There are only 20 job adverts for new physiotherapists entering the NHS workforce, the Chartered Society of Physiotherapy has said.
Recruitment freezes appear to be impacting the number of newly qualified physiotherapists trying to get their first NHS job, the CSP said as it called on Government officials to act.
This year 3,000 physiotherapy graduates will be finishing their studies and looking for work, the CSP said.
NHS Jobs, the health service recruitment website for jobs in England, has just 20 entry level jobs currently on offer, according to CSP analysis.
And a poll of 1,800 physiotherapists found 22% said that recruitment of clinical staff is partially paused in their organisation and 11% reported a total pause.
Concerns have been raised that UK-trained physiotherapists are seeking work abroad due to 鈥渉ow hard it is to break into the NHS鈥.
The professional body highlighted how 300,000 people are waiting for musculoskeletal treatment in England alone.
Newly qualified physiotherapists can help bring down this waiting list it said, as well as bring down waits for respiratory problems, neurological conditions, and provide post-surgical rehab.
The CSP has written to the Department of Health and Social Care, calling for all newly qualified clinicians to be offered an NHS role.
Ash James, director of practice and development at the CSP, said: 鈥淚t is absurd that with public concern about waiting lists, hundreds of capable and committed graduates are being locked out of the NHS.
鈥淭hese are professionals who could be seeing up to 15 patients a day for musculoskeletal issues, immediately easing pressure on overstretched services and reducing delays.
鈥淚f every graduate had a job, we could begin to cut waiting times now.鈥
Sarah-Jane Ryan, head of practice, learning and development at the School of Education, Sport and Health at the University of Brighton, said: 鈥淭his year, most of my students don鈥檛 have roles lined up which is something we haven鈥檛 seen for a long time.
鈥淓ven first and second year students are now talking about working abroad, because they鈥檙e hearing how hard it is to break into the NHS.
鈥淲e鈥檙e at risk of losing a whole generation of physios at a time when we urgently need them.鈥
She said these students 鈥渘ow face the reality of being shut out of the system they were inspired to work in,鈥 adding: 鈥淚t鈥檚 not just a workforce issue 鈥 it鈥檚 a moral one.
鈥淭hey鈥檝e made sacrifices and trained for a profession they believe in.
鈥淧lacement teams have invested in them, and we know there is a rehab need.鈥
The Department of Health and Social Care has been approached for comment.
