Effect of physical therapy interventions in individuals with primary thumb carpometacarpal osteoarthritis: a systematic review and meta-analysis.

Purpose: This systematic review and meta-analysis aimed to investigate the effect of physiotherapeutic interventions in individuals with thumb primary CMC OA on the outcomes of pain, hand function, grip or pinch strength.

Methods: RCTs that used some type of physiotherapeutic intervention compared to a passive or active control group were included. The quality of the evidence was assessed using the GRADE approach and, for the calculation of the meta-analysis, the standardized difference of means (SMD) was used.

Effect of first dorsal interosseous strengthening on clinical outcomes in patients with thumb osteoarthritis: a study protocol for a randomized controlled clinical trial.

Background: Thumb carpometacarpal osteoarthritis (CMC OA) is characterized by chronic progressive degeneration of the joint cartilage, with high prevalence. Patients present with pain at the base of the thumb, morning stiffness, and muscle weakness, symptoms that affect hand function and therefore interfere in activities and social participation. Movements that involve grip or lateral pinch are the most affected and directly impact independence, self-care, and leisure activities.

Initial stages of hand osteoarthritis do not affect the extrinsic muscles of the hand: a cross-sectional study.

The objective of this study was to verify whether women in the initial stages of hand osteoarthritis (HOA) already have impaired grip strength and flexor and extensor torque of the wrist compared to healthy women. It also aimed to correlate these variables with pain, stiffness, and function of the hand. Twenty-six women were divided into a control group [CG, n = 13; 56 (51-61) years old] and a hand osteoarthritis group [HOAG, n = 13; 58 (53-63) years old].

Impairment of electrical activation of wrist flexor and extensor muscles during gripping and functional activities in the early stage of hand osteoarthritis: A cross-sectional study.

Study Design: This is a cross-sectional study.

Introduction: The wrist extensor muscles have a fundamental role in the stabilization of the wrist while performing manual activities. However, it is unknown if the clinical signs of hand osteoarthritis (HOA) cause impairment in the activation of these muscles PURPOSE OF THE STUDY: The purpose of this study was to investigate whether early-stage HOA affects the magnitude of activation and coactivation between the wrist extensor and flexor muscles METHODS: Thirty-two subjects were divided into two groups: control group (n = 16; 55 ± 7.
