To compare the efficacy of remote rehabilitation training versus in-hospital rehabilitation training in improving motor function and quality of life in patients with Parkinson's disease (PD).

Objective:To compare the differences in the rehabilitation effects of resistance training on elderly individuals with sarcopenia and those suffering from sarcopenia possibly.Method:A total of 64 elderly people aged 60 to 80 years old were selected,including 36 diagnosed sarcope-nia patients and 28 potential sarcopenia patients with decreased physical function.They underwent resistance muscle strength training for 4 weeks each.The effects of resistance training on body composition,muscle strength,balance function and fall risk,cardiopulmonary endurance,instrumental activities of daily living(IADL),and quality of life were analyzed.Result:After 4 weeks of training,both groups showed significant improvements in grip strength,30 second bending frequency,30 second sitting frequency,knee extension strength and single leg standing time,Berg balance scale(BBS),and timed up and go test(TUGT)(P<0.05 for all),but there was no significant change in body composition.The improvement in grip strength and six-minute walk test(6MWT)in the elderly possi-bly suffering from sarcopenia was more significant than that in the sarcopenia group(P<0.05).The sarcopenia group showed significant improvement in multiple dimensions of IADL and quality of life.There was no signif-icant difference in the changes in IADL and quality of life between the two groups.Conclusion:Compared with elderly people with sarcopenia,four weeks of early resistance training can more significantly improve muscle strength and cardiorespiratory endurance in potentially elderly people with sarcope-nia who have already experienced a decline in somatic function but have not yet met the diagnostic criteria for sarcopenia.

Objective To observe the differences in motor function and quality of life among mild-to-moderate Parkinson's disease(PD)patients with or without freezing of gait(FOG),and the correlation of FOG to motor function and quality of life. Methods From April,2021 to December,2022,132 mild-to-moderate PD patients aged 60 to 80 years were selected from Peking Union Medical College Hospital,and were divided into FOG group(n = 43)and non-FOG group(n = 89)according to the clinical features.They were assessed with Freezing of Gait Questionnaire(FOGQ),Berg Balance Scale(BBS),Timed"Up&Go"Test(TUGT),Five Times Sit to Stand Test(FTSST),isokinetic muscle strength,Unified Parkinson's Disease Rating Scale(UPDRS)and 39-item Parkinson's Disease Question-aire-39(PDQ-39). Results The BBS score was lower(Z =-2.354,P<0.05),and the TUGT,FTSST,UPDRS part 2 and part 3 scores,and the Parkinson's disease summary index(PDSI)were higher in FOG group than in non-FOG group(Z>3.074,t = 2.748,P<0.01).FOGQ score correlated with BBS score,UPDRS Part 2 and Part 3 scores,and PDSI(|r|>0.392,P<0.001). Conclusion FOG would impair motor function,activities of daily living and quality of life in mild-to-moderate PD pa-tients,and increase the risk of falls.

Freezing of gait (FOG) is a common motor manifestation in the middle and late stages of Parkinson's disease. It is also a major cause of falls and may lead to disability, making it important to identify and treat FOG effectively. In this paper, we review the common and practical methods of FOG detection in clinical and research studies, with a view to provide clinical reference.
