Does manual lymphatic drainage improve upper extremity functionality in female patients diagnosed with rheumatoid arthritis? A randomized controlled study

Can manual lymphatic drainage be a new treatment option in mild-moderate carpal tunnel syndrome? A randomized controlled study

BACKGROUND

Carpal tunnel syndrome is the most common entrapment neuropathy in the upper extremity, making it essential to assess the effectiveness of various physiotherapy treatments.

PURPOSE

This study aimed to determine the clinical and electrodiagnostic improvement in mild-to-moderate carpal tunnel syndrome patients through manual lymphatic drainage (MLD) versus an orthosis alone.

STUDY DESIGN

This is a prospective randomized controlled study.

METHODS

The sample consisted of a total of 36 patients who met the inclusion criteria. Experimental group received MLD and orthosis, and the control group received only orthosis. The patients were evaluated with electrodiagnostic tests, Visual Analog Scale, algometer measurements (pressure pain threshold), Boston Carpal Tunnel Syndrome Questionnaire before and after treatment. Evaluations were made before and after treatment (4 weeks later).

RESULTS

Boston Carpal Tunnel Syndrome Questionnaire scores improved significantly with both treatment methods in both the experimental (p < 0.001, d = 2.0) and control groups (p < 0.001, d = 1.5). The pressure pain threshold significantly increased in the experimental group at the level of the transverse carpal ligament (p = 0.02, d = 0.86, 95% Confidence Interval (CI) = -0.08 to 1.2). At the distal radioulnar joint and extensor digitorum communis muscle levels, the pressure pain threshold similarly increased for two groups after treatment (p = 0.65, d = 0.31, 95% CI = -0.44 to 1.2), but the post-treatment increase in the experimental group was significant (p = 0.007, d = 0.31). In the experimental group, motor velocity (p = 0.001, d = 0.98), amplitude (p = 0.002, d = 1.5), and latency (p = 0.002, d = 0.60) and sensory velocity (p = 0.03, d = 0.91) and latency (p = 0.001, d = 1.2) significantly improved, while in the control group, there was a significant change only in motor velocity and amplitude (p = 0.047, d = 0.59). The post-treatment sensory improvement was significantly higher in the experimental group (p = 0.01, d = 0.81, 95% CI = -0.78 to -0.49).

CONCLUSIONS

MLD significantly improved sensory conduction velocity, amplitude, and latency of the median nerve. Additionally, MLD and orthosis increased the pain pressure threshold and led to functional improvement.

Level I of evidence does not support manual lymphatic drainage for total knee arthroplasty: a meta-analysis

It is unclear whether manual lymphatic drainage (MLD) following primary total knee arthroplasty (TKA) is effective in reducing pain and swelling and improving knee function. The present study investigated the efficacy of MLD after TKA. The outcomes of interest are the range of motion (ROM), pain (visual analogue scale, VAS), and circumference of the lower leg. This meta-analysis was conducted according to the 2020 PRISMA statement. In November 2023, the following databases were accessed: PubMed, Web of Science, Google Scholar, and Embase, with no time constraint. Only level I evidence studies, according to the Oxford Centre of Evidence-Based Medicine, were considered. All the randomised controlled trials (RCTs) comparing patients who have received MLD versus a group of patients who did not undergo MLD following primary TKA were accessed. Data from four RCTs (197 TKAs) were retrieved. 67% (132 of 197 patients) were women. The mean length of follow-up was 7.0 ± 5.8 weeks. The mean age of the patients was 69.6 ± 2.7 years, and the mean BMI was 28.7 ± 0.9 kg/m2. At baseline, between-group comparability was evidenced in the male:female ratio, mean age, mean BMI, knee flexion, and VAS. No difference was found in flexion (P = 0.7) and VAS (P = 0.3). No difference was found in the circumference of the thigh (P = 0.8), knee (P = 0.4), calf (P = 0.4), and ankle (P = 0.3). The current level I of evidence does not support the use of MLD in primary TKA.
