简要总结
Osteoarthritis is a common degenerative disease that significantly impacts mobility and disability in older adults. This pilot randomized controlled study aimed to examine the effects of a three-month resistance training program on lower limb muscular endurance, balance performance, pain, and quality of life among patients who had undergone unilateral total knee arthroplasty. Twenty-four participants were randomly assigned to either the experimental group receiving resistance training or the control group receiving routine postoperative rehabilitation. The study evaluates and compares the effectiveness of these interventions to provide insights into incorporating resistance training into postoperative nursing care and recovery programs.
详细描述
This study employed an interventional, experimental design with a three-month follow-up to investigate the effectiveness of a progressive lower extremity resistance training program for patients with osteoarthritis following unilateral total joint arthroplasty. The study adhered to the CONSORT guidelines for reporting clinical trials.
Participants were randomly allocated into two groups:
- Control Group: Received routine postoperative rehabilitation care.
- Experimental Group: Received a progressive lower extremity resistance exercise program in addition to routine care. The program utilized 1-kg ankle weights and included seated knee extension, standing hamstring curls, and hip abduction. Training sessions were performed three times per week for three months, with the training volume progressively adjusted as follows:
- 1st Postoperative Month: Performed on the non-operated limb only (2 sets per exercise).
- 2nd Postoperative Month: Continued on the non-operated limb (3 sets) and introduced to the operated limb (2 sets).
- 3rd Postoperative Month: Increased to 4 sets for the non-operated limb and 3 sets for the operated limb.
Each set consisted of 10 repetitions with a 1-minute rest between sets. Participants also received an illustrated exercise leaflet to enhance safety and adherence.

结局指标
主要结局
Lower Extremity Muscle Endurance
时间窗: A higher number of completed stands means a better outcome (better lower extremity muscular endurance). To ensure safety for postoperative patients, a four-legged walker is placed in front of the chair during testing.
Assessed using the 30-Second Chair Stand Test. This test measures the total number of completed stands a participant can perform from a seated position to a full stand within 30 seconds.
次要结局
- Balance Performance(Shorter completion times (fewer seconds) mean a better outcome (better dynamic balance performance).)
