Activities of daily living and therapeutic activities

In short

Activities of daily living (ADL) are the self-maintenance occupations a person must perform to live — eating, bathing, toileting, dressing, grooming, functional mobility — plus the instrumental tasks (IADL) of managing a home, money, medicines and travel. Occupational therapy restores them either by remediation (improving the impaired component), compensation (new technique, adapted method or device) or modification of the task and environment, and measures the result on standard scales such as the Barthel Index, Katz Index, Lawton IADL Scale and FIM. Therapeutic activities are the graded, purposeful and occupation-based tasks used as the treatment medium itself — the defining tool of the profession. This topic is examined in every BOT university paper on OT process, in RCI/NCAHP-pattern entrance and licensing questions, and in interviews at AIIMS, CMC Vellore, NIMHANS, Safdarjung, Sion/KEM Mumbai, Composite Regional Centres, NGOs and corporate rehabilitation units, where ADL scores decide admission, discharge, disability certification and insurance claims.

Explained

Definitions and classification of daily occupations

• ADL / BADL / PADL (basic or personal ADL): body-centred, survival-level tasks learnt in early childhood. OTPF-4 lists bathing and showering, toileting and toilet hygiene, dressing, eating, feeding, functional mobility, personal device care, personal hygiene and grooming, and sexual activity.
• Eating vs feeding: *eating* is keeping and swallowing food already in the mouth; *feeding* is setting up and bringing food from plate to mouth. Examiners test this distinction.
• IADL (instrumental ADL): interaction with the environment — meal preparation and clean-up, home establishment and management, shopping, financial management, health management, communication management, driving and community mobility, care of others and pets, child rearing, religious and spiritual expression, safety and emergency maintenance, wayfinding.
• AADL (advanced ADL): discretionary roles — work, study, worship, sport, social participation; the highest rung and often the patient's real goal.
• Hierarchy of recovery: bed mobility → transfers → feeding → grooming → upper-body dressing → lower-body dressing → toileting → bathing → IADL. Train in this order; bathing and lower-body dressing are the last BADL regained after stroke.
• ICF mapping: impairment = body function/structure, ADL limitation = *activity*, inability to fulfil roles = *participation restriction*. ADL training works at the activity level; home and community change works at participation (covered under home modification).

Measuring ADL performance

• Barthel Index (Mahoney and Barthel, 1965): 10 items, scored 0/5/10/15, total 0–100 in steps of 5. Bands commonly quoted: 0–20 total dependence, 21–60 severe, 61–90 moderate, 91–99 slight, 100 independent (cut-offs vary between texts — state the version you use).
• Modified Barthel Index (Shah, 1989): same 10 items with 5 levels each, better sensitivity to small change; a 20-point version also exists, so always report the maximum.
• Katz Index of Independence in ADL (1963): 6 items — bathing, dressing, toileting, transferring, continence, feeding — scored 0 or 1, total 0–6; quick screening in geriatrics.
• Lawton and Brody IADL Scale (1969): 8 items, total 0–8 (historically 0–5 for men, omitting cooking, housekeeping and laundry — a cultural bias students should name).
• FIM (Functional Independence Measure): 18 items (13 motor + 5 cognitive), each 1–7, total 18–126. Levels: 7 complete independence, 6 modified independence (device/extra time/safety concern), 5 supervision or set-up, 4 minimal contact assistance (patient does ≥75%), 3 moderate (50–74%), 2 maximal (25–49%), 1 total assistance (<25%).
• Others: Klein-Bell ADL Scale (item broken into very small steps, good for documenting minute gains), PULSES Profile, AMPS (observed motor and process skills), WeeFIM and PEDI in paediatrics.
• Rule of recording: score what the patient actually does, not what they can do on request, and note whether the source is observation, self-report or carer report. Observation is the reference standard.

Principles of ADL training

1. Set client-centred, measurable goals ("will don a shirt unassisted, seated, in under 5 minutes, by day 10") with the patient and family.
2. Choose the approach: remedial (strengthen, increase ROM, retrain coordination) early and when recovery is expected; compensatory when deficits are permanent or time is short; most real plans blend both.
3. Teach in the real context and at the real time — dressing at the bedside in the morning, cooking in a kitchen, not a simulated table-top drill.
4. Backward and forward chaining: forward chaining teaches step 1 first; backward chaining has the therapist do all steps and the patient complete the last one, so every attempt ends in success — useful in dementia and brain injury.
5. Grade the assistance down the FIM ladder: hand-over-hand → physical prompt → verbal cue → gesture → supervision → independent.
6. Practice schedule: blocked, massed practice for early acquisition; random and distributed practice for retention and transfer; use errorless learning in memory impairment.
7. Train the carer and write the method down in the family's language; discharge is unsafe without a carer demonstration.
8. Safety first: falls, burns, sharps, swallowing risk, pressure care, cardiac tolerance, and precautions (total hip, post-CABG sternal, post-flexor-tendon) are checked before any task.

Therapeutic activity: selection, grading and adaptation

• Continuum of intervention (OTPF-4): *preparatory methods and tasks* (positioning, passive ROM, modalities, orthoses, rote exercise) → *purposeful activity* (a contrived but goal-directed task, e.g. pegboard, putty, stacking cones) → *occupation-based intervention* (the client's actual occupation in its real context). Occupation-based ranks highest because meaning drives motivation, attention and carry-over.
• Properties that make an activity therapeutic: it has a purpose and meaning for the client, demands the target component, can be graded, is safe, time- and cost-feasible, is culturally acceptable, and is analysable into steps.
• Grading parameters — change one variable at a time: resistance/weight, repetitions, duration, speed, ROM required, height and plane of work, size/weight/texture of object, number of steps, cognitive complexity, position (supine → sitting → standing), degree of cueing, noise and distraction.
• Adaptation (compensation): change the method (one-handed technique), the object (built-up handle, long-handled reacher), the position, or the environment; devices themselves are detailed under assistive technology.
• Therapeutic use of self: the therapist's rapport, instruction style and feedback are themselves a treatment tool.
• Indian practice note: crafts and activities used in Indian OT departments — chapati rolling, wet grinding, floor-sitting cross-legged tasks, squat toileting, rangoli, weaving, pottery, coir and cane work, tailoring — are valid therapeutic media because they are the real occupations of the clientele. Squatting tolerance and eating with the right hand must be trained explicitly; Western ADL checklists omit both.

Condition-specific ADL methods (high-yield)

• Hemiplegia dressing: dress the affected side first, undress the unaffected side first; sit supported; front-opening loose clothing; cross the affected leg over for socks; one-handed shoe tying or elastic laces.
• One-handed techniques: stabilise the plate with a non-slip mat, rocker knife for cutting, suction nail brush, wall-mounted soap, toothpaste tube squeezed against the counter.
• Spinal cord injury, by level: C1–C4 dependent in BADL (mouthstick, environmental control, sip-and-puff); C5 feeding, grooming with mobile arm support and wrist splint; C6 is the key level — tenodesis grasp gives independent feeding, grooming, upper-body dressing, often self-catheterisation and sliding-board transfers; C7–C8 independent transfers and most BADL; T1 and below full BADL independence, wheelchair-based IADL.
• Rheumatoid arthritis — joint protection: respect pain; balance rest and activity; avoid positions of deformity (no tight pinch, no ulnar drift stress); use the largest and strongest joints; distribute load over several joints; avoid prolonged static grip; use levers and lightweight utensils; stop before fatigue.
• Energy conservation — the four P's: Plan, Prioritise, Pace, Position; plus sit to work, slide rather than lift, keep items within arm's reach, use both hands symmetrically, eliminate unnecessary steps (work simplification), alternate heavy and light tasks, rest before exhaustion. Core in COPD, cardiac disease, cancer fatigue, multiple sclerosis, post-polio and long-term fatigue states.
• Cardiac and pulmonary rehabilitation: progress ADL by MET cost — grooming while seated ~1.5–2 METs, sponge bath ~2, showering/dressing ~3.5, stair climbing 4–5, carrying 10 kg upstairs 6+. Keep activity within the prescribed MET ceiling, teach pursed-lip breathing and exhale on effort (no Valsalva).
• Low vision and blindness: tactile and high-contrast marking, fixed-place organisation, trailing, talking devices, clock-face plate description.
• Dementia: simplify choices, lay out clothing in order, verbal/visual cues, keep the routine and the environment unchanged, use procedural memory.
• Total hip replacement precautions (posterior approach): no flexion beyond 90°, no adduction past midline, no internal rotation — hence raised toilet seat, long-handled sponge and sock aid, and no low Indian-style toilet or floor sitting until cleared.
• Paediatrics: train ADL against developmental norms — self-feeding with fingers ~12–15 months, spoon ~18 months, removing clothes ~2 years, dressing with supervision ~3–4 years, independent toileting ~3–4 years, buttons ~4 years, laces ~5–6 years.

Indian regulation, schemes and documentation

• Rights of Persons with Disabilities Act, 2016 (with the RPwD Rules, 2017): 21 specified disabilities, benchmark disability 40%, reasonable accommodation, accessibility obligations; the Government's assessment guidelines notified in 2018 use ADL-type functional criteria for several conditions, so an OT's ADL record feeds directly into certification on the UDID portal.
• Professional regulation: occupational therapy is a recognised profession under the National Commission for Allied and Healthcare Professions Act, 2021, with central and state councils and curriculum/registration powers; rehabilitation professionals have historically also been registered under the Rehabilitation Council of India Act, 1992. The transition between the two registers is still being implemented, so verify the current requirement with the council before quoting it. AIOTA is the national professional body and WFOT member.
• Schemes an OT works with: ADIP (assistive devices, Ministry of Social Justice and Empowerment), DDRS, NPRPD, Composite Regional Centres and the national institutes (NIEPMD Chennai, NILD Kolkata, PDUNIPPD New Delhi, NIEPID Secunderabad), Sugamya Bharat Abhiyan for accessibility, and rehabilitation packages under Ayushman Bharat PM-JAY — package lists are revised periodically, so check the current HBP master.
• Documentation: SOAP notes; goals written as measurable, time-bound statements; ADL score on admission, at review and at discharge; carer-training note; home programme in the local language. Insurers and medico-legal/disability boards read these scores, so an unsigned or unscored ADL entry is a professional lapse.

Key points

• ADL - self-maintenance tasks (bathing, dressing, toileting, eating, feeding, grooming, functional mobility, personal device care, sexual activity).
• IADL - environment-directed tasks: cooking, shopping, money, medicines, transport, home management, child care.
• Eating vs feeding - eating is managing food in the mouth; feeding is bringing it to the mouth.
• Barthel Index - 10 items, 0–100 in steps of 5; Modified (Shah) version has 5 levels per item.
• Katz Index - 6 BADL items, score 0–6; Lawton IADL - 8 items, score 0–8.
• FIM - 18 items × 1–7 = 18–126; level 4 means the patient contributes ≥75% of the effort.
• Score performance, not capacity - record what the patient actually did, and name the information source.
• Remediation vs compensation - fix the impairment vs change the method, tool or environment; most plans use both.
• Backward chaining - therapist does all steps, patient completes the last, so each trial ends in success.
• Dressing rule in hemiplegia - affected limb in first, unaffected limb out first.
• C6 tetraplegia - tenodesis grasp is the functional watershed for independent feeding and grooming.
• Joint protection - respect pain, use the largest joints, avoid sustained grip and deformity-producing positions.
• Four P's of energy conservation - Plan, Prioritise, Pace, Position.
• MET - 1 MET = 3.5 ml O₂/kg/min at rest; ADLs are prescribed within the cardiac MET ceiling.
• Activity continuum - preparatory → purposeful → occupation-based; occupation-based gives the best motivation and carry-over.
• Grading - alter resistance, duration, ROM, height, complexity, position or cueing, one variable at a time.
• Indian ADL specifics - squat toilet, floor sitting, eating with the right hand, chapati making must be assessed and trained, not assumed.
• RPwD Act 2016 and NCAHP Act 2021 - the legal frame for benchmark disability (40%) and for OT registration respectively.

Formulas and examples

Example 1 — Barthel Index after a stroke. A 62-year-old with left hemiplegia: feeding 5 (needs help cutting), bathing 0, grooming 5, dressing 5 (half, with help), bowels 10, bladder 10, toilet use 5, transfers 10 (minor help), mobility 10 (walks 50 m with the help of one person), stairs 0. Total = 5+0+5+5+10+10+5+10+10+0 = 60/100. On the common banding this sits at the top of the *severe dependence* band (21–60) and one 5-point gain moves him into *moderate* — illustrating why the Modified Barthel, with finer steps, is preferred for tracking progress.

Example 2 — FIM gain, efficiency and relative gain. Admission FIM 54, discharge FIM 96, length of stay 28 days.

• Gain = 96 − 54 = 42 points
• Efficiency = 42 ÷ 28 = 1.5 points/day
• MRFS = 42 ÷ (126 − 54) × 100 = 42/72 × 100 = 58.3% of the available improvement achieved.

Example 3 — MET-based ADL prescription in cardiac rehabilitation. Patient 70 kg, exercise test ceiling 4 METs; standing shower with towelling and dressing ≈ 3.5 METs.

• Energy cost = 3.5 × 3.5 × 70 ÷ 200 = 857.5 ÷ 200 = 4.29 kcal/min; over 15 min = 64 kcal.
• That is 3.5/4 = 87.5% of his ceiling — too close for daily use. Switch to a seated shower with a shower chair and long-handled sponge (≈2 METs): 2 × 3.5 × 70 ÷ 200 = 2.45 kcal/min, i.e. 50% of ceiling, and insert a rest before dressing.

Example 4 — Katz and Lawton in a geriatric home visit. An 80-year-old widow: bathing needs help (0), dressing independent (1), toileting independent (1), transferring independent (1), continent (1), feeds self (1) → Katz 5/6. IADL: telephone 1, shopping 0, food preparation 0, housekeeping 0, laundry 0, transport 0, medication 1, finances 1 → Lawton 3/8. Reading: BADL nearly intact but IADL failing — the classic early-dementia or deconditioning pattern; priority is meal preparation, shopping and community mobility, not BADL drill.

Example 5 — converting assistance to a FIM level. In sit-to-stand the therapist lifts about 40% of the work, the patient 60%: 60% lies in 50–74% → FIM 3, moderate assistance. After two weeks the patient does 85% → ≥75% → FIM 4, minimal assistance; when only steadying and set-up are needed with no hands on → FIM 5, supervision.

Where it is used

• Tertiary hospital rehabilitation units — AIIMS, CMC Vellore, NIMHANS, Safdarjung, Seth GS/KEM and LTMG Sion Mumbai: stroke, TBI, spinal injury and burns wards where FIM or Barthel drives the discharge decision.
• Geriatric and palliative care, old-age homes and home-care start-ups — Katz/Lawton-led ADL retraining, falls prevention, carer training, energy conservation.
• Composite Regional Centres, national institutes and NGOs (NIEPMD, NILD, PDUNIPPD, Spastics Society/ADAPT, AMAR Seva Sangam) — paediatric self-care training and ADIP device fitting under DEPwD schemes.
• Disability certification and medico-legal work — ADL findings support UDID assessment under the RPwD Act, 2016, and personal-injury and insurance claims.
• Industrial, corporate and insurance rehabilitation — return-to-work programmes, work simplification and ergonomic advice for RSI, back pain and post-cardiac-event employees; ESIC and large plant medical centres.
• Job roles — occupational therapist (Group B/entry grade in government hospitals), rehabilitation officer, early-intervention therapist, paediatric OT in schools, hand-therapy and burns units, academic posts in BOT/MOT colleges.

Interview questions

• Q: Differentiate BADL from IADL with two examples each. A: BADL are body-centred survival tasks — bathing, dressing; IADL are environment-directed tasks needed for independent living — cooking, managing money and medicines.
• Q: What is the maximum score on the Barthel Index and on the FIM? A: Barthel 100 (10 items, steps of 5); FIM 126 (18 items scored 1–7, minimum 18).
• Q: In hemiplegia, which limb is dressed first and why? A: The affected limb goes in first and comes out last, because the garment can be manoeuvred over a stiff or flaccid limb more easily when there is maximum free fabric.
• Q: A patient contributes 60% of the effort in a transfer. What is the FIM score? A: 3 — moderate assistance, since the contribution is between 50% and 74%.
• Q: Why do we prefer occupation-based activity over rote exercise? A: Meaningful occupation improves motivation, attention and skill transfer to real life; exercise trains a component without guaranteeing that the task itself is performed.
• Q: What is backward chaining and where would you use it? A: The therapist completes all but the last step and the patient finishes it, so every trial ends in success — useful in dementia, learning disability and brain injury.
• Q: Name the four P's of energy conservation. A: Plan, Prioritise, Pace and Position — taught in COPD, cardiac disease, cancer-related fatigue and multiple sclerosis.
• Q: Why is C6 a key level in tetraplegia ADL training? A: Active wrist extension gives a tenodesis grasp, which allows independent feeding, grooming, upper-body dressing and often self-catheterisation and sliding-board transfers.
• Q: State three joint-protection principles for rheumatoid arthritis. A: Respect pain, use the largest and strongest joints available, and avoid prolonged static grip and positions that push joints toward deformity.
• Q: Convert a 3-MET activity to kcal/min for a 60 kg patient. A: 3 × 3.5 × 60 ÷ 200 = 3.15 kcal/min.
• Q: Which Indian law defines benchmark disability and how does your ADL assessment relate to it? A: The Rights of Persons with Disabilities Act, 2016 sets benchmark disability at 40% across 21 specified conditions; ADL findings feed the functional part of the certification assessment on the UDID system.
• Q: Why might a Western ADL checklist under-report dependence in an Indian patient? A: It usually omits squat toileting, floor sitting, bucket bathing, eating with the hand and chapati making — tasks that are essential here and are often the first to fail.

Common mistakes

• Quoting a Barthel or FIM total without naming the version and the maximum (Barthel has 0–20 and 0–100 forms; the Modified Barthel differs again).
• Scoring what the patient *can* do on demand, or what the family reports, instead of observed habitual performance — and not recording which it was.
• Confusing eating with feeding, or listing cooking and shopping as BADL.
• Treating exercise and modalities as the whole treatment; a preparatory method with no ADL practice attached does not transfer.
• Grading several variables at once (heavier, longer and harder) so that neither progress nor regression can be attributed.
• Forgetting condition precautions during ADL drill — total hip angles, sternal precautions, no-Valsalva in cardiac cases, swallow safety.
• Discharging without carer training, a written home programme in the family's language, and a re-scored outcome measure.
