Arthritis occurs when the cartilage which protects the joint surface wears out. The most common arthritis of the thumb is Thumb Carpometacarpal (CMC) Joint Arthritis which is where the base of the thumb and your wrist meet. This typically occurs either from degenerative changes, but more commonly through wear and tear. As the cartilage breaks down, the end of your bones can rub together causing pain and inflammation, which can make it difficult to use your thumb for everyday activities. 

Common signs or symptoms of Thumb CMC arthritis include joint pain (typically increased with use), joint inflammation, stiffness, decreased strength (especially with pinching or grasping objects), decreased ROM. CMC arthritis is more common in women than in men, ages 45+, post menopause, and in those with a family history. Previous trauma or injury to the thumb and also lead to thumb arthritis. Common risk factors include activities with repetitive motion and/or compressive forces to the base of the thumb. 

Common treatment approaches for therapy: 

– Splinting to promote stability of the base of the thumb 

– There are many types of orthoses which can be appropriate- it is best to seek further care to advise regarding what is appropriate for you. 

– ROM exercises to maintain ROM 

– Stretching of soft tissue structures of the hand 

– Manual techniques for pain reduction including but not limited to joint mobilization, instrument assisted soft tissue mobilization (scraping), cupping, and/or dry needling – Patient education regarding joint protections strategies to reduce pain and preserve the joint. 

Some simple ROM exercises to maximize motion and function of your hand include: – Each exercise should be completed slowly, holding the end range for 5-10 seconds. – Completed 10-20 repetitions of each exercise for 1-2 sets. 

1. Bend your thumb across your palm and then fully straighten your thumb.
