Muscle cramp is common.1 It can be defined as a sudden painful involuntary maximal contraction of a muscle or muscle group lasting up to ten minutes in a person with no other neurological or muscle pathology. Cramps should be distinguished from tetany due to low plasma concentrations of ionised calcium.

Context:Electrically induced muscle cramps (EIMC) do not last long enough to study many cramp treatments. Increasing stimulation frequency lengthens cramp duration; it is unknown which frequency elicits the longest EIMC.Objective:To determine which stimulation frequency elicits the longest EIMC and whether cramp duration and stimulation frequency are correlated.Design:Randomized, crossover.Setting:Laboratory.Participants:20 participants (12 male, 8 female; age 20.7 ± 0.6 y; height 174.9 ± 1.9 cm; mass 76.6 ± 2.2 kg) with a self-reported history of muscle cramps in their lower extremities within the 6 mo before the study.Interventions:The dominant leg’s tibial nerve was percutaneously stimulated with 2-s-duration electrical stimuli trains starting at a frequency of 4 Hz. After 1 min of rest, stimulation frequency increased in 2-Hz increments until a cramp occurred in the flexor hallucis brevis. The stimulation frequency at which a cramp occurred was termed cramp threshold frequency (TF). Cramp duration was determined using strict clinical criteria (loss of hallux rigidity and return of hallux neutral). On the next 4 consecutive days, participants were stimulated at 5, 10, 15, or 20 Hz above TF, and cramp duration was reassessed.Main Outcome Measures:Cramp TF and duration.Results:Cramp TF was 16.9 ± 5.1 Hz. Cramp duration was longer at 15 and 20 Hz above TF (77.9 ± 37.6 s and 69.5 ± 36.9 s, respectively) than at TF (40.8 ± 34.0 s; P < .05). Cramp duration and TF were highly correlated (r = .90). Conclusions: Stimulating at 15 and 20 Hz above cramp TF produces the longest-lasting EIMC.

Contraction And Relaxation

One of the deep and painful involuntary contractions of skeletal muscle is muscle cramp which takes place during various other conditions. The origin for the cramps that occur during or soon after exercise and the appropriate remedies continue to prove uncertain. Soon after an implant process and forceful workout, past voluntary dehydration cramps occur at many sections. The process of identifying the type of cramp is time consuming and treatment process to cramps is also quite tedious. If not treated at the right time, Muscle cramps may cause vigorous side effects and worsening in day to day physiological activities. The main motive of this vest is to locate and identify the cramp and alert so that further injury can be detected. It would also be helpful in preventing the person from further muscular cramps and other complications. EMG signals which are obtained from adhesive electrodes are amplified by using IC741 (op-amp) with instrumentation amplifier configuration.LM35 temperature sensor is used to monitor the temperature at specified locations. Wherever the cramp occurring possibilities are high. Flex sensor is used to identify the abnormal contraction and relaxation muscles in upper limbs. The three input bio potential signals are fed to the micro controller (Arduino UNO). The main objective of this system is to provide a comfortable vest which would monitor the cramps occurring in athletes whenever it occurs. Therefore with the help of this wearable device muscle cramps occurring at upper limbs can be detected and further injuries, complications such as fractures can be reduced.

In our recent article1 we suggested that there was no proven way of treating simple muscle cramp. In patients who are not helped by mechanical manoeuvres, such as stretching, we thought the evidence favoured quinine bisulphate 300 mg at night. Several readers sent comments; most supported our conclusion, and some quoted early trials.

Introduction: Muscle cramp is a common intradialytic complication observed in hemodialysis patients. Similarly Peripheral arterial disease is a common condition in the hemodialysis population. No study on intradialytic muscle cramp and its association with Peripheral arterial disease is yet reported from Nepal. Methods: Fifty patients with a diagnosis of End Stage Renal Disease who were on hemodialysis were studied over a period of one year. Muscle cramp was defined clinically as contractions of a large muscle group and Peripheral arterial disease was diagnosed on the basis of the ankle –brachial index. Chi square (X2) test was used to determine the association between Intradialytic Muscle cramps and Peripheral Arterial Disease. Results: A total of 50 End Stage Renal Disease patients were analyzed. The mean age of the patient was 49.81±12.63 years. The major causes of End Stage Renal Disease in the study population was Chronic Glomerulonephritis 40 % (n=20). Muscle cramps were present in 26% (n=13) cases. Peripheral arterial disease was present in 30% (n=15) of patients. However there was no statistically significant association between the presence of Intradialytic Muscle cramps and peripheral arterial disease (p value =0.18) Conclusions: Intradialytic Muscle cramps and peripheral arterial disease were common occurrence in end stage renal disease patients on hemodialysis patients, however there was no association between the presence of intradialytic Muscle cramps and peripheral arterial disease.  Keywords: end stage renal disease; intradialytic muscle cramps; peripheral arterial disease.

ABSTRACT:Background:There is an urgent need for new therapeutic options to treat muscle cramps; however, no patient-reported measures exist that capture the entire cramp experience. We conducted a qualitative study to assess the experience of patients suffering muscle cramps, aiming to understand what factors determine the impact cramps have in patients’ lives to guide the development of a patient-centered outcome measure of cramp severity and impact.Methods:We enrolled patients with cramps due to several etiologies, including motor neuron disease, pregnancy-induced cramps, cirrhosis and hemodialysis, and idiopathic and exercise-induced cramps. Patients participated in semistructured interviews about their experiences with muscle cramps and their responses were recorded and transcribed. Data were analyzed with content analysis using data saturation to determine the sample size. We subsequently developed a conceptual framework of cramp severity and overall cramp impact.Results:Ten patients were interviewed when data saturation was reached. The cramp experience was similar across disease and physiological states known to cause muscle cramps. The main themes that compose the overall cramp impact are cramp characteristics, sleep interference, daytime activities interference, and the effect on mental health.Conclusions:This framework will be used to develop a patient-reported outcome of cramp severity and impact.

ObjectiveNo previous study has compared water and oral rehydration solution (ORS) intake after dehydration induced by exercise in the heat for the effect on muscle cramps. The present study tested the hypothesis that water ingestion after dehydration would increase muscle cramp susceptibility, but this would be prevented by ORS ingestion.MethodsTen men performed two bouts of downhill running (DHR; −5%) in the heat (35°C–36 °C) until their body mass was reduced by 2%. Ten minutes after DHR, either spring water or electrolyte water similar to ORS (OS-1®) was ingested in a counter-balanced order on two different days separated by a week. Muscle cramp susceptibility was assessed by a threshold frequency (TF) of electrical train stimulation to induce cramp before, immediately after (0), and 30 and 60 min after the ingestion. Blood samples were taken before, immediately and 80 min after DHR to measure serum electrolyte concentrations.ResultsMuscle cramp susceptibility assessed by TF did not change from baseline to immediately after DHR for both conditions (water: 24.6 ± 2.1 Hz, OS-1®: 24.7 ± 1.4 Hz). TF decreased after water intake by 4.3 Hz (30 min) and 5.1 Hz (60 min post-ingestion), but increased after OS-1®intake by 3.7 and 5.4 Hz, respectively. Serum sodium and chloride concentrations decreased after water intake but maintained after OS-1®intake.ConclusionThese results suggest that water intake after dehydration makes muscles more susceptible to electrical simulation-induced muscle cramp, probably due to dilution of electrolytes, and when OS-1®is consumed, the susceptibility to muscle cramp decreases.

<b><i>Background:</i></b> The purpose of this study was to observe the impact of an internet-based management system on the incidence of intradialytic hypotension (IDH) and muscle cramps in hemodialysis patients. <b><i>Methods:</i></b> The patients, who underwent maintenance hemodialysis in the center from January 2018 to June 2020, were recruited and divided into the pre-intervention group (before operation of the internet-based hemodialysis management system, from January 2018 to December 2018) and intervention group (after operation of the system, from June 2019 to June 2020). The clinical outcomes were compared between groups. <b><i>Results:</i></b> The compound endpoint of &#x3e;1 IDH or muscle cramps happened in 182 patients (61.7%) in the pre-intervention group and 99 participants (30.8%) in the intervention group (relative risk [RR] = 0.50 [95% confidence interval [CI], 0.42; 0.60]). IDH occurred in 122 patients (1–5 episodes in 47 patients, 6–10 episodes in 25 patients, and &#x3e;10 episodes in 50 patients) and 33 patients (30 patients had 1–5 episodes and 3 patients had 6–10 episodes) before and after execution of the internet-based management system, respectively (RR = 0.25 [95% CI, 0.18; 0.35]). The incidence of muscle cramps was significantly decreased (RR = 0.57 [95% CI, 0.45; 0.73]) after the implementation of the system, and the number of patients with 6–10 episodes dropped from 10 to 1. Multivariate analyses also showed significantly lower RRs in the intervention group: 0.29 ([95% CI, 0.20; 0.41]) for IDH and 0.58 ([95% CI, 0.45; 0.74]) for muscle cramps. Compared with the pre-intervention, participants in the intervention group had a large improvement in self-management (<i>p</i> &#x3c; 0.001) and self-efficacy (<i>p</i> &#x3c; 0.001). <b><i>Conclusion:</i></b> The study found that the internet-based hemodialysis management system was effective in reducing the IDH and muscle cramp events and improving self-management. It provided a significant implication for the development and application of internet-based programs in hemodialysis management.

Muscle Cramps

Muscle cramp is common among elderly women. A cramp is a rapid, spontaneous painful contraction of a muscle causing an obvious knot inside the muscle. Cramps occur for a few minutes and are sudden. Stretching of the muscle may relief the cramps. Cramps are painful and may awake patient from sleep, as well as delay from the rest.

Background/Aims: Hemodialysis-associated muscle cramp (HAMC) is a common complication under citrate dialysate (CD) occurring in 30% of cases. Our objectives were to assess the gut microbiota quality, mitochondrial activity, and to investigate their possible relationship with HAMC. Methods: Ten end-stage renal disease patients (78.9 ± 2.1 years) treated by hemodialysis (HD) with CD were enrolled and then classified according to the frequency of HAMCs: “frequent HAMCs group” (n = 5) and “absence of HAMCs group” (n = 5). Gut microbiota quality, mitochondrial activity, and some markers of oxidative stress (OS) were investigated. Results: In patients with cramps, gut microbiota diversity seemed lower and some genera including Helicobacter, Lachnospira, Roseburia, and Haemophilus seemed over-expressed, a significant increase of citratemia and significant lowering mitochondrial function were observed. No difference was observed on the OS markers. Conclusion: This first clinical study revealed a possible dysbiosis of microbiota and a mitochondrial dysfunction into HD patients with cramps under CD compared to patients without cramp.
