Not a diagnosis, dose, or listing recommendation. ## What it computes Return the Schwab and England 1969 ADL percent 0-100 from a caller-assigned integer, with a stable label. ## When to use When an agent already has a Schwab and England ADL percent 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 as in Schwab and England 1969 and needs the published score and label. magent does not observe the patient or assign ADL percent. Not Hoehn and Yahr. Not Karnofsky. ## When not to use - Not a medical device. magent does not observe the patient. - Schwab and England 1969 ADL decades 0-100 including 0% vegetative. The caller assigns adl_percent. magent does not examine the patient. - Not Hoehn and Yahr and not Karnofsky. Stable adl_label tokens are not a published class. ## Formula ``` Schwab and England ADL = caller-assigned integer 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 (Schwab and England 1969); max 100; 0% vegetative is scored ``` ## Citation [Projection technique for evaluating surgery in Parkinson's disease](https://wellcomecollection.org/works/uztfjp6k) Schwab RS, England AC In: Gillingham FJ, Donaldson IML, eds. Third Symposium on Parkinson's Disease. Edinburgh: E & S Livingstone; 1969:152-157 DOI: none ## Worked example ### ADL 100 completely independent Given: `adl_percent=100` 1. adl_percent 100 → score 100; max 100; adl_percent 100; completely_independent ### ADL 0 vegetative Given: `adl_percent=0` 1. adl_percent 0 → score 0; max 100; adl_percent 0; vegetative ## Also searched as - Schwab and England - Schwab England ADL - S and E ADL - Parkinson ADL percent - Schwab England 1969 - activities of daily living Parkinson - SE ADL ## Parameters - `adl_percent` (integer, required): Schwab and England 1969 ADL percent 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 as assigned by the caller (100 completely independent, able to do all chores without slowness, difficulty or impairment; 90 completely independent with some slowness, difficulty and/or impairment, might take twice as long; 80 completely independent in most chores, takes twice as long; 70 not completely independent, more difficulty with some chores, three to four times as long in some; 60 some dependency, can do most chores but exceedingly slowly and with much effort; 50 more dependent, help with half, difficulty with everything; 40 very dependent, can assist with all chores but few alone; 30 with effort now and then does a few chores alone, much help needed; 20 nothing alone, can be a slight help with some chores; 10 totally dependent, helpless; 0 vegetative functions such as swallowing, bladder and bowel functions are not functioning, bedridden). 0% vegetative is scored. magent does not observe the patient. ## Bulk (POST) POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement. Method: `POST /api/calc/schwab_england` Max items: 25 Price: unit_amount + extra_item_amount * (n - 1) (unit 5000 atomic, extra 2000 atomic) Status: PREVIEW - 1 to 25 items. Each item uses the same keys as the GET query parameters. - POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows. - The first invalid item fails the whole request (index in the 400 JSON). You are not charged. - HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row. - Catalog misses (empty matches, found=false) stay paid 200s inside that slot. - x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

Returned before settlement; you are not charged. - HTTP 400 `invalid_items`: POST body must be a JSON object with only an items array Returned before settlement; you are not charged. - HTTP 400 `invalid_item_count`: items must be an array of 1 to 25 objects Returned before settlement; you are not charged. - HTTP 400 `invalid_item`: each items entry must be a JSON object Returned before settlement; you are not charged. Shared HTTP 402 and 503: https://magentlab.com/docs/payments ## Related tools - [Modified Hoehn and Yahr](https://magentlab.com/docs/modified-hoehn-yahr) — Echo the caller-assigned Goetz 2004 Table 1 modified Hoehn and Yahr stage (1.0, 1.5, 2.0, 2.5, 3.0, 4.0, or 5.0) with the published description. No stage 0. magent does not examine the patient. - [Barthel Index](https://magentlab.com/docs/barthel) — Sum ten caller-assigned Mahoney 1965 Barthel Index item points and return the published 0-100 total. - [Karnofsky](https://magentlab.com/docs/karnofsky) — Return the Karnofsky 1949 Performance Status 10-100 from a caller-assigned integer, with a stable label. ## Payment Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. - GET the tool with Accept: application/json (do not send Accept: text/html unless you want the human paywall). - HTTP 402 means you have not paid. Decode the base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote. - Sign accepts[0] (exact, EIP-3009) with validBefore = now + maxTimeoutSeconds (600 seconds), or accepts[1] (batch-settlement deposit/voucher) on product GET. Ping and POST {items} stay exact. Magent retries transient facilitator 429/5xx before answering. - Retry the same URL with PAYMENT-SIGNATURE (base64 JSON of accepted and payload). Magent attaches canonical extensions.bazaar on CDP verify/settle; echoing 402 bazaar is optional. - Success is HTTP 200 JSON plus PAYMENT-RESPONSE. exact settles before the tool. batch-settlement verifies (and deposit-settles) before the tool and commits the charge after HTTP 2xx. HTTP 503: retry the same PAYMENT-SIGNATURE. Mint a new exact nonce only after a new HTTP 402. - offered `exact` on eip155:8453: Fixed-price USDC on Base. The buyer authorizes the advertised amount (EIP-3009). magent settles before the tool runs (paymentFlow upfront). extra.assetTransferMethod=eip3009 extra.paymentFlow=upfront. - offered `batch-settlement` on eip155:8453: Payment-channel vouchers claimed later in batches. Exact stays accepts[0]. Same-path POST {items} is still exact. extra.assetTransferMethod=eip3009 extra.paymentFlow=authorization. - not offered `upto`: Not offered. Usage-based: buyer authorizes a ceiling, seller settles the actual amount after work. Reserved for a future metered tool. Not for current calculators or code search. Same-path POST {items} is still scheme exact: one EIP-3009 authorization for GET unit plus $0.002 per extra item. That is not x402 batch-settlement (payment channels / vouchers). Shared HTTP 402 and 503 table: https://magentlab.com/docs/payments Stdio MCP (one process per host): https://magentlab.com/docs/mcp ## Guarantees - HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON. - exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE. - HTTP 402 is unpaid only. Do not sign a second authorization because of a 503. - Execution is timeout-bounded and concurrency-capped. - Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
