Introduction: The goal of this study was to evaluate the effectiveness of individual exercises performed as classic rehabilitation or a home program on the clinical progression of patients with shoulder stiffness. Based on this information, the secondary goal was to develop a new rehabilitation protocol.
Patients and methods: This prospective, comparative series included 148 cases of shoulder stiffness. There were three treatment groups: T1: classic rehabilitation performed below the pain threshold (58 cases); T2: home program with provocation above the pain threshold (59 cases); T3: home program supervised by a physical therapist (31 cases). The execution, pain level and time spent doing each exercise were compiled for each work session - every day for the first 6 weeks, then every week up to 3 months. Clinical (Constant score) and range of motion evaluations were performed at enrollment, week 6 and month 3.Changes were compared between groups; correlation tests were used to analyse the effectiveness of each exercise during each session.
Results: Other than physical therapy and balneotherapy, classic rehabilitation exercises had a negative effect on clinical progression during the first 3 to 5 weeks (P<0.05), but this did not hinder the occurrence of a slow, continuous clinical improvement (P<0.05). Home programs led to rapid functional progression with improvement directly related to the number of exercises actually performed (P<0.05), however, pain during the day increased and pain at night decreased. Supervision by a physical therapist helped to optimize the home program, with the same result at week 6, but a better result at month 3 (P<0.05).
Conclusions: Based on the results of this study, a new treatment protocol for shoulder stiffness was proposed that combines an intensive patient home program with a well-informed physical therapist, who progressively adds classic rehabilitation techniques when they provide the best treatment value for each exercise. Patient education is the key to treatment success.
