Short-term effects of dry needling of thenar muscles in manual laborers with carpal tunnel syndrome: a pilot, randomized controlled study.

STUDY DESIGN: Pilot, randomized, single-blinded controlled clinical trial. BACKGROUND AND OBJECTIVE: Trigger point (s) (TrPs) in thenar muscles could be a cause of narrowing of carpal tunnel in manual laborers with carpal tunnel syndrome (CTS). Effects of dry needling (DN) on the treatment of muscle tension have been reported, but no research has been done on the effect of DN on thenar tight muscles on reducing CTS symptoms. The aim of this study was to assess the effect of DN of thenar muscles TrPs in the treatment of mild-to-moderate carpal tunnel syndrome. METHODS: Thirty manual laborers with mild-to-moderate CTS and the presence of TrP(s) in thenar muscles were randomized to DN group (n = 15) and control group (waiting list) (n = 15). The DN group received 2 sessions of DN of thenar muscles TrP(s), with a 48-h interval. The control group received no treatment. Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) scores were the primary outcome, while secondary outcomes included electrophysiological domains, pinch and grip strength. Outcome measures were obtained at baseline, 48 hours, and 2 weeks after treatment (follow-up). Two-way analysis of variance (2 groups × 3 times) was used to compare within- and between-group differences. Bonferroni post hoc test was used to find any significant differences in the main effect for group, time, or interaction (group time). RESULTS: A baseline assessment revealed no intergroup differences in all evaluated parameters (P > .05). Compared to the control group, the DN group had a statistically significant improvement in pinch and grip strength, median SDL, and BCTQ score after 2 weeks (P < .05). There were no between-group differences in the assessment of motor electrophysiologic and SNCV findings (P > .05). CONCLUSION: Dry needling of thenar TrP(s) is effective in short-term improvement of function in manual laborers with mild-to-moderate CTS.

The Effect of Dry Needling on Pain, Range of Motion of Ankle Joint, and Ultrasonographic Changes of Plantar Fascia in Patients With Plantar Fasciitis.

CONTEXT: Plantar fasciitis (PF) is a common and devastating disease. Despite different treatments, there is no clear evidence for the effect of these treatments on PF. One of the therapy methods used in physiotherapy is dry needling (DN). So the purpose of this study is to investigate the effect of DN on the pain and range of motion of the ankle joint and plantar fascia thickness in subjects with PF who are suffering from the trigger points of the gastrocnemius and soleus muscles. METHODS: In this study, 20 volunteer females with PF were randomly assigned into DN treatment and control groups. Measurements were range of motion in dorsiflexion and plantar flexion, plantar fascia thickness, and visual analog scale measured before, immediately, and 1 month after the end of the intervention in both groups. RESULTS: There were significant differences in the plantar fascia thickness and visual analog scale between the 2 groups. Plantar fascia thickness (P = .016) and visual analog scale (P = .03) significantly decreased in the treatment group. However, there was no significant difference in plantar flexion (P = .582) and dorsiflexion range of motion (P = .173) between groups. CONCLUSION: The result of this study showed that DN can reduce pain and plantar fascia thickness in women with PF who are suffering from trigger points of the gastrocnemius and soleus muscles. LEVEL OF EVIDENCE: Level 1, randomized controlled trial.

The effects of acupressure on the symptoms severity and function status and electrodiagnostic findings in patients with carpal tunnel syndrome.

OBJECTIVE: This study aimed to evaluate the effects of acupressure on the symptoms severity, function status and electrodiagnostic findings in patients with Carpal tunnel syndrome (CTS). DESIGN: This double blind, randomized, controlled clinical trial study was conducted on 57 patients with CTS that selected through convenience sampling. The patients were randomly assigned to three groups, including (1) acupressure; (2) placebo acupressure; and (3) control. SETTING: The study was conducted in the medical centers affiliated to Semnan University of Medical Sciences, Iran. INTERVENTION: The intervention groups received acupressure or placebo for one month. The control group received only routine cares (splints and analgesics) with no additional intervention. PRIMARY OUTCOMES: The severity of symptoms and hand function were evaluated by the Boston Carpal Tunnel Syndrome Questionnaire, and electrodiagnostic findings, including Nerve Conduction Velocity (NCV), Distal Sensory Latency (DSL), and Distal Motor Latency (DML) were measured by Electromyography device before and after the intervention. RESULTS: The results showed significant differences in the mean severity of symptoms, hand function, NCV, DSL, and DML before and after the intervention in the acupressure group (P < 0.05). Significant differences were also observed between the means difference in severity of symptoms, hand function, and NCV, DSL, and DML before and after the intervention in the three groups (P < 0.05). CONCLUSION: According to the results, acupressure was effective in reducing the severity of clinical symptoms, improving the hand function, and improving the electrodiagnostic findings. Therefore, the application of acupressure can be recommended for improving clinical symptoms of patients with CTS.
