(2) Methods: The study included fifteen patients aged 60\u201370 years (13 women and 2 men). The comparison group consisted of 15 healthy subjects (12 women and 3 men) aged 60\u201369 years. The study included measurement of peak torque (PT) and the range of motion of the shoulder joint, assessed using the Biodex System 4 Pro set, and an electronic goniometer. We conducted tests at two different angular velocities (60\u00b0\/s and 90\u00b0\/s), taking into account the operated and non-operated limb and comparing the results to healthy subjects. The average time from surgery to functional examination was 16 months. (3) Results: The non-operated limb generated significantly higher PT values than the operated limb (p &lt; 0.001). The healthy limb of patients from the comparison group generated significantly higher PT values than the operated limb of patients from the study group (p &lt; 0.001). A significant improvement (p &lt; 0.001) in the range of motion in the operated limb was achieved after rTSA. (4) Conclusions: In patients 18 months after the rTSA, the non-operated upper limb has significantly greater muscle strength in flexion\/extension and abduction\/adduction movements compared to the operated limb. The non-operated limb also has a significantly greater range of motion compared to the operated limb.<\/jats:p>","DOI":"10.3390\/jcm12237351","type":"journal-article","created":{"date-parts":[[2023,11,27]],"date-time":"2023-11-27T11:54:48Z","timestamp":1701086088000},"page":"7351","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Assessment of Isokinetics and Range of Motion of the Shoulder in Patients after Reverse Shoulder Arthroplasty in the Late Follow-Up Period"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3714-3676","authenticated-orcid":false,"given":"Katarzyna","family":"Ogrodzka-Ciechanowicz","sequence":"first","affiliation":[{"name":"Institute of Clinical Rehabilitation, Faculty of Motor Rehabilitation, University of Physical Education, 31-571 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr","family":"Kurzeja","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences, University of Applied Sciences in Nowy Targ, 34-400 Nowy Targ, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Sorysz","sequence":"additional","affiliation":[{"name":"Trauma and Orthopedic Unit, Gabriel Narutowicz Municipal Specialist Hospital in Krakow, 31-215 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1302\/2058-5241.6.200085","article-title":"An update on reverse total shoulder arthroplasty: Current indications, new designs, same old problems","volume":"6","author":"Kozak","year":"2021","journal-title":"EFORT Open Rev."},{"key":"ref_2","first-page":"e20.00156","article-title":"Prevalence of Shoulder Arthroplasty in the United States and the Increasing Burden of Revision Shoulder Arthroplasty","volume":"6","author":"Farley","year":"2021","journal-title":"JBJS"},{"key":"ref_3","first-page":"399","article-title":"Factors Predicting Postoperative Range of Motion and Muscle Strength one Year after Shoulder Arthroplasty","volume":"9","author":"Alsubheen","year":"2021","journal-title":"Arch.
