Abstract
Background: Blood flow restriction (BFR) applied during low intensity resistance training (LIRT) exercise produces hypertrophy and strength gains equivalent to traditional training. The effectiveness of BFR-LIRT on persons with Parkinson Disease (PD) has not been investigated.
Objective: To determine the effects of BFR-LIRT on a recreationally active person with PD in regards to function, strength, Restless Leg Syndrome (RLS) and safety. Methods: A single subject, A-B-A design was utilized. Each phase lasted 6 weeks. Outcome measures included: 30-second sit-to-stand; Timed Up and Go (TUG); RLS Questionnaire; 3-RM of Cybex Leg Press (LP); Leg Curl (LC); and Leg Extension (LE) measured every 3 weeks for 18 weeks. The intervention phase (B, weeks 6–12) included four lower extremity resistance exercises (LP, LC, LE, calf presses on the LP) with the addition of BFR. The two standard deviation band method was used to determine significance.
Results: All outcome measures except the TUG improved significantly by the end of intervention phase.
Conclusion: The combination of BFR with LIRT safely lead to an increase in lower extremity strength and function in a person with PD, while decreasing their RLS (improvement from moderate to mild symptoms) resulting in a better quality of life for the participant.
