Off-the-shelf activity-promoting video games (AVGs) are proposed as a
tool for promoting regular physical activity among individuals poststroke.
OBJECTIVE: To characterize the energy expenditure (EE), exercise intensity, and
energy metabolism of individuals poststroke, while playing AVGs in different
positions, from different consoles, and to compare the performance with
comfortable walking and with able-bodied individuals. METHODS: Eleven poststroke
and 8 able-bodied participants played in standing Wii-Boxing Xbox-Boxing, Wii-Run
and Penguin, and also Wii-Boxing in sitting. EE (expressed as metabolic
equivalents [METs]); exercise intensity (expressed as %predicted maximal heart
rate [HR]), rate of perceived exertion (RPE), and respiratory exchange ratio
(RER) were used to characterize the games. RESULTS: Participants' poststroke EE
ranged from 1.81 +/- 0.74 to 3.46 +/- 1.3 METs and was lower compared with
able-bodied participants for Xbox-Boxing (P = .001), Wii-Boxing in standing (P =
.01), Run (P < .001), and Penguin (P = .001). Participants' poststroke exercise
intensity ranged from 49.8 +/- 9.3 to 64.7 +/- 9.3 %predicted maximal HR and was
lower compared with able-bodied participants for Xbox-Boxing (P = .007) and Run
(P = .005). For participants poststroke, EE of walking at a comfortable did not
differ from boxing games in standing or Run. For able-bodied participants only,
the EE for Xbox-Boxing was higher than Wii-Boxing (6.5 +/- 2.6 vs 4.4 +/- 1.1, P
= .02). EE was higher in standing versus sitting for poststroke (P = .04) and
able-bodied (P = .03) participants. There were no significant group differences
for RPEs. RER of playing in sitting approached anaerobic metabolism. CONCLUSIONS:
Playing upper extremity (ie, Boxing) or mobility (ie, Run) AVGs in standing
resulted in moderate EE and intensity for participants poststroke. EE was lower
for poststroke than for able-bodied participants.
