Multifactorial inspiratory muscle training and its impact on respiratory and functional parameters of patients with diabetic polyneuropathy-A Randomized Controlled Trial.

BACKGROUND AND PURPOSE: Diabetic polyneuropathy is a long-standing microvascular complication of diabetes that affects the postural control and functional mobility of patients. There are other microvascular complications, including pulmonary complications that reduce lung function. Multifactorial Inspiratory Muscle Training (IMT) can act as a home-based technique targeted to affect both these complications. This study aims to determine the effects of IMT on respiratory and functional parameters in diabetic polyneuropathy patients. METHODS: This is a Pre-Test Post-Test Randomized Controlled Trial (NCT#04947163) with 62 diabetic polyneuropathy patients. Each was randomly assigned to the IMT or sham-IMT group. Both the groups performed OTAGO exercises , with the sham-IMT group performing IMT at 15% of baseline maximal inspiratory pressure (MIP), whereas IMT were trained at 50% of baseline MIP as an initial intensity, which was increased as per the tolerance of patients. Both groups performed training for 12 weeks. The study investigated diaphragmatic strength, pulmonary function, functional capacity through 6MWT, 30s sit to stand test and anterior trunk muscle endurance tested through sit up test as outcome variables. Data was analysed on SPSS v26 at the significance level of 0.0.5. RESULTS: The IMT group significantly improved diaphragmatic strength, pulmonary function, 6MWT and anterior trunk muscle endurance when compared to the sham-IMT group. CONCLUSION: The study concluded that home-based IMT can improve pulmonary parameters including diaphragmatic strength and lung function as well as functional parameters including functional capacity in patients with diabetic polyneuropathy. The study was registered at ClinicalTrials.gov, NCT#04947163.

A novel proprioceptive rehabilitation program: A pilot randomized controlled trail as an approach to address proprioceptive deficits in patients with diabetic polyneuropathy.

BACKGROUND: Diabetic polyneuropathy (DPN) is a notable microvascular complication of DM, affecting 16%-66% globally. DPN often leads to proprioceptive deficits in the lower limbs (LL), leading to impaired functional performance. However, evidence supporting proprioceptive rehabilitation programs (PRP) for DPN remains scarce. AIMS: This pilot study aims to evaluate the effectiveness of a novel 12-week PRP on LL static and dynamic proprioception and shed light on the potential benefits of PRP for DPN population. METHODS: Randomized Controlled Trail was conducted among 30 DPN patients (age 53.25±7.72 years, BMI 24.01±1.41 and DM duration 9.48±6.45 years), randomly allocated to intervention (n = 15) or control (n = 15) groups. The intervention group received PRP 3 times/week for 12 weeks. The control group received no exercise. Both groups received regular diabetic care. Static and dynamic proprioception of both LL were assessed at baseline, 6 weeks and 12 weeks. Position-reposition test was used to assess ankle joint position sense by obtaining difference between target and reproduced angles. Error in detecting knee angle and speed were obtained by performing Lower Limb Matching and Sense of Movement tests respectively to assess dynamic proprioception. RESULTS: Two-way ANOVA and paired comparisons revealed, no significant improvement in proprioceptive deficits at 6 weeks (p>0.05), but significant improvement was achieved at 12-weeks (p<0.05) in the intervention group. Mean errors in Pposition re-position(R:p<0.001, L;p<0.001) and Lower limb matching (R:p<0.001, L;p<0.001) tests reduced by 5° and 10° respectively, indicating a70% improvement in the intervention group. Error of detecting speed reduced only on right side by 0.041ms-1 accounting for a 42% improvement. No improvements were observed in the control group. CONCLUSIONS: Novel 12-week PRP may yield a significant reduction in LL proprioceptive deficits among DPN patients. Future RCTs with larger samples should compare the effectiveness of this PRP compared with conventional rehabilitation programs.

Novel Vibrating Foot Orthoses for Improving Tactile Sensation in Type 2 Diabetes With Peripheral Neuropathy.

Improving tactile sensation by vibrating insoles was recommended to prevent foot ulcers in diabetic peripheral neuropathy (DPN). Lack of an insole design for diabetics was a challenge. Clinical trials on applying vibrating insoles with noise and stochastic resonance (SR) stimulating tactile were also required. In this study, vibrating foot orthoses (VFO) with a total contact design based on orthotics were proposed to provide proper insoles for diabetes. This study aimed to determine if VFO were beneficial at enhancing tactile in DPN. VFO were developed in combination with individual's custom-made foot orthoses and stimulation signals-integrating random 0-100 Hz square wave pulse signals with pseudorandom white noise by a SR approach. Sixty patients with mild-to-severe DPN were randomized to conduct crossover experiments: using and without VFO for 60 minutes stimulation at 90% of individuals' vibration perception threshold (VPT) level. VPT values when using VFO at the 1st and 5th metatarsophalangeal joints of the left foot decreased by 9.35% ( [Formula: see text].001); 9.04% ( [Formula: see text].001), and of the right foot decreased by 7.63% ( [Formula: see text].001); 7.24% ( [Formula: see text].001), respectively. Without VFO, there was no significant difference. Subgroups of mild and moderate DPN tended to benefit greatly from utilizing VFO. VFO can improve tactile in DPN. VFO may contribute to restoring/prolonging tactile and protective sensations, also decreasing peripheral nervous system deterioration. VFO might be useful for neurorehabilitation, and help prevent foot ulcers and disabilities.

A Systematic Review of the Effect of Physical Rehabilitation on Balance in People with Diabetic Peripheral Neuropathy Who are at Risk of Falling.

Background: Falls are a significant issue in people with diabetic peripheral neuropathy. Balance interventions have been broadly administered in individuals with diabetic peripheral neuropathy, but the effects on static and dynamic balance in those who are at risk of falling have not yet been comprehensively reviewed. Objective: To provide a synthesis of the literature regarding the effectiveness of physical rehabilitation interventions to improve balance in people with diabetic peripheral neuropathy who are at risk of falling. Methods: Four databases (PubMed, Embase, the Cochrane Central Register of Controlled Trials, Cumulated Index in Nursing and Allied Health Literature) were systematically searched from inception to July 2022. Articles meeting the eligibility criteria (ie, participants with diabetic peripheral neuropathy and at risk of falling based on validated fall balance outcome risk cut off scores; inclusion of physical rehabilitation intervention) underwent a quality assessment using the Physiotherapy Evidence Database scale. Data regarding fall risk was extracted. Results: Sixteen studies met the eligibility criteria. Participants in six studies improved balance such that their fall risk was reduced from a moderate-high risk of falls to no or low risk of falls from pre- to post-intervention. Interventions within these six studies were variable and included balance exercise, gait training, endurance, tai-chi with mental imagery, proprioceptive training, aerobic training, and yoga. Participants in seven of the remaining studies showed no improvement and participants in three studies showed mixed results regarding improved balance and reduced fall risk status by post-intervention. Conclusion: While physical rehabilitation is sufficient to improve balance in individuals with diabetic peripheral neuropathy who are at risk of falling, few interventions led to improved balance and reduced fall risk. Interventions involving intentional weight shifting, manipulation of the base of support, and displacement of the center of mass such as tai-chi and yoga appear to provide the most consistent results in terms of decreasing fall risk. To better understand the effectiveness of rehabilitation on balance and fall risk, future studies should examine the impact of physical interventions on prospective fall rates.

Combined effects of strength and balance training versus aerobic training on balance, neuropathy symptoms and quality of life in patients with diabetic peripheral neuropathy.

BACKGROUND: Diabetic peripheral neuropathy (DPN) occurs in >50% of diabetic patients and is a high risk-factor of balance problems and risk of falls. Impaired balance can lead to reduced function, which has a detrimental effect on patients' quality of life. Structured strength and balance training can result in sustained improvements in muscle strength, coordination, balance, functional status and quality of life. OBJECTIVE: To determine the combined effects of strength and balance training versus aerobic training on balance, severity of symptoms of DPN, and quality of life in patients with DPN. METHODS: This double blinded, two arm parallel design Randomized Clinical Trial. The study was conducted from March to December 2020 in the AIMS diabetic center Peshawar, Pakistan. Participants were selected through convenience sampling technique and randomly allocated into strength plus balance and aerobic training groups. Type 2 diabetic patients of both sexes, aged 40 to 80 years, with a Toronto neuropathy score ≥6 recruited, while patients with ulceration/infection of feet, medical/Surgical conditions, and non-ambulatory patients were excluded from this study. Intervention was applied 3 days a week for 8 weeks. The Toronto clinical neuropathy system was used to assess neuropathy severity, SF-36 to assess quality of life and the Berg balance scale was used for assessment of balance. Assessment was done at the baseline and after 8 weeks of intervention using SPSS. Version 22 was used for analysis. RESULTS: The mean age of the participants was 60.80 ± 9.73. Between group analysis, which showed were statistically insignificant for neuropathy severity, balance and all domains of quality of life (p-value >0.05) except SF-36 General Health Perception Score, with Mean ± SD of 62.50 ± 7.54 in group A versus Mean ± SD of in group B 60.00 ± 15.98 (p-value = 0.05). Within group analysis showed statistically significant results for neuropathy severity, balance and all domains of quality of life (p-value<0.05). CONCLUSION: This study concluded that there is a statistically significant effect of structured balance and strength training and aerobic training on severity of DPN, balance and quality of life. But there was no statistically significant difference in improvement between the two intervention groups.

The effects of vibrating shoe insoles on standing balance, walking, and ankle-foot muscle activity in adults with diabetic peripheral neuropathy.

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.

Sensorimotor Training Improves Gait, Ankle Joint Proprioception, and Quality of Life in Patients With Diabetic Peripheral Neuropathy: A Single-Blinded Randomized Controlled Trial.

OBJECTIVE: To investigate the effect of sensorimotor training on gait, ankle joint proprioception, and quality of life in diabetic peripheral neuropathy patients. DESIGN: A prospective, single-blind, randomized controlled experiment was performed. Forty patients with diabetic peripheral neuropathy aged 50-65 yrs were distributed randomly into two groups, the sensorimotor training group ( n = 20), and the control group ( n = 20). Both groups attended awareness sessions about diabetes and foot care for 30 mins, every 2 wks. Moreover, the sensorimotor training group received 6 wks (3 d/wk) of sensorimotor training. Spatiotemporal gait parameters, proprioception accuracy of the ankle joint, and quality of life were measured before and after 6 wks of intervention. RESULTS: Regarding baseline data, no significant differences were identified among groups ( P > 0.05). After 6-wk intervention, the sensorimotor training group exhibited significant improvements in all outcome variables ( P < 0.001), while the control group showed significant changes in quality of life only ( P = 0.03). Comparing groups after intervention reveals statistically significant differences in all measured variables in favor of the sensorimotor training group ( P < 0.001). CONCLUSIONS: Sensorimotor training may improve spatiotemporal gait parameters, ankle joint proprioception, and quality of life of patients with diabetic peripheral neuropathy.

Feasibility of a home-based foot-ankle exercise programme for musculoskeletal dysfunctions in people with diabetes: randomised controlled FOotCAre (FOCA) Trial II.

This study sought to assess the feasibility of design, adherence, satisfaction, safety and changes in outcomes followed by a home-based foot-ankle exercise guided by a booklet in individuals with diabetic peripheral neuropathy (DPN). 20 participants were allocated usual care [control group (CG)] or usual care plus home-based foot-ankle exercises [intervention group (IG)] for 8 weeks. For feasibility, we assessed contact, preliminary screening and recruitment rates, adherence, and using a 5-point Likert scale to satisfaction and safety of the booklet. In the IG, we assessed preliminary changes in DPN symptoms, DPN severity (classified by a fuzzy model) and foot-ankle range of motion between baseline and Week 8. In the first 20 weeks, 1310 individuals were screened for eligibility by phone contact. Contact rate was 89% (contacted participants/20w), preliminary screening success 28% (participants underwent screening/20w), and recruitment rate 1.0 participants/week (eligible participants/20w). The recruitment rate was less than the ideal rate of 5 participants/week. The adherence to the exercises programme was 77%, and the dropout was 11% and 9% for the IG and CG, respectively. In the IG, participants' median level of satisfaction was 4 (IQR: 4-5) and perceived safety was 3 (IQR: 3-5). IG significantly decreased the DPN severity (p = 0.020), increased hallux relative to forefoot (first metatarsal) range of motion (ROM) (p < 0.001) and decreased maximum forefoot relative to hindfoot (midfoot motion) dorsiflexion during gait (p = 0.029). The home-based programme was feasible, satisfactory, safe and showed preliminary positive changes in DPN severity and foot motion during gait.Trial Registration ClinicalTrials.gov, NCT04008745.

Sensorimotor and gait training improves proprioception, nerve function, and muscular activation in patients with diabetic peripheral neuropathy: a randomized control trial.

OBJECTIVES: To examine the effect of sensorimotor and gait training on proprioception, nerve function, and muscle activation in diabetic peripheral neuropathy (DPN) patients. METHODS: Thirty-eight (25 male and 13 female) participants with DPN were selected and randomly allocated to intervention and control group. Participants in the intervention group were provided sensorimotor and gait training for eight weeks (3 days/week) along with diabetes and foot care education; participants in the control group received diabetes and foot care education only. Outcome measures involved proprioception, nerve conduction studies of peroneal and tibial nerve, and activation of lower limb muscles and multifidus while standing with eyes open and eyes closed, and treadmill walking. RESULTS: Mixed ANOVA revealed significant time effect and time×group interaction of proprioception in all four directions (p<0.05). The conduction velocity of peroneal nerve revealed significant time effect (p=0.007) and time×group interaction (p=0.022). Interaction effect was found to be significant for medial gastrocnemius and multifidus while standing with eyes open as well as with eyes closed (p≤0.004). Only multifidus showed significant group (p=0.002) and interaction effect (p=0.003) during walking. CONCLUSIONS: Sensorimotor and gait training is an effective tool for improvement of proprioception and nerve function. It benefits muscle activation around ankle and multifidus during postural control and walking in DPN patients.

Effect of an educational booklet for prevention and treatment of foot musculoskeletal dysfunctions in people with diabetic neuropathy: the FOotCAre (FOCA) trial II, a study protocol of a randomized controlled trial.

BACKGROUND: This study is a part of a series of two clinical trials. We consider diabetic polyneuropathy (DPN), a common chronic and progressive complication of diabetes mellitus that has several impacts on individuals' foot health and quality of life. Based on the current trends of self-monitoring and self-care, providing a tool with foot-related exercises and educational care may help patients to avoid or reduce the musculoskeletal complications resulting from DPN, improving autonomous performance in daily living tasks. The aim of this trial is to evaluate the effects of an educational booklet for foot care and foot muscle strengthening on DPN symptoms and severity, clinical outcomes, and gait biomechanics in patients with DPN. METHODS/DESIGN: The FOotCAre (FOCA) trial II study has been designed as a single-blind, two-parallel-arm randomized controlled trial. It will include 48 patients with DPN who will be randomly allocated to a control (recommended foot care by international consensus with no foot exercises) group or an intervention (foot-related exercises using an educational booklet three times/week at home for 8 weeks) group. Participants from both groups will be assessed at baseline, after 8 weeks, and at 16 weeks for follow-up. The primary outcomes are the DPN symptoms and severity, and the secondary outcomes are foot-ankle kinematics, gait kinetics, plantar pressure distribution during gait, tactile and vibratory sensitivities, foot strength, functional balance, and foot health and functionality. DISCUSSION: The booklet is a management tool that allows users to be autonomous in their treatment by choosing how and where to perform the exercises. This allows the patients to perform the exercises regularly as a continuous habit for foot care and health, which is an important element in the management of the diabetic foot. As the booklet focuses on specific foot-ankle exercises, we expect that it will improve the clinical aspects of DPN and produce beneficial biomechanical changes during gait, becoming a powerful self-management tool that can be easily implemented to improve the performance of daily living tasks. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04008745. Registered on 2 July 2019.

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.

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.

Effect of diverse physical rehabilitative interventions on static postural control in diabetic peripheral neuropathy: a systematic review.

BACKGROUND AND PURPOSE: There are diverse forms of rehabilitative techniques available to improve postural control in diabetic peripheral neuropathy but little is known about the efficacy of these techniques. The primary focus of this review is to find out the effectiveness of diverse rehabilitative interventions in improving postural control in type 2 induced diabetic peripheral neuropathy. Methods: Two reviewers independently scrutinized the included studies. The selected studies underwent quality assessment by PEDro scale. Randomized Controlled Trial (RCT) having a score of 4 or more were included in the review. A search was conducted in PUBMED, MEDLINE, CINAHL, EMBASE, PROQUEST, Science Direct, Cochrane Library, Physiotherapy Evidence Database (PEDro) and Google Scholar. The Medical Subject Headings (MeSH) related to the interventions were also taken into account. Results: A total of 563 studies were identified and finally 8 studies were included in the review process. The included studies were 3 in task-specific balance training, 1 in treadmill, 1 in strengthening, 2 in whole body vibration, and 1 study in pilates analyzing posture using static posturography. No RCTs were reportedly found under tai chi and yoga. Conclusions: Interventions related to task-specific approach in balance training, treadmill, strengthening, WBV showed improvement in static postural control. Intervention with pilates did not show any beneficial effects. However, there still remains a need for quality trials as the results of these studies were ambivalent in interpretation and quality of the studies were limited by small sample size and higher attrition rates.

An exercise program for people with severe peripheral neuropathy and diabetic foot ulcers - a case series on feasibility and safety.

Purpose: To examine a non-weightbearing exercise program for persons with severe peripheral neuropathy (PN) and a diabetic foot ulcer in terms of feasibility and safety.Materials and methods: Five men (mean (SD) age of 68.2 (7.1) years) with diabetes, severe peripheral neuropathy and an active foot ulcer, participated in a 10-week exercise program. Program adherence, patient satisfaction, healing of foot ulcers, adverse advents, ability to perform activities of daily life, and changes in muscle strength were assessed.Results: All participants completed the program with a session attendance from 85 to 95%, and with high satisfaction (≥9 points on a 10-point numeric rating scale). Only minor adverse events occurred, and ulcers were reduced for all participants, from a median of 1.9 (IQR, 1.1-7.3) cm2 to 0.0 (0.0-3.0) cm2. The distance on stationary bike was improved from a mean (SD) of 3.30 (1.1) to 5.36 (0.5) kilometers, and strength training loads were progressed. Ability to perform in self-selected activities of daily living improved from a median of 4.3 (2-5) to 6.7 (5-8) on the Patient Specific Functional Scale (0-10 points), while maximal isometric knee-extension muscle strength improved with 23%.Conclusions: A non-weightbearing exercise program for people with diabetes, severe peripheral neuropathy and foot ulcers seems feasible and safe. Further studies are needed to confirm these findings.Implications for rehabilitationAn exercise program designed for people with severe peripheral neuropathy and diabetic foot ulcers can be safe by means of not compromising healing of foot ulcers.Feasible in terms of attendance and progression.An alternative to passive waiting for ulcer to heal in a population already deconditioned.

Integrative studies to design and validate wearable footwear among neuropathic patients.

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.

Effects of a task-based biofeedback training program on improving sensorimotor function in neuropathic hands in diabetic patients: a randomized controlled trial.

BACKGROUND: Symptoms of diabetic hands have been gradually elucidated, however the interventions for these hand problems are typically underemphasized. Few studies have discussed intervention effects on sensorimotor problems in hands, which prevent diabetic patients from executing their daily routines and lower their quality of life (QoL). AIM: This study has investigated the effects of task-based biofeedback training compared with home-based programs on sensorimotor function and QoL in diabetic patients with neuropathic hands. DESIGN: A single blind randomized controlled trial. SETTING: Outpatient clinic at a university hospital. POPULATION: Thirty-eight patients with diabetic hand neuropathy whose sensorimotor functions were impaired based on screening with a pinch-holding-up activity (PHUA) test. METHODS: Participants were randomly assigned to either a computerized evaluation and re-education biofeedback (CERB) (N.=20) or a home-based (tendon gliding exercise in conjunction with resistive exercise) (N.=18) group. The primary outcome was sensorimotor control of a hand using the PHUA test. Secondary outcomes included changes in Semmes-Weinstein monofilament, two-point discrimination, the Purdue Pegboard test and a self-reported QoL questionnaire. The measurements were conducted before and after a 6-week treatment program. RESULTS: The CERB group significantly improved efficiency in pinch force output during the PHUA test by reducing the percentage of maximum pinch strength (change from 34.5±11.66 to 30.7±10.16%, P=0.001), and there was a statistically significant between-group difference (P=0.00, 95% CI: -12.59 to -3.34, F=9.42). The CERB group showed superior treatment effects as compared to the control group on the two-point discrimination results (P=0.01) as well as the pin insertion subtests in the Purdue pegboard test (P=0.01). The QoL results also revealed significant between-group differences in several items of the Diabetes-39 (P<0.05). CONCLUSIONS: This study showed that a task-based biofeedback training program provides superior benefits for restoration of hand sensorimotor functioning in diabetic patients as compared to a home-based program combining tendon gliding exercise and resistive exercise. CLINICAL REHABILITATION IMPACT: Using task-based biofeedback training as one of the rehabilitation strategies may be an effective approach for restoration of sensory function, precision pinch performance, hand dexterity, and QoL for patients with diabetes-related neuropathy.

The effect of exercise therapy combined with psychological therapy on physical activity and quality of life in patients with painful diabetic neuropathy: a systematic review.

Background and aims Approximately 25% of patients with diabetes mellitus type 2 (DMII) develop painful diabetic neuropathy (PDN). PDN is known to affect both mental and physical wellbeing, resulting in anxiety, depression, low quality of life and physical disability. Pharmacological treatment of PDN aims at pain relief and is often ineffective and/or has many side effects. Rehabilitation treatment modalities that are designed to help the patient deal with PDN related complaints, are mostly focussed on either physical (e.g. exercise therapy) or psychological aspects (e.g. cognitive behavioural therapy, CBT). There is emerging evidence that PDN can be approached from a biopsychosocial perspective, in which physical and psychosocial aspects are integrated. From this biopsychosocial approach it is plausible that integrated treatment modalities such as acceptance commitment therapy (ACT) or exposure in vivo (EXP) could be effective in patients with PDN. The objective of this review was to provide an overview of the current evidence on the effects of rehabilitation treatments that combine exercise therapies with psychological therapies in order to improve physical activity (PA) and quality of life (QoL) in patients with PDN. Methods Systematic review of the current literature. EMBASE, MEDLINE, Medline In-Process citations and e-Pubs ahead-of-print, Pedro, Web of Science, PsycINFO, CENTRAL, PubMed and Google Scholar were searched. All studies on interventions combining exercise therapy with psychological interventions in patients with PDN, aged >18 years, were included. Outcome measures were PA, QoL. Results The search resulted in 1603 records after removing duplicates. After screening on titles and abstracts, 100 records remained. From these, not one study reported on interventions that combined exercise therapy with psychological interventions. Through a secondary hand search, a total of three reviews were identified that described a total of five studies regarding either physical or psychological interventions in patients with PDN. These studies reported moderate effects of (1) mindfulness meditation on QoL, (2) CBT on pain severity, (3) mindfulness-based stress reduction intervention on function, health-related QoL, pain catastrophizing and depression, (4) aerobic exercise on QoL and (5) Tai Chi on glucose control, balance, neuropathic symptoms, and some dimensions of QoL in patients with PDN. All studies were of a moderate quality, and results should be interpreted with caution. Conclusions Based on increasing knowledge in the domain of chronic pain, it could be assumed that integrated rehabilitation treatments for patients with PDN are beneficial. There is no literature to support this and more research should be done on integrated biopsychosocial interventions in patients with PDN. Implications This empty review highlights the importance that more research should be done on integrated biopsychosocial interventions in patients with PDN. Currently, our research group is performing a study on the effects of EXP treatment in patients with PDN.

A Review of Beneficial Low-Intensity Exercises in Diabetic Peripheral Neuropathy Patients.

The American Diabetic Association standards of medical care for diabetic patients recommends moderate intensity exercise to help manage diabetes; however, this recommendation may be unmanageable for patients who have become inactive or unable to reach this intensity. The purpose of this review is to determine if low-intensity exercises demonstrate improvement in diabetic peripheral neuropathy symptoms in order to utilize these exercises as a starting point for inactive patients. Studies in low-intensity exercises from 2013 to May 2018 were systematically searched in PubMed, SCOPUS, and Cochrane Library databases. The studies in this research have shown that low-intensity resistance exercises have promising outcomes such as improvements in pain interference with daily activities, pain thresholds, and reductions in neuropathy symptoms. Low-intensity aerobic therapy adds to the quality of life of the patient, and increases in strength of the lower limbs show an improvement in foot sensation and a reduction in pain and tingling symptoms.

Charcot neuroarthropathy patient education among podiatrists in Scotland: a modified Delphi approach.

BACKGROUND: This evaluation sought to determine current Charcot neuroarthropathy (CN) diabetes patient education practices among Scottish National Health Service (NHS) and academic podiatrists and evaluate novel visual tools and develop expert consensus for future practice. METHODS: Questionnaires collected mixed qualitative and quantitative responses, analysed concurrently within a convergence coding matrix. Delphi methodology permitted member-checking and agreement of consensus over two rounds. RESULTS: Fourteen participants (16.28%) completed a Round One questionnaire, leading to the generation of four themes; Experience; Person-Centred Care and the Content and Context of CN patient education. Seven consensus statements were subsequently developed and six achieved over 80% agreement among 16 participants (18.60%) with a Round Two questionnaire. Respondents agreed CN patient education should be considered for all 'At-risk' individuals with diabetic peripheral neuropathy (DPN). Verbal metaphors, including the 'rocker-bottom' foot, soft or brittle bones, collapsing, walking on honeycomb and a shattering lightbulb were frequently employed. Visual tools, including visual metaphors and The Charcot Foot Thermometer, were positively evaluated and made available online. CONCLUSIONS: Key findings included respondent's belief that CN education should be considered for all individuals with DPN and the frequent use of simile, analogy and metaphor in CN education. The concept of 'remission' proved controversial due to its potential for misinterpretation.

The effects of vibro-medical insole on sensation and plantar pressure distribution in diabetic patients with mild-to-moderate peripheral neuropathy.

BACKGROUND: The first aim of this study was to determine the effect of a vibro-medical insole on pressure sensation and the second was to measure the effects of a vibro-medical insole with and without random noise on plantar pressure distribution in diabetic patients with mild-to-moderate peripheral neuropathy. METHODS: Twenty patients with mild-to-moderate diabetic neuropathy were recruited in the clinical trial pre-test, post-test study. A medical insole was made for each participant and a vibratory system was inserted into it. Pressure sensation was evaluated before and after the 30-min walk using the vibro-medical insole with added random noise by Semmes-Weinstein Monofilaments. Peak pressure data was measured before and after 30-min walking with a vibro-medical insole with and without random noise by the Pedar-x system. FINDINGS: Pressure sensations showed improvement after 30-min walking with the vibro-medical insole with added random noise at the heel, metatarsophalangeal heads and hallux of both feet in all participants (p < 0.05). Peak pressure decreased significantly in the heel, MTP2,3, MTP4,5 and hallux (p < 0.05) and increased in midfoot (p < 0.05) using the vibro-medical insole with and without random noise compared to the shoe only condition. Only the peak pressure of the heel region decreased using the vibro-medical insole with random noise compared to without random noise (p = 0.006). INTERPRETATION: Thirty minute walking with a vibro-medical insole seems to improve pressure sensation and alter peak pressure in diabetic patients with mild-to-moderate peripheral neuropathy. This work suggests that vibro-medical insoles can be used for daily living activities and possibly decreases the risk of ulceration in diabetic neuropathy patients.

The Effectiveness of Aerobic Exercise in Improving Peripheral Nerve Functions in Type 2 Diabetes Mellitus: An Evidence Based Case Report.

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.
