Brief Summary:
Introduction :
Prolotherapy is regenerative tissue therapy that is considered to be efficacious in reducing symptoms and morbidity of frozen shoulder, but only a few studies demonstrate the effect of prolotherapy at the biomolecular level, particularly the level of Matrix Metalloproteinase- I (MMP-1), Tissue Inhibitor Matrix Metalloproteinase (TIMP-1), as the biomarkers of cartilage repair.
Objective:
To determine the effect of prolotherapy on MMP-1, TIMP-1, and functional outcomes in frozen shoulder patients
Method:
a double-blind randomized controlled trial study involving participants who had been diagnosed with Frozen Shoulder. History taking, functional outcome assessment, MMP-1, and TIMP-1 were measured. The prolotherapy via intraarticular and extraarticular was performed four times, followed by the evaluation of functional outcome, MMP-1, and TIMP-1 at week 12
Alternative Hypothesis :
Prolotherapy will increase the MMP-1, TIMP-1 levels, and improve functional outcome among Frozen Shoulder patients
Detailed Description:
Design :
Double-blind randomized trial
Randomization :
Simple Randomization generated by an online randomizer
Sample Size :
Difference between two means of primary outcome where
1. mean difference (μ 1 - μ 2 ) = 0.47
2. pool variance = 0.09
3. Z 1-α/2 = 1.95 with type 1 error 5%
4. 1-β = 1.282 with power 90%. Yielding 16 patients for each arm
Detailed Intervention
1. Intervention group: Prolotherapy is given four times (Week 0, Week 2, Week 4, and Week 6)
2. Comparison group: Normal Saline is given four times with a timeframe similar to the intervention group
Injection location
1. Rotator Cuff muscles
2. Intraarticular glenohumeral joint
3. Subacromial bursa
4. long-heap of the biceps tendon
5. Acromioclavicular joint
Statistical analysis :
1. Descriptive statistic to elaborate baseline characteristic
2. Assuming the baseline characteristic between groups are similar, the independent t-test will be conducted to see the differences between group, whereas Mann Whitney will be performed for nonparametric data
3. Difference within-group (baseline and last day) will be measured by paired-t-test or Wilcoxon for non parametric scenario
