Abstract Background This factorial, assessor-blinded, randomized, and controlled study compared the effects of perturbation-induced step training (lateral waist-pulls), hip muscle strengthening, and their combination, on balance performance, muscle strength, and prospective falls among older adults. Methods Community-dwelling older adults were randomized to 4 training groups. Induced step training (IST, n = 25) involved 43 progressive perturbations. Hip abduction strengthening (HST, n = 25) utilized progressive resistance exercises. Combined training (CMB, n = 25) included IST and HST, and the control performed seated flexibility/relaxation exercises (SFR, n = 27). The training involved 36 sessions for a period of 12 weeks. The primary outcomes were the number of recovery steps and first step length, and maximum hip abduction torque. Fall frequency during 12 months after training was determined. Results Overall, the number of recovery steps was reduced by 31% and depended upon the first step type. IST and CMB increased the rate of more stable single lateral steps pre- and post-training than HST and SFR who used more multiple crossover and sequential steps. The improved rate of lateral steps for CMB exceeded the control (CMB/SFR rate ratio 2.68). First step length was unchanged, and HST alone increased hip torque by 25%. Relative to SFR, the fall rate ratios (falls/person/year) [95% confidence interval] were CMB 0.26 [0.07–0.90], IST 0.44 [0.18–1.08], and HST 0.30 (0.10–0.91). Conclusions Balance performance through stepping was best improved by combining perturbation and strength training and not strengthening alone. The interventions reduced future falls by 56%–74% over the control. Lateral balance perturbation training may enhance traditional programs for fall prevention.

Background: Active rehabilitation has an important role in the management of patellofemoral pain syndrome (PFPS). Although some studies have shown the benefit of hip-muscle strengthening, the effect of combining hip-muscle stretching with strengthening has not yet been defined. Purpose: To evaluate the effect of combined strengthening of the hip external rotators and abductors and stretching of the hip internal rotators on pain and function in patients with PFPS. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: A total of 109 patients with PFPS (75 female and 34 male; mean age, 31.6 ± 10.8 years) were first randomly assigned to protocol A (n = 67) of the A-B arm (AB group; standard rehabilitation) or protocol B (n = 42) of the B-A arm (BA group; standard rehabilitation with strengthening of the hip external rotators and abductors and stretching of the hip internal rotators). Each protocol consisted of 3 sessions a week for 4 weeks. After a washout period, corresponding to a symptom-free period, rehabilitation programs were crossed over. A visual analog scale (VAS) evaluating perceived pain, the Functional Index Questionnaire (FIQ), and the Kujala score were administered at baseline, the end of each rehabilitation protocol, and 12 weeks after the completion of the second protocol for each group. Results: Until the final follow-up, VAS, FIQ, and Kujala scores were significantly improved in both the A-B and B-A arms ( P < .05 for all). Compared with protocol A, protocol B provided significant improvement in terms of pain and function in both the BA (VAS and Kujala; P < .001) and AB (VAS and Kujala; P < .001) groups. Conclusion: Combined strengthening of the hip abductors and external rotators with stretching of the hip internal rotators provided better outcomes, which were maintained for at least 12 weeks, in terms of pain and function in patients with PFPS.

Pilot Randomized Controlled Trial

Objective: To evaluate the effectiveness of acupuncture for pain relief and function improvement in patients with knee osteoarthritis and to determine the feasibility of an eight-week acupuncture intervention. Design: Pilot randomized controlled trial. Setting: Three teaching hospitals in China. Subjects: Patients with knee osteoarthritis (Kellgren grade II or III). Interventions: Patients were randomly assigned to an eight-week (three sessions per week) intervention of either traditional Chinese acupuncture or sham acupuncture. Main measures: The primary outcome was response rate—the proportion of patients achieving score ⩾36% decrease in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function at week 8 compared with baseline. Secondary outcomes included pain, function and quality of life. Results: Of 42 patients randomized, 36 (85.7%) completed the study. There was no significant difference in response rate between the traditional Chinese acupuncture and control groups: 61.9% (13 of 21) versus 42.9% (9 of 21) achieved score ⩾36% decrease in WOMAC pain and function at week 8 ( P = 0.217). The sum of WOMAC pain and function scores at week 8 was 11.6 (9.1) in the traditional Chinese acupuncture group compared with 16.3 (10.9) in the control group ( P = 0.183). There was no significant difference between groups. Three adverse events were recorded and were classified as mild. Conclusion: It showed that three sessions per week acupuncture intervention of knee osteoarthritis was feasible and safe. No difference was observed between groups due to small sample size. Larger (sample size ⩾ 296) randomized controlled trials of this intervention appear justified.
