title: Effect of body posture and time on grip strength in patients with cervical spondylosis.
abstract: Ninety-eight patients with cervical spondylosis were tested for grip strength in different spinal postures (standing and sitting), but with standard upper arm position. Unilateral symptoms of cervical spondylosis significantly affected grip strength in that arm whether or not it was the dominant upper limb, in contrast to normals. Grip strength is stronger in the standing position than in a sitting posture with the neck flexed (P < 0.01; at 10 min), and this effect is increased by duration in the posture.
