and functionality, foot strength, and functional balance. DISCUSSION As there is no evidence about the efficacy of rehabilitation technology in reducing DPN symptoms and severity or improving biomechanical, clinical, and functional outcomes for people with DPN, this research can contribute substantially to clarifying the therapeutic merits of software interventions. We hope that the use of our application for people with DPN complications will reduce or attenuate the deficits caused by DPN. This rehabilitation technology is freely available, and we intend to introduce it into the public health system in Brazil after demonstrating its effectiveness. TRIAL REGISTRATION ClinicalTrials.gov, NCT04011267. Registered on 8 July 2019.

Abstract
Uncontrolled high blood sugar levels leads to diabetic neuropathy, which is usually develops slowly. Damaged nerves stop sending messages or may send message slowly at the wrong times. The propsed model is an insole for individuals with peripheral neuropathy conditions, where the peak plantar pressure value is measured at specified locations of the foot by means of a pressure sensor, which can be accessed via a mobile applications; Simultaneously, a stimulation is given at acupressure points of the foot to relieve pain at definite intervals of time, based on the signals from the controller. A controller is being used to perform these operations which will be transmitted to the mobile application via Bluetooth terminal.

Abstract
BACKGROUND peripheral neuropathy is known as one of most common complication in diabetes mellitus type 2 patient. This complication is caused by uncontrolled condition of blood glucose level in long periode. Regular physical activity in moderate to high intensity is beneficial in management of diabetes mellitus. This report aimed to know the effectiveness of aerobic exercise in causing improved peripheral functions in type 2 diabetes mellitus. METHODS literature searching using several related keywords in Medline®, Pubmed®, and Cochrane library, following inclusion and exclusion criteria. RESULTS Dixit et al suggested that a heart rate intensity of 40-60% aerobic exercise of 30-45 min duration per session for eight weeks suggest an important impact in controlling diabetic peripheral neuropathy. Kluding PM et al suggested that significantly improved selected measures of peripheral nerve function ("worst" pain levels and MNSI score), glycemic control (HbA1c), and resting heart rate. CONCLUSION the studies showed significant benefit of aerobic exercise, despite the short duration of exercise being used as intervention towards improvement in peripheral nerve function. However, further studies with large samples and longer duration of intervention are needed to confirm the finding.

Lower-extremity dynamics of walking in neuropathic diabetic patients who wear a forefoot-offloading shoe. Clin Biomech (Bristol, Avon) 2017; 50:21-26. [PMID: 28985487 DOI: 10.1016/j.clinbiomech.2017.10.003] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2016] [Revised: 09/13/2017] [Accepted: 10/01/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND A forefoot-offloading shoes has a negative-heel rocker outsole and is used to treat diabetic plantar forefoot ulcers, but its mechanisms of action and their association with offloading and gait stability are not sufficiently clear. METHODS Ten neuropathic diabetic patients were tested in a forefoot-offloading shoe and subsequently in a control shoe with no specific offloading construction, both worn on the right foot (control shoe on left), while walking at 1.2m/s. 3D-instrumented gait analysis and simultaneous in-shoe plantar pressure measurements were used to explain the shoe's offloading efficacy and to define centre-of-pressure profiles and left-to-right symmetry in ankle joint dynamics (0-1, 1:maximum symmetry), as indicators for gait stability. FINDINGS Compared to the control shoe, peak forefoot pressures, vertical ground reaction force, plantar flexion angle, and ankle joint moment, all in terminal stance, and the proximal-to-distal centre-of-pressure trajectory were significantly reduced in the forefoot-offloading shoe (P<0.01). Peak ankle joint power was 51% lower in the forefoot-offloading shoe compared to the control shoe: 1.61 (0.35) versus 3.30 (0.84) W/kg (mean (SD), P<0.001), and was significantly associated with forefoot peak pressure (R2=0.72, P<0.001). Left-to-right symmetry in the forefoot-offloading shoe was 0.39 for peak ankle joint power. INTERPRETATION By virtue to their negative-heel rocker-outsole design, forefoot-offloading shoes significantly alter a neuropathic diabetic patient's gait towards a reduced push-off power that explains the shoe's offloading efficacy. However, gait symmetry and stability are compromised, and may be factors in the low perceived walking discomfort and limited use of these shoes in clinical practice. Shoe modifications (e.g. less negative heel, a more cushioning insole) may resolve this trade-off between efficacy and usability.

Abstract
BACKGROUND The number of diabetic patients is increasing in the world. Peripheral neuropathy is the most important problem of diabetes. Neuropathy eventually leads to balance impairment which is the main cause of falling down in these patients However, not sufficient evidences available to compare different protocols for improving balance in diabetic patients. OBJECTIVE This study aimed to compare the effects of two therapeutic exercises on clinical balance measures in patients with type II diabetic peripheral neuropathy. METHODS The study was performed on 60 patients with diabetes categorized randomly into three groups: an intervention group (N=20) that received ball training exercise, another intervention group (N=20) that received Frenkel exercise and a control group (N=20) that received no interventions. Exercise training session was performed for 3 weeks. Then, clinical balance measures were computed in the three groups. Paired t-test and one-way ANOVA were used to analyze the collected data. RESULTS Both types of therapeutic exercise programs significantly improved balance in single leg stance, star excursion test, and Berg balance scale test (P˂0.05) compared to the control group. Besides, this was more significant in the ball training group (P˂0.05). CONCLUSIONS To improve balance in diabetic neuropathy, Swiss ball exercise is preferred compared to Frenkel training.

Abstract
Purpose Painful diabetic neuropathy (PDN) has a significant impact on patients’ quality of life, affecting sleep, mood, mobility, ability to work, interpersonal relationships, overall self-worth, and independence. The purpose of this article is to provide diabetes educators with current and essential tools for PDN assessment and management. Methods Medline and CINAHL database searches identified publications on the assessment and treatment of PDN. Identified research was evaluated, and information pertinent to diabetes educators was summarized. Results Recent advancements in assessment of neuropathic pain include identifying characteristics that distinguish between neuropathic and nonneuropathic pain. In the absence of treatment, research demonstrates that nerve damage may progress while pain diminishes. Many disease-modifying and symptom-management treatment options are available. Conclusion Good glycemic control is the first priority for both prevention and management of PDN. However, even with good glycemic control, up to 20% of patients will develop PDN. PDN recognition and assessment are critical to optimize management. Although several treatment modalities are available, few patients obtain complete pain relief. Recent advances in understanding the mechanisms underlying neuropathic pain should lead to better treatment and patient outcomes. Combination therapy, including nonpharmacologic modalities, may be required. Research evaluating the efficacy of combination therapy is needed.

Surgical management of Charcot neuroarthropathy of the ankle and hindfoot in patients with diabetes. Diabetes Metab Res Rev 2016; 32 Suppl 1:292-6. [PMID: 26452590 DOI: 10.1002/dmrr.2748] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2015] [Revised: 07/06/2015] [Accepted: 10/06/2015] [Indexed: 11/07/2022]
Abstract
BACKGROUND Charcot neuroarthropathy (CN) of the ankle and hindfoot (Sanders/Frykberg Type IV) is challenging to treat surgically or nonsurgically. The deformities associated with ankle/hindfoot CN are often multiplanar, resulting in sagittal, frontal and rotational malalignment. In addition, shortening of the limb often occurs from collapse of the distal tibia, talus and calcaneus. These deformities also result in significant alterations in the biomechanics of the foot. For example, a varus ankle/hindfoot results in increased lateral column plantar pressure of the foot, predisposing the patient to lateral foot ulceration. Collapse of the talus, secondary to avascular necrosis or neuropathic fracture, further accentuates these deformities and contributes to a limb-length inequality. SURGICAL MANAGEMENT The primary indication for surgical reconstruction is a nonbraceable deformity associated with instability. Other indications include impending ulceration, inability to heal an ulcer, recurrent ulcers, presence of osteomyelitis and/or significant pain. Arthrodesis of the ankle and/or hindfoot is the method of choice when surgically correcting CN deformities in this region. The choice of fixation (i.e. internal or external fixation) depends on largely on the presence or absence of active infection and bone quality. CONCLUSION Surgical reconstruction of ankle and hindfoot CN is associated with a high rate of infectious and noninfectious complications. Despite this high complication rate, surgeons embarking on surgical reconstruction of ankle and hindfoot CN should strive for limb salvage rates approximating 90%. Preoperative measures that can improve outcomes include assessment of vascular status, optimization of glycemic control, correction of vitamin D deficiency and cessation of tobacco use.

From treatment to preventive actions: improving function in patients with diabetic polyneuropathy. Diabetes Metab Res Rev 2016; 32 Suppl 1:206-12.

Abstract
Diabetic polyneuropathy is an insidious and long-term complication of this disease. Synergistic treatments and preventive actions are crucial because there are no clear boundaries for determining when health professionals should intervene or what intervention would best avoid the consequences of neuropathy. Until now, most therapies to any diabetic individual were applied only after the patient's limb was ulcerated or amputated. The loss of muscle and joint functions is recognized as the main cause of plantar overloading. However, if foot and ankle exercises are performed following the early diagnosis of diabetes, they can enable the patient to maintain sufficient residual function to interact with the environment. This article summarizes the current knowledge about the musculoskeletal deficits and biomechanical alterations caused by neuropathy. It also describes the potential benefits of foot and ankle exercises for any diabetic patient that is not undergoing the plantar ulcer healing process. We concentrate on the prevention of the long-term deficits of neuropathy. We also discuss the main strategies and protocols of therapeutic exercises for joints and muscles with deficits, which are applicable to all diabetic patients with mild to moderate neuropathy. We describe further efforts in exploiting the applicability of assistive technologies to improve the adherence to an exercise program. Following the contemporary trends towards self-monitoring and self-care, we developed a software to monitor and promote personalized exercises with the aim of improving autonomous performance in daily living tasks. Initiatives to prevent the complications of functional diabetes are highly recommended before it is too late for the patient and there is no longer an opportunity to reverse the tragic consequences of neuropathy progression.

Abstract
With the increased number of diabetics worldwide and the increased incidence of morbid obesity in more prosperous cultures, there has become an increased awareness of Charcot arthropathy of the foot and ankle. Outcome studies would suggest that patients with deformity associated with Charcot Foot arthropathy have impaired health related quality of life. This awareness has led reconstructive-minded foot and ankle surgeons to develop surgical strategies to treat these acquired deformities. This article outlines the current clinical approach to this disabling medical condition.

Abstract
OBJECTIVE To investigate the effect of combination therapy of backward walking training and alpha-lipoic acid (ALA) treatment on the distribution of plantar pressure in patients with diabetic peripheral neuropathy (DPN). DESIGN This study is a double-blinded, randomized controlled trial. The test group was treated with combination therapy of backward walking exercise and ALA (ALA for 2wk, backward walking exercise for 12wk), and the control group only received ALA treatment. SETTING Clinical and laboratory setting. PARTICIPANTS Patients with DPN (N=60) were divided into the test group (n=30) or control group (n=30). INTERVENTIONS Backward walking exercise with ALA treatment for the test group; lipoic acid treatment for the control group. MAIN OUTCOME MEASURE Plantar pressure before and after treatment was tested and analyzed with the flatbed plantar pressure measurement system. RESULTS After treatment, peak plantar pressure in the forefoot dropped for both the test and control groups; peak plantar pressure for the test group dropped significantly. Peak plantar pressure in the medial foot slightly increased for the test group, suggesting a more even distribution of plantar pressure in the test group after treatment. CONCLUSIONS The combination therapy of ALA and backward walking proved to be more effective than ALA monotherapy. Backward walking also proved to have an ameliorating effect on balance ability and muscle strength of patients with DPN.

Abstract
OBJECTIVE Recent literature on acute diabetic Charcot osteoarthropathy (CA) reports unusually long periods of off-loading. Data suggest that this might increase the re-currence rate. Subsequently we evaluated the influence of duration of off-loading on the risk of required re-casting. RESEARCH DESIGN AND METHODS In this retrospective consecutive series from 2000 to 2005, 56 people with diabetes and an acute Charcot foot were included. The inclusion criteria were an initial persistent temperature difference more than 2°C between the two feet, oedema, and typical hot spots on a bone scintigram, radiology, and a typical clinical course. Treatment was off-loading in a removable cast and 2 crutches. In-door walking was allowed. Gradually augmented weight bearing was prescribed when the skin temperature difference had decreased to a level less than 2°C and edema had subsided. Re-casting was required for immediate exacerbation during re-load as well as for recurrence - defined as new swelling and skin temperature difference of more than 2°C in the same foot occurring after a stable interval of at least one month after full weight bearing. RESULTS The duration of off-loading for all patients was 141±21 days (mean±SD). Three patients (5%) were re-casted immediately for exacerbation after re-load and 7 patients (12 %) after recurrence of the CA. Duration of re-casting was 79±44 days. The primary period of off-loading was not statistically significantly different for those not requiring versus those requiring re-casting: 142±24 days compared to 134±41 days. Neither were the differences in demographic data, metabolic regulation, BMI or localization of CA. CONCLUSIONS Patients with risk of exacerbation or recurrence of CA could not be identified in the present study and there was no relation to the duration of off-loading. Nevertheless off-loading periods with immobilisation should be kept as short as possible, due to other side effects. This can be obtained by early gradual augmented re-loading.

Abstract
Since 2000, there has been an ongoing debate regarding tightness of glycemic control in critically ill patients. An increased risk of hypoglycemia is observed in patients treated with an intensive insulin protocol targeting "normoglycemia," probably accounting for a reduction of the overall benefit. Hypoglycemia is associated with neurological side effects and is found to be an independent predictor of mortality in most trials; however, long-term sequelae are rare if glucose is administered early. We describe a case of prolonged, extreme hypoglycemia in a critically ill patient treated according to an intensive insulin protocol who recovered without any neurological deficit at discharge.

Abstract
Clinical observations provided evidence of the positive effects of multichannel electrical stimulation by bipolar pulsed currents in combination with galanthamine electrophoresis applied for the treatment of patients with complicated diabetes mellitus. Such treatment facilitated normalization of water and carbohydrate metabolism and reduction of the body weight; moreover, it improved blood circulation and the state of the nervous system.

Abstract
AIMS To investigate the feasibility and preliminary effectiveness of an exercise programme for patients with diabetic complications. METHODS In this pre-post design study, 22 patients from a diabetic foot outpatient clinic participated in a 12-week individualized exercise programme, consisting of aerobic and resistance exercise, with specific safety precautions. Feasibility was assessed on the basis of programme adherence, adverse events, achievement of the target training intensity and patient satisfaction. Preliminary effectiveness was evaluated with pre-post-changes in blood glucose regulation (HbA(1c) ), muscle strength (isometric peak torque) and perceived limitations in functioning (Patient Specific Function Scale with visual analogue scale). RESULTS Twenty patients completed the exercise programme with a high mean attendance (85%). No training-related severe adverse events occurred. The target training intensity was achieved by 70% of the participants. Patient satisfaction was high. HbA(1c) decreased from 8.2% before to 7.8% after the programme (P=0.005), muscle strength increased from 136.4 to 150.4 Nm (P = 0.046) and perceived limitations in functioning decreased from 7.2 to 5.8 mm (P=0.003). CONCLUSIONS The prescribed exercise programme had a potentially positive effect on blood glucose regulation, muscle strength and perceived limitations in functioning in patients with diabetic complications.

AIMS/HYPOTHESIS Gait characteristics and balance are altered in diabetic patients. Little is known about possible treatment strategies. This study evaluates the effect of a specific training programme on gait and balance of diabetic patients. METHODS This was a randomised controlled trial (n=71) with an intervention (n=35) and control group (n=36). The intervention consisted of physiotherapeutic group training including gait and balance exercises with function-orientated strengthening (twice weekly over 12 weeks). Controls received no treatment. Individuals were allocated to the groups in a central office. Gait, balance, fear of falls, muscle strength and joint mobility were measured at baseline, after intervention and at 6-month follow-up. RESULTS The trial is closed to recruitment and follow-up. After training, the intervention group increased habitual walking speed by 0.149 m/s (p<0.001) compared with the control group. Patients in the intervention group also significantly improved their balance (time to walk over a beam, balance index recorded on Biodex balance system), their performance-oriented mobility, their degree of concern about falling, their hip and ankle plantar flexor strength, and their hip flexion mobility compared with the control group. After 6 months, all these variables remained significant except for the Biodex sway index and ankle plantar flexor strength. Two patients developed pain in their Achilles tendon: the progression for two related exercises was slowed down. CONCLUSIONS/INTERPRETATION Specific training can improve gait speed, balance, muscle strength and joint mobility in diabetic patients. Further studies are needed to explore the influence of these improvements on the number of reported falls, patients' physical activity levels and quality of life.

Abstract
AIMS The recurrence of foot ulcers is a significant problem in people with diabetic neuropathy. The purpose of this study was to measure in-shoe plantar pressures and other characteristics in a group of neuropathic patients with diabetes who had prior foot ulcers which had remained healed. METHODS This was an epidemiological cohort study of patients from diabetes clinics of two Swedish hospitals. From a database of 2625 eligible patients, 190 surviving patients with prior plantar ulcers of the forefoot (hallux or metatarsal heads) caused by repetitive stress were identified and 49 patients agreed to participate. Barefoot and in-shoe plantar pressures were measured during walking. Data on foot deformity, activity profiles and self-reported behaviour were also collected. RESULTS Mean barefoot plantar peak pressure at the prior ulcer site (556 kPa) was lower than in other published series, although the range was large (107-1192 kPa). Mean in-shoe peak pressure at this location averaged 207 kPa when measured with an insole sensor. Barefoot peak pressure only predicted approximately 35% of the variance of in-shoe peak pressure, indicating variation in the efficacy of the individual footwear prescriptions (primarily extra-depth shoes with custom insoles). CONCLUSIONS We propose that the mean value for in-shoe pressures reported in these patients be used as a target in footwear prescription for patients with prior ulcers. Although plantar pressure is only one factor in a multifaceted strategy to prevent ulcer recurrence, the quantitative focus on pressure reduction in footwear is likely to have beneficial effects.

Abstract
About 60 to 70 percent of people with diabetes have some neuropathy. Diabetic neuropathy can be classified as peripheral, autonomic, proximal, focal and multifocal or mixed. Peripheral neuropathy, the most common type of diabetic neuropathy, causes pain and/or loss of feeling in the toes, feet, legs, hands, and arms; extreme sensitivity to touch, loss of balance and coordination; muscle weakness and loss of reflexes, especially at the ankle, leading to changes in the way a person walks. The aim of this study is to underline the importance of drug and rehabilitative approach in the therapy of peripheral neuropathy, that frequently influences both diabetes mellitus type 1 and diabetes mellitus type 2.

Abstract
OBJECTIVE This study was performed to identify the relationship between the quality of life and polyneuropathy which is one of the complications of diabetes. METHODS Total 111 patients with diabetes mellitus were taken into the study as type 1 and type 2. Patients were accepted having polyneuropathy according to their electroneuromyography (ENMG) results. To evaluate the quality of life in the patients Short Form 36 (SF-36) and World Health Organization Quality of Life Questionnaire abbreviated version (WHOQOL-BREF) were used. RESULTS Clinical polyneuropathy was found in 46% of the patients, while polineuropathy was found in 63% of the patients with evaluation ENMG. The patients with polyneuropathy had poor quality of life according to SF-36 and WHOQOL-BREF (p < 0.001). The mean quality of life scores of patients who had sensoriomotor and mix polyneuropathy, were lower than sensory type and axonal polyneuropathy. CONCLUSION Diabetic polyneuropathy influences the quality of life in a negative way. The quality of life scores of patients who had polyneuropathy continuing with mixed pathogenesis and sensoriomotor type, become worse for this reason, even if the patients do not have any clinical polyneuropathy, this being evaluated with ENMG.

Abstract
This study investigated the effects on standing balance of random vibrations applied to the plantar side of the feet by vibrating insoles in subjects with neuropathy and nondisabled subjects. In four different conditions (eyes open or closed and with or without an attention-demanding task [ATD]), subjects with neuropathy secondary to diabetes mellitus (n = 17) and nondisabled subjects (n = 15) stood for 60 s on vibrating insoles placed on a force plate. During each condition, the insoles were turned on for 30 s and off for 30 s (random order). The calculated balance measures were mean velocity of the center of pressure displacements and root-mean-square of the velocity of these displacements in the anteroposterior and mediolateral directions. In subjects with neuropathy, an interaction effect between vibration and an ADT was found for balance. No effects of vibration on balance were found in nondisabled subjects. Vibrating insoles improved standing balance in subjects with neuropathy only when attention was distracted. Improvement of the insoles and their activation is needed to make their implementation in daily living possible and effective.

Abstract
Patients with diabetes and chronic neurological disorders are most commonly "at-risk" with foot problems. The identification of that population is therefore mandatory to prevent severe foot lesions. However, not all health care providers (HCPs) are involved in the screening process in institutions. The authors' aim was to develop and evaluate an educational program for HCP in the field of at-risk foot. All HCPs of the Loëx Hospital (Department of Rehabilitation and Geriatrics, University Hospitals of Geneva) participated in a longitudinal prospective study. Different professions of HCP (doctors, nurses, nursing aides, physiotherapists, occupational therapists, speech-language therapists, and psychologists) attended a structured educational program during a 1-year period based on a specific consultation that the authors developed. During the sessions, risk factors and therapeutic and preventive interventions are discussed with both the patient and care givers. A questionnaire was developed and used to evaluate (1) initial knowledge of HCP in the field of at-risk foot and (2) the impact of the program on the knowledge of HCP 12 months after starting the program. Twelve months after initiating the program, a significant knowledge improvement was noted in all groups of HCP except medical doctors. Nurses presented the most significant rise in knowledge score (P < .001). In conclusion, the consultation is an acceptable and effective form of long-term educational program for HCP in a hospital setting with a huge majority of patients suffering from chronic vascular and neurological conditions and loss of protective pain sensation at the lower limb.

Abstract
PURPOSE The purpose of this article is to review current evidence available for alpha-lipoic acid (ALA) and its ability to improve symptoms of peripheral diabetic neuropathy (PDN). METHODS This article searched MEDLINE from 1966 to November 2005 to identify clinical trials that supplemented ALA to individuals with type 1 or type 2 diabetes and positive sensory symptoms of PDN. Clinical trials to be included in this review met specific criteria of randomization, double masking, and placebo-controlled design. RESULTS The search results produced 5 clinical trials that met the prerequisites for this review. ALA appears to improve neuropathic symptoms and deficits when administered via parenteral supplementation over a 3-week period. Oral treatment with ALA appears to have more conflicting data whether it improves sensory symptoms or just neuropathic deficits alone. An oral regimen of ALA and optimal length of treatment remains unclear. Both parenteral and up to a 2-year time period of oral supplementation of ALA appears to be safe without affecting glycemic control. CONCLUSIONS Based on these results, ALA should be considered as a treatment option for patients with PDN. When discussing supplementation with patients, it is important to discuss potential side effects; vitamin, mineral, and drug interactions; and current evidence available regarding efficacy.

Abstract
BACKGROUND Aging adversely affects balance and increases the propensity to slip and fall. Loss of plantar sensation due to diabetic peripheral neuropathy and other diseases has been shown to further increase this propensity to fall. The ancient Chinese art of Tai Chi has been previously shown as a method to improve balance in healthy elderly adults. METHODS The aim of this study was to determine if Tai Chi intervention improved both balance and plantar sensory perception in healthy elderly adults and elderly adults with diabetes and plantar sensory loss. Elderly subjects (mean +/- SD age = 73.1 +/- 5.9 years, n = 18) were tested for plantar sensory ability and several balance metrics before Tai Chi training and again after 6 months of weekly sessions. Participants were grouped by initial sensory perception scores (as measured by a vibrometer) in order to make inferences on the effects of Tai Chi on sensory perception. RESULTS Plantar sensation results show all participants showed significant improvement in sensory ability with the 6 months of Tai Chi training. All groups also had a general improvement in all balance measures, with the greatest improvement seen in those subjects with large sensory losses. Hemoglobin A1C measurements also decreased as a result of the intervention. CONCLUSION This study demonstrates the effectiveness of Tai Chi training as a method of improving plantar sensation and balance in elderly adults and elderly adults with diabetes with a large plantar sensation loss.

Abstract
Sensorineural hearing loss is more common in patients with diabetes than in the control nondiabetic patients, and severity of hearing loss seemed to correlate with progression of disease. This may be due to microangiopathic disease in the inner ear. References for diabetic microangiopathy are presented. Sensorineural hearing loss can often be helped by hearing aids. During the last decade there have been significant developments in hearing aid technology. Progress began with the presentation of programmable hearing aids in the late 1980's. The first hearing aids with fully digital signal processing became commercially available in 1995. The hearing aid is programmable, which means that it can be adjusted individually by a hearing healthcare professional (hearing aid fitting at departments of phoniatrics and of audiology in our country). The article gives an outline of indications for hearing aids.

Abstract
Two attitudes can be proposed, one consisting of making a diagnosis of neuropathy, the other seeking to grade the stage that it has reached in order to give a prognosis and above all determine the right way in which to educate the patient. In order to do this, it is important for the diagnosis to be thorough. It should be based both on listening to what the patient has to say and examining him/her. It is vital to listen to the patient because the warning signs are discreet, yet very evocative, and they will be a great help in making a positive diagnosis. They should not be confused with signs of arterial damage. They should then be interpreted by means of clinical examination and the tools that are available, i.e. essentially monitoring the osteo-tendinous reflexes and sensory signs. The sensory signs can only be studied with high-quality instruments, i.e. either a monofilament of proven technical quality and that should be used with care in line with good clinical practice recommendations, or by using a graduated tuning fork, or a neuroesthesiometer which will make it possible to obtained graduated responses, not simply binary responses of the "yes/no" variety. A whole series of scores have been put forward combining both functional and physical signs, making it possible to try to quantify the stage reached and the extent of the neuropathy. It is only by using a thorough and regularly applied routine that we can progress to establishing a better prognosis and providing a better educational service for the patient.

Abstract
The most common complaint of neuropathic patients is that they were unaware of the neuropathic pathway until it caused a complication. Foot treatment, protection, and amputation prevention historically have been overlooked or covered only slightly in medical education. Chronic neuropathic complications have been seen to have an unavoidable outcome. In many areas, there are no certified orthotists or local health care practitioners who are trained in off-loading techniques. The goal of treatment of a neuropathic or dysvascular patient is to preserve the limb and ambulatory function. Techniques can be shared between disciplines for improved outcomes for neuropathic patients. The combined team expertise with state-of-the-art techniques have enabled wound healing, limb salvage, and improved quality of life for this high-risk population.

Abstract
This paper presents details of the study undertaken to find the effects of foot sole hardness, thickness and footwear on walking-foot pressure distribution parameters (power ratio (PR)) in diabetic neuropathy. The foot sole hardness is characterized by Shore level. PR represents the ratio of high-frequency power to the total power in the power spectrum of the walking-foot pressure image distribution obtained from the optical pedobarograph. Spatial frequency distributions in the walking-foot pressure images were analysed to calculate the PR in each of the foot sole areas at different levels of foot sole sensation loss and mechanical and geometrical properties. The results show that the increase in PR in the upper foot sole Shore ranges (30-40) is 1.2-2.5 times the corresponding increase in lower Shore ranges (20-30) for some foot sole areas, implying a higher possibility of development of plantar ulcers when combined with deterioration of foot sole sensation. Plantar ulcers are found in feet with foot sole Shore values of 30, a sensation level of 45 mN and PR of 35; for Shore values of 40, sensation levels of 100 mN, with PR 52; and for Shore values above 40, sensation level > 100 mN with PR 58. Providing microcellular rubber insole footwear based on optimum hardness and thickness was found to be helpful in healing plantar ulcers in three to four weeks. Wearing preventive footwear for six months reduced hardness of the foot sole and PR values to near-normal values.

Abstract
Medical footwear provides solutions for structural or functional foot problems. Individuals with normal feet do not require medical footwear. In diabetic patients with neuropathy and foot deformity, the use of medical footwear protects the foot, reduces the plantar pressures and significantly reduces the rate of ulcers formation and amputations. Shoes have different designs, heights, and may be constructed of differing materials depending upon the nature of the needed corrections. Structurally, shoes can be viewed as consisting of a sole and an upper portion. Both these entities can be further sub-divided into components and shapes, each one providing a different corrective feature. Ordering medical footwear requires the same specificity as with the provision of medications. In Israel, shoes are provided by the Ministry of Health to patients according to specific criteria. The provision and quality control is conducted through a selected panel of doctors, chosen by the Lewis National Institute of Rehabilitation, and working in public hospitals.

Abstract
AIMS/HYPOTHESIS The effect of a foot ulcer on health-related quality of life (HRQoL) of patients with diabetes mellitus and their caregivers is unclear, and was therefore evaluated prospectively in this multicentre study. METHODS HRQoL according to the 36-item health-related quality of life questionnaire (SF-36) of 294 patients (ulcer duration > or = 4 weeks) and 153 caregivers was analysed at baseline (time-point zero [T0]), once the ulcer was healed or after 20 weeks (time-point 1 [T1]), and 3 months later (time-point 2 [T2]). Patients with severe ischaemia were excluded. RESULTS The mean age of the patients was 60 years, 72% were male, and time since diagnosis of diabetes was 17 years. Patients reported a low HRQoL on all SF-36 subscales. At T1, HRQoL scores in physical and social functioning were higher in patients with a healed vs a non-healed ulcer (p<0.05). At T2, these differences were larger, with higher scores for physical and social functioning, role physical and the physical summary score (all p<0.05). Within-group analysis revealed that HRQoL improved in different subscales in patients with a healed ulcer and worsened in patients with a persistent ulcer from T0 to T2 (all p<0.05). The caregivers of patients with a persisting ulcer had more emotional difficulties at T2. CONCLUSIONS/INTERPRETATION Diabetic patients with a healed foot ulcer had a higher HRQoL than patients with a persisting ulcer. Healing of a foot ulcer resulted in a marked improvement of several SF-36 subscales 3 months after healing (from T0 to T2). HRQoL declined progressively when the ulcer did not heal. A diabetic foot ulcer appeared to be a large emotional burden on the patients' caregivers, as well.

Abstract
CONTEXT AND OBJECTIVE Physiotherapy can contribute towards recovering or preventing physical and sensory alterations in diabetic neuropathy patients. Our objective was to create and apply a protocol for functional assessment of diabetic neuropathy patients' lower limbs, to guide future physiotherapy. DESIGN AND SETTING Clinical study at the University Hospital and teaching/research center of Universidade de São Paulo. METHODS An intentional sample of diabetic neuropathy patients was utilized. The protocol was divided into: (1) preliminary investigation with identification of relevant clinical diabetes and neuropathy characteristics; (2) thermal, tactile and proprioceptive sensitivity tests on the feet; (3) evaluations of muscle function, range of motion, lower limb function, foot anthropometry. RESULTS The patients' mean age was 57 years, and they had had the diagnosis for 13 years on average. Distal numbness and tingling/prickling were present in 62% and 67%, respectively. There were tactile sensitivity alterations above the heel in 50%, with thermal sensitivity in 40% to 60%. The worst muscle function test responses were at the triceps surae and foot intrinsic muscles. Longitudinal plantar arches were lowered in 50%. Decreased thermal and tactile sensitivity of the heels was found. There was a general reduction in range of motion. CONCLUSIONS The results provided detailed characterization of the patients. This protocol may be easily applied in healthcare services, since it requires little equipment, at low cost, and it is well understood by patients.

Abstract
AIMS Electrical spinal cord stimulation (ESCS) is a technique for the management of chronic painful diabetic neuropathy (CPDN) affecting the lower limbs. We assessed the efficacy and complication rate of ESCS implanted at least 7 years previously in eight patients. METHODS After a trial period of percutaneous stimulation, eight male patients had been implanted with a permanent system. Mean age at implantation was 53.5 years and all patients were insulin treated with stage 3 severe disabling CPDN of at least 1 year's duration. The ESCS was removed from one patient at 4 months because of system failure and one patient died 2 months after implantation from a myocardial infarction. RESULTS Six patients were reviewed a mean of 3.3 years post-implantation. With the stimulator off, McGill pain questionnaire (MPQ) scores (a measure of the quality and severity of pain) were similar to MPQ scores prior to ESCS insertion. Pain scores (visual analogue scale) were measured with the stimulator off and on, respectively: background pain [74.5 (63-79) mm vs. 25 (17-33) mm, median (interquartile range), P = 0.03), peak pain (85 (80-92) mm vs. 19 (11-47) mm, P = 0.03]. There were two further cardiovascular deaths (these patients had continued pain relief) and the four surviving patients were reassessed at 7.5 (range 7-8.5) years: background pain [73 (65-77) mm vs. 33 (28-36) mm, median (interquartile range)], peak pain [86 (81-94) mm vs. 42 (31-53) mm]. Late complications (> 6 months post-insertion) occurred in two patients; electrode damage secondary to trauma requiring replacement (n = 1), and skin peeling under the transmitter site (n = 1). One patient had a second electrode implanted in the cervical region which relieved typical neuropathic hand pains. CONCLUSIONS ESCS can continue to provide significant pain relief over a prolonged period of time with little associated morbidity.

Abstract
AIMS Peripheral neuropathy affects more than a third of diabetic patients, of whom a significant minority will have disabling symptoms. The aim of this study was to assess the efficacy of pulsed-dose electrical stimulation (through stocking electrodes) in the treatment of painful diabetic neuropathy. METHODS Thirty patients with painful diabetic neuropathy were consecutively randomised to wear silver-plated nylon-dacron stocking electrodes for 8 h a night for 6 weeks (pulsed electric current of 50 micro amps delivered by a microcomputer). The control, identical stockings received an insignificant current (5 micro amps). Pre-treatment, weekly and end-of-treatment pain and sleep disturbance scores were recorded. RESULTS Fourteen patients completed the study (the 16 non-completers withdrew during the first phase). Mean (+/- sd) age: 57.5 +/- 10.5 years; HbA(1c): 8.3 +/- 1.4%; median (IQR) duration of diabetes: 14.5 (7.6-19.3) years; duration of neuropathy: 4 (3-7) years. Active treatment and control produced similar reductions in pain scores [median (IQR): 40.1 (4.7-97.7)% vs. 49.2 (0.2-91.1)%, P = 0.70] and sleep disturbance scores [median (IQR): 31.1 (-4.6 to 85.4)% vs. 42.6 (-16.2 to 91.1)%, P = 0.70]. Non-completers (seven on active treatment, nine on control) withdrew for similar reasons (inconvenience, exacerbation of symptoms, dermatitis). CONCLUSIONS There is no evidence from these results that this treatment is more effective than control in the treatment of painful diabetic neuropathy.

OBJECTIVE To study the effects of custom-made insoles on plantar pressures and load redistribution in neuropathic diabetic patients with foot deformity. DESIGN Cross-sectional. BACKGROUND Although custom-made insoles are commonly prescribed to diabetic patients, little quantitative data on their mechanical action exists. METHODS Regional in-shoe peak pressures and force-time integrals were measured during walking in the feet of 20 neuropathic diabetic subjects with foot deformity who wore flat or custom-made insoles. Twenty-one feet with elevated risk for ulceration at the first metatarsal head were analysed. Load redistribution resulting from custom-made insoles was assessed using a new load-transfer algorithm. RESULTS Custom-made insoles significantly reduced peak pressures and force-time integrals in the heel and first metatarsal head regions; pressures and integrals were significantly increased in the medial midfoot region compared with flat insoles. Custom-made insoles successfully reduced pressures in and integrals at the first metatarsal head in 7/21 feet, were moderately successful in another seven, but failed in the remaining seven. Load transfer was greatest from the lateral heel to the medial midfoot regions. CONCLUSIONS Custom-made insoles were more effective than flat insoles in off-loading the first metatarsal head region, but with considerable variability between individuals. Most off-loading occurred in the heel (not a region typically at risk). The load transfer algorithm effectively analyses custom-made-insole action. RELEVANCE Because similar insole modifications apparently exert different effects in different patients, a comprehensive evaluation of custom designs using in-shoe pressure measurement should ideally be conducted before dispensing insoles to diabetic patients with neuropathy and foot deformity.

Abstract
Pedographic systems are now in use in many research centers and hospitals throughout the world. The platform system permits rapid and accurate static and dynamic measurement of the local pressure loading on the plantar surface of the foot, and also permits a functional assessment of the roll-over process in the bare foot. The in-shoe system employing an insole measures the pressure distribution within an orthopedic shoe and enables an accurate comparison of the loading situation before and after fitting. As an additional diagnostic tool, pedography improves preventive measures and the quality of the orthopedic treatment of the diabetic foot.

Abstract
OBJECTIVE To examine the effect of different types of rocker soles on plantar pressures. DESIGN In-shoe plantar pressures were measured in subjects without deformity with baseline shoes and 3 types of rockers: toe-only, negative heel, and double. SETTING Medical college. PARTICIPANTS Forty healthy patients (20 men, 20 women) without foot deformity. INTERVENTIONS Plantar pressures were recorded over a 2 1/2-hour test period with over 400 steps analyzed for each type of rocker sole. Peak pressures, pressure-time integral (PTI), and sensor contact duration were computed for each step. MAIN OUTCOME MEASURES Peak plantar pressure PTI, and contact duration were compared for each rocker with a baseline shoe. RESULTS Significant reduction (P<.01) in peak pressure and PTI were recorded across the forefoot for all 3 rockers. The reduction of pressure at the forefoot was balanced by shifting pressure to the midfoot with the negative heel and toe-only rockers. CONCLUSION This study lends scientific credence to the prescription of rocker soles for patients who need forefoot pressure reduction, such as in diabetic neuropathy and possible ulceration.

Abstract
Painful diabetic neuropathy is just one of a myriad of secondary conditions that may result from poor glycaemic control. Educating the patient to suspect diabetic complications, understanding why they may occur, what their progression is likely to be and what measures can be taken to avoid them can significantly improve outcomes. Education within the diabetes management framework needs to be consistent, prioritised, tailored to the needs of each patient and ongoing in order to be maximally effective, with tight glycaemic control playing the anchoring central role. The specialist diabetes nurse is in the ideal situation to coordinate this education and to ensure that the patient with diabetes receives the care and support needed to take dual responsibility for their condition.

Abstract
OBJECTIVE To determine if a difference exists in the plantar soft tissue of patients with diabetes mellitus (DM) and peripheral neuropathy (PN) compared with age-matched controls. DESIGN Case-control study with a parallel 3-element 1-dimensional viscoelastic model developed to characterize indentation data. SETTING Data collection performed in an academic physical therapy laboratory. PARTICIPANTS Forty subjects were recruited into 2 groups (20 subjects with DM, PN, and history of plantar ulcers; 20 control subjects), matched for age (DM: 55.22+/-9.39 y; control: 55.91+/-10.97 y), gender (DM: 14 men, 6 women; control: 14 men, 6 women), and body mass index (DM: 32.96+/-8.39 kg/m(2); control: 32.58+/-7.69 kg/m(2)). INTERVENTIONS The plantar soft tissue stiffness was measured over the first, third, and fifth metatarsals, and heel of each subject using an indentor system that accurately measures force/displacement (F/D) data. A parallel 3-element viscoelastic mechanical model was then used to transform the F/D data into values that were used to make stiffness assessments. MAIN OUTCOME MEASURE The element coefficients of our model indicated the stiffness of the plantar tissue. RESULTS The plantar tissue of the subjects with DM over the metatarsal heads was stiffer than the control population as indicated by one of the spring constants in the parallel 3-element model (first: 1.13+/-0.55 N/mm vs.72+/-.32 N/mm; third:.96+/-.32 N/mm vs.79+/-.17 N/mm; fifth:.90+/-.31 N/mm vs.69+/-.28 N/mm; P<.05). CONCLUSIONS The plantar tissue of subjects with DM, PN, and a history of ulcers was stiffer than control subjects. However, additional research is needed to determine the relationship among increased soft tissue stiffness, plantar pressures, and skin breakdown.

Abstract
Up to now no obligatory guidelines for the assessment of working capability exist for patients with diabetes and peripheral and/or autonomic neuropathy. Precise investigations of clinical symptoms of an existing polyneuropathy are preconditions for this assessment. For the evaluation of the working capability a detailed analysis of working conditions and working place is necessary. Special attention is needed with respect to the prophylaxis of the diabetic foot. Cardiac autonomic neuropathy as well as the autonomic neuropathy of the gastro-intestinal tract are of importance for the assessment of working capability. In practice inadequate diagnostic procedures occur up to now and assessment of working capability is mostly not included into these diagnostic procedures. The processing of corresponding recommendations should be a common task of diabetologists and job physicians.

Abstract
OBJECTIVE To test the hypothesis that vibrotactile detection thresholds in older adults, patients with stroke, and patients with diabetic neuropathy can be significantly reduced with the introduction of mechanical noise. DESIGN A randomized controlled study. SETTING A university research laboratory. PARTICIPANTS Twelve healthy elderly subjects (age range, 67-85y), 5 patients with stroke (age range, 24-64y), and 8 patients with diabetic neuropathy (age range, 53-77y). INTERVENTIONS Each subject's detection thresholds (ie, minimum level of stimulus to be detected) for a vibrotactile stimulus without and with mechanical noise (ie, random vibration with a small intensity) were determined by using a 4-, 2-, and 1-stepping algorithm. The stimuli were applied to the fingertip and/or to the first metatarsal of the foot. MAIN OUTCOME MEASURE Detection threshold for a vibrotactile stimulus. RESULTS The detection threshold at the fingertip for the vibration stimulus with mechanical noise was significantly lower than that without mechanical noise for all 12 elderly subjects, for 4 of the 5 patients with stroke, and all 8 patients with diabetic neuropathy. For the 8 patients with diabetes, mechanical noise also significantly reduced the vibrotactile detection threshold at the foot. CONCLUSIONS Reduced vibrotactile sensitivity in older adults, patients with stroke, and patients with diabetic neuropathy can be significantly improved with input mechanical noise. Noise-based techniques and devices may prove useful in overcoming age- and disease-related losses in sensorimotor function.

Comparison of cycling kinetics during recumbent bicycling in subjects with and without diabetes. JOURNAL OF REHABILITATION RESEARCH AND DEVELOPMENT 2002; 39:13-20.

Abstract
We compared recumbent bicycle kinetics in diabetic peripheral neuropathy and nondiabetic men (nine per group). 3D kinematic and force pedal data in a linked-segment model were used. The generalized muscle moment (GMM) patterns were similar between the two groups except for (1) decreased maximum knee flexor moment, (2) increased minimum knee flexor GMM, and (3) maximum hip extensor GMM by the diabetic subjects. Similar to the walking support moment, a summation moment immutable pattern was observed, although the groups accomplished it differently. The diabetic group utilized the hip during the power phase and the knee during the recovery phase. The nondiabetic group utilized both joints together during both phases. Differences in ankle GMM were not observed, suggesting further research using the recumbent bicycle as an exercise modality for diabetic peripheral neuropathy patients to enhance ankle range of motion and strength, commonly observed walking deficits.

Abstract
A prospective study of 29 patients with diabetic neuropathy and 47 nondiabetic patients with tarsal tunnel syndrome were evaluated with computer-assisted neurosensory testing at three sites on the foot. The sensitivity and specificity of one-point static touch thresholds for identifying the presence of large fiber axonal loss was done using the calculated thresholds for monofilaments derived from their markings. The sensitivity for one-point static touch in identifying axonal loss was 33% for the 5.07, 38% for the 4.93, 50% for the 4.17, and 60% for the 4.08 monofilament-equivalent, with a specificity of 100% at each level. Therefore, one-point static touch testing, even using monofilaments thinner than 5.07, has a high percentage of false-negative results in identifying patients with axonal loss.
