ABSTRACT
Objective@#Chronic low back pain (LBP) is a huge social burden, and optimal exercise therapies for chronic LBP patients are continuously being studied. To evaluate the effects of digital intervention on pain and disability in patients with chronic LBP, we performed a prospective cohort study. Method: From February 2020 to January 2021, 25 patients with chronic LBP were recruited. Digital intervention contains education contents and video demonstration for individually prescribed exercise. The exercise prescription was renewed every 4 weeks according to subjects’ condition and accomplishment of exercise. This intervention was performed for more than 30 weeks. The pain intensity was assessed using a numeric rating scale (NRS) while their degree of disability was assessed using the Roland-Morris Disability Questionnaire (RMDQ). The pain intensity and disability was evaluated at short term (8∼20 weeks) and long term (30 weeks). @*Results@#As a result, pain intensity (NRS) decreased significantly over the short term and long term (p<0.05). However, pain related disability (RMDQ score) did not change significantly over the follow-up period (p=0.554). @*Conclusion@#Our findings indicate that online-based digital intervention reduced the intensity of chronic LBP. Further research is needed to identify methods to cost-effectively and consistently manage chronic LBP.
ABSTRACT
Patients with chronic knee pain are common, and symptoms are usually caused by degenerative disorders of the knee joint. Although hypertrophic osteoarthropathy (HOA) is a rare cause of knee pain in patients who visit the department of rehabilitation medicine, clinicians should consider this paraneoplastic syndrome. Herein, we report an uncommon case of hypertrophic pulmonary osteoarthropathy (HPO) in a patient with chronic knee pain who was finally diagnosed with lung cancer. A 49-year-old male was referred to the department of rehabilitation medicine from a local clinic for uncontrolled bilateral knee pain. The plain radiograph and magnetic resonance image (MRI) of the knee showed symmetric periosteal reaction and prepatellar bursitis. For additional evaluation, bone scan was done, and it revealed symmetric linear uptake along the diaphyseal and metaphyseal surfaces of both femurs and tibias, a typical feature of HPO. A plain chest radiograph was taken and showed a mass at the left hilar region. The patient was finally diagnosed with non-small cell lung cancer. After receiving chemotherapy for lung cancer, knee pain improved.
