OBJECTIVE: This study measured functional capacity and subjective @entity158 in @entity1 with @entity4048 before and after manipulation of the cervical spine. DESIGN: Outcomes study on 16 @entity1 with @entity4048 . BACKGROUND: Muscle inhibition, i.e., the inability to fully activate a muscle, has been observed following joint pathologies and in low back @entity158 conditions. Although @entity4048 has been associated with changes in muscle recruitment and coordination in the shoulder and arms, the possibility of muscle inhibition has not been explored. METHODS: Biceps activation during a maximal @entity2472 was assessed using the interpolated twitch technique and electromyography. Cervical @entity11535 and pressure @entity158 thresholds were measured using a goniometer and an algometer. Manipulation of the cervical spine was applied at the level of @entity9509 , and functional assessments were repeated. RESULTS: @entity1 showed significant inhibition in their biceps muscles. Cervical @entity11535 was restricted laterally, and increased pressure @entity158 sensitivity was evident. After cervical spine manipulation, a significant reduction in biceps inhibition and an increase in biceps force occurred. Cervical @entity11535 and pressure @entity158 thresholds increased significantly. CONCLUSIONS: Significant dysfunction in biceps activation was evident in @entity1 with @entity4048 , indicating that this muscle group cannot be used to the full extent. Spinal manipulation decreased muscle inhibition and increased elbow flexor strength at least in the short term. RELEVANCE: Muscle inhibition in the biceps has not been previously documented in @entity1 with @entity4048 . Further research is needed to establish whether muscle inhibition is related to clinical symptoms and functional outcome. Spinal manipulation improved muscle function, cervical @entity11535 and @entity158 sensitivity, and might therefore be beneficial for treating @entity1 with @entity4048 .
