(28) The number of the patients was 193, 86 male and 107 female. The average age was 63.5 years and the average period of muscle cramps was 2.14 years.

(29) The number of the “trigger point injection group (control group)” patients was 61, 25 male and 36 female. The average age was 64.6±11.1 years and the average period of muscle cramps was 2.16±1.60 years. The muscle cramps occurred in the lower leg for 53 people, in the hand for 5 people, in the lower leg and hand for 2 people and in the thigh for one person.

(30) The number of the “choline alfoscerate intravenous administration group (Example 1)” patients was 68, 31 male and 37 female. The average age was 63.3±9.89 years and the average period of muscle cramps was 2.16±1.48 years. The muscle cramps occurred in the lower leg for 62 people, in the hand for 2 people, in the hand and foot for 2 people and in the arm and thigh respectively for one person.

(32) 2. Treatment of Test Groups

(33) The “trigger point injection group (control group)” patients were injected with 5 mL of 0.5% lidocaine at the trigger points (4-5 points), once a week.

(34) The “choline alfoscerate intravenous administration group (Example 1)” patients were intravenously injected slowly with choline alfoscerate (1 g/4 mL) mixed in 100 mL of physiological saline, twice a week.

(35) The “choline alfoscerate oral administration group (Example 2)” patients were injected with choline alfoscerate (400 mg/capsule), 3 times a day.

(36) 3. Test Method

(37) The test period was one month. The former two weeks was denoted as T1 and the latter two weeks was denoted as T2. Pain intensity and frequency of cramps for a week were measured. The pain intensity was evaluated according to the 11-point pain intensity numerical rating scale (PI-NRS), where 0=no pain, weakest pain=1 and most severe pain=10. 2-point reduction in the pain intensity was considered clinically significant as reported (Farrar 2001, Rowbotham 2001, Hawker 2011). The pain intensity was measured on the first visit and was compared with the pain intensity 2 weeks (T1) and 4 weeks (T2) after the first drug administration.

(38) For the frequency of muscle cramps, the frequency of muscle cramps for a week before the first drug administration was compared with the frequency of muscle cramps for a week before the visit on the weeks 2 and 4.

(39) Statistical analysis was conducted using the SASS package ver. 23 and significance was tested by the paired t-test.

(40) 4. Test Result

(41) The therapeutic effect for muscle cramps for the “trigger point injection group (control group)”, the “choline alfoscerate intravenous administration group (Example 1)” and the “choline alfoscerate oral administration group (Example 2)” is shown in Table 4.

(42) TABLE-US-00004 TABLE 4 Before drug admini- T1 (first 2 T2 (second 2 stration weeks) weeks) Control Pain intensity 5.34 ± 0.87 3.74 ± 0.91* 2.11 ± 0.76* group Frequency of 2.84 ± 0.99 2.00 ± 0.68* 1.43 ± 0.53* (TPI) muscle cramps Example 1 Pain intensity 6.50 ± 1.26 2.56 ± 1.49*.sup.# 1.32 ± 0.91*.sup.# (choline Frequency of 4.91 ± 2.40 1.56 ± 1.34*.sup.# 0.88 ± 1.19*.sup.# alfoscerate, muscle cramps intravenous) Example 2 Pain intensity 6.31 ± +0.94 3.94 ± 1.17* 1.88 ± 0.92* (choline Frequency of 5.25 ± 1.47 2.67 ± 1.07*.sup.# 1.05 ± 0.70*.sup.# alfoscerate, muscle cramps oral) *P < 0.05: significant difference at T1 or T2 from as compared to before drug administration (trigger point injection, choline alfoscerate intravenous administration or choline alfoscerate oral administration) .sup.#P < 0.05: significant difference of Example 1 or Example 2 as compared to control group at T1 or T2

(43) The pain intensity decreased significantly for the “trigger point injection group (control group)”, from 5.34 points before drug administration to 3.74 points at 2 weeks after the first drug administration (T1) and to 2.11 points at the second 2 weeks, i.e., at 4 weeks after the first drug administration (T2). For the “choline alfoscerate intravenous administration group (Example 1)”, the pain intensity decreased significantly from 6.50 points before drug administration to 2.56 points at T1 and to 1.32 points at T2. For the “choline alfoscerate oral administration group (Example 2)”, the pain intensity decreased significantly from 6.31 points before drug administration to 3.94 points at T1 and to 1.88 points at T2.

(44) The “choline alfoscerate intravenous administration group (Example 1)” showed significant decrease in the pain intensity as compared to the “trigger point injection group (control group)” at both T1 and T2.

(45) The frequency of muscle cramps for a week decreased significantly for the “trigger point injection group (control group)”, from 2.84 times before drug administration to 2.00 times at T1 and to 1.43 times at T2. For the “choline alfoscerate intravenous administration group (Example 1)”, it decreased significantly from 4.91 times before drug administration to 1.56 times at T1 and to 0.88 time at T2. For the “choline alfoscerate oral administration group (Example 2)”, it decreased significantly from 5.25 times before drug administration to 2.67 times at T1 and to 1.05 times at T2.

(46) The “choline alfoscerate intravenous administration group (Example 1)” showed significant decrease in the frequency of muscle cramps for a week as compared to the “trigger point injection group (control group)” at T1. The “choline alfoscerate oral administration group (Example 2)” showed significant increase in the frequency of muscle cramps for a week as compared to the “trigger point injection group (control group)” at T1.

(47) In addition, the “choline alfoscerate intravenous administration group (Example 1)” and the “choline alfoscerate oral administration group (Example 2)” showed significant decrease in the frequency of muscle cramps as compared to the “trigger point injection group (control group)” at T2.

(48) The reason why the “choline alfoscerate oral administration group (Example 2)” showed higher frequency of muscle cramps for a week as compared to the “trigger point injection group (control group)” at T1 may be because the patients of the “choline alfoscerate oral administration group (Example 2)” had much higher frequency of muscle cramps before the drug administration. Despite this difference in patients, the frequency of muscle cramps for a week decreased significantly as compared to the “trigger point injection group (control group)” at T2.

(49) Both the “choline alfoscerate intravenous administration group (Example 1)” and the “choline alfoscerate oral administration group (Example 2)” showed remarkably decreased pain intensity and frequency of muscle cramps and some patients reported that the muscle cramps disappeared the next day after the drug administration. In addition, the patients showed higher compliance to the intravenous injection than the injection directly to the site of muscle cramps.

(50) The “choline alfoscerate intravenous administration group (Example 1)” and the “choline alfoscerate oral administration group (Example 2)” showed no side effect after the treatment. Because choline alfoscerate has no effect on the kidney and liver, it is thought that it can be used for people with kidney or liver problems as a therapeutic agent for muscle cramps.

(51) Hereinafter, the preparation examples of a pharmaceutical composition for treating or preventing muscle cramps or a health functional food composition for improving muscle cramps, which contains choline alfoscerate as an active ingredient, of the present disclosure are described. However, the examples are provided as specific examples only and are not intended to limit the present disclosure.
