Evaluation of the efficacy of warm salt water foot-bath on patients with painful diabetic peripheral neuropathy: A randomized clinical trial

The effect of lavender foot baths on postoperative pain and sleep quality in comparison with foot baths with warm water only-A prospective randomized controlled study

INTRODUCTION

The aim of the study was to investigate the effect of warm water (WW) foot bath with or without lavender oil for pain and sleep quality in the patients who undergone abdominal surgeries.

MATERIALS AND METHOD

This study was designed as a prospective randomized controlled. The three study groups were defined as the control group (n = 44), the WW foot bath group (n = 46), WW foot bath with the lavender group (n = 40). Foot baths were done for 20 min with 40 °C every night for 3 days after surgery. Visual Analogue Scale and Richard-Campbell Sleep Questionnaire were used during data collection.

RESULTS

A total of 130 patients, mean age 55.99 ±  ± 13.05 years, 66 male (51 %), 103 of whom underwent abdominal surgery, were included in the study. When the patients during the postoperative three days were evaluated, decreased pain score and increased sleep quality both the WW and WW foot bath with lavender groups (p < 0.001). Noise-related sleep quality was detected to be lesser in the control group patients on the 3rd day (p < 0.001).

CONCLUSION

WW foot bath with or without lavender oil is an uncomplicated, economical, and effective complementary therapy to reduce postoperative pain and improve sleep quality. WW foot baths with essential oils are optionally available in clinics and can be used according to patients' preferences.

Topical Nigella sativa L. product: a new candidate for the management of diabetic peripheral neuropathy

BACKGROUND

Diabetic neuropathy is one of the most common complications of diabetes. The synthetic drugs available in the market have side effects and limitations for diabetic patients, the vast majority of whom are in the upper age group. In this regard, based on Persian medicinal sources, Nigella sativa (N. sativa) has proved to have beneficial effects on neuropathic pain and neurological disorders. In this study, the effect of N. sativa is investigated topically in patients with diabetic neuropathy.

METHODS

This study was performed as a double-blind clinical trial on 120 neuropathic patients. The patients were divided into three groups. The first group received a topical N. sativa product as an ointment, the second group was given a topical placebo, and the third received 300 mg gabapentin capsules. The blindness was done in first and second groups. Diabetic neuropathy was assessed before the study using the Michigan Neuropathy Screening Instrument (MNSI). In addition, neuropathy symptoms were evaluated after the trial using the MNSI questionnaire.

RESULTS

The data were elicited from the patients' answers to a number of questions in the Michigan questionnaire. There were statistically significant differences between the group that received the topical N. sativa product and the other two groups in terms of legs and feet numbness (p value = 0.001), burning pain in feet or legs (p value = 0.001), muscle cramps in feet or legs (p value = 0.001), prickling fleeing in feet or legs (p value = 0.001), hurting of the skin when the bed covers touch it (p value = 0.005), aggravated symptoms at night (p value = 0.001) and hurting feelings in the legs when walking (p value = 0.032). However, the three studied groups were not statistically different in distinguishing hot water from cold water.

CONCLUSION

According to the results of this study, the topical use of N. sativa, compared to the current drugs, has acceptable improving effects on diabetic neuropathic patients.

Effects of Footbath on Postoperative Pain and Sleep Quality in Patients With Lumbar Degenerative Disc Disease: A Randomized Controlled Study

ABSTRACT

BACKGROUND: Pain management and good sleep are essential for patients after surgical procedures. This study aimed to evaluate the effects of footbath on postoperative pain severity and sleep quality levels of patients who have undergone degenerative lumbar spine surgery. METHODS: Sixty patients were randomly assigned to the footbath intervention group or the control group. The intervention was a 20-minute footbath in 42°C water before patients fell asleep on the evening of the surgery day. On the morning of the surgery day and the morning of postoperative day, the patient's pain severity and sleep quality scores were obtained using the visual analog scale and the Visual Analog Sleep Scale. RESULTS: There was no significant difference between the pain severity scores of the study groups (P > .05). The sleep quality level of the intervention group was statistically significantly higher than that of the control group (P < .05). CONCLUSION: Consequently, a footbath is effective in increasing sleep quality levels of patients who have undergone degenerative lumbar spine surgery. It may be used as a simple and practical nonpharmacological nursing strategy for improving patients' sleep quality.

A Novel Technique Restores Function while Eliminating Intractable Neuropathic Pain in a 71-Year-Old Diabetic Patient under Challenging Injury Conditions

Background The extent of functional recovery induced in healthy patients by sensory nerve grafts, the clinical “gold standard” technique for repairing peripheral nerves with a gap, is significantly limited by increasing gap length, time between trauma and repair, and patient age. When the values of any two, or all three, variables increase simultaneously, there is little to no recovery. For diabetic patients, even under the best of conditions and without any large variables, the extent of axon regeneration and functional recovery is significantly less, but generally none. Therefore, novel techniques are required that enhance recovery in diabetic patients.

Methods A 12-cm long median nerve gap in the wrist/palm of a 71-year-old male long-term diabetic patient was bridged 1.3 years post nerve injury with a sural nerve graft within a platelet-rich plasma-filled collagen tube.

Results By 2 months post-repair, the patient's level 6 chronic neuropathic pain was permanently eliminated. By 6.75 months, the palm had recovered good sensitivity to stimuli of all sensory modalities, including 4.56 g pressure and less than 15 mm two-point discrimination. Each finger had good motor function of M3–5, with partial to complete sensitivity to stimuli of all sensory modalities and an overall recovery of S3.

Conclusion This technique permanently eliminates severe chronic neuropathic pain while simultaneously inducing good motor and sensory recovery in a long-term diabetic patient, under conditions where recovery is rarely, if ever, seen, even in non-diabetic patients. This technique holds great promise of restoring function to diabetic patients, for whom it is otherwise not possible.

The Interaction of Diabetic Peripheral Neuropathy and Carpal Tunnel Syndrome

BACKGROUND

Diabetes mellitus (DM) increases the risk for carpal tunnel syndrome (CTS) and is associated with its own neuropathic complications. Diabetic peripheral neuropathy (DPN) is a common complication seen in diabetic patients. In this study, we examine the relationship between the severity of DPN and CTS.

METHODS

Type 2 diabetic and control patients (n = 292) were recruited at a clinic visit. The Michigan Neuropathy Screening Instrument (MNSI) questionnaire was used to collect data related to peripheral neuropathy. The MNSI scores were compared for patients with CTS with and without DM in univariable and multivariable analyses. χ2 analyses were performed to quantitatively measure the associations between peripheral neuropathy and the presence of CTS.

RESULTS

Of the 292 patients, 41 had CTS, and 19 of these had both CTS and DM. Of the 138 diabetic patients, 85 had peripheral neuropathy. There was no association between a diagnosis of CTS and an MNSI score indicative of peripheral neuropathy. In the diabetic population, CTS was inversely associated with DPN (P = .017). The MNSI scores between diabetic and control patients with CTS were comparable.

CONCLUSION

The severity of peripheral neuropathy in diabetic patients with and without CTS is comparable. Diabetic patients without peripheral neuropathy have an association with higher incidence of CTS in this study, suggesting that there are disparate mechanisms causing DPN and CTS. Nevertheless, diabetes and CTS are risk factors for developing the other, and future studies should further explore how DPN and CTS differ to tailor patient interventions based on their comorbidities.

Effects of half-body and foot baths on peripheral circulation in healthy adult males: a pilot study

[Purpose] This study aimed to clarify the optimal conditions of warm-water bathing required to improve peripheral circulation. [Participants and Methods] Ten healthy males experienced three warm-water bathing depths (half-body, low-leg, and foot) on different days. Peripheral circulation (earlobe blood flow), tympanic temperature, pulse rate, and blood pressure were measured during each session and compared among the bathing conditions. [Results] In half-body bathing, the relative blood flow of participants increased steeply to a level 2.7-fold higher than the baseline during bathing and rapidly decreased after that. Conversely, the relative blood flow gradually and continuously increased to a level 1.7-fold higher than that at the baseline during low-leg bathing and maintained a similar level after that. The blood flow did not markedly change throughout the experiment in foot bathing. The pulse rate during foot bathing and that during low-leg bathing did not change throughout the observation period, but that of half-body bathing increased considerably. [Conclusion] Rapid changes in pulse rate or blood pressure associated with bathing are considered risky. We suggest that low-leg bathing, rather than the usually adopted half-body bathing, is appropriate for improving peripheral circulation in terms of effectiveness and safety.

Warm-water footbath improves dysmenorrhoea and heart rate variability in college students: a randomised controlled trial

The effect of warm-water footbath in improving dysmenorrhoea has been rarely investigated. The study aimed to examine whether a warm-water footbath effectively reduces dysmenorrhoea pain and improves the autonomic nervous system (ANS) activity. The randomised controlled trial was registered at ClinicalTrials.gov. (NCT04071028) We enrolled college students with dysmenorrhoea in Northern Taiwan from December 1 2013 to June 30 2014, and randomised them into footbath (n = 35, median age 19 years) and control groups (n = 33, 18 years). Pain visual analogue scale and Short-Form McGill Pain Questionnaire were used for pain assessment, while heart rate variability (HRV) was measured to assess ANS function. After the interventions, the footbath group significantly improved ANS activity and reduced pain severity comparing to the control group. Furthermore, the changes in HRV positively correlated with the improvement of pain severity. In conclusion, a warm-water footbath is beneficial in improving the pain severity among college students with dysmenorrhoea.Impact StatementWhat is already known on this subject? Dysmenorrhoea is the most common gynaecological condition affecting 34-94% of young women. The existing conventional therapeutic strategies for dysmenorrhoea have potential adverse events. Among the complementary therapies for pain, the warm-water footbath is a widely used thermal therapy in improving peripheral neuropathy symptoms and improving patients' quality of life. The subjects with dysmenorrhoea associate with significantly altered autonomic nervous system (ANS) activity. However, the association among warm-water footbath, menstrual pain and ANS was rarely investigated previously.What the results of this study add? The randomised controlled trial enrolling 68 college students with dysmenorrhoea found warm-water footbath improved ANS activity and reduced pain severity. Furthermore, the changes in heart rate variability positively correlated with pain severity improvement.What the implications are of these findings for clinical practice and/or further research? A warm-water footbath for 20 minutes on menstruation days 1 and 2 is beneficial in improving pain among college students with dysmenorrhoea.

The effect of salt-water bath in the management of treatment-related peripheral neuropathy in cancer patients receiving taxane and platinum-based treatment

OBJECTIVES

In a clinical setting, patients have been observed to complain of discomfort and to discontinue treatment because of chemotherapy-induced peripheral neuropathy. This experimental study was conducted to determine the effect of a salt-water bath in the management of chemotherapy-induced peripheral neuropathy.

METHOD

One hundred and three patients who received taxane and platinum-based chemotherapy due to cancer and developed peripheral neuropathy associated with the treatment between December 2018 and June 2020 were included in the study. The patients were assigned to the control and experimental groups (1-warm salt-water and 2-cold salt-water) following the randomization checklist. While control groups did not receive any interventions, the patients in the salt-water group were asked to apply warm (41 °C) or cold-water (23-26 °C) baths to their hands/feet for 30 min every other day for 14 days. The data were collected at the beginning of the study and at the end of its first and second weeks using the Patient Information Form and National Cancer Institute (NCI)-CTCAE v5.0 toxicity criteria as well as the EORTC QLQ-C30 and EORTC QLQ-CIPN20 quality of life scales.

RESULTS

The patients had a mean age of 55.6 ± 10.3, and most of them were treated following a breast cancer diagnosis. At the beginning of the study, Grade 3 peripheral neuropathy severity and quality of life scores of the cold/warm salt-water and control groups were similar. Due to repeated follow-ups, it was determined that the peripheral neuropathy severity decreased and the quality of life scores increased statistically significantly in the patients in the cold salt-water bath group compared to the control group.

CONCLUSION

This study's results suggest that a cold salt-water bath can be an effective approach in managing the development of peripheral neuropathy due to taxane and platinum-based treatment.

Thermotherapy Plus Neck Stabilization Exercise for Chronic Nonspecific Neck Pain in Elderly: A Single-Blinded Randomized Controlled Trial

Neck pain is a serious problem for public health. This study aimed to compare the effects of thermotherapy plus neck stabilization exercise versus neck stabilization exercise alone on pain, neck disability, muscle properties, and alignment of the neck and shoulder in the elderly with chronic nonspecific neck pain. This study is a single-blinded randomized controlled trial. Thirty-five individuals with chronic nonspecific neck pain were randomly allocated to intervention (n = 18) or control (n = 17) groups. The intervention group received thermotherapy with a salt-pack for 30 min and performed a neck stabilization exercise for 40 min twice a day for 5 days (10 sessions). The control group performed a neck stabilization exercise at the same time points. Pain intensity, pain pressure threshold (PPT), neck disability index, muscle properties, and alignment of the neck and shoulder were evaluated before and after the intervention. Significant time and group interactions were observed for pain at rest (p < 0.001) and during movement (p < 0.001), and for PPT at the upper-trapezius (p < 0.001), levator-scapula (p = 0.003), and splenius-capitis (p = 0.001). The disability caused by neck pain also significantly changed between groups over time (p = 0.005). In comparison with the control group, the intervention group showed significant improvements in muscle properties for the upper-trapezius (tone, p = 0.021; stiffness, p = 0.017), levator-scapula (stiffness, p = 0.025; elasticity, p = 0.035), and splenius-capitis (stiffness, p = 0.012), and alignment of the neck (p = 0.016) and shoulder (p < 0.001) over time. These results recommend the clinical use of salt pack thermotherapy in addition to neck stabilization exercise as a complementary intervention for chronic nonspecific neck pain control.
