Use of graded Semmes Weinstein monofilament testing for ascertaining peripheral neuropathy in people with and without diabetes.

ABSTRACT: AIMS:To assess peripheral neuropathy (PN) using graded Semmes Weinstein monofilaments (SWMs) and determine factors associated with PN among adult volunteers with and without diabetes. METHODS:Adult volunteers were assessed for distal sensory PN using three graded SWMs. Four PN levels were defined: 0 (no PN; felt all three filaments), 1 (subclinical PN; insensate to 1-g filament), 2 (insensate to 10-g), or 3 (insensate to 75-g). Levels 2-3 were considered clinical PN. Associations with PN were determined using ordinal logistic regression. RESULTS:In 1564 subjects (median age 41.9?years, 50.1% women), PN was subclinical or worse in 68.9% and clinical in 11.2%. Age-sex-race-adjusted prevalence of clinical PN was greater in people with diabetes (15.3%) than without (6.1%; P?

Project description:BackgroundStay-at-home orders associated with the SARS-CoV-2 (COVID-19) pandemic were particularly important for older adults with type 2 diabetes, at risk for severe COVID-19 complications. In response, research shifted to remote telehealth methodology. Study participant interests, equipment needs, and ability to adapt methods to the remote/telehealth environment were unknown. Study purposes to assess (1) resource needs (internet/devices accessibility), (2) future telehealth interests, and (3) ability to adapt common research and clinical measures of glycemic control, physical function, activity measures, and quality of life outcomes to a telehealth setting.MethodTwenty-one participants with type 2 diabetes and peripheral neuropathy were recruited from a longitudinal study (11 female; age: 66.3 ± 8.3 years; DM: 15.1 ± 8.7 years). Technology needs and future telehealth interests were assessed. A glycemic measure (HbA1c), a five-times chair rise, a one-week activity monitor, and surveys (self-efficacy, depression, and balance) were collected. All aspects of the study were completed remotely over email and video/phone call.ResultsTwelve participants used computers; nine used phones for study completion. Participants had the following resource needs: connectivity (n = 3), devices (n = 6), and technical support (n = 12). Twenty people expressed interest in participating in future telehealth studies related to balance, exercise, and diabetes management. Methodological considerations were primarily the need for assistance for participants to complete the home HbA1c test, five-time chair rise, wearable activity monitoring, and surveys.ConclusionsOlder adults with type 2 diabetes and peripheral neuropathy would need technological and personal assistance (connection, device, guidance) to complete a long-term telehealth intervention. Despite technology needs, participants were interested in telehealth interventions.Clinical trialParent study, "Metatarsal Phalangeal Joint Deformity Progression-R01 (NCT02616263) is registered at https://clinicaltrials.gov/.

Project description:BackgroundDiabetic peripheral neuropathy (DPN) is one of the most common complications of diabetes mellitus. The main clinical manifestations of DPN include pain, numbness, paraesthesia, and weakness of the lower limbs which often leads to diabetic foot ulceration, eventually resulting in amputation. Based on Traditional Chinese Medicine theory, moxibustion has a great effect on treating and preventing DPN. However, randomized clinical trials done to evaluate the efficacy of this treatment are still lacking. Hence, this study is carried out to evaluate the effectiveness and safety of moxibustion therapy on diabetic peripheral neuropathy.MethodsThis study will be a pilot, interventional, randomized, 2-armed, parallel, singled-masked, controlled trial. A total of 40 diabetes mellitus patients with peripheral neuropathy will be recruited and assigned randomly into 2 groups (moxibustion group and waiting group) at a 1:1 ratio. This trial consists of an 8-week intervention period and a 4-week follow-up period. During the intervention period, the moxibustion group will take 3 moxibustion sessions per week, whereas no intervention will be done on the waiting group to act as the control group. The outcome will be assessed by an outcome assessor who is unaware of the group assignment. The primary outcome will be pain assessment measured with algometry, Leeds Assessment of Neuropathic Symptoms and Signs pain scale, visual analogue scale, and neuropathy pain scale. The secondary outcome will be an evaluation of functional performance capacity with 6 minutes walking test, evaluation of the Foot and Ankle Ability Measure, and serum HbA1c and albumin levels.DiscussionWe hope that this trial will provide valuable insights on the efficacy of moxibustion in the management of diabetic peripheral neuropathy.Trial registrationClinicalTrials.gov Registry No.: NCT04894461 (URL: https://clinicaltrials.gov/ct2/show/NCT04894461?term=NCT04894461&draw=2&rank=1) Registered on May 20, 2021.

Project description:BackgroundMidfoot and ankle movement dysfunction in people with diabetes mellitus and peripheral neuropathy (DMPN) is associated with midfoot deformity and increased plantar pressures during gait. If midfoot and ankle motion during heel rise and push-off of gait have similar mechanics, heel rise performance could be a clinically feasible way to identify abnormal midfoot and ankle function during gait.Research questionIs midfoot and ankle joint motion during a heel rise associated with midfoot and ankle motion at push-off during gait in people with DMPN?MethodsSixty adults with DMPN completed double-limb heel rise, single-limb heel rise, and walking. A modified Oxford multi-segment foot model (forefoot, hindfoot, shank) was used to analyze midfoot (forefoot on hindfoot) and ankle (hindfoot on shank) sagittal angle during heel rise and gait. Pearson correlation was used to test the relationship between heel rise and gait kinematic variables (n = 60). Additionally, we classified 60 participants into two subgroups based on midfoot and ankle position at peak heel rise: midfoot and ankle dorsiflexed (dorsiflexed; n = 23) and midfoot and ankle plantarflexed (plantarflexed; n = 20). Movement trajectories of midfoot and ankle motion during single-limb heel rise and gait of the subgroups were examined.ResultsPeak double-limb heel rise and gait midfoot and ankle angles were significantly correlated (r = 0.49 and r = 0.40, respectively). Peak single-limb heel rise and gait midfoot and ankle angles were significantly correlated (r = 0.63 and r = 0.54, respectively). The dorsiflexed subgroup, identified by heel rise performance showed greater midfoot and ankle dorsiflexion during gait compared to the plantarflexed subgroup (mean difference between subgroups: midfoot 3°, ankle 3°).SignificancePeople with DMPN who fail to plantarflex the midfoot and ankle during heel rise have difficulty plantarflexing the midfoot and ankle during gait. Utilizing a heel rise task may help identify midfoot and ankle dysfunction associated with gait in people with DMPN.

Project description:IntroductionPeripheral neuropathy is reported in obesity even in the absence of hyperglycaemia.ObjectiveTo compare the prevalence and characterise the phenotype of peripheral neuropathy in people living with obesity (OB) and long-duration type 1 diabetes (T1D).Patients and methodsWe performed a prospective cross-sectional study of 130 participants including healthy volunteers (HV) (n = 28), people with T1D (n = 51), and OB (BMI 30-50 kg/m2) (n = 51). Participants underwent assessment of neuropathic symptoms (Neuropathy Symptom Profile, NSP), neurological deficits (Neuropathy Disability Score, NDS), vibration perception threshold (VPT) and evaluation of sural nerve conduction velocity and amplitude.ResultsPeripheral neuropathy was present in 43.1% of people with T1D (age 49.9 ± 12.9 years; duration of diabetes 23.4 ± 13.5 years) and 33.3% of OB (age 48.2 ± 10.8 years). VPT for high risk of neuropathic foot ulceration (VPT ≥ 25 V) was present in 31.4% of T1D and 19.6% of OB. Participants living with OB were heavier (BMI 42.9 ± 3.5 kg/m2) and had greater centripetal adiposity with an increased body fat percentage (FM%) (P < 0.001) and waist circumference (WC) (P < 0.001) compared to T1D. The OB group had a higher NDS (P < 0.001), VAS for pain (P < 0.001), NSP (P < 0.001), VPT (P < 0.001) and reduced sural nerve conduction velocity (P < 0.001) and amplitude (P < 0.001) compared to HV, but these parameters were comparable in T1D. VPT was positively associated with increased WC (P = 0.011), FM% (P = 0.001) and HbA1c (P < 0.001) after adjusting for age (R2 = 0.547). Subgroup analysis of respiratory quotient (RQ) measured in the OB group did not correlate with VPT (P = 0.788), nerve conduction velocity (P = 0.743) or amplitude (P = 0.677).ConclusionThe characteristics of peripheral neuropathy were comparable between normoglycaemic people living with obesity and people with long-duration T1D, suggesting that metabolic factors linked to obesity play a pivotal role in the development of peripheral neuropathy. Further studies are needed to investigate the mechanistic link between visceral adiposity and neuropathy.
