- Background:Impaired grip ability in RA is due to reduced strength in the flexor muscles as well as by dysfunctional extensor muscles leading to inability to open the hand. Furthermore the extensor muscles are important for stabilization during flexion force production and active for developing a controlled grip force. There is today scientific evidence showing that various forms of hand exercise are beneficial for improving hand function and strength in RA patients (Ronningen and Kjeken 2008; Brorsson, Hilliges et al. 2009). However, comparatively little research has evaluated and specific designed hand exercise program for the extensor muscles controlling the hand and fingers (Weiss, Moore et al. 2004; O'Brien, Jones et al. 2006).Objectives:The objectives for this study were to evaluate the effect of an exercise program on hand strength, hand function and perceived function of daily life activities among RA patients and to explore the possibility to improve the balance between the extensor and flexor muscle forces in the hand.Methods:The study group comprised of 20 patients with RA (median disease duration 20 years) that performed a hand exercise program for twelve weeks. The finger extension force was measured with a newly developed device (EX-it), finger flexion force was measured with the Grippit. Hand function was evaluated with the Grip Ability Test (GAT) and self reported questionnaire Disability Arm Shoulder and Hand (DASH).Results:Hand strength (both extension and flexion force) and hand function improved significantly after twelve weeks. The RA group showed improvement in the results of the DASH questionnaire (p < 0.05), but on individual level, the result was partly significant. The relation between extension and flexion force in the hand was not correlated, however, after the exercise there was a strong association between flexion and extension force (p < 0.001). The result on individual level is related to age and duration time.Conclusion:Twelve weeks of hand exercise significantly improved hand strength, hand function and perceived function for RA patients. Furthermore, exercise improved the relation between the finger extension and flexion force. Hand exercise is thus an effective intervention for RA patients, providing better strength and function.References:Brorsson, S., M. Hilliges, et al. (2009).

- OBJECTIVE: Balance between flexor and extensor muscle activity is essential for optimal function. The purpose of this pilot study was to compare the relationship between maximum finger flexion force and maximum finger extension force in women with rheumatoid arthritis and healthy women.METHODS: Twenty healthy women (median age 61 years) and 20 women with rheumatoid arthritis (median age 59.5 years, median disease duration 16.5 years) were included in the study. Finger extension force was measured with an electronic device, EX-it, and finger flexion force using Grippit. The Grip Ability Test and the score from the patient-reported outcome Disability Arm Shoulder and Hand were used to evaluate activity limitations.RESULTS: Patients with rheumatoid arthritis showed significantly decreased hand function compared with healthy controls. A correlation was found between extension force and flexion force in the healthy group (r = 0.65, p = 0.002),but not in the rheumatoid arthritis group (r = 0.25, p = 0.289).CONCLUSION: Impaired hand function appears to influence the relationship between maximum finger flexion and extension force. This study showed a difference in the relationship between maximum finger flexion and extension force in healthy controls and those with rheumatoid arthritis. © 2012 Foundation of Rehabilitation Information.
