Abstract

Objective: Capacitive and resistive electric transfer therapy (CARE) reduces pain and improves quality of life for many orthopaedic degenerative and inflammatory disorders. The research aim was to determine the effects of CARE on painful shoulder. The outcomes were pain reduction and recovery of shoulder function.

Methods: A retrospective, observational case-control study was conducted. Participants were 46 patients (22 in the CARE group and 24 in the SHAM group). Clinical data, pain (visual analogic scale, VAS) and functional scale scores (Disabilities of the Arm, Shoulder and Hand scale, and Constant-Murley Scale) were measured at baseline T0 (before treatment), T1 (after treatment) and follow-up T2 (2 months after the end of the treatment).

Results: VAS scores in the CARE group improved from 7.23 ± 1.11 at baseline to 2.68 ± 0.99 at follow-up. The SHAM group did not experience any improvement. Similarly, functional scale scores improved in the CARE group compared with the SHAM group.

Conclusion: Considering the small number of sessions needed, low cost and long-term benefits, CARE could be a useful therapeutic option for the conservative management of shoulder pain to restore pain-free and powerful movement to the shoulder joint.

Keywords: Diathermy; capacitive and resistive electric transfer therapy; case-control study; rehabilitation; shoulder pain; thermotherapy.
