Comparison of Different Treatment Approaches in Carpal Tunnel Syndrome

The effectiveness of various external applications (strapping and splinting) on grip strength, pain intensity, symptom level, and functional status in carpal tunnel syndrome (CTS) has been compared in this study. Comparative testing was conducted with exercise and mobilization applications (carpal bone mobilization, yoga, tendon and nerve gliding exercises, neurodynamic mobilization, instrument-assisted soft tissue massage, and standard soft tissue massage) in control groups, placebo groups, and groups undergoing other non-surgical treatments (orthotic application, steroid injections, and other physical agents). Criticisms regarding these studies include bias, lack of blinding, and small intergroup differences. In the literature, evidence supporting the beneficial effects of splinting and strapping applications on CTS is reported to be of low quality, emphasizing the need for higher-quality studies. In light of the information obtained, this study aims to compare the effects of different external applications (strapping and splinting) on grip strength, pain intensity, symptom level, and functional status in CTS.

The inclusion of 40 volunteers is planned for the study. Participants will be divided into four groups, namely control, splint, rigid strapping, and kinesiotape, with the intention of having 10 participants in each group using the closed envelope method.

In the control group (CG), a conventional physiotherapy program will be implemented for 2 weeks. A 10-session treatment will be completed using thermal and electrical agents specified in the program prescribed by the physiotherapist.

In the Splint (SP) group, in addition to the 10-session conventional physiotherapy program, individuals will be instructed to use the splint prescribed by the physician for 2 weeks.

In the Rigid Strapping (RB) group, along with the 10-session conventional physiotherapy program, a rigid strapping application will be performed by an experienced researcher at the end of each physiotherapy session, five days a week.

In the Kinesiotape (KT) group, in addition to the 10-session conventional physiotherapy program, kinesiotape application will be carried out by a certified researcher. To ensure homogeneity, individuals in both strapping groups will be asked to remove the tape before coming to treatment and reapply it at the end of the session. All participants included in the study will be evaluated twice, before and after treatment.
