This lesson teaches a provider-built route with one firm uneven mat and one low obstacle: preview the route, choose the aid and lead strategy, approach at controlled speed, shorten steps, place the whole foot on known surfaces, clear the obstacle without rushing and pause after each transition. The provider controls surface, obstacle, guarding, repetitions and progression. Target outcome: The learner completes a supervised declared route with the same aid while obstacle contacts, stumbles, pauses, assistance, time and symptoms are recorded. ### Authority and setup conditions - Walk or visually inspect the route with the provider and identify every surface change and rest point. - Check that mats and obstacles cannot slide and that an escape route remains clear. - Report falls, dizziness, pain, sensory loss, vision change, fatigue and any new aid or footwear. - Walk beside the secured route and identify every surface change, obstacle and exit. Ask the learner to point out the next transition while standing still before attempting it with the planned aid and guard. - Walk the route beside the obstacles, rehearse the aid and lead plan and practise looking ahead before attempting the secured transitions. ### Required or supplied materials - Provider-secured route with level lead-in/out, one uneven mat and one low obstacle - Usual mobility aid and footwear - Gait belt or guarding equipment when indicated - High-contrast edge marks and route video/score sheet - A terrain-route record with surface and obstacle dimensions, aid, lead strategy, guarding, contacts, pauses, stumbles, assistance, time, symptoms and invalid trials. ## 1. Preview the route Stop on level ground and scan from near to far, naming the mat, obstacle, exit and any support point. Why: Planning reduces late surprise without removing the adaptation task. Success check: The learner points to each transition and exit. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The learner points to each transition and exit.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 2. Set aid and lead plan Use the provider-agreed aid placement and lead foot for this route; keep the aid inside the support area. Why: Aid and lead strategy affect stability. Success check: The learner demonstrates the first transition on level ground. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The learner demonstrates the first transition on level ground.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 3. Approach under control Walk at a pace that allows a stop before the transition and shorten the final steps rather than lunging. Why: A controllable approach preserves time to place the foot. Success check: The learner can pause before the mat without a recovery step. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “The learner can pause before the mat without a recovery step.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 4. Place the whole foot On the known uneven mat, place enough of the foot to support weight and keep knee/trunk aligned; use the aid before transferring weight as taught. Why: Edge or partial contacts can slip or roll. Success check: Foot and aid land inside the marked safe area. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Foot and aid land inside the marked safe area.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 5. Clear the low obstacle Look ahead to the landing spot, lift the lead foot over without circling, then bring the trailing foot through before accelerating. Why: A rushed trailing foot commonly contacts the obstacle. Success check: Neither foot touches and landing remains inside the lane. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Neither foot touches and landing remains inside the lane.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 6. Stabilise after each change Take one or two settling steps and pause if needed before the next feature; do not link features faster than control allows. Why: Terrain adaptation includes recovery after transition. Success check: Balance is stable before the next feature. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Balance is stable before the next feature.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## 7. Score errors and assistance Record obstacle contacts, foot-placement errors, pauses, rail/helper contact, time and symptoms. Keep the aid visible in the result. Why: Completion alone hides how the route was achieved. Success check: Every trial has error and assistance fields. Accessible alternative: Ask the qualified provider to adapt positioning, cue modality, pace, interface or rest while preserving this step’s declared check: “Every trial has error and assistance fields.” If an adaptation changes the measured task or configuration, record it as a different configuration rather than an equivalent attempt. Alternative relationship: Conditional equivalence requires target and configuration check Learner notes: ________________________________________________________________________________ Completed: [ ] ## Reflection What changed? ________________________________________________________________________________ What remains difficult? ________________________________________________________________________________ What will I repeat, adapt, ask for help with, or stop? ________________________________________________________________________________ --- Completion of this worksheet demonstrates tutorial participation only.
