In Table 1 of this article, the term "VC" in Sikka et al.’s outcome measures should be revised to "SVC (slow vital capacity)." The Table 1 should be corrected as follows:
Table 1.
Features of the trials included
| Reference | Sex (M/F) | Sample size (T/C) | Stage of injury | Level of injury | Training protocol | Control | Intervention duration (wk) | Outcome measures |
|---|---|---|---|---|---|---|---|---|
| Liaw et al., 2000 [39] | 16/4 | 10/10 | Acute, sub-acute | C4–C7 | Training commenced with the lowest level of inspiratory resistance (blue, 7 mm). Duration: 15–20 minutes, twice a day, 7 days/wk | Usual care | 6 | MIP, MEP, VC, FVC, FEV1 |
| Mueller et al., 2013 [38] | 12/4 | 8/8 | Sub-acute, chronic | C5–C8 | 80% MIP, 90 repetitions for 10 minutes session, 4 days/wk | Placebo | 8 | MIP, MEP, VC, FEV1, QoL (SF-12) |
| West et al., 2014 [13] | 9/1 | 5/5 | Chronic | C5–C7 | 60% MIP, 30 repetitions each session, twice a day, 5 days/wk | Placebo | 6 | MIP, MEP, FVC, FEV1 |
| Boswell-Ruys et al., 2020 [10] | 57/3 | 29/31 | Acute, sub-acute, chronic | C4–C7 | 80% MIP, 3–5 sets of 12 breaths with a rest period of 2 minutes, twice daily, for 5 days a week | Sham intervention | 6 | MIP, MEP, VC, FVC, FEV1, QoL (SF-36) |
| Sikka et al., 2021 [37] | 72/24 | 48/48 | Acute | C4–C7 | 70% MIP, 6 sets of 12 repetitions each session, twice a day, 5 days/wk | Conventional intervention | 4 | MIP, MEP, SVC, FVC, FEV1 |
M/F, male/female; T/C, treatment/control; MIP, maximal inspiratory pressure; MEP, maximal expiratory pressure; VC, vital capacity; FVC, forced vital capacity; FEV1, forced expiratory volume in 1 second; QoL, quality of life; SF-12, Short Form 12 Health Survey; SF-36, 36-Item Short Form Survey; SVC, slow vital capacity.
