Objective To investigate whether an internet-based neck-specific training program can alleviate pain and disability in participants with cervical spondylotic radiculopathy (CSR). Methods Patients diagnosed with CSR at West China Hospital of Sichuan University between March 2022 and September 2022 were randomly allocated to either an telehabilitation group or a traditional treatment group. The primary outcome measures included Visual Analogue Scale, Neck Disability Index, and patient satisfaction. Secondary outcome measures included the Euroqol group’s 5-Domain questionnaire, Fear-Avoidance Beliefs Questionnaire, Hospital Anxiety and Depression Scale, Tanaka Jingjiu cervical spondylosis symptom scale (20 points) and satisfaction. Quantitative outcome measures were collected at baseline, 12th and 24th weeks after the first intervention, while qualitative outcome measures were collected at 24th weeks after the first intervention. Results A total of 90 patients were included, with 45 in each group. There was no statistically significant difference between the two groups in terms of age, gender and other demography characteristics and general data (P>0.05). There is no interaction effect (group × time) for the Tanaka Jingjiu cervical spondylosis symptom scale (20 points) (P>0.05), the interaction effects (group × time) for other quantitative outcome measures were statistically significant (P<0.05). The time effect showed significant statistical differences across all quantitative outcome measures (P<0.001), while the group effect did not exhibit any significant statistical differences (P>0.05). The comparison results within the group showed that at different time points, the differences between the two groups were statistically significant (P<0.001). There were no significant statistical differences between the two groups in terms of qualitative outcome measures (P>0.05) . Conclusions An internet-based neck-specific training program or traditional treatment for 12 weeks can effectively reduce pain and disability among CSR patients, with significant long-term effects. There was no significant difference in treatment effectiveness between the two groups.
