TCM Formula vs. HMB in Pre-Frail Elders: Muscle Strength and Bone Status (TCM-HMB-PF)

13 maggio 2026 aggiornato da: Jui-Shan Lin, MD, Tri-Service General Hospital

Effects of Traditional Chinese Medicine (TCM) Formula vs. HMB on Muscle Strength and Bone Status in Pre-Frail Elders: A Comparative Study

The purpose of this study is to compare the effects of a standardized Traditional Chinese Medicine (TCM) formula versus beta-hydroxy-beta-methylbutyrate (HMB) on muscle strength and bone health in pre-frail older adults . Pre-frailty is a critical stage where functional decline may still be reversed through proper intervention. The study will enroll 90 participants aged 65 years or older who meet the criteria for pre-frailty. Participants will be randomly assigned to either the TCM group (receiving a standardized herbal powder formula) or the HMB group (receiving nutritional supplement tablets) for 24 weeks . The primary objective is to evaluate the change in handgrip strength from baseline to Week 12 . Researchers will also assess changes in skeletal muscle mass, bone mineral density, and overall physical performance . The goal is to determine if the TCM formula is an effective alternative or complementary intervention for managing geriatric frailty.

Descrizione dettagliata

This is a randomized, open-label, parallel-group comparative study designed to evaluate the clinical efficacy and safety of a standardized Traditional Chinese Medicine formula versus beta-hydroxy-beta-methylbutyrate supplementation in pre-frail older adults . Pre-frailty is identified as a reversible stage between robust health and frailty. This study aims to provide clinical evidence for the Traditional Chinese Medicine formula as an intervention to improve muscle strength, bone health, and physical function. Eligible participants aged 65 years or older who meet 1 to 2 of the 5 Fried frailty phenotype criteria will be randomized in a 1 to 1 ratio. The total study duration for each participant is approximately 26 weeks, including a screening period and a 24-week intervention period. Participants in the Traditional Chinese Medicine group receive a standardized herbal powder formula designed to tonify Qi, Blood, Liver, and Kidney. The total daily dosage is 18 grams, administered as 9 grams twice daily, taken 30 minutes before breakfast and lunch. Participants in the HMB group receive a total daily dose of 3 grams of beta-hydroxy-beta-methylbutyrate, administered as two 0.75-gram tablets twice daily after breakfast and lunch. The primary endpoint is the change from baseline in handgrip strength at Week 12 . Secondary endpoints assessed at Week 12 and Week 24 include changes in skeletal muscle mass, bone mineral density, body fat percentage, gait speed using a 6-meter test, Timed Up and Go test, Five Times Sit-to-Stand test, Fried frailty phenotype status, Clinical Frailty Scale scores, and SF-12 quality of life scores . Safety is monitored throughout the study by assessing adverse events and changes in laboratory parameters, including complete blood count, liver and renal function, and urinalysis . A total of 90 participants (45 per group) is required based on a non-inferiority t-test for the primary endpoint. The calculation assumed a power of 80 percent and a one-sided significance level of 0.025, accounting for an estimated 20 percent dropout rate.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change from Baseline in Hand Grip Strength at Week 12
Lasso di tempo: Baseline and Week 12
Hand grip strength is used as a functional biomarker to reflect overall muscle strength. Measurement will be performed using a standardized JAMAR dynamometer. Participants will follow a standardized procedure: seated position, elbow flexed at 90 degrees, with the forearm in a neutral position using the dominant hand. The "Change" is calculated as the value at Week 12 minus the baseline value . Higher values indicate improved muscle strength.
