Sarcopenia (Age-Related Muscle Loss)
Written by Dr Joshua Hatch, Musculoskeletal GP, RACGP Fellow, Diploma in Musculoskeletal Medicine (FSEM UK).
Sarcopenia means the muscles have become weaker and poorer in quality than expected for a person’s age, to the point that daily function and safety are affected. It is not a normal or inevitable part of getting older, and it can start earlier in life. Weakness that comes on quickly, is one-sided or comes with other neurological symptoms needs a different assessment first.
Assessment focuses on what the muscles can do. Grip strength and a timed chair-stand test are simple measures, and walking speed shows how severe the problem is. A medication review, a look at protein and energy intake, and checks for conditions that cause weakness are part of the assessment. Because sarcopenia and osteoporosis often occur together, bone health and falls risk are usually considered at the same time.
First-line care is a progressive resistance programme, ideally supervised at first by a physiotherapist or exercise physiologist, combined with balance training and adequate protein. The trial evidence is mostly small and the benefits for any one person cannot be guaranteed. Clinic treatments such as shockwave or injections have no role. Seeing a GP is the right starting point if strength, walking pace or stamina has declined.
This page is general information, not a substitute for individual medical advice.
Common symptoms
- A gradual loss of strength or stamina
- Difficulty standing from a chair or climbing stairs
- A slower walking pace than before
- A fall or near-fall, or unintentional weight loss

Evidence for twelve treatment options in sarcopenia (age-related muscle loss)
This is not a fixed ladder or a package of treatments. Every option is assessed independently against this diagnosis, including treatments with limited direct research that may still be reasonable for a clearly defined tissue target. The evidence level, likely benefit, risks, cost and alternatives are weighed at consultation.
Foundation: diagnosis, education and rehabilitation
The part of care with the broadest relevance. For many people it is enough on its own; other options are judged against it, not automatically added after it.
Diagnosis, education and progressive rehabilitation Working out what is driving the pain, explaining what your imaging does and does not mean, and building a graded loading plan you can actually follow. The treatment
What it involves
Assessment to identify the likely pain source, an explanation of what the diagnosis means, adjustment of the loads that aggravate it, and a progressive strength and conditioning plan, with weight management where that is clinically relevant.
What the evidence shows
A 2026 meta-analysis of 13 randomised trials (546 older adults with sarcopenia) found resistance exercise improved grip strength by 2.95 kg, walking speed by 0.15 m/s, muscle mass index by 0.25 kg/m2 and five-rise chair-stand time by 1.79 s (Li, BMC Geriatr 2026). A second 2026 meta-analysis of 12 trials (652 participants) found moderate gains in knee strength, walking speed and the Timed Up and Go test, but no clear difference in daily function or quality of life (Alsubaie, BMC Geriatr 2026). The trials were small, and for falls the Cochrane review (Sherrington 2019; 108 trials) found the benefit came from balance and functional exercise, with the effect of resistance training alone on falls uncertain.
Pairing reviewed 2026-10-31.
Where it fits
The core of care: progressive resistance training with balance work, ideally supervised at first, alongside adequate protein and review of medicines. Benefits for any one person cannot be guaranteed.
Muscle and symptom-modifying options
Useful only when the examination identifies the tissue they target or when short-term pain control creates a useful rehabilitation window.
Wet needling and trigger point injection (trigger point injection) A fine needle into a tender band of muscle, with a small volume of dilute glucose solution injected through it. Not a treatment for this
What it involves
The needle is placed into the tender muscle band and a small volume of 5% glucose with a very dilute local anaesthetic (0.02-0.08%) is injected. Often done in the same visit as your assessment, and usable where the tender area sits deeper. Dry needling (the same technique with nothing injected) is not offered here.
What the evidence shows
A PubMed search in October 2026 for dry needling, wet needling or trigger point injection in sarcopenia found no clinical study. The nearest evidence is traditional acupuncture, a different procedure: a 2025 meta-analysis of 10 small trials reported gains in muscle mass and grip strength against usual care while noting the limited number and quality of the trials (Niu, Front Public Health 2025), and one small randomised study found no difference from no treatment (Soares Mendes Damasceno, J Aging Res 2019). Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.
Pairing reviewed 2026-10-31.
Where it fits
Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
Ultrasound-guided injections Guidance means the needle can be seen reaching the target. What goes into the needle depends on the diagnosis. Not a treatment for this
What it involves
The injection is performed under ultrasound so the needle can be watched into the target structure. What is injected is decided by the diagnosis, and corticosteroid is used sparingly, for the reasons set out below.
What the evidence shows
A PubMed search in October 2026 for ultrasound-guided, corticosteroid, intramuscular or joint injections in sarcopenia returned 43 records and none tested an injection procedure as a treatment for sarcopenia in people. The human studies were of hormone medicines (testosterone, nandrolone) or treated sarcopenia only as a risk factor; the rest were animal work. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.
Pairing reviewed 2026-10-31.
Where it fits
Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
V-ACTOR vibration therapy (vibration therapy) Low-frequency vibration applied over tender muscle. Not a shockwave, despite sharing the machine. Not a treatment for this
What it involves
A vibration handpiece is moved over the tender muscle and fascia for a few minutes. It runs from the same STORZ MASTERPULS icon console as radial shockwave but is a separate handpiece delivering a different, gentler form of energy. No needles, no anaesthetic, no downtime.
What the evidence shows
No study has tested V-ACTOR or other hand-held local vibration in people with sarcopenia (PubMed, October 2026). The nearest evidence is whole-body vibration on a standing platform, a different treatment: a 2026 meta-analysis of 6 randomised trials (202 older adults with sarcopenia) found moderate gains in leg strength (SMD 0.50) and physical performance (SMD 0.50) but no gain in muscle mass (Beom, Sci Rep 2026), while a 2021 meta-analysis found no significant effect on knee strength or walking speed (Lu, BMC Geriatr 2021). Local vibration trials in older adults have been in people without sarcopenia. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.
Pairing reviewed 2026-10-31.
Where it fits
Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
Energy-based treatment options
Radial pressure wave, focused shockwave and EMTT have different targets and different evidence. They are assessed separately rather than treated as one category.
Radial or focused shockwave? Read the overviewRadial shockwave (radial pressure wave) Broad treatment across tender muscle and fascia, close to the surface. Not a treatment for this
What it involves
A handpiece is moved over the tender tissue while ballistic pressure pulses are delivered, using a transmitter head chosen for the tissue, including heads shaped for fascia and for the muscle either side of the spine. The pulse is strongest at the skin and weakens with depth, so this is mainly a myofascial treatment, though it can reach deeper in some areas. No anaesthetic, no downtime, usually a course of sessions about a week apart.
What the evidence shows
A PubMed search in October 2026 for shockwave therapy in sarcopenia found no completed study. One registered trial protocol plans to add shockwave and kinesio taping to exercise in 94 older adults with sarcopenia (Lu, BMC Geriatr 2025; ChiCTR2200064269); it has no results yet, and its design will not separate the shockwave from the taping. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.
Pairing reviewed 2026-10-31.
Where it fits
Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
Focused shockwave (ESWT) A true shock wave converging at depth: for tendon, joint, ligament and bone. Not a treatment for this
What it involves
A focused system generates an acoustic shock wave that converges at a focal point set at a defined depth, concentrating the energy where the target is. This is the form used for tendon, joint, ligament and bone. Typically four to six sessions about a week apart, no anaesthetic and no formal downtime.
What the evidence shows
A PubMed search in October 2026 for shockwave therapy in sarcopenia found no completed study. One registered trial protocol plans to add shockwave and kinesio taping to exercise in 94 older adults with sarcopenia (Lu, BMC Geriatr 2025; ChiCTR2200064269); it has no results yet, does not state whether radial or focused shockwave is used, and will not separate the shockwave from the taping. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.
Pairing reviewed 2026-10-31.
Where it fits
Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
EMTT (magnetotransduction therapy) High-energy magnetic pulses applied over the area. Usually painless, no contact. Not a treatment for this
What it involves
You sit with the applicator positioned over the area for a short session. It is usually painless and needs no gel or skin contact. It is usually given as a course, commonly alongside shockwave.
What the evidence shows
No study has tested EMTT (magnetotransduction therapy) in sarcopenia (PubMed, October 2026). The nearest evidence is a pulsed electromagnetic field (PEMF) device, a different treatment: one non-randomised study of 41 older adults with sarcopenia reported knee-extension strength rising from 13.1 to 18.6 kgf and Timed Up and Go time improving from 23.1 to 18.7 seconds after 12 sessions, with no change in calf circumference and no significant change over time in the SARC-F+CC score (Leonardo, Life 2025). Without randomisation it cannot separate the device from other effects. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.

Where it fits
Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
Biologic and joint injection options
Each injection is assessed independently for the named diagnosis. Cost, uncertainty, likely benefit, risks and alternatives are part of the decision.
Platelet-rich plasma (PRP) Your own blood, concentrated and injected under ultrasound guidance. Not a treatment for this
What it involves
Blood is taken from your arm, spun to concentrate the platelets, and injected into the target under ultrasound guidance in the same appointment.
What the evidence shows
A PubMed search in October 2026 for platelet-rich plasma in sarcopenia returned 6 records and none tested it as a treatment in people: they were animal studies, reviews, or used the abbreviation PRP for something else. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.
Pairing reviewed 2026-10-31.
Where it fits
Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
Prolotherapy (dextrose) A course of dextrose injections into and around the structure and its attachments. Not a treatment for this
What it involves
Hypertonic dextrose is injected at the tender ligament and tendon attachments, and into the joint where relevant, usually as a series of treatments a few weeks apart.
What the evidence shows
A PubMed search in October 2026 for prolotherapy, dextrose, hyaluronic acid or viscosupplementation injection in sarcopenia found no clinical study of prolotherapy; dextrose appeared only as the placebo in supplement trials. Prolotherapy targets ligaments and tendons, and sarcopenia is a whole-body loss of muscle strength, so there is no tissue for it to treat. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.
Pairing reviewed 2026-10-31.
Where it fits
Not offered for sarcopenia, because the injection has nothing to treat in a whole-body loss of muscle. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
Viscosupplementation (hyaluronic acid) A gel-like injection into an arthritic joint. Widely used, and genuinely contested. Not a treatment for this
What it involves
One or a short series of hyaluronic acid injections into the joint under ultrasound guidance.
What the evidence shows
A PubMed search in October 2026 for hyaluronic acid injection in sarcopenia found no study using it as a treatment; hyaluronic acid appeared only as a drug carrier in animal work, as a cosmetic filler, or in knee osteoarthritis research where sarcopenia was a background factor. Hyaluronic acid acts inside a joint, and sarcopenia is not a joint problem. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.
Pairing reviewed 2026-10-31.
Where it fits
Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
Nerve-targeted options
Relevant when examination identifies a superficial neuropathic pattern or a compressed peripheral nerve, not simply because pain is present.
Lyftogt perineural therapy (perineural injection therapy) A series of small dilute dextrose injections just under the skin, over tender superficial nerves. Not a treatment for this
What it involves
Small injections of low-concentration dextrose, usually 5%, placed just beneath the skin along tender superficial nerves. Given as a series of short sessions.
What the evidence shows
A PubMed search in October 2026 for perineural injection, neural prolotherapy, subcutaneous dextrose, glucopuncture or neurofascial injection in sarcopenia returned no records. Sarcopenia is a loss of muscle strength and quality, not a painful nerve problem. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.

Not offered for sarcopenia. Care is a progressive resistance and balance programme, adequate protein, medication review and falls prevention.
Ultrasound-guided nerve hydrodissection Fluid placed around a nerve to free it from the surrounding tissue. Not a treatment for this
What it involves
Under ultrasound, fluid is placed in the plane around the nerve to separate it from the tissue that is tethering or compressing it.
What the evidence shows
A PubMed search in October 2026 for nerve hydrodissection in sarcopenia found no study. Hydrodissection frees a trapped nerve, and sarcopenia is not a nerve entrapment. Guidance (ANZSSFR consensus, Zanker, J Cachexia Sarcopenia Muscle 2023; EWGSOP2, Cruz-Jentoft, Age Ageing 2019) places treatment in resistance exercise, nutrition and falls prevention.

This is general information only and suitability is assessed individually. Treatments with limited or condition-dependent evidence may still be discussed, but only with clear explanation of the uncertainty, the expected benefit, risks, cost and alternatives. Red flags, progressive neurological symptoms or suspected serious pathology require a different pathway.
Every treatment above is described in full on the non-surgical treatments page, including what each one is used for and what the evidence supports. Ratings apply to the named diagnosis; an adjacent muscle, tendon, joint or nerve problem is assessed as a separate target. The method behind the ratings, and the treatments not offered, are set out on the evidence page.
Corticosteroid injection is reviewed separately for each diagnosis.
Cortisone reliably reduces pain in the short term, and that can be genuinely useful when pain is stopping you sleeping or moving enough to rehabilitate. Beyond that window the picture changes. A systematic review of 41 randomised trials and 2,672 participants found that corticosteroid injection reduced pain in the short term but that the effect reversed at intermediate and long term; in pooled analysis for lateral epicondylalgia the short-term effect was large (SMD 1.44, 95% CI 1.17 to 1.71) while no intervention was favoured at 26 weeks (-0.40, -0.67 to -0.14) and at 52 weeks (-0.31, -0.61 to -0.01) (Coombes, Lancet 2010). In a randomised trial in lateral epicondylalgia, 83 per cent of the corticosteroid group had completely recovered or much improved at one year against 96 per cent given a placebo injection, and recurrence ran at 54 per cent against 12 per cent; adding physiotherapy made no significant difference at one year (Coombes, JAMA 2013). In joints, repeated corticosteroid injections have been associated with cartilage loss. It does not repair anything.
So treatment plans are not built around it. Where an injection is the right call, the specific diagnosis and target are reviewed, what is being injected and why is discussed, the number is kept low, and it is paired with the loading work that changes the longer-term course.
When it might still be considered
- Pain severe enough to block rehabilitation
- A clear inflammatory or bursal target on imaging
- A specific short-term goal: a trip, a procedure, a return to work
- Diagnostic use, where the response shows where the pain is coming from
When a cortisone injection is worth doing, and when it is not
Other general conditions
Pain in the same area can come from more than one source, and the label matters less than what the examination and history point to. These are the other guides for this region.
