The effect of rigid tape on wrist postures during tree planting
Bibliographic record
Abstract
Taping has been suggested to reduce the incidence of tendinopathy in tree planters. However, the ability of taping to reduce wrist postures during planting has not yet been formally evaluated. The primary aim was to test the effect of rigid taping on wrist postures during tree planting tasks. Eleven tree planters planted up to 50 trees in three conditions: no-tape (NT), tape-on-the-dorsum-of-the-hand (T1) and tape-on-the-thumb (T2) in a randomised cross-over, within-participant, repeat-measures design. Electrogoniometers (EG) recorded continuous wrist postures. Digital video recordings were used to segment EG traces of each planting cycle (one planted tree) into 4 kinematically distinct Phases. The tree and shovel wrist were analysed separately. Tree-wrist peak ulnar deviation and frequency of shovel-wrist awkward frontal plane postures were significantly reduced in the T2 condition. Taping may be effective at reducing non-neutral postures and should be researched further to determine its effectiveness in reducing tree planting injuries. Practitioner summary: The effect of rigid taping on wrist postures during tree planting has not yet been formally evaluated. A randomised cross-over, within-participant, repeat measures design was used to evaluate the effect of rigid taping on wrist postures during planting. Thumb rigid taping appeared to reduce wrist range of motion during planting. KEY POINTSTaping of the thumb reduced peak ulnar deviation of the tree wrist and frequency of awkward frontal plane postures of the shovel wrist.While taping of the dorsum of the hand appeared to be more restrictive, it did not significantly reduce wrist movement; this is likely because only its effect on sagittal plane posture was assessed which had a higher variance.Upon application, tape appeared to restrict voluntary movement patterns, decreased voluntary grip force exertion and physically restrain wrist movement.Overall, rigid tape was found to be an acceptable intervention for the tree planting occupation, with financial costs and perceived effort identified as the primary barriers to acceptability.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
