Physiotherapy — Procedure Guide, Recovery & Risks | MyMedicPlus

Physiotherapy (physical therapy) is an evidence-based allied health discipline that uses manual therapy techniques, structured exercise prescription, electrotherapy modalities (TENS, therapeutic ultrasound, interferential therapy), hydrotherapy, and patient education to restore movement, function, and quality of life. It addresses a wide spectrum of conditions across musculoskeletal, neurological, cardiorespiratory, and paediatric medicine. Physiotherapists complete a university degree-level qualification (BSc, MSc, or DPT) and are regulated by national bodies such as the Health and Care Professions Council (HCPC) in the UK and the American Board of Physical Therapy Specialties (ABPTS) in the USA. Physiotherapy is delivered in acute hospital wards, outpatient clinics, rehabilitation centres, community settings, and increasingly via tele-rehabilitation platforms. It is recommended as first-line management for most musculoskeletal conditions before surgical intervention is considered. Physiotherapy (physical therapy) is a healthcare profession and clinical discipline that uses evidence-based physical interventions to restore, maintain, and maximise physical function, movement quality, and independence. Physiotherapists assess musculoskeletal, neurological, cardiorespiratory, and paediatric conditions, designing individualised treatment programmes using therapeutic exercise, manual therapy, electrotherapy, and patient education. Physiotherapy is both a primary treatment (for musculoskeletal pain, sports injuries, balance disorders) and an adjunct to surgical or medical care (post-operative rehabilitation, stroke recovery, COPD management). It is delivered in hospitals, outpatient clinics, community settings, sports environments, and patients' homes. Physiotherapists work across all age groups from neonates (neonatal physiotherapy) to elderly patients (geriatric falls prevention, frailty rehabilitation). The profession uses standardised outcome measures — including the Numeric Pain Rating Scale (NPRS), patient-specific functional scale, Berg Balance Scale, and 6-Minute Walk Test — to monitor progress and guide treatment decisions.

Physiotherapy is indicated across a broad range of clinical conditions. Musculoskeletal indications include acute soft-tissue injuries (sprains, strains, muscle tears), fracture rehabilitation, tendinopathies (rotator cuff, Achilles, patella), osteoarthritis, rheumatoid arthritis, chronic low back pain, neck pain, and scoliosis. Post-surgical rehabilitation encompasses total hip and knee replacement, spinal fusion, ACL reconstruction, rotator cuff repair, and post-mastectomy shoulder rehabilitation. Neurological rehabilitation is indicated for stroke, Parkinson's disease, multiple sclerosis, cerebral palsy, spinal cord injury, and acquired brain injury. Cardiorespiratory physiotherapy is used in COPD, cystic fibrosis, post-cardiac surgery, and ICU weaning. Pelvic floor physiotherapy addresses incontinence, pelvic organ prolapse, and obstetric perineal trauma. Contraindications include acute fractures requiring immobilisation, active deep vein thrombosis in the affected limb, and undiagnosed malignancy presenting as musculoskeletal pain — a thorough clinical assessment identifies red flags before commencing treatment.

A physiotherapist conducts a structured initial assessment including subjective history (symptoms, mechanism, function, goals) and objective examination (range of motion, muscle strength, neurological status, gait, and special tests). Treatment is tailored to the assessment findings and patient goals. Manual therapy encompasses joint mobilisation and manipulation, soft-tissue massage, myofascial release, neural mobilisation, and dry needling. Exercise therapy involves progressive strengthening, neuromuscular control, balance, cardiovascular conditioning, and functional task training. Electrotherapy modalities — TENS for pain modulation, therapeutic ultrasound for soft-tissue healing, interferential therapy for deep analgesia — are used as adjuncts. Hydrotherapy exploits the buoyancy, resistance, and thermal properties of water (34–36°C) to allow pain-free early loading in orthopaedic and neurological rehabilitation. Respiratory physiotherapy uses airway clearance techniques (active cycle of breathing, positive expiratory pressure, vibration) and breathing re-education. A structured home exercise programme extends therapy between supervised sessions. Manual therapy techniques include joint mobilisation (Maitland grades I–IV), joint manipulation (grade V — high-velocity low-amplitude thrust), and neural mobilisation for radiculopathy. Electrotherapy modalities include transcutaneous electrical nerve stimulation (TENS), therapeutic ultrasound, interferential therapy, and neuromuscular electrical stimulation (NMES). Exercise prescription follows periodisation principles with progressive overload. Hydrotherapy (aquatic physiotherapy) uses water buoyancy to facilitate movement in patients with pain-limited land-based exercise tolerance. Each session is 30–60 minutes; treatment courses typically involve 6–12 sessions with home exercise programme compliance determining outcomes.

Exercise-based physiotherapy reduces chronic low back pain disability by 30–40% and is the first-line recommendation before surgery or opioid analgesia in all major guidelines. Physiotherapy after total knee replacement reduces the time to achieving full range of motion by 30–40% and improves functional outcomes at 6 months. Post-stroke motor rehabilitation with task-specific training improves functional independence in 60–70% of patients when initiated within the first 4 weeks. Physiotherapy after ACL reconstruction reduces re-rupture risk by 50% compared with surgery alone without rehabilitation. Pulmonary rehabilitation in COPD reduces hospitalisation rates by 26–39% and improves 6-minute walk distance by a clinically significant 43–60 metres. Pelvic floor physiotherapy cures stress urinary incontinence in 40–60% of women and improves it in a further 20–30%.

Physiotherapy is among the safest interventions in clinical medicine. Temporary post-session soreness or transient increase in pain is common in the first 2–4 sessions as tissues adapt to loading — this is normal and should be distinguished from an adverse response. Aggressive spinal manipulation carries very low but real risks: vertebral artery dissection associated with cervical manipulation is estimated at 1 in 400,000–1,000,000 manipulations. Vigorous manual therapy in patients with undiagnosed osteoporosis may risk fracture; bone density assessment is recommended before aggressive spinal mobilisation in at-risk populations. TENS is contraindicated in patients with implanted electronic devices (pacemakers, nerve stimulators) at the placement site and over open wounds. Electrotherapy should not be applied over areas of active malignancy, skin infections, or absent sensation.

Session frequency is typically 2–3 times weekly in the acute-subacute phase, reducing to weekly or fortnightly as the patient progresses and takes ownership of their home programme. Acute conditions (ankle sprain, simple soft-tissue injury) may resolve in 4–8 sessions over 4–6 weeks. Post-surgical rehabilitation continues for 3–6 months for major joint replacement or ligament reconstruction. Neurological rehabilitation for stroke or brain injury is often lifelong, with periods of intensive input alternating with self-managed maintenance. The final goal of physiotherapy discharge is self-management: the patient understands their condition, can perform their exercise programme independently, and knows how to seek help if symptoms recur. Long-term activity modification, ergonomic advice, and adherence to a maintenance exercise programme are key to preventing recurrence of musculoskeletal conditions.
