Outcome Measures
Primary Outcomes (1)
Visual Analog Scale (MCS-VAS) Score
This is designed to measure improvements in muscle cramps. MCS-VAS indicates the level to which muscle cramps affect overall daily activity. The score ranges from 0 to 10; 0 indicates no interference and 10 indicates severe interference with overall daily activity. MCS-VAS will be administered by a trained evaluator to reduce recall bias and lack of insight, which can limit subjective assessments. To minimize carryover effects, results reflect the average of the scores taken at the second week of each treatment period.
Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported
Secondary Outcomes (6)
Overall Muscle Cramp Scale (MCS) Score
Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported
Self-reported Cramp Pain Score
Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported
ALSFRS-R Score
Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported
Clinical Global Impression of Changes (CGIC) Score
Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported
ALSAQ-5 (Quality of Life Questionnaire) Score
Assessed at Baseline, Week 2, Week 5, Week 8 and Week 11; Week 2 reported

Treatment sequence TJ-68-Placebo-Placebo-TJ-68
EXPERIMENTALEmploying an N-of-1, crossover design, each participant in the TJ-68 clinical trial will serve as his/her control. The participation will last for 11 weeks - four, 2-week treatment periods with 1-week washout (WO) period between each treatment period. Participants (n=13) will be randomized to the following treatment sequences: TJ-68, placebo, placebo, TJ-68 (1 week WO between each treatment period)
Treatment sequence Placebo-TJ-68-TJ-68-Placebo
EXPERIMENTALEmploying an N-of-1, crossover design, each participant in the TJ-68 clinical trial will serve as his/her control. The participation will last for 11 weeks - four, 2-week treatment periods with 1-week washout (WO) period between each treatment period. Participants (n=13) will be randomized to the following treatment sequences: placebo, TJ-68, TJ-68, placebo (1 week WO between each treatment period)
Interventions
For two periods (one period = 2 weeks) during the 11-week participation, participants will take 2.5 g of TJ-68 for three times per day before meals. It will be administered by dissolving 2.5 g of TJ-68 powder in 1 oz. of lukewarm water.
For two periods (one period = 2 weeks) during the 11-week participation, participants will take 2.5 g of placebo for three times per day before meals. It will be administered by dissolving 2.5 g of the placebo powder in 1 oz. of lukewarm water.
