Objective
To determine whether adding extracorporeal shockwave therapy (ESWT) to conventional treatment enhances pain, function, and electrophysiological functionality in females with carpal tunnel syndrome (CTS).
Methods
One hundred females (25–40 years) diagnosed with CTS were randomly allocated to a control group that received conventional therapy and an experimental group that received the same program augmented with ESWT. Outcome measures included the symptom severity scale (SSS), function severity scale (FSS), pain intensity assessed using the visual analog scale (VAS). In addition, distal sensory latency/distal motor latency (DSL/DML), and sensory nerve conduction velocity/motor nerve conduction velocity (SNCV/MNCV) were measured using a nerve conduction velocity study.
Results
The experimental group exhibited significantly greater improvements in SSS, VAS, DSL, DML, SNCV, compared to controls (all p≤0.05). However, changes in MNCV and FSS were non-significant (p>0.05).
Conclusion
Integrating ESWT into rehabilitation enhances function, pain, and electrophysiological recovery in females with CTS.

Objective
To determine the efficacy of concentric vs. eccentric exercise in improving shoulder function, pain, and tendon characteristics for patients with rheumatoid arthritis and rotator cuff tendinopathy.
Methods
Forty patients with rheumatoid arthritis and rotator cuff tendinopathy were divided into either concentric or eccentric exercise groups, with 20 patients in each group. Patients received 12 sessions at a pace of 3 sessions per week. Shoulder Pain and Disability Index (SPADI), the visual analogue scale (VAS), supraspinatus and subscapularis thickness, echo pixels, and the Disease Activity Score-28-erythrocyte sedimentation rate (DAS-28-ESR) were assessed at baseline and post-treatment.
Results
There was a significant difference between the concentric and eccentric groups regarding SPADI and VAS scores in favor of the eccentric group. However, there was no significant difference between the two groups regarding tendon thickness, echo pixels, or DAS-28-ESR.
Conclusion
Eccentric exercises were more effective than concentric exercises in improving shoulder function and pain intensity. However, neither of the two types of exercises was superior in improving tendon characteristics or disease activity.
