In the tandem walk, participants walk tandem (heel-to-toe) over a line visible on the walkway (1 recording).
Schumer and Clinton struggled with that question, walking in tandem for many weeks after their blowup off the Senate floor, then subtly drifting just a bit apart.
Artur Zmijewski's riveting film of two naked men — one has had his leg amputated — walking in tandem up and down stairs and in the woods, ends on a funny-sad note: they lie on a bare wooden floor and perform a silly dance routine to the accompaniment of their own whistling.
There are three major components of the SPPB: standing balance (standing with feet together in three positions of increasing difficulty: side-by-side, semi-tandem, and tandem), walking speed (usual speed on a four meter course), and ability to rise from a chair (time to rise five times from a chair with arms folded across the chest).
With cameraman Thomas Mauch, Herzog used to walk in tandem, his hands around Mauch's waist, or hooked into his belt, so that the camera, its operator and the director could fuse.
No significant changes over time or between groups were observed in the other physical performance measures (six-minute walk distance, tandem walk, single-leg stance duration, muscle strength, power, and endurance, or habitual gait speed (CV = 3.16%)) (Table 3).
Subjects also performed two widely used clinical tests; tandem walking [ 30] and repeated chair rise [ 31, 32].
During the tandem walking test, subjects were instructed to walk so that at each step the toes of the back foot touched the heel of the front foot.
Functional mobility will be assessed with the SPPB which includes tests of side-by-side, semi-tandem, and tandem standing, walking speed over 3 metres, and time to complete five chair rises.
The Short Physical Performance Battery (SPPB) will be used to assess lower extremity function based on the following tests: static balance (side-by-side, semi-tandem, and tandem stance), walking speed over 4 m (at normal pace), and the five times chair stand test [ 28].
The exercises included: strengthening exercise, emphasizing hip abductors and extensors; closed kinetic chain quadriceps exercise; marching; stepping over a bench; standing up from a chair with arms folded; and tandem walk (walking heel-to-toe in a straight line).
