Modified prolotherapy by 5% dextrose: Two years experiences of a traditional and complementary medicine practice center in Turkey

Comparative Efficacy of 5% Dextrose and Corticosteroid Injections in Carpal Tunnel Syndrome: A Systematic Review and Meta-analysis

OBJECTIVE

This study aims to assess the effectiveness of 5% dextrose (D5W) in comparison to corticosteroids for treating carpal tunnel syndrome (CTS).

DATA SOURCES

A comprehensive systematic search was conducted across MEDLINE (PubMed), Embase, and the Cochrane Central Register of Controlled Trials on November 13, 2023. These were supplemented by manual searches using Google Scholar.

STUDY SELECTION

Two independent authors reviewed the literature, resolving any discrepancies through detailed discussions and consultation with a third author.

DATA EXTRACTION

Data on primary outcomes (pain assessment) and secondary outcomes (symptom severity and functional status using the Boston Carpal Tunnel Questionnaire, electrophysiologic measures, cross-sectional area, and adverse effects) were extracted independently by the 2 authors (M.W. and H.H.).

DATA SYNTHESIS

The analysis included 4 randomized controlled trials and 1 quasi-experimental study, encompassing a total of 212 patients (220 hands) with mild to moderate CTS.

RESULTS

Within 3 months, the D5W injections showed a statistically significant improvement in functional status compared to the corticosteroids with a standard mean difference of -0.34 (95% CI, -0.62 to -0.05). D5W was associated with fewer adverse incidents than corticosteroids (risk ratio, 0.13; 95% CI: 0.03-0.51). No difference was observed between the 2 treatments in other areas.

CONCLUSIONS

For patients with mild to moderate CTS, D5W injections were more effective than corticosteroid injections in improving functional status and demonstrated fewer adverse effects. D5W injections also paralleled corticosteroids in pain reduction, symptom severity, electrodiagnostic measures, and cross-sectional area of nerve, recommending D5W as a preferred treatment for mild to moderate CTS.

Is Low-Dose Dextrose Prolotherapy as Effective as High-Dose Dextrose Prolotherapy in the Treatment of Lateral Epicondylitis? A Double-Blind, Ultrasound Guided, Randomized Controlled Study

OBJECTIVES

To investigate the effects of prolotherapy (PrT) on pain, functionality, clinical improvement and to compare the 5% low and 15% high dose dextrose PrT in chronic lateral epicondylitis.

DESIGN

A double-blind, parallel groups, randomized controlled study.

SETTINGS

Outpatient Clinic.

PARTICIPANTS

Sixty patients (N=60), aged 44.30±10.31 years old, with chronic lateral epicondylitis were allocated randomly into 3 groups.

INTERVENTIONS

To Group 1 5% dextrose PrT, to Group 2 15% dextrose PrT, to Group 3 0.9% saline injections were done at 3 times (weeks 0, 3, 6), to the entheses of forearm extensors and annular ligament.

MAIN OUTCOME MEASURES

The primary outcomes were handgrip strength, visual analog scale-rest (VAS-R), visual analog scale-activity (VAS-A), pressure-pain threshold, and Quick Disability of the Arm, Shoulder and Hand (Q-DASH). The secondary outcomes were clinical improvement (Disease Global Assessment Questionnaire), side effects, and complications. Primary outcomes were collected at baseline week 0, week 3, and 12. Secondary outcomes were collected at weeks 3 and 12.

RESULTS

In Group 2, VAS-A and VAS-R (at week 3), handgrip strength and pressure-pain threshold (at week 12) were significantly different than other groups (P<.05). In Groups 1 and 2, there was a difference in primary outcomes at week 12 than baseline (P<.05). In Group 3, there was no difference in VAS-R, VAS-A, and handgrip strength at weeks 3 and 12 than baseline (P>.05).

CONCLUSION

In chronic lateral epicondylitis, 5% and 15% dextrose PrT is more effective in pain, handgrip strength, functionality, and clinical improvement than %0.9 saline. There was no difference in functionality, clinical improvement, side effects, and complications between the PrT groups. 15% dextrose PrT was more effective in handgrip strength and pressure-pain threshold at week 12 and pain at week 3. We recommend 15% dextrose PrT based on this study.
