Hand Osteoarthritis (HOA) is the most common joint disease that affects the finger joints of older adults. Individuals with HOA have decreased handgrip strength and hand function. People with this condition have difficulties in grasping, gripping, twisting, and turning objects in daily living. As the disease advances structural changes such as loss of normal joint space, osteophyte formation, and bony nodules in people with HOA are common. Several investigators have examined the relationship between hand or body anthropometrics and handgrip strength and hand function in healthy diverse populations; however, no previous studies have investigated this association in people with HOA. The purpose of this thesis was to investigate the relationship between body and hand anthropometrics with hand strength and function in people with HOA, encompassing 2 papers. The first manuscript in this thesis was to describe the relationship between body and hand anthropometric variables with hand strength in people with HOA. In addition, it sought to establish the relative contribution among those variables for hand grip and pinch strengths in people with HOA. The second manuscript in this thesis was to describe the relationship between body and hand anthropometric variables with hand function in people with HOA. Further, it examines how anthropometric and demographic factors in combination explain hand function and health status in people with HOA. Finally, the thesis addresses the implications for the studies, limitations, and conclusions. / Thesis / Master of Science (MSc)

<p>UVOD: Artroza &scaron;aka predstavlja jednu od najče&scaron;ćih mi&scaron;ićno-skeletnih bolesti. Manifestuje se bolom, nekada otokom, deformacijom i gubitkom funkcije &scaron;aka. Postoje različita mi&scaron;ljenja o povezanosti osteoartroze (OA) i osteoporoze (OP) kao dva najče&scaron;a skeletna poremećaja. CILJ: istraživanja je da se utvrde faktori rizika za nastanak OA &scaron;aka, uporedi mineralna ko&scaron;tana gustina kod pacijenata sa OA &scaron;aka sa kontrolnom grupom i utvrdi značaj metaboličkog sindroma kod pacijenata sa OA &scaron;aka. MATERIJAL I METODE: Istraživanje je obavljeno u periodu od jedne godine kod bolesnika sa OA &scaron;aka &ndash; eksperimentalna grupa, i u kontrolnoj grupi bez OA. OA &scaron;aka je definisana na osnovu bola, klinički prisutnih deformiteta &scaron;aka kod žena u postmenopauzi starosne dobi od 60-70 godina i radiografskih promena ( drugog do četvrtog stepena prema Kellgren-Lowrencovoj skali). Analizirani su faktori rizika odgovorni za nastanak OA &scaron;aka, povezanost OA &scaron;aka sa snagom stiska &scaron;ake, mineralnom ko&scaron;tanom gustinom i metaboličkim sindromom. Analazirirana je i funkcija &scaron;ake pomoću tri validirana upitnika: Michigan Hand Outcomes Questionnaire (MHQ, Duruoz Hand Indeks (DHI), Health Assessment Questionnaire (PROMIS HAQ). Statistička obrada podataka rađena je u programu SPSS verzija 25. REZULTATI: Prosečna starost pacijentkinja je bila 65,89&plusmn;3,67 godina. Eksperimentalna i kontrola grupa se statistički razlikuju prema porodičnoj anamnezi o strukturnim promenama zglobova &scaron;aka, prema bolnosti &scaron;aka u miru, bolnosti &scaron;aka pri palpaciji, uzdržavanju od pokreta prstiju &scaron;aka, snage stiska &scaron;ake, metaboličkom sindromu( p&lt;0,001). Kao značajni prediktori za nastanak osteoartroze &scaron;aka su se izdvojili pozitivna porodična anamneza o strukturnim promenama za zglobovima &scaron;aka i metabolički sindrom ( p&lt;0,001). Utvrđen je veći broj ispitanica sa normalnom ko&scaron;tanom gustinom u kontrolnoj grupi. Eksperimentalna grupa bolesnica imala je lo&scaron;iju funkciju &scaron;ake, odnosno lo&scaron;iji skor primenom validiranih upitnika ( p &lt;0,001). ZAKLJUČAK: Pacijentkinje sa izraženom osteoartrozom &scaron;aka imaju smanjenu funkciju &scaron;ake, če&scaron;ći metabolički sindrom u odnosu na kontrolnu grupu, ali ne i značajno nižu ko&scaron;tanu gustinu.</p> / <p>INTRODUCTION: Arthritis of the hand is one of the most common musculoskeletal disorders. It manifests as pain, sometimes accompanied by swelling and deformities, which may lead to the loss of hand function. However, there is no consensus on the relationship between osteoarthritis (OA) and osteoporosis (OP) as the two most common skeletal disorders. AIMS: The study aim was to determine the risk factors related to the development of OA in the hand, as well as compare the bone density in patients with hand OA (HOA) with that measured in the control group and establish the significance of metabolic syndrome in the HOA group. MATERIAL AND METHODS: The study was conducted over a 12-month period and included a sample comprising of the experimental (patients affected by HOA) and the control (individuals with no evidence of HOA) group. HOA was diagnosed based on the reported pain, clinical evidence of hand deformities in postmenopausal women aged 60&minus;70, and radiological evidence of physiological changes (Grade II to IV, based on the Kellgren-Lowrence scale). The risk factors for the development of HOA were analyzed, along with the link between HOA and hand grip strength, bone mineral density and metabolic syndrome. Analyses also included had function, as determined by three validated questionnaires: Michigan Hand Outcomes Questionnaire (MHQ), Duruoz Hand Index (DHI), and Health Assessment Questionnaire (PROMIS HAQ). Statistical analyses were performed using the SPSS version 25 computer software. RESULTS: The average age of the sample was 65.89&plusmn;3.67 years. There were statically significant differences between the experimental and the control group with respect to the family history of structural changes in the hand joints, perceived hand pain at rest and when palpated, reluctance to utilize fingers, hand grip strength, and metabolic syndrome (p &lt; 0.001). Family history of structural changes to the hand joints and metabolic syndrome emerged as the strongest predictors of the osteoarthritis of the hand development (p &lt; 0.001). A greater number of the control group members had normal bone mineral density, while the patients assigned to the experimental group had inferior hand function, as determined by the score on the aforementioned validated questionnaires (p &lt; 0.001). CONCLUSION: Postmenopausal women with pronounced osteoarthritis of the hand have reduced hand function, and are more likely to suffer from a metabolic syndrome relative to the control group, while the differences in bone mineral density are not statistically significant.</p>
