Does physical therapy and rehabilitation improve outcomes for diabetic foot ulcers?

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.

Management and rehabilitation of moderate-to-severe diabetic foot infection: a narrative review

Diabetic foot is one of the most devastating consequences of diabetes, resulting in amputation and possibly death. Therefore, early detection and vigorous treatment of infections in patients with diabetic foot are critical. This review seeks to provide guidelines for the therapy and rehabilitation of patients with moderate-to-severe diabetic foot. If a diabetic foot infection is suspected, bacterial cultures should be initially obtained. Numerous imaging studies can be used to identify diabetic foot, and recent research has shown that white blood cell single-photon emission computed tomography/computed tomography has comparable diagnostic specificity and sensitivity to magnetic resonance imaging. Surgery is performed when a diabetic foot ulcer is deep and is accompanied by bone and soft tissue infections. Patients should be taught preoperative rehabilitation before undergoing stressful surgery. During surgical procedures, it is critical to remove all necrotic tissue and drain the inflammatory area. It is critical to treat wounds with suitable dressings after surgery. Wet dressings promote the formation of granulation tissues and new blood vessels. Walking should begin as soon as the patient's general condition allows it, regardless of the wound status or prior walking capacity. Adequate treatment of comorbidities, including hypertension and dyslipidemia, and smoking cessation are necessary. Additionally, broad-spectrum antibiotics are required to treat diabetic foot infections.

Rehabilitation of patients after diabetic foot amputation

Background: Diabetic foot is a diabetes-related complication that often requires amputation due to ulcer, necrosis, infection, and wound healing problems. Amputation decreases ambulation ability and worsens the patient’s general condition. Thus, active gait training is important after amputation.Current Concepts: The level of amputation depends on the anatomical position, for example, toe amputation and transfemoral amputation. The impairment of ambulatory function is also determined by the position of amputation. Continuous rehabilitation exercise is encouraged for ambulation before surgery. Wound management and pain control are needed for early rehabilitation exercise after surgery. The maturation of the amputation stump is especially important and needed for prosthesis wearing. If the general condition of the patient permits, muscle strengthening exercises, joint range of motion exercises, and ambulation exercises should be started as soon as possible.Discussion and Conclusion: Sufficient understanding of functional decline after amputation is required. The clear goal of ambulation should be set in consideration of the patient’s general condition and ability to walk before surgery. The ultimate goal of amputation is not only to remove necrosis, ulcers, and infected tissues but also to restore ambulatory function. Thus, expertise and significant effort before and after surgery are required.

Baseline characteristics of infected foot ulcers in patients with diabetes at a tertiary care hospital in Pakistan

OBJECTIVE:

Studies on diabetic foot ulcers (DFU) involving a representative sample of patients in Pakistan are scarce. This study aimed to determine baseline characteristics of infected DFUs in patients hospitalised at the Pakistan Institute of Medical Sciences Islamabad.

METHOD:

In this cross-sectional study, carried out during May 2015 and June 2016, foot ulcer characteristics of patients with DFUs were investigated and documented. From infected DFUs, aerobic bacterial pathogens were isolated, identified and evaluated for antimicrobial susceptibility.

RESULTS:

A total of 214 patients were recruited to the study, 62.6% of which were male, 90.2% were aged ≥40 years, 76.2% had type 1 diabetes and 78.5% had poor glycaemic control at time of presentation to hospital. Most patients had grade 3/moderate ulceration (based on the Wagner and International Working Group on the Diabetic Foot/Infectious Diseases Society of America criteria). Over half of the DFUs (57.9%) were of ≤3 months' duration and 70.1% were ≥3 cm². Of the patients with deep infection grade ulcers, 26.6% underwent amputation, accounting for their prolonged hospital stay (≥20 days). Significant differences were observed between patients with type 1 and type 2 diabetes with DFUs in relation to gender (p≤0.0001), ulcer size (p=0.0421) and duration of hospital stay (p=0.0253). The most significant predictors for lower extremity amputation were osteomyelitis (p=0.0114), retinopathy (p=0.0001) and neuropathy (p=0.0001. Piperacillin/tazobactam was found to be an effective antibiotic against the most commonly isolated Staphylococcus non-aureus (35.48%), Pseudomonas aeruginosa (22.26%), and Staphylococcus aureus (20.96%) species indentified in the DFU infections.

CONCLUSION:

The findings of this study may be helpful in the optimal management and appropriate treatment of patients with infected DFUs.

Avaliação do conhecimento de pacientes diabéticos sobre medidas preventivas do pé diabético em Maringá (PR)

Contexto

O atual envelhecimento da população tem gerado maior predominância de doenças crônicas, como o diabetes, a qual está associada a um risco elevado de complicações crônicas e agudas. Entre essas, o pé diabético (PD) destaca-se por possuir alta incidência e grande poder mutilador.

Objetivo

Avaliar o conhecimento da população diabética das Unidades Básicas de Saúde (UBS) de Maringá (PR) sobre a prevenção do PD.

Métodos

Estudo descritivo, quantitativo, tipo inquérito por entrevista. A população estudada foi composta por 80 portadores de diabetes, cadastrados em UBS de Maringá (PR). A coleta de dados buscou levantar dados sociodemográficos e epidemiológicos, bem como as atitudes de controle do diabetes e do autocuidado para prevenção do PD.

Resultados

Do total de entrevistados, nove não realizavam qualquer tipo de exame para controle do diabetes e a renda mensal predominante foi de até um salário mínimo. O grau de escolaridade e a renda mensal não se mostraram relevantes em relação ao conhecimento de cuidados preventivos do PD e nem uma maior adesão a hábitos de vida saudáveis. O cuidado com o PD tende a melhorar à medida que exista uma compreensão mais clara dos fatores que conduzem à perda do membro e um crescente consenso sobre a gestão de vários aspectos clínicos do cuidado com o pé.

Conclusão

Existe uma falta de aprendizado das medidas preventivas, mesmo nos pacientes com algum nível de instrução, o que induz a uma prática deficiente de cuidados.
