Effectiveness of Ionic Correction along with Conventional Physiotherapy in Patients Recovering from Stroke: A Case Study

Background and Aims: Brain damage caused by stroke is associated with sensorimotor and/or cognitive impairment, depending on area of brain affected and the severity of attack. The aims of this study were to show the importance of physiotherapy associated with electrolyte and mineral balance through diet correction in patients recovering from stroke. Methods: This is a follow-up study of two patients with stroke followed at Kinshasa International Hospital Center during period from May 16 to July 1, 2020. The first had received physiotherapy with foods for correction of the existing ionic and mineral deficiency and the second had only received pharmacological management with conservative physiotherapy without making a change in diet. Clinical and electrolyte monitoring was performed at regular intervals in both patients. The variables of interest evaluated in both patients were FIM, MOTOR/SENSORY and Ionic balance. Results: The parameters of FIM, Conclusion: The results show that


Introduction
Cerebrovascular accident (stroke) is defined according to the World Health Organization as "a sudden deficit of focal brain function with no apparent cause other than a vascular cause" [1]. It is the third leading cause of death and the leading cause of disability in the world [2]. Brain injury is associated with sensorimotor and/or cognitive disorders, depending on the area of the brain affected and the severity of the injury [3] [4]. Initially, these are non-permanent deficits, which tend to decline over time. However, it appears that only one in ten people recover all of their functions, and 40% preserve difficulties in the activities of daily living [5]. Following the accident, three phases can be distinguished: the acute phase which concerns the first 14 days, the subacute phase, from day 14 to month 6 and the chronic phase, after 6 months [6]. The care pathways differ from patient to patient, but hospital treatment from the first symptoms is vitally important. A multidisciplinary care is then put in place, combining medical care and physiotherapy [7]. The hospitalization time is intended to be as short as possible, in favor of a return home, or a structure suitable for physiotherapy and functional recovery [7]. Indeed, the hospital is a gateway for 30% of patients, who require a transfer to Follow-up Care and Rehabilitation [8]. Physiotherapy associated with diet in the management of stroke is a controversial topic in the literature. No study has shown its benefit in the management of stroke in hospitals. In this study, the hypothesis is that physiotherapy associated with electrolyte balance through diet correction is much more effective than simple conventional physiotherapy combined with pharmacological management for the patient recovering from stroke could be demonstrated. It is in this context that we intervened with the two patients suffering from a documented stroke. The aim was to demonstrate the importance of physiotherapy associated with electrolyte and mineral balance through diet correction in patients recovering from stroke.

Patients and Methods
This is a case follow-up study carried out on 2 patients at the Center Hospitalier International de Kinshasa during the period from May 16 to July 1, 2020. Two patients who presented a stroke were included after their informed consent and concomitant follow-up during their hospitalization. The first patient had received physiotherapy combined with foods that can correct the existing ionic and mineral deficiency and the second had only received pharmacological management combined with conservative physiotherapy without changing the diet.
During their follow-up during hospitalization, clinical and electrolyte monitoring was performed at regular intervals in both patients. The variables of interest   (Table 1).
3) DTR (Deep Tendon Reflexes): It indicates the status of reflex recovery of nerve at different stages of the treatment [11].
Check the tendon reflexes using impulses from a reflex hammer to stretch the muscle and tendon. The limbs should be in a relaxed and symmetric position, since these factors can influence reflex amplitude. As in muscle strength testing, it is important to compare each reflex immediately with its contralateral counterpart so that any asymmetric reinforcement procedures. For example, have the patient gently contract the muscle being tested by raising the limb very slightly, or have them when the reflex is tested. When reflexes are very brisk, clonus is sometimes seen. This is a repetitive vibratory contraction of the muscle that occurs in response to muscle and tendon stretch. Deep tendon reflexes are often rated according to the following scale: -0: absent reflex.
According to the US Food And Drug Administration, the salt limit for people without hypertension is 2300 milligrams per day and the limit for individuals with hypertension is 1500 milligrams per day.
A very low-salt food is considered to be one with less than 35 milligrams of sodium per serving, according to the U.S. Food and Drug Administration [12].
We advised the case to eat 1500 mg of salt per day in addition to the mild quantities of salt found naturally in the foods generally consumed while the control is been deprived of this addition of salt.
Statistical analyzes The data obtained were organized and presented in the form of tables and graphs. The chi-square test compared the proportions and Student's t allowed us to compare the electrolyte values of the two patients. The threshold of statistical significance was set at p < 0.05. Data were analyzed using MedCal version 9.1 Open Journal of Therapy and Rehabilitation software. Anonymity, confidentiality and justice were respected during the conduct of this study. Both patients had freely consented to participate in the study.

Results
Two male patients aged 27 for the first and 42 for the second, were included in this case study. The first was on appropriate diet and physiotherapy and conventional medical management (case) and the second was under conventional pharmacological Management and physiotherapy for stroke. Their data reported during inpatient follow-up are illustrated in the figures and tables below. Figure 1 shows that in cases, the FIM improves during follow-up whereas in the control, the FIM is disturbed (decrease) with a statistically significant difference (p = 0.001).

MS (muscle strength-MMT)
In this Figure 2, we note in the case that the parameters of the upper limb increase significantly (p < 0.001) during follow-up, on the other hand in the control, the parameters remain constant.
We also note in this Figure 3 that in the case that the Lower limb parameters increase significantly (p < 0.001) during follow-up, on the other hand in the control, the parameters remain constant without a significant difference during follow-up (p = 0.968).
In this Table 2, the UPPR LIMB and LOWER limb of Deep tendon reflexes were increased in the case and remained zero or weak in the control throughout follow-up. The same superficial and deep sensation changed from non-sensitive to normal in the case and non-sensitive in the control during the course followed even at the end of the study.

Biological Characters
In the case, Na + , Cl − , K + , Ca 2+ , and ionic Ca + improved from intake to discharge.   On the other hand, these biological parameters deteriorated during follow-up in the control (Table 3).
On admission (Day 1), only the K + which was significantly higher in the control than the case (p = 0.011), the other parameters were not different. At discharge (Day 2), a significant drop in K + control was noted

Discussion
Our brain is connected to the rest of the organs and muscles in our body. For example; when our hand moves, the brain sends signals through nerve cells to the muscles in the hand to contract. Nerve cells send out many electrical impulses telling the muscles of the hands to contract. These electrical impulses in nerve cells are known as the action potential. The action potential results from the concentration gradient of the ions (Na + , K + or Cl − ). The three main events triggering an action potential are: depolarization, repolarization and hyperpolarization [12]. During depolarization, the doors of Na + ions are opened. It brings an influx of Na + ions into the cell and as a result the neuronal cell is depolarized.
The action potential passes through the axons. Upon repolarization, the cell returns to the resting membrane potential by stopping the influx of Na + ions, but the K + ions exit the neuronal cell due to the opening of k + ion gates during repolarization. When the action potential crosses K + channels for too long, the neuron loses more K + ions. This results in hyperpolarization of the neuronal cell (more negative than the resting membrane potential). Hyperpolarization is normally due to the efflux of K + ions from the K + channels or the influx of Cl − ions from the Cl channels [12]. Through this study, we even saw the importance of Cl − ions as an alternative to K + ions in returning the membrane potential to its resting state and thus helping to return the hyperpolarized nerve to its resting membrane potential so that it becomes ready for its next cycle of depolarization and muscle contraction. So, by this study, we even support the fact that ions play just as important role as K + ions along with Na 2+ ions in maintaining normal conductivity and contractility of muscles. As we know, Na 2+ ions, K + are very important for the depolarization and repolarization of the nerves and to maintain the normal contraction of the muscles, in the current study we saw a patient to whom a diet rich in these ions showed a and a rapid increase muscle strength and have also shown an improvement in functional independence while others who have been deprived of ionic correction and who have just been followed up with only pharmacological therapy combined with conventional physiotherapy have just shown a drastic drop of its capabilities due to a sudden drop in the content of these ions, so it is evident that these ions play a major role in main- African Americans, and middle-aged and older adults limit their intake to a maximum of 1500 mg of sodium per day and adhere to the potassium recommendation, of 4700 mg/day with a healthy diet of fruits and vegetables. This study specifically showed how these ions are globally responsible for the neurological recovery and well-being of one patient while the other patient worsens due to the deficiency or fall of these ions at the crucial stage of recovery.

Conclusion
Thus, the results obtained from the data collected and analyzed in the 2 subjects clearly show that the ionic balance by diet correction associated with physiotherapy is more effective than conventional physiotherapy associated with pharmacological management. Diet is the best natural alternative to correcting ionic deficiencies than drugs and it has better absorption in the body without side effects.
