This study examined muscular strength before and after operation in a group of eight patients with hyperparathyroidism and in a control group of seven patients with benign thyroid lesions. The maximum power grip, pronation and supination, and endurance for the same muscular movements, were studied by means of a computer program. Patients with hyperparathyroidism had impaired muscular strength compared with the controls but 12 months after operation a significant improvement of all muscular performance was observed. No such improvement was detectable among the controls. There was no correlation between the levels of serum calcium and parathyroid hormone and the measurements recorded before and after operation. Muscular impairment in hyperparathyroidism is measurable by an objective technique. Improvement occurs after surgery.<\/jats:p>","DOI":"10.1002\/bjs.1800790223","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T16:59:42Z","timestamp":1172941182000},"page":"165-168","source":"Crossref","is-referenced-by-count":45,"title":["Muscle strength is improved after parathyroidectomy in patients with primary hyperparathyroidism"],"prefix":"10.1093","volume":"79","author":[{"given":"A","family":"Kristoffersson","sequence":"first","affiliation":[{"name":"Department of General Surgery, University Hospital of Ume\u00e5 , Ume\u00e5,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Bostr\u00f6m","sequence":"additional","affiliation":[{"name":"Department of Hand Surgery, University Hospital of Ume\u00e5 , Ume\u00e5,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T","family":"S\u00f6derberg","sequence":"additional","affiliation":[{"name":"Department of Hand Surgery, University Hospital of Ume\u00e5 , Ume\u00e5,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[1992,2,1]]},"reference":[{"key":"2024092810422499600_bib1","first-page":"491","article-title":"Indications for surgery in the elderly patient with primary hyperparathyroidism","volume":"142","author":"Alveryd","year":"1976","journal-title":"Acta Chir Scand"},{"key":"2024092810422499600_bib2","doi-asserted-by":"crossref","first-page":"182","DOI":"10.7326\/0003-4819-80-2-182","article-title":"Neuromuscular disease in primary hyperparathyroidism","volume":"80","author":"Patten","year":"1974","journal-title":"Ann Intern Med"},{"key":"2024092810422499600_bib3","first-page":"135","article-title":"Hyperparathyroidism in the old age","volume":"72","author":"Tibblin","year":"1983","journal-title":"Ann Chir Gynaecol"},{"key":"2024092810422499600_bib4","first-page":"521","article-title":"Improvement of muscle strength after treatment for hyperparathyroidism","volume":"150","author":"Hedman","year":"1984","journal-title":"Acta Chir Scand"},{"key":"2024092810422499600_bib5","doi-asserted-by":"crossref","first-page":"233","DOI":"10.1111\/j.0954-6820.1986.tb02756.x","article-title":"Increase in muscular strength following surgery for primary hyperparathyroidism","volume":"220","author":"Wers\u00e4ll-Robertson","year":"1986","journal-title":"Acta Med Scand"},{"key":"2024092810422499600_bib6","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1002\/bjs.1800750128","article-title":"Maximal isokinetic muscle strength in patients with primary hyperparathyroidism before and after parathyroid surgery","volume":"75","author":"Joborn","year":"1988","journal-title":"Br J Surg"},{"key":"2024092810422499600_bib7","doi-asserted-by":"crossref","first-page":"74","DOI":"10.5694\/j.1326-5377.1988.tb120508.x","article-title":"Neuromuscular symptoms in elderly patients with hyperparathyroidism: improvement with parathyroid surgery","volume":"149","author":"Delbridge","year":"1988","journal-title":"Med J Aust"},{"key":"2024092810422499600_bib8","first-page":"415","article-title":"Pre- and postoperative respiratory muscle strength in primary hyperparathyroidism","volume":"154","author":"Kristoffersson","year":"1988","journal-title":"Acta Chir Scand"},{"key":"2024092810422499600_bib9","first-page":"11","article-title":"Surgery for primary hyperparathyroidism.
