Abstract
Background
The unique anatomy of the human hand makes it possible to carefully manipulate tools,
powerfully grasp objects, and even throw items with precision. These apparent contradictory
functions of the hand, high mobility for manual dexterity vs high stability during
forceful grasping, imply that daily activities impose a high strain on a relatively
instable joint. This makes the hand susceptible to joint disorders such as osteoarthritis.
Both systemic (eg, genetics, hormones) and mechanical factors (eg, joint loading)
are important in the development of osteoarthritis, but the precise pathomechanism
remains largely unknown. This paper focuses on the biomechanical factors in the disease
process and how hand therapists can use this knowledge to improve treatment and research.
Conclusion
Multiple factors are involved in the onset and development of osteoarthritis in the
hand. Comprehension of the biomechanics helps clinicians establish best practices
for orthotics intervention, exercise, and joint protection programs even in de absence
of clear evidence-based guidelines. The effect and reach of hand therapy for OA patients
can be expanded substantially when intervention parameters are optimized and barriers
to early referrals, access reimbursement, and adherence are addressed. Close and early
collaboration between hand therapists and primary care, women's health, rheumatology,
and hand surgery providers upon diagnosis, and with hand surgeons pre and postoperatively,
combined with advances in the supporting science and strategies to enhance adherence,
appear to be a promising way forward.
